Title: Improvements in or relating to air tubes for pneumatic tyres, and the manufacture thereof
IPC: B29B15/02
Filed: 1922-08-29
Abstract: 211,902. McLeroth, T. B. Aug. 29, 1922. Extrusion machines; moulding pipes and tubes and wheel tyres.-Multicellular tubes for pneumatic tyres are obtained by extruding rubber through an annular die and forcing axially into the tube a thus formed a series of rubber discs n. Means are also provided for inserting valveless feed tubes 37 in the compartments thus formed and for sealing them to the tube by base studs. The die, Fig. 4, comprises two coaxial toroidal tubes b, c of which the outer b is the longer and is attached by a flange d to the outlet of a rubber forcing or spacing machine, and is surrounded by a steam jacket f. A plunger g is reciprocated in the inner tube by an arcuate extension of an arm 26 moved on a pivot 28 from a driving shaft t, Fig. 1, by an arm 25. The discs n are fed from a reservoir o down a tube s to a slit formed between the die and a similarly shaped bracket j, and are positioned in front of the plunger g by means of a projection 33 thereon. The plunger g is provided with perforations 32 to prevent formation of air pockets and with a recess 60 to receive the feed tubes 37, which are held in position by a spring 62. The feed tubes are contained in radial chambers provided in a disc-shaped carrier 41 mounted to rotate round the bracket j, and are fed therefrom by a plunger 47. The carrier 41 is rotated by rack- and-pawl mechanism operated from an arm 65 pivoted on a block 50 secured to the plunger 47, the plunger and carrier being actuated in unison by an arm 52. The feed tubes are fixed in the compartments on stud bases at the end of the stroke of the plunger g by a plunger 86 operating through a slit h. The stud bases are supplied from a hopper 67, Fig. 15, on a quadrant 70 which is reciprocated on a pivot 72 by an arm 82 so as to feed the studs to a recess 64. The latter is provided with a ledge 76 which is moved to one side by contact with the end of the tube c and then allows the stud to fall on the spike 102 of the plunger 86. As shown in Fig. 19, this. plunger has an adjustable head 97 and a collar 99 containing an annular die-plate 100 pressed upwards for a spring 100, and it is reciprocated by an arm 89, Fig. 4, so as to first perforate the tube a, and then penetrate the base of the feed tube 37, thus forcing the tube a over the enlargement of the feed tube 37 and securing the latter to the stud. The various parts are operated in correlation from cams 58, 95, 85, r, Fig. 1, on the driving-shaft t which through rods 55, 92, 83, x, actuate the arms 52, 89, 82, y, the arm y serving to operate the device for feeding the discs n from the reservoir o. Specifications 160,942, 189,552, [Class 144 (ii), Wheel tyres, Pneumatic &c.]; 189,821; 199,769, [Class 144 (ii), Wheel tyres, Pneumatic &c.]; and 200,132, [Class 38 (v), Electric switches &c.], are referred to.

Title: Extinguishing arcs in electrical switching devices
IPC: H01H9/44
Filed: 1973-05-17
Abstract: 1427548 Extinguishing arcs SIEMENS AG 17 May 1973 [17 May 1972] 23673/73 Heading H1N Arc runner electrodes 2, 3 in an electrical switch have first portions defining a " circulatory " (i.e. closed, e.g. annular) path that an arc will follow, under the influence of a magnetic field generated as a function of the arc current, if the arc current is sufficiently high; the electrodes also having second portions 20, Fig. 4, defining between them an additional path for the arc, the additional path leading off from the circulatory path at a transition location at which when the arc current is sufficiently low the arc will migrate from the circulatory path to move along the additional path thereby to become quenched by contact with a cooling surface provided by a solid electrically insulating body 21 of the switch. An arc formed between switching contacts 5, 6 migrates to gap a between arc runner electrodes 2, 3 assisted by blow out coils 14, 15. Electrodes 2, 3 may be identical or one may be replaced by a metal sheet (134, Fig. 15, not shown). The second portions of the electrodes may, as Fig. 1, be spaced axially or be side-byside (Figs. 5, 6, not shown). There may be a plurality of additional paths (Figs. 10-13, not shown). The arc may be caused to follow the additional path when the arc current is low and thus also the Lorenz force tending to keep the arc on the circulatory path is low, by means of either an air gap (as shown in Fig. 4), permanent magnets (Figs. 7-13, not shown) or pneumatically (not shown). So that the arc, if not extinguished on the additional path (e.g. if the instantaneous arc current increases) may return to the circulatory path, the second portions of the electrodes may reapproach the first portions at an end (as in Fig. 4) or at an intermediate point (Fig. 14, not shown) or rejoin (Figs. 7-13, not shown) the first portions. The arc runner electrodes may be in a sulphur hexafluoride quenching atmosphere. The cooling members 21 may be ceramic, e.g. aluminium oxide or mica or asbestos with a rough or porous surface. The electrode portions defining the additional path may be divergent in the direction of travel of the arc. The blow out coils may have induction rings inducing a phase shift between arc current and the magnetic field produced thereby (30, 31, Fig. 5, not shown).

