Abstract: 1,004,374. Transformers. P. GOUT. Sept. 17, 1963 [Nov. 30, 1962], No. 36447/63. Heading H1T. Two fixed electric windings a, a<SP>1</SP> (e.g. for an autotransformer) each comprising non-touching turns of a single- or multi-filament conductor, have a movable connection between them which comprises for each winding at least two mutually insulated but mechanically connected brushes b, d and b<SP>1</SP>, d<SP>1</SP>, each brush or a group of brushes associated with a winding being able to take up a position between successive turns of that winding without contacting the turns, and each brush b, d &c., being electrically connected to the corresponding brush b<SP>1</SP>, d<SP>1</SP> &c., of the other winding (this preventing circulating currents). The windings may be arranged either on the same straight axis and end to end (Fig. 5) interleaved (Fig. 10) or one inside the other (Fig. 6, not shown). Or they may be arranged, on parallel adjacent axes with or without interleaving (Fig. 7, 8), or else they may form a toroid, either in two halves (Fig. 9) or with the two windings interleaved and wound in opposite directions with successive turns of each winding on opposite halves of the same toroid, (Figs. 17, 18, not shown). The brushes may form a ring (Fig. 7) or a part of a helix (Figs. 3, 4, not shown) or may be arranged in two sets offset from one another by half a thread (Fig. 10).

Title: Improvements relating to lubricating oil cooling systems for internal combustion engines
IPC: F16N39/02
Filed: 1938-12-14
Abstract: 522,740. Lubricating systems for internal combustion engines. HURST, W. F. F. MARTIN-, and BRITISH THERMOSTAT CO., Ltd. Dec. 14, 1938, No. 36472. [Class 12 (iii] [Also in Group XIII] In a lubricating system for internal combustion engines oil is supplied to a cooling vessel b through an annular chamber o which is fitted with baffle p partially surrounding the vessel b. When the engine is cold the pressure of the oil entering the chamber o by the pipe a is sufficient to move a spring-pressed plunger i in the discharge passage m to allow the oil to pass to the outlet d without passing through the vessel b: As the oil heats up it warms the oil in the vessel b and its pressure diminishes so that the plunger i closes the passage m. The oil is then forced to pass through ports q into the vessel b to reach the outlet d. The vessel b contains a number of small air tubes c and is fitted with baffles r to cause the oil to take a tortuous path. The air entering the tubes c is regulated by shutters e operated by a link and rocking arm-mechanism f, g by the rod h of the plunger i.
Patent GB-823186-A (GB)
Title: Improvements in or relating to phosphoric and thio-phosphoric acid esters
IPC: C07F9/165
Filed: 1957-11-22
Abstract: The invention comprises compounds of the formula <FORM:0823186/IV (a)/1> in which R is a straight or branched chain C1-C6 alkyl group, an aryl- or aralkyl residue, any of which may, if desired, be substituted, or a heterocyclic group, R1 is an alkylene group, R2 is a C1-C4 alkyl group, R3 is a hydrogen atom or a C1-C3 alkyl group, R4 is a halogen atom (e.g. chlorine), a hydrogen atom, or C1-C3 alkyl group or a carbalkoxy group, R5 is a halogen atom (e.g. chlorine), a hydrogen atom or an alkyl group, X is an oxygen or sulphur atom and n is 1 or 2.  Specified R groups include ethyl, phenyl, p-chlorophenyl, p-nitrophenyl, ethyl and pyridyl.  The products may be obtained by oxidizing a compound of the formula <FORM:0823186/IV (a)/2> so as to convert the sulphur atom between the groups R and R1 to the group SO or the group SO2 without affecting the carbon-carbon double bond. Suitable oxidizing agents for this purpose are chlorine, bromine, hypochlorous or hypobromous acid or a salt thereof, or hydrogen peroxide.  The temperature is preferably maintained at -20 DEG  to +20 DEG  C. during the addition of the oxidizing agent.  The oxidation may be carried out in an aqueous medium or in an aqueous alcoholic medium or in a mixture of water and an inert organic solvent, e.g. a chlorine-containing hydrocarbon.  The amount of oxidizing agent depends on whether a sulphonyl or sulphoxyl compound is desired as product and the calculated molar amount should be used in order to avoid affecting the carbon-carbon double bond.  The products are effective as insecticides (see Group VI).  The phosphoric acid esters used as starting materials may be obtained by reacting appropriate phosphites with a -halogenated aldehydes or ketones.ALSO:A pesticidal composition in the form of a dusting powder, suspension, emulsion, solution, aerosol, ointment or bait, comprises a carrier and a compound of the formula <FORM:0823186/VI/1> in which R is a straight or branched chain alkyl group having 1 to 6 carbon atoms, an aryl- or aralkyl residue, any of which may, if desired, be substituted, or a heterocyclic group, R1 is an alkylene group, R2 is a C1-C4 alkyl group, R3 is a hydrogen atom or a C1-C3 alkyl group, R4 is a halogen atom (e.g. chlorine), a hydrogen atom, a C1-C3 alkyl group or a carbalkoxy group, R5 is a halogen atom (e.g. chlorine) or hydrogen atom or an alkyl group, X is an oxygen or sulphur atom and n is 1 or 2.  Specified R groups include phenyl, p-chlorophenyl, p-nitro-phenyl, ethyl and pyridyl.  The compounds may be used in admixture with other pest control agents.  Specified carriers include cellulose shavings and sugar.

