CeramOptec Safety Fiber: More safety for users of fiber-coupled high-performance lasers

Copper wire conductors with a jacket facilitate the design of active protective devices

CeramOptec Safety Fiber: More safety for users of fiber-coupled high-performance lasers

CeramOptec Safety Fiber (Source: @ CeramOptec GmbH)

Bonn/Livani, 08. March 2019 – CeramOptec, one of the leading international developers and manufacturers of multi-mode optical waveguides made of quartz glass, enhances the safety for users of fiber-coupled high-performance lasers. Safety glass fibers with electrical contacting now facilitate the creation of active protective devices that automatically switch off the laser in the event of fiber breakage or connection failures. To this end, the polyamide jacket of the CeramOptec safety fibers contains two extremely thin copper wire conductors that are integrated into the circuit of the laser system via the usual fiber couplings. In case of a fiber breakage these conductors are destroyed and the circuit is thereby interrupted; contact interruption also happens in the event of malfunctions in the interface area between the fiber and the beam source. Users of medical or industrial lasers are thus reliably protected against the emission of harmful laser radiation.
Since the two copper wires are applied together with the polyamide sheathing after the fiber drawing process, the new fiber concept can be implemented for all standardized CeramOptec glass fibers. All-rounders such as the standard Optran© UV/WF fibers are also available as safety fibers, as are the solarization-free Optran© UVNSS special fibers or the homogenizing Optran© NCC fibers with polygonal core geometry. For optimum coverage of all bending radii and temperature zones, safety fibers are available with copper wire conductors of 50, 100 and 150 micrometers. Custom configurations are also available on request.

High-precision laser-based measurement of internal tube contours

Dimension measurement of metal tubes

High-precision laser-based measurement of internal tube contours

The new laser triangulation system for non-contact measurement of the internal contours of tubes.

The new laser-based gauge developed by Dango & Dienenthal Umformtechnik measures the internal contour of tubes and pipes contact-free and with highest precision. The system is capable of measuring the shape, e.g. ovality, over the complete internal circumference or specific surface features, such as weld seams.

The recently patented system measures the internal contour of seamless metal tubes and longitudinally welded pipes in a non-contact process based on the circular laser triangulation technique. It captures the contour along the complete tube length and generates a complete 3D image of the internal tube wall from the measured data.

In longitudinally welded pipe making, the system can be employed – before welding – to capture the dimension of the weld gap, and – after welding – to measure the weld seam.

The system comes with different measuring ranges for tube diameters between 100 and 1,000 mm. It measures the internal contour at 2,048 points gaplessly distributed around the complete internal circumference of the tube. This corresponds to an angular resolution of 0.2 degrees. The distance measurement takes place with a resolution of one per mille of the measuring range.

The new gauge works on the principle of laser triangulation: A laser, accommodated in the measuring head, projects a line onto the complete internal circumference of the tube wall. The camera, which is also installed in the measuring head, captures the line at 2,048 points distributed around the internal circumference. The software derives the internal tube contour by calculating and aggregating the individual distances from the axis.

Mounted on a carrying arm, during the measurement the measuring head moves through the tube along the central axis, capturing up to 90 profiles per second. Based on these profiles, the complete internal contour can be represented in 3D.

Denis Albayrak, Sales Manager at Dango & Dienenthal Umformtechnik, describes the benefits for producers and processors of tubes and pipes: „For the first time ever, the internal contour of tubes and pipes can be measured with a system designed for use in the rugged environment of industrial tube manufacturing. Made for a measuring range of up to 500 mm radius and highest measuring precision, the gauge is the perfect choice for the exacting requirements of the tube and pipe industry.“

Combining infrared radiation and air management to reduce energy use

Combining infrared radiation and air management to reduce energy use

Infradry systems make printing and coating applications significantly more efficient.

Infradry systems from Heraeus Noblelight make printing and coating applications significantly more efficient, as infrared emitters work in conjunction with a specially developed air management system to reduce drying time.

Drying coatings and inks is an energy-intensive process, which is reason enough to put conventional dryers to the test. Infradry modules combine intensive IR radiation with a controlled air supply and exhaust system to ensure effective drying.

This was accomplished with the help of computational fluid dynamics (CFD) to coordinate radiation and air extraction via computer simulation before the system was built. Initial tests with customer materials confirmed the simulation. The drying speed was up to 20 percent faster than with conventional dryers.

