Abstract: 378,959. Charging batteries. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Vencill, A. L. ; 572, Briar Cliff Road, Pittsburg, U.S.A.) May 21, 1931, No. 15021. Convention date, June 26, 1930. [Class 38 (iv).] In apparatus for charging a battery an arrangement is provided for increasing the rate of charge of the battery after a failure of supply has occurred. A battery B supplying a load L is charged from an A.C. supply through a transformer T and full wave rectifier R. A relay A in series with the supply has an armature which is normally attracted but which operates to short circuit a resistance C when the supply fails ; since the relay has to be reset by hand a heavier current is supplied when the supply is resumed. A visible disc 10 is mounted on the armature and indicates failure of supply. In a modification the contacts 11, 12 of the relay are omitted and the rate of charge can be manually adjusted by a variable resistance D when failure has been indicated by the disc 10.

Abstract: 1466326 After burners EXXON RESEARCH & ENG CO 10 April 1974 [11 April 1973] 15866/74 Heading F4B An after burner particularly for an I.C. engine, comprises a cylindrical combustion chamber with a tangential inlet or inlets for the gases to be burnt near one end, and a tangential outlet for the products of combustion near the other end. Gases from a rotary piston engine 10, Fig. 1, are fed through a pipe 12 to the after burner 13 and delivered to a silencer 15 and tail pipe 16. Air for combustion delivered by a fan 19 driven by the engine is partly fed through the hollow walls of the combustion chamber to the exhaust gas inlet 12 and partly fed direct to the inlet 12 through a valve 21. Exhaust gas from a multicylinder engine may be delivered to the after burner through a number of inlets. The planes of the axes of the inlets and outlets may be perpendicular to the axis of the after burner chamber, or may be inclined to it, and the after burner chamber may be frusto-conical, or a wider cylindrical output section may be joined to the cylindrical input section by a frusto-conical part. The combustion air pre-heated in the after burner jacket may be fed directly into the combustion chamber through an axial stub (Fig. 15) or through slots in combustion chamber lining (Figs. 17-19). An after burning engine exhaust system, Fig. 20, comprises an after burner 26 connected to the engine exhaust outlets. Air from a fan 59 driven from the engine passes through a valve 62 to eliminate fluctuations of back pressure, to an air manifold 64 feeding the after burner inlet pipes, and into a jacket 54 surrounding the combustion chamber. Excess air which does not pass direct from the jacket to the after burner space is fed to the manifold 64. A "gulp" valve 70 connected between the fan 59 and the engine air inlet manifold 57 increases the air fed to the engine when the engine inlet manifold pressure is low, e.g. when the engine is decelerating.

Title: Method for the production of p-substituted benzene sulphonamide-1,3,4-thiodiazole compounds
IPC: C07D285/135
Filed: 1942-11-11
Abstract: Para - substituted benzenesulphonamido - 1 : 3 : 4-thiodiazoles are prepared by reacting a para-substituted benzene sulphonyl halide with a thio-semicarbazone of an aliphatic aldehyde followed by oxidation. The para-substituted group on the benzene sulphonyl halide is either an acyl-amino-, nitro-, azo- or hydrazo-group. The condensation preferably takes place in a basic solvent such as pyridine.  The preferred oxidizing agent for the final step is potassium ferricyanide.  In an example, p-acetylaminobenzenesulphonyl chloride is added to a pyridine solution of acetaldehyde-thiosemicarbazone and the reaction product heated on the water bath.  The condensation product thus obtained is oxidized with potassium ferricyanide in alkaline aqueous solution to give 2 - amino - benzenesulphonamido-5-methyl-1 : 3 : 4-thiodiazole.

Abstract: A hog cholera vaccine of reduced virulence is obtained by inoculating another animal, such as a rabbit, in which the hog cholera virus will not ordinarily propagate, with a normal strain of hog cholera virus, preparing an inoculum from said other animal, e.g. from the spleen thereof, after a period of one to six days and injecting a non-immune hog therewith, allowing the virus thus transferred to propagate in the hog, preparing another inoculum from said hog and injecting the viral preparation into a second such other animal, repeating said alternate passages until the virus is so modified that it will propagate in such other animal, continuing serial passages of the modified virus through a plurality of such other animals, removing the virus and preparing a vaccine therefrom.  At least five and preferably twenty animal passages are required to produce a satisfactory virus.  If desired, one or more alternate passages through a hog may be included in the plurality of serial passages through the other animal.  In the example rabbit-hog passages are repeated until the rabbit commences to show signs of fever whereupon the virus is propagated through rabbit passages alone, the inoculum being prepared from rabbits in the febrile condition.

Abstract: 1,027,778. Transistor circuits. ELLIOTT BROS. (LONDON) Ltd. April 21, 1964 [April 23, 1963], No. 16045/63. Heading H3T. [Also in Division G4] In a circuit for converting a sinusoidal function into a linear function three-phase sinusoidal components are derived and fed to amplitude-limiting circuits, a waveform inverter being in series with one of said limiting circuits, the three outputs of the limiting circuits being summed so as to derive the required linear function. As shown in Fig. 1, a voltage at terminals 10, the magnitude of which is dependent on the sine of a function, is converted at 11 into three phase components (a, b, c, Fig. 2, not shown), each of which is clipped at half amplitude so as to provide trapezoidal waveforms (A, B, C). One of the waveforms is inverted at 15 before they are fed to a summing amplifier 16 to provide a triangular waveform (b, Fig. 5, not shown). A phase splitter 17 provides triangular waves (a, b) in opposition whilst a further circuit 19 provides a square wave (c) from the input voltage at 10. The outputs of circuits 17, 19 are fed to a circuit 18 which produces a sawtooth voltage the instantaneous value of the ramp portion of which bears a linear relationship to the required function. Fig. 6 shows a circuit suitable for use in block 18. On positive half-cycles at 33, NPN transistor T1 is conductive, cutting off diodes D4, D6 and allowing the first ramp of the waveform at 31 to be passed by diodes D3, D5 to the emitter follower T2 feeding output terminal 35. During negative half-cycles at 33, transistor T1 is non-conductive allowing diodes D4, D6 to pass the second ramp at 32 to the output terminal 35. The D.C. level at 31 is lower than that at 32 hence the two successive half-cycles at terminals 31, 32 are combined at 35 into a linear function.
