Patent DE-2629019-A1 (DE)
Title: Colour TV CRT deflection system - simplifies winding for pin cushion and barrel control with ferrite ring core
Inventor: BROWN PATRICK
IPC: H01J29/76
Filed: 1976-06-29
Abstract: The deflection system for colour picture tube of the shadow mask type uses toroidal coils wound by simple means and eliminates the necessity for ferrite correction elements. The ring core is then without grooves which must be aligned w.r.t. the electron gun, and the main toroidal coils are wound around the ring. The vertical deflection coils include more turns, and thus reduce the power required for the vertical deflection. The main winding H and the auxiliary coils H1/H2 are wrapped on the ring core by a toroidal winder, the auxiliary coils controlling the field in the front and rear of the core. A similar arrangement is used for the vertical deflection, and the auxiliary coils can be made by the printed circuit technique for a coil fitted on the inside of the ferrite ring core.

Title: Transistorised switching stage short circuit protection - has measuring resistor between output stage emitter and supply whose voltage drop excites evaluation circuit initiating disconnection
Inventor: WAGNER KARL ING GRAD
IPC: H03K17/082
Filed: 1976-07-20
Abstract: The protective circuit is intended for several transistor stages which in addition to central protection, are given also a current limiting. A measuring resistor (R2) is provided between the output stage (T2) emitter and supply voltage (-Uv). A reference Zener diode (G3) is in parallel with the output stage base and with the supply voltage. A further measuring resistor (RS) is in series with the Zener diode (G3) whose voltage drop, exceeding a certain threshold (G2) excites an evaluation circuit (OP) which initiates a delayed short circuit disconnection. A diode (G1) decouples further circuits.

Title: Hydromechanical vehicle transmission with regenerative braking - has hydraulic and mechanical drive on flywheel and differential
Inventor: HEINSCHER KLAUS DIPL ING
IPC: B60K6/10
Filed: 1976-08-26
Abstract: The vehicle engine (1) is coupled to a hydraulic transmission (2) and a mechanical system (3), with the latter driving a flywheel (5) via a hydraulic motor (4).

Title: Drilled anchorage for pile reinforcement bar - has end of bar enclosed in wedge shaped former to compress filling material against drilled hole wall
Inventor: BORSDORF HEINZ DIPL ING
IPC: E02D5/80
Filed: 1976-11-19