Highly efficient drying
The air management system has been designed to absorb and then remove the moisture that is driven out of the coating by the IR emitters. This accelerates drying by preventing the atmosphere inside the process area from becoming oversaturated.

With a power density that is customized to the application and highly polished reflectors that concentrate the infrared radiation on the substrate surface, the new Infradry systems provide very efficient drying. Their modular construction makes them easily scalable for any working width, and they can be configured with a variety of interfaces. Infinitely variable power ensures exact control of drying.

Powerful twin-tube infrared emitters
There are currently two types of Infradry systems: The Infradry Compact has a very small footprint, and is easily expandable. The Infradry Combi is suitable for larger facilities and is the first drying system in the world to extract the air between the emitters within the infrared emitter field. Unlike conventional dryers, the moisture is extracted directly from the process area, making infrared drying more thorough, as a result.

High-performance twin-tube IR emitters provide the heat for drying inks and dyes. Depending on the application, shortwave or mediumwave emitters can be selected. Shortwave emitters produce very high temperatures very quickly, while mediumwave emitters are considered the most efficient method to dry inks and coatings gently to protect the paper.

Heraeus Noblelight offers the whole range of infrared radiation-from near infrared (NIR) to mediumwave carbon infrared (CIR), conducts trials with the materials, and provides guidance in selecting the optimal emitter for every process.

Microbiologists from Vienna and Brunswick discover rare bacteria that counteract methane production and climate change

Microbiologists from Vienna and Brunswick discover rare bacteria that counteract methane production and climate change

Prof. Dr. Michael Pester, DSMZ, Brunswick

The collaboration of microbiologists Prof. Dr. Alexander Loy and Dr. Bela Hausmann of the Department for Microbiology and Ecosystem Science at the University of Vienna, Austria, with Prof. Dr. Michael Pester of the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures in Brunswick, Germany, has unearthed a rare bacterial species (Candidatus Desulfosporosinus infrequens), which counteracts the excessive formation of the greenhouse gas methane in moors. These bacteria produce energy by reducing sulfate to sulfide, and hold an important control function in the process of methane production. The bacteria are locked in a continuous competitive battle for nutrients with methane-producing archaea; in doing so, they reduce the archaea“s activity, thereby preventing the production of even more methane and helping to obviate additional global warming.

In an article recently published in the renowned journal mBio ( https://doi.org/10.1128/mBio.02189-18), the research team from Vienna and Brunswick employed a systems biology based approach to show that the high activity of the new, sulfate-reducing bacterial species (Candidatus Desulfosporosinus infrequens) can counteract the excessive formation of methane in moors, despite their low occurrence. Moors are natural wetlands and as such responsible for around 30 percent of the worldwide emissions of the greenhouse gas methane. But why do these high-activity bacteria not have a higher rate of reproduction? The researchers think it is because the bacteria have to deal with the acidic pH-environment of the moors. It is therefore probable that these organisms invest their whole energy in the survival of the cell, rather than its growth.

60 years solitary confinement – green test tube biodiversity

Researchers at the Leibniz Institute DSMZ explore metabolic profiles of cyanobacteria

60 years solitary confinement - green test tube biodiversity

Light microscope images of the cyanobacteria © Jörn Petersen & Christian Boedeker, DSMZ

In their quest to find new model systems in cyanobacteria, Associate Professor Dr. Jörn Petersen and Junior Research Group leader Dr. Meina Neumann-Schaal of the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures compared the genome and metabolic profiles of six non-marine cyanobacteria. Their research revealed striking differences in the metabolic repertoire of these organisms und corroborated an entirely unexpected inter-species transfer of primary metabolism genes. Now, the scientists from Brunswick in northern Germany had their findings published in the renowned journal „Genome Biology and Evolution“.

After conducting an extensive comparison of the genome and metabolism of five different cyanobacteria (with Synechocystis sp. PCC 6803 acting as reference strain), the researchers found not only substantial differences regarding the metabolic profiles of these different photosynthetic bacteria, but also demonstrated that the bacteria individually adapt to day-night-cycles. There were large discrepancies between the investigated strains with respect to the assimilation of the greenhouse gas CO2 and its storage in form of carbohydrates. The decrypted genomes form the basis of the understanding of such metabolic variety. For instance, one strain isolated in the Chilean Atacama Desert 60 years ago and ever since practically held in „solitary confinement“, the aptly named Calothrix desertica DSM 106972, contains three times as many genes as the reference organism. The results reveal the urgent necessity to utilise the biodiversity of cultivated cyanobacteria above and beyond the established model systems to allow the full exploitation of their hidden biotechnological potential.

