Title: Yarn winding machine for cross-wound reels - has traverse motion by rotor arms and variable speed gearing
Inventor: SCHIPPERS HEINZ DIPL ING DR IN
IPC: B65H54/28
Filed: 1993-05-12
Abstract: A yarn winding machine is suitable for crosswound reels. The reel is wound on a tube held on a spindle by a traverse motion and a guide. The traverse is driven by two rotors in opposing directions. The yarn is carried across the face of the guide by an upper rotor arm one way, and a lower rotor arm the other way. The constantly variable speed of drive to each rotor is by means of synchronised eccentric gear wheels. The driving spindle (1) pref. has a steady speed motor to revolve the tube (5), on which the reel (6) is formed. The yarn (4) in direction (10) surrounds the roller face (11) to press on to the wound package. ADVANTAGE - The reel is a more stable prod. despite the very high speed of winding. The energy requirement for the traverse motion is distributed evenly.

Title: Reciprocating shears for the transverse cutting of profiled plates or plate profiles
Inventor: WEISSER KARL
IPC: B23D31/00
Filed: 1993-05-21
Abstract: The invention relates to reciprocating shears for the transverse cutting of profiled plates or plate profiles, the profiled plates or plate profiles having in cross-section at least one wall section - called "steep wall section" below - which is inclined by a maximum of 20 DEG  to the reciprocating direction of the reciprocating shears. The reciprocating tool is divided into a top and bottom tool. To perform good shearing actions on the above profiled plate or plate profile, the top tool has recesses in the area of the steep wall sections. Top transverse-cutting blades are pivotably arranged in the recesses. The pivot centre of the top transverse-cutting blades lies on the shearing edge of a top blade and on the cutting edge of the top transverse-cutting blade.

Abstract: A vehicle security system comprises a plurality of sensing units 12, 14, 16 for sensing intrusion or attempted intrusion into the vehicle, and a common control module 10 connected to the sensing units for causing an alarm to be emitted in response to a signal from any sensing unit. To simplify the wiring, each sensing unit is connected to the control module 10 by a single wire. The control module 10 is arranged to vary the voltage on the wire in order to set the operating state of the sensing unit 12, 14, 16 and the sensing unit is arranged to vary the current drawn from the wire to communicate data to the control module. In the embodiment shown, the voltage on each wire is simply switched on to arm each sensing unit, and when a sensing unit detects intrusion it draws a larger current than it would normally. In a second embodiment, Fig. 2, a coded voltage is used to arm respective sensing units and when a sensing unit detects intrusion it modulates the current drawn with a predetermined code recognisable by the control module. <IMAGE>
