Abstract: 1,113,068. Motor vehicles; vehicle wheels; paddle wheels; amphibious craft. A. J. M. CHADWICK. 5 July, 1965 [6 July, 1964; 26 Feb., 1965], Nos. 27755/64 and 8491/65. Headings B7A, B7C, B7H and B7V. A vehicle for travel on land and/or water has at least two driven rotary suspension members 6 arranged at transversely opposed positions on the vehicle and each comprising an outer face in the form of a spherical or otherwise convex cap 8 rotatable about its axis of symmetry and about a second axis parallel to the travel surface and perpendicular to the axis of symmetry to vary its effective traction diameter, the two members being carried by suspension members 22 depending below the vehicle frame 2 and being adjustable between a position with their faces directed inwardly of the vehicle when the members 6 are located substantially wholly within the lateral limits of the vehicle and a position with their faces directed outwardly of the vehicle and the members located substantially outside said limits. Each member is mounted on a shaft 10 driven by an hydraulic motor 12 supplied by an engine-driven pump 48 on the frame 2 and is pivotable about a pin 18 by an hydraulic ram (24) (Fig. 5, not shown) between the motor casing and a yoke 22 supporting the pin 18. The surface of the cap 8 may be provided with a tread or gripping pattern varying from the centre to the rim. The vehicle speed varies between zero and a maximum as each member is pivoted about its pin 18 and the ground contact point moves from the axis of the shaft 10 to the rim of the member. Reverse motion is obtained by pivoting the members beyond the zero position. The vehicle may be steered by driving the members on opposite sides at different speeds of rotation or by arranging their shafts 10 at different angles to provide different

Abstract: 1532602 Discharging articles from conveyers; feeding sheets LEVI STRAUSS & CO 4 July 1977 [16 July 1976] 27813/77 Headings B8A and B8R Pallets 4 carrying piles 46 of sheet material workpieces are loaded on to pallet supporters 16 which are supported on and spaced along parallel endless drive chains 10 so that the pallets are supported at vertically spaced positions. The workpieces are sequentially removed by rotating frictional members 52 from the top of the pile 46 on the uppermost pallet 4, a plunger 62 being operative to sense the height of the pile 46 on the uppermost pallet 4 and to generate a signal to drive a motor 34 connected to the chains 10 so that the latter are advanced, thereby continuously raising the pile relative to the members 52. When the pile 46 has been depleted electrodes 64 engage with a conductive strip (66) provided in the pallet 4 which generates a pallet removal control signal which causes a motor 76 to operate, the latter then driving an endless chain 70 on which protrusions 68 are mounted so that one of the protrusions 68 engages a handle 6 projecting from the pallet 4 and thereby draws the empty pallet 4 away from the chains 10, the handle 6 intially engaging a slotted channel 78 while the body of the pallet engages with a bar 80 which is driven by a chain 82 in the direction indicated so that the empty pallet finally comes to rest with its handle against a stop 102.

The upper roller 6 rotates at the same speed as the lower roller 7 and the lower roller 6 at the same speed as the upper roller 7 but at a greater speed than the other rollers. The plates 8, 9 may be formed of a number of plates secured to a cross-bar and may be adjustable as a whole or separately, and the forward edges of the plates may be corrugated or sawedged. In a modification the lower guide plate may be secured to a vertically adjustable plate and provided with a bent plate to form part of the guide for the plates and the upper plate is carried by an arm secured to a weighted lever and also provided with a bent plate to form the upper part of the guide. The cleaning and polishing rollers may be arranged horizontally or vertically, or the cleaning rollers may be arranged at an angle to the polishing-rollers.

Filed: 1948-11-06
Abstract: 657,270. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Nov. 6, 1948, No. 28877. [Class 39 (i)] In a method of securing a cap to the base of a glass envelope of an electron discharge device having a bulb of greater diameter than the base and a restricted neck portion between the bulb and the base, a metal collar is fitted around the cap and the base and pressure is thereafter applied to the collar to cause it to be folded over to secure the cap to the base, such folding causing the collar to engage the restricted neck portion of the envelope. A glass base 3 having a number of contact pins 5 sealed therethrough is fused at its periphery to the neck 1 of a cathode-ray tube having a bulb 2, and a restricted neck portion 4. The cap 6, to be secured, comprises a disc of insulating material formed with apertures through which the contact-pins project and carrying a positioning spigot 7. An aluminium collar 8 having an inturned flange 9 is fitted over the cap 6 and the base 3 until the flange 9 engages the cap, and is spaced from the base by a ring 10 of deformable material such as " Presspahn." The cap is secured in position by folding the unflanged edge of the collar 8 over the upper rim of the base 3 to engage the neck portion 4. This operation may be effected by the appliance shown, comprising a metal socket 11 having an aperture 12 to accommodate the contact pins 5 and the spigot 7. A sleeve 14 slides in an annular groove 13 in the socket 11 and has an inturned flange 15 which bears on a rubber ring 16, and an out-turned flange 17 engaged by the arms 21 of two levers 20 which are pivoted in two radial slots 18 and 19 in the socket 11. On applying pressure to the sleeve 14 by means of the levers 20, the rubber ring 16 is extruded radially inwards against the collar 8 the unflanged edge of which is folded over with substantially no risk of cracking the glass base 3 or the neck 1. The compressible material 10 inside the collar also serves to prevent the transmission of undue pressure to the glass. The appliance is preferably fitted with a cage (not shown) to position the envelope correctly and to protect the operator from the danger of a tube implosion.

Abstract: Phosphorus sulphides, e.g. the penta-, hepta- or sesqui-sulphides or specific mixtures thereof, are produced continuously or batchwise by introducing phosphorus and sulphur into a mass of molten preformed phosphorus sulphide in the proportions required to yield the desired sulphide.  The molten product may be cooled and solidified or flaked and finally <PICT:0652514/III/1> ground.  Molten sulphur, from tank 1 via motor-driven pump 5 and line 11, and molten phosphorus, from tank 21 via motor-driven pump 25 and line 21, are fed at a rate predetermined by automatic flow controls 14, 34 respectively, to reactor 13 containing a stirred molten mass of the sulphide required. The materials are maintained molten by hot water or steam jacketing on pipes and reactor 13.  The molten product is continuously withdrawn and fed to flaking rolls 51 mounted in air-tight housing 52 and maintained at a temperature below the solidification point of the sulphide. The solid product is flaked off by blades 55 and ground in, e.g. hammer mill 58.  Inert gas, e.g. carbon dioxide or nitrogen, may be continuously passed through reactor 13 at 47 to 48 and through mill 58 and housing 52 at 60 to 61.  The reaction temperature should be 286-513 DEG  C. for pentasulphide, 171-408 DEG  C. for sesquisulphide and 305-523 DEG  C. for heptasulphide.
