Title: Equipment zig zag stacking plastic foil in container - has stacking rollers mounted on driven sliding frame
Inventor: SCHNELL WILLI
IPC: B65H45/101
Filed: 1974-07-12
Abstract: Equipment includes a pair of stationary rollers and a pair of stacking rollers mounted on a driven sliding frame positioned above the the container.

Inventor: PRAK JAN WILLEM LUNING
IPC: G05F3/20
Filed: 1974-10-02
Abstract: A field effect transistor controlled current supply circuit which uses, for stabilisation purposes, so as to be independent of the threshold voltage of the field effect transistor, a further transistor control circuit. The further field effect transistor (16) has preferably a threshold voltage corresponding to that of the initial field effect transistor (13) and is connected between supply terminals (11 and 12) through a resistance (17) connected to its control electrode.

Title: Regeneration cycle control of MOS operation memories - using two delayed operation inhibition circuits for system registers etc
Inventor: BENYO ZOLTANNE
IPC: G11C11/406
Filed: 1975-04-22
Abstract: A control circuit provides for an optimised regeneration process for the MOS operation memories in digital computers. During the regeneration period the system operation is inhibited. When the regeneration period occurs the clock pulse counter (8) activates the inhibition circuit (11) controlling the ROM word register (3). After a delay the second inhibition unit (12) operates to block the ROM address register (2), the memory word register (5), the operation control unit (61) and the auxiliary unit. After the basic time period has elapsed the inhibition unit (11) operates to allow the ROM WORD register to perform normally. A short delay occurs before the second inhibition unit (12) operates to permit all other system units to continue.

Title: Yarn supply creel for textile machines - has number of spools knotted end to end on endless chain
Inventor: CARLSSON ERIC
IPC: B65H49/12
Filed: 1975-09-15
Abstract: A support for yarn packages, esp. for the supply of an automatic loom, knitting machine, etc., carries at least two spools, the ends of which are knotted together; and has a fixed guide eyelet aligned to the spool being unwound. The support includes a conveyor driven by a motor on which a number of spool holders are arranged, and move together, so that the spool being unwound, is aligned correctly to the guide eyelet. A thread detector is provided, by means of which, the changeover of the thread from the just emptied spool to the next spool is sensed, and a signal to the motor is put out. The motor then moves the conveyor to bring the next spool into alignment with the fixed guide eyelet. Relieves the operator from constantly replacing an empty with a full spool, since a full day's supply can be loaded at one time.
