Patent DE-4301860-A1 (DE)
Title: Special piston for piston engines
Inventor: STOCK STEFAN DIPL PHYS
IPC: F01B9/02
Filed: 1993-01-25
Abstract: The combination of piston, piston pin and connecting rod hitherto used in most instances (for example in all common internal combustion engines) is expensive and heavy. The weight adversely affects the service life (due to the accelerations in high-speed piston engines) and limits the maximum possible engine speed. The special piston is intended to be lighter and cheaper to manufacture and to be useable in existing engines without major modifications. The special piston replaces the three parts - piston, piston pin and connecting rod. It is of simpler construction (cost saving) and is, of course, of lighter construction (reduced wear, higher speeds). It has only one bearing (2) connecting it to the crankshaft. The rotation from the centre axis (4) of the cylinder in the course of one crankshaft rotation is made possible by the spherical design of the horizontal part sliding in the cylinder liner (3). The special piston is primarily suited to internal combustion engines, the construction of which can otherwise remain essentially unmodified. <IMAGE>

Abstract: The tubular membrane is held taut by rigid or elastic struts (d) running from the corners at both ends of the tube (e) to a centre or central body. The tension of the membrane can be altered by changing the length and or the sprung force of the central element onto which the force of the corner struts is concentrated.The kite can be folded up or dismantled by detaching the connections of the frame or the connections between the frame and fabric (g). The corner struts are joined to the central body by two links (f) the distance between which can be varied and locked.

Title: Hitch ball carrier for vehicle trailer hitches
Inventor: THUELIG WERNER
IPC: B60D1/52
Filed: 1993-04-14
Abstract: A hitch ball carrier for vehicle trailer hitches, which can be plugged with its free end 1c into a guide sleeve 8 which is fixed to the vehicle. At the free end 1c, a pushing element can be displaced longitudinally along the centre, the said pushing element acting on a moulded element 7 with clamping faces 3a which extend obliquely with respect to the longitudinal axis of the said pushing element and the said moulded element 7 being located in a lateral recess of the free end 1c. The moulded element 7 engages here in a recess 8a, corresponding to the lateral recess lying opposite, of the guide sleeve 8 and in this process locks the free end 1c to the guide sleeve 8. The pushing element consists here of a sliding guide bolt 2 which is connected to a clamping element 3 which has the ribbon surface 3a which acts on the moulded element 7. At its other end, the guide bolt 2 runs into a toothed rack 2a which intermeshes with a pinion 4 which is mounted in the free end 1c and is driven by a hand-operated wheel. The clamping element 3 is acted on at the rear by a spring 6 which surrounds the guide bolt 2 and is supported against the free end 1c. A bolt pin 11 which can slide in a guide bore hole 1d which runs transversely with respect to the longitudinal axis of the free end 1c can be actuated externally and in the clamped position of the spring 6 can be moved into and out of an indent 2b on the guide bolt 2. <IMAGE>

Title: Arrangement for making a towing connection between a ship and a tug
Inventor: ALBERT ERNST
IPC: B63B22/00
Filed: 1993-04-27
Abstract: The present invention relates to an arrangement for making a towing connection between a ship suffering sea-damage and a tug with the use of a buoy line (10) for initially making the connection and a towing hawser (6) which is connected to the buoy line (10) and which in turn can be put into the position required for towing, if need be with the aid of a pull rope (8) connected in between. In this arrangement, at least one receiving body (11) for the buoy line (10), if need be for the pull rope (8), and for the towing hawser (6) firmly connected with its one end (7) to the ship is fitted on board the ship at the yard. The free end of the buoy line (10) is permanently fastened to a floatable buoy (12) which can be launched on guide means in a directionally stabilised manner from an on-board launching device (14) to a point well away from the ship so that the buoy line (10) is extended from the ship and can be received by the tug for subsequently taking over the towing hawser (6). The launching device can preferably be remotely controlled, for example with radio control, so that the towing connection can also be made if the crew have left the damaged ship. <IMAGE>

Title: Process for producing a composite girder, and composite girder
Inventor: MITSCHKE EKKEHART
IPC: E04C3/294
Filed: 1993-08-21
Abstract: The invention relates to a process for producing a composite girder, which contains at least one steel section which is subjected to pre-bending before being encased in concrete, and to a composite girder. The composite girders known hitherto have the disadvantage that the steel sections used require a large amount of material. The object of the invention has been to provide a process which permits the use of a cross-sectionally reduced steel section without adverse effects on the overall load-bearing capacity of the composite girder. To achieve this object, it is proposed,   a) releasably to fasten on the upper part of the steel section at least one cross-section-widening pressure-exerting element which is connected in a shear-resistant manner, to load the steel section by means of at least one prestressing force applied from the outside, and to encase the lower part of the pre-bent steel section with concrete, b) to relieve the pre-bent steel section after a minimum concrete strength has been reached, in order to achieve a first change in stressing and shape, and c) to remove the pressure-exerting element or the pressure-exerting elements from the upper part after the concrete casing has set, in order to achieve a second change in stressing and shape.   The composite girders produced in this manner are used in building construction, in particular in the construction of underground car parks, public buildings and industrial buildings and in the construction of bridges.

Title: Device for removing liquid from an air/liquid separator
Inventor: MANGIALARDI JOHN K
IPC: A01G13/02
Filed: 1993-09-08
Abstract: A cyclone separator 10 separates air from liquid, which accumulates at the bottom of the separator and is continuously removed by being drawn into a rotating chamber 38 equipped with a stationary pitot tube 60. The liquid forms an annular mass round the periphery of chamber 38 and the inner end of tube 60 faces circumferentially to draw off the liquid from the chamber. The top of chamber 38 makes a sliding seal (54) with housing 40. A filter 68 and duct 66 recycle air from chamber 38 to main air outlet 14, should any air reach the chamber. Radial vanes (56) on the chamber ceiling assist the flow of liquid from the separator into the chamber. <IMAGE>

Title: Pivotable fitting part for motor vehicles
IPC: B60N2/48
Filed: 1994-01-15
Abstract: The invention relates to a head restraint, sun visor, armrest, grab handle or similar pivotable fitting part for motor vehicles, comprising a dimensionally stable, hollow or solid plastic housing part which has a pivot bearing for at least one holding rod, by means of which rod the part can be held on motor-vehicle parts.
