Title: Automatic clearance compensation device for drum brakes
Inventor: IIDA OSAMU
IPC: F16D65/56
Filed: 1981-01-12
Abstract: A description is given of an automatic clearance compensation device for drum brakes, in which a motion transmission element or a setting element forming part of this device is manufactured from a shape-memory or thermally deformable alloy. If an excessive amount of heat is generated during a braking operation, the motion transmission or setting element deforms to a predetermined configuration, releasing the engagement between this element and other components and ending the automatic clearance compensation process. In this way, it is possible to prevent overcompensation by the clearance compensation device in the case of excessive heating of the brakes.

Patent DE-3115470-A1 (DE)
Title: Press for compaction or extrusion
Inventor: BRUNOSSON GUNNAR
IPC: B30B11/02
Filed: 1981-04-16
Abstract: The invention relates to a press for compacting or extruding material which is enclosed in a capsule, the capsule being placed in a pressure chamber and surrounded by a heat-insulating, easily deformable material such as talc. The press contains a piston (7) which is introduced into the pressure chamber and generates the pressure which is transmitted from the deformable material to the capsule and compresses the latter. The invention is characterised by the fact that the end of the piston (7) at the pressure chamber end exhibits a part (7a) with a chamfer. An effective seal between the pressure-generating piston (7) and the wall (5) of the pressure chamber is achieved in this manner. The deformable material is prevented from being pressed out between the piston (7) and the surrounding wall (5) of the pressure chamber without using a sealing ring. <IMAGE>

Inventor: HECK GUENTER
IPC: B01D3/14
Filed: 1981-11-04
Abstract: A process for continuous rectification of a liquid mixture containing alcohols, particularly a liquid fermate, employs a plurality of distillation columns to which the liquid mixture is fed in parallel, and which have successively reduced operating pressures and temperatures from an initial one to a final one thereof. The top vapor distillate from the higher-pressure columns supplies driving heat to the sumps of the next successively lower-pressure columns. Direct steam at 130 DEG  C. to 160 DEG  C. is fed to the sump of the column operated at the highest pressure. Direct steam is generated by indirect heat exchange of water with the top vapor withdrawn from the columns, and the resulting direct steam is fed to the sumps of the next-lower-pressure columns. The apparatus can also include a section for the production of absolute alcohol.

Title: Radioclock/quartz clock combination
Inventor: HILBERG WOLFGANG DR ING
IPC: G04G5/00
Filed: 1981-11-07
Abstract: Radioclocks having microprocessors consume so much power that the batteries need to be very large for continuous operation. It is therefore proposed in order to reduce the power loss to split the overall circuitry into two preferably integrated circuit parts in such a way that a low-power part comprises both a quartz clock and some control circuits, and that the second part comprises the circuits which consume power intensely, such as the microprocessor and the analogue receiver circuit, that this part is switched on only for a short time in each case, receives the standard time, correctly sets the quartz clock, computes the next switch-on time, transfers data into the memory of the control circuit, and is then switched off from there.
