Title: Printed circuit board
Inventor: WIEZOREK HEINZ-WERNER
IPC: H01R12/52
Filed: 1987-03-20
Abstract: In the case of a structural unit which is formed from a printed circuit board (1) and a hybrid (2), the plugs (3, 4) which connect these two parts to one another each have a sprung region (8, 9) which is formed by a section of the plugs which is bent in a V-shape. In consequence, the hybrid (2) can spring relative to the printed circuit board (1), as a result of which the structural unit is less sensitive to shock. <IMAGE>

Title: Electropneumatically operating rotary percussion hammer drill
Inventor: KRETSCHMAR PETER DIPL ING
IPC: B25D16/00
Filed: 1987-04-11
Abstract: The structural design of the known electropneumatic rotary percussion hammer drills offers, at best, only little room for manoeuvre as far as a reduction in the overall length and overall volume is concerned.   A more compact construction of rotary percussion hammer drills can be achieved by constructing the rotor shaft (3) of the drive motor (1) as a hollow cylinder bush for receiving the freely movable percussive element (4) and for guiding the drive piston (5) (Fig. 1). With such a percussive-mechanism design, handy hammer drills with sufficient percussive power can be produced. <IMAGE>

Title: Process for producing a wear-resistant coating
Inventor: SIMM WOLFGANG DR
IPC: C23C4/18
Filed: 1987-05-08
Abstract: A process for producing a wear-resistant coating with application of a metallic base alloy, in particular an Ni-Co-Fe base alloy, to a workpiece is improved if the applied coating is aftertreated with a high-energy beam for modifying the surface structure down to 0.5 mm depth, the depth of penetration being a fraction of the layer thickness. The depth of penetration is determined, for example, by defocusing or control of the laser energy or by matching the speed of advance in the X axis or by overlapping of the treatment zones.
Patent DE-3715756-A1 (DE)
Title: Electric signal transmitter, in particular a warning indicator for brake fluid containers
Inventor: KERNICH HANS-GEORG ING GRAD
IPC: B60T17/22
Filed: 1987-05-12
Abstract: An electric signal transmitter (1) for the indication of a liquid level in a compensation container of a hydraulic vehicle braking system is described, which has a contact carrier (3) which contains a switching contact (8) and is able to be connected to a monitoring circuit by means of contact pins (7). To activate the switching contact (8), a plunger (4) connected to a float (5) is displaceably mounted in a bore (9) in the contact carrier (3). A transmitter piston (13), mounted in a cross-bore (12), supports itself on the plunger (4) under the effect of a switching spring (16), and the plunger is connected via a contact bolt (18) to a contact plate (12). The plunger (4) has a constriction (10), which in the signal position lies opposite the cross-bore (12), so that the transmitter piston (13) is moved out of the cross-bore (12) by means of the switching spring (16), and the contact plate (21) can be lifted off the contact pins (7). By this means the switching contact (8), which is designed as a normally closed contact, is opened and the monitoring circuit is switched. By means of the indirect activation of the switching contact (8) by means of the transmitter piston (13), false switching caused by fluctuations of the liquid level are avoided, and favourable closing forces between the contact plate (21) and the contact pins (7) are made possible. <IMAGE>
Patent DE-3720949-A1 (DE)
Title: Membrane (diaphragm) for electroacoustic transducer systems
Inventor: FALKENBERG WERNER
IPC: H04R7/12
Filed: 1987-06-22
Abstract: The focused emission and disruption of the tone structure led to two conical membranes which emit omnidirectionally, move in a rolling-off manner and [lacuna] of a plurality of trapezoidal, straight, inflexible and reinforced [lacuna], connected by means of folds, form the closed membrane body which is arranged axially symmetrically between two oscillating systems. Rotation-point positions on the membrane elements cause phase-rotating membrane parts and severe distortion. The invention uses curved, elastic membrane elements which become more rigid towards the oscillating coil and do not rest against one another in the equatorial region but are connected at a distance by elastic angle brackets and have no angle-forming transitions and rotation points on the oscillating coil. Furthermore, subsections of the membrane body are excited more strongly in terms of oscillation by means of additional transducer systems which can be integrated in a damping body (which stands proud in the membrane body) and are in each case aligned radially with respect to the relevant membrane elements. The uneven distribution of the radiation intensity enables, in the case of the transducers being arranged to match the direct and indirect sound components to the acoustic conditions in the room, as a result of which the optimum hearing position is no longer linked to one location and the production of a sound can nevertheless be localised and remains fixed in position.