Title: Improvements in or relating to rocket projectiles
Inventor: WALTERS ARTHUR GWYNFRYN
IPC: F42B10/30
Filed: 1957-07-29
Abstract: 946,700. Self-propelled missiles. MINISTER OF AVIATION. July 10, 1958 [July 29, 1957], No. 24026/57. Drawings to Specification. Heading F3A. A rocket projectile is given an axial spin for means of inclined nozzles round the projectile body. The discharge from the inclined nozzles may be derived from either an auxiliary charge or the main charge and is delayed for a short interval, following the ignition of the main charge, to prevent spinning of the projectile while on the launcher. Where an auxiliary charge is used, it is ignited either by the main charge gases or, independently, by an electric circuit. In all cases, the spin discharger exists during the early stages of the flight only. Where the auxiliary charge is ignited from the main charge a rupturable copper disc or a combustible cordite disc is inserted between the main and auxiliary charges and is destroyed at a predetermined interval after the ignition of the main charge, by the main charge gases. The auxiliary charge may be ignited electrically either directly through an external circuit or by an e.m.f. induced in coil wound round the projectile. The induced e.m.f. is generated as the projectile moves forward, initially, through an energized, fixed coil. Where the spin discharge is provided by the main charge the main charge gases operate a dash-pot type valve, the movement of which admits the main gases to the spin nozzles after a delay and isolates them after a further period.

Title: Improvements in or relating to motion transmitters
Inventor: FOSTER ALAN
IPC: H01H63/16
Filed: 1956-08-03
Abstract: 839,324. Clutches. INTERNATIONAL COMPUTERS & TABULATORS Ltd. July 1, 1957 [Aug. 3, 1956], No. 24051/56. Class 80 (2). [Also in Group XXXV] An electrostatic friction clutch adapted to effect intermittent movement of a stylus 4, Fig. 1, from a continuously-rotating shaft 11 for marking on impression-receiving material 1 comprises a cylinder 14 of a dielectric material having a constant of at least 1000, such as barium titanate, secured on the shaft 11 and a surrounding band 18 of an electrically-conductive material such as phosphor bronze. The ends of the band are anchored to an element 22 which is urged against a stop 24 by a spring 7 on the stylus 4. The surface of the cylinder 14 is polished and preferably lubricated by a pad of polytetrafluorethylene so that in the de-energized state the friction between the cylinder and the band is insufficient to move the stylus 4 against the spring 7. On the application of a D.C. voltage across an inner conductive liner 13 of the cylinder 14 and the band 18 the electrostatic action locks the band 18 to the cylinder to produce a movement of the stylus against the action of spring 7. At the end of a forward movement of the stylus the clutch is deenergized and the electric stress discharged through a resistor 26. A suitable switch may be operated for the energization and de-energization, or a pulse from a generator 8 with positive and negative-going portions may be utilized. Control by A.C. voltage will provide energization and de-energization at each halfcycle where the frequency is low but for highfrequency voltage the band stays locked to the cylinder when the voltage is applied and a switch as for D.C. voltage must be used for energization and de-energization. A positive reciprocating movement of the stylus could be obtained by utilizing an oscillating shaft 11 and maintained whilst the clutch is energized. A clutch for the transmission of continuous rotary movement is shown in Fig. 4. A disc 12 on a driving-shaft 11 engages through a dielectric disc 14 a disc 18 on a driven shaft 27 which is spring-loaded axially. Alternatively a series of separate spring-loaded pads could be arranged on one of the discs 12, 18. Specification 707,736 is referred to.

