Patent DE-3150900-A1 (DE)
Title: Method for converting heat energy into mechanical energy
Inventor: SALDERN RUEDIGER VON
IPC: F01K5/00
Filed: 1981-12-22
Abstract: The invention relates to a method for converting heat energy into mechanical energy, in which a fluid is heated within a closed circulation system, in the process is raised to a high pressure, and is allowed to expand, performing work in the process. If the condensation is carried out against cooling water, the choice of the type of fluid is restricted since, for example, it is not possible to use a fluid, the condensation temperature of which is below the given temperature of the cooling water. A similar statement applies to the evaporation of the fluid. In order to make possible the use of a multiplicity of fluids, the invention proposes that the expanded fluid be taken up by a sorbent and that fluid-laden sorbent be regenerated, the supply of further fluid to the sorbent during the regeneration of desorbed fluid being fed under high pressure to the work-performing expansion again.

Patent DE-3208799-A1 (DE)
Title: Liquid-manure sprinkler
Inventor: SCHANZ FRIEDRICH
IPC: A01C23/00
Filed: 1982-03-11
Abstract: The liquid-manure sprinkler which is connected to the delivery line of a tractor-drawn liquid-manure tanker and which is pivotable about a vertical axis by means of a driving device is driven by a separate hydraulic motor or electric motor, from which a supply line is guided to the standardised energy source, namely to the hydraulic or electrical system of the tractor.

Patent DE-3232061-A1 (DE)
Title: Device and process for recycling waste rubber
Inventor: FICKER STEFAN ING GRAD
IPC: B29B17/02
Filed: 1982-08-28
Abstract: The steel component of steel-containing waste rubber pieces such as steel-carcass tyres is separated as a precursor for a regeneration or other recycling of the waste rubber to be connected downstream in that the waste rubber pieces, which are precomminuted to about the size of the palm of a hand, are rolled over on a corrugated or toothed pressure plate of high hardness (450-600 VH) with large pressure rolls (0.4-2 m) under high pressure (5-500 tonnes). The wire inserts are thus physically detached from the composite with the rubber and separated from this. At the same time the tyre pieces are delaminated and the rubber granulated, this process being favourable for the downstream recycling processes, e.g. regeneration. Prior heating of the waste rubber, e.g. to 100-150 DEG C, is advantageous. In addition it is useful to increase the thickness of the pressure plate in the direction of rolling of the pressure roll and to reduce the depth of the corrugation in the same direction.

Title: Whistle body for whistling kettles
Inventor: THURLOW HEIDA
IPC: A47J27/212
Filed: 1982-11-12
Abstract: Known whistle bodies must, for the most part, be removed and replaced again when the whistling kettle is being used, and in particular there is the risk of injuries caused by the outflowing steam and on the heated whistle body. To avoid these disadvantages, the whistle body according to the invention possesses a fastening part which can be attached firmly onto the pouring spout of the kettle and which is equipped with a bearing for a pivotable actuating lever on which a cover having a built-in whistle is arranged, so that by means of the actuating lever the cover can be pivoted in front of the outflow orifice of the fastening part and pivoted away upwards, and the actuating lever has a U-shaped and thin-walled metallic cross-sectional profile which is open on its underside facing the kettle and into which a plastic body filling the cross-section is inserted, so that the actuating lever cannot become heated and can be operated without the risk of injury.

Title: Manually operated rope-tackle lifting or warping device
Inventor: KOSTURIK VIKTOR
IPC: B66D5/06
Filed: 1982-12-15
Abstract: The invention comprises a portable, manually operated rope-tackle lifting or warping device with a rope drum (13) and a double-ratchet pivoted-lever drive, which can be changed over under load to "pulling" or "easing", and a friction load-pressure brake. Devices of this type are used in industry, trade, agriculture and forestry, boat operation and fishing for lifting, pulling, clamping and similar activities and also serve, for example, as mobile assembly aids, preferably in open-line construction. Known rope-tackle devices of the general type of construction mentioned at the beginning have a friction-disc load-pressure brake and consequently satisfy the relevant safety regulations. On account of the frequent use of such rope-tackle devices as assembly aids, the development tendency in the special field is directed towards designing these devices to be even smaller, more manageable and lighter. This has already been achieved, but the known lighter devices do not satisfy the safety regulations due to the lack of a load-pressure brake. The object of the invention is to provide a rope-tackle device which, while meeting all requirements of the safety regulations, is nevertheless smaller, more manageable and lighter than the known devices mentioned at the beginning. This is achieved according to the invention by a helical-spring friction brake (9, 12) being used as the load-pressure brake and by the pivoted-lever ratchet drive (2, 13a, 15, 16, 16c, 17) being simplified.

