Title: Machine for tightening the nipples of wire-spoked wheels
IPC: B60B31/02
Filed: 1958-02-12
Abstract: 852,047. Screwing-up nuts &c. CANADA CYCLE & MOTOR CO. Ltd. Feb. 12,1958 [Dec. 2, 1957], No. 4540/58. Class 83 (3). A machine for tightening the nipples of wire-spoked wheels has a base 20, a frame 22 thereon supporting a wheel-holder 24, a number of rotatable nipple-tightening heads 26, each mounted on a tubular member 28 pivotably attached to the base 20, and a central shaft 37 movable axially relatively to the base which moves members 28 radially to move heads 26 to and from the nipples. The shaft 37 is stepped to accommodate spools 48, 62, on screw-threaded portions 46, 60, respectively, the spools being connected by bell-cranks 86 to spring-biased telescopic links 98 pivoted to the members 28, so that axial movement of the shaft 37, by a piston 35 of an hydraulic cylinder 34 mounted centrally on the base 20, causes the heads 26 yieldingly to engage their respective nipples. The shaft 37 is slidably mounted in a bore 68 of an extension 70 of a crosshead 33 carried by the frame 22, and is supported in a recess 38 of a disc 36, connected to the piston 35. The disc 36, and an upper disc 58 supported by a shoulder 56 of the shaft 37, are keyed to adjacent spools by dowels, to prevent relative rotation thereof. Each disc has extensions 84 pivotally supporting the bell-cranks 86, whose arms 90, 92 engage the spools and the telescopic links 98 respectively, the latter being pivotablyconnected at 95 to the members 28, the outermembers 28 being actuated by the spool 48 and the inner members 28 by the spool 62. Upward movement of the piston causes the heads 26 to engage the nipples, and downward movement releases the heads, the latter movement being limited by a bar 42 supported from the disc 36 by bolts 40. Radial adjustment of the heads, to accommodate a different size of wheel, is by a shaft 75, mounted on a plate 77 attached to the extension 70 and carrying a gear 76 for engagement with a gear 74 on the shaft 37. The gears are held apart by a spring 78, on the shaft 75, urging against the plate 77 and a pin 80 integral with the shaft 75. On adjusting, the shaft 75 is engaged at 82 by a spanner, axial pressure is applied to compress the spring 78 and engage the gears 76, 74, and the shaft 37 is rotated to impart axial movement to the nut-like spools. Quick adjustment is facilitated by a setting-plate, representing a wheel size, inserted between the spool 48 and the disc 58, and adaptors 100 are positioned between the smaller-size wheels and the wheel support 24. Specifications 836,276 and 852,046 are referred to.

Title: An improved process for the methylation of aromatic hydrocarbons
IPC: C07C2/86
Filed: 1942-04-08
Abstract: Aromatic hydrocarbons are methylated by heating in the vapour phase at atmospheric pressure with methyl alcohol, or a compound such as dimethyl ether which yields the alcohol, in the presence of an acidic catalyst comprising a siliceous carrier material and an oxy-acid of phosphorus.  Examples are given of the preparation of toluene by passing a vaporized mixture of benzene and methyl alcohol or dimethyl ether over a catalyst prepared by mixing diatomaceous earth with pyrophosphoric acid, drying and granulating; the yield of toluene may be increased by recycling the higher boiling fraction of the product. The volume ratio of benzene to methyl alcohol is preferably 2 : 1 and higher, whilst the preferred temperature range is 325-425 DEG  C. Reference is made to other catalysts prepared by the treatment, with ortho- or pyro-phosphoric acid, of other siliceous material such as kieselguhr, silica gel, artificial aluminium silicates, fuller's earth, bentonite, montmorillonite and the material known under the Registered Trade Mark "Floridin."  To replace the phosphoric acid vaporized from the catalyst during the reaction, fresh phosphoric acid or compounds decomposing to phosphoric acid may p  be added to the feed.  Specification 541,534 is referred to.  The Specification as open to inspection under Sect. 91 also described the use as catalysts of siliceous carrier material activated by treatment with other strong mineral acids such as sulphuric and hydrofluoric acids, in which case the reaction may be conducted under pressure and in the liquid phase.  Gaseous catalysts such as boron fluoride, and liquid catalysts such as boron-fluoride-water, may be introduced with the feed.  A further example is given, describing the use of an activated clay.  The replacement of the methyl alcohol by a mixture of carbon monoxide or dioxide and hydrogen is also described; the catalyst used is then a mixture of the above catalysts with such catalysts for the synthesis of methyl alcohol as the oxides of copper, zinc, chromium, manganese and aluminium, and the process is effected at pressures up to 50-200 atmospheres.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to over-run brakes for trailing vehicles
Inventor: TOOGOOD JEFFREY
IPC: B60T7/20
Filed: 1954-02-17
Abstract: 758,389. Dashpots. TOOGOOD, M. C. Feb. 17, 1955 [Feb. 17, 1954], No. 4620/54. Class 108 (3). [Also in Group XXXIV] In a damping device for use in tractor-trailer vehicles to provide rapid application and delayed release of the brakes of the trailing vehicle, the device consists of a hollow rod 8 provided with an integral piston 15 which operates within cylinder 7. In operation, when piston-rod 8 moves in the brake applying direction 13, fluid is displaced from end 22 of the cylinder bore through port 17, chamber 16, port 19, valve means 21 in removable plug element 18 to the end 23 of the cylinder bore. Baffle means may be provided in reservoir 24 to restrict return of fluid to the reservoir during this movement. When tension is applied to the towing connection the pistonrod 8 tends to move in the brake releasing direction 14; however, this movement is resisted by the closure of the valve means 21 and the restriction 20 in plug element 18. Thus a prolonged pull by the towing vehicle is required to release the brakes of the trailing vehicle. The restriction 20 in the plug member 18 may be adjustable or the plug element interchangeable to vary the restrictor size to suit the weight of the vehicle. A modification is described wherein a U-sectioned piston seal similar to ring 28 affords the valve member 21, the seal collapsing and allowing fluid to flow over it from the end 22 to the end 23 of the cylinder.

