Title: Combined solar and wind energy power plant - uses electrolysis to produce hydrogen and which is subsequently burnt as fuel in IC engines coupled with turbines or generators
Inventor: BEYER GUSTAV
IPC: F03D80/60
Filed: 1976-11-06
Abstract: The design uses solar and wind energy to produce hydrogen, which then is used to drive generators. The plant consists of wind driven generator units (1), solar energy plates (2), both of which jointly produce the electric energy sufficient for continuously producing hydrogen by electrolysis. The hydrogen is stored in large vessels preferably underground and is then used as a fuel for driving i.c. engines or turbine (7) coupled with generators (11). The removal of excess heat from the surface of the combustion engines or turbines is effected by a cooling fan system (6) driven by the combustion engine. Unlimited energy quantities can be harnessed in this way without the problem of pollution.

Title: Angular error compensation in electronic kilowatt hour meters - comparing current and voltage values with noise signal and converting to binary values
Inventor: VIAENE OMER
IPC: G01R21/133
Filed: 1977-02-09
Abstract: Compensation of angular errors in current and voltage transducers in electronic kilowatt-hour meters is realised by a multiplex measurement value scanning method. Compensation is for residual errors, e.g. those due to the 90 degree pulse shift between current and voltage, and additional errors due to the time lag between voltage and current measurement. The current and voltage values are compared with a noise signal and converted to binary values. The first binary value of a current-voltage pair is fed to a store and the second to a multiplier for product formation. The multiplex frequency is dependent on the current and voltage converter angular errors and the input signal frequency.

Title: Protective layer for semiconductor devices - consists of self-hardening lacquer applied to devices grouped on adhesive tape
Inventor: CHADDA MADAN MOHAN DIPL PHYS
IPC: H01L21/68
Filed: 1977-02-24
Abstract: A protective layer is applied to semiconductor devices prior to storage or to their simultaneous machining, by grouping the semiconductor devices with a certain spacing on a carrier strip coated on one side with an adhesive layer. A self-hardening protective lacquer, e.g. rubber in dispersion or soln. with a small surface tension, is applied between the semiconductor devices to coat their pn-junctions. The protective lacquer foil with the enclosed semiconductors is finally pulled off the carrier strip. A large number of semiconductor devices can be protected economically with a uniform and durable protective coating.

Title: Programmable switch module with stacking facility - has snap action contact operated by adjustable selector discs and common shaft
Inventor: SIGNORELLI NORBERT
IPC: H01H43/10
Filed: 1977-02-28
Abstract: The switch contact module allows a number of switching operations to be obtained by the choice of individual modules which can be mounted on a common drive shaft driven from a timer mechanism. Each module comprises a housing (10) which may be mounted on a standard rail. Each has screw terminals (15a-b) for electrical connections.

Title: Cylinder of rotary IC engine - has shell of different material to restrict thermal movement
Inventor: IMAIZUMI KENICHI
IPC: F02B55/08
Filed: 1977-05-05
Abstract: The engine has a cylinder (1) with an inner face (2) in the shape of a trochoid which forms the boundary of the working space (5). The cylinder is closed at its axial ends by end plates (3, 4) which are held to the cylinder by bolts (7) running through holes (6) axially through the wall of the cylinder (1). The cylinder is made as a light aluminium casting. A shell (2) of a different material is cast into the wall of the cylinder during manufacture. The shell has a smaller coefficient of thermal expansion than the cylinder. It therefore exerts forces which prevent repeated expansion and contraction and thus prevent deformation of the cylinder resulting from such repeated movement.

Title: Bridge laying tank bridge support mechanism - has unit hinged to front of tank with arms swinging or moving forward
Inventor: ILLGNER EBERHARD
IPC: E01D15/127
Filed: 1977-06-08
Abstract: The support unit (3) which can be set up on the ground ahead of the tank in the direction of laying is used for support of a bridge while the laying tank is installing it. The device is hinged to arms (4) mounted at the front end (1) of the tank (2) so as to be able to swing or slide forward.

Title: Electric cable twisting machine - has a store with angled guide rollers to hold strands as windings to increase number of strands
Inventor: FUNKE PETER ING GRAD
IPC: H01B13/02
Filed: 1977-12-29
Abstract: The store unit for twisting strands into an electric cable, with layers of left and right twists, is a carrier body mechanically coupled with the twisting disc arranged to rotate concentrically with the twisting axis. It carries guide rollers which are angled against the twisting axis to store the twisting strands in spiral windings. The twisting disc has a guide to draw the strands from the store. There is a further guide outside the twisting unit, which does not rotate with it, which slides forwards and backwards along the twisting axis to guide all the strands in parallel and together to the store. The design increases the number of strands which can be twisted into an electric cable, and the gap between the twisting direction change-over points gives at least more beaten lengths.

Title: Hydraulic system with common pump and several outlets - has throttle valve on pump inlet controlled by high pressure outlets
Inventor: KOBALD WALTER DIPL-ING
IPC: F15B11/02
Filed: 1978-04-10
Abstract: A constant volume pump draws hydraulic liquid from a container and delivers it to a discharge pipe which branches to two high pressure outlets. Each of these has a control valve on its inlet. There is a multi-position throttle valve on the inlet to the pump. A branch from the pump delivery goes through one section of this valve to a low pressure outlet.
