Patent DE-3526176-A1 (DE)
Title: Control circuit for an electric motor
Inventor: SCHEIDEL WOLFGANG ING GRAD
IPC: F04D27/02
Filed: 1985-07-23
Abstract: A control circuit is proposed for an electric motor (12) for driving a vehicle fan (30) having forwards-curved blades on the fan wheel. This generic type of fan is sensitive to the load being relieved by ram pressure, which can result in the drive motor being overloaded. The control circuit contains an overload protection device (13, 14) whose overload signal (31) interrupts the power supply to the drive motor (12) until a signal (32) for switching on again cancels the interruption state again. The signal (32) for switching on again is derived from the voltage which is produced on the electric motor (12) when it is being driven backwards in the generator mode. <IMAGE>

Title: Motor vehicle
Inventor: BIENERT HERBERT
IPC: B60S1/56
Filed: 1985-09-14
Abstract: A motor vehicle with a vertically adjustable window pane and a wiper system for cleaning this window pane is described, measures being taken such that even with a partially opened window the window wiper does not experience spring compression travel into the interior of the motor vehicle. This is achieved in principle in that the wiping angle of the window wiper is changed as a function of the position of the window pane.
Patent DE-3533386-A1 (DE)
Title: Twin-tube vibration damper with spring-loaded hydraulic compression stop
Inventor: GRUNDEI MANFRED ING GRAD
IPC: F16F9/49
Filed: 1985-09-19
Abstract: The object of the invention is to provide a twin-tube vibration damper with a spring-loaded hydraulic compression stop of simple construction, high reliability of operation and small overall length which does not give rise to any noise and allows unproblematic installation. This is achieved by virtue of the fact that, after a certain compression travel of the piston rod, a stop spring connected to the latter interacts with a control body and this control body considerably reduces the cross-section of passage of the pressure regulating valve arranged in the bottom valve. The control element is a control spool subject to the action of a return spring, connected to the bottom valve and capable of moving axially between two stops. It has a stop surface for the stop spring.

Patent DE-3603695-A1 (DE)
Title: Hydraulic brake pressure sensor, especially for motor vehicles
Inventor: GATH DIETMAR
IPC: B60T13/12
Filed: 1986-02-06
Abstract: A hydraulic brake pressure sensor, especially for motor vehicles, is described with a booster (4), to which servo pressure can be fed from an external energy supply system, at least one master cylinder piston being provided, which defines a working chamber, in which the brake pressure is built up and which can be connected by way of a valve device (76, 88) to a tank (94) at zero pressure. In order to achieve a transmission shift by simple structural means in the event of a servo power failure, it is proposed that the master cylinder piston (34) define a chamber (48), which is enlarged in the actuating direction when the master cylinder piston (34) is displaced and which can be connected by way of the valve device (76, 88) to the working chamber (36) and the compensating vessel (94). <IMAGE>
Patent DE-3605115-A1 (DE)
Title: Spot-welded joint between adjacent sheets and method of making the spot-welded joint
Inventor: MUELLER KLAUS
IPC: B23K11/14
Filed: 1986-02-18
Abstract: A spot-welded joint, which can be made by means of electric resistance welding, between two sheet elements (23, 24) adjacent to one another in a flat-spread manner, of which one, at the intended welding point, has a projection extending towards the other sheet element to be attached and melting with the material of the other sheet element during the spot-welding operation, is distinguished by the fact that the projection (25) is designed in a linear shape, in particular an annular shape or a circle shape. In this way, damage to the surface structure of the sheets at the welding point and in particular damage to surface coatings (e.g. galvanising) can at least be largely avoided when the welding parameters are suitably selected.   <IMAGE>

Abstract: In this adder circuit, a partial summand with the value 5 is processed in the main circuit (1) and the dual half adder (7) even if there is only one partial summand with the value 5 at the inputs of the dual half adder (8). Thus, in the main circuit (1), the numeric value 4 is additionally processed, and in the dual half adder (7) the value 1 is processed. The number of required individual adder circuits (12) of the main circuit (1) is reduced from 28 to 21 by the circuit (9). <IMAGE>
Patent DE-3625864-A1 (DE)
Inventor: NEIDECKER RUDOLF DIPL ING
IPC: H01R13/15
Filed: 1986-07-31
Abstract: An electric contact device for an electrical connection of electroconductive connectors comprises a row of interconnected contact elements which are joined together by at least one continuous band-shaped or wire-shaped spring element. Each contact element is provided with at least one opening through which the spring element extends. The opening provides for fixing of the contact element which, in an unstressed condition, extends at an angle maximum 45 DEG relative to the plane of the spring element. Under the contact pressure, the spring element is deformed and takes a wave form, thus, producing a resilient force. This permits to assemble the device with larger tolerances for spacing between the contact elements. Preferably, the edges of the contact elements have a high electric conductivity.

