Title: Position Control Apparatus
IPC: G05B19/21
Filed: 1968-08-22
Abstract: 1,175,469. Control of D.C. motors. INTERNATIONAL BUSINESS MACHINES CORP. 22 Aug., 1968 [5 Sept., 1967], No. 40158/68. Heading H2J. [Also in Division H3] In position control apparatus wherein error detection causes energization of drive means to reduce the error, damping is provided by energization in the opposite sense as soon as the error is eliminated, the damping energization being for a time proportional to the time taken for error correction. In the embodiment described a printed-circuit motor M drives a slotted disc (10, Fig. 1, not shown) co-operating with two photo-cells (11, 12) for position detection. In a desired position one cell is covered and the other uncovered, while an error one way leaves both cells uncovered, and a reverse error covers both cells. Signals from the cells are fed to an AND gate 14 and via inverters 15, 16 to an AND gate 18. Thus, when a " detent " signal is applied over conductor 20, a forward error would cause a signal to be supplied via an OR gate 22 to reverse-drive OR gate 26 to turn on transistors T1 and T2 whereby motor M is driven in reverse to correct the positional error, while a reverse error would cause a signal to be fed via OR gate 2 to forward drive OR gate 28 to turn on transistors T3 and T4 whereby the error is corrected by forward drive of motor M. Two similar proportional single-shot circuits 34 and 36 are cross-connected from AND gate 14 to OR gate 24, and from AND gate 18 to OR gate 22, respectively. As shown for circuit 34 a capacitor C is connected between resistors R2 and R3 in the circuits of transistors Q1 and Q2 respectively. Point A is normally held negative such that both transistors Q1 and Q2 are conducting. A forward error signal from AND gate 14 sends point A positive, cutting off Q1 and allowing C to charge via R2. Termination of the error signal allows Q1 to conduct again and the charge on C sends point D positive to cut off Q2 and provides a negative-going output from point E while C discharges via R3. This output is fed to OR gate 24 to produce damping energization of motor M for a time dependent upon the time that the error signal persisted, and upon the ratio of time constants C.R2 and C.R3. The value of R2 might, for example, be 20 K ohms and that of R3 be 5 K ohms.

Carcase ply ends are turned against the shoulder of a stationary building drum a by means of a cylindrical flexible inflatable sheet 2 positioned adjacent the drum shoulder and having a narrow band 3 of greater extensibility than the rest of the sheet whereby, on initial inflation, Fig. 2, the band 3 distends to effect initial turn over of the ply end, and on further inflation, the rest of the sheet distends, Fig. 3, to move the distended band 3 against the drum shoulder for completion of the ply turn over. As shown for turn up of the ply ends around a bead core 10 and filler 11, the sheet comprises the radially outer wall of an annular tube which is of flat band form when deflated and is carried on a cylindrical support 4 releasably latched, by rotatable latches 6, 8, to a lug 5 on the drum support b. The tube is reinforced against extension by two cross-laid plies of bias cut textile fabric which extends only partially around the tube section to leave the unreinforced band 3. For ply turn down, the sheet would be supported around the drum shoulder for radially inward distension.

Abstract: 1391217 Gas/liquid contact COMPAGNIE ELECTRO-MECANIQUE 1 Sept 1972 [3 Sept 1971] 40711/72 Heading B1F The invention is based on the fact that as illustrated in Fig. 1 gas from a high velocity gas/liquid emulsion from point 1 will pass into a low velocity liquid from point 2. Thus, in a gas/liquid contact process in which liquid introduced at 11 and 11', Fig. 3, travels generally in an outward counterclockwise spiral path to leave at 12 and 12', gas introduced at 3 forms an emulsion with liquid from 6 which is allowed to expand through expansion zone a (1, 1) to accelarate its flow into separation zone b (1, 1) where gas passes from the accelerated stream into a slower decelerated liquid from c (2, 2) to form a second emulsion which expands through expansion zone a (1, 2) to accelerate to separation zone b (1, 2) where the gas passes from the accelerated stream to slower decelerated liquid stream from 9' to form an emulsion which is accelerated and expanded through zone 1, 3 to separation zone b (1, 3) where gas separates out and leaves at 10. Gas introduced at 3' passes through the apparatus similarly. To maintain the generally outward counterclockwise spiral flow of liquid, some of the liquid from zone c (2, 2) passes to zone c (1, 1), and some of the liquid from zone c (2, 3) and 9' passes to zone c (1, 2).

The keyboard includes keys 11a, for entering the amount to be withdrawn, and keys 33, for entering a secret code individual to the machine and/or the machine operator. After such entries, the amount is dispensed in the least possible number of notes or, if an entry is also made via keys 22 in notes of a particular denomination. Lights 44 (Fig. 1), indicate empty storage spaces 15b. An indicator (not shown) of full storage spaces may also be provided.
