Title: IC engine fuel pulse timing system - has sawtooth waveform and rectangular pulse generators and gate elements passing signals to voltage convertor and comparator
Inventor: HAASE GERHARD
IPC: F02D41/24
Filed: 1977-05-18
Abstract: The control system for fuel injection mixtures fed to internal combustion engines includes a multiplier (30) which combines a signal (Ei) from the track speed sensor (25) with a signal (E2) from the analogue store (50). Timing signals are formed by a sector disc (110) which gives a sawtooth waveform output and is axially coupled with another disc with rectangular teeth producing pulses of equal breadth. The rectangular pulses (20) are passed through a gate element (24), which also receives signals from a time measurement generator (23). The joint output from the gate (24) is passed to a voltage convertor (22) with output to the analogue store (50). The signals from the rotation speed sawtooth waveform are passed to a comparator along with those from the multiplier and the output from the comparator forms the injection pulse control signal.

Patent DE-2903711-A1 (DE)
Title: Carrier synchroniser for phase modulated data receiver - analyses signal during setting up procedure to synchronise local carrier generated by counter from pulses
Inventor: BURGER ERICH
IPC: H04L27/227
Filed: 1979-01-31
Abstract: During the setting up procedure for phase shift modulated data transmission, the transmitter carrier (T) is modulated by a constant frequency signal (B), resulting in the data signal (D1). At the receiver a local carrier (TR) is generated by a counter from clock pulses. A zero crossing detector generates pulses (D2) from the signal (D1), some of which coincide with zero crossings of the transmitted carrier (T1). A first timing circuit, with a duration ta slightly less than the carrier half-cycle, is reset by every pulse (D2) so that it only generates an output (Z1) when two consecutive pulses are spaced by ta or longer. The first timer output (Z1) triggers a second timer (Z2) with duration tb such that ta+tb is slightly longer than a carrier half cycle. If a zero crossling pulse (D2) occurs during an output (Z2) of the second timer, a synchronising pulse (R) is generated which resets the counter generating the local carrier (TR).

Title: Warp beaming machine with movable reed - maintained in optimum position by photoelectric warp sheet sensor
Inventor: BOGUCKI-LAND BEGDAN DIPL ING
IPC: D02H13/16
Filed: 1979-05-02
Abstract: Warp beaming machine has the reed mounted between the beam and the warp guide roller nearest the beam in such a way that it can alter its position to maintain a constant orientation with respect to the warp sheet as the dia. of the warp-beam increases. Reed is attached to swinging levers which are mounted on the axis of the guide roller and slowly rotate around the axis during the building of the beam, under the control of a photoelectric warp-sheet position sensor. Placing the reed behind the guide roller separates and reorders the yarns immediately before they are wound, giving better let-off by minimising any possibility of disturbance of the yarns as they are wound.
