Patent DE-4211849-A1 (DE)
Inventor: HEIBEL HELMUT
IPC: B60T13/57
Filed: 1992-04-08
Abstract: In an assist device housing (10), two chambers (12, 14) are separated by a movable wall (16) which is connected to a valve housing (22). The latter contains a movable sealing member (60) to which are allocated a first valve seat (24) formed in the valve housing (22) and a second valve seat formed on a movable valve body (30). The valve body is axially movable on a piston (42) and forms the armature of an electromagnet (40) arranged inside the valve housing (2) in such a way that, when excited, it moves the valve body (30) away from the sealing member (60) against the force of a valve spring (38). The piston (42) is axially movable in the valve housing (22) and transmits actuating forces from an actuating member (44) to a force transmission member (50). On the piston there is a stop element (52) which extends outwards with axial clearance through radial recesses (34, 36) in the valve body (30) and the valve housing (22) and, when the actuating member (44) is not actuated, defines a shared inoperative position of the valve body (30) and the piston (42) by contacting a stop (54) formed on the assist device housing (10). In this inoperative position the valve spring (38) holds the valve body (30) against the stop element (52) and, at the same time, the second valve seat (32) against the sealing member (60).

Title: Process for the manufacture of wires which are especially suitable for cathodes of electron tubes
Inventor: GELLERT BERND DR
IPC: C23C8/02
Filed: 1993-02-24
Abstract: A process for the manufacture of wires is indicated, which are suitable especially for cathodes of electron tubes and are distinguished by a high emissivity and mechanical stability. The process comprises a tempering step and a carburising step. In tempering, the temperature (T) is raised at a defined rate of rise (dT/dt1) from a starting temperature (T0) to an end temperature (T1), kept constant during a certain holding time (th) at this end temperature (T1) and lowered again to the starting temperature at a rate (dT/dt2) whose amount is smaller than the rate of rise (dT/dt1). This gives considerably enlarged grain sizes in the wires. Such grain sizes are necessary, so that the wires have the stability required for large, self-supporting cathodes. <IMAGE>

Filed: 1993-03-03
Abstract: The invention relates to a transmission lock for bicycles, consisting of a closing and locking system for blocking rotational movement of the pedal shaft and securing its axial position in the bottom bracket ball bearing housing.

Title: Electrical switching installation
Inventor: LEONHARDT GUENTER
IPC: H02B13/025
Filed: 1993-04-19
Abstract: In the case of a gas-insulated medium-voltage switching installation which is formed from a plurality of switch panels (1, 2, 3), a passage from the individual switch panels into a common expansion channel (8) is opened by overpressure as a consequence of an arcing defect. This is predicated on a relatively high pressure response level, for which the encapsulation of the individual switch panels must be designed. The invention now places an expansion vessel (19) into this exhaust path, which expansion vessel (19) compensates for virtually all the pressure fluctuations below the arc response pressure in order to be able to implement installation encapsulation which can be designed for the minimum possible overpressure. <IMAGE>

Title: TDM/FDM radio system
Inventor: GRUDNER UWE DIPL ING
IPC: H04B7/26
Filed: 1993-08-24
Abstract: FDM/TDM radio systems with mobile stations and a base station are known, to which one or more remote RF transceiver stages are connected by means of optical transmission links. These in each case supply one radio cell in that they convert the RF radio signals into optical signals and vice versa. Signal processing is handled exclusively in the base station. The RF transceiver stages in each case receive at several carrier frequencies one radio signal having a received level which changes from time slot to time slot. As a result, the compound FDM/TDM signal to be transmitted optically to the base station has an unwanted high dynamic range at any time. Accordingly, the use of technically complex assemblies is required for the optical transmission. It is the object of the invention to provide a radio system and a method for an FDM/TDM radio transmission in such a manner that the abovementioned problem is solved. The mobile stations (Ma...Me, Mx...Mz) are in each case allocated, at their carrier frequency (fo...fn), a time slot (s1...s8) for transmitting the radio signal, in dependence on the received level generated by this radio signal at the location of the RF transceiver stage. To this end, the base station determines the respective received level (A) and allocates the same time slot (s1), via a signalling channel, to those mobile stations (Ma, My) which generate approximately equally large received levels. This [lacuna] a distinctly reduced dynamic range of the received level ... Original abstract incomplete. <IMAGE>

Patent DE-4333662-A1 (DE)
Title: Measuring probe
Inventor: ADARCZYN GREGOR
IPC: G01R1/067
Filed: 1993-10-02
Abstract: When measuring electrical capacitances of current and voltage values, frequent use is made of mostly hand-guided measuring probes, which are positioned on the object to be measured and sample, and optionally display, the quantities to be measured. If, in this case, a rigid measuring or sampling element strikes a positionally fixed live (voltage-carrying) body, the voltage carrier and the voltage display elements can undergo oscillations and irregularly changing measured values are then displayed. The invention serves the purpose of counteracting triggering of oscillation at the voltage carrier and display element, in conjunction with the measuring process in the case of electrical measuring probes, and of damping the oscillations produced. In order to achieve this object, according to the invention at least one of the two interacting measuring or sampling elements are cushioned with springs relative to the other. In this case, the tendency to oscillate is damped at a reduced oscillation amplitude, which, above all in the case of mechanical display of the measured value, is observable, for example, through reduced "jitter" of the display needle.
