Title: Improvements in and relating to the manufacture of insulating material
IPC: H01B3/00
Filed: 1929-03-21
Abstract: 308,315. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts-Ges.). March 21, 1928. [Convention date]. Drawings to Specification. Insulation.-An insulating material is made by coating particles of a substance with a thin layer of a material having a lower conductivity, and uniting the particles into a coherent mass. Metals may be sprayed into an oxidizing or carbonating atmosphere to form a film of oxide or carbonate, or drying oils may be sprayed, or powdered, dried or polymerized oils may be heated in air or oxygen to form a film of oxidized oil. Particles may also be coated with a lacquer of natural or artificial resin or the like. The particles may be compacted by pressure or, in the case of metals, by spraying at high temperature and pressure. Where air gaps in the mass are a disadvantage, these may be removed by consolidating at high pressure, this being assisted by grading the particles, or by soaking in a liquid insulating material such as a solution of " bakelite. " Specifications 269,510, 269,511, and 277,289 are referred to.

Title: Process of reclaiming rubber
IPC: C08J11/16
Filed: 1942-07-03
Abstract: In reclaiming vulcanized rubber scrap, particularly scrap containing textile fabric such as used tyre covers, the scrap is cut into pieces and subjected to intense mechanical action in an internal mixer at a temperature of 180-300 DEG  C., preferably about 220 DEG  C., in the presence of sufficient oxygen to ensure softening of the scrap without substantial resinification.  Air or a compound which yields oxygen may be employed.  Preferably, the pieces of scrap are subjected to a preliminary heating to about 150-190 DEG  C.  A catalytic softening agent such as phenylhydrazine, thiophenol, aldol-a  or b -naphthylamine, mercaptobenzthiazole, xylyl- or naphthyl-b -mercaptan may be added to the material under treatment. A reducing gas, such as sulphur dioxide, or an inert gas, such as carbon dioxide or the decomposition products of ammonium carbonate, may also be introduced into the mixer.  A dry powdered filler, such as carbon black, china clay, kieselguhr, light magnesium carbonate, whiting, silica or ebonite scrap may be added, preferably shortly before or after the material has reached peak temperature.  The material is discharged from the mixer, preferably after the addition of a little water, as by spraying, in a plastic condition and, after straining, if necessary, may be immediately refined and sheeted.

Title: Improvements in or relating to electrical starting devices for internal combustion engines
IPC: F02N15/06
Filed: 1933-11-20
Abstract: 434,081. Turning-gear. DELCO-REMY CORPORATION, 329, East 1st Street, Dayton, Ohio, U.S.A.-(Assignees of Dyer, J. B.) Nov. 20, 1933, No. 9473/35. Convention date, Jan. 28,1933. Divided out of 433,937. [Class 7 (v)] [See also Group XXXV] An electrical starting device for an internalcombustion engine comprises an electromagnet 41 having two coils 48, 50 adapted to be energized under control of the engine throttle to move the armature 40 to close the starting motor switch 54, 56, 64, one coil 50 being short-circuited when the starting motor switch closes the other coil 48 then holding the switch closed until the engine' starts. The armature 40 is secured by a lost motion connection to a lever 36 co-operating with a splined sleeve 26 and an over-running clutch 28 on the shaft 24 of the starting motor 20 so that movement of the armature 40 to close the starting motor switch also brings the motor pinion 30 into mesh with the engine gear 32. Energization of the coils 48, 50 is controlled by an electromagnetic switch 91 which is energized only when the ignition switch 65 and the switch A<1> are closed. The switch A<1> which is preferably of the kind described in Specification 434,082, [Group XXXVII], is closed by movement of a member 84 connected to the engine throttle and is adapted to be opened by suction produced by running of the engine. The starting apparatus is de-energized when the engine starts either by the effect of engine suction as described above or by the de-energization of the electromagnet 91 by the counter voltage produced therein by the engine driven generator 69. The coil 50 is provided with a few turns more than the coil 48 so that opening of the motor switch is ensured when on opening of the contacts of the switch 91 a current flowing from the battery through wire 110 and coils 50 and 48 produces opposing fluxes in these coils. If the engine fails to start, opening of the starting motor switch may be effected by opening the ignition switch, free movement of the armature sufficient to allow the starting motor switch to open being permitted by the lost motion connection. The movable contact 64 of the motor switch is spring pressed on to the fixed contacts 54, 56 when the switch is closed.

