Title: Method of and device for gripping, transferring and distributing small objects one by one
Inventor: GERMAINE MICHEL
IPC: A01C7/04
Filed: 1983-09-13
Granted: 1988-03-17
Abstract: The machine picks up seeds and places them individually in a soil ball. A shallow pivotable (5) box (3) with a cover opening (11) and a suction rail (7) built into the floor stores the bulk seed, pickup being effected by the suction at rail apertures (9). Vibrations of the box ensures that all seeds are dislodged except one centred over each aperture, using an offset pin (17) on a revolving disc (16) to engage a hooked pin-jointed arm (18) and pivot the box against the action of a return spring (22). The box also pivots about a second axis (13a) formed by the vacuum feed (13) passing under a sub-floor, inverting for the opening to house over a receiver (2) with openings (26) to inclined discharge pipes (25). The final phase of releasing the seeds into the pipes is accomplished by isolating the rail from the vacuum source.

Title: Switching power supply with overcurrent protection
Inventor: BORTZEL MARTIN
IPC: H02M3/337
Filed: 1983-09-15
Granted: 1988-08-25
Abstract: The ocurcurrent protection circuit (10) is used for protecting the switching transistors (Q1,Q2), by disconnecting the driver pulses for the latter upon a critical current value (Ic) being reached.

Patent DE-3561941-D1 (DE)
Title: Lift door actuating device
Inventor: HAAS MAX
IPC: E05F15/14
Filed: 1985-10-24
Granted: 1988-04-28
Abstract: The door drive is intended for use with a relatively great number of different elevator cars, different types of sliding doors, and different widths of sliding door panels. The door drive is readily adaptable to different installations merely by appropriate adjusting and conversion work without dismounting the door drive. The door drive is fitted with its supporting structure above the door opening on the roof of the elevator car. A toothed belt serves as a drive for one panel of a sliding door and is trained around a stationary and a positionally changeable deflection roll. The positionally changeable deflection roll can be adapted to each required displacement path of a given door panel by positionally changing a shaft of such deflection roll to a preselected one of a number of fixing holes provided in the supporting structure. The maximum displacement path of the driven panel thus corresponds to the horizontal distance of the axes of the two deflection rolls increased by the radii of the two deflection rolls. Guidance of a connecting joint, arranged at the toothed belt and at a coupling bracket of the door panel, around the deflection rolls results in a gradual starting accelertion and a gradual run-out deceleration when opening or closing the sliding door.

Abstract: During the splicing operation to repair a broken yarn, in an open-end spinner, an underpressure is applied to the fibre carrier rollers after the feed opening, in the direction of fibre travel, while underpressure at the feed opening is reduced or stopped, to carry on the fibres in the first phase. In the second phase, where fibres are fed to the spinning zone, after the broken yarn end has been reversed into position, underpressure is restored to the feed opening and the application of underpressure after this opening is cancelled.
