Title: Coherent transceiver unit for the millimetre wavelength range, in particular a radar device
Inventor: BARTH HELMUT DIPL ING
IPC: G01S7/288
Filed: 1981-11-07
Abstract: Coherent transceiver unit for the millimetre wavelength range, in particular a radar device, in which on the one hand a local oscillator signal with the frequency fLO is derived from a control oscillator (Os1) and fed to a receiving mixer (M), and on the other hand a synchronisation signal is derived which synchronises a second oscillator (Os2) on a modulation sideband, where the second oscillator (Os2) determines the transmission frequency (fO). An arrangement of this type is also to be used for the frequency range above 60 GHz. For this purpose, the fundamental frequency of the control oscillator (Os1) is selected as 1/2  . fLO, the second oscillator (Os2) generates the frequency 1/2  . fO and is modulated with half of the first intermediate frequency, i.e. 1/2  . fZF, of the transceiver unit, the second oscillator (Os2) is synchronised by the fundamental frequency 1/2  . fLO of the control oscillator (Os1) on a sideband with the frequency 1/2  . (FO +/- fZF), and the second oscillator (Os2) synchronises a harmonic oscillator (Os3), which emits the transmission frequency fO as the first harmonic, on its fundamental frequency 1/2  . fO. <IMAGE>

Patent DE-3200008-A1 (DE)
Title: Method and device for testing metallic samples for examination by spectral analysis
Inventor: HENNING NORBERT
IPC: G01N21/67
Filed: 1982-01-02
Abstract: A satisfactory examination of metallic samples by spectral analysis requires them to have a crack-free and blowhole-free test surface at which a spark spectrum is initiated. After reaching the solidification temperature, the test surface of the samples is tested for uniform infrared emission, which indicates, regardless of the thickness of any scale layer, whether the test surface is crack-free and blowhole-free. This is done either by recording a thermogram of the emitting test surface and evaluating it visually or optoelectronically or by recording an infrared image using an infrared camera and comparing it with a stored infrared image of a standard sample.

Inventor: WIESER RUDOLF DR
IPC: F01K23/06
Filed: 1982-01-30
Abstract: It is known for the thermal efficiency of a thermal power station block to be increased by combining a gas turbine and a steam turbine. The invention relates to such a combined gas-turbine (hot-air-turbine)/steam-turbine system, in which the atmospherically heated steam generator is connected downstream from the hot-air turbine and in which both the medium of the hot-air turbine as well as the steam generator are heated by means of coal dust. The air heaters of the hot-air turbine are arranged in specific auxiliary chambers of the steam-generator combustion chamber and the heating thereof can be matched to the operating requirements. In the event of disturbances on the gas-turbine side, it is also possible to keep the steam generator in operation and to interrupt completely the heating of the air heaters. The proposal is even suitable for the reequipment of existing steam blocks in order to increase their thermal efficiency. <IMAGE>

Title: Electropneumatic servo valve
Inventor: GOEDECKE WOLF-DIETER DR ING
IPC: F16K31/08
Filed: 1982-05-05
Abstract: The subject matter of the invention is an electropneumatic servo valve consisting of a pilot-control stage (1) and a main valve stage (2). The pilot-control stage (1) contains a baffle-plate system (7, 8, 9, 10) which can be controlled by means of electrical signals and interacts with a nozzle (22) in the main valve stage (2). In order to obtain an exact setting of a desired working point, the devices of the pilot-control stage (1) and those of the main valve stage (2) are accommodated in separate housings (3, 4) with fine-pitch threads (24, 25) as connecting means. The setting of the working point, that is, the distance between baffle plate (9) and nozzle (22), is effected by sensitive screwing of the pilot-control stage (1) into the main valve stage (2), and the working point is correctly set when a measurable change at the working outlet (A) of the main valve stage (2) is obtained. This position is fixed by a screw locking means (32). In addition, on account of the connection by means of fine-pitch threads (24, 25), the pilot-control stage (1) and the main valve stage (2) can be exchanged. Servo valves of this type are used in the control of pneumatic drive systems. <IMAGE>

Title: Method and device for de-oiling bilge water
Inventor: BURKARD DIETRICH ING GRAD
IPC: B63B17/00
Filed: 1982-06-12
Abstract: As the oily bilge water on ships also contains cleaning agents which have an emulsifying effect and impede separation of the oil from the water, the use of a specifically light, rapidly separating cold cleaner is envisaged, the surface-active components of which are enriched in the oil. The bilge water is collected in a calming chamber, from which, after sufficient settling time, the water phase is first drawn off and delivered via a de-oiling installation. The device for de-oiling the bilge water comprises among other things pumps and a pre-separating tank as well as an electric circuit for the pumps, which guarantees that the separating and calming time between the pumping processes is observed.

Patent DE-3237216-A1 (DE)
Title: Chimney cowl for central heating installations with atomising burners
IPC: F23L17/08
Filed: 1982-10-07
Abstract: Modern central heating installations with atomising burners are designed for an optimal working or operating point, in order that the heating installation achieves as high a degree of efficiency as possible. This presupposes that the draught conditions in the chimney are as constant as possible, and specifically independent of external wind influences, in particular their strength or their direction of incidence, which flow around the chimney mouth. The chimney cowl serves this purpose. The pipe (1), which projects beyond the masonry chimney, supports an external heat insulation (2) which is delimited by a cone envelope (3) with concave generatrices. Also provided is an external pyramid-shaped casing (11) consisting of plane surfaces (12) which on the circumference side adjoin one another directly and form a closed casing. Pipe (1) and casing (11) are at a distance from one another so that an annular throughflow channel (13) is formed, which has different throughflow cross-sections parallel to the axis of the chimney. Tests in a wind tunnel have shown that, even with extreme wind loading, specifically with regard to both its size and its direction of incidence, it is possible by using this chimney cowl to maintain constant draught conditions to an exceptionally great extent in the chimney. <IMAGE>

Title: Hydraulic flow-control valve
Inventor: LEUTNER VOLKMAR DIPL ING
IPC: G05D7/01
Filed: 1983-05-04
Abstract: A hydraulic flow-control valve (10) in a directly controlled type of construction adjustable from outside is proposed. As a housing, the hydraulic flow-control valve (10) uses the five-chamber standard housing (13) of a directional control valve for directional control with a spool. A restrictor piston (46) with a first control edge (52) as well as a pressure-balance piston (54) with at least one second control edge (59) are fitted in the continuous spool bore (18) of the housing (13) from opposite end faces (16, 17). The restrictor piston (46) and the pressure-balance piston (54) interact with fixed control edges (18) on the four housing webs (34 to 37) between the five working chambers (19, 21 to 24). Via a pressure passage (62) in the pressure-balance piston or via a transverse bore (44) in the housing (13), control pressure is admitted to the spring chamber (26), closed to the outside by a cap (15), on the side of the pressure-balance piston (54). Flow-control valves of simple and compact construction in 2-way and 3-way style with loadable and non-loadable residual flow can be realised in a uniform standard housing. <IMAGE>
