Title: Device for heating water, in particular hot water heating boiler
Inventor: VETTER RICHARD
IPC: F28D21/00
Filed: 1981-04-02
Abstract: In order in the case of these devices to achieve a high efficiency and to take far reaching account of safety requirements, one or more heat exchangers which are preferably intended for heating water, but possibly also air for supplying hot air heating systems, are arranged in the flue gas duct of this device. In addition, the burner element of the combustion chamber is assigned a lock, which can be released when the prescribed partial vacuum obtains in the flue gas duct but otherwise prevents the burner element from starting up. For this purpose, there is arranged in the flue gas duct a flap which opens in the event of a partial vacuum and in so doing actuates a switch which connects the burner element or its electric drive motor to a voltage source.

Patent DE-3136920-A1 (DE)
Title: Structural element, consisting of a hollow body, which can be closed in a moisture-proof and airtight manner by walls and rigid or moving closing bodies
Inventor: BECKER OTTO ALFRED DR
IPC: E04B2/74
Filed: 1981-09-17
Abstract: A structural element, consisting of a hollow body, which can be closed in a moisture-proof and airtight manner by walls and rigid or moving closing bodies, in accordance with the main application P 3115760.2. An exemplary embodiment is the use of expanding materials in clamping bodies (structural elements) for forming elastically pretensioned abutments against outside rail sections on curves which are highly stressed by the tangential centrifugal force of rail vehicles. In consequence, it is possible to increase the speed of a train considerably without any risk of derailing. The centrifugal force, which increases with the square of the speed, can be compensated for by pivoting the wagon bodies, which can pivot about a longitudinal axis, in the opposite direction inwards. The risk to goods trains when travelling round the raised outside curves for high-speed trains can also be alleviated by pivoting outwards. For easier understanding, reference is made to the attached figure (1) which relates to the elastically highly prestressed abutments arranged with respect to the rails on the outside of the curves. <IMAGE>

Inventor: PAWLIK DIETER DIPL ING
IPC: H01L21/316
Filed: 1981-10-27
Abstract: In a process for producing oxide layers on substrate wafers (6) consisting of silicon or another oxidisable material in an extremely dry oxygen atmosphere or in an oxygen atmosphere with HCl gas added, the substrate wafers (5, 6) to be oxidised are first placed in a zone (a) at less than 100 DEG C in the high-temperature plant. The oxidising gas, which has a moisture content of less than 0.5 ppm, is introduced into the plant from the loading side (1, 2). After flushing the plant free of moisture, the substrate wafers (5, 6) are transferred to the oxidising zone in the centre of the furnace (4), heated to the oxidising temperature, returned to the starting zone (a) after the oxidation time has elapsed and cooled to temperatures of less than 100 DEG C. The process is used in semiconductor technology for the manufacture of VLSI circuits, in particular in producing thin gate oxides, and in thin-film technology. <IMAGE>

Patent DE-3231968-A1 (DE)
Title: Fire protection door
IPC: E06B5/16
Filed: 1982-08-27
Abstract: In fire protection doors, gates, segments or the like there was the problem that the door casing warped in the event of combustion on one side, as a result of which a gap develops between door casing and door frame, through which gap the hot air, poisonous vapours or the like can escape from the fire space. The invention solves this problem by a heat-insulating retaining element (12) being provided on at least three side faces of the fire protection door (1). The retaining element (12) prevents the conduction of heat between the two door plates (2, 4) and has a heat-insulating pad (13) which is guided in a metal section (14) and distances the metal section (14) at least from one of the door plates (2, 4) in a heat-insulating manner. In addition, at least one of the door plates (2, 4) is movably guided on the retaining element (12), e.g. by a groove guide (8). The movably guided door plate can thus expand freely relative to the retaining element (12) and the other door plate and warping no longer develops. The heat-insulating retaining element (12) can be of the most varied type of design, it also being possible for it to constitute a closed rigid frame in which the door plates are movably guided. <IMAGE>
