Title: Instrument console for centre of steering wheel - has magnetic coupling to steering column support
Inventor: PILATZKI BERND
IPC: B62D1/10
Filed: 1980-04-11
Abstract: The instrument console and impact protection for the centre (2) of a steering wheel is of magnetic material and is linked to the steering column support by a number of magnets (11), which lift as the steering wheel spokes (10) pass under them. The mounting is so arranged that there are always sufficient magnetic couplings to ensure a firm seating. The magnetic couplings move in fixed guides and provide a non-wearing support for the console, with a min. of drag for the steering wheel movement, using pairs of couplings with opposing poles.

Title: High voltage circuit breaker - with telescopic auxiliary moving contacts locked when on and released when off
Inventor: KRIECHBAUM KARL DR
IPC: H01H33/16
Filed: 1980-06-02
Abstract: A high-voltage circuit breaker has, parallel to at least one main pair of contacts, another pair of auxiliary contacts for the control of a switching resistor. The drive lever system of the latter is rigidly connected to that of the former so that the auxiliary contacts are opened and closed before the main contacts. The auxiliary moving pin consists of two telescopic parts. An interlock fixes them together in the ON position and a release frees them in the subsequent OFF position. The stationary contact (32) rests on a cushion of elastic material (28), pref. polyurethane, and can move against a spring (35).. This is a simple way of eliminating the extra heavy springs and interlocks, needed when the switch has to be cut out immediately after closing.

Title: Cutter and slitter appts. for battery tube electrode plates - has profiled feed rollers and pronged transport gripper for accurate indexing of tube chain section
Inventor: WIEPEN ROLF ING GRAD
IPC: H01M4/76
Filed: 1980-06-18
Abstract: The electrode tube production machine consists of two main units - a guillotine for shearing a set section of the tube chain, and a length slitter. The uncut belt of tubes is fed into the first cutting section, passing firstly over a relatively large diameter roller (3) and then through a pair of transport rollers (4,5). Surface mounted cams (6) on all three rollers, project at set intervals into the gap between adjacent tubes and progress the tube chain between guides (7) towards a second pair of rollers, the upper one of which (8) is smooth, the lower one (9) profiled, the recesses around its periphery being of the same curvature as the electrode tubes. The tube chain is then advanced to a larger profiled roller (10), above which is the transport gripper, consisting of a traverse with prongs (15) which are inserted between the tubes. Work cylinders then push the required section of tube chain to the guillotine (18). After the section is sheared, it is conveyed to the slitter, where after being cut to the required length, the tube, leaves the machine on a conveyor.

Title: Heating system utilising waste heat from barn - has heat pump with evaporator and condenser within water tank which feeds radiator in house
Inventor: JACOBSEN OLE
IPC: F28D21/00
Filed: 1980-06-19
Abstract: The heating system comprises a fan (22) within a duct (20) for evacuating heated air from the barn and conducting it to the evaporator (26) of a heat pump (10). The heat pump condenser (42) is located within a water tank (52) which is in a circuit including a radiator (16) within the dwelling. The pipe (40) constituting the condenser decreases in diameter in the direction of refrigerant flow. An air filter (30) spans the inside of a duct (6) between the intake (8) and the fan. The fan is driven by an electric motor, a V-belt and sheaves on the motor and fan respectively. Assuming that a thermostat (74), a pressure switch and thermal cut-out switch are all closed, single-phase power is provided to a solenoid, closing contacts of a switch assembly. Three-phase power is thus applied to compressor motor and to the fan motor.

Title: Cutting head drive for dredger - has flywheel masses for main gear with vibration damping coupling to auxiliary gear
Inventor: HIERSIG HEINZ M DR ING
IPC: E02F3/92
Filed: 1980-09-05
Abstract: The head of a cutting head dredger is located on the down drive shaft of a gear assembly driven by one or more motors, for work on the bed of waterways or offshore waters.

Title: Cigar wrapping leaf magazine prodn. - places stamped wrapping leaf halves on separate strips coiled on separate bobbins
Inventor: HOLTMANN EGON
IPC: A24C1/28
Filed: 1980-11-13
Abstract: The process is intended for the production of magazines for cover leaves for an automatic cigar wrapping machine. Each magazine comprises a support strip wound onto a bobbin, on which stamped-out sections of tobacco leaf, each forming the wrapping for one cigar, are accommodated one after the other. All stamping operations on each leaf are completed before work is started on the next one, the first half of the leaf being cut into wrappings (17), which are then placed in succession with the same side against a first supporting strip (14), which is wound onto a first bobbin. Immediately afterwards the second half of the leaf is cut into wrappings (17'), which are similarly placed on a second strip (24), wound onto a second bobbin (28).

Title: Burner for oil fired furnace - has fuel chamber with fuel permeable walls, which is pushed into combustion chamber by fuel pressure
Inventor: FOERSTER SIEGFRIED DR ING
IPC: F23L15/04
Filed: 1980-12-18
Abstract: The burner for an oil fired industrial furnace has a cylindrical fuel chamber (1) with porous walls (2). The fuel chamber can slide inside a heat exchanger in the form of a ceramic tube (6). The heat exchanger is enclosed in an outer tube (7) which is connected to the air supply by a pipe (8). The fuel is supplied by a pump (P) which delivers it into a lower cylinder (14). The pressure of the fuel acts on the undersurface (4) of the fuel chamber and forces it upwards against the force of a spring (24). The fuel flows through an orifice (26) into the fuel chamber and through the porous walls into the ceramic heat exchanger, where it mixes with air and burns in the separate region (9). When the fuel supply is cut off, the fuel chamber is withdrawn so that no after- burning can occur. An electric heating element (10) around the heat exchanger facilitates a cold start.

Title: Slide viewing magazine
Inventor: MUELLER HORST DR
IPC: B42F15/04
Filed: 1981-12-08
Abstract: This slide viewing magazine is composed of two transparent plastic films, which are sealed together in a grid like manner on a surface of approximately 50 x 90 cm in such a manner that many square pockets are formed, into which pockets is sealed at the top a straight, clotheshanger-like carrier having a hook.

Title: Circuit arrangement for protecting the excitation circuit of a synchronous machine having a rotor winding supplied via sliprings
Inventor: SMOLAK JAN DIPL ING
IPC: H02H7/06
Filed: 1982-01-15
Abstract: The circuit arrangement for protecting the excitation circuit of a synchronous machine having a rotor winding supplied via sliprings, which circuit arrangement indicates a defect in the excitation circuit of synchronous machines, is formed by a measurement bridge in whose diagonals a measurement element is connected through which no current flows in normal operation. In this case, no difference is indicated on a differentiating element to which voltage is supplied from shunts. In the event of a defect, the balance of the measurement bridge is disturbed, or a change in the behaviour of the currents flowing through the shunts occurs, which leads to an indication.
