Title: Pressure-limiting or pressure-control valve
Inventor: LEUPOLD LUTZ
IPC: G05D16/16
Filed: 1982-02-06
Abstract: A pressure-limiting or control valve for monitoring or adjusting a predetermined working pressure in a pressure medium which acts on a consumer is provided with a housing having an inlet connection, a consumer connection and a return run connection, in which housing a control piston, by which the consumer connection can be connected to the inlet connection or to the return run connection, is mounted displaceably, a precontrol valve with a control piston being present, which, via a pressure space, is acted upon, in the opposite direction to an if appropriate adjustable control force acting upon it in one direction, with the pressure loading the control piston on one end face, and by which the pressure space can be connected to the return run connection or the inlet connection. In order to make possible, with simple construction, a sensitive monitoring of the consumer pressure, the precontrol valve has at least one sensor which scans the position of the control piston and emits a signal depending upon the respective piston position.

Patent DE-3209807-A1 (DE)
Title: Rotary compressor
Inventor: BROX DIETER
IPC: F04C18/10
Filed: 1982-03-18
Abstract: The invention relates to a rotary compressor having a fixed stator which, owing to inserted cylindrical rolls, is internally toothed, and also having a rotor, which is internally guided by an eccentric and which rolls on the inner wall and in which the number of teeth is always one less than that of the stator. Due to the exact circular fit of the cylinders of the stator and the similarly circular tooth gaps of the rotor, the latter is held by one cylinder of the stator at a time and, due to the rotational movement of the eccentric, is set into a circular revolving motion on the inner wall of the stator, as a result of which displacement chambers are formed, whose volume changes constantly from zero to a maximum value and back, and which therefore continuously form a discharge zone and a suction zone. Rotary compressors of this type are used in fields of hydraulics and pneumatics, and can be used both as a pump or as a motor. Because of the modular design, the rotary compressor is highly suitable for a multi-stage implementation and can therefore be used to achieve extremely high pressures. As a result of the compact construction (optimum power/ weight ratio) it is used even when there is limited space available. Similar rotary compressors themselves fix their rotor through their own gearing. Owing to the pressure difference between each suction side and pressure side, the gearing is subject to considerable abrasion, which increases the leakage loss. Another important factor to be mentioned is that all compressors of this type have to be equipped with an additional control device for regulating the inlet and outlet. The abovementioned problems are solved according to the invention in that the rotor, by the rotating eccentric, is always kept exactly in its circular path and that therefore no additional strain is placed on the gearing. Because the rotor slides along the circumference of the eccentric, it is possible to achieve control of the medium by flow ducts at the periphery of the eccentric without an additional control device.
Patent DE-3211272-A1 (DE)
Title: Metal-encapsulated compressed-gas circuit breaker
Inventor: ZYBACH ALFRED
IPC: H01H33/915
Filed: 1982-03-26
Abstract: A stationary contact set (20, 25) and a moving contact set (40, 37) are arranged in a housing (11), of which contact sets each has an arc contact (20 and 40 respectively) and a rated-current contact (25 and 37 respectively) surrounding the latter coaxially. The moving arc contact (40) is surrounded by a blasting nozzle (44) which moves with said contact and is connected to a compression space (45) which can be subjected to pressure during a switching-off movement and contains an extinguishing gas. The stationary rated-current contact (25) can be blasted through and, at its end facing away from the moving contact set (40, 37), is crossed over by a metallic deflection cap (17) in order axially to deflect the flow of switching gases which are produced during a switching-off movement from the switching path and flow through the stationary rated-current contact (25), cooling said gases, and to allow them to flow out along the outside of the stationary rated-current contact (25). The outer edge of the deflection cap (17) is set back with respect to the free end region (27) of the stationary rated-current contact (25). In order to remove the outlet point of the extinguishing gases, which are still hot and are partially ionised, from the outer edge (26) of the deflection cap (17) into the internal space (16) of the housing (11), and hence to avoid the risk of a flashover between the housing (11) and the deflection cap (17) even when switching off at very high currents, the deflection cap (17) supports an insulating tube (33) which is adjacent to its outer edge (26) and whose inner wall is essentially aligned with the inner wall of the deflection cap (17) on the outlet flow side. <IMAGE>
Patent DE-3211708-A1 (DE)
Title: Actuating mechanism
Inventor: BECKER BURCKHARD DIPL ING
IPC: F16H49/00
Filed: 1982-03-30
Abstract: The actuating mechanism has an endless annular kinematic path, included in which is a driving member on which a driving force engages. The driving member is motionally connected, non-positively and statically, to an actuating element which, under the action of the driving force, can be moved into any desired position along a predetermined path of motion and set there. In this arrangement, the kinematic path is defined by a channel in which a pressure medium can move. A multiplicity of rolling elements, in particular rollers or balls, is used in the channel as the pressure medium.

