Title: Improvements in and relating to coin freed mechanism for electricity and similar meters
IPC: G07F15/00
Filed: 1933-10-07
Abstract: 426,953. Prepayment mechanism for meters. UNITED GAS INDUSTRIES, Ltd., 51, Lincoln's Inn Fields, ANGOLD, H. E., and CHRISTIAN, A. J., Meter Works, Rowan Road, Streatham Vale, both in London. Oct. 7, 1933, Nos. 27688/33 and 28808/34. [Class 27] [See also Group XXXVI] In meter prepayment mechanism, rotation of a coin-holder h sets a supply element through a train of gearing driving an interrupted pinion, and sets forward quantity mechanism through change - speed gearing by an amount proportionate to the value of the coin inserted. As shown, the coin holder mechanism is of the type described in Specification 400,636, and drives an epicyclic reduction gear comprising a planet carrier c<1> fast with the quantity wheel operated by the coin of lower denomination, a sun-wheel c fast with the other quantity wheel, and a driven sun-wheel c<4> connected by gearing f, f<1> f<1>, f<3>, g to a sun-wheel h of the differential quantity mechanism. A toothed wheel d, fast with the planet carrier c<1> and the quantity wheel operated by both coins, drives through a pinion d<1> an interrupted pinion d<2> on the setting shaft of the switch mechanism, the teeth of the pinions d<1>, d<2> only being in engagement when the switch is tripped. The epicyclic reduction gear may, alternatively, be constructed as in Specification 392,530, and the interrupted pinion operated directly from the rotary carrier plate of the coin holder. The quantity mechanism further includes a meter-driven sun-wheel h' and planet pinions h<2>, h<3> in a carrier on a central shaft operating the switch tripping mechanism. This shaft is geared with a further shaft acted on by a spring which is tensioned during prepayment and assists the meter mechanism in operating the prepayment mechanism. In order to prevent over-winding of this spring, a pin m<4> on a wheel m<2> of an indicator showing the units unused tilts a lever s to move an obturator t over the coin exit slot a<1> of the coin-drum. Price - changing mechanism.-The meter drives the sun-wheel h<4> through the counting mechanism o, which is removably secured to projections on the casing by slotted lugs o<1> and screws o<2> and through change-gear mechanism of the type described in Specification 308,557, [Class 27], comprising a pair of plates k<2> rotatable about a central shaft k so as to bring alternative gears carried on countershafts p, q, r carried by the plates into mesh with a pinion o<6> or wheel o<5> of the counting mechanism, and thereby to provide three gear ratios with the central shaft k, which drives the sun-wheel h<4> through gears k<1>, j<1>, j. Indicators.-Shafts m, m<1> of an unused units indicator gear with a shaft n<1> driven from the planet carrier of the quantity mechanism. Specifications 308,401, [Class 27], 387,678, 393,975, 394,329, 405,302, 416,570, and 426,952 also are referred to.

Abstract: 698,686. Protective cut-out arrangements. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Nov. 9, 1951 [Nov. 13, 1950], No. 27694/50. Class 38 (v) [Also in Group XXXVI] In alternating current protective apparatus wherein the secondaries of plural current transformers are connected in a current balance circuit with one another and with a relay load providing control in accordance with current conditions, a capacitance is connected across the secondary windings of such value as to pass a leading current opposite in phase to the magnetising currents of all the transformers, whereby the load current is lagging compensated for the distorting effect of the magnetising currents on the relationship between the load current and the primary currents, and for its own lagging component when the relay load is inductive ; whereby the primary current sensitivity of the arrangement is increased. Fig. 4 shows a balanced earth fault protection system wherein three current transformers whose primaries are the busbar conductors 17, 18, 19 of a 3-phase circuit and whose secondaries are connected in parallel with the operating coil of a relay 25 and the secondary 23 of a fourth current transformer whose primary is the earth conductor 24 of the circuit. A compensating capacitance 26 across the relay coil takes a leading current counterbalancing the several lagging magnetising currents of the current transformers and also the feedback of magnetising current from the transformer carrying the largest primary current into the remaining transformers. Fig. 5 shows a busbar protective system wherein plural 3-phase feeders 27, 28, 29 connected to busbars 30 energise corresponding 3-phase current transformers whose respective secondary windings are parallel connected in groups 31, 32, 33, 34, 35, 36; and 37, 38, 39, each of which has a parallel capacitance 43, 44, 45 compensating for the lagging magnetising currents of the associated transformers. The groups are connected in parallel across a relay operating coil 42 responsive to the difference between the currents into and out of the busbars, and a capacitance 46 across the relay compensates for the lagging component of the operating current therein. The several capacitances may be concentrated into a single capacitance. Specifications 298,994 and 298,995, [both in Class 38 (v)], are referred to.

