Patent DE-3821612-C1 (DE)
Title: Electrical switch
IPC: H01H25/06
Filed: 1988-06-27
Granted: 1990-02-08
Abstract: An electrical switch is proposed which is composed mainly of an insulating material housing, an operating device which is mounted on it such that it can be displaced longitudinally and in rotation, a latching device, a switching element which is mounted on the insulating material housing such that it can be displaced longitudinally and in rotation, and a movable contact element which is held on the switching element, as well as contact parts which are held in the insulating material housing such that they cannot move. In this case, in order to keep the wear on the fixed and movable contacts as low as possible, the switching element is assigned to the latching device in such a manner that, in the event of corresponding operation of the operating device, the movement which is transmitted from the latching curve onto the latching element is converted into a lifting movement which, in addition to the operating direction, creates an air gap between the movable contact element assigned to the switching element and the at least one contact part which is held in the insulating material housing such that it cannot move.

Title: High efficiency degassing process for e.g. thermoplastic melts - mixes melt with injected liq. under pressure in extruder, releases pressure to form foam breaks up foam, degasses and spreads into thin film
IPC: B29C48/44
Filed: 1992-09-18
Granted: 1993-08-19
Abstract: In a high efficiency degassing process for thermoplastic melts or similar liquids the melt is added to a single-screw extruder; here its pressure is increased continuously in the direction of movement, back flow is prevented, an entrainment material is injected early in the flow, the melt/entrainment material mix is mixed intensively and homogenised and is then suddenly depressurised and foamed up.

Title: Earth potential unit for deriving benefit from deep seams of pit coal, comprises lance for spraying liquid containing dissolved oxygen into coal to provides lance with potential difference convertible into electric current
Inventor: WINDSANT MICHAEL
IPC: B65F1/14
Filed: 2007-05-03
Granted: 2007-06-07
Abstract: The earth potential unit is employed to derive benefit from seams of pit-coal located very deeply beneath the ground, the traditional mining of which would not be economical. The coal exploitation is effected economically by direct conversion into electricity using several earth potential units, the function of which is on a battery principle. From the earth surface (1) a flow lance (3) is drilled through the earth layer (2) into a pit-coal seam (4), which can be kilometers below ground. The lance sprays a liquid containing dissolved oxygen into the coal, converting the coal into carbon dioxide. The liquid provides the lance with an electrical potential difference which is converted into an electrical current. By coupling together several earth potential units, the electrical voltage is increased.
