IPC: G01R11/56
Filed: 1963-11-21
Abstract: 1,103,763. Counters. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 23 Nov., 1964 [21 Nov., 1963], No. 46045/63. Heading G4D. [Also in Division G1] An electricity meter for registering, in addition to the total quantity consumed, the quantity consumed at a rate of consumption in excess of a predetermined rate detects the rate of consumption by comparing the repetition frequency of electrical pulses generated in response to the rate of consumption with a reference frequency representative for the predetermined rate. The rotor disc 4 of an induction-type motor meter 1 produces pulses at a rate proportional to the speed of rotation of the disc, either by the cam-and-switch arrangement 7, 8 shown or by the use of a slotted disc rotating between energized and feedback coils of an oscillator which produces a train of pulses at a rate dependent on the speed of the slotted disc. The slotted disc may be coupled with the rotor disc 4 or the disc 4 may itself be suitably slotted. The pulses control the speed of rotation of a motor 9 and a fixed speed motor 15 is driven at a rate corresponding to the reference frequency. At the predetermined rate of consumption gearwheels 11 and 14 rotate at the same speed in the same sense; at lower rates the gear 18 is driven in a sense such that the gear 19-which is of pawl-and-ratchet type-does not drive the register 16, but at higher rates the register 16 is driven. A second set of gears 25, 26, 27 and associated register 23 may be similarly controlled by motors 9 and 15, but through different ratio intermediate gears, to register consumption at a rate in excess of a second, and higher, predetermined rate. The registration of quantity consumed at an excess rate may be arranged to take place only during specified peak-load periods, a switch 13 completing the circuit to motor 9 only during these periods. This switch may be made automatically by the fixed speed motor 15. To allow for the possibility that power failures will cause the time-switching function of motor 15 to fail, the motor may incorporate a conventional spring-and-escapement reserve switching mechanism.

Abstract: 1484569 Extruding hollow, elongate articles INDUSTRY SECRETARY OF STATE FOR 9 Oct 1974 [10 Oct 1973] 47420/73 Headings B3A and B3P A method of making a hollow, elongate article includes hydrostatically extruding through a die 28 a billet which surrounds at least one elongate cavity 12 filled with a substance 14 having a hardness not greater than that of the billet and removing the substance from the billet during or after extrusion, the billet comprising at least two discrete parts and extrusion taking place in the direction of the longitudinal axis of the cavity. One form of billet comprises a discardable nose portion 48, Fig. 6, and an end closure 54 screwed on to a cylindrical body portion 50 which may be of copper while the portion 48 may be of aluminium. The billet may be filled with household salt which is easily removed from the extruded product, e.g. by hot water or steam. The billet may be formed into a fivelobed cam and the cavity may comprise between 2À8-25% of the cross-sectional area, Fig. 2 (not shown). Alternatively thin walled tubing of non- circular section or comprising a number of tubes nested within a larger diameter tube may be made as may a thick walled tube having a number of longitudinal ducts. The cavity or cavities are drilled in the original billet if they are of circular cross-section or the billet may be cast with non-circular cavity or cavities. A steel billet is filled with aluminium alloy and coated with zinc phosphate and stearate soap. Immediately before extrusion it is further coated with molybdenum disulphide and graphite grease. After extrusion the aluminium alloy is punched out or melted out preferably by passing an electric current through it. Alternatively the extruded billet may be immersed in a 20% solution of sodium hydroxide in water, which attacks the aluminium alloy at its interface with the steel so that only a small amount of the alloy need be dissolved. For long extruded products, the substance, e.g. lead or Woods metal, is melted by heating for removal. Materials which may be extruded include stainless and other steels, aluminium and its alloys, titanium, niobium and zirconium. The extrusion process may be assisted by drawing the billet through the die.

Abstract: 1398546 Electro-chemical analysis AUSTRALIAN ATOMIC ENERGY COMMISSION 23 Oct 1972 [21 Oct 1971] 48812/72 Heading G1N An irradiation dose is determined by subjecting a solution of ceric and cerous ions in the presence of sulphuric acid to gamma or electron radiation, producing a voltage proportional to the electrochemical potential between the irradiated solution and an unirradiated solution of ceric and cerous ions, and applying the voltage to an analogue computer which converts the voltage to a value directly proportional to the dose received by the irradiated solution. A platinum wire is dipped in a respective one of the two solutions and the potential #E developed across the two wires applied across the base emitters of a pair of matched transistors operating in the diffusion current region, the collector currents IC 1 , IC 2  of the respective transistors being related by where IC 2  is set proportional to CR which is a voltage proportional to [Ce3+] v/[Ce<SP>4</SP>+] v of the unradiated solution. Since IC 1  has a negative temperature coefficient and #E a positive coefficient variations in temperature are compensated for. The output IC 1  is added to a current proportional to unity by an operational amplifier and then applied to a multiplier to produce a divide function, voltages C 3 , C 4  proportional to [Ce3+] v and [Ce4+ ] v of the unradiated solution being added by the feedback of the operational amplifier of the divider circuit. The output voltage of the divider circuit, is then applied to an operational amplifier connected as a substractor and the output of which drives a voltmeter to give a direct linear readout in megarads. The initial cerous ions concentration is at least equal to the initial ceric ion concentration, a list of suitable values for various dose ranges being given, and is not less than 3 x 10<SP>-3</SP> molar to nullify the effect of impurities. A construction of a cell is shown.