Title: Improvements in radial piston pumps or motors
IPC: F04B49/24
Filed: 1966-02-03
Abstract: 1,141,261. Hydraulic reciprocating motors and pumps. OLEODINAMICA RUHRITAL S. p. A. Feb. 3, 1966 [Feb. 5, 1965], No.4758/66. Heading F1A. A multi-cylinder pump or motor comprises cylinders 16 disposed in a stator 43 with their axes arranged tangentially to a circle centred on drive shaft axis 11 and of a radius less than, e.g. half, the eccentricity of eccentric 10, which is engaged by piston slippers 19 with recesses 22 connected to the corresponding cylinders. The cylinders are secured in the stator by threaded members 47 carrying inlet valves 50. Discharge takes place through valves 54. In the pump embodiment shown, selected cylinders may be de-activated by by-passing their delivery to the stator interior, when predetermined delivery pressures are exceeded. By-passing of the cylinders is effected by respective valves 64 each biased by a spring 68, 69 of a predetermined load associated with the predetermined delivery pressures and actuated by the delivery pressure in outlet 62 acting on a piston 67. Valve 64 incorporates a damping device 65. A pressure relief valve, Fig. 2 (not shown), connects the stator interior to a tank in which the pump is mounted. The inclination of the cylinders to the shaft axis is such that the angle between the pistons and their slippers is less driving their working strokes than driving their return strokes, to reduce side thrusts on the cylinders. The piston 17 may be of a material of high coefficient of thermal expansion, e. g. aluminium with anodically oxidized surfaces, so that as the working fluid viscosity decreases with increasing temperature, the piston expands so as to be a closer fit in its cylinder. Sealing between components may be effected by rings 53, 59, with sharp edges which cut into the surfaces they engage.

Filed: 1962-02-12
Abstract: <PICT:0976102/C6-C7/1> <PICT:0976102/C6-C7/2> A magnetic information storage device comprises two magnetic film cores deposited in sequence on a substrate, the cores having different coercivities.  A barrier layer, which may be of silicon monoxide, silicon dioxide, magnesium fluoride, aluminium oxide, magnesium oxide and synthetic resins, prevents interdiffusion of the two cores.  The arrangement may be used as a non-destructive store in which the second deposited core, having the lower coercivity, is read destructively and the information is subsequently rewritten in the second core by the remanent magnetization of the first deposited core.  The device may be manufactured using crucibles 4, 5, 6, Fig. 3 in a bell-jar evaluated to 10-4 to 10-6 mm. Hg., each crucible having an electric heater and shutters 18, 19, 20.  The substrate 12 has a heater 7 and is covered by a mask 14. A magnetic field is applied during the deposition process by a permanent- or electro-magnet 8, which may be rotated if desired so that the easy axes of the two cores are not parallel. The temperature of the substrate may be measured by a thermocouple. The Specification discloses suitable compositions for the cores and barrier layer, and discusses the properties and dimensions required and methods of determining the thickness of the layers.  The substrate mentioned is glass although amorphous oxides such as silicon monoxide, alumina and ceramic compounds may be used. The magnetic film material is iron-nickel alloy, e.g. Permalloy 75-85% Ni, preferably 83% Ni, 17% Fe, or cobalt-iron alloy.