Title: Improvements in or relating to pressure transducers
Inventor: PIERCE DONALD
IPC: G01L9/08
Filed: 1964-03-06
Abstract: 1,089,394. Piezo-electric pressure transducers. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 2, 1965 [March 6, 1964], No. 9652/64. Heading G1N. A transducer for measuring gas pressure nas a Piezo-electric element (10) (lead zirconate) bonded to a backing bar (11) (lead) of which the speed of sound and Young's modulus are lower. The cross-sectional areas of the element and backing are equal, at least in the region of their contiguous faces. The backing bar is embedded in a solid base (12) of a different material such as resin-bonded fibres or fabric. Compression waves are thus absorbed in the base to prevent ringing. As described, the crystal end of the base is threaded to screw into a cap (22) closing a chamber in a shock tube. This end of the base terminates flush with the free face of the crystal, an annular gap being left between it and the crystal. This gap is closed by a flexible diaphragm (16) bonded to the crystal through an intermediate metal foil (20). The diaphragm extends beyond the base to seal the cap (22) and ensure that pressure is applied to the end but not to the sides of the transducer. Electrical connection is made to the crystal through an extension (19) of the backing bar and through the body of the shock tube and the metal foil or the diaphragm. Quartz, Rochelle salt, and barium titanate are also suggested as suitable crystals.

Title: Improvements in or relating to machines for attaching heels to shoes
IPC: A43D79/00
Filed: 1938-03-31
Abstract: 513,082. Heel-attaching machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., GOULDBOURN, J., and KESTELL, T. A. March 31, 1938, No. 9810. Addition to 451,350. [Class 17 (i)] The liquid pressure piston and cylinder device described in the parent Specification is modified. The cylinder 5 carrying the last engaging plate 1 is constructed and operates as described in the prior Specification. It reciprocates relatively to an internal member 15 carried by a sleeve 11 slotted to allow liquid to pass to and from an upper enlarged part of the cylinder 5, as in the prior construction. The member 15 is bored to co-operate with a piston 17 actuated by a lever 25 as described in the parent Specification. The piston is, however, bored to guide a valve 27 urged on to its seat by a spring 33 adjustable by a hand wheel 37. At the lower end of the piston are three recesses 41 by which liquid can flow into the cyinder 5 as this descends. The valve 27 seats against the upper end of an axial passage in the piston, allowing escape of liquid when a predetermined clamping pressure is reached. To retain the liquid the upper enlarged end of the cylinder 5 has sliding engagement with a cylindrical shield 43, the space within which communicates by a tube 47 with a casing 49 having a closure 53 forming a baffle, for escaping liquid-laden air, comprising a depending rim 67, an annular groove 71 and passages 69. The air pressure may be closed by a valve 61 closed by a spring and opened by a lever 75 connected by a Bowden cable with a cam-operated lever arranged to close the valve during almost the whole power cycle, but to open it when the machine comes to starting position. The valve 27 may be locked against lift during the driving of the fasteners. The head 31 of the valve 27 is then extended as a rod 91 projecting above the handwheel 37. A latch 97 is pivoted to an arm rising and falling with the piston, and is formed with a stop 99 sliding over a fixed surface 107 and with a cam surface 121. Normally in line with the surface 107 is a block 119 on a lever urged by a spring against a fixed stop 117 set back from the surfaces 107, 119. In operation,. the latch descends with the piston until the stop 99 slips below the block 119, the latch 97 then swinging into 'line with the rod 91 to prevent this rising. When the heel has been attached, and the clamp is rising to release the work, the stop 99 raises the block 119 until the cam surface 121 moves the stop clear, the stop then sliding up the surface 107 to starting position. Specifications 23031/11, [Class 17 (i)], 451,410, 475,579 and 500,801 are referred to.

Title: Process of producing differently coloured marble, veined or streaky sponge rubber
IPC: C08L21/00
Filed: 1928-04-02
Abstract: 302,102. Gummi und Balatawerke Matador Akt.-Ges., and Girg, F. April 2, 1928. Indiarubber, colouring, ornamenting, and variegating.-Multi-coloured marbled', veined or streaked sponge rubber is formed by combining together coloured primary masses to which the gas forming and softening media suitable for the particular colours have previously been added in graded quantities. In an example, to produce a white and blue marbled or grained rubber, the white mass has 15 per cent of gas forming substances and 2 per cent of softening medium added to it, the corresponding quantities for the blue mass being 12 per cent and 5 per cent respectively. To distribute the colours, sheets of the differently coloured masses are superimposed and rolled together. The compact roll so formed is twisted and rolled into strips which are united to form a plate and vulvanized in a mould. To obtain sharper definition between the colours the primary sheets may be superficially vulcanized before they are superimposed.
