Title: Temp. measurement during formation of layers by vapour deposition - uses cermet layer whose resistance varies as function of temp.
Inventor: WECHSUNG REINER DR
IPC: G01K13/00
Filed: 1976-08-05
Abstract: The electrical resistance of a cerium layer is used to measure the temperature.

Title: Vertically slatted venetian blind motor reduction gear - has coupling unit for selective link to horizontal movement or swivel drive
Inventor: TIPPMANN HEINRICH
IPC: E06B9/36
Filed: 1977-02-26
Abstract: The motorised drive is for a venetian blind with vertical slats displaced horizontally and tilted together about their longitudinal axis. These are fastened to retainers movably inserted in a running rail, and tilted by a shaft passing through the retainers, both movements being promoted by a motor unit with reduction gear.

Inventor: BEHRET HEINZ DIPL CHEM DR
IPC: C02F1/72
Filed: 1977-08-05
Abstract: Cyanide-contg. waste water is decontaminated continuously or intermittently. In a 1st step, the cyanide is oxidised to cyanate with a solid, insol. redox system which is converted to the reduced from. In a 2nd step, the redox system is re-oxidised with air-O2 and recycled to 1st step. Pref. redox system contains solid, insol. reversibly reducible quinoid organic cpds., (I), which are mixed with or absorbed on an active C having a large surface. An organic, polymeric binder for (I) can be used. Addn. of chemicals is reduced. Salting of waste waters is prevented. High oxidn. capacity of (I) maintains a high reaction velocity also at low cyanide concns. Use of a solid, insol. system obviates need for control and measuring devices. The active C acts as re-oxidn. catalysts for (I) and provides a large reaction zone.

Title: Foamed crosslinked olefin! polymer articles - prepd. with foamed particles having bulk wt. increased by steaming and cooling
Inventor: HAARDT UDO ING GRAD
IPC: C08J9/232
Filed: 1977-11-30
Abstract: Foamed articles are made as in the parent patent by heating and compressing crosslinked part-contg. olefin polymer particles foamed with light volatile organic blowing agents. The foamed particles used have wt./vol., measured in g/l, 10-500% higher than that of the initial foam particles. In this addn. the foam particles having a higher wt./vol. are produced by treating foam particles having a lower wt./vol. with steam at 80-130 degrees C, and cooling. In steaming, air is displaced from foam particles and replaced by steam. On cooling, steam condenses and the particles shrink with increase of bulk wt., e.e. from 10-20- to 20-100 g/l. The heavier foamed articles have increased strength after loading.

Title: Efficient absorption refrigeration circuit with ejector - using stripped liquor from fractionator at high pressure to drive ejector and operate absorber at higher pressure than fractionator
Inventor: LANGENBACH ROLF DIPL ING
IPC: F25B29/00
Filed: 1978-01-14
Abstract: The refrigeration circuit uses a heated fractionator to drive it. The fractionated NH3 from this passes to a condenser and then on to an evaporator at lower pressure. The weak, stripped soln. from the fractionator is at the high pressure and this is fed to the nozzle of an ejector. The suction side of the ejector is connected to the evaporator. The resulting mixt. enters the absorber which operates at a higher pressure than the evaporator. The resulting soln. is pumped back to the fractionator. Used as a heat pump or refrigerant circuit. Gives improved efficiency and performance coefficient. Also reduces the cooling water usage.
