Patent DE-2916058-A1 (DE)
Inventor: HUBER JOHANN
IPC: A61L2/07
Filed: 1979-04-20
Abstract: After a steam sterilisation, a sterilisation chamber (1) contains moist air which passes through a circulation, partially located outside the chamber, with the process steps mentioned below:   a) extraction of the moist air by a blower (10) into a condenser (8),     b) cooling of the moist air in the condenser (8), c) discharge of the separated condensate into a condensate separator (11),   d) heating of the demoistened air in an air heater (9), and   e) blowing of the heated air back into the chamber (1).   By treating the air outside the chamber it is effectively and quickly demoistened, so that it can absorb further moisture. The method can be employed under any pressure conditions in the chamber. <IMAGE>

Title: Combined heat and power generator - has water in power cylinder evaporated by indirect heat transfer for higher efficiency
Inventor: RABIEN PETER
IPC: F01K21/02
Filed: 1980-01-16
Abstract: The engine has a piston (2) reciprocating in a cylinder (1). The cylinder space above the piston contains water (4). A condenser (7) floats in the water. Its upper part consists of finely divided heat exchange and storage material and its lower part is a compressible bellows (8). A heat transfer block (6) projects through the top of the cylinder.

Title: Horizontal coke oven charging system - involves introducing inert gas into coke oven gases to dilute them to safe concn.
Inventor: SILKE ADOLF N
IPC: C10B31/04
Filed: 1980-07-29
Abstract: Method is described for charging a coke oven battery whose coking chambers each have at least three charging holes. Coal is charged into a coking chamber through its extreme charging holes whilst simultaneously withdrawing gases through a middle charging hole. Subsequently, the charging is completed by charging and into the chamber through the middle charging hole whilst simultaneously withdrawing gases through the same hole. The gases are withdrawn are diluted with inert gaseous diluent constituting 15 to 20% of the total amt. of the gases withdrawn. The method permits the safety of the charging to be improved by withdrawing the coke-oven gases from the charging zone and simultaneously introducing a gas inert to the coke-oven gas in an amt. sufficient to dilute the latter to a safe concn.
Patent DE-3033565-A1 (DE)
Title: Restoring square pulse from degraded pulse - using cross-over points of degraded pulse and slightly delayed and reduced pulse trigger comparator
Inventor: ZIMMERL RUDOLF ING
IPC: G01R29/02
Filed: 1980-09-05
Abstract: A degraded pulse is restored into a square pulse irrespective of voltage levels by feeding it to one input of a comparator. It also passes through a delay element formed by a low-pass filter, is reduced by a potential divider and then goes to the other input of the comparator. The comparator switches on at the cross-over points (A,B) of the degraded pulse (Ust) and the slightly delayed and reduced pulse (Uv). The low-pass filter is formed by a simple R-C network. Fluctuations of the comparator are avoided by applying some feedback, thus resulting in a slight hysteresis effect.
