Abstract: 1,212,574. Knitting-machines. E. MAYER [trading as MAYER & CIE]. 18 July, 1968 [23 Sept., 1967], No. 34156/68. Heading D1C. Two selections are made at each feeding station of a circular machine by providing a double vertical bank of presser members 141, 14II which are actuated by one and the same pattern drum, the first bank of presser members when actuated deflecting the corresponding jacks inwardly so that they and their needles remain at a low level A whilst those jacks not engaged by pressers 14I are elevated by a raising cam 9 to a tuck height B. At this level the second bank of pressers 14II makes a selection and the pressers 14II actuated by the pattern drum deflect the corresponding jacks inwardly so that they and their corresponding needles remain at tuck height 'whilst the remaining jacks and their needles are elevated to a yarn clearing and knitting height. Consequently a double selection is made at each feeding station one at miss height and one at tuck height by the actuation of a double bank of pressers from a single pattern drum. For this purpose the pattern drum is advanced twice the distance between the vertical rows of the pegs in the drum so as to correspond to the distance between the banks of pressers.

Title: Improvements in angular motion reproducing systems
IPC: G05D3/12
Filed: 1954-11-25
Abstract: 761,955. Electric control systems. GENERAL ELECTRIC CO. Nov. 25, 1954 [Nov. 25, 1953], No. 34220/54. Class 40 (1). In a positional control system using selsyns at transmitter T and receiver R, wherein the polyphase stators 6-8, 9-11 are energized from a polyphase supply and the error signal controlling the servomotor 15 to drive the receiver rotor 13, is derived from a phase comparison of the single phase outputs of the transmitter and receiver rotors 12, 13, the output of the transmitter is frequency divided for transmission at a lower frequency, and frequency multiplied at the receiver. As shown, the output of the transmitter rotor 12, the phase of which corresponds to its angular setting, is converted into pulse form at 23, e.g. by clipping, and frequency divided by four at 24, the resultant pulses modulating a carrier for transmission by line or radio at 17 to the receiver 21 where, after demodulation at 25, the pulses are frequency multiplied by four at 26 and converted into sinusoidal form for phase comparison at 22 with the output of the receiver stator 13. The system is independent of phase shifts introduced by the three-phase tie line 5 or by the signal transmission line, provided these phase shifts remain substantially constant, and for precision control the rotor 12 is driven by the control motion source 3 through a multiplying gear unit 14, the servomotor 15 driving the controlled apparatus 4 through reducing gearing 16, but driving the receiver rotor 13 directly. The invention is applicable to telemetering or control of an electrical power system, e.g. the control of a valve for a turbine. The signal transmission 17 may be effected over a telephone line.

Filed: 1922-12-18
Abstract: 213,319. Chamberlain & Hookham, Ltd., and James, S. Dec. 18, 1922. Electricity, supplying by time controlled apparatus.-After insertion of a coin or token, an arm t operated by a handle u is freed and rotated in a counterclockwise direction thereby engaging a lever v to wind up a clockwork spring and through the medium of the coin &c. rotating a cam w. The cam deflects a blade spring x secured to an arm y on the pivot of a mercury switch a having terminals b through which the circuit is completed when the switch a is horizontal. Movement of the switch is prevented by a catch z engaging the lever y. During the return of the arm t a projection s thereon trips the catch z by engaging an inclined shoulder 3, so that the spring x moves the switch to close the circuit, the switch being then retained. by the engagement of a lateral projection d on an arm c with a step j in a slotted lever f controlled by the clockwork. At the end of a predetermined time a pin h on a. wheel i of the clock passes a shoulder k on the lever f moving the latter and allowing the projection d to pass out of the slot and the switch tb open the circuit. The release of the arm c takes place in two stages, first, the projection d is freed from the step j, then it is allowed to pass out of the slot. If the circuit is opened by an external switch, an electromagnet l moves an arm m into engagement with a stop o on the balance wheel n to stop the clock. Indicators.-A scale and movable index connected to the clock indicates the unexpired period for which the apparatus can remain in action. Coin action, weight and mechanical-connection; tokens of special form.-The coin or token first tilts by weight a catch r out of engagement with the projection s on the arm t and then transmits the movement of the catch r to the cam w when the catch is acted on bv the arm t.
