Title: Improvements in Apparatus for Measuring and Indicating an Electricity Supply.
Inventor: LESTER LLEWELLYN ROLLS
IPC: G01R7/12
Filed: 1918-05-24
Abstract: 131,405. Lester, L. R. May 24, 1918. Induction motor meters; power meters. - The pressure system of an alternating-current meter of the induction type measuring volt-amperes or volt-ampere-houre consists of two coils b, c mounted at right-angles to one another on a spindle which is free to turn without control. In a single-phase circuit, the coils b, c are connected in series with a non-inductive resistance R and an inductance I respectively, across the supply mains S<1>, and by reaction with the flux produced by the series coils A, take up a position dependent on the power-factor. The torque tending to rotate the disk D is proportional to the volt-amperes at all power-factors. An additional series magnet (not shown) is mounted above the disk and partially surrounds the coils b, c to increase the forces acting on these coils. For polyphase circuits, two or three of these driving-elements may act on one or more rotating disks or drums on a common spindle In a two-phase four-wire system, two series windings, one in each phase, interact with two pressure elements, each having two movable coils mounted at right-angles and connected respectively, in series with non-inductive resistances, between the two phases. In a balanced three-phase three-wire system, one series coil reacts with a pressure element consisting of three movable coils mounted at 120 degrees to each other, one end of each coil being connected to its respective main and the other ends of the coils being connected together. In a three-phase four-wire unbalanced system, three disks mounted on one spindle are respectively driven by three driving-elements, each consisting of a series coil in one phase and two movable coils at right-angles, one connected between this phase and the neutral, and the other connected between the other two phases

Title: Improvements in and relating to automatic roller lifting devices for fabric calenders
IPC: D06C15/02
Filed: 1956-03-21
Abstract: 799,416. Fabric calenders. KLEINEWEFERS, P., [trading as KLEINEWEFERS SOHNE, J.]. March 21, 1956 [March 25, 1955], No. 8793/56. Class 42 (1). [Also in Groups XXXVII and XL (c)] In a fabric calender in which a fabric seam 4 is detected by a mechanical-electrical or opticalelectrical feeler and the resulting pulse is employed to release the pressure setting between two pressure rollers 2, 3, two feelers 5, 6 are arranged one in advance of the other but laterally offset and their pulses are tested in a switching device so that the latter responds only if the pulses are transmitted within an interval of time corresponding to the speed of the fabric. By this means the roller pressure is not released by response of one feeler to machine vibration or to a knot or dirty spot in the fabric. The pulses from the feelers are fed to a switching device for a roller-lifting relay, in which the interval of time between the pulses may be tested by the release of delayed relays or by mechanical indexing units, the switching device having been set, for the speed of the fabric. Alternatively, an electronic control may be used; the first feeler operates to fire a thyratron to charge a condenser which then discharges through a variable resistance set according to the speed of the fabric; the condenser potential controls a second thyratron, preventing it from firing on operation of the second feeler if the potential has fallen below a certain value; if the second thyratron fires, it actuates a rollerlifting relay and also fires a tliird thyratron which later switches off the relay and restores roller pressure.

Title: Improvements in, or relating to, automatic road traffic control signals
IPC: G08G1/085
Filed: 1932-03-29
Abstract: 397,584. Road signals for controlling traffic. WALKER, R. W., 26, Munro Road, Glasgow. March 29, 1932, No. 8918. [Class 118 (ii).] The interval ratio of automatic traffic control signals is automatically varied at fixed times to suit the known average traffic densities in the cross roads for the ensuing periods. A cam 3 having its radii R1, R2, R3 proportioned to represent the known variations in traffic ratio or traffic intensity is rotated at a speed in agreement with its graduation so as to determine, by means of a follower 6, lever 10, rack 8, and toothed wheel 1, the angular position of the shaft 2 controlling the interval ratio. An alternative construction is suggested by the lever 12 pivoted at 13 and having the connections shown by broken lines. Fig. II shows the cam 3 lifting a follower 6 so as to connect one of the contacts 14a .. 14k and energize the corresponding electromagnet 15a .. 15k, thus moving an arm 16 fitted on the control shaft 2 and carrying a magnet. Other forms of cam may be used, with lateral movement. Different cams, corresponding, for example, to the requirements of weekdays, Saturdays and Sundays, may be brought into. operation by a sliding movement relative to the follower 6. An extra cam surface may be provided at the end of the calculated period to suit normal requirements. Helical cams may be used, or a series of cams over which the follower 6 is made to travel in succession by being pressed through gaps in dividing plates. Cam devices operating over a considerable period, such as a week are described. Where the cam units and the controls are driven off the same motor, a conical variable friction drive may be so arranged that the act of altering the cycle also alters, in compensation, the speed of the cam units.
