Title: Improvements in or relating to electric switchboard indicating or mimic diagrams
IPC: H02B15/00
Filed: 1932-10-12
Abstract: 408,634. Diagrams. CHADWICK, J., 1, East Drive, Longford Park, Chorlton-cum- Hardy, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Oct. 12, 1932, No. 28487. [Class 146 (ii).] In an electric-switchboard mimic diagram, in which switches &c. are represented by holes, slots, or other suitable apertures in a board, interposed in the lines of circuit representations, the slots &c. being illuminated by lamps disposed at the rear of the board, there are interposed between the apertures and the lamps screens of different colour, for example, red and green, which are mounted on a common carrier, movable manually from the front of the board about an axis perpendicular to the plane of the board so that the screens can be caused to cover the aperture one at a time so as to indicate by their colour the condition of the particular switch &c. which the aperture represents. The circuit is indicated by painted lines or by strips of aluminium 3, 2 mounted upon a black panel 1, the strip 2 representing a switch; the panel is formed with a circular aperture or a slot 5 surrounded by the strip 2, behind which is provided a sector 6, carrying a red and a green screen 7, 8, and pivoted on a pin which is rotatably mounted in a flanged bush 10 and is formed with slots 12 for engagement by a two-pin key to rotate the sector. A pair of stops 13, 14 limit this movement, and lamps are arranged behind the screens so as to illuminate the slot 5 with red or green light according to the position of the sector which is manually adjusted to indicate whether the switch is on or off. In a modification, the pivot pin carries a projection to which is attached a pin projecting through a slot in the panel 1 and which may be moved to rotate the sector 6. If circular apertures 5 are employed, the screens may be rendered opaque over a part of their surfaces so that only a relatively thin line of light is provided, which may be of one colour and in alignment with the run of the bar when the switch is closed, and of a different colour and inclined to the bar when the switch is off. The sector may be activated by a pin carried by the circular strip 2, which is then rotatably mounted on the panel, and the strip 2 may carry an opaque plate formed with a diametrical slot or transparent strip extending across the circular aperture in the panel, which aligns with the bar 3 when the switch is on and is inclined thereto when the switch is off.

Title: Improvements in or relating to electro-magnetically driven pumps
Inventor: CHAUSSON ANDRE
IPC: F04C29/00
Filed: 1958-09-08
Abstract: 874,489. Reciprocating motors. USINES CHAUSSON S.A., DES. Sept. 8, 1958, No. 28724/58. Class 35. [Also in Group XXVI] A pump or compressor, e.g. for a refrigerator, is driven by a cylindrical, polarized armature which oscillates between alternating electromagnetic poles. The natural frequency of oscillation on no load is slightly below the energizing frequency and is controlled by an elastic member attached to the armature. As shown in Fig. 1, this consists of a spiral spring 31, and the armature 22 includes two permanent magnets 23, 24 arranged with unlike poles adjacent. The magnets have pole tips 25 wider than the gaps between the limbs of E-shaped laminated electromagnets 5, 6 so that in the rest position the electromagnets act as keepers. When the windings 16, 16a are energized with A.C. the resultant oscillations of the armature are transmitted to a piston 39 which operates in an arcuate cylinder 42. This is separated from a chamber 41a by a flexible cup valve 43. The whole device, on a moulded base 1, is suspended from an outer case 9 by springs 7. In an alternative arrangement, two or four pistons may be provided, the spiral spring may be replaced by a central torsion member passing through a hollow armature shaft, and the electromagnetic field may be of an eight-pole construction, in which case the armature has four permanent magnets. As shown in Fig. 5, alternate field poles carry windings, but alternatively every pole may be wound.

IPC: H01J47/04
Filed: 1949-11-10
Abstract: 652,213. Electrostatic instruments. BRITISH OPTICAL & PRECISION ENGINEERS, Ltd. Nov. 10, 1949, No. 28840. [Class 37] [Also in Group XXII] An electroscope has an electrode assembly enclosed within an ionization chamber and consisting of a quartz fibre mounted on and supported by a wire, the fibre being inserted in slots made in the wire which are subsequently clinched in order to retain the fibre firmly in position and in good contact with the wire. Within an aluminium tube 1, Fig. 1, is mounted an optical system consisting of an eyepiece lens 2 and an objective lens 3 with a graticule 4 mounted between them so that the lens 3 forms an image of the electrode assembly 5 on the graticule 4. The electrode system 5 is contained within an ionisation chamber 6, the walls 7 of which are made from a graphited phenolic moulded product. The electrode system 5 consists of a quartz fibre 8 mounted on an aluminium supporting wire 9 which is embedded in a polystyrene or acrylate insulator 10. The end 11 of the wire 9 protrudes through the insulator 10 and is contacted by a plunger 13 in the charging position. An end cap 14 retained by a spring 15 is removed to permit a charging unit to be pushed in for charging the electroscope. Should the instrument be exposed to Gamma or X-radiation, the leakage of the charge is a measure of the amount of exposure and is indicated by movement of the quartz fibre image across the graticule. The wire support 9 is shown in Fig. 3 before the insertion of the quartz fibre 8 and before being bent to the final arcuate form shown in Fig. 1. This is placed under a cutter, Fig. 4, consisting of a blade 17 mounted in a carrier 18 which is pivoted at 21 and has a stop 22 to determine the depth of the cut. A slot 20 is cut in each leg of the support 9 by depressing the carrier 18 against the stop 22. A quartz fibre 8 is then laid across the aluminium wire 9, as shown in Fig. 5, and subsequently inserted into the slots 20, the lips 23, 24 of which are closed to clinch the fibre 8 to the wire 9. The wire support 9 is then bent to its final arcuate shape by means of a jig. The cutter may alternatively be so pivoted that it has a scooping action which forms only one lip 24 to each slot.

