Title: Device for damping the self-movements of the masses of a linear two-mass oscillator
Inventor: KAUSS WOLFGANG DR ING
IPC: B60G17/018
Filed: 1987-11-09
Abstract: A description is given of a device for damping the self-movements of the masses of a linear two-mass oscillator such as that which is present, for example, in a wheel-suspension system of a motor vehicle with two spring-damper systems connected in series. The spring-damper system arranged between the two masses is assigned a controller, the actuating signal of which influences the transmission behaviour of a controlled damping member in such a way that the damping force is proportional to the sum of the separately weighted absolute velocities of the two masses. In this way, it is possible to raise the oscillation screening of the two spring-damper systems in the frequency range between the natural frequencies of the two systems and to reduce the thermal loading of the damping member.

Inventor: SUKOPP WOLFGANG
IPC: B60R22/06
Filed: 1987-12-22
Abstract: A passive safety device for restraining the occupants of vehicles, especially of cars, is described. The safety device has at least one slanting shoulder safety belt (1), the door end of which is fastened to a slide (2) which is displaceable in a guide in the lateral region of the vehicle body by means of a drive device between a storage position in which the safety belt is lifted away from the body of the occupant of the vehicle and a restraining position which brings the safety belt to rest against the body of the occupant of the vehicle. There is in addition provided an electric switching arrangement (20, 21) which can be actuated in the region of the restraining position of the slide (2) so as to emit a signal. In order to permit this switching arrangement also to provide indication of the extent to which an optimum height of the belt articulation point has been attained in the restraining position, the safety belt (1) is held on the slide (2) so as to be pivotable about an essentially horizontal axis (15), and the switching arrangement (20, 21) is intended only to be actuable when the angular position of the belt lock is within predetermined limits with respect to the horizontal, the limits of the angular position of the belt lock being predetermined in such a way that the safety belt adopts as favourable a position as possible on the body of the occupant of the vehicle. <IMAGE>

Title: Plastic housing, which can be snapped onto an apparatus supporting rail, for electrical service apparatuses
Inventor: BLUM ALEXANDER
IPC: H02B1/052
Filed: 1988-01-25
Abstract: The plastic housing (1), which can be snapped onto an apparatus supporting rail (2), has at least one snap-action leg (7, 8) which can be deformed elastically and interacts with at least one latching tab (11) which engages under the latching strips (12) on the supporting rail (2). The snap-action leg (7, 8) is integrally formed on a relatively rigid housing part (6), which is arranged in the interior of the housing (1) in the region between the outer edges of the supporting rail (2) located underneath, and projects out of the housing (1) through a housing opening (9) facing the supporting rail (2). In the event of a tear on the housing (1), this arrangement of the snap-action leg (7, 8) produces a force which forces the snap-action leg (7, 8) to form a bracket around the supporting rail (2) and thus increases the pull-off force. The plastic housing (1) is intended for accommodating electrical service apparatuses, such as contactors, thermal and/or dynamic overcurrent trip devices, motor protection circuit breakers, terminal blocks etc. <IMAGE>

Patent DE-3814852-A1 (DE)
Title: Method and arrangement for network analysis
Inventor: SCHIEK BURKHARD PROF DR ING
IPC: G01R27/28
Filed: 1988-04-29
Abstract: The patent application relates to a two-port device for determining the parameters of linear n-port networks. The device is based on the concept of the unidirectional network analyser which is extended so that port 2 can be reproducibly brought into two different states which are not known in detail. This makes it possible to measure all parameters, for example all stray parameters of any n-port networks without also applying the object being measured in the reverse direction to the measuring ports. The latter is the case in conventional network analysers of this type. In comparison with other concepts which operate without reversing the object being measured, this device is characterised by a distinctly reduced circuit expenditure. In addition, the device has the advantage that it can be calibrated with modern self-calibrating methods. For this purpose, for example, the direct connection of the two measuring ports, a matching attenuation or line of unknown attenuation or electrical length and a reflection-symmetric arbitrary two-port network which is otherwise unknown apart from a coarse estimate of the angle of the input reflection are used. In addition to these practical advantages, the method is characterised by little mathematical effort which largely consists of linear operations. <IMAGE>
