Title: Gripper shuttle for large diameter yarn and wire - ensuring stability by pulling centrally to the horizontal plane
Inventor: SCHREUS THEO
IPC: D03D47/34
Filed: 1975-05-14
Abstract: A gripper shuttle, esp. for large diameter yarn and wire, is fitted at both ends on its upper surface with a clamp lever for gripping and drawing the weft, operated by a weft feeding, releasing and cutting mechanism above the shuttle race. These weft mechanisms are assembled on a bracket which can be attached whereever required to suit the weaving width, at the edge of the shed, the weft cutting device consisting of an electrically heated wire. A thread holding device, coming into action when the weft is released by the shuttle clamp as the shuttle leaves the shed, may comprise two jaws on a vertically displaceable carriage, and the thread holding as well as the thread presenting devices are actuated by the motion of the sley working with a plunger. The shuttle clamp lever which is in action, is always the one at the opposite end of the shuttle to the picker and the impulse activating the weft end holder, which, as an alternative to the tong jaws may be a suction pipe is put out by a magnet on the shuttle. The arrangement provides optimal conditions for handling the weft economically, and the possibility of altering the weaving width without complicated work on the sley and the temples. The whole arrangement works reliably with bulky weft, and the cutter is umcomplicated and not mechanical.

Title: Swimming aid fixed to the swimmers feet - has fin on base plate which swings sideways by alternate kicking of feet
Inventor: WIPPLER HERBERT
IPC: A63B31/11
Filed: 1975-06-25
Abstract: The swimming aid consists of a forked base plate (10) on which a fin (20) is pivoted. Pivoted foot plates (12) are fitted on each fork of the base plate. The fin pivots at right angles to the base plate on a slide (22). This slide (22) is held on a torsion spring (24) in the base plate (10). The swimmer fits his feet onto the foot plates (12). By kicking the right foot and drawing up the left, the base plate swings to the left. This forces the fin to swing to the right against the cam end (31) of the base plate (10). The cam forces the fin to draw out the slide (22) against the spring (24) which tends to recentralise the fin (20) producing a forward motion which is continued by kicking each foot in turn. This method produces a swimming aid which can be used without imnatural movements by the swimmer.

Title: Powder drier for solvent recovery or vacuum drying - moves material along vertically disposed set of trays by swinging frame
Inventor: KARAU GERNOT
IPC: F26B17/00
Filed: 1975-10-29
Abstract: Powder-plus-solvent enters the drier at the top. A rotating pipe with a spiral side opening spreads it evenly along the topmost drying tray. The drying trays are mounted on a frame, which is swung from side to side by a motor-operated eccentric. The movement shifts the powder along each tray until it falls on to the tray beneath, and from the lowest tray into a collecting funnel. The funnel is made in sections spaced slightly apart, and while the powder moves down to the exit channel, the solvent fumes pass between the sections to reach the solvent-recovery condensers. For economy of energy, the motor serves not one, but a pair of tray frames, swinging in antiphase.

Title: Actuating mechanism for commercial motor vehicle sliding roof - includes electric motor with two speeds ensuring optimum closing condition
Inventor: JERONCIC STANISLAV DIPL ING
IPC: E05F15/632
Filed: 1975-11-13
Abstract: The actuating mechanism for a combined sliding and lifting roof of motor vehicle has electromechanical actuators. Electric motor used for driving has switch for forward and reverse rotation. When the roof is closed then a switch disconnects power supply to motor. The electric motor has a second, higher speed which becomes effective when the combined sliding and lifting roof travels in horizontal direction either on opening or closing. This arrangement ensures that the roof does not overshoot end positions and it is closed in optimum closing position. The second higher speed is switched on by a switch actuated by the movements of the roof. The second higher speed is disconnected and changed over to slower speed shortly before the roof reaches the closed position or when it is moved from closed position into opening position.
Patent DE-2557373-A1 (DE)
Title: Control valve for servo assisted steering - with non return valves to reinforce self centering action and prevent sticking of piston
Inventor: SANDAU HARTMUT ING GRAD
IPC: B62D5/08
Filed: 1975-12-19
Abstract: The steering servo is supplied with fluid via a control valve. This has a control piston in a floating position between two axial springs. Flow control grooves around the piston are selectively linked to a hand control pump operated from the steering wheel and to a servo hydraulic pump. The piston is self centering using a central groove. In order to ensure a self centering action if the piston sticks, the supply lines from the servo pump are fitted with non return valves. These prevent a backflow to the reservoir with the piston in a displaced position. Pressure is thus built up on one end of the piston until it resumes a central setting. In the event of servo failure the manual control can operate the steering.

Title: Diagnostic X:ray appts. heating voltage control - uses transformer with slider driven by motor connected in tracking loop
Inventor: GANS-GREHL GUENTER
IPC: H05G1/34
Filed: 1975-12-23
Abstract: The diagnostic X-ray appts. has its heating voltage stabilised by an electromagnetic circuit. The inductance of this circuit is adjusted by a transformer with a slider to set the required heating voltage. The slider is driven by a motor via a tracking control that derives its actual value input from a potentiometer mechanically coupled to the slider of the transformer. Alternatively, the actual value for the tracking loop may be derived from a DC voltage proportional to the effective heating voltage. The advantage lies in reducing the number of components needed when several X-ray tubes are being operated and/or remote control is used.

Title: Forming a socket at the end of a softened thermoplastic pipe - by dilating it over a profiled arbor while adding fresh material
Inventor: ULLMANN KARL
IPC: B29C57/02
Filed: 1976-09-21
Abstract: The end of the pipe is passed over an arbor bearing the inner profile of the required socket; a mould of the required outer profile is then placed round, and filled with plastic under pressure. This pressure forces the existing softened plastic pipe into the shape o the profiled arbor, while the new material adds the necessary extra wall thickness. This method avoids thickening the end of the pipe before shaping it, as was previously necessary to maintain sufficient wall thickness in the dilated pipe.
