IPC: H01F27/28
Filed: 1952-10-06
Abstract: 734,205. Transformers. ENGLISH ELEC. TRIC CO., Ltd. Oct. 2, 1953 [Oct. 6, 1952], No. 24961/52. Class 38 (2). A transformer of the kind having a highvoltage winding split into a number of seriallyconnected coils 3 ... 6 has each coil wound in two or more parts which form a single unit mechanically but are insulated from each other and are then connected in series for concerted magnetization of a magnetic core. Each coil is wound from two conductors 8, 9 laid on simultaneously the outer end of the conductor 8 being connected to the high-voltage terminal by a conductor 10. The inner end of the conductor 8 is then connected to the outer end of conductor 9, the inner end of conductor 9 finally being connected to the conductor 8 in the adjacent coil. By this construction the voltage between conductors and the selfcapacity between the parts of the coil are reduced. In another embodiment each coil is divided into three parts, and during winding one of the two conductors is broken at the centre of the winding to provide one full part and two half-parts which are then suitably connected.

Abstract: 263,561. Umpleby, F. Oct. 8, 1925. Producers; coking processes .-A gas generator for the continuous distillation and gasification of liquid or pulverized solid fuel comprises an externally heated retort down which the fuel is showered through an ascending stream of oxygen containing gas, such as steam, in which the residue is gasified and cooled while the steam or gas is heated. Lime or limestone may be pulverized and fed together with the carbonaceous materials. A separate generator may be used for the distillation and gasification stages and the hot gases leaving the apparatus may be used to heat water in a coiled tube in the outlet pipe. The liquid or pulverized solid fuel for heating the furnace is admitted thereto together with a primary air supply by nozzles 8, the secondary air entering by apertures 5 and being heated in an annular space 4 before entering the furnace through inlets 7. The combustion products heat the tube or receptacle 9 and to pass an outlet 11, and the ash, falling on to water pipes 12, is removed through an opening 13. The fuel to be gasified is supplied through an outlet 14 in a transporting stream of gas and enters the distilling zone 18. The volatiles are withdrawn through the tube 19 and the heavy undistilled particles fall through the gasifying zone 21 where they react with the steam injected through nozzles 32 and heated in the hot zone 22, the resulting gas mixing in the tube 19 with the distillates. The incandescent ash is cooled by passage through the steam screen 23, which is thereby heated, and is collected at the bottom of the generator from which it is removed by a compressed air injector. If a rich gas is desired the steam and air entering at the inlets 32 is restricted and the ungasified coke particles driven by the injector 26 and pipe 28 into the furnace. Catalytic materials such as chromium, nickel, platinum or tungsten may be added to the charge in the reaction tube. The unconsumed fuel particles at the bottom of the generator may be briquetted.

Title: A method of improving an electrically conductive connection
Inventor: BEER ERNST
IPC: H01H1/021
Filed: 1969-05-16
Abstract: 1,261,249. Electric couplings. E. BEER. 16 May, 1969 [17 May, 1968], No. 25197/69. Heading H2E. [Also in Division C7] An electrical connection between two metal bodies is protected from corrosion by coating one of the contact surfaces with a soft metal alloy before the connection is made, the hardness of the coating being less than half that of the coated body, as measured on the Moh's scale. On connection, the coating may be forced away from the contact surface but it remains at the edges and thus maintains a seal. The coating having a hardness of less than 2.5 Moh's, and being less than 1-5 mm. thick, is composed of Li, Bi, In, Zn, Sn, Pb or alloys thereof. The coating may be applied thermally or electrolytically in which case a high current density and temperature and a low pH or concentration of metal compounds causes hydrogen absorption and a coating #80% of the normal hardness. The coating may be applied to a bolt (Fig. 4, not shown) with a pointed end which projects into the bore of a terminal block and clamps a "sacrificial" magnesium anode. The anode is electrically connected to a surface which it protects from corrosion. Alternatively, the coating may be applied to a support and electrical connection for a zinc anode on the hull of a ship (Figs. 1-3, not shown). The anode is secured to a coated spring strip (4) connected to a coated point screw (5) and a magnet with ceramic magnet rings and coated steel pole shoes (3). The screw (5) and pole shoes (3) are clamped to and make electrical contact with the hull of the ship. In a further arrangement, conductive lengths of pipe having coated flanges at their ends may be locked together by nuts and bolts. The coating prevents corrosion at the joints.

