Abstract: A coupling for vacuum-insulated pipe or hose lines provided for conducting one or more cryogenic media, in which a single- or multi-core coupler plug and corresponding coupler socket each have a ball valve provided with a through hole and a locking sleeve coupled to rotate its respective ball valve when the sleeve is axially displaced. When the coupler plug and coupler socket are brought together, the locking sleeves engage and are displaced axially, such that the ball valves are moved into open positions in which a conduit of the coupler plug may be extended through the coupler plug ball valve into the coupler socket. Such a coupler allows a docking procedure to be reliably performed in all radial angular positions between the plug side and socket side, without need for skilled operators, position sensor technology or a precision refueling robot.

The working bodies have either the shape of angular resin-free wooden pins of a size of 4.times.4.times.30 mm and an average Shore A hardness of about 95.degree. to 100.degree. or a flat base opposite which there is a head surface corresponding to the shape of a spherical segment.

Abstract: An apparatus for slide grinding has a slide-grinding container which is movable upwardly from a slide-grinding position thereof around a horizontal tilt axis into an emptying position thereof above a screen which is adapted to be placed in vibration and is arranged in an upper region of a collection container which is tiltable into an emptying position above the slide-grinding container. A collection chamber of the collection container below the screen has a first chute which terminates above the slide-grinding container in the emptying position of the collection chamber. The chute defines an emptying opening for returning abrasive bodies which have fallen through the screen into the slide-grinding container. The slide-grinding container and the collection container are individually tiltable and the screen is developed as a screen chute which vibrates relative to the collection container.

Abstract: A multiple coupling with plate-shaped coupling halves in which the fluid-conducting spigot and hub parts of the individual couplings are fastened. The coupling halves are held pin-centered with respect to each other and detachably to each other in coupling position by a locking-ball interlock such that a plug projection of one coupling half enters into a socket opening of the other coupling half. The plug projection is held in the socket opening by locking balls which can be released by displacement of an interlock sleeve into the open position. The plug projection which is arranged approximately concentrically to the one coupling half is provided at its end with a grip of smaller cross section for a pull member developed preferably in the form of a rope, which passes through the socket opening.