Patent DE-3731668-A1 (DE)
Title: Differential with limited self-locking for a motor vehicle
Inventor: BOTTERILL JOHN R DIPL ING
IPC: F16H48/11
Filed: 1987-09-21
Abstract: The invention relates to a self-locking differential transmission in which carrier plates 8, 9, axially jointed to the planet carrier 5 and capable of swivelling about an axis arranged eccentrically to the axis of rotation x-x, are provided. The carrier plates 8, 9 carry brake shoes 10, 11, which are supported against inner surfaces 12, 13 of internal gears 1, 2. The two planet gears 3, 4 engage in one another. In addition, each of the planet gears 3 and 4 meshes with an internal gear 1 and 2, respectively. According to the torque to which the planet gears 3, 4 are subjected, a corresponding brake torque is produced acting on the respective internal gear 1, 2. Due to the design of the carrier plates 8, 9 and the brake shoes 10, 11, 10a, 11a, the desired locking ratio can to a large extent be constructively influenced both for the drive and for thrust. <IMAGE>

Patent DE-3733716-A1 (DE)
Title: Grip for roller-blind and slatted-blind pulling means
Inventor: ZENTGRAF WALTER
IPC: E06B9/326
Filed: 1987-10-06
Abstract: The invention relates to a grip for roller-blind and slatted-blind pulling means, which comprises two grip parts which can be fitted, without the use of tools, on the ready-mounted tape and are connected by means of a securing element. By clamping the tape manually between friction elements in the upper grip part and protuberances in the lower grip part, the tape can be moved. The tape (or one or more cords) is guided, in the extended state, through the grip, with the result that, upon manual clamping, it grips the tape in a frictionally locking manner, but, when the clamping force is removed, it slides downwards along the tape as a result of its own dead weight.

Title: Valve arrangement for the control system of a gearbox
Inventor: RUEB WINFRIED DIPL ING
IPC: F16H61/02
Filed: 1988-10-17
Abstract: A description is given of a valve arrangement for the control system of a gearbox, in particular a powershift gearbox, with a plurality of gear-shifting elements, such as for example gear-shift clutches, which can be activated selectively for changing various gears. To change the various gears the shifting members are assigned a central shift valve which has at least a number of shift positions which corresponds to the number of gears, in which positions, on the one hand, the supply pressure is imparted to at least one selected shifting member and, on the other hand, at least one further shifting member is relieved of load. Connected upstream of the central shift valve is a control valve, the starting pressure of which, which determines the position of the shift valve, can be adjusted by means of an adjusting device. This valve arrangement makes it possible to reduce the number of relatively costly magnets and, at the same time, to provide the prerequisite that the control valve, which is connected upstream, may be used in order to match the shift pressures to the load condition.

Title: Device for testing the immunity to interference of electronic devices or systems
Inventor: FRITSCH KARL DIPL ING
IPC: G01R27/28
Filed: 1988-11-07
Abstract: A device 14 to be tested with respect to its immunity to interference is loaded with a signal of a tunable frequency from a signal generator 10 via a directional coupler 12 and a measuring lead 13, and the reflected signals are fed via the directional coupler 12 to an evaluation device 20. For the case that the device to be tested has a voltage applied to it or is connected to a further device 26, a high-pass filter 22 is arranged between the directional coupler 12 and the device 14 to be tested and, if necessary, a low-pass filter 24 is arranged in front of the further devices 26 (Fig. 1 and Fig. 2). Directional coupler 12, measuring lead 13 and high-pass filter 22 can be combined constructionally into a sampling head 15 (Fig. 3). By additionally building a rectifier and amplifier arrangement 28 into the sampling head 15' (Fig. 4), the reflected and already transformed signal can be transmitted to the evaluation device 20 without a radio-frequency-matched lead. With the application of suitable means, according to Claim 5, the reflected and transformed signal can be transmitted via the lead coming from the signal generator 10 and can be coupled out to the evaluation device 20 at the end of this lead (Fig. 5). <IMAGE>
