Title: Synchronisation system for PCM TDM telephone network - compares local signals with control signals describing position and duration of received blocks
Inventor: WINTZER KLAUS
IPC: H04L7/04
Filed: 1978-08-14
Abstract: The synchronisation system establishes synchronisation between a PCM telephone exchange and its PCM subscriber stations using signal blocks comprising coded voice signal word preceded by signalling and sync. bits. Both states of the bits in the signals are represented by signal variables that differ from the signal state prevailing during breaks in transmission. Control signals are derived from received blocks and describe their position and duration. A receiver register is enabled to receive signal blocks serially when these control signals coincide with signals generated locally by a counter. The contents of the register's output stages are evaluated to established synchronisation.

Title: Model trolley-bus with remote speed and steering control - with DC power supply and steering control by variable mark-space ratio square wave signal
Inventor: CHRISTOFFERS DIRK DR
IPC: A63H19/26
Filed: 1979-05-31
Abstract: A model electric trolley-bus has current collectors running on a pair of overhead wires. Speed, forwards or backwards, is remotely controlled by the voltage and polarity of a DC supply fed to the wires via a choke. A servo motor, coupled to the steering, is powered by a 10kHz square wave superimposed on the wires. The steering is remotely controlled by varying the mark-space ratio. In the model, the 10kHz is separated and rectified to provide DC for the servo. A R-C integrator derives a voltage proportional to mark/space and a feed-back potentiometer on the steering gives proportional position control.

Title: Dilatation catheter - with piercing spiral for transluminal removal of coronary blockages
Inventor: RENTROP KLAUS PETER DR MED
IPC: A61B17/22
Filed: 1979-06-11
Abstract: A catheter assembly for the transluminal recanalisation of coronary blood vessels of the heart which are blocked consists of a guide catheter and an inside dilatation catheter. Both are made of plastic tubing, slightly curved at the distal end. A wire spiral of very small dia. with a soft point can be moved forward in the dilatation catheter to straighten its curvature or to restore it. Still further forward movement pierces and removes the coronary blockage. This can be used both to expand narrow veins and to pierce any existing blockage so that the blood circulation is restored and the cells are revived.

Title: Time period synchronising circuit - is for noise frequency suppression and uses periods with noise frequency but random phase
Inventor: SPIESBERGER GERHARD DIPL ING
IPC: H03M1/00
Filed: 1979-07-13
Abstract: A circuit for synchronising time periods for processing measurement signals at the frequency of periodic noise signals superimposed on the useful signals is appliable e.g. to high accuracy integrated analogue-to-digital converters. It avoids the high expense of phase-locked-loop synchronisation which also involves large lags in response to sudden noise frequency variations. Time periods are produced with the frequency of the noise but with any phase position. A counter of clock pulses (4) is periodically reset by a pulse signal derived from the noise signal. Its outputs are input to a register activated by an AND gate with one randomly triggered input and one driven by the clock pulses. The counter outputs are compared (7) with the register contents. When they coincide the resulting comparator pulses are used as measures of the time period, and recorded in a period counter (8).

Title: Bearing support for damping axial movement of rotors - has plastic bush each end of rotor shaft supported by steel spring spider
Inventor: ZINSSER RUDOLF DR ING
IPC: H02K5/167
Filed: 1979-11-21
Abstract: The rotor shaft (2) of a small electric motor passes through, and is held by sleeve bearings (3), which are captive in the bearing holder (6). A bush (7) is made of a thermoplastic material is fixed on the rotor shaft (2) at each end of the rotor (2), and is supported from the face of the rotor end by a number of axially arranged spring strips (8) one of which has a projection at its end (9) which fits into a recess (10) in the face of the rotor This avoids differential slip and the spring strips themselves (8) take up any play between the rotor and the sleeve bearings (3), by holding the plastic bush (7) against the face of the bearings.

Title: Drain valve forming automatic gas seal - comprises float held above seat by fluid in vessel
Inventor: WIENEN KURT ING GRAD
IPC: F16K31/20
Filed: 1979-12-14
Abstract: The drain valve is for a vessel having a union for compressed gas used to expel the fluid contained, particularly where this is chemically aggressive. Its plug is in the form of a float (7), whose buoyancy causes it to be held in the open position above its seat (20,21) by the fluid. It drops onto the seat under gravity once the vessel is emptied, thus shutting off the gas automatically. The plug can be spherical and hollow, while there can be a cage (8,22) above the seat partly accommodating it and limiting its opening movement.
