Title: An improved resonance relay operating according to the ferraris principle
IPC: H01H51/32
Filed: 1931-08-29
Abstract: 382,981. Induction relays. LANDIS ET GYR SOC. ANON., 1, Hofstrasse, Zug, Switzerland. Aug. 29, 1931, No. 24349. Convention date, Sept. 2, 1930. [Class 38 (v).] An inductiondisc relay has two driving fluxes s produced by currents flowing in two circuits tuned to different operating frequencies, these fluxes coacting with a third flux produced by current in a third circuit tuned to a frequency intermediate the two operating frequencies so that when one of the operating frequencies is transmitted the disc is turned in one direction and when the other operating frequency is transmitted the disc is turned in the other direction. As shown in Fig. 1, two parallel tuned circuits 7, 8 have their inductances 101, 10<11> wound on the two limbs 2<1>, 2<11> of a driving magnet 1 for the disc 5, the two circuits being arranged to resonate at two operating frequencies which may be separately superimposed on supply mains. A series resonant circuit 6 is connected to the mains and has its inductance 10 wound on the return limb 2 of the magnet 1 so as to be inductively related to the windings 10<1>, 10<11>, the circuit 6 being tund to a frequency intermediate that of the circuits 7, 8. The windings are thus arranged so that motion of the disc is produced in one direction when the relay is fed by current of one operating frequency and in the other direction when fed by current of the other operating frequency. In a modified form, Fig. 2, in which a three-limbed driving magnet is employed the parallel resonant circuits 7, 8 are connected in series with the series resonant circuit 6 to the supply mains, the inductances 10, 101, 10<11> of these circuits being wound on the limbs 2<1>, 2<11>, 2<111> of the magnet. In a further similar modification, Fig. 3 (not shown), three series resonant circuits are employed. The relay may be used for changing over multiple tariff electricity meters or for performing definite operations in electric clocks, the relay being set in operation for this purpose by controlling currents sent out from a central station.

Filed: 1974-06-03
Abstract: 1467730 Television systems QUANTEL Ltd 22 May 1975 [3 June 1974] 24421/74 Heading H4F An arrangement for comparing the phase of Write and Read clock phase identity signals in a television video time base corrector comprising a number of stores fed, for example, from a digital video tape recorder, includes means which provide in-phase and anti-phase Write phase identity signals, one or other of the signals being selected by the output of a comparator which compares the selected signal with the Read phase identity signal. The circuit shown, Fig. 1, receives an analog video input, for example derived from the output of a tape recorder, and provides start pulses at output 20 to start a triggered oscillator controlling the stores. The colour burst is extracted by filter 10 and gate 11, and in-phase and anti-phase zero-crossings Q, Q are derived from the burst by unit 12. One or other of Q, Q is selected by switch 13, under the control of the arrangement according to the invention, and passes to unit 14 together with a horizontal sync pulse extracted from the video signal. Unit 14 feeds a differentiator and inverter 18 to provide the start pulse. Horizontal sync pulses are obtained from the input video via sync pulse separator 24, delay 19, and phase locked loop 26. Divider 25 delivers in-phase and antiphase half horizontal frequency square wave signals to selector switch 22 which, under control of a comparator 28, selects one or other of the square waves to control switch 13. The selected square wave represents the Write phase identity and is fed to the comparator via a latch 30 gated by quarter line frequency pulses, assuming there are four one-line stores, which bear a fixed phase relative to the Write pulses of one of the stores. The Read phase identity signal is derived, Fig. 2 (not shown), from a sub-carrier reference signal and a horizontal sync pulse reference signal by way of frequency dividers and a latch (35) gated by quarter line frequency pulses which bear a fixed phase relative to the Read pulses of the said one store.

A float valve wherein the effective weight of the float is at its greatest at the beginning of the opening movement and the effective buoyancy is greatest at the beginning of the closing movement. The valve comprises a flexible valve member 13 and a float 14 including a hollow chamber 22 having an air vent 23 situated above the level of a fluid passage 24, a second sealed chamber 21 may also be provided. The cross-sectional area of the opening 24 is such as to permit fluid to pass in and out of the chamber at a rate lower than the rate of rise and fall of fluid in the vessel 10. The flexible valve member 13 is fixed at one end to the vessel 10 and has at its other end a latch bar 16 projecting through a slot 17 in a rigid float arm 18. As the level of fluid in the vessel rises the float arm 18 bears against a seating 15 and holds the flap 13 against the opening of a breather or fluid inlet pipe 12. If the fluid level falls the combined weight of the float and of the fluid in chamber 22 rotates the float clockwise until it rests against a stop 26. Meanwhile the fluid drains out of the chamber 22 at a predetermined rate. If the density of the fluid in which the float is immersed changes sufficiently, e.g. by raising its temperature the valve will open and cold fluid may be admitted in order to regulate the temperature of the fluid. The valve finds particular application in the headers of heat exchange elements or in the coolers of dry cooling tower installations.
