Abstract: The device is suited for refilling a container (2) with a more or less viscous material. The device exhibits a supporting structure (3), to which a supply container (6) is fastened and a temporary storage device (8) extending away from the supply container (6). A nozzle (12) is arranged on the end of the temporary storage device turned away from the supply container (6). The device further exhibits an outlet valve (23) on the end of the nozzle (12) turned away from the supply container (6) and encompasses a closing valve (22) arranged in the temporary storage device (8). The valves mentioned (22, 23) are opened and/or closed by a mechanical coupling by the pressing of a container to be filled (2) on a first plunger (15).

Abstract: A box is folded from a flat blank of sheet material. The flat blank of sheet material has a bottom portion, two side walls correspondingly connected via folds to first opposing edges of the bottom portion, and two end walls correspondingly connected via folds to second opposing edges of the bottom portion. The second edges extend perpendicular to the first edges. The end walls are of "double-wall" design, including inner and outer wall portions. Connecting portions are provided, with each connecting portion connected to intersecting edges of a side wall and a corresponding inner wall portion of an end wall and symmetrically foldable about a fold diagonally extending from a corner of the bottom portion such that in an erected state of the box the connecting portions are foldedly received between the corresponding inner and outer wall portions of each end wall.

Abstract: An apparatus for filtering and separating flowing medium by reverse osmosis, ultrafiltration, and microfiltration. Disposed in a closed housing is an element stack comprised of disk-shaped spacers and filter elements, with a respective filter element being disposed between each two spacers, about which the flowing medium flows. The housing has a spherical configuration.

Abstract: The heating system for an operating table comprises a multi-layer heating pad (2) having at least one heating segment (12a, 12b, 12c, 12d) which is adapted for being electrically heated and which is pervious to X-rays. A control and regulating unit (3) serving to control or regulate the heating current necessary for achieving an adjustable temperature of the heating pad (2) is connected to the heating pad (2). The heating pad (2) is equiped with a heating conductor (16) comprising a resistor (18) having a specific electric resistance and being wound in helical form about a carrier (17) made from an electrically non-conductive material which, regarding its mechanical properties, is rubber-elastic in the temperature range of between T=10.degree. celsius to T=200.degree. celsius. The different layers of the heating pad (2) are intimately bonded to form a composite material.

Abstract: A construction set for the erection of support structures comprises supporting rods and at least one connecting joint containing a plurality of mutually parallel chambers. Cylindrical beads are formed on the ends of supporting rods. Those beads are inserted into the cylindrical chambers of the connecting joint. The chambers are dimensioned to form a clearance relative to the beads in order to facilitate the insertion of the beads into the chambers. The beads are formed by a rolling-in of the free ends of the supporting rods.

Abstract: The invention concerns a joining element made of metal, to connect the end face of a first beam to a second beam running crosswise to this first beam, or to another structural component, wherein the first beam's end section, which is to be connected to the second beam, is provided with an essentially centered vertical slot running in the longitudinal direction of the first beam from its end face that is to be connected, and with several drill holes in each of which a rod-shaped fastening means extending essentially across the width of the first beam, such as a dowel pin or the like, is disposed or is to be disposed, with at least one connecting flange protruding from the connecting surface of the second beam in the longitudinal of the first beam and to be attached to the second beam with a holding flange, the dimensions of which connecting flange essentially match the corresponding dimensions of the slot, and which connecting flange is provided with receiving openings each of which is able to accept one rod-s

Abstract: In a hand drilling tool, in particular for drilling out spot welds, comprising a bracing support means which is releasably mounted to the body of the drilling machine and which is displaceable in the direction of the drilling axis by way of an actuating lever which terminates in a handle, it is provided that the lever (4) acts on a fitment sleeve (6) which embraces the body (2) of the drilling machine and on which the bracing support means (3) is mounted and that the fitment sleeve (6) is adapted to be axially displaceable with respect to the body (2) of the drilling machine. To eliminate moments the axis of the lever which acts on the fitment sleeve intersects the axis of the body of the drilling machine.

Abstract: A prefabricated inner roof lining for motor vehicles comprises interconnects, conductive layers or conductive networks in its surface and/or at its side facing away from the vehicle interior for supplying or distributing the electrical energy.

Abstract: A carrying case comprises an octagonal shaped body fitted with an octagonal shaped lid, a trapezoidal shaped compartment being located on an octagonal shaped surface of the octagonal shaped lid. The compartment is fitted with a trapezoidal shaped lid. The entire perimeter of the trapezoidal shaped lid is defined by four slanting surfaces each which forms an obtuse angle with the octagonal shaped surface of the octagonal shaped lid. Each of the slanting surfaces has an outer edge parallel to an edge of the octagonal shaped surface of the lid. The body includes a wall perpendicular to the octagonal shaped surface and on which is mounted a carrying handle for the carrying case. The carrying handle is substantially L-shaped and has a shorter leg oriented perpendicualar to and fixed to the aforementioned wall and a longer leg spaced from and oriented parallel to the aforementioned wall and has its major dimension in a plane parallel to the plane of the octagonal shaped surface.

Abstract: A spacer for guiding flowing medium, especially in apparatus for filtering and separating flowing medium via reverse osmosis and ultrafiltration. The spacer has a central hole that essentially serves for the clamping together of a plurality of disk-like spacers. A filter element is disposed between each two spacers, with flowing medium flowing about both sides of the filter element. To reduce pressure loss in the flowing medium, a plurality of spaced-apart openings through which flowing medium passes are disposed about the central hole of the spacer.
