Title: Ambient thermal energy extracting generator - uses compressed ambient gas to heat directly heating elements and to flow through heat exchanger
Inventor: WEISPFENNING HELMUT
IPC: F03G7/04
Filed: 1974-02-06
Abstract: The thermal energy generating system is intended for use with the atmosphere, exhaust gases, liquids, solids or from the interior of the earth. Atmospheric air or another gas flows through a suction pipe to a single or multistage air pressure generator. The heater elements yield a proportion of the heat energy, with teh remainder of the heat being processed in the heat exchanger and reaching the suction pipe. The air pressure drives an air compressor motor so that the motor unit for the air pressure generator is used as an auxiliary motor. A closed circuit may be added to the thermal installation, in which an injection pump forces water or another liquid into the pre-evaporator. The steam may flow through a superheater driving a turbine providing the generator drive. Inside the heat exchanger the steam may condense the surplus heat during this process being transferred to the suction pipe.

Title: Projection photolithographic process for producing LSI circuits - involves step and repeat exposure for minimum distortion
Inventor: FELDMAN MARTIN
IPC: G03F7/20
Filed: 1974-03-21
Abstract: The master and prepared sample are held in a special equipment which exposes only part of the sample at any one time. After exposure master and sample are moved in a step and repeat manner so that all parts of the sample are exposed. The process eliminates the field distortion at the edges of the projection process and enables the fine detail required for LSI circuits to be accurately reproduced. The optic system has a beam splitter so that part of the beam is taken to a monitor which ensures that every part of the sample is exposed with the same intensity. The process enables the advantages of projection exposure to be applied to high resolution repeated patterns.

Title: Wire loom shuttle charging system - has sliding bolt to allow weft insertion to be clamped by bolt moving mass on shuttle acceleration
Inventor: SCHUSTER KARL ULRICH
IPC: D03D41/00
Filed: 1974-09-27
Abstract: A weft insertion apparatus is claimed for a loom developing fabric materials from metal or plastic wires, with a slide bolt mounted in the shuttle in the direction of travel to operate the weft grip mechanism by its moving mass on the acceleration of the shuttle. The weft is inserted into the shuttle through a channel which is exposed by radial play when the shuttle arrives at the feed station as braking forces act on a sleeve so that the weft can pass into the shuttle and range into the gripping mechanism before the shuttle has come to rest. The system ensures that the weft is grasped sufficiently firmly to carry it across the loom, but without distorting or marking it so that apparent flaws are not woven into the material.

Title: Albumen and baking ferments from a single fermentation vessel - in which pH electrode regulates input of nitrogen source and substrate
Inventor: MOEBUS OTTO DR
IPC: C12N1/16
Filed: 1975-01-07
Abstract: A continuous process for the prodn. of albumen and baking ferments in tandem arranged aerating fermenters, uses a mixed culture of lactic acid bacteria and ferments assimilating lactic acid. Ammonium sulphate or urea can be used as the source of nitrogen, thus making only one fermenter necessary. The ammonium sulphate or urea necessary for the growth of the culture is used first of all for the autolysis of a portion of the yield of ferment. The finished autolysate is then introduced into the skim milk as the only additive. The hydrogen ion concn. in the fermenter is automatically adjusted by the feeding in of skim milk mixed with the autolysate of the ferment, via an electronic control, and a valve, by means of a pH electrode (2). After the enzymes for breaking down the albumen have been fed in, in addn, the structural elements of the milk proteins are assimilated by the ferments, so that no further operation for dealing with the milk proteins is necessary.
