Patent DE-2952636-A1 (DE)
Title: Power chuck control system - includes double lobe cam actuating two switches connected to programmer
Inventor: SCHUBERT LOTHAR DIPL ING
IPC: B23Q5/58
Filed: 1979-12-28
Abstract: The safety of operating a power-acuated chuck of a lathe is ensured by eliminating faulty action due to operator's error. The insertion of the twin-lobe control cam controls switches connected by a common plunger. The switches are connected to the memory of a programmer and are set w.r.t. each other with an offset in relation to the plunger. When the plunger runs onto a lobe of a cam by closing the chuck, the operator cannot start the machine and this provides a warning that an incorrect cam is inserted for the range of intended operations.

Title: Hydropneumatic heat pump unit - uses fluid to transfer expansion energy to expansion side from gas circuit
Inventor: RABIEN PETER
IPC: F25B30/00

Title: Gas-discharge electron gun using cold cathode - where anode ring has internal profile increasing power output of electron beam, which is used for metal processing etc. (SE 17.5.82)
Inventor: UDRIS JAN JANOVIC
IPC: H01J37/077
Filed: 1980-10-13
Abstract: The gun has a cathode with a bottom, emitting, concave surface located above an anode ring. The bore of the anode ring has a vertical convex profile with a region (I) opposite the negative glow plasma. Surface region (I) has a hole leading to a channel used to measure the gas pressure. Region (I) tapers downwards so the focal point of the electron beam is kept at a constant height. At the lower end of region (I) is a ring channel for feeding gas into the discharge zone, and a bush surrounding the focal point of the beam. The bore of the bush is larger than the dia. of the beam at the focal point of the latter. The distance of the upper part of the bush from the ring channel is smaller than the average free path length of the gas molecules travelling towards the cathode. Increased power output and improved stability of the gas discharge are obtd.

Patent DE-3102077-A1 (DE)
Title: Duplicating set
Inventor: FISCHER WERNER
IPC: B41M5/124
Filed: 1981-01-23
Abstract: The invention is based on a duplicating set (1) made of chemical autocopying papers having two reaction components of an autocopying system to produce a printed image when pressure is exerted. In the case of two layers of paper (3, 4, 5) arranged one above the other, the side (6) facing another layer (2, 3, 4) in each case has a coating (7) with a first component of the autocopying system in a form which is released under pressure loading, is flowable, and can be transferred to the opposite layer of paper (2, 3, 4). The side (8) of the other layer (2, 3, 4) facing the opposite first layer (3, 4, 5) has a coating (9) of the second component for producing the printing image on this side (8). These duplicating sets can only be used on one side. In order to allow two-sided use, it is proposed that removable intermediate layers (11) of duplicating papers are provided which have, on a side (12) facing the first component coating (7), a coating (13) with the second component in a form which is released under pressure loading, is flowable, and can be transferred to the opposite side (6) of the adjacent layer of paper (3, 4, 5). <IMAGE>

Title: Multi-purpose ice axe for mountaineers
Inventor: KRIEGER WERNER
IPC: B25D7/00
Filed: 1981-04-28
Abstract: Multi-purpose ice axe for mountaineers (technical climbing implement). Current ice axes are made exclusively of a rigid shaft and consequently cannot be altered and cannot be used in all situations. The solution consists in the fact that the shaft of the ice axe consists of several variable parts and can thus be turned into the following implements. In particular: ice axe, short-shafted ice axe, ice gouge, ice piton, emergency snow anchor. The multi-purpose ice axe is used to ensure that some implements are still available to the mountaineer who has got into difficulties in the mountains due to the loss of the rest of his equipment, as a result of which he can escape to relatively safe terrain if the ice axe is used properly.
