Title: Open end spinning - in which opened fibre roving is twisted by contact with transverse belt
IPC: D02G3/22
Filed: 1971-09-08
Abstract: A spun yarn is formed by feeding an opened roving of parallel (non)-textured fibres across a pref. endless belt moving in a direction transverse to the advance direction of the roving whereby the roving is twisted by contact with the belt to form a yarn, and pref. the yarn is taken up under tension directly from the belt.

Title: Large floating offshore structure - assembled from two parts built on shore and floated to site
IPC: B63B9/06
Filed: 1973-04-27
Abstract: Large floating structure, e.g. semisubmersible offshore drilling platforms for oil and gas, are assembled in three stages.

Title: Semiconductor diode with improved forward characteristics - has diffusion produced pn-junction with one side impurities connection
IPC: H01L29/861
Filed: 1975-03-28
Abstract: The semiconductor diode has a pn-junction produced by diffusion of impurities in its semiconductor body, whose current carrying surfaces are provided with contacts. The impurities concentration is increased on one side, starting from the pn-junction, forming a flat doping profile generated by impurities diffusion. After the starting gradual increase the concentration rises steeply. Preferably the thickness of the zone with the flat doping profile is such that the space charge zone boundary extends in the zone with the flat doping profile. The overall thickness of the region containing this zone may be smaller by at least 20% from the pn-junction up to the adjacent contact than the spacing between the pn-junction surface from the original semiconductor body surface.
Patent FR-2308979-A1 (FR)
Title: Stabilised voltage regulator generating two DC output voltage levels - uses two channels with comparators to generate error signals for coupled loops
IPC: G05F1/585
Filed: 1975-04-24
Abstract: A two channel stabilised voltage regulator generates two output voltages using cross coupled feedback loops. Two voltage sources (1, 6) generate unregulated outputs that are transmitted over regulating stages (2, 7) to produce outputs (V1, V2). The output voltages are compared (4, 9) with reference settings (E1, E2) to generate correction signals (V1, V2) that are related to the errors (E1 and E2) by gain constants: CV2 =-k2.E1, CV1 =+k1E2. The correction signals are applied to the regulating stages such that: e1=V/1+k1k2, E2=-k2V/1+k1k2. Therefore a change in one direction of the voltage in one channel produces a similar change of opposite sign in the other channel.

Title: Electrolytic formation of spiral groove in bearing - uses external spiral shaped electrode and pulsating current
IPC: F16C33/10
Filed: 1975-10-10
Abstract: A bearing bush (1) with a hole diameter of less than 10mm has a spiral groove which produces a pumping action on the lubricant between shaft and bearing bush. The spiral groove is formed by an electrode with an external spiral groove, placed concentrically inside the bush. An electrolytic fluid is then pumped through the ring gap between bearing bush and electrode so that when electric impulses are passed through the system, the spiral groove is formed by electrolytic erosion. The electrode is a close fit in the bush, and the groove can be of the order of 250mm depth.

Title: Pollution reduction system for two stroke engine - has additional inlet port to admit fresh air to cylinder to form layer above piston
IPC: F02M25/00
Filed: 1976-03-26
Abstract: The two stroke engine has a combustion chamber (1) formed in the cylinder head (2) attached to the cylinder block (3). Air Air which has been drawn into the crankcase through the port (14) is forced into the passage-way (12) by the downward motion of the piston (4). When the piston (4) is at bottom dead centre the air flows into the cylinder through the port (11) whilst the exhaust gases are expelled through the port (9). As the piston moves upwards the ports are closed but a layer of pure air remains above the piston. Air and fuel mixture from the carburettor flows into the duct (15) and through the open poppet valve (5). The discharge to the atmosphere of unburnt fuel is thus avoided.

Title: Axial retainer for ball bearing outer race - has disc with three equally spaced arms bent to fit into keyways in housing
IPC: F16C35/077
Filed: 1976-05-12

The disc has a central bore to clear the shaft and three equally spaced arms (7). The arms are bent at right angles to the plane of the disc (5) to enable them to fit into keyways formed in the bore of the housing (1). The arms are forced outwards from their free position when the bearing (12) is inserted so that the bearing is securely held. At the same time the arms prevent any rotation or axial movement of the bearing outer race. For additional strength the arms may be made with a cambered cross-section.

Title: Protein prepn. from methane by microbiological fermentation - with further microorganism to prevent foam
Inventor: MYERS PHILIP ALBERT
IPC: C12N1/26
Filed: 1976-05-12
Abstract: Protein materials are prepd. from methane by cultivation of an aq. nutrient media in the presence of methane, an oxygen contg. gas, a microorganism (I) using methane and at least one microorganism (II) which can use the foam producing substances formed by the first microorganism. Also the following microorganism strains are novel: Methylococcus capsulatus NCIB 10856, a bacteria strain NCIB 11134, Moraxella NCIB 11135, a strain of Alcaligenes, Agrobacterium or Pseudomonas NCIB 11136, 11137 and 11141; a strain of Alcaligenes or Pseudomonas NCIB 11140. The protein is used and Acinetobacter NCIB 11140. The protein is used as a food source. In a previous process similar to the above, the foam produced has had a harmful effect and anti-foaming agents bath reduce the yield and contaminate the product. The presence of the microorganism which can use the foam producing substances overcomes this difficulty reducing or eliminating the foam.
