Title: Transport device for sewing machines
Inventor: KUSS PETER DIPL ING
IPC: D05B29/06
Filed: 1989-03-07
Abstract: According to the invention, by means of a force sensor which is known per se, for example a piezoceramic element, the momentary presser foot force is determined during the sewing work, the measured value is compared in an evaluation circuit with 2 adjustable control variables, and, depending on the result of the comparison, an actuator, for example a pneumatic pressure transducer influenced by a direct-current motor, is activated. The presser foot force is regulated via a working cylinder by means of a change in pressure. <IMAGE>

Patent DE-3908682-A1 (DE)
Inventor: THOMA GEORG
IPC: F16M11/06
Filed: 1989-03-16
Abstract: The invention relates to a mechanism for balancing the weight of an object to be swivelled about a pitch axis, especially for balancing the weight of a film or television camera mounted on a tripod head. The pitching torque produced during swivelling of the object (2) is compensated by a restoring torque, which acts with the aid of a spring arrangement (12) on the pitch axis (A) via a lever arm (11). In order to increase the pitching range and to achieve an ideal compensation of torque for all pitch angles, it is proposed according to the invention that the balancing mechanism (1) has a reduction gear (5) with a reduction ratio of 1:2 between an input shaft and an output shaft (4 and 8, respectively), the axis of the input shaft (4) being the pitch axis (A), and the spring arrangement (12) acting on the output shaft (8) via a lever arm. <IMAGE>

IPC: E01B31/24
Filed: 1989-03-25
Abstract: The invention relates to a process for repairing railway fastenings on wooden sleepers. After removing the old sleeper screw, which becomes loose in the course of time due to rotting of the wood, a thread is cut into the passage holes (11) of the ribbed sole-plate (2). New sleeper screws (33) with a single or double thread (37, 39) having a greater volume than the thread of the old sleeper screw are screwed into the boreholes (11) of the sleeper (1). One thread (37) of this single or double thread (37, 39) has a larger outside diameter that the passage hole (9) of the ribbed sole-plate (2). This thread (37) is matched to the thread (30) cut into the ribbed sole-plate (2). To permit simple guiding of the new sleeper screw (3) into the borehole (11) of the sleeper (1), the old cut-in thread (12) is used for guiding a thread cutter when cutting the thread (30) into the ribbed sole-plate (2) and for the new sleeper screw (33). Fig. 6 is intended for the abstract. <IMAGE>
Patent DE-3910691-A1 (DE)
Inventor: SCHONLAU JUERGEN
IPC: F16J10/02
Filed: 1989-04-03
Abstract: A threaded pipe connector 2 is incorporated in a plastics body 1 during moulding. A ring-shaped intrusion 9 of the plastics material between annular extensions 4, 5 of the connector 2 provides a seal even during thermal cycling. Because of the different coefficient of expansion of the non-plastics connector 2 than the plastics material thermal expansion or contraction will produce a seal either at sealing surface 7 or sealing surface 6. A clutch store cylinder has a magnet 20 embedded in a piston 15 by injection moulding which activates a reed contact 21 in the bottom portion 22 of the cylinder part 13. A fluid assembly, in particular a plastic material clutch master cylinder is arranged for suspension from two points (26, 27). The two points form an axis of rotation (24) for the cylinder (33) and are constituted by the ends of an elastic bracket element (28) for supporting the master cylinder (33). The master cylinder is connected to a flexible hose line, enabling a rigid connection between the piston (32) of the master cylinder and its push rod (51). Recesses (29) are provided with undercuts (30), to enable snap fixing of the master cylinder to bracket (28). A substantial saving of costs of manufacture and of assembly of the master cylinder may, therefore, be achieved. <IMAGE>

Title: Twin layers packing carton with plastics inner container - has easier fixing support plate for spout extending through to outside
Inventor: SCHENK BERND DIPL ING
IPC: B65D77/06
Filed: 1989-04-29
Abstract: The double layered carton such as a winebox comprises a thermoplastics inner container and a cardboard outer container with punched hole separated in the useful position so that the closable spout of the inner container can be drawn through. At the transition between the spout (5) and inner container (2) there is a locking plate (7) through which the spout is pushed. This locking plate (7) has in relation to the axis of the spout (5) two diametric support webs (16) which are bendable per ' se and which have an end side projection (12). The punched out part (10) on the outer carton is complementary with the locking plate so that it can be drawn out with the spout. When the spout is drawn out and the support webs bent down the locking plate engages in recesses (13) provided in the cut out section corresponding to the projections (12) in the locking plate. ADVANTAGE - Easier locking of the spout in its position of use on the outer carton.

Title: Test apparatus suitable for testing the solubility of solid oral pharmaceutical forms in liquids
Inventor: BENZ REINHARD
IPC: G01N13/00
Filed: 1989-06-02
Abstract: The apparatus has a tub used as a water bath, in which at least one test vessel (1) is arranged, the liquid in the tub being used for giving the test fluid in the test vessel or in the test vessels the required inspection temperature or the required temperature behaviour. In order to make it possible to work with a gas-free and thus essentially air-free test liquid, the test vessel is provided with a connector (2) on the bottom (1a), which fits tightly in an inlet and outlet connector (5) in the bottom (3) of the tub. Each of the two connectors (2, 5) is closed by a valve, the valve disc (33) of the vessel connector valve closing the latter on the upper edge, and the valve cone (22) of the tub-bottom connector (5) closing the latter on the lower edge. The test liquid is supplied through a line (22b) passing through the valve cone (22) of the tub-bottom connector and through the space (40) between the two valve heads. This space can be washed by providing the valve cone (22) of the tub-botton connector valve with an additional line (22c) which is used for draining both the test liquid and the wash liquid. <IMAGE>

Title: Whirlpool bath with air and water jets - allows circulation of water from outlet to tube and subsequent emptying and clean flushing
Inventor: PIEPER FRITZ
IPC: A61H33/02
Filed: 1989-08-29
Abstract: The whirlpool bath has a controlled water and air bubble system with a closable water outlet and a pump and blower for the flow medium.

Title: Rapid operating mechanism for injection moulding tool - has constant speed and is operated by short stroke piston through various linkages gives faster closing movement of tool
Inventor: MAERCKER DETLEF
IPC: B29C45/68
Filed: 1989-10-17
Abstract: An arrangement (A) for fast closure of an injection moulding tool with cantilevered pillars is claimed. The two halves are mounted on bolster plates one of which is fixed, the other moving on a sliding shoe on a base frame. Fast operation of the moving half is achieved through a linkage system which is operated by a piston pivoted at a fixed point below the moving plate.  The piston rod is connected to a triangular link which by means of a crank is fixed to the base frame. The other end of the link is located on a fixed pivot on a frame at the rear of the moving plate.  Short piston movement results in a longer, but faster movement of the moving plate. ADVANTAGE - Use of (A) eliminates the transfer of reaction forces onto the fixed tool plate. (A) requires no additional length for the closure unit.