Title: Compositions having lubricating properties
IPC: C23C22/00
Filed: 1950-11-27
Abstract: A lubricating composition comprises a major proportion of a hydrocarbon oil, thickened with a minor proportion of a colloidal gel, of aerogel structure, of a metal sulphide having a water solubility of less than 0.0005 grams per 100 cc. of water at 20 DEG C. The composition may be a thixotropic gel or a grease.  Sulphides referred to are mercury, lead, copper, bismuth, cadmium, arsenic, antimony, tin, iron, nickel, and cobalt sulphides.  The hydrocarbon oil may be a petroleum oil which may be a lubricating oil, kerosene, stove oil or gas oil, or a synthetic oil such as polymerized olefins. Various processes for preparing the sulphide aerogels are described, including the transfer of a hydrogel of the sulphide into a hydrocarbon oil by milling in the presence of surface-active agents, such as high molecular weight amines, amine salts and quaternary ammonium compounds, for example, heptadecylamine, heptadecylimidazoline, and amido amines of diethylenetriamine and oleic acid; glycerine monostearate and soaps such as ammonium-12-hydroxy stearate, lead oleate and diethanolamine oleate may also be used.  Soaps or other inorganic gelling agents may also be added to the composition, such as aerogels of silica, alumina, aluminium silicates, alkaline earth oxides and hydroxides such as magnesia and lime, and clays such as bentonite and hectorite which have been subjected to ion-exchange with cationic surface-active agents such as dimethyl-dicetylammonium chloride.  In one example, an aqueous gel of ferrous sulphide is prepared and washed with methyl alcohol. The resulting alcogel is mixed with mineral lubricating oil, the mixture heated to remove alcohol, and then milled to form a grease.

Abstract: 682,962. Retarding action of switches. BRITISH THOMSON-HOUSTON CO., Ltd., and GIBSON, A. C. Sept. 13, 1950 [Nov. 1, 1949), No. 27974/49. Drawings to Specification. Class 38 (v) [Also in Group XXXII] A dashpot (see Group XXXII) for providing a time-lag in the operation of over-current electric protective devices, which is normally an inverse function of the force applied to the dashpot piston by the armature of a relay forming the device, is so constructed as to produce a change in the function and a consequently reduced time-lag when the applied force exceeds a predetermined amount. The armature is associated with contacts which when closed, effect energisation of the trip-coil of a circuit breaker, or may be directly associated with the trip coil itself. Where the devices are connected in series a measure of discrimination in deciding the circuit-breaker to be tripped, is obtained, both for over-load currents and currents of short-circuit magnitude.

Abstract: 695,430. Saw-tooth generating circuits. EDISON SWAN ELECTRIC CO., Ltd. Nov. 29, 1951 [Dec. 6, 1950], No. 28043/51. Class 40 (vi). In a circuit for generating push-pull saw-tooth waves which are balanced with respect to a point of reference potential, comprising two capacitors in series arranged to be periodically charged and discharged, the junction-point of the two capacitors is connected to the reference point through a resistor and capacitor in parallel and arranged to maintain the junction point at a potential which tends to equalize the charging rates of the two capacitors. The capacitors 1 and 2 are charged from positive and negative voltage sources through resistors 3 and 4, respectively, until the breakdown potential of thyratron 9 is reached, when they are rapidly discharged. Normally no current passes through capacitor 5 and resistor 6 but if the charging current of one capacitor increases or decreases a voltage is produced across capacitor 6 which tends to equalize the charging rates and thus to equalize the voltages applied through R.C. coupling networks 19, 21, 20, 22 to the output. A potentiometer 17 adjusts the output amplitude and synchronizing pulses may be applied to the control grid of the thyratron.

