Patent DE-3143936-A1 (DE)
Title: Wind power installation
IPC: F03D3/06
Filed: 1981-11-05
Abstract: The wind power installation has a wind wheel operating in a horizontal position: carrying frames (6) for meshes arranged in at least one horizontal plane radially to the shaft and symmetrically distributed in a vertical manner are fixed to a vertical shaft (3). Each carrying frame (6) is formed from a carrying arm (6a) radially braced from the shaft (3) and at least one frame lattice (6b) fixed vertically on the carrying arm, one side of which lattice is fitted with at least one of the meshes (7). When the wind strikes the front side (7a), of the mesh, remote from the carrying frame, the mesh imparts a torque to the shaft (3) proportional to its area; when the wind strikes its rear side (7b), the mesh (7) imparts an almost zero torque to the shaft (3). <IMAGE>

Title: Four-legged table, whose table legs are attached to frames
Inventor: HESS EUGEN
IPC: A47B3/06
Filed: 1981-11-24
Abstract: A table which can be made up of elements of a construction kit which can be collapsed in a space-saving manner comprises table frame elements, which can be fixed to a table top and comprise in each case a partial frame and a table leg attached thereto, and reinforcing frames which can be fixed to these table frame elements, extend in each case between two table legs, running at the height of the partial frames, and can be fixed thereto or to the table legs with the aid of clamping anchors. These clamping anchors comprise threaded sleeves which pass through the partial frames and into which angled threaded bolts can be screwed. Cap nuts, which are supported on the outer faces of the reinforcing frames, can be brought into engagement with the free threaded portions of the threaded bolts of the anchor members, which can be inserted in transverse bores of the reinforcing frames. By tightening these cap nuts, the reinforcing frames can be pressed with their chamfered end faces firmly against the table legs so that an inherently sturdy and stable table frame is achieved. Depending on the dimensioning of its components, the table is suitable for all common applications.
Patent DE-3202043-A1 (DE)
Title: Relay, especially a printed-circuit board relay
Inventor: STRACK HOLGER ING GRAD
IPC: H01H50/04
Filed: 1982-01-23
Abstract: The relay has a coil with an iron core formed by pole plates and has at least one contact set with springs which are accommodated in a relay housing consisting of an upper and a lower housing part. The two housing parts have bearings and counter-bearings at least for the pole plates and the springs of the contact set, which hold the pole plates and the springs in a positively locking manner such that they cannot move. This ensures simple assembly of the pole plates and of the springs. Initially, they can be inserted into the bearings in the lower housing part, in which they are already held sufficiently safely against movement. When the upper housing part is fitted on, the pole plates and the springs are then held and secured in a positively locking manner via the counter-bearings provided on this housing part. The upper housing part is used as a hold-down device which secures the parts of the relay to be held in their installation position. The position fixing and holding for the components is distributed between the two housing parts.

Title: Drive device for motor-vehicle window lifters
Inventor: BOEHM HORST DIPL ING
IPC: E05F11/50
Filed: 1982-02-04
Abstract: In a drive device for motor-vehicle window lifters, consisting of a housing (1, 2), of a drive shaft (5) mounted therein and of a driving pinion (8) which engages with the window lifter and which, after a limited idle rotation, is connected non-positively to the drive shaft, there is a ratchet brake which causes no frictional forces during rotations of the actuating crank after the idle rotation has been executed. The ratchet brake consists essentially of a sleeve (14), which is mounted on the drive shaft so as to be axially displaceable and rotatable to a limited extent and is coupled to the driving pinion and which has rolling bodies (25) inserted in clamping recesses (24) in an outer circumferential surface (23) and cooperating with a conical housing wall (22). <IMAGE>

Title: Circuit arrangement for switching a remote-controlled television receiving set on and off
Inventor: KRAUS HEINZ DIPL ING
IPC: H04N5/63
Filed: 1982-02-19
Abstract: A circuit arrangement for switching a remote-controlled television receiving set with a switched-mode power supply for mains isolation on and off is known in which the power supply of the remote-control receiver is ensured via a tap on the secondary windings of the transformer of the switched-mode power supply, in standby mode. To allow the remaining operating voltages to collapse, a high load is connected during standby mode. Due to the oscillatory characteristics of the switched-mode power supply, the necessary supply voltage is only present at the tap for the supply to the remote-control receiver. To switch the set off without load in standby mode, the operating voltages of the receiver circuits are picked up from secondary windings of the line transformer as are those of the remote-control receiver and those of the deflection circuits from the switched-mode power supply. During standby mode, the synchronisation pulses of the horizontal oscillator, which is also supplied from the switched-mode power supply, are prevented from triggering the switch of the horizontal deflection stage, as a result of which there is no power consumption.

Title: High-temperature voltaic cell with a hermetically sealed metal housing and fixed fused electrolyte
Inventor: BORGER WALDEMAR DIPL CHEM DR
IPC: H01M50/434
Filed: 1982-10-28
Abstract: A high-temperature voltaic cell 1 of the Li alloy/salt melt/heavy metal sulphide system has, in view of the air sensitivity of the Li, a metal housing 4 with a hermetically sealing ceramic pole bushing 6, 7. The fused electrolyte is fixed in a matrix 5 of extremely fine ceramic material having a large internal surface area. This restricts the tendency of the fused electrolyte to creep and prevents an attack by the Li, which could otherwise be transported by the electrolyte from the negative electrodes 2 to the pole bushing, on the brazed joints 8 between the ceramic and the housing metal. <IMAGE>

Title: Operating device for a pivotable valve body of a valve
Inventor: NANZ DIETER DIPL ING
IPC: F16K31/122
Filed: 1983-02-05
Abstract: A pneumatic operating device, which is used as the actuating drive for a throttle-flap valve, for a throttle-flap valve has a piston (56) which can be displaced axially against the force of a spring (78) and executes a rotary movement during its axial displacement, by means of a curved guide (58) on the piston jacket and driver rollers (59) on the pneumatic cylinder wall (54), which rotary movement is transmitted to an output drive shaft (72) via a polygonal coupling (63, 71). Said output drive shaft (72) is connected to the valve shaft (23). The piston position which corresponds to the closed position and is occupied under the influence of the spring (78) can be adjusted by means of an adjusting element (74). A spring support (81), which is guided such that it can move in an axially limited manner on the piston, creates a unit which can be preassembled and holds the spring (78) under pretension even in the assembled state. A switching unit (69) is mounted in an encapsulated manner on the cylinder cover (55) remote from the output drive. <IMAGE>
