Patent DE-3732753-A1 (DE)
Title: Safety coupling
Inventor: JAKOB LUDWIG DIPL ING
IPC: F16D7/08
Filed: 1987-09-29
Abstract: The invention relates to safety couplings in which driver elements (3) are supported displaceably in apertures (4) in the coupling body (1), and in which these driver elements (3) are preloaded into latching recesses (5) in the coupling body (2), and then disengaged in a known manner, counter to the force of, for example, a spring (6) in the event of overload. In the known solutions, it is necessary, on the one hand, for the freedom from rotational play of the coupling to fit the driver elements (3) tightly into the apertures (4) while, on the other hand, there is a need for play at the same point to allow easy disengagement. This problem exists irrespective of whether the driver elements (3) move radially, axially or obliquely relative to the axis of the coupling, their shape and how the preloading force is produced. Figure 3 shows the development of the circular path of the torque transmission. According to the invention, it is proposed to make the spacings between the apertures (4) different from the spacings between the latching recesses (5), the coupling bodies (1) and (2) thus being braced in an automatically adjustable manner even in the case of wear. <IMAGE>

Patent DE-3812957-A1 (DE)
Inventor: BERKEFELD VOLKER DIPL ING DR
IPC: B62D6/02
Filed: 1988-04-19
Abstract: An active four-wheel steering system for motor vehicles, with steering arrangements for the front and rear wheels is described. These arrangements act as a function of driving-condition variables fed to an electronic control unit. A variable steering-lock angle ratio with respect to the front wheels is set, a first function converter of the control unit being supplied with the input signal relating to the steering-wheel angle by a steering-wheel angle sensor and with the further signal relating to the vehicle speed by a speed sensor. This function converter produces a first output signal for the lateral acceleration, which is fed as an input signal, together with the further input signal relating to the vehicle speed, to a second function converter. To allow for a change in the driving speed, the output signal relating to the lateral acceleration is fed, together with a signal derived from the change in the driving speed, to the third function converter. This input signal, calculated in the first function converter, and the input signals relating to the change in speed, calculated in the third function converter, are converted into an output signal for an additional rear-wheel steering angle, which is superposed on the output signal for the rear-wheel steering angle. The sum of these output signals is fed as steering-angle signal to the control unit for the purpose of controlling the hydraulic steering arrangement for the rear wheels. <IMAGE>

Patent DE-3817921-A1 (DE)
Title: Coupling device for connecting two sub-units
Inventor: HEEL HELMUT
IPC: B23B31/26
Filed: 1988-05-26
Abstract: To couple a tool to a hollow spindle of a machine tool, the tool has a radially flexible sleeve which is inserted into the bore of the hollow spindle. Attached radially inside the radially flexible sleeve is a tie rod which has a shoulder surface at one end. A supporting ring faces the shoulder surface at an axial distance apart. At least one elastomeric ring body is accommodated between the supporting ring and the shoulder surface. The elastomeric ring body is compressed in the axial direction by tightening the tie rod and expands in the radial direction. As a result, it widens the radially flexible sleeve and presses this sleeve with its outer peripheral surface against the inner peripheral surface of the hollow spindle.

Patent DE-3832611-A1 (DE)
Title: Interleaving of a video signal
Inventor: PERDRIEAU LAURENT
IPC: H04N7/169
Filed: 1988-09-26
Abstract: Interleaving schemes are known which, by means of simple measures, prevent an original picture from being received by unauthorised persons. These interleaving schemes, however, have high correlation which, by means of simple measures, allows the video signal to be reproduced in the correct position by unauthorised receivers. To achieve a correlation which tends towards zero, the video signal of one line is interleaved packet by packet within these lines, the position of the lines is exchanged in one field and the fields or frames are exchanged within a number of fields or frames. The invention is used in protected broadcast transmissions.

Title: Method and circuit arrangement for continuous fail-safe testing of an infrared sensor device
Inventor: MARINITSCH WALDEMAR
IPC: G08B13/19
Filed: 1989-03-20
Abstract: Method for continuous fail-safe testing of an infrared sensor device of an alarm transmitter. The analog output signals of the infrared sensor device, for example the fundamental signals which always occur even in the absence of a dangerous situation and are caused to the thermal currents of the surrounding air, are highly amplified and converted into digital signals by level limitation. The temporal occurrence of these digital signals is monitored, it being assumed, when during a certain time interval no digital signals occur, that the infrared sensor device is faulty. In this case, a corresponding fault alarm is triggered.

Patent DE-3911230-A1 (DE)
Inventor: SCHEFFEL GUENTER DR
IPC: C07F9/46
Filed: 1989-04-07
Abstract: The abovementioned compounds are prepared by reacting trialkyl phosphites with phosphorus trichloride and/or monoalkyl esters of dichlorophosphinous acid at -20 to +100 DEG C followed by immediately reacting the product with alkylmagnesium chloride or alkylmagnesium bromide at -60 to +50 DEG C, followed by removing the desired compounds from the distillate of the volatile compound. This allows dialkyl esters of alkylphosphonous acids and monoalkyl esters of dialkylphosphinous acids to be obtained without complicated and costly purification of intermediates. The phosphorus-containing esters obtained, in turn, are valuable intermediates, for example for the preparation of flameproofing agents and crop protection agents.
