Title: Hydrostatic guide for a work slide of a machine tool
Inventor: KIENAST HARRY
IPC: B23Q1/38
Filed: 1985-12-03
Abstract: The invention relates to a hydrostatic guide for a work slide of a machine tool, preferably a gear-grinding machine. The object of the invention is to design a hydrostatic guide for a work slide in such a way that a constant and parallel bearing gap between work slide and table bed is ensured in accordance with the loads on the work slide with little complexity in terms of control. According to the invention, the object is achieved in that an even number of supporting pockets (7) with a control unit (9) are allocated to the work-mounting surface (3) of a work slide (1), and in that auxiliary supporting pockets (8) with a constant pressure-flow generator (16) are allocated to the technological auxiliary device (5). <IMAGE>

Title: Electrical control switch
Inventor: WASSERFUHR FRIEDEL DIPL ING
IPC: H01H9/26
Filed: 1985-12-13
Abstract: An electrical control switch having two operating rockers, which are located side-by-side, are supported such that they can pivot about a common axis, and interact via two switching cams with two switching rockers which can pivot in the pivoting direction of the operating rockers, the switching cams being coupled to a blocking slide, which is arranged transversely thereto, in such a manner that the blocking slide is pushed by the operation of the one operating rocker into the movement path of the switching cam of the other operating rocker, and blocks it, and the blocking of the second operating rocker is cancelled only by reverse operation of the first operating rocker. In order to prevent the blocking slide (28) sticking as a result of seizing, for example as a result of contamination, the blocking slide (28) is loaded by a spring (34) on one side in the movement direction and, in the direction in which the spring (34) acts, has a sliding surface (31) which rests in a force-fitting manner against a switching cam (22) as a result of the force of the spring (34). The pivoting movement of the relevant switching cam (22) can in consequence be transmitted (transmission ratio 1:1 or more) in a favourable manner to the blocking slide (28), so that the blocking slide (28) engages far enough into the movement path of the other switching cam (22) even when the deflection angle (movement path) of the switching cam (22) is relatively small. <IMAGE>
Patent DE-3545019-A1 (DE)
Title: High-pressure pump with flushing device
Inventor: RAU ADOLF
IPC: F04B1/04
Filed: 1985-12-19
Abstract: There is provided for a hydrostatic high-pressure pump an automatic flushing device having a flushing valve which is arranged between the discharge duct and the interior of the pumps. The valve is open when the pressure in the discharge duct of the pump is low and it then allows the residual-oil amount, which is delivered by the pump to ensure adequate flushing, to pass and to flow back into the reservoir via the leakage oil outlet. As soon as the pressure in the discharge duct is high enough, the valve closes and the flushing process is terminated. Flushing of the pump then takes place, as previously known, by the leakage-oil quantity within the pump and the known measures within the hydraulic circuit. The flushing valve can be designed as an independent component which, in the form of a cartridge, can be screwed in in the interior of the pump.

Patent DE-3714025-A1 (DE)
Inventor: FISCHER ARTUR PROF DR
IPC: F16B13/06
Filed: 1987-04-27
Abstract: Fasteners, which are used for fastening high loads, are braced in the hole (1) by means of a spreading body (8) which is moved in a spreading sleeve (9). If the fastener is subject to high instantaneous stresses, for example as the result of earthquakes, there is the risk that the fastener may break out of the hole (1). In order to ensure that the fastener continues to maintain its retaining function, even after the occurrence of high excess stresses, the spreading sleeve (9) is operated by means of a force store, which is preferably designed as a screw spring (10). The tensile force exerted by the fastened object on the fastener is transmitted via this force store to the spreading body (8). In the event of shock stresses, the force store acts as an elastic spring element which absorbs hard shocks elastically. The fastener is thus particularly suitable for use in earthquake-hazard regions or in areas where enhanced safety requirements apply. <IMAGE>
