Title: Rotation speed measurement device - uses opposed pulsed laser beams in coiled optical fibre and different rotation cycle compensation
Inventor: BOEHM MANFRED DR ING
IPC: G01P3/36
Filed: 1979-04-28
Abstract: A rotational speed measurer has a coiled optical fibre carrying two partial beams from a laser light source in opposite directions. The beams are superimposed after passing through the fibre and fed to an optoelectrical transducer. The conversion of the superimposed beams into rotation speed is performed simply. The use of pulsed light signals prevents cross coupling from laser to transducer and the accuracy is independent of the fibre characteristics. A pulsed laser, is used and the beams pass repeatedly through the fibre. They are partially decoupled after each rotation and fed to the transducer whose output is sensed after each beam rotation. The different beam rotational cycle effect on the partial beam signals is compensated by weighting the signals. The speed is derived from the signal envelope frequency.

Title: Combined hydrodynamic and friction brake system for heavy lorry - has electronic adjuster to relate hydrodynamic input to observed deceleration of drive shaft
Inventor: SAUKA KLAUS ING GRAD
IPC: B60T13/58
Filed: 1979-05-10
Abstract: The braking system combines the effects of separate friction and hydraulic brakes to control the rear drive wheels sensors monitoring drive shaft deceleration to govern hydraulic brake input and prevent wheel lock. The hydraulic brake effects are adjusted by modifying the capacity i.e. quantity of brake fluid with an electronic adjuster comparing the read and desired values of the hydraulic brake rotor velocity. An electronic rev counter on the drive shaft transmits the real valve to a difference detector which in turn feeds an error signal to the adjuster. The desired value may be set and modified by means of a sliding resistance operated by a lever.

Title: Non-consumable electrode welding head - with oscillating longitudinal and vertical drive for electrodes flanking filler wire
Inventor: GRININ VLADIMIR VASILEVIC
IPC: B23K9/30
Filed: 1979-11-09
Abstract: A welding system is based on a welding head with a central filler wire, flanked by two slightly inclined non-consumable electrodes which are oscillated by a bevel gear drive. The welding head is mounted on a slide which is moved by a rack-and-pinion drive longitudinally and has a separate feedscrew drive for its vertical motion.

Title: Counter with lockable reset knob - release key raising reset knob place spring above longitudinal motion stop
Inventor: ZIELKE ALFRED
IPC: G06M1/28
Filed: 1980-07-30
Abstract: A counter mechanism with a reset knob blocked by a plate spring resting against a stop has a reset key which removes the spring from the stop and hence clears the reset knob. The counter can thus operate with a blocked or free reset knob. This is achieved without the special preparation of a reset key. The reset key, consisting of an arm and short web is made as a removable part of the reset knob. When in the engaged stage, the key holds the plate spring permanently out of engagement with the stop. When the arm is inserted into the housing it engages a cut-away section of the plate soring so as to raise it from the stop and allow it to slide longitudinally.
