Title: Method of measuring the accuracy of time-pieces
IPC: H01H67/30
Filed: 1963-02-14
Abstract: 996,671. Clocks and watches. GREINER ELECTRONIC A.G. Feb.14, 1963 [Sept. 29, 1962], No. 6056/63. Heading G3T. In measuring the accuracy of timepieces, and in order to avoid the use of a tick counter which requires adjustment for different nominal ticking rates and further to avoid inaccurate readings arising from spurious noises during the measuring period, a method of making such measurements consists in this, that the number of cycles of a standard frequency signal (S.F.S.) counted between a tick initiating the measuring process and a later tick terminating the measuring process is used as a measure of the accuracy, in which beginning with the initiating zero-numbered tick a constant waiting time is used in such manner that the first tick occuring after the end of the waiting time terminates the counting of the cycles of the S.F.S., and in which, when measuring a timepiece of zero inaccuracy and having the highest nominal ticking rate of the timepiece to be measured, the constant waiting time ends between an eve-numbered tick terminating the counting of the cycles of the S.F.S. and the preceding odd-numbered tick. Timepieces of the usual nominal ticking rates of 21, 600; 19, 800; 16, 200; 14, 400; and 12, 000 per hour may be measured in any order. Each gives a nominal even number of ticks within a period of 12.0 secs. If an S.F.S. of 7, 200 per. sec. is used, exactly 86, 400 cycles will occur in 12.0 secs. The waiting period beginning with the initiating tick corresponds to the highest nominal rate i.e. 21, 600 and is conveniently 11<SP>11</SP>/ 12  secs. The seventy-first tick of a timepiece having zero inaccuracy and this nominal rate will thus occur after exactly 11<SP>10</SP>/ 12  secs and the seventy-second tick after exactly 12.0 secs. Thus the waiting time corresponds to 85, 800 cycles, which gives a maximum measuring range of 600 secs. per day deviation. In the case of any of the above nominal rates but an error of less than 600 secs. per day, the tick immediately preceding the waiting time of 11<SP>11</SP>/ 12  secs will always be an odd-numbered tick,whilst the ensuing, last tick which terminates the count will always be even-numbered. The ticks, which may be picked up in the usual manner by a microphone, are converted to voltage pulses of short duration which are amplified and applied to a frequency generator feeding a counter through a controllable electronic gate. An impulse from the counter after 85, 800 cycles unlocks the apparatus so that the next tick terminates the measurement.

Abstract: 765,421. Magnetic couplings. GENERAL ELECTRIC CO. March 1, 1955 [March 1, 1954], No. 6072/55. Class 35. [Also in Group XIX] In an eddy current coupling used in a speedometer the effect of temperature variations is compensated by providing in the field structure of the coupling a bimetallic element which alters the coupling air gap with the ambient temperature. Fig. 1 shows a speedometer having a synchronous motor driving the primary member 17 of an eddy current coupling whose secondary member 28 is connected to the speedometer pointer 4. The coupling member 17 consists of two sets of axially polarized permanent magnets 21, 22, carried by end-plates 18, 19 which are separated by thin members 20. The plate 18 consists of two laminµ 29, 30 having different thermal expansion and one of them is of magnetic material. Any temperature variation will cause corresponding variation in the air gap length as seen in Fig. 3. Also a temperaturecompensating magnetic shunt disc 23 is mounted relatively to the supporting plate 19 and the disc 23 is shaped to fit around the magnets 22. This magnetic shunt may take the form of an axially movable member 37, as in Fig. 5 (not shown).

Feb. 26, 1935, No. 6128. Convention date, March 3, 1934. [Class 40 (iv)] In a vibrationtranslating device such as a pick-up for sound records in which the low frequencies are attenuated, a damped resilient connection is provided between the magnetic system and the vibrating armature or coil such that at low frequencies, e.g. at 50-100 cycles per second, the magnetic structure vibrates out of phase with the vibrating armature or coil, increasing the relative velocity of the generating element with respect to the field and so increasing the output. In addition, the magnetic structure may be mounted on a damped resilient support. As shown in Figs. 1 and 3, a coil 18 moving in the annular gap between poles 22, 23 of a magnet 15 is carried on one end of the L-shaped stylus arm 19. The pivot 20 of the stylus arm is mounted in a rubber bearing between brass plates 27, 28, the plate 28 having a forked arm 281 which extends on each side of the stylus arm to form a guard. Additional damping for the stylus arm is provided by a rubber pad 30 pressed against a rod or wire 32 on the stylus arm by a cover-plate 31. The frame 16 which carries the magnet 15 may be mounted on a thin flexible plate 33 and its movements damped by a rubber pad 34 secured to the frame 16 and the support 161. Formulae are given connecting the relative velocity of the generating elements with the velocity of the stylus tip and the mechanical constants of the reproducer, and the selection of suitable mechanical constants is discussed.