Title: Device for measuring electrical resistances and its application to the measurement of temperatures
IPC: G01R27/10
Filed: 1946-08-23
Abstract: 630,687. Resistance measurements temperature compensation ; wire-wound temperature variable resistances. SENIGON DE ROUMEFORT, F. DE. Aug. 23, 1946, Nos. 25285 and 25286. Convention dates, Sept. 9, 1943 and March 1, 1944. [Class 37] [Also in Group XXXVIII] In a resistance measuring device for a resistance thermometer, the latter is shunted across one of the crossed coils of a quotient meter while a known resistance is shunted across the other coil. The two resistances are supplied from a constant current source, the deflection of the instrument being proportional to the ratio of the currents in the coils and therefore to the ratio of the resistances. Fig. 1 shows quotient meter coils c<1>, c<2> connected respectively in shunt with a thermometric resistance X and a comparison resistance Rf, each shunted coil being supplied with substantially constant current from source S through high resistances R<1>, R<2>. In the modification shown in Fig. 3, a pyrometer head contains the thermometric resistance X which is connected across coil c<1> of the quotient meter by leads ab, cd. A constant comparison resistance Rf is connected across coil c<2> in series with dummy leads ef, fg, similar to the leads ab, cd and arranged to compensate for temperature variations of the latter. The shunted coils are energized with a constant current through high resistances R<1>, R<2>, temperature variations change the value of resistance X, and the meter accordingly shows a deflection dependent on the temperature of the resistance X. Different temperature ranges may be covered by switching in different values of comparison resistance or pyrometer resistance, the temperature coefficient of the latter being similarly variable by switching. In modifications (Figs. 4 and 5, not shown) the shunted coils are supplied with constant current in series, and the instrument may be A.C. operated, the input to each meter coil being rectified. The unknown wire-wound thermometric resistance is of the cylindrical form shown in Fig. 2, wherein the wire 1 is stretched between pairs of refractory insulating washers 2, 2<1>, 3, 3<1>, 4, 41 spaced apart by a shaft 5 having coefficient of linear expansion equal to that of the wire. The Specification as open to inspection under Sect. 91 describes liquid level gauges wherein a mercury column varies the resistance of a wire connected in place of the thermometric resistance of the invention. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1497075 Liquid heaters PLESSEY CO Ltd 23 May 1975 [30 May 1974] 25371/74 Heading F4A [Also in Division F1] In a liquid heating and forced circulation equipment for central heating apparatus or pumping apparatus for raising subterranean water, a heating vessel HV is provided to heat the cold liquid entering at C which has been forced into the heating vessel HV by a reciprocating pump P driven by pump driving means S, B in dependence between the relatively low and the relatively high temperatures of the liquid. The pump driving means takes the form of a sealed bellows B containing a supply of evaporable working fluid F inside the bellows B whereby the bellows operates in response to the vapour pressure of the working fluid in dependence on the temperature of the working fluid. When heat is applied to the heating vessel HV heated liquid passes through connections ha, x1 in a valve V to a heat exchanger X and thence to the heated liquid supply H via valve connections x2, hb (Fig. 1). Actuation of the bellows B upwardly causes the valve levers v, l to rotate the valve in an anti-clockwise direction to reverse the flow connection and when the valve is returned to its original position the cycle is repeated. Fig. 4 illustrates an alternative embodiment wherein the heat exchanger takes the form of a copper plate X which closes the lower end of the bellows B. Hot and cold water alternately are passed into contact with the lower surface of the plate X, the upper surface being in contact with the working fluid F. The valve V is in the form of a disc having a single diametrical bore 2 which provides direct connection between parts ca and cb when the arcuately movable valve is rotated by the pin and slot connection 9, 15. The pump spindle 11 is actuated by a coupling bar arrangement S1, S2, S3 actuated by the bellows B.
