IPC: B65B7/06
Filed: 1979-04-12
Abstract: A process and an apparatus for the closing of cuboid bags filled with a pourable material are proposed. The process and the apparatus are intended to ensure that the finished bag packs (1) have a cuboid shape despite the shallow-forming of the closure. For this purpose, the bag walls arranged transversely relative to the closing seam are inclined relative to one another during the shallow-forming of the upper bag-edge region. In the apparatus, this takes place by means of the pivoting of two driving walls (14, 15) of the conveyor device (10) which respectively guide a bag (1) between them. <IMAGE>

Title: Shaft rotation direction determn. for vehicle direction determn. - by using magnetic sensor and asymmetric magnet producing direction dependent pulsed signal duty cycle
Inventor: ROGGE JOACHIM DIPL ING DR ING
IPC: G01P3/481
Filed: 1979-08-02
Abstract: The arrangement for measuring the direction of rotation of a shaft, esp. one corresp. to the direction of motion of a vehicle, gives a reliable indication at low cost. The transducer coupled to the shaft produces a series of signals corresp. to the direction of rotation which is determined by an evaluation circuit. The duty cycle of the signal series is dependent on the shaft rotation direction. The evaluation circuit determines the duty cycle and produces a rotation direction signal. The duty cycle is greater or less than unity according to the direction. This is achieved by use of a magnetic sensor (6) and a rotor (3) with different length switching paths (a1,a2) for different directions. The sensor detects the passage of an asymmetrically placed magnet (4) on the rotor.

Title: Winding-frame spindle with package-tube clamping pins - movable radially by longitudinal displacement of wedge=shaped elements
Inventor: BUSCH HANS-JOCHEN
IPC: B65H54/54
Filed: 1980-11-27
Abstract: The spindles of a yarn winding frame have clamping devices to grip the package tube comprising a series of radial pins projecting through apertures in the spindle casing. The inner ends of the pegs have an inclined face resting against longitudinally-movable wedge-shaped elements which effect a radial displacement of the pins. The wedge elements form part of a ring-shaped slider which is pressed beneath the pegs by springs to engage the clamp. The opposite end of the slider abuts a piston enclosing an annular chamber into which compressed air can be fed along the spindle axis, thereby compressing the springs to withdraw the wedges and allow retraction of the pins. The clamping elements are relatively small, and can be as numerous as required, even on relatively narrow spindles. They automatically adjust to variations in the inner diameter of the package tube, and a large clamping force is produced from a comparatively small longitudinal force.
