Title: Fin driven inflatable watercraft - has central axial slot for fin operating arm and saddle for footrests positioned to increase lateral stability on excess roll
Inventor: VILLINGER FRANZ DIPL ING
IPC: B63B7/08
Filed: 1976-10-21
Abstract: The fin propelled inflatable watercraft has a hull (1) in the shape of a solid of revolution, with a central axial slot. Into this fits a rigid box structure (2) through which passes the flexible fin (6) operating arm (5). The arm has a transverse pivot (8) and a handle (7) projecting above the hull. Fitted over the hull, around the box, is a saddle (3) carrying radial footrests (4) high enough above the loaded waterline (W) not to be immersed by the 15-20 deg. roll needed for propulsion. Should immersion nevertheless occur, the footrests are shaped to increase the craft's lateral stability.

Title: Exhaust feedback control for fuel injector pump - has rack with permanent magnet regulator plunger to control follow-up piston
Inventor: NOLTE ALBERT
IPC: F02B37/18
Filed: 1976-10-26
Abstract: The pump regulator housing has a cylindrical bore containing a follow up piston. The piston is loaded at one end by a spring pressure against the fuel pump body. The opposite end of the piston is subject to a pressure medium via a restricted feed pipe. The follow up piston has an axial bore containing a regulator plunger which is an axially movable permanent magnet. The latter regulates pressure medium channel running from the front to the rear of the follow up piston. The magnet engages the free spherical end of the pump control rack to form a restricted gap which varies with the pump rack movement. Spring pressure moves the piston to a new position to actuate a corrugated tube which regulates the exhaust feed back valve.

Title: Leather fibre fabrics prodn. by wet processing - using heat coagulable binder to assist dewatering on the drainage wire
Inventor: WENTZEL HERMANN
IPC: C08L89/06
Filed: 1977-01-07
Abstract: In the prodn. of leather fabrics from leather fibres, binders, and opt. other additives, fibres such as cellulose, cotton linters, etc., heat-sensitised binders are used in emulsion or dispersion form and the binder is coagulated by heating just before entry into the dewatering machine. Process allows leather fabrics to be made with wet conversion of the leather (scrap) into fibres, which gives better fibre structure than dry conversion processes. The use of heat-sensitised binders, which can be coagulated by the introduction of heat just before dewatering, overcomes previous difficulties encountered with systems of this type, in which the swollen leather fibres and the binder caused blockage of the draining wire in the dewatering stage, thus giving very slow rates of prodn. Coagulation of the binder before drainage overcomes this problem and allows increased rates of prodn. to be achieved.

Title: Transformer core winder producing coil groups - winds turns in cyclic symmetric pattern to reduce radial dimension
Inventor: PESTRJAEVA GEB BULATOVA LJUDMI
IPC: H01F41/086

IPC: G01R15/08
Filed: 1977-08-02
Abstract: A mutlirange meter has two input terminals (11) one of which is connected to earth and the other of which is connected to a potential divider (20). Tappings on the potential divider are selected by a range selector switch (12) to provide desired full scale deflection for a given input voltage level.
