Title: Reaction propulsion system for ships - has thermal turbine engines using external pods submerged or above water
Inventor: VESTER GERHARD
IPC: B63H21/06
Filed: 1975-09-08
Abstract: The reaction propulsion system for ships with thermal turbine engines is suitable for a wide variety of fuels and can use the heat energy from a nuclear fuel plant. It comprises power pods external to the hull containing an axial duct protected at each any by a filter. An annular combustion chamber surrounds the middle portion of this duct embodies injection mixing arrangements for the combustibles. An exhaust duct from the top may be used for discharge or recycling. Pods may be fitted either or below the waterline. Water or air entering the duct first passes through a compressor, driven by a turbine located in the outlet section. It then enters the high temp. section where it is caused to increase greatly in vol.

Title: Filter plate for sewage sludge dewatering press - has spacer lugs with clamp rings for filter cloth
Inventor: BUSSE OSWALD DR ING
IPC: B01D25/176
Filed: 1975-09-19
Abstract: The plate has bosses which protrude from the filter cloth plane to a plane flush with the plate rim to act as spacer and support for the next filter plate. The bosses are shaped like truncated cones and the filter cloth which extends only up the cone walls is retained by a clamp ring, held by a setscrew and washer. This simplifies the machining of the filter plate which can be machined simultaneously on the rim and on the boss. The filter cloth is fixed securely without stressing it unduly near the bosses.

Title: Rocking melting furnace for metals - melts charge dropping from shaft by heat shock and hot wall contact
IPC: F27B3/06
Filed: 1975-11-28
Abstract: A metal melting furnace consists of a horizontal drum which can be reciprocated and receives the charge at one inclined end from a vertical shaft. A burner injects a flame at high temp. and velocity at that end so that the charge is molten by a heat shock and flows into the heating chamber. Contact with the hot walls increases the melting rate still further. Such a furnace requires a minimum of heating chamber area and of overall furnace dimensions. Independent of the type of material, a high throughput is achieved by the combination of heat shock with reciprocating rotation.

Title: Mfr. of extrudates, e.g. pipes, cable sheathings and coatings - by conveying them along an inclined or catenary-curve path whilst heating to crosslink them
Inventor: FLIEHS HEIRNICH ING GRAD
IPC: B29C48/09
Filed: 1976-02-02
Abstract: Mfr. of extrudates, such as sheatings and coatings for power cables, or pipes and tubes, comprises subjecting the thermoplastics or elastomeric material, after shaping to thermal treatment.

Title: Sludge evacuating system for sewage plant - has suction box float sinking and rising alternately to clear filters
Inventor: WAGNER GEORG ING GRAD
IPC: B01D21/24
Filed: 1976-05-25
Abstract: A sludge evacuating plant consisting of a long tank, has that part of the vessel into which the suspension sludge is fed, sepd. from the rest by partitions incorporating filters. In the sludge water compartment, there is a suction box joined by a pipe to a float, which is connected in turn by a flexible pressure hose and values to suction and to a source of compressed air. The valves in the lines to suction and to the compressor are solenoid controlled, or for the compressed air line, a valve of the type which closes automatically when the flow through it is excessive, may be used. On the underside of the suction box, there are openings through which water can be sucked in or air blown out, so that the float can be made to fall and rise alternately. The arrangement is cheap to mfr. and efficient and reliable in operation, in contrast to the conventional perforated drum with a scraper and suction box. With only one suction pump and a small compressor a range of tanks can be cleaned continuously.

Title: Power pod for launching model glider - has parachute deployed after separation of pod from adaptor element on underside of glider fuselage
Inventor: SCHROEDER LLOYD ALBERT
IPC: A63H27/24
Filed: 1976-09-21
Abstract: A power pod is releasably coupled with a model aircraft such as a model glider plane, to initially power the aircraft into flight and to thereafter separate from the aircraft. An adaptor element is affixed to the underside of the model aircraft fuselage, and the power pod is releasably coupled with the adaptor. The power pod remains coupled with the adaptor to power the model aircraft as the power pod is providing a forward thrust. In one embodiment, the power pod separates from the adaptor when operation of the power pod ceases; in another embodiment, the power pod remains coupled with the adaptor after operation of the power pod ceases, and separates upon command of a remote control radio signal. Upon separation a parachute stored within the pod is deployed by means of a rip cord connected at one end to the model aircraft. The rip cord includes a replaceable breakable link which breaks as the pod and the deployed parachute fall away from the model aircraft.