IPC: B62D35/00
Filed: 1982-12-24
Abstract: The invention relates to pivotable intermediate-space covers which predominantly cover the sides of the free space between lorry body and trailer body in such a manner that they form approximately a continuous surface with the side surfaces of the lorry and trailer bodies. The intermediate-space covers are mounted pivotably on the end of the lorry body and on cornering are caused by the bending movement of the road train to be pivoted in a positively controlled manner around their joint points in such a manner that they, on the one hand, can be detached from the trailer leading surface, largely adapt themselves to the curve followed by the train, and that, on the other hand, they are prevented from jamming between trailer and lorry body.
Patent DE-3300992-A1 (DE)
Title: Device for the generation of a heated aerosol, especially a medicinal aerosol
Inventor: BALAGNY HEINZ-GEORG
IPC: A61M16/10
Filed: 1983-01-14
Abstract: A device for the generation of a heated aerosol for inhalation purposes can be created with a better and simpler construction method in that an electrical heating element is attached to the outside of the substance container provided in the aerosol generator, the electrical current source of which heating element is controlled so as to achieve a virtually constant operating temperature which should be between about 80 DEG C and about 100 DEG C, preferably about 100 DEG C. This can be achieved most simply by using an electrical semiconductor or PTC resistor as the electrical heating element, on which a virtually constant operating temperature is set by selection of the operating voltage at an inflow time of, for example, 5 minutes. Other ways of control which can be used instead or in addition are temperature controls with temperature sensors in the substance container and/or the aerosol outlet.

Patent DE-3322068-A1 (DE)
Title: Control device for the alternative connection of the intake and pressure connections of a compressor to the connection of a storage chamber
Inventor: STREICHER MAX
IPC: F16K11/085
Filed: 1983-06-18
Abstract: A pressure duct (2) and an opposing intake duct (3), the pipe duct (4) to a storage boiler and the opposing duct (5) to the atmosphere are led off outwards at angular intervals of 90 DEG  from a rotationally symmetrical slide-valve housing (1). A partition wall (7), which divides off the connection chambers (10, 11) and connects by way of an opening (8) closable by means of a valve flap (9), projects at right angles from one axial slide-valve wall (6). The valve flap closes under its own weight, by spring force or due to a flow (15). It is normally swivelled into the open position by a flow (16) from (2) to (4). If, when switching over to pressure operation, the rotary slide valve is swivelled 90 DEG  clockwise, the valve flap (9) closes under its own weight or spring loading and can be opened by a flow from (4) to (3). In the operating position shown, the flap/non-return valve temporarily closes in the event of pressure fluctuations and continues to store the pressure energy introduced up to that time. In the filling process, the intervening closure of the non-return valve causes increasing throttling and prevents any foaming of the filled medium, which permits a reduction of the gas fraction and a greater degree of filling. <IMAGE>

Title: Process for eliminating leaks in hollow fibres in a dialyser
Inventor: BRETHAUER KURT DIPL ING
IPC: B01D65/10
Filed: 1983-09-12
Abstract: The invention relates to a process for eliminating leaks in hollow fibres in a dialyser which is used for separating substances in fluids, especially in artificial kidneys. The aim of the invention is to eliminate leaks without special steps and additional materials being necessary beforehand to define them, i.e. localise them. This aim is achieved by introducing the synthetic resin which combines the hollow fibres at their ends to form heads through the dialysate inlet and outlet connectors of the dialyser housing with a centrifugal force between 90 N and 150 N and at a temperature between 333 DEG  K and 343 DEG  K into the hollow fibres which are open at the front.
Patent DE-3332822-A1 (DE)
Title: Solenoid valve with inflexible valve seal
Inventor: WEISS FRIEDRICH DIPL ING
IPC: F16K31/06
Filed: 1983-09-12
Abstract: The invention proposes a solenoid valve with an inflexible valve seal for fuel injection systems, in which the moving valve member interacts via an armature which, although independent, is connected to the said valve member and through which the magnetic force lines of, on the one hand, a permanent magnet and, on the other hand, an electromagnet can flow. While the permanent magnet pulls the armature and hence the valve member in the closing direction, the force of the permanent magnet is reduced or increased by the electromagnet depending on the direction of the electric current. There is virtually complete freedom of choice in the design of the magnets and of the valve. Viscosity-independent metering is achieved by means of an orifice restrictor arranged in the fuel duct upstream of the valve seat. <IMAGE>