Title: Improvements in machines for applying pressure to the bottoms of shoes
IPC: A43D89/00
Filed: 1937-09-03
Abstract: 478,185. Sole - levelling machines. UNITED SHOE MACHINERY CORPORATION. Sept. 3, 1937, No. 24066. Convention date, Sept. 10, 1936. [Class 17 (i)] Relates to shoe-bottom pressing machines, especially sole-levelling machines of the kind described in Specification 236,270, [Class 17 (i)]; and consists in means for supporting the intermediate part of the last, which means engages the shoe yieldingly, is initially movable by the shoe as this is positioned, and is thrust firmly against the shoe prior to the bottom pressing operation, e.g. in response to the movement of the jack to operative position. As shown, the toe support is of the kind described in Specification 419,944, and the toe end of the shoe is pressed firmly down thereon by tip of the heel pin as described in Specification 269,114, [Class 17 (i)]. The jack is pivoted on a shaft 64 and is arranged to be swung by the operator, from jacking position, rearwardly, into position to be connected by a spring pin 68 with an arm 66 also pivoted on the shaft 64 and connected to power operated mechanism by which the jack is oscillated. The toe support carries a sleeve 44 guiding a slide 42 supporting a rubber pad 38 for engaging the wedge-shaped upper end of the instep portion of the last. The slide 42 is secured to a rod 48 over which are threaded a strong spring 58 and a weaker spring 56, separated by a plate 50 secured to the bottom of the sleeve 42. Teeth 70 on the sleeve gear with a pinion 72 rotating with a ratchet wheel 96 provided with an adjustable masking sleeve 82 and a pawl 98 guided in an arm 88 pivoted on the sleeve. The arm 88 carries a roll 112 urged toward the arm 66 by a spring. In operation, the shoe on its last is positioned on the last pin and this is tipped to force the fore part of the shoe down upon the toe pad 32. This movement depresses the instep pad 38, the rack 70 being allowed to descend because, at this time, the pawl 98 is depressed by the sleeve 82. The jack is then pushed forward, the roll 112 contacting with the arm 66 and swinging the arm 88. At a predetermined point the pawl 98 contacts with the ratchet wheel and rotates the pinion 72 giving a positive upward thrust to the instep pad. After the levelling operation, when the jack is swung rearwardly for change of work, the roll 112 leaves the arm 66 and the pawl 98 is released from the ratchet wheel.

Filed: 1966-05-31
Abstract: 1,151,873. Welding by fusion. UNION CARBIDE CORP. 31 May, 1966 [1 June, 1965], No. 24074/66. Heading B3R. [Also in Division C7] In a process for depositing metal on a workpiece, e.g. welding or cladding, a molten pool is formed on the workpiece by striking an arc between a consumable or non-consumable electrode 3 and the workpiece 5 and at least two consumable wires 9, 11 heated to an elevated temperature by current passed therethrough are fed below the surface of the pool. The current passing through and resistance heating the wires sets up interacting magnetic fields which cancel each other out or alternatively cause the arc to oscillate from side to side or where three wires are used to move in an orbital, e.g. circular path. The arc may be supplied by D.C. of either polarity or single phase A.C. 01 multiphase A.C. where a plurality of arcs are used. The electrode may be of tungsten connected to the negative pole or of water cooled copper connected to the positive pole. A transferred plasma arc may be used. The wires may be supplied in pairs with A.C. or D.C. in series or with separate D.C. or A.C. supplies or the phases of a multiphase A.C. The wires and electrode may contain flux as a coating or core, be of solid round or strip or tubular form or composed of two or more twisted wires. A shielding gas and/or flux may be used. The flux may contain alloying ingredients. It may be fed by gravity in submerged arc welding or in the shielding gas. A magnetic flux adhering to the electrode may be used. All the wires may have a common feed device. To start the process the wires may be heated by an oxy-fuel torch. Shielding gases referred to are argon, helium and carbon dioxide or mixtures thereof or with oxygen, hydrogen or nitrogen (e.g. argon and 2% oxygen). The wires may be of the same or different composition. In an example two wires and an electrode of 65% Ni, 28% Cu, 3À5% Mn, 0À95% Si, 0À05% Co, 2% Ti, balance Fe, C, S, Al, Cr were used with a transversely oscillated torch and a gas shield of 50/50 argonhelium and a trailing shield of argon to clad a low alloy Cr-Ni-Mo steel.

