Title: Braking system for vehicle or machine - has fly wheel energy reservoir to store and return braking energy
Inventor: LENSING JOERG DIPL ING
IPC: F16D61/00
Filed: 1978-09-27
Abstract: A gear drive connects the vehicle drive shaft with a flywheel. When the engine output torque falls to zero a clutch disconnects it from the shaft and a clutch connects the gear to the shaft. The kinetic energy of the vehicle is then absorbed by the flywheel which brakes the vehicle. The braking effect is varied by variation of the gear ratio. When the drive shaft ceases to rotate, a clutch disconnects the flywheel from the gear drive. The drive is reconnected when the vehicle is to be restarted so that the energy stored in the flywheel can be returned to the shaft.

Patent DE-2852897-A1 (DE)
Title: Heater for liquids or gases - has metal sleeve which is made of resistance material and carries heating current from transformer
Inventor: PAULS ERHARD
IPC: H05B3/00
Filed: 1978-12-07
Abstract: The heater, especially for vaporising liquids such as propane and butane has a heated tubular sleeve through which the medium being heated flows. The metal sleeve is constructed as an ohmic resistance and connected directly to both poles of a voltage source. The voltage source is formed by the ends of the secondary winding of a transformer whose primary receives an ac voltage. Alternatively, the metal sleeve forms the short-circuited secondary winding of a transformer whose primary receives an ac voltage. The advantage lies in high efficiency, fast response little maintenance, long life and low fabrication costs.

Patent DE-2933358-A1 (DE)
Title: Reducing ships or vehicles boundary flow resistance - by providing surface with contour causing turbulence in boundary layer at expected relative velocity
Inventor: MONDRE HEINZ
IPC: B62D35/00
Filed: 1979-08-17
Abstract: The arrangement is intended for reducing the flow resistance generated at the boundary of an object exposed to fluid flow. This is achieved by providing the object with a contoured surface, this contour being adapted to the expected relative flow velocity and to the boundary layer which would occur on a smooth surface at that velocity. This adaptation should be such that the contour produces turbulence in the boundary layer, which reduces frictional resistance. The contours may be produced on foil subsequently applied to the surface or by applying a setting material to the surface and then expose it to fluid flow which automatically produces the required contour.

Title: Prepn. of fish fillets for storage - by squeezing them into a skin to form a sausage which is subsequently cut and frozen
Inventor: CHRISTENSEN BOERGE
IPC: B65B25/06
Filed: 1979-09-13

Title: Solar energy utilisation - by photosynthetic plant growth for food and biomass based energy generation
Inventor: KRAUS HANS ING GRAD
IPC: A23K10/30
Filed: 1979-10-15
Abstract: Solar energy is utilised by converting it through photosynthesis into organic plant matter. The prim. yield of the plant substance is partly used as food for man and cattle and partly mixed with the sec. yield in the shape of human and animal excreta. The mixt. is converted to methane or ethyl alcohol by an anaerobic fermentation of the mesophilic or thermophilic type. The digested sludge produced is dried, granulated and applied as nitrogenous fertiliser to the fields to close the biological cycle. This saves other types of not reclaimable energy (coal, oil) and replaces them by inexhaustible supplies of solar energy.

Title: Anti brake lock hydraulic valve - has piston moved by brake pressure against dished spring and electronic sensor-operated positioner cam
Inventor: ROSANOWSKI OSWALD JOSEF
IPC: B60T8/42
Filed: 1980-01-17
Abstract: The anti-brake lock system is intended for a hydraulic brake circuit and comprises a dished spring-loaded (13) valve piston (9) with annular groove (10) controlling the connection (at 7) from the master cylinder to (at 8) a brake cylinder. The brake cylinder pressure also connects (via 2) to the top of the piston and acts against the spring to interrupt the brake pressure. A sensor responds to wheel speed, acceleration and deceleration and activates an electronic circuit controlling a positioner provided with a cam (16) rotatable by the positioner to lift the piston. The arrangement is such that, when the wheel blocks, the brake pressure is first interrupted, then released (via 8,2) and re-applied.
