Patent DE-3823421-A1 (DE)
Title: The elimination of explosive gas mixtures from large volumes by means of catalytically active surfaces
Inventor: WIESEMES JOHANNES DR
IPC: G21C9/00
Filed: 1988-07-11
Abstract: The explosion-proof elimination of explosive gas mixtures is carried out by means of the recombination of the gas mixtures on catalytically active surfaces which are in a partial volume closed off from the large volume by means of a sieve-like wall material. A thermostatic switch on the sieve-like wall material triggers the release of catalyst poison (paralyser) when the sieve-like wall material has reached approximately 2/3 of the ignition temperature of the gas mixture on hot surfaces. Following significant cooling of the sieve-like wall material, the catalyst poisons are removed from the catalyst surfaces, e.g. by baking out, and filtered out.

Title: Device for preventing the effects of moisture condensation in electrical equipment
Inventor: PRECHTL ROBERT DIPL ING
IPC: H05K7/20
Filed: 1988-08-15
Abstract: Such a device for preventing the effects of moisture condensation is used in electronic equipment, especially in electronic computers, terminals, disk drives, components and the like. In this case, the electronic equipment is arranged in housings, (2), and when a fan (6) is used, the fan (6) is switched on at the same time as the equipment is switched on. In order to prevent malfunction, or even complete destruction, of the electronic equipment, it is proposed to provide at least one measuring means (8) for the external temperature and at least one measuring means (9) for the body temperature of an electronic or electromechanical unit (10), respectively, and to produce a differential value using a differential-value circuit (12), which value, when it exceeds a predetermined threshold value, acts as a switching signal for a circuit breaker (28) which interrupts the power supply (32, 33) of the electronic or electromechanical unit (10), respectively. <IMAGE>

Title: Pipe/flange connection, particularly for hydraulic or pneumatic cylinders
Inventor: DOERRIE KARL-HEINZ DIPL ING
IPC: F16J10/02
Filed: 1988-09-20
Abstract: The invention relates to a hydraulic cylinder with a cylinder tube and an end flange with a guide bore for a piston rod.

Patent DE-3905897-A1 (DE)
Title: Position measuring device
Inventor: SCHOPF REINHOLD DIPL ING
IPC: G01D5/347
Filed: 1989-02-25
Abstract: In such a position measuring device, a carrier member (T1) having a measurement graduation (M1) is provided in a housing (G1) together with a scanning unit (A1) for scanning the measurement graduation (M1). The housing (G1) has a longitudinal slit (L1) which is sealed by two roof-shaped pairs (D1a, D1b) of sealing lips, through which lips a driver (N1) for the scanning unit (A1) engages. Moisture vapours can penetrate into the interior of the housing (G1) owing to unavoidable leaks on the pairs (D1a, D1b) of sealing lips. In order to avoid a disturbing formation of condensates from these moisture vapours on the measurement graduation (M1) and in the scanning unit (A1) as a consequence of temperature fluctuations outside the housing (G1), the housing (G1) is sheathed by means of a thermal insulation unit (E1) in order to exclude thermal interactions between the interior of the housing (G1) and its surroundings (Figure 1). <IMAGE>

Title: Hose-connection fitting for a pressure hose
Inventor: BESCHE ANTON DIPL ING
IPC: F16L33/18
Filed: 1989-03-25
Abstract: The invention relates to a hose-connection fitting for a pressure hose, having a nipple which projects into the interior of the hose end and having a sleeve which coaxially encloses the hose end, presses it radially against the nipple and thus fixes it axially, at least one elastic sealing ring being arranged between the outer wall of the nipple and the inner wall of the hose end. In order to obtain leaktightness, even after long usage and extreme operating conditions, it is proposed that the sealing ring be supported in the direction of the hose and fitting axis, on the one hand, against a flange-like or step-like encircling radial protrusion on the outer wall of the nipple and, on the other hand, against a radial constriction of the sleeve or of an intermediate part which is rigidly connected to the sleeve, and that it be possible to push the nipple and sleeve together relative to one another, by the internal hose pressure, in the direction of the hose and fitting axis to the extent to which the sealing ring can be elastically deformed in said direction. According to a further variant, the function of the sealing rings is assumed by parts of the hose wall.

Title: Flat-bed three=dimensional knitting - using needle control to give structured rows between first and final rows which are joined together
Inventor: REMPP WOLFGANG
IPC: D04B1/22
Filed: 1989-11-10
Abstract: To produce a three-dimensional knitted prod. on a flatbed knitter, such as a virtually seam-free fashioned garment or a hollow core for a plastics body, initially the first row of stitches is formed to pass through or without interruption using the needles of at least one of the two needle beds. This is knitted to the required garment start width and from this, using the needle selection, patterned rows of shaped stitches are developed while at least in zones at the ends of the rows, and/or in sections of the rows away from the ends, the needles are temporarily stopped and restarted. The final row of stitches is at least partially bonded with the first row. ADVANTAGE - The final prod. is in three dimensions, shaped, and has only one seam joining the first and final rows which can be completed by an attachment.