[Also in Division H2] A control system wherein the power supplied to a load is determined by the number of pulses in a pulse train comprises means for generating a stream of regular pulses which are independent of the load power requirement, digital means for providing from the pulse stream a number of separate pulse trains and contactless selector means for selecting and combining the separate pulse trains in combinations which control the power supply to the load. The load may be a cooking apparatus such as an oven and the selector means may be manually operated or automatically operated by a sensor which may be a bi-metallic strip, a pressure-sensitive bellows. Alternatively a motor-driven programming device may be used as a selector means. The power supply to the oven may be controlled by way of a thyristor or a triac the triggering signals for which are provided by the pulses in the combined pulse train, each pulse triggering the thyristor into conduction for one half cycle of the A.C. supply. The regular stream of pulses is generated from an A.C. supply by means of a rectifier, zener diode clipper arrangement together with an inverter-amplifier device, the pulses occurring at the supply frequency at null points in the supply. These pulses are supplied to a plurality of flip-flop devices and AND-gates whereby separate pulse trains are produced each of which has a waveform which is twice as long as that of the preceding train. The separate pulse trains are fed to a contactless selecting device whereby the pulse trains can be selected and combined to produce a pulse train which is used to control the power supply to the load. The selector device may comprise variable transformers, variable capacitors, variable inductors or light-sensitive elements. Furthermore the output pulse train may be arranged to have one interval which does not contain a pulse and this interval may be used for detecting abnormal conditions in the system. An alternative embodiment shows the separate pulse trains derived from clock pulses using shift registers and a flip-flop device.

Abstract: 665,017. Coin-operated apparatus for vending liquids. ELLIOTT, A. C. March 10, 1949, No. 6594/49. Class 27 In a coin operated mechanism for filling lighters with fuel a piston is automatically operated by insertion of a coin to force a charge of air under pressure into an auxiliary chamber fed with fuel from a supply tank so that the fuel in the auxiliary chamber is forced into a delivery chamber from which it may be discharged for use. Coin action; thrust, weight. In Fig. 1, a coin inserted in a coin shoot (not shown), presses aside a pin 17 on a lever 7 pivoted at 16 to a plate 5 and carrying teeth 21a engaged by a bent portion 21 of a lever 18 pivoted at 19 and urged by a counterweight 20 to retain the lever 7 in its displaced position. Two levers 14, 15 secured to the lever 7 carry a pin 11 working in a slot 13. The pin 11 engages under a lever 10, Fig. 2, pivoted at 16 on the opposite side of the plate 5 and engaging a groove 12 in a piston 9 working in an air cylinder 8 to raise the piston and draw air through a non-return ball valve in the base of the cylinder. As the coin falls through the coin shoot it strikes the bent end 21 of the lever 18 to release the lever 7. Delivery of liquids. When the lever 7 is released the piston falls under its own weight and forces air from the cylinder through a pipe 25 to raise a valve 28, Fig. 1, so closing channels 27 between a reservoir 1 for lighter fuel and an auxiliary chamber 26.' The fuel in chamber 26 is then forced by the air through a pipe 29 to a delivery chamber 6, fuel above a predetermined volume being returned through an overflow valve 36 and pipe 34 to the reservoir 1. A spring-biassed valve 31 may then be opened to deliver the fuel retained in the delivery chamber 6 through a nozzle 30. A drip tray 37 below the nozzle 30 is connected with the reservoir 1 by a pipe 38 formed with an S-bend and provided with a piece of wire gauze 39 to prevent any flame striking back to the reservoir. Instead of fuel flowing directly to the chamber 26 as shown, it may be sucked into the chamber by the upward movement of the piston 9. Specification 631,513 is referred to.
