Title: Magnetic tape record and replay unit - operates by dividing signal into amplitude ranges each assigned own gain to compensate for amplification transition steps
Inventor: VOCKENHUBER PETER
IPC: H04B1/64
Filed: 1979-09-19
Abstract: The replay and recording device has an analyser dividing the signal describing the original event into different amplitude ranges. The signals falling within each amplitude range are amplified. At least those amplifiers serving those amplitude ranges assigned to signals of average magnitude have a constant gain. In order to compensate for the jump occurring when the signal moves from one amplification level to another, the dc level of the upper or lower half wave is increased or decreased using an adder that adds the voltage source controlled by the analyser to the amplifier signal.

Title: Telegraph transmission system with timing monitor - has cyclical timing criteria to ensure error free transmission to selected one of multi-terminal network
Inventor: RUPP DIETER DIPL ING
IPC: H04Q9/00
Filed: 1980-02-05
Abstract: Telegraph transmission system with timing frame criteria to prevent overlap of telegram transmissions and a fast system restoration in the event of line interference or system failure in part or entirety. The system uses a cyclical timing algorithm to determine whether a station is the correct one to receive a transmission and whether it is in working order. Two determining time factors are the first time (t1) which is at least equal to the maximum transmission time (T) to the most distant terminal and a second time (t2) which is equal to the cyclical framing time (tz) of the system. Address codes and receive acknowledge levels between stations are checked against the algorithm and its equations tn=a.sn.t to verify station readiness to receive a telegram transmission, where a is a factor greater than 1 and sn is a time stacking and holding factor relating to transmission time to stations and the stations out of service.

Title: Phase detector circuit
Inventor: TAGUCHI SHINISHIRO
IPC: H03L7/08
Filed: 1981-02-24
Abstract: A horizontal sync signal is applied as a reference signal pulse to a first input terminal of a phase detector (23) and furthermore as a keying or gate control pulse to a gate circuit (25). The output signal of a frequency divider (28) which divides the frequency of the output signal of a voltage-controlled oscillator (27) is applied as a comparison pulse to a second input terminal of the phase detector (23). In the phase detector (23), a phase detector or measurement pulse is obtained with a pulse width which is proportional to the phase difference between the reference pulse and the comparison pulse. This phase measurement pulse is fed in via a buffer (24) of a gate circuit (25). In the gate circuit (25), the current path from the phase measurement pulse input terminal to the output terminal is held conductive or through-connected during the cycle of the gate control pulse, an output pulse being obtained during this cycle which contains the aforementioned phase measurement pulse as a component. This output pulse is smoothed by a filter (26) and fed into the voltage-controlled oscillator (27) as an oscillation frequency control input voltage. <IMAGE>

Title: Castor which can rotate about a vertical axis
Inventor: KLOSE ODO PROF
IPC: B60B33/02
Filed: 1981-03-21
Abstract: The invention relates to a castor which can rotate about a vertical axis. Said castor is mounted on a lever arm and can be locked by means of brake blocks which are located on the castor housing or support, the locking of the castor wheel or the frictional engagement of the brake blocks taking place by the action of a spring which acts on the lever arm. Castors of this kind are used in particular on mobile chairs. They lock the chair when relieved of load and unlock it automatically when loaded. Hitherto, there was the problem of matching on the one hand the opposing forces of the weights of the chair and the chair user and on the other hand the rolling away resistance to be be overcome by this loading which varies considerably in each case by means of the spring force despite the contrary effects in such a way that the travel wheel remains nevertheless functionally reliable and uncomplicated. This object is achieved according to the invention in that the rolling away resistance which originates from the spring is variable in such a way that the spring is inserted in the roller housing or support in an interchangeable and/or readjustable plug-in arrangement. <IMAGE>

Patent DE-3118565-A1 (DE)
Title: Multi-disc clutch
Inventor: SCHREINER FRIEDRICH ING GRAD
IPC: F16D25/0638
Filed: 1981-05-11
Abstract: A multi-disc clutch with diaphragm springs generating the contact-pressure force is held in the open position of the clutch in a latching device which comprises pressure-exerting pieces and cutouts with stops in the outer disc carrier. The pressure-exerting pieces also interact with an individually axially displaceable plate which, in the event of non-latching, transfers the pressure of the diaphragm spring to the disc assembly. The pressure-exerting pieces are predominantly spheres or cylinders and may be arranged on or in the individually displaceable plate. For unlocking, the pressure-exerting pieces are pressed radially inwards by a piston which can move, via a pressure medium, in two axial directions, with the result that said pressure-exerting pieces are released from the stop and are pressed onto the discs via the individually displaceable plates. Via a drag device which acts on the individually displaceable plate, the same piston opens the clutch, counter to the pressure of the diaphragm spring, until the pressure-exerting piece can once again latch into the cutout of the disc carrier. <IMAGE>