Portrait cyanobacteria
Cyanobacteria are one of the oldest life forms on earth. For a long time, their appearance led scientists to mistakenly rank them among algae („blue-green algae“). But four decades ago, evidence emerged that these organisms represent their own phylum within the world of bacteria. They are one of the most important primary producers of the planet“s oceans and practically invented plant photosynthesis more than three billion years ago. These days they play an important role in biotechnology, including in the production of peptides, amino acids, vitamins and pigments. In the public eye, they mostly make an appearance when producing compounds toxic to humans and animals as a consequence of „algal bloom“ in warm summers. Last year, the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures expanded its collection by incorporating the organism-groups cyanobacteria and protists. Apart from their conservation and supply, the DSMZ in Brunswick also conducts extensive research on these microorganisms.

Ensuring dust limits at the workplace

New sampling system determines the inhalable dust content and the respirable dust fraction that may reach the alveoli.

Ensuring dust limits at the workplace

The new stationary tester VC25 JI equipped with a sampling head for particulate matter.

The new stationary tester VC25 JI developed by Jung Instruments measures particulate matter and the total dust content at workplaces. A new sensor, manufactured exclusively for Jung Instruments, takes precision of flow rate measurement to the next level. The instrument complies with all commonly applied standards as it uses proven, IFA-licensed sampling heads.

Dust pollution legislation requires that in order to comply with dust limits at workplaces the dust content measurement has to be carried out with appropriate precision right next to the workers or directly at the emission source.

Jung Instruments“ new VC 25 JI dust collection system is a stationary sampling unit designed for the measurement of the dust load at workplaces, such as workplaces for welders, or of the kind found at mixing and filling plants in a wide range of industries.

The system measures the inhalable dust content (specified in IFA standard 7284) and the respirable fraction that may reach the alveoli (specified in IFA standard 6068) according to EN 481, using sampling heads for dust and particulate matter licensed by the German IFA Institute for Work Safety.

Central elements of the new instrument are the robust high-precision flow rate meter, manufactured exclusively for Jung Instruments, and the new, extremely user-friendly electronics. The electronic system is designed to always keep the flow rate at exactly 22.5 m3/h, independent of any ambient temperature or flow resistance variations. The instrument comes with a software for self-diagnosis to monitor the filter condition. Fault messages, e.g. about an obstructed or defective filter, are indicated on the LCD.

Thus the instrument combines new technology for controlling the flow rate and for facilitating handling with tried and tested methods for dust measurement.

According to Erwin Jung, founder and managing director of Jung Instruments, his customers benefit not only from the new technology of the instrument: „Many companies use dust sampling systems that have already reached their economic end of life, but not so the measuring heads that work with the samplers. The new VC 25 JI is the solution many operators have been waiting for: They can now continue using the existing measuring heads.“

The cartridges accommodating the flat filters are easy to handle and can be conveniently taken or shipped to a laboratory for subsequent gravimetric and chemical analyses.

Fighting hunger in Africa

Bill & Melinda Gates Foundation supports cassava research in Brunswick (Germany)

Since 2014 the cassava research of the Department of Plant Viruses of the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures GmbH in Brunswick has been funded by the Bill & Melinda Gates Foundation. In December 2018 the Senior Program Officer of the Foundation, Dr. Jim Lorenzen, visited the DSMZ plant virus research group, led by Dr. Stephan Winter, in Brunswick (Germany). As part of a project funded by the Gates Foundation with about 900,000 Euro, the researchers succeeded in finding resistances to African viruses in cassava varieties from South America. The viruses trigger a severe root rot, the Cassava Brown Streak Disease (CBSD), which leads to complete crop loss. So far, African cassava varieties have little resistance to these viruses, often leading to catastrophic crop failures. „As the disease continues to spread from East Africa to Central and West Africa and threatens the growing in these regions, there is an urgent need to take countermeasures,“ explains Doctor Winter. After extensive trials in the Brunswick research greenhouses, the resistant cassava plants from South America were sent to research stations in Kenya, Tanzania, Rwanda, Uganda and Nigeria to cross virus resistance in African varieties. Experiments in South Kivu in Eastern Congo, which were evaluated after one year of field cultivation, proved that virus resistance in South American varieties is maintained in the field.

