Title: Angular transmission drive head - with bevel rollers contacting square shaft sides, useful in rolling mills
Inventor: ZOEBERLEIN DIETER ING GRAD
IPC: B21B38/10
Filed: 1978-09-01
Abstract: A drive head for use, for example for the remote indication of the angular movement of the screwdown spindle on rolling mills, converts a rotary and axial motion of a shaft in a pure rotary motion of a square shaft. The side faces of this shaft are in contact with the conical clanks of four rollers, two of which have spring loaded bearings. The rollers are mounted in two shafts of the angle transducer. This ensures freedom from backlash in the transmission of the screwdown operation. It compensates for varying manufacturing tolerances of the square shafts and for wear without any necessity for readjustment.

A battery/mains unit provides power for the indicators and hook-switch opto-coupler. Opto-couplers are used to make the test-set immune to interference voltages induced in the line. A cut-out (s) opens if excessive loop current flows and the opto-couplers are protected by non-linear circuits such as Zener diodes.
Patent DE-2913124-A1 (DE)
Inventor: KOENIG HELMUT DR ING
IPC: B61L17/00
Filed: 1979-04-02
Abstract: During gravity-shunting, it happens occasionally that individual sections are not supposed to, or must not, run away over the hump. These vehicles are to be separated out during the gravity-shunting process by briefly interrupting the gravity-shunting process when the section to be separated out is located just in front of the hump. The invention consists in a method for braking to a stop sections which have been separated out by step-by-step reduction of the admissible push-back speed when moving such sections onto the hump. The braking to a stop is then to be initiated when the respective section running in front of the section to be stopped passes the hump.

Title: Automobile trafficator and parking light steering column switch - prevents erroneous energisation of parking light by requiring deliberate manoeuvre of switch lever
Inventor: MILLES ALBERT GEORG
IPC: B60Q1/14
Filed: 1980-02-05
Abstract: The switch is operated by a switch lever pivoting in at least one plane and with two bridging contacts cooperating with corresp. fixed contacts in the switch socket. The lever has two switch positions corresponding to respective direction indications either side of a central rest position with the parking circuit, causing one or other trafficator light to be permanently energised, selected by moving the lever in to one of the switch positions and then further tipping it to allow a slider carrying the U-shaped bridging contact for the parking circuit to move with the switch block to contact the respective contacts. The switch prevents the parking light circuit from being energised by mistake and automatically disconnects it by manual or automatic cancellation of the trafficators.