Patent DE-3636549-A1 (DE)
Title: Process for slag-free casting of molten metals
Inventor: HEINZ WILLI DIPL ING
IPC: B22D1/00
Filed: 1986-10-28
Abstract: In a process for refining and/or casting molten metals, a refining slag and/or covering slag being added to the melt, the object is, on the one hand, to avoid surface contact of the melt with the atmosphere, but allowing slag-free casting of the melt and, furthermore, preventing contamination of the ladle lining. As a solution for this, it is proposed to add to the melt an Al2O3- and CaO-based slag in the premelted physical state in such a ratio to the weight of the melt that, after the melt/slag reaction, a stable lid-like slag plate forms on the surface of the melt.
Patent DE-3641545-A1 (DE)
Title: Force-measuring head for a resistance-welding apparatus
Inventor: KRAUSE H-J DR ING
IPC: B23K11/25
Filed: 1986-12-05
Abstract: The invention relates to a force-measuring head for a resistance-welding apparatus. The force-measuring head is used in resistance welding for determining the variation of the electrode force over time. The electrode force is, in this arrangement, measured by a force transducer which is subjected to mechanical prestressing and is located in the interior of the measuring head. The prestressing is applied by a plate spring. With a specific plate-spring cross-section which is required for the welding current, the rigidity of said spring can be reduced in a simple manner with respect to solid-body configuration by slots and cavities and a spring characteristic coordinated with the force transducer can be established. The disadvantageous influence of the heating, in the case of the current throughflow during the welding procedure, on the prestressing force is reduced by this and by an additionally provided possibility of cooling the plate spring.

Title: Emergency life-saving apparatus for climbers
Inventor: HOFFMANN SEN KURT
IPC: A62B99/00
Filed: 1987-01-28
Abstract: According to information supplied by the German Alpine Club and Mountain Rescue Services, one thousand climbers fell to their deaths in the whole of the Alps in 1986 alone, including many well equipped and experienced climbers and fewer "track shoe tourists". It is also officially confirmed that climbers attached to ropes, if they fall, can easily pull other climbers attached to the same rope to their deaths with them. The present invention demonstrates how with the aid of individual balloons, which can be inflated in seconds, a falling climber can have his fall arrested by the supporting power of the balloons and float down to life-saving solid ground.  Technical:     3-4 balloons, each of 5 cubic metres capacity,   a plurality of gas cartridges (mini-gas bottles), well secured, gas cylinder valves which, in an emergency, let the gas escape into the balloons at lightening speed. Always ready to hand: rip-cord for gas valve opening and balloon ejection.   All in a box-shaped small container in the upper part of a back-pack frame, the balloon retaining lines being firmly anchored to and secured on the frame. With observance of certain safety checks, valve system, balloon retaining hooks, safety belts, this invention can in future reliably save the lives of many climbers who would otherwise have suffered fatal falls.

Filed: 1987-09-10
Abstract: The lips I, II, III of a twist drill, here designed as a three-lipped drill, are subdivided by chip-breaking flutes (15) running transversely to the lip into individual lip elements (16) which are provided with gaps in between and release individual narrow chips. The latter are broken into segmental chips which can easily be conveyed further. The respective three flutes (15 and 153) of the lips I and III pass through approximately the same surfaces of revolution, between which the surfaces of revolution of the chip-breaking flutes (15) fit. This also applies to the circumscribed circles of the lip elements (16) of the lip II relative to I and III. The individual lips can be replaced according to the representations I1 to I7 by such according to the representations under the three lips I, II and III. The width and arrangement of the chip-breaking flutes (15, 152, 153) can be matched to one another in such a way that the torsional moment acting on the twist drill acts symmetrically to the drill axis. <IMAGE>

Patent DE-3734884-A1 (DE)
Title: Stove cover
Inventor: LAMPKA BRUNO
IPC: F24B13/00
Filed: 1987-10-15
Abstract: A plurality of identical panels (14) are connected to one another without screws by mutual hooking. Each panel (14) consists of a bottom wall (16) and two edge webs (18, 20), one of which has a web section (20) projecting at right angles and the other of which has a double fold (24). The latter consists of two oblige flange sections (26, 28) located at an angle relative to one another, the inner edge of which sections lies on the same level as the web section (22). The clearance between this inner edge of the multiple fold (24) and the web (20) is equal to the width of the web section (22) on the other web (18). As a result, the double fold (24) of one panel (14) grips positively around the web section (22) of a neighbouring panel (14) and presses the two neighbouring webs (18, 20) close together. The two panels (14) can only be displaced in the longitudinal direction relative to one another. By means of the panels (14), cover for stoves of any width can be constructed in a short time. <IMAGE>

Patent DE-3801926-A1 (DE)
Title: Folding roller skates
Inventor: RIENKS GERD
IPC: A63C5/06
Filed: 1988-01-23
Abstract: Rollers are to be moved only slowly. Rocker-type rollers have a mechanism with poor efficiency. In the solution presented here, propulsion is achieved by means of a folding joint in conjunction with a non-return lock. The same benefit can also be achieved with cross-country type skis, as a result of which the climbing of hills is easier. Folding roller-skates (summer) and folding skis (in winter) are a movement-friendly new form of sport in which relatively large distances can be covered quickly.