„The selected variants grow in Africa, retain their viral resistance to CBSD and remain healthy,“ says Dr. Stephan Winter, the world’s leading cassava virus researcher. In Brunswick, Dr. Jim Lorenzen and Dr. Stephan Winter discussed other research projects that, in addition to basic research on the resistance characterization of South American breeding lines, would primarily involve them directly in the breeding work of African partners. This would to make the new research results concretely applicable in Africa in the fight against hunger. „After twelve months of field cultivation, the South American cassava seedlings show excellent resistance characteristics. However, there is still a need for research when it comes to establishing the plants in different growing regions, but the first steps towards resistant cassava plants in Africa have been taken,“ Dr. Winter summarises the current situation.

Cassava as a food plant
Cassava, also known as manioc, is mainly known in this country as tapioca, the starch extracted from the manioc root. It is the most important food plant in sub-Saharan Africa and often the only daily meal for the poor. Cassava cultivation is repeatedly threatened by viral diseases. For some years now, a viral disease has been spreading from the coastal regions of East Africa. It is caused by novel Cassava Brown Streak viruses and destroys the root. The plants perish, the tuber harvest fails and threatening bottlenecks in food supplies repeatedly occur in African countries, especially in Uganda and Tanzania. The further spread of the disease, especially westward, represents an enormous threat potential for the people of countries such as the Democratic Republic of the Congo and Nigeria, where cassava is of outstanding importance in agricultural production and nutrition. Since Dr. Winter became head of the DSMZ Department of Plant Viruses in 1995, viruses of tropical and subtropical plants have been an important field of research in Brunswick. The research team of the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures GmbH aims at the rapid detection of viral diseases in plants in order to effectively combat epidemics and to explore ways of effectively controlling viral diseases.

Innovative Infrared heat reduces energy consumption in coating packaging for food

An infrared system has dramatically reduced energy costs in the coating of board for food packaging.

An infrared system from Heraeus Noblelight has dramatically reduced energy costs in the coating of board for food packaging at the Stroud factory of The Olympic Varnish Company Ltd. By eliminating the use of steam, the new system has also reduced board spoilage caused when there are unanticipated line stoppages.
Heraeus Noblelight will present innovative infrared solutions for drying, curing and converting at the ICE exhibition, which takes place in Munich in March 2019.

Infrared heat replaces hot steam
Olympic Varnish coats a variety of packaging for food products, ranging from sandwiches, cakes and patisserie to fish and pizza. Polymer coatings are applied to act as a double barrier, preventing any seepage or migration of grease or liquid components of the food from inside the packaging or any leeching of materials, which might taint the product into the packaging. The company also applies pigment and/or print to the outside of packaging if required.
The coater line at Stroud has three coating stations and these are used to apply the polymer coats, or pigment coats if necessary. It is important that the board is dried after each coating and previously this had been done by means of steam-heated, hot air driers in the coating line. However, this was very energy-intensive, as the driers had to be kept at temperature throughout each working shift. In addition, if there was a line stoppage, they could not be switched off and so continued to heat any boards held within the driers, leading to product damage.
To solve these problems, it was decided to use infrared for drying and three 7kW carbon medium wave modules were easily retrofitted before each drier. There was no need to remove the driers and today these are merely supplied with ambient, unheated air.
The new IR drying system has been eminently successful, as Bill Petyan, director at the company, confirms, „We now have more flexibility in coating as the IR heaters can be quickly switched on and off, significantly reducing energy costs. We can also tailor the amount of energy we need as the IR modules typically run between 30% and 60% of full load, depending on the type of board and the weight of coating. In addition, we have also installed a system to detect unwanted build-up of boards on the line when this quickly switches off the heaters“

Infrared heat saves energy
Infrared radiation heats the material precisely and efficiently. In contrast to conventional heating infrared heat is transferred without the need of a contact medium like steam or air.
Infrared modules are supplied ready-to-fit and can be integrated directly into the production process. Quick response times allow control of the emitters and help to save heating time, energy and costs.
