Title: Electrical capacitor with liquid cooling
Inventor: SCHMAUSS HERMANN DIPL ING
IPC: H01G4/12
Filed: 1981-12-22
Abstract: The invention relates to an electrical capacitor, especially a radio-frequency power capacitor with liquid cooling, which consists of a closely-sintered ceramic dielectric body (1) separating the metal layers of the two plates. The dielectric body (1) may be of disc-shaped, tubular or pot-shaped design, and the heat loss generated in the dielectric body (1) is dissipated by a cooling fluid, especially by water, which circulates in a cavity around one or around both plates. In order that erosion of the plate metal layers (3, 4), which consist of silver, is prevented when using any desired cooling water, a glazed layer (14), which is resistant to the cooling fluid and whose coefficient of expansion is matched to the coefficient of expansion of the dielectric body (1), covers the metal layers (3, 4) which are in contact with the cooling water. <IMAGE>

Title: Pipe manifold for heating installations
Inventor: MAILE SIEGFRIED
IPC: F16L41/02
Filed: 1982-01-19
Abstract: The invention relates to a pipe manifold for heating installations, the housing of which is according to the invention divided into two chambers (3 and 4) by a partition (1) extending diagonally. The connection pipe pieces (8 to 10) are in this pipe manifold set back as far as possible, in order that for example the valves put onto the connection pipe pieces do not project so far forwards. With the pipe manifold, the overall installation depth for pipe manifold and the devices connected, such as valves or thermostats, can be considerably reduced. Moreover, connections with larger diameters can be provided on all the external sides, as the diagonal partition (1) can be connected to the manifold housing (2) in the corners of a pipe manifold which is rectangular in cross-section. <IMAGE>

Title: Method for guiding an aircraft to be refuelled in flight
Inventor: WINTER LUDWIG DIPL PHYS
IPC: G05D1/12
Filed: 1982-01-23
Abstract: A method for determining direction only from range information items, in this case TACAN (Tactical Air Navigation) in air-to-air mode is represented. The directional information determined is used for guiding one or more aircraft as accurately as possible and without other aids such as, for example, radio telephony contact etc. to a tanker for air-to-air refuelling. Both aircraft, tanker and aircraft to be refuelled are equipped with a TACAN device which operates in air-to-air mode. Since only range information items are available in this mode, the necessary directional information is determined by the following method. In a first step, a programmed course change towards the target aircraft is carried out. After that, the distances from the tanker are measured at fixed time intervals ( DELTA t) with the aid of the TACAN. The change in distance from the tanker is used for deciding whether the aircraft to be refuelled is on an optimum approach course or whether course changes have to be carried out. <IMAGE>

Title: Flowmeter
Inventor: KUEPPERS KARL DIPL ING
IPC: G01F1/06
Filed: 1982-05-27
Abstract: The invention relates to a flowmeter with a rotor which is rotatably driven by the liquid to be measured and is held without bearings, floating relative to the stator, and whose speed is proportional to the liquid throughput. The object of the invention is to improve the measurement accuracy in comparison with known flowmeters of this kind and to reduce to a minimum deviations from linearity between flow and rotor speed. In addition, a simple design is sought. The abovementioned object is achieved according to the invention in that the rotor surrounds the stator as an external rotor, the gap between the rotor and the stator is formed in a special manner, and the liquid is introduced, with a tangential component with respect to the axis of rotation of the rotor, into the gap between the rotor and the stator. The flowmeter according to the invention is also distinguished in its production, using simple manufacturing techniques such as assembly from plastics injection moulded parts, by high measurement accuracy, very small deviations from linearity between throughput and rotor speed, and small manufacturing tolerances, so that it can be used as an accurate flowmeter without readjustment. In the drawing, in which a flowmeter according to the invention is shown in longitudinal section, 2 represents the stator, 3 the rotor, and 4 the gap between the stator (2) and the rotor (3). <IMAGE>

In an advantageous embodiment, the flexurally elastic tube is joined to the pipe by means of a cover piece, this intermediate piece being mounted on an opening in the pipe so that the novel device can still also be installed in tubes retrospectively.
Patent DE-3317811-A1 (DE)
Title: Freely vibrating screening machine
Inventor: DEUTSCHER OSWALD DIPL ING DR I
IPC: B07B1/50
Filed: 1983-05-17
Abstract: The invention relates to a freely vibrating screening machine which has a screen frame that is horizontal to inclined and has a drive which causes the screen frame to vibrate. Such vibration frequently proceeds horizontally in a to and fro displacement. It can also proceed upwardly or downwardly inclined, or else elliptically. A disadvantage of such screening machines consists in that screening material frequently stops up the screen openings, so that the screening performance is reduced and there is also damage to the screen openings. The invention eliminates this disadvantage by arranging for the screen frame to be additionally delayed in the vicinity of the upper reversal of direction of its vibrating movements through the action of an additional force on the screen frame. As a result, the particles jammed in the screen openings are largely flung out upwards, thus freeing the screen.
