Title: Current control circuit for lamp etc. - has two-way counter determining required effective current through load and coupled to RC circuit
Inventor: DUGGE KARL-WILHELM DIPL ING
IPC: H02M5/257
Filed: 1974-08-21
Abstract: The current control circuit for an electric load, such as a lamp, has a triac connecting the load to the supply during every half-period of the supply voltage via a RC element and a di-ac. A two-way binary counter (5), with staged resistors (R3 etc.) connected to its ouputs, is coupled to the RC element capacitor (C1). The binary counter gives the required value of the effective current through the load (L) in digital form. The counter is coupled to a signal generator (22) controlled by two sensor surfaces (B1, B2), which accordingly cause it to produce either positive or negative pulses that increase or reduce the counter contents.
Patent DE-2443689-A1 (DE)
Title: Roller yoke adjustment on hot rolling mill - has twin screw spindles with radial wedge release unit
Inventor: PASSONI TERESIO
IPC: B21B31/30
Filed: 1974-09-12
Abstract: Two rollers carried by U-shaped bearing yokes are placed inside a vertical frame. The upper yoke is attached to the top member of the main frame. Two screw spindles located in that top frame member are acting on the upper roller yoke so that the axial roller distance can be adjusted. Excessive forces set up by the rolling process, sometimes cause the adjustment spindles to seize up. To free the spindles in such a case, a number of wedge shaped sectors, held together by a circular retainer ring, are placed between each spindle end and the roller yoke. One end of the ring passes through a slot in the other end. Both ends are hook shaped so that two locking plates with toggle action placed between them keep the retainer ring closed. When the locking plates are removed the ring opens, thus the wedge shaped sectors move radially outwards and release the spindles.

Title: Linings for metal sintering or condensn plants - coated so that deposits of metal or dust can easily be removed
Inventor: JUERGENS WALTER DR ING
IPC: F27D25/00
Filed: 1975-01-22
Abstract: Metal recovery processes, esp. those employing condensn. plants together with sintering plants, or utilizing only condensn. plants, the novelty being that the condenser is lined with refractory bricks which are provided with a product exerting a sepg. effect, i.e. a coating reducing the adhesion of other materials to the refractory bricks.
