Title: Reciprocating piston compressor lubricating system - has oil injected in inlet and separated in pressure vessel for return via cooler
Inventor: STUMP EUGEN
IPC: F04B39/06
Filed: 1976-12-14
Abstract: The reciprocating piston compressor is cooled by injecting oil in the compressor suction line, the oil being subsequently removed from the compressed gas in the pressure vessel connected to the compressor outlet (4) and acting as separator. The separated oil is used again after cooling in an oil cooler (6), which can be by-passed (2) when the compressor is cold. There may be a second oil feed to the intake, directly from the crank case sump. The oil lubricates the compressor valves thus reducing valve wear, in addition to providing piston lubrication. It is claimed that no further cooling of compressed gas is required, cooling being exclusively by air cooling of the oil cooler.

Title: Pleasant-tasting caramelised lactulose - for treatment of constipation, ammonia intoxication of the large intestine, and salmonellosis
Inventor: KERLING JOERG
IPC: A61K31/70
Filed: 1977-04-21
Abstract: Caramelised lactulose is new and consists of lactulose, adjuvants, by-prods. of carmaelisation, and water. It has the same uses as the unaltered disaccharide. It is useful in the treatment of chronic constipation, in the treatment and prophylaxis of ammonia intoxication of the large intestine, esp. in liver cirrhosis with portal hypertension, and in modifying intestinal flora for treating salmonellosis. While being equiactive with crystalline lactulose, caramelised lactulose is a pleasant-tasting material similar to caramelised sucrose and can be administered e.g. in the the form of toffees. The caramelisation process is easier to carry out than the crystallisation of lactulose. In an example, aqueous 50% lactulose is boiled with animal or vegetable fat up to incipient caramelisation, then mixed with milk and further boiled to give a toffee which is poured into bonbon moulds and cooled.

Title: Thin film FET prodn. using tantalum pent:oxide as gate oxide - by anodic oxidn. of doped tantalum gate electrode giving high transconductance
Inventor: LUEDER ERNST PROF DR ING
IPC: H01L21/34
Filed: 1978-05-10
Abstract: In the prodn. of thin film FETs, Ta2O5 is used as gate oxide. This is produced by anodic oxidn. of the gate electrode of doped Ta produced by photolithography and etching before application of the semiconductor film. The high dielectric constant of Ta2O5 compared with Al2 O3 or Y2O3 leads to high charge carrier inductor in the semiconductor channel and hence to a higher transconductance of the transistor. Also, the dielectric is stable for over 2 h at over 300 degrees C, which is decisive in mfr. The individual process stages can be optimised, since intermediate tests are possible. Used in mfr. by photolithography and etching, the surface is cleaned, before application of the semiconductor, in the same vacuum stage by etching with ions or uncharged particles. Very small channel lengths can be formed by the thickness of the semiconductor film.
