Patent DE-2922674-A1 (DE)
Inventor: STUCKMANN DIETER
IPC: E02D17/08
Filed: 1979-06-02
Abstract: Such a shield is used for driving cavities and has profiled driving cutters (10, 11) which are guided on a follow-up supporting frame (12) and can be advanced by hydraulic jacks (15). A driving machine (22) mounted in the supporting frame (12) is equipped with a cutting arm (23). In contrast to the driving cutters (10), the floor cutters (11) are tapered in their width; uncovered gap spaces (25) are produced between the floor cutters (11) and allow soil material which has forced its way in to escape through them rearwards into the shield space when the supporting frame can escape rear into the shield space when the supporting frame (12) is drawn up. This prevents the ingress of soil material into the space below a cover (20) of the supporting frame (12) and its build-up and compaction, which leads to operating trouble. <IMAGE>

Title: Light fitting with rotary cover - uses leaf springs, distributed over periphery of housing wall, cooperating with latching lugs and recesses
Inventor: THIELE KARL-HEINZ
IPC: F21V17/14
Filed: 1980-04-15
Abstract: The securing of the light fitting cover is carried out by a rotation-symmetrical, shouldered edge during assembly. Movable leaf springs are mounted inside on the housing wall and distributed over its periphery in a plane parallel to an ideal dividing plane, the springs being vertical to this plane. They have a front abutting surface with an adjacent latching lug, or depression. Outside the cover edge, in the angular spacing of the leaf springs, are distributed latching depressions, or lugs, with abutting surfaces. In order to close the light fitting the springs lock at the latching lugs, or depressions, during corresp. rotary motion of the cover. Thus the cover edge section, at right angles to the housing wall, abuts the latter, while the connection can be released under corresp. pressure in the opposite direction.

Title: Washing machine with double-walled condenser lid - which prevents escape of steam to atmosphere
Inventor: BARTH ERICH
IPC: D06F37/28
Filed: 1980-06-27
Abstract: A washing machine has a top, fluid-tight lid of hollow construction which functions as a condenser for steam and lather from the wash liquor. The outlet to atmos. on the upper side of the lid is diametrically opposite the steam inlet on the lower side of the lid, and a series of baffles provides a labyrinthine path between the two of considerable length. The outlet is restricted to a fraction of the size of the inlet by a flap valve which limits the steam throughflow, but opens to allow the rapid entrance of air into the vessel when the internal pressure falls. This construction provides constant pressure balance within the vessel whilst preventing the escape of large volumes of steam to atmosphere.

Patent DE-3103878-A1 (DE)
Title: Voltage-dependent resistor
Inventor: ZURMUEHL KONRAD DR
IPC: H01C7/112
Filed: 1981-02-05
Abstract: The invention relates to a voltage-dependent resistor having high n-value composed of a sintering material which essentially consists of zinc oxide and added dopants and is characterised in that an oxygen-donating substance is added to the sintering material so that a zinc oxide decomposition is largely avoided during the sintering operation. The oxygen-donating substance is blended as homogeneously as possible with the sintering material so that the available oxygen is able to satisfy all the zinc ions as far as possible during the decomposition as a consequence of the heating up during sintering, i.e. as a result of the high affinity between zinc and oxygen as many lattice faults as possible can be occupied by oxygen as a result of which the added dopants are displaced and accumulate at the grain boundaries of the zinc oxide. Very high n-values can be achieved while maintaining the C-value without an expensive process being necessary for the purpose. The spread in the C-values due to production is reduced. In addition, a less critical sintering control is possible as a result of the invention, i.e. the varistor property no longer depends critically on maintaining certain sintering parameters.