Title: Improvements in vacuum filters
IPC: B01D33/00
Filed: 1920-08-18
Abstract: 176,395. Mauss, W. Aug. 18, 1920. Leaf filters. - Apparatus comprising filter leaves adapted to be immersed in the liquid to be filtered and removed therefrom for cleansing has means for stopping filtration controlled by the clogging of the leaves. A series of leaves 12 is supported by a hollow shaft 9 which oscillates in bearings on a tank having a filtering- compartment 3 and a cleansing-compartment 4. Liquid to be filtered, for example sugar juice prepared as described in Specification 182,855, [Class 127, Sugar], is supplied to the compartment 3 through a valve 49 controlled by a float 54 so that the supply is gradually cut off as the leaves become clogged. When cleansing is necessary, a float 26 operates a valve 22 which controls the distribution of actuating-fluid to a motor 20. The motor oscillates the shaft 9 by means of a quadrant 19. Liquid from the interior of the leaves is drawn by a vacuum through the hollow shaft, a plug valve 34 at one end, and a flexible hose 39. Oscillation of the shaft to lift the leaves from the compartment 3 to the compartment 4 closes the valve 34 and opens a similar one at the other end of the shaft to admit steam to the interior of the leaves. Wash water is supplied to the compartment 4 through a pipe 5, and on immersion of the leaves the liquid level rises, overflow takes place to a trough 6, and a float 27 is lifted to reverse the valve 22 and the operation of the motor 20. A trip device keeps the valve 49 closed while the leaves are out of the compartment 3. The valve 4 is so constructed that suction is maintained in the leaves for a greater portion of the movement from the compartment 3 to the compartment 4 than of the reverse movement. A clock-driven drum 60 is used to record the movements of the valve 49. A glass inspection section is included in the connection between each leaf and the hollow shaft.

Title: Lubricating oils and process of preparing the same
IPC: C10G45/44
Filed: 1958-07-28
Abstract: A multi-grade lubricating oil is produced by treating a deasphalted residuum having a V.I. between 75 and 100 and a viscosity at 99 DEG C. of between 90 and 200 S.U.S. with hydrogen at a temperature between 391 DEG C. and 441 DEG C. at a pressure above 175 kgs. per sq. cm. at a space velocity between 0.4 and 1.5 v/v/hr. and in the presence of a catalyst which promotes aromatic hydrogenation and ring sciosion and subjecting the product from the hydrogen treatment to distillation to separate fractions having a viscosity index of at least 115 and within the maximum and minimum viscosity limits for a multi-grade lubricating oil, i.e. an oil which has the minimum and maximum viscosities for two or more viscosity grades of oil ordinarily used in automotive or internal combustion engines at different times of the year or at different temperatures.  The fuel is preferably obtained by vacuum distillation of a Pennsylvania, Mid-continent, West Texas, or Kuwait crude and subsequent deasphalting with a low-boiling hydrocarbon such as propane, propylene or butane, or less satisfactorily with sulphuric acid, phenol or sulphur dioxide. The catalyst employed for the hydrogenation may be a sulphide of any metal of the Group VI left hand column of the Periodic System mixed with a sulphide of an iron metal group.  Specified catalysts are molybdenum sulphide, tungsten sulphide or chromium sulphide mixed with a sulphide of iron, cobalt or nickel.  Dewaxing may be effected before or after the hydrogenation step using a solvent such as methyl ethyl ketone, toluene or propane and cooling and filtering off the wax.  Additives which may be blended with the product include Acryloid, a detergent comprising a mixture of barium thiophenate and calcium sulphonate, zinc dialkyl dithiophosphate, metal phenates, metal naphthenates, alkylated phenols and P2S5-terpene reaction products.  In a typical Example, (No. 1) an Ordovician reduced enide was deasphalted and preheated to 382 DEG C. and passed over a mixed nickel sulphide-tungsten sulphide catalyst at 393 DEG C. and 0.5 liquid hourly space velocity, using 140 standard cubic metres of hydrogen per barrel.  The product after a high pressure separation of hydrogen was topped at atmospheric pressure and fractionated to remove a gasoline and furnace oil.  The remainder was dewaxed with methyl ethyl ketone and then 10 W/20 and 20 W/30 multi-grade oils separated.