Abstract: 914,064. Washing granular materials. STAMICARBON N.V. Dec. 2, 1959 [Sept. 2, 1958], No. 28210/58. Class 82 (2). In a sink and float process a mixture of materials of different specific gravity is separated into coarse and fine fractions, the coarse fraction is then separated into fractions of different specific gravity by treatment in a suspension of magnetizable particles and the fine fraction is separated in a liquid medium of lower specific gravity than the first suspension, the coarse particles being washed with water from the fine fraction separator and the magnetizable particles recovered by a magnetic separator for recirculation to the coarse fraction separator, and the non-magnetizable particles and liquid recirculating to the fine fraction separator. As shown, a coal feed of size up to 7 inches is wet screened at 1 and the coarse fraction is separated in a suspension of magnetite in a sink and float separator 11. The coal floats are screened at 12 and rinsed by sprays 13 and the sinks are screened at 16 and washed by sprays 17, the magnetite rinsings collecting in tanks 15 and 18 and passing to a magnetic separator 21 the magnetic fraction being recirculated to separator 11 and the remainder passing to sprays 2. The fine fraction from the raw coal feed passes from 1 to a jig 4 and the washed fine coal is dewatered on screen 6 and discharged at C while the underflow from 6 separates in cone 8 into a sludge D and the clear water overflow is partly returned to the jig 4 and also to the sprays 13 and 17 which wash the floats and sinks from the separator 11. If the screen 1 operates dry the non-magnetic particles from the magnetic separator 21 by-pass the screen, as shown at 24. In an alternative embodiment (Fig. 2, not shown) the jig 4 is replaced by a froth flotation plant. Specifications 791,520, 791,857, 791,858 and 791,859 are referred to.

Abstract: 1330599 Electro-chemical analysis BOEHRINGER MANNHEIM GmbH 16 June 1972 [18 June 1971] 28230/72 Heading G1N The invention relates to a process for the quantative determination of substances by catalysis by an enzyme in an oxygen containing solution and measuring the variation of oxygen content electro-chemically. An air-bubble-free "block" of sample solution is introduced into a stream of buffer solution having a known oxygen content, and flowed over a carrier-bound enzyme. As shown FIG.1, a reservoir of buffer solution oxygenated by an air-bubbler-pump M is circulated by a pump P through a sample applicator A an enzyme-column S and electrochemical cell D and returns to the reservoir. The sample applicator Figs.4 comprises a slide-valve 17 with a bore 18 into which the sample is introduced through a funnel 21. The slide is then moved to bring the sample into the buffer solution stream flowing in pipe 12. At the same time suction from pipe 16 via bore 19 cleans the funnel. After measurement bore 18 is moved into line with suction pipe 16 to remove the buffer solution in it. The main pipe 12 is closed but buffer solution continues to circulate through the branch-pipe 13. The sample applicator may alternatively be formed as a multi-bore rotary stop-cock. The enzyme carrier may be that described in German Specification 1908290; the peristaltic pump P that described in German Specification 2025056. Any suitable electro-chemical oxygen sensor may be used. Applications determination of blood sugars, uric acid, nucleoside bases, and inorganic peroxides and hydrogen peroxide (using catalase).

Abstract: 1,219,152. Well packers. CAMCO, Inc. 13 June, 1968 [30 June, 1967], No. 28271/68. Heading E1F. A well packer comprises a mandrel 22, packing seals 18, slips 74, hydraulically operable seal expanding means including a sleeve 56 and a seal setting sleeve 44, and a one-way clutch 53 between sleeve 44 and the mandrel to keep sleeve 44 in position to maintain the seals 18 expanded independently of the slips. To set the packer a plug is inserted in the mandrel beneath the slips, and fluid pressure is applied to the mandrel and chamber 31. Pressure in the chamber first causes pin 68 between the two sleeves to shear and then forces piston 60 and sleeve 56 downwardly to expand the slips. A sleeve 78 is slidably mounfed on the mandrel and has ears 80 extending into slots 82 in the slips 74 to prevent one slip from moving longitudinally with respect to the others. After the slips have been expanded and the pressure in chamber 31 increased, shear pin 70 between seal setting sleeve 44 and a sleeve 36 breaks allowing piston 48 and sleeve 44 to move upwardly to expand the packing seals 18. Clutch 53, which prevents downward movement of sleeve 44 and clutch 66 which prevents upward movement of sleeve 56 relative to sleeve 44, are of the construction described in Specification 1192306. To release the packer, top sub 90 is rotated shearing pin 100 and raising the sub and member 94 until shoulders 102 and 104 on member 94 and sleeve 92 engage whereupon sleeve 92 is also rotated to raise the upper abutment of the packing seals. Further upward movement of sleeve 92 and sleeve 36 connected thereto causes shoulders on sleeve 36 and 44 to engage to raise sleeve 44, and then shoulders on sleeves 44 and 56 to engage to raise sleeve 56 and to release the slips. Bow springs 84 on the slips ensure that the slips are retracted an appreciable distance. Initial rotation of the sub connects the inside of the mandrel to the outside of the sub through port 91. The slip and the packer release assemblies are described . in Specifications 1175033 and 1219153.
