Patent DE-3732365-A1 (DE)
Title: Method for the production of high-purity, irregular metal powders by atomising the melt
Inventor: BAECKER JUERGEN
IPC: B22F9/08
Filed: 1987-09-25
Abstract: Method for the production of high-purity, irregular (spattered) metal powder by atomising the liquid metal with low-temperature liquefied gas which is compressed and expanded in a nozzle system in such a way that the liquid metal jet is atomised, the mass flow of liquid gas relative to the mass flow of melt during atomisation being proportioned in such a way that the quantity of heat released by the solidifying melt droplets leads to the vaporisation of the liquefied gas to only a relatively small extent. The heat of compression produced during the compression of the gas is removed from the liquefied gas again in a heat exchanger, advantageously operated with liquid nitrogen, the liquefied gas being cooled to a temperature just above, preferably below, the boiling point at normal pressure.

Patent DE-3834371-A1 (DE)
Inventor: GUSTMANN-WESTPHAHLEN HARTMUT
IPC: A61L2/18
Filed: 1988-10-10
Abstract: A process is described for sterilising pharmaceutical compounds in particle form, in particular macrolide and polyene/macrolide antibiotics such as Nystatin or Amphotericin B. The compound to be sterilised is suspended in an inert organic solvent, reduced to a slurry or dissolved, dialkyl carbonate, in particular dimethyl carbonate, or  beta -propiolactone is added to the solvent as a cold steriliser before or after the introduction of the compound to be sterilised, the cold steriliser is allowed to act on the compound to be sterilised for a sufficiently long period of time for adequate sterilisation, and then the cold steriliser and the solvent are removed. The sterilisation is at least as efficient, and sometimes even more efficient, than with ethylene oxide, the use of which is problematical.

Title: Process for aromatising (flavouring) treated tea
Inventor: SCHULMEYR JOSEF DIPL ING
IPC: A23F3/36
Filed: 1988-11-17
Abstract: Moistened black tea is decaffeinated using carbon dioxide as solvent. The mixture of caffeine, water, aroma constituents and gaseous carbon dioxide arising in the purification of the carbon dioxide (before its reuse in circulation) is let off from the separator vessel and is divided into an aqueous caffeine solution and gaseous aroma fraction by temperature increase at atmospheric pressure. The CO2 which is let off and gassed out transports the aroma components, after dew point reduction by temperature decrease, to decaffeinated dried tea whereon the aroma substances are impregnated.

Patent DE-3840158-A1 (DE)
Inventor: GRUBER HEINZ
IPC: E02D5/76
Filed: 1988-11-29
Abstract: Installing rock anchors in non-cohesive rock, with regard to both the stability of the borehole wall and adequate anchorage in the rock, poses problems which can be solved - if at all - by a time-consuming and costly method in which first of all a cased bore is produced, this bore is pressure-grouted with cement mortar while removing the pipe at the same time, the hardened cement mortar is rebored for the purpose of installing an anchor and the latter is then fixed by cement mortar in the bore then produced. In the method according to the invention, an injection-boring anchor known per se is used which is provided with discharge openings merely at its front area and at the cutter head, cement mortar being passed through the central flushing bore of the anchor at the start of boring, which cement mortar fills the bore in synchronism with the advance of the same and ensures large-volume penetration of the surrounding rock in each case. In this way, reliable and stable positioning of an anchor can be achieved by conventional machine use, even under difficult conditions, namely in the rock mentioned.

Patent DE-3935578-A1 (DE)
Inventor: SCHMITT FRANZ-JOSEF DR
IPC: G06F1/32
Filed: 1989-10-25
Abstract: The cooling power needed for a switching mechanism with switchgear for signal processing can be reduced during those periods when no or only a few of the switchgear items are used for signal processing by reducing the electric power needed for the other unused switchgear so that the signal states remain unchanged with special regard to the timing signal for which, with particularly high elementary frequencies, there is a high dynamic electric power consumption through the conductive capacities of supply lines and the input capacities of the switchgear which is not needed for signal processing. With, for example, a matrix arrangement of the switchgear of a switching mechanism with the "pipeline-like" transmission of a long data signal, especially for concentrators, shifters or other permutation circuits of that type of a network node in data packet transmission systems, the power and cooling requirements can thereby be considerably reduced, especially in periods of low transmission load.

Patent DE-3941824-A1 (DE)
Inventor: BRUCKNER WALTER
IPC: D01D5/098
Filed: 1989-12-19
Abstract: Process for making microfilaments with very small diameters for synthetic yarns or for fabrics in which the microfilaments are drawn from spinning nozzles supplied with molten material through a spinning aperture at high drawing speeds and extended. The microfilaments are to be exposed immediately after leaving the spinning aperture to a stream of hot air surrounding the microfilament like a jacket. This provides continuous cooling of the microfilaments so that, despite the high drawing speed, breakage of the filaments is prevented and the spinning device can continue to be run at high drawing speeds even for very small diameters.
