Title: Procedure for electricity generation - using industrial waste heat and height difference for working-fluid closed cycle to overcome pressure drop
Inventor: VELDUNG ERWIN
IPC: F01K27/00
Filed: 1979-10-30
Abstract: The procedure for utilising industrial waste-heat to generate electric power is based on the availability of a source of waste-heat at temps. between +90 and +150 deg.C, and of a land feature between 20 and 400 m high. A heat exchanger (3) at the base of the feature uses the waste-heat to evaporate a working fluid. The vapour rises along a pipe (5), possibly heated, to drive a prime mover (6) coupled to a generator (7). It then passes through a water (8)-cooled condenser (1) at the feature's top into a return line (2), the static head overcoming the evaporator pressure-drop.

Title: Evaporator defrosting system for heat pump - has flow periodically controlled by return line to increase saturation pressure and condensation
Inventor: HEIMBACH PAUL DIPL ING
IPC: F25B30/04
Filed: 1980-04-29
Abstract: The heating system with a heat pump has two circuits, one circulating a mixture of water and ammonia the other circulating water, so as to heat two different systems. The whole of the ammonia solution is passed through a by-pass line connected between an expansion valve and the feed end of the coil of an evaporator, which forms one heating device. The flow through this line and the vapour return line to the evaporator is so determined that a saturation pressure reached inside the evaporator causes the vapour to condense. This occurs at temperatures between 3 and 10 deg.C. The pressure maintained inside the evaporator is less than the pressure inside the condenser which precedes it, and greater than that of the absorber. The flow is controlled by electromagnetic valves which are operated at fixed predetermined times.

Patent DE-3108221-A1 (DE)
Title: Device and process for producing adhesion bonded plastic and metal profiles
Inventor: MAYER GERT
IPC: B29C65/46
Filed: 1981-03-05
Abstract: The above-described invention serves predominantly for producing automobile trim strips and impact bars without injection moulded-on end regions, in which a PVC profile, drawn over a stainless steel profile provided with adhesive, is to be introduced into an MF induction coil by means of movable plastic cassettes, heated in a contact-free manner without material transfer and the two profiles are to be bonded firmly to one another, continuously as far as the end regions, by activating the adhesive. In the case of induction coils which are, for example, designed in a round, rectangular or other shape, with cooled coil windings wound uniformly with a spacing, the respective end regions are not heated sufficiently to achieve perfect adhesive bonding even in this region. The problem of the heating, taking place uniformly as far as the end regions, of the stainless steel profile which is formed into plastic and inserted in a plastic cassette covered with hard chromium was solved in that an MF induction coil designed in accordance with Faraday's induction law is provided with coil windings which are wound not in the conventional manner formed uniformly with a spacing, but rather, at the critical regions of the strips or bars to be adhesively bonded, as closely together as possible and insulated with respect to one another. <IMAGE>
