Patent DE-3140326-A1 (DE)
Title: Pneumatic working element for central locking systems
Inventor: ANDRES RUDOLF
IPC: E05B65/38
Filed: 1981-10-10
Abstract: The invention relates to a pneumatic working element for central locking systems of vehicles. The cycle of movement of the linear working element can be reversed by alternating pressure load. It has only a single working chamber and is moved by overpressure into one end position and by underpressure into the other, specifically into the locking end position. Arranged in the flow line are two functionally parallel non-return valves which block oppositely to one another. The non-return valve open during unlocking is so designed that for the type of pressure having a locking effect, namely underpressure, it blocks automatically both when loaded from the flow line and when subjected to pressure from the direction of the working chamber. This affords a pneumatic limit safeguard for the locking end position and consequently protection against unauthorised displacement of the pneumatic working element.

Patent DE-3231764-A1 (DE)
Title: Wing rig
Inventor: DUSCHEK HORST
IPC: B63B35/79
Filed: 1982-08-26
Abstract: A novel self-supporting wing rig is described which in one version essentially consists of a slightly negatively swept-back main wing as well as a secondary wing attached in an upright position to the longitudinal centre plane of the main wing. In one embodiment, main and secondary wings are formed from sails which are stiffened by aerodynamically preformed battens and are stretched between a front bar, a profiled end bar and two edge bars or a mast and a centre boom. When the sail is set against the wind, the self-supporting rig stabilises itself in its transverse axis on account of a transverse rudder position. The vertically directed secondary wing supplies propulsion forces for driving, for example, a windsurfing board; the main wing develops drive forces for compensating for the weight of the appliance and the user. Wave jumping in particular can be facilitated during windsurfing by means of this wing rig.

Patent DE-3247392-A1 (DE)
Title: Heat exchanger
Inventor: HAGE MANFRED DR ING
IPC: F25B39/04
Filed: 1982-12-22
Abstract: The invention relates to a heat exchanger (1), in particular condenser, for the coolant in heat pumps, which has pipe coils (7 to 14) for the water throughput which are connected parallel to one another between centrally arranged inlet and outlet in a cylindrical container (2) which is closed off with a cover (4) and a bottom (3), each pipe coil (7 to 14) having its own inlet pipe (7' to 14') and its own outlet pipe (7'' to 14'') which in each case is guided out of the container (2) through the bottom (3) or through the cover (4) respectively, and which has a pressure pipe (16) as well as a suction pipe (17) for the coolant, according to Patent ... (Patent Application P 3230306.8-13). In development of the subject of the main patent (Patent Application P 3230306.8-13), it is proposed that the inlet pipes (7' to 14') and the outlet pipes (7'' to 14'') are in each case collected together in the same manner to form at least two groups, consisting of in each case one or more of the inlet pipes (7' to 14') or of the outlet pipes (7'' to 14''), which open into in each case mutually separate inlet ducts (5a, 5b) or outlet ducts (6a, 6b).

Patent DE-3302448-A1 (DE)
Title: Elastomer hydraulic accumulator
Inventor: MENKHOFF KARLHEINZ
IPC: F15B1/08
Filed: 1983-01-26
Abstract: The elastomer hydraulic accumulator has, as spring element, a viscous compressible elastomer. In contrast, the previously known hydraulic accumulators have either a spring, a weight or nitrogen as the spring element. The compressible elastomer has considerable advantages over all previously known spring elements. The compressibility, and consequently the spring force, remains virtually unchanged from -40 DEG C to +80 DEG C. Any desired spring rate can be achieved by changing the volume of the elastomer. Due to the possibility of high prestressing pressures of up to 1000 bar and final pressures of up to more than 2000 bar, the actual spring element remains relatively small. The elastomer hydraulic accumulator operates with a shouldered piston. When the pressure is intensified, this piston is subjected to the high pressure of the elastomer on the small piston area and to the pressure fluid of the hydraulic system on the large piston area.

Title: Method for the production of multiple mower knife sections and cutting knives
Inventor: LINDEMANN FRIEDRICH
IPC: B21K11/00
Filed: 1983-03-04
Abstract: In the production of multiple mower knife sections (1) and cutting knives for hedge cutters and for cutting weeds and the like, where a plurality of approximately trapezoidal or triangular cutting parts (2) adjoin one another, there is the difficulty of producing the inner cutting surfaces (7). Hitherto, these cutting surfaces have been produced by form grinding or milling or, alternatively, by bending the entire cutting region round and then grinding from below.   However, since these methods are very expensive with regard to the equipment required, its maintenance and the work time involved and since, in addition, there are deficiencies in the quality of the knives, such as high decarburisation, breaking of the grain of the material, in the region of the cutting edges, the invention proposes to produce the cutting surfaces (7) by extrusion and then to grind flat the underside, if required. <IMAGE>

Title: Wiper device for motor vehicle windows
Inventor: BRUEMMER DIETMAR
IPC: B60S1/34
Filed: 1983-04-21
Abstract: A device is proposed which serves to wipe motor vehicle windows. The wiper device comprises a wiper shaft which is preferably driven in pendular fashion and to which part of a wiper arm which is divided transversely to its longitudinal extent is attached. At the free end of the other part of the wiper arm which part is connected to the first part of the wiper arm in an articulated fashion, a wiper element is arranged which is spring loaded against the window to be wiped. The axis of the joint between the two parts of the wiper arm is located essentially in a plane parallel to the plane of the pendular motion of the wiper arm. An actuation element which can be displaced in a longitudinal bore of the wiper shaft influences the spring loading of the wiper element against the window. One end of a pretensioned spring is attached to the second part of the wiper arm and its other end is operatively connected to the actuation element. By displacing the actuation element in the wiper shaft, the contact pressure of the wiper element on the window can be changed.
