Title: Process for the production of thin-walled welded pipes with a straight seam
Inventor: SHEVAKIN JURY F
IPC: B23K9/025
Filed: 1981-11-27
Abstract: The invention relates to the sector of the production of thin-walled welded pipes. The process according to the invention is characterised in that, first, a tubular billet having a gap between the edges which is measured in mm and which is 1/500 to 1/30 of the ratio of the pipe diameter to the wall thickness is formed from an initial strip by the rolling of a forming rolling mill. Then, the tubular billet is welded under inert gas by means of an arc with a non-fusible electrode. Thus, the welding speed and the welding-current value are selected according to the conditions for heat generation in the welding zone which is sufficient for eliminating the gap between the edges as a result of a thermal expansion of the material of the tubular billet and for the formation of a welded joint. The process is preferably provided for the production of thin-walled pipes used for heat-exchange appliances and consisting of nonferrous metals.

Patent DE-3207244-A1 (DE)
Inventor: KANTNER ALEXANDER DR ING
IPC: F25B15/00
Filed: 1982-02-25
Abstract: In known sorption heat pumps which comprise a separator (1) and a condensor (2), the refrigerating fluid vapor is supplied after condensation to the condensor (2), to the evaporator by passing through an expansion valve. Sometimes the evaporator is not capable of evaporating all the refrigerating fluid. As a result, the evaporator is field with refrigerating fluid in a liquid state, hence interrupting the operation of the heat pump. To avoid such a disadvantage, the separator (1) and the condensor (2) form together a column (3). Thus, it is possible to bring back the condensate of refrigerating fluid unused to the separator, when the pressure is equal in the condensor and in the separator, without requiring an additional motor force.

Title: Optical scanning system for a copier having a variable reproduction ratio
Inventor: MOLDENHAUER MARTIN
IPC: G03G15/041
Filed: 1982-05-11
Abstract: The invention relates to an optical scanning system for a preferably electrophotographic copier having a variable reproduction ratio, which is equipped with a mirror lens. The aim of the invention is to eliminate existing disadvantages, such as the multiple use of mirror lenses, the changing of the transport motion between scanner and original in the event of a change in scale, large scanning and deflecting mirrors, unfavourable beam incidence, complicated cams for the movement of the mirror lens, or narrow focal length tolerances at the mirror lens. It is the object of the invention to apply the scanning system in order to apply the optical relationships in the best possible way during a change of scale. According to the invention, the object is achieved when the optical axis of the mirror lens has an angle relative to the glass bearing surface that can be changed in accordance with the reduction ratio, the mirror lens can be displaced in the event of a change of scale along its image-side main beam by a distance varying in accordance with the reduction ratio, and the angle made by the image-side main beam relative to the glass bearing surface remains constant for all changes in scale which occur. <IMAGE>

Arranged in these recesses are supporting rings (6, 7, 8) which consist of a material which is still deformable but is more solid than the sealing ring (5) and is used for supporting the edges of the sealing ring (5). <IMAGE>
Patent DE-3233286-A1 (DE)
Title: Rotary piston engine
Inventor: NULL VICTOR GARY
IPC: F01C11/00
Filed: 1982-09-08
Abstract: A rotary internal combustion engine of this type has a rotor eccentrically mounted in a circular fixed housing with a sliding piston attached radially. They serve as vanes for driving the rotor. Also attached to this rotor are two close-fitting rotating discs, each of which form a seal for the rotor on both sides of the fixed housing and at the same time maintain the position for the rotor and the piston. The rotor additionally has fresh-air pistons let into it, which bring additional fresh air into the combustion spaces after the first combustion and thus facilitate the running of the rotor and the internal cooling of the engine. The two discs on both sides of the rotor have through-openings leading to the rotor, allowing extra fresh air to be let into the openings of the fresh-air pistons. The engine also has the characteristic of enriching the unburnt hydrocarbons in the exhaust gases once more with fresh air and burning them a second time.

Title: Integral melting conductor for electrical fuses
Inventor: REINHOLD ULLRICH DR
IPC: H01H85/055
Filed: 1982-10-28
Abstract: The invention relates to an integral melting conductor for electrical fuses having at least one deposit of effective material in a groove, and constriction points which reduce the cross-section. The aim of the invention is to create a melting conductor which has low energy losses, is resistant to ageing, has a fixed characteristic and can be produced in a technologically advantageous manner. A melting conductor has been developed which melts through quickly at temperatures which are only slightly above the melting point of the effective material, as a result of the deliberate generation of flows in the fluid effective material and the utilisation of precipitation processes, and interrupts the current flow in that a local region of the carrier material web which is half covered with effective material is dissolved at right angles to the surface and simultaneously over the entire width of the web. Such melting conductors are used especially in low-voltage and high-power fuses. <IMAGE>