Abstract: 696,436. Current measurements. DOBBIE McINNES, Ltd. Nov. 21, 1951 [Nov. 27, 1950], No. 28898/50. Class 37. An ammeter is corrected for variations in frequency of the supply by applying to it three voltages, the first being derived from the supply voltage and varying with the frequency, the second voltage being independent of frequency variation and correcting the error in the first due to variations in supply voltage, and the third being a bias voltage independent of variation in frequency and supply voltage and of such a value as to cause the resultant voltage from these three components to be zero at a predetermined standard frequency. The current to be measured, which may be that taken by a motor driving vanes in a viscous liquid for measuring its viscosity, is fed through an instrument transformer 2 and a rectifier 3 to an artificial load R. Three compensating circuits 4, 5, 6 are fed from the supply voltage through transformers. The circuit 4 is a resonant circuit including an inductance L and condenser C and feeds a load V1 through an instrument transformer 7 and a rectifier 8. The circuit 4 is tuned to a frequency somewhat higher than the maximum probable variation. The circuit 5 feeds a non-reactive load V2 through a rectifier 9, while the circuit 6 feeds a load V3 through a rectifier 10 and a bridge including two barretters B. A moving coil meter 11 is connected with the load R and the compensating loads V1, V2, V3.

Title: Improvements in process of gold refining
IPC: C25C1/20
Filed: 1936-10-26
Abstract: 483,741. Electrolysis. BLAUT, S. J. Oct. 26, 1936, No. 29102. Convention date; Oct. 25, 1935. [Class 41] In the parting and refining of gold from an impure gold anode, the gold is electrolytically dissolved in a bath initially comprising concentrated hydrochloric acid free of gold salts. The current density may be between 100 and 900 amperes per square foot, and an alternating current may be superposed to prevent polarization. The concentration of the acid may be restored as it is consumed, and an alkali or alkaline earth chloride may be added to the bath. The temperature may be maintained below 35‹ C. The gold content of the anode may be as low as 4 per cent. The gold deposits on the cathode as a loose spongy mass which drops off and falls to the bottom of the bath. In refining gold parted by the method of the invention, the silver present as chloride may be removed by treatment with ammonia, or sodium thiosulphate, by reduction and solution in nitric acid, or by melting the deposit and floating off the silver chloride, Or the deposit may be dissolved in aqua regia, the nitric acid driven off, the silver precipitated by hydrochloric acid, and the gold then precipitated by adding a reducing agent. Alternatively, the deposit may be refined by electrolysis, using a chlorauric acid bath. After removal of the silver chloride, the deposit may be refined by electrolysis as in parting, the gold being obtained wholly or in part as a solution..

Abstract: 305,159. Lumsden, G. H. C. Nov. 1, 1927. Stoppers with valves.-In a closure for water bottles, bags, &c. providing separate passages for air and liquid and comprising a ferrule 4 and stopper 1, the ferrule is formed with a shoulder 4<b> or other holding means and the stopper with a resilent member or wire 2 disposed in a groove 3 extending partly around a portion of the stopper, the arrangement permitting the stopper to be screwed into the ferrule to a position where the wire passes below and extends beneath the shoulder. From this position the stopper can be screwed further into the ferrule to close the bottle or unscrewed for the passage of liquid but the complete withdrawal of the stopper from the ferrule is prevented by the engagement of the wire 2 with the shoulder 4b. Alternatively, the shoulder may be provided on the stopper and the resilient member on the ferrule. When the stopper is unscrewed, the resilient wire 2 is forced by the shoulder 4<b> into a groove 5 beneath the groove 3, normally this groove is too shallow to permit the wire to embed itself .deeply enough therein, but in a modification the groove 5 is cut more deeply and it is possible, after the engagement of the wire and shoulder has indicated that the normal withdrawal point has been reached, for the shoulder to force the wire into the groove and permit the complete removal of the stopper when sufficient force is applied. The invention may be applied to the closure described in Specification 301,135 and comprising longitudinal ribs 1<a> with intervening slots and a central air passage, the wire being secured to one rib and the grooves being formed in an adjacent rib. Fig. 6 shows a modification in which a slotted member 6 depends from a V-shaped groove 7 in one of the ribs 1<a>, the member being held parallel to the axis of the stopper by the threads 4a of the ferrule during the insertion of the stopper but canting outwards as soon as it is clear thereof. By tilting the bottle, complete removal of the stopper is possible. In other forms, a bent wire is pivoted beneath the groove 7 or a. spring tooth member engages in a recess in the stopper.
