Title: Sealing for joint for eccentric worm screw pump
Inventor: STREICHER MAX
IPC: F16D3/18
Filed: 1981-06-11
Abstract: The bevel wheel (1) is sealed and secured on the rotor of an eccentric worm screw machine by means of shield pin (10). The bevel wheel (2) is fixed to the end of the tubular interconnection piece (3) and carries fitting rings (4) which can be detached by means of pins (11) and engage, by means of an annular projection, the outer part of a disc-shaped diaphragm (8) and thus retain this at the outer rim of the bevel wheel (2). Both bevel wheels are held together by a collar stud (5) in such a way that they can be pivoted relative to one another adjustably and to a limited extent, and are encircled by a protective sleeve (6) which at its ends in each case is sealed internally by an O ring. The interior of the joint is thus sealed on all sides, the diaphragm (8) being able, in the case of pressure fluctuations, to deform inwards into the frustoconical cavity formed by the bevel wheel (2). In order to be able to compensate even for high external pressures, the joint housing is filled with lubricant. Instead of the diaphragm it is also possible to provide a different volume-balancing sealing element. In spite of small balancing movements it is thus possible to balance even high pressures such as those which occur, in particular, in submerged pumps. <IMAGE>

Title: Method and device for continuously measuring distances and position displacements
Inventor: BEUTER KARL DR
IPC: G01S15/10
Filed: 1981-10-23
Abstract: In a method for continuously measuring distances and position displacements of objects in accordance with the pulse echo principle, a reference section is established in the sound ray path for determining and compensating for changes in the speed of propagation of the sound along a measuring section. With each pulse, the transit time both on the reference section and on the measuring section is detected, several pulses being sent out in continuous sequence. The position displacement is calculated in accordance with the formula e DIVIDED f(b-ca DIVIDED d). In this formula, e is the length of the reference section, f is the starting value of the transit time on the reference section, a and d are the instantaneous values of the transit time on the measuring section and the reference section, b is the difference between a and the starting value of the transit time on the measuring section and c is the difference between d and f.

Title: Pressing-out and disintegrating device
Inventor: SYRBIUS GERHARD DR
IPC: B30B9/12
Filed: 1981-12-22
Abstract: A disintegrating device is provided by means of which a very high pressing-out force can be achieved with at the same time excellent disintegration of the material to be pressed out, and by means of which the pressed-out liquid can be drained off at that point where its major part is released, without a significant pressure drop occurring in this region by the liquid-drainage openings. This object is achieved by the arrangement of disintegrating pins having radial drainage bores which are open towards the screw axis and which are in connection with a liquid-drainage network. The sharp-edged disintegrating pins equipped with the drainage bores project into a pressing cylinder in which a rotary screw is arranged on which are mounted sharp-edged disintegrating tools. The stationary disintegrating pins interact with the rotating disintegrating tools mounted on the screw in such a way that, between the two, a disintegration of the material takes place.

Title: Saddle for two-wheeled vehicles or the like
Inventor: ROPELIUS HORST
IPC: B62J1/28
Filed: 1982-02-22
Abstract: Saddle for two-wheeled vehicles or the like, having an upholstered element which is arranged about a carrier element, has a seating surface and bounds a downwardly open cavity on the side opposite the seating surface. In the case of two-wheeled vehicles, objects which are to be carried along, such as for example a tool, puncture repair kit or the like, are accommodated in a bag attached to the frame or to the saddle. The bags which are to be attached during the assembly of a two-wheeled vehicle not only make the two-wheeled vehicle more expensive to manufacture but also have a disadvantageous effect on the appearance as a whole and incite thieves to steal the objects stored therein since usually the bag is not locked. The cavity which is present on the underside of every saddle is closed off according to the invention by means of a preform which is attached to the upholstered element or to the carrier element of the saddle. As a result, a chamber for holding tools, puncture repair kits and the like is easily formed. So that this chamber can be opened or closed without the aid of a tool, the preform is fixed to the upholstered element or to the carrier element of the saddle by means of a releasable connection, for example by means of a catch device. <IMAGE>

Title: Load control for small power stations
Inventor: GRADL RUDOLF
IPC: F03B15/16
Filed: 1982-05-14
Abstract: The load controller is especially suitable for a small power station having a hydroelectrically driven AC generator which is isolated from the public mains network. The AC generator (G) supplies a basic load impedence (ZG) and an additional load impedance (ZL), designed as an electrical heating apparatus, in which the excess energy which is instantaneously not required is consumed. A measuring element (M) generates a nominal voltage, which is proportional to the voltage on the basic load impedance (ZG), as a control variable for a controller (S) which, for its part, drives an AC power controller (W). When the basic load impedance (ZG) varies, the current through the additional load impedance (ZL) is regulated by phase-gating control in such a manner that a constant voltage is set on the basic load impedance (ZG). <IMAGE>
