Title: Self-cleaning filter for a gaseous media compact system with dust-entry superelevation, process and implementation therefor
Inventor: SCHMID RUDOLF MARTIN DIPL ING
IPC: F02C7/052
Filed: 1987-03-30
Abstract: With a combined feed and exhaust air fan which is driven by a centripetal turbine, seated on the same shaft, and which is impinged by a front take-off stage of the axial compressor of the gas turbine, advantages result with respect to automatic control of speed of rotation, maximum air-flow rate, automatic run-up and start with the gas turbine. The dust-entry superelevation described in the main patent is put into effect in a compact air-intake filter system which provides the air-intake orifice at the highest point and the air conduction leading vertically downwards in the direction of fall of the dust particles. This process is optimum with respect to the dust-intake load, the dust separation and prevention of reentry of the dust. Because of the easily implementable sequential arrangement of the module - see Fig. 11 - a double arrangement is shown - the volume of the filter system is still further reduced, without the advantages according to the invention being impaired in the separation. <IMAGE>

Patent DE-3741547-A1 (DE)
Title: Non-return valve for pipes
Inventor: MEYLER JAMES FRANCIS
IPC: F16K15/04
Filed: 1987-12-08
Abstract: In a non-return ball valve for pipes, the stop seat (13) for the ball (5) is formed from a thickly applied elastomer coating (11). The elastomer material compensates tolerance deviations between the ball (5) and the stop seat (13) to the greatest extent and guarantees a good sealing effect of the valve when the ball (5) is in the closure position. Owing to the extension of the coating (11) beyond a spacer ring (9) on the lower surface (8) of the lower connection flange (3), the insertion of an additional seal between a pipe flange (7) and the lower connection flange (3) can be dispensed with. <IMAGE>

Title: Combined air-conditioning/heating system with independent current generation
Inventor: GEIER-HENNINGER KURT
IPC: F01N5/02
Filed: 1988-04-06
Abstract: The combination opens up many production possibilities which may be utilised by the ventilation engineer and also by the heating specialist. The variety of applications, including independent current generation, full utilistion of waste heat from cooling water and hot waste gases of the drive assembly, conversion of the production heat into hot air or alternatively hot water, with steam generation as desired, can satisfy any wishes that a cost-conscious operator may have. Independence in all areas makes this combination possible. The existing power-station network can be provided in the event of failure of the drive as an emergency power circuit. The primary-energy use affords a saving of 38 % over traditional power consumption. If a heat-pump capacity of factor 4 is calculated, which is the case here, then when the combined air-conditioning/heating system is in operation an overall saving of 50 % compared with conventional installations can be expected.

Patent DE-3831839-A1 (DE)
Inventor: VEITH GUSTAV DR PHIL
IPC: H04B10/29
Filed: 1988-09-20
Abstract: An optical module is used for communication over optical waveguides. To couples laser light to or from the optical waveguide (3) with as little loss as possible, the laser diode (2) must be precisely aligned with respect to the core region (22) of the end face (14) of the optical waveguide. In conventional modules, this requires costly and complicated mechanical couplers, which nevertheless do not have the necessary long-term stability. To solve the problem of how to provide a low-cost laser-to-fiber coupling which exhibits long-term stability, the optical module (1) is provided with a control facility (16, 17, 18) which controls the coupling of light on the basis of measurements of the differences in reflection factor between the core region (22) and the cladding region (23) of the end face of the optical waveguide (3). For this measurement and control, use can be made of low-priced components employed in CD players.

Filed: 1989-04-12
Abstract: The relay has a flat iron core which forms the middle yoke (8) in an E-shaped yoke with its three yoke branches (10, 8, 9)  extending over the whole length of the coil (7). A permanent magnet piece (21) whose field is extended into adjacent pole shoes (19, 20), forms a part of a vertically guided and shiftable mono-stable electromagnetic relay anchor. Dependent on the direction of the electromagnetic flow, the lower or the upper yoke would prevail in attracting the anchor assembly. A T-shaped insulator block (1) has a groove of the same width as the lower yoke (9) of the relay coil (7) in which the yoke is firmly held. On both sides of the double T insulating block space (23,24) is available for the contact springs and contactors (34, 36, etc). The upper contactors are directly spotwelded to the relay leads (29) whereas the lower contactors are spotwelded to the relay spring blades (34). A lifting plate (31), linked to the monostable vertically shiftable anchor system, imparts the switch movement to the contact blade thus making and breaking contactors. The leads (29) are directly soldered into a wiring board. ADVANTAGE - Compact and easy to manufacture, has adequate displacement force to provide good contact pressure.
