Patent GB-1482717-A (GB)
Title: Identification of phases in a three-phase alternating current supply
IPC: G01R29/18
Filed: 1974-10-23
Abstract: 1482717 Measuring phase ELECTRICITY COUNCIL 7 Jan 1976 [23 Oct 1974] 45864/74 Heading G1U To determine which phase of a three-phase supply is connected to a load, to determine distribution of loads amongst the three-phases, an optical pick-up is used to derive a signal from a light source forming at least part of the load, and the output therefrom is compared in phase to a reference signal derived from a known phase of the supply. In monitoring domestic installations, the reference signal may be received by radio, whereas for a localized system e.g. a factory site, the reference signal may be received by a wire or ultrasonic link. Alternatively, phase information may be transmitted at a high frequency signal along one or more phases, and the information detected using an inductive pick-up. To identify which subsystem is supplying the load, a chosen subsystem is instantaneously loaded e.g. by switching a thyristor, to cause a 5-10% drop in the phase voltage. A corresponding drop can be detected in the optical pickup output, and indicated. In normal operation, a phase shifter giving 0‹ or Œ 120‹, is switched until phase equality is detected. Extra phase shift may be provided if the load is not purely resistive.

Filed: 1967-10-13
Abstract: 1,205,612. Water heaters. CORY CORP. 13 Oct., 1967 [2 Dec., 1966], No. 46747/67. Heading F4A. In a water heater in which water poured into a reservoir 15 is delivered through an inlet pipe 14 to the bottom of a hot water storage tank 11 and displaces hot water through an outlet siphon 16, the pipe 14 has an opening 54 connecting the expansion space 53 of tank 11 to atmosphere. Tank 11 includes an electric immersion heater 13. When water is poured into reservoir 15, opening 54 is closed by the liquid flowing down pipe 14 and as the water level rises in tank 11, the space 53 becomes pressurized, thereby causing the siphon 16 to start operation before the water level reaches the top of the bend 52. Hot water delivery through a spray head 19 ceases when the water level in tank 11 drops below the inlet 50 of pipe 16. A branch 56 from pipe 16, which opens to atmosphere at 58 above the highest level of liquid obtainable in tank 15, assists in draining the pipe 16 when the siphon action terminates. The tank 11 and reservoir 15 are contained in a casing 21, the tank 15 being pivotable about the top of pipe 14 to a position projecting from the casing 21 to facilitate pouring water thereinto.