Title: Rotor for a wind generator
Inventor: BLUM ALBERT
IPC: F03D1/06
Filed: 1982-05-27
Abstract: A rotor for a wind generator consists of a hub and of at least two essentially radially arranged vanes (18) which are seated on this and which are pivotable about their respective longitudinal axis. To simplify the construction of the vanes and to guarantee that the vanes can be pivoted into an inactive position without much outlay at least at a high wind speed, each vane (18) is seated pivotably on a carrier bar fastened to the hub and is supported on the carrier bar resiliently about its longitudinal axis. The vane (18) can be divided longitudinally and be composed of individual segments consisting of a cicumferential shell (19), of a spirally curved formed-on leaf-spring element (20) and of a sleeve (21) which is seated at the end of the leaf-spring element and which is slipped onto the carrier bar. <IMAGE>

Title: Overhead projector
IPC: G03B21/132
Filed: 1982-09-08
Abstract: In an overhead projector, in particular for reflective transillumination of the original to be projected, consisting of a foot which accommodates the writing plate and the Fresnel lens, a stand for the lens housing and an illuminating device, the aim is to achieve the object of providing an overhead projector by means of which it is also possible to project sections of originals without bright edge strips, and which is therefore superior to conventional projectors in terms of its subjectively perceived clarity of projection. The invention achieves this object when the foot has an arrangement of diaphragms with which it is possible to cover part of the Fresnel lens. This arrangement of diaphragms enables the lecturer to project without bright edge strips, because he can cover the bright edge strips by moving the diaphragms.

Patent DE-3234059-A1 (DE)
Title: Solder connection
Inventor: TSCHIRNER PETER DIPL ING
IPC: H01R4/02
Filed: 1982-09-14
Abstract: When producing a solder connection between a lead (1,2) of an electrical element (S), in particular between a signal lead of an electrical sensor and the end (6,7) of a connecting cable (8), it is difficult to fix the conductors to be connected to one another in the correct relative position with respect to one another before the actual soldering process. Furthermore, there is a risk of forming solder links to adjacent leads. After soldering, an insulating sleeve is normally pushed over the solder point (9,10) as an insulating hollow body (5a,5b), for insulation. These difficulties are overcome by an insulating hollow body (5a,5b) having a recess (13,14) on part of its length which exposes the solder point (9,10) which has been provided, the insulating hollow body (5a,5b) enclosing the lead (1,2) and the connecting cable end (6,7) over the complete circumference at its two ends. The insertion of the lead (1,2) and the connecting cable end (6,7) into the insulating hollow body (5a,5b) takes place before the soldering process to provide an initial fixing, it subsequently being possible for the soldering to be carried out conveniently and cleanly at the point of the recess (13,14). In this way, the formation of disruptive solder links is also made more difficult. As a result of mechanically rigid construction of the insulating hollow body (5a,5b), high mechanical strength of the solder connection in the vicinity of the solder point (9,10) is achieved. <IMAGE>

Title: Flexible cable guide on system cables
Inventor: KOELLING DIETER ING GRAD
IPC: H01R13/56
Filed: 1982-11-26
Abstract: In order to increase the flexibility of a multi-core system cable (1) in the region of the cable end, the cable sheath is separated over the length of the flexible region (6) from the further cable sheath and is drawn away from the system cable except for a strip (8) which is once again separated from the separated cable sheath. The separated strip (8) ensures that the individual cores (4) occupy a position with respect to one another within the enclosed region which they are intended to occupy during manufacture, so that the individual cores can be allocated without effort to the individual cable strands or colour-sequence regions of the system cable. In the part of the cable with the sheath removed, the individual conductors are flexible in all directions so that the cable can be bent relatively tightly. In order to provide additional support for the individual cores (4), an insulating hose (9), which also covers the adjacent sheathing pieces, is placed on the part of the system cable from which the sheath has been removed. <IMAGE>

Patent DE-3326630-A1 (DE)
Title: Plastic honeycomb
Inventor: SCHMIDT MATTHIAS
IPC: A01K51/00
Filed: 1983-07-23
Abstract: To combat Varroa mites, a plastic honeycomb is proposed, in which parts of the plastic surface have, independently of the formation of the thin films in the plastic cells, a free surface on which the electrostatic charging of the plastic material can be generated or recharged. Preferably, the movement of the bees themselves is used to generate sufficient friction in order to maintain the electrostatic charge continuously and without external intervention. By virtue of this electrostatic charge, the breeding of the Varroa mite is influenced and destroyed. In the case of a preferred embodiment of the invention, the plastic honeycomb is designed in such a way that, in production, individual cells have plugs of which the height is greater than the full cell wall height, so that sufficient free surface is available for the frictional contact between bees and plastic honeycomb in order for the electrostatic charge to be maintained by the bees. This produces a method for the effective combating of the Varroa mite. <IMAGE>