Title: Improvements in apparatus for transmitting television
IPC: H04N3/36
Filed: 1938-12-15
Abstract: 522,545. Television. GENERAL ELECTRIC CO., Ltd., and ESPLEY, D. C. Dec. 15, 1938, Nos. 36553/38 and 29590/39. [Class 40 (iii)] In a television transmitter of the type having a Nipkow disc and an optical system for forming an image of a moving film on the disc, or of the disc on the film, inaccuracy in the interlaced scanning owing to shrinkage of the film, is corrected for by displacing the image through a small distance in its own plane during successive scans. To effect this a tilted glass plate is placed before one set of holes in Nipkow disc but not before the other. An equivalent such as a pair of oppositely directed wedges separated by a short distance may be employed. In order to correct for the difference in optical length a plate of glass of the same thickness but not tilted may be placed before the other set of holes, or an adjustably tilted plate may be placed before each set of holes. A metal plate 1 is screwed to wooden runners 2 which abut against the film and press it resiliently against the member carrying the gate by means of oval leaf springs 3 which abut against fixed members when the plate 1 is slid into position by means of a handle 4. Light from the gate passes through an aperture 5 in the plate 1. Spring arms 7 press along the sides of a glass plate 8 pressing the upper edge into notches on projections 9 and pressing the lower edge towards the plate 1. The projections 9 are situated half-way along the sides of the aperture 5 and consist of screws with half their heads filed away. The lower part of the glass plate 8 rests on a shoulder formed in a leaf spring 10, which can be adjusted by a cam 11 and screw 12 to vary the tilt of the plate 8. When used in a transmitter of the kind described in Specification 482,049 or 505,760, no separate compensating plate is required. Specifications 465,184 and 498,625 also are referred to.

Abstract: 1,143,172. Purification of nitriles. UGINE KUHLMANN. 10 Aug., 1967 [26 Aug., 1966], No. 36837/67. Heading C2C. [Also in Division C1] Epoxide compounds contained in aliphatic nitriles, produced by the ammoxidation of ethylenic hydrocarbons, are removed by converting the epoxides to glycols by hydration in the presence of an acid catalyst and the subsequent distillation of the reaction mixture to isolate the nitrile substantially free of epoxide compounds. The purification is suitably effected at 10-100‹ C. at a pH of 1-4À5 and it is preferred that a stoichiometric excess of water is present in relation to the epoxide. The catalyst may be an organic or inorganic acid, e.g. hydrochloric, sulphuric, toluene sulphonic acid, an ion exchange resin in its acid form, or a less dissociable acid such as picric, oxalic, phosphoric or acetic. In examples, HCN, acetonitrile and acrylonitrile are purified.
