Patent DE-3634292-A1 (DE)
Title: Brake booster
Inventor: SCHONLAU JUERGEN
IPC: B60T13/16
Filed: 1986-10-08
Abstract: A brake booster (1) with a sudden step up is presented, in which the booster is designed as a circulatory booster. This means that in the unpressurised state the pump (35) pumps through a circuit at zero pressure, which is formed, inter alia, by the control chamber (27) and the axial bore (29). When the brake is actuated, the opening (38) of the axial bore (29) is inserted into the seal (37) on the inner piston (18), so that the flow of pressure medium is throttled and a controlled pressure builds up in the control chamber (27). This pressure acts on the inner piston (18) and the sleeve (16), so that consequently the brake pressure can also build up in the pressure chambers (10, 11). Should the pump (35) fail, the control piston (26) transmits the pedal forces directly to the inner piston (27), so that only the annular area A 1 of the inner piston acts in the pressure medium chamber (10). <IMAGE>

Title: Method for disposing of radioactively loaded ion-exchange resins
Inventor: RUHBAUM MANFRED DIPL PHYS DR
IPC: G21F9/34
Filed: 1987-06-09
Abstract: The invention concerns a method for disposing of radioactively loaded ion-exchange resins. The ion-exchange resins are to be heated, compressed, and then cooled under pressure. The remaining compressed ion-exchange resins, reduced in volume, are then to be sent to an ultimate storage facility. The method according to the invention minimises the amount of radioactive wastes arising, as called for by the German Atomic Energy Act. Ion-exchange resins that cannot be compressed to a stable, rigid body alone are first treated with a thermoplastic substance or mixed with other resins that contain cellulose-like fibre.

Title: Assembled junction with releasable bar connection for three-dimensional frameworks
Inventor: KRETZSCHMAR JUERGEN DIPL ING
IPC: E04B1/19
Filed: 1988-03-26
Abstract: The assembled junction with releasable bar connection serves for the positively locking and frictionally locking connection of bars in three-dimensional frameworks which are used for the spatial connection of bodies and surfaces, for covering over rooms and open spaces and for easily and rapidly shiftable, stationary and displaceable scaffoldings with a good capacity for adaptation to the form of the object which is to be provided with scaffolding. The junction is manufactured, by welding, from pairs of planar parts with mutually opposite cutouts. The bar head has an axially displaceable screw-bolt which engages into the internal thread of a steel piece with an eyelet, with the result that the bar acts as an eyelet bar with a longitudinally displaceable eyelet. The connection between bar and junction takes place by a bolt which is configured such that it is secured against falling out without taking any further, additional measures.

Abstract: For the lining of driven roadways in the seam, a lining is proposed in mining and tunnelling, the supporting parts of which are designed as multi-part, prefabricated panels covering the bottom or the roadway floor. These individual panels are connected to one another in an articulated manner in the peripheral direction of the roadway, the joint arranged in the area of the floor lift to be expected being designed to be locked in a predetermined position. Two wall panels and two floor panels each are preferably provided, wall and floor panels being connected to one another in an articulated manner and the floor panels being connected to one another by the joint of lockable or locked design. In addition, the floor panels are secured to the rock via bolts, and the snug fit is conveniently safeguarded by placing appropriate backfilling. The special design of the lining in the form of panels produces uniform support of the bottom cut-out and ensures optimum service life irrespective of the protection of the roadway roof. <IMAGE>

Title: Method for preventing an operating current from flowing through human bodies
Inventor: MELCHIOR FRIEDRICH DIPL PHYS
IPC: H02H5/12
Filed: 1988-10-25
Abstract: A method for preventing an operating current, e.g. the mains current, from flowing through a person, especially via the heart, with preferably simultaneous touching of in each case one phase conductor or of a phase conductor and the neutral conductor at an electrical connection point, is implemented in such a way that the connection is subjected to a measurement current whose intensity is harmless to people. The measurement current flowing through the person is detected and only when the flowing current exceeds a minimum value at particular minimum load is the full operating current of the connection switched on. In order to ascertain whether any current is flowing, a test current is used which automatically flows whenever a connection between the phase conductors or a phase conductor and the neutral conductor occurs. <IMAGE>

Abstract: Dressing devices (10) are used to restore uniformity to grinding surfaces (13) on grinding wheels (12) which have become non-uniform during use. Dressing devices which are held and guided by hand are known. With these, however, precise dressing of grinding surfaces (13) is possible only with great skill and effort. Moreover, in the case of the known hand dressing devices there is a considerable risk of injury. These disadvantages are to be avoided by the invention. The dressing device according to the invention is connected to a grinding machine (hand grinding pedestal 11) and possesses a dressing member (20) which is connected fixedly to the dressing device (10) and can be moved (transversely) over the grinding surface (13) in a manner guided by a holder (19). The dressing device (10) is particularly suitable for dressing cylindrical grinding surfaces (13) on grinding wheels (12) of hand grinding pedestals (11). <IMAGE>
