Title: Wheel assembly for a vehicle moving through a tubular conduit
IPC: B61B13/10
Filed: 1975-09-08
Abstract: 1467207 Wheel arrangements; tunnel systems TUBEXPRESS SYSTEMS Inc 8 Sept 1975 [18 Sept 1974] 36926/75 Heading B7L A wheel assembly for supporting an end of a vehicle moving through a tubular conduit, propelled by air pressure for example, comprises an axle 18 for connection to the vehicle end to extend co-axially with the longitudinal axis of the vehicle; struts 24a, 24b and 24c extending radially outwardly from a hub 20 rotatable on the axle 18; a respective wheel supporting bracket 26a, 26b and 26c pivotally supported intermediate its ends from each strut by a pivot 28a, 28b and 28c having an axis parallel to the axle 18; and a respective wheel 30a, 30b, 30c, 30d, 30e and 30f on each bracket end. As shown, the struts are equally spaced 120 degrees apart and the six wheels are equally spaced 60 degrees apart. The pivotal mounting of the brackets on the struts ensures that each wheel of the pair supported by a particular bracket will be equally loaded. Each strut 24a, 24b and 24c is telescopic and has shock absorbing means incorporated therein. Each wheel is mounted on a shaft (38), Fig. 4 (not shown), which is pivotally attached to its associated bracket, further shock-absorbing means being interposed between the shaft and bracket.

Title: Improvements in or relating to knitting machines
IPC: D04B15/00
Filed: 1964-09-09
Abstract: 1,074,748. Knitting-machines. SCOTT & WILLIAMS Inc. Sept. 9, 1964 [Sept. 9, 1963], No. 36986/64. Heading D1C. The turned welt diol of a single cylinder knitting-machine is driven at a higher speed than the cylinder during splicing of a reinforcing yarn. The yarn extends between a toothed ring secured to the diol, and the needles, and thus the trailing end of the yarn is presented to a knife at a nearly vertical angle and cut close to the fabric. A shaft 36 driven at the same speed as the needle cylinder selectively rotates either of the wheels 44, 46 of a composite gear 48, via a dog 40 keyed to the shaft. The gears mesh with the wheels 70, 68 of a composite gear 64 connected by a suitable gear train to the dial drive shaft. The wheels 44, 46 have a different number of teeth so that normally when the dog engages the former the diol is driven at the same speed as the cylinder; when the wheels 44, 46 are lowered the dog engages the latter and the diol rotates faster than the cylinder.

Title: Improvements relating to the bonding of thermoplastic materials
Inventor: OSBORNE ALAN PAUL
IPC: C08J7/02
Filed: 1959-10-30
Abstract: The surface of a solid thermoplastic synthetic polymer, e.g. in the form of a sheet or film is modified, by treating it with a liquid which is capable of dissolving the polymer at an elevated temperature, by maintaining the liquid at a temperature at which it is a solvent for the polymer but below the melting point of the polymer for an interval of time such that if the polymer surface were free from the solvent, the surface would have a matt white appearance, and cooling the polymer surface while still wet with liquid to a temperature at which the liquid is no longer a solvent for the polymer, and if desired, removing the solvent from the polymer.  The polymer may be polyethylene, polypropylene, polybutylenes, a copolymer of ethylene and propylene, a vinyl chloride polymer, a polycarbonate, or a polyether obtained from a halogenated pentaerythritol.  The treating liquid may be xylene, white spirit, naphtha, kerosene, pinene, turpentine, cyclohexanone, or chlorobenzene.  The surface treatment of the following polymers are exemplified, polypropylene, a polycarbonate resin, a polyether, a blend of polyvinyl chloride and chlorinated polyethylene, and polyethylene.  In the examples are included synthetic rubber compositions for making sheets for laminating to the treated polymer sheets.  Amongst these compositions are (1) a resin-rubber shoe sole composition consisting of a 75/25% styrene/butadiene resin, natural rubber, a 75/25% butadiene/styrene rubber, zinc oxide, calcium silicate, stearic acid, coumarone resin, paraffin wax, sulphur, pigments, and vulcanizing agents, and (2) a butyl rubber composition consisting of butyl rubber, chlorosulphonated polyethylene, whiting, china clay, mineral oil and vulcanizing agents.

Abstract: 1,042,179. Television; cathode-ray tube accessories. COMPAGNIE FRANCAISE THOMSON-HOUSTON. Sept. 20, 1963 [Sept. 21, 1962], No. 37102/63. Headings H4F and H4T. [Also in Division G6] A television camera tube, particularly for use in an atomic reactor, is cooled by the expansion of a liquid coolant contained in a double-walled housing surrounding the tube. In one embodiment, Fig. 1, the camera tube 1 together with its associated amplifier 2, lens 8 and a connection assembly 3 are contained in a metal tube 22 sealed at one end by a connector 4 and at the other end by a quartz plate 9. The tube is provided with interlocking means including a screw 17 for retaining it inside a double walled housing 13 (into which it may be readily inserted) the space 12 between the walls being evacuated and the interior 11 containing the liquid coolant introduced by means of a valve 16 and which on expansion escapes through a valve 15. When the camera is employed for examining the interior of gascooled atomic reactors the liquid coolant used is preferably of the same nature, CO 2  being utilized in the present invention. In the case of examining a (vertical) fuel element sheath, such as 19, the assembly of camera tube &c. and cooling housing is lowered into the sheath under its own weight by means of the electrical connection cable 5, stainless steel guide springs 7 (or rollers) being provided to allow of accurate focusing over the entire length of the sheath. To enable the camera to " view " the side wall of the sheath the latter is illuminated by lamps 10 and image light is directed into the camera by means of a conical reflector 6. In a second embodiment (Fig. 2, not shown) in which the sheath is also illuminated by lamps 10 image light is directed into the camera by means of a 45 degrees mirror 6 which may be rotated about the camera tube axis by means of a turbine 23 driven by the reactor coolant gas, the mirror being stopped in a desired position by means of an electromagnetic brake 25. For focusing purposes a pinion 29 driven by a step-by-step motor and meshing with a gear 35 rotates lens 8 and this rotation is converted into an up-down translatory motion by means of a pin 34 engaging a curved groove 33 in the lens housing. In this embodiment the cooling housing is provided with an annular space 30 in which the coolant fluid (liquid CO 2 ) expands and evaporates the fluid entering via a tube 31 and emerging via a tube 32 which communicates with the outside through a valve such as 15 (Fig. 1).

The brakeactuating rods are attached to the levers at points in the medial vertical plane of the vehicle, and the pedal applies force in the longitudinal direction of the underframe. In the construction shown the lever 1 floats and provides for compensation between the front and rear brakes. In an alternative construction, however, lever 1 is also pivoted to the cross-member 7. A hand lever 23 is connected with the free end of lever 2, and applies the rear brakes only owing to a lost-motion connection between lever 2 and the link 3.
