Title: Coating welded steel piping with polyethylene - two extruders spirally feed film windings with innermost thickened at welds
Inventor: LANDGRAF HELMUT DIPL PHYS
IPC: F16L13/02
Filed: 1979-11-14
Abstract: Steel piping, made up by butt welding lengths together is covered with thermoplastic, particularly polythene, by extruding film widths which are spirally wrapped round the piping as it is moved past the nozzles; the innermost film touching the piping is an ethylene mixed copolymer to bond to the steel. At each welded joint one of the films is thickened locally by increasing the feed of extrusion. Welds receive thicker covering to provide mechanical protection.

Title: Semiconductor memory - consisting of static induction transistor and superimposed capacitor
Inventor: NISHIZAWA JUN-ICHI PROF
IPC: H01L29/772
Filed: 1979-12-28
Abstract: A semiconductor memory consists of a source zone, a drain zone, and a channel zone to provide a path for the charge carriers. A gate structure surrounds the channel zone in a sandwich fashion. A capacitor has one plate in contact with the drain zone which it overlaps, with an insulating layer sepg. the other plate. Such a semiconductor memory has a greater storage capacity and packing density for compatibility purposes.

Title: Heating system using heat pump - extracts heat from low temp. source at night to heat water forming heat source by day
Inventor: DINKEL HELLMUT
IPC: F25B30/02
Filed: 1980-05-21
Abstract: The heating system for e.g. radiators, using a heat pump, uses a circuit formed by an evaporator, a compressor and a condenser with an expansion valve. This is connected between a low temperature heat source and the radiators. A hot water storage tank has a heat exchanger at one end connected to the evaporator and another heat exchanger at the other end, connected to the condenser. The heat pump is operated so that heat is extracted from the low temperature source during the night to heat the water in the tank. During the day, heat is no longer extracted from the low temperature source, but is extracted from the water in the storage tank. The heat pump then circulates water through the radiators at a still higher temperature level.
Patent DE-3019654-A1 (DE)
Title: Crystalline silicon sheet or strip with columnar structure prodn. - by sintering dried film of slip on reusable refractory inert support
Inventor: GRABMAIER CHRISTA DR
IPC: C30B1/02
Filed: 1980-05-22
Abstract: In the prodn. of crystalline Si sheets or strips with columnar structure, esp. for making solar cells of large area, without melting the material forming the Si structure, Si powder with a granulation of under 1 micron and opt. additives is made into a slip with a binder. The slip is spread into a film on a support and dried and the support is removed. Then the film is sintered on a refractory inert support in a protective gas atmos. below 1430 deg.C, so that a layer of monocrystalline Si grains with a dia. matching the thickness of the film is formed. The novel feature is that a re-usable inert support of a material insensitive to frequent heating and cooling is used. The inert support consists of sintered alumina, Mo, mullite or graphite, esp. with a pyrolytic coating. The process is more economical than previously.

Patent DE-3106973-A1 (DE)
Title: Method for condensing vapour by means of cooling air, and an air-cooled condensation system for carrying out the method
Inventor: SCHREY HANS GEORG DIPL ING
IPC: F28B1/06
Filed: 1981-02-25
Abstract: The invention relates to a method for condensing vapour, in particular water vapour, having inert gas inclusions by means of cooling air, the vapour being split into a plurality of subflows which on the cooling air side are both parallel to one another and one behind another, each subflow of the vapour flowing to the condensate firstly in a direct flow and subsequently in counter flow, and the cooling air for the subflows, flowing to the condensate in counter flow, of the vapour being preheated by the vapour. In order to achieve preheating of the cooling air for the heat exchanger elements, which are connected in a dephlegmatic fashion, so as to avoid the risk of freezing and the formation of frost, without there being a need for an important increase in the heat transfer surface connected in a condensing and dephlegmatic fashion and/or for a change in the ratio between these differently connected heat transfer surfaces, the cooling air for the subflows, flowing to the condensate in counterflow, of the vapour is preheated by the heat which is dissipated during the condensation of a heat carrier located in the closed system and was previously extracted from the vapour in order to evaporate the heat carrier. An air-cooled condensation system intended for carrying out this method is also proposed.
Patent DE-3107859-A1 (DE)
Title: Process for the removal of radioactive constituents
Inventor: GILAK ARMIN DIPL CHEM DR RER N
IPC: G21F9/08
Filed: 1981-03-02
Abstract: Through the increasing use of radionuclides in the fields of industry and medicine, radioactive wastes reach the environment daily, mostly via waste waters. The object therefore was to develop a process which permits a substantial removal and reduction in volume of the radioactive constituents of solutions. It has been established that this aim can be achieved by bringing the radiation solution into contact with acids or bases and concentrating the mixture by means of distillation. After evaporation, the liquid forms a residue, which contains all the radioactive substances. This residue is either removed from the distillation apparatus or ashed by means of relatively high temperature, the radioactive gases resulting thereby being trapped by suitable filters. The total radioactive residue and/or the radioactive filter elements can then be stored under radiation-proof conditions, until the radiation has reduced to an insignificant level. The concentration of the radioactive liquid should be carried out in a vessel whose temperature can be controlled, in which the liquid to be distilled is brought to boiling and the resulting vapours are either condensed by means of a condenser or are sucked into a condenser arranged downstream by means of a pump generating a vacuum in the vessel. In this method of operation, it has proved to be advantageous to absorb the possibly radioactive gases, which cannot be condensed during the condensation, by means of appropriate filter elements. The filter element can be provided directly prior to the vacuum-generating pump. The condensed liquid can be safely discharged either via an anion exchanger or, where possible, as a non-radioactive liquid.

Patent DE-3127553-A1 (DE)
Title: Folding bearing
Inventor: KUNZ WOLFGANG ING GRAD
IPC: B65H16/06
Filed: 1981-07-11
Abstract: A folding bearing (1) having a receiver (8) for a shaft, which can be inserted in a positive-locking manner, or a winding bar or the like for winding or unwinding webs of material has a hand wheel (10) which also rotates and can be pivoted about a pivot axle (11), running transversely to the axis of rotation or carrier shaft (4) of the folding bearing (1), from the region of the shaft receiver (8) into an opening position. In the region of the closing position, the hand wheel (10) has a snap-in closure. Acting on the hand wheel (10) with spacing from its pivot bearing axle (11) is a mechanical adjusting device (15), for example an operating cylinder (16) with a claw (17), such that an opening and closing movement of the hand wheel (10) by machine is made possible. This is advantageous above all under restricted conditions or in an arrangement of the folding bearing in the hazardous region of further machine parts. Furthermore, controlling the opening and closing movement is thus made possible with the aid of a switch (30) which can control these movements as a function of the rotary position (Figure 1). The actuation of the adjusting device (15) by the switch (3a) can preferably take place in a delayed manner in order to avoid undesired response of the adjusting device when the reel passes over the rotary removal position. <IMAGE>
