Abstract: 1459439 Automatic control of elevators HITACHI Ltd 14 Dec 1973 [18 Dec 1972] 58033/73 Heading G3N In a lift control system, in which a car serves the lowest floor 1F, and a group of contiguous floors removed from the lowest floor (e.g. 40F-50F), the car travels at a higher speed from the lowest floor than is used for service of floors within the group, the higher speed being selected if advancer 7 moves by an amount corresponding to the extension of the group, without encountering a floor requiring service. The synchronizer 5 of the floor selector, Fig. 2, driven at a reduced scale proportional to car motion supports detectors 540, 510, 450, 420, 390 co-operating in sequence with one of oscillators 40-50, corresponding to the floors of the groups and enabled if a stop at the corresponding floor is required to provide deceleration control in steps from the higher speed to the in-group service speed. In-group service In response to a call from a given floor, advancer 7 moves ahead of the synchonizer to a position corresponding to the destination floor, co-operation between proximity members (39, 43), Figs. 4, 7 (not shown), controlling stepwise increments in a speed signal, by energizing in cascade relays (21F-29F) Fig. 10 (not shown), deceleration being controlled by the interaction of members (38, 36) Fig. 4, 5 (not shown) mounted on the synchronizer, resp. advancer, as the synchronizer catches up. Service from the lowest floor The advancer travels out to its limit position at 7' and acceleration to the higher speed, (relays (30F-33F Fig. 10)) being enabled, takes place. The higher speed steps during deceleration are controlled by the co-operation in sequence of synchronizer mounted detectors (41GUn-41GU1) Fig. 6 (not shown) with an enabled oscillator, e.g. (41XU40) corresponding to the destination floor whence deceleration is controlled as for in-group service. Detectors (41GDn-41GD1) co-operating with oscillator (41XD1) are used for deceleration to the lowest floor. Once the car, in its approach to the group passes a point (C 1 ), Fig. 16 (not shown) the car will not respond to any call for a floor closer to it than the lowest call already accepted.

Title: Electronically controlled needle selection system for knitting machines
Inventor: BLISS-HILL HERBERT BRIAN
IPC: D04B15/66
Filed: 1969-12-17
Abstract: 1,271,850. Knitting-machines. S T I B B E MACHINERY Ltd. 7 Dec., 1970 [17 Dec., 1969], No. 62077/69. Heading D1C. [Also in Divisions G3 and H1] A circular or flat machine includes a needle selection arrangement in which each needle has associated with it a wound permanent magnet PM, the winding of which is energised when the signal received by a pattern detector 171 reaches a pre-determined level. A sprung armature 133 normally retained by the magnet is thereupon released, and via mechanical linkwork 136, 130 determines the position of a pivoted needle jack 127.  The pattern mechanism comprises one or several punched tapes, each track of which is illuminated by a fibre optic light guide. The tapes are read by a similar arrangement of fibre optic guides 183 whose far ends are arranged at the knitting stations. In the arrangement described two tapes are read, and each station has two guides to permit staggering. The ends of the guides are held in a stationary bracket 184, and scanned by photoelectric cells 171 rotating with the cylinder and each associated with one needle. Illumination of the cells; if the tape is punched, energises the winding 191 of the associated permanent magnet PM. Due to movement of the pattern tape and cells past the respective ends of the light guide, the light intensity viewed by the cell rises and falls. When it reaches a predetermined threshold, the energising circuit for the winding is triggered, and is cut off again at a second threshold on the fall. The appropriate circuits for several windings are carried by a card 169. The field of the magnet is so disturbed by the energised winding (see Division H1) that it can no longer retain its armature 133. Each needle of the machine is associated with a jack 127 rocked into or out of its trick by an inter-engaging slide 130. The end 130b of the slide co-operates with a spring 136 influenced by the armature 133. Selection is achieved as follows: the upper ends of the springs 136 are pushed inwards by cam 140 so that armatures can be carried down onto the magnets. Selected ones are then released. Slides 30 are rocked so that their ends 130b are clear of the top of the springs, and then pulled outwards so that the jack butts 127b enter the lifting track 7. When the upper ends of the springs ride off cam 140 only certain, non-selected, ones can spring outwards above the retained armatures 133. Selected springs are impeded by the released armatures. The nds 130b of the slides are lowered. When at the next station the springs are pushed inwards the upper ends 136b of non-selected springs, which lie radially outwards of the ends 130b, push against the ends, thereby pivoting the jack butts out of track 7. Power for the necessary circuitry is derived from a rotary transformer, mounted on the frame below the take-down, the rotor of which is driven in synchronism with the cylinder. The power is supplied to power packs and converted to low-voltage A.C.
