Filed: 1922-11-10
Abstract: 205,776. Clouterie et TrÚfilerie des Flandres Soc. Anon. Oct. 21, 1922, [Convention date]. Drawing wire.-A spool on which wires, metal bands or pipes are wound during drawing or rolling operations is provided with a gripper-carrying drum of a diameter smaller than that of the spool and located below it. The gripper f, Fig. 1, is attached by means of a chain e to a drum c which is recessed to accommodate the gripper and is provided with a spiral groove to lead the wire on to the spool a. The drum may be separate from the spool and may be of cylindrical, polygonal or of spiral &c. cross section so as to reduce the shock at starting.

Abstract: 662,754. Automatic frequency control systems. PHILIPS ELECTRICAL, Ltd. Dec. 2, 1948 [Dec. 5, 1947], No. 31235/48. Class 38 (iv). A reflex-klystron oscillator has its frequency automatically controlled by a voltage derived from a frequency discriminator, the control voltage being converted by modulation to a proportional A.C. voltage which is then rectified and fed to the reflector electrode or cathode of the oscillator, and the rectifier circuit is fed through an inductive or capacity coupling so as to isolate the modulator and discriminator from the high D.C. voltage of the klystron. As shown, a superheterodyne receiving circuit 1 ... 7 employs the klystron 2 as the local oscillator, and I.F. is fed from the amplifier 4 to a frequency discriminator 8, the output from which is fed to the grid of a modulating amplifier 10. A.C. is also fed to the grid' from a source 14 and the amplitudemodulated output is passed by a transformer 15 or a capacity coupling to a rectifier circuit 16 including an output filter 17, 18.

Abstract: 1,058,942. Analogue to digital converters. SOLARTRON ELECTRONIC GROUP Ltd. June 4, 1965 [Aug. 4, 1964], No. 31577/64. Heading G4H. A digital voltmeter comprises an operational amplifier A (Figure not shown) with capacitive feedback (C2), a switch (S1 for applying a charge proportional to the input voltage to capacitor (C2) a switch (S2) for connecting a reference voltage to the amplifier input through resistor (R1) and for connecting resistor (R2) across capacitor (C2) a trigger (G) responding when the amplifier output voltage reaches zero for resetting a bi-stable circuit (B) to establish an interval during which clock pulses are counted. The arrangement is such that the digital measurement is logarithmic. The input voltage (Vi) is first applied by a switch (S1a) to a capacitor (C1). Then switch (S2) is closed briefly so that a balance is established whereby Vo, the output of the amplifier equals - Vref R1/R2. Then switch (S1 transfers so that the input side of capacitor (C1) is earthed and its charge shared with (C2). Vo now equal Vi C1/C2- Vref R2/R1. Switches (S2) now close again so that bi-stable (B) is set (contacts S1b and S2c closed) and currents flow into the summing function at the input of amplifier (A) and Vo falls exponentially to the value Vref R2/R1 passing through zero at the end of a time interval equal to a constant plus a term proportional to the logarithm of the input voltage Vi. Oppositely biased diodes (MR1, MR2) connected to earth via resistor (R3) in effect open-circuit the feed-back loop when the voltage level reaches a value approaching zero from either direction. By this means the zero transition is arranged to be rapid and trigger (9) operates instantaneously.

[Also in Divisions G1 and G3] The viscosity of a liquid is determined by rotating a cup 3 (Fig. 1) in the liquid at a constant speed and measuring the back torque on the stator. The driving force is supplied by an A.C. synchronous motor comprising stator windings 21, 23, ferromagnetic stator assembly 231-2-3, and rotor 26. The windings 21, 23 are mounted on a fixed housing 10. The flux produced when energized passes through gaps L 1 , L 2 , L 3  to members 231, 232, 233 which are carried by a shaft 23 attached to one end of a spiral spring 25. Located Centrally is the rotor 26 on a shaft 260 carrying at its lower end a permanent magnet 27 in a non-magnetic sheld 11 through which it magnetically couples with magnets 31 on a cup 3 which rotates with the rotor 26 about a bearing 32 at the end of a pin 12 protruding from the shield 11. The torque required to maintain the cup 3 rotating at synchronous speed is reflected in the stator assembly and produces an angular displacement of shaft 23 against spring 25 indicative of the viscosity of the liquid which is indicated by a pointer 5 attached to the shaft, or by an electrical transducer. In one embodiment (Figs. 3, 4, not shown) shaft 23 is associated with a followup switch arrangement to maintain the viscosity of the liquid at a predetermined value, by controlling the preheating or a valve of a diluent pipe.
