Title: Digital telephone subscriber's appts. with multiplexer - has key pad command to control multiplexing or de-multiplexing of 8 kilobit data channel
Inventor: HEUER CLAUS DIPL ING
IPC: H04M11/06
Filed: 1980-02-20
Abstract: The telephone subscriber's appts. for a digital network has a multiplexer to enable data to be transmitted or received in an 8 k bit per sec. part of the 64 k bit per sec. speech channel. Operation of buttons on the instrument's keypad initiates commands to the intermediate storage latch (Latch) and control circuit (ST) which change the operational mode, during the progress of a call, from purely speech to speech plus data. The keypad signals also initiate the clock pulse signals which control the instrument's internal multiplexer (MUX) thereby providing the data transmission (is-ob) and speech transmission (is-ib) for the appropriate time frames. The data channel latch repeated signal is sent via a parallel/serial data (S/P) converter so that the serial data are clocked out by a signal (bt) from the exchange (ue). The latch, multiplexer and parallel/serial converter are on an integrated circuit and the receive side demultiplexer serial/parallel converter (S/P), receive store and counter are on another integrated circuit. The speech path uses an a-d delta-modulated converter.

Title: Ignition circuit for mercury vapour rectifiers - uses capacitor voltage as voltage pulse for arc excitation, with intercoupled thyristor
Inventor: KREMP KARL HEINZ
IPC: H02M1/04
Filed: 1980-06-04
Abstract: The mercury vapour rectifier has an ignition pin, which can be supplied with a voltage pulse for ignition of an excitation arc. The voltage pulse is provided by a voltage charge of a capacitor (C) coupled to the ignition pin (Z). via an intermediate connection of a thyristor (V). The latter is ignited across a contact (K2) of a relay (K), incorporated in the excitation circuit of the rectifier (G). This manner the known ignition relay for light arc maintenance is replaced by contactless ignitor(s), which eliminates mechanical switching with resulting abrading and erosion. Since the thyristors service life is practically unlimited the failure incidence of the mercury vapour rectifier is almost completely eliminated, as far as it may be caused by light arc quenching.

Title: Method for monitoring screwing processes
Inventor: MAYER EBERHARD DIPL ING DR
IPC: B25B23/14
Filed: 1981-07-18
Abstract: In the known methods for monitoring screwing processes, in which the tightening torque of the screwing action is measured as a function of the change in the angle of rotation, the differential quotient of the torque relative to the angle is formed and this quotient is used as parameter for measuring an angle of rotation, because of the displacement, caused by friction and/or other influences, of the initial point of the measurement of the angle of rotation there are generally no defined conditions existing at the end of the screwing action. It is the object of the invention to provide a remedy in this regard. This remedy is achieved by making use of the rise in the curve defined by the gradient G =  DELTA M/ DELTA  phi  in the approximately linear region of the curve relating the torque and angle of rotation to determine or to correct the starting point for the measurement of the angle of rotation in such a way that this starting point is used by means of a rise in the curve defined as a multiple of the gradient G in order to determine or to correct the starting point of the measurement of the angle of rotation in such a way that this starting point is determined by means of a threshold torque MS = K x G, defined as a multiple of the gradient G, or by means of extrapolating the straight line of the rise determined by the gradient G back to the theoretical zero torque. <IMAGE>

Title: Mobile cable store
Inventor: MOEHLER HELMUT
IPC: H02G11/02
Filed: 1981-11-06
Abstract: Connecting cables and also cable drums, from which a plug cabling can be unwound and connected to the power source, and to which a plurality of loads can also be connected, are used for connecting a power source to a load. Since the plug sockets of the cable drum rotate with the plug drum, the loads can be connected only at the point of use. The invention overcomes this disadvantage by the support of the plug socket (which, however, is continuously electrically connected to the plug cable by means of a rotating coupling) being provided independently of the plug drum. The load may thus be connected even before transportation of the cable store and may even be used during transportation. An exemplary embodiment of the invention is shown in Fig. 1. <IMAGE>
