Abstract: 1,066,904. Blasting. TILGHMAN WHEELABRATOR Ltd. Feb. 24, 1966 [March 1, 1965], No.8615/65. Heading B3D. Metal articles are blasted, e.g. to produce a fine or semi-polished finish, by a stream of abrasive metallic powder having a maximum particle size of less than 84 B.S. mesh and a minimum particle size of 200 B.S. mesh. Suitable metal powders include iron, steel, stainless steel, brass, copper, zinc and aluminium. The blast may be produced by an impellor wheel or by air. The powder is preferably of the same material as the metal article being treated so as to avoid contamination of the article with foreign material, this being important when treating containers for food or drink, e.g. stainless steel beer barrels. By varying the shape, hardness and composition of the particles various shades of the colour of the metal article can be produced; stencils may be used to produce a decorative effect. A base material may be plated with one or more metal coatings which are at least partially cut through by blasting to expose the colour of the coatings in a pattern.

In use, see Fig. 4, the tool 7 may be mounted on a shaft 14 having a frame 15 which may be secured to an arm 9 integral with shaft 6. To fit a tyre to a wheel clamped on the apparatus, the tool 7 is positioned so that the guide and removal elements 18, 20 abut against the radially outer surface of the uppermost rim flange 22. The tyre is then placed on the wheel so that its lower bead is partly over the rim and partly in contact with element 17. On rotation of the tool, the lower bead passes over the rim into the well 23 of the wheel. The upper bead is then placed partly over the rim and the operation is repeated. Alternatively, both beads of the tyre may be placed partly over the rim and the tool operated in the manner described. To remove the tyre from the wheel, a tyre lever is placed under the upper bead to lift it on to surface 21 of the tool. Rotation of the tool about the wheel then causes element 20 to lift the bead out of the wheel well. The lower bead may then be removed in a similar manner. In a modified construction, surface 21, see Fig. 1, may be provided with a protuberance opposite removal element 20. To remove a tyre from a wheel part of the bead is lifted over this protuberance by a tyre lever, which is retained there during the subsequent part of the removal operation. In an alternative type of fitting and removal apparatus, Fig. 5 (not shown), the wheel is rotatably mounted upon a chuck and the tyre fitting and removal tool is held stationary.

Abstract: 1,102,569. Speed governors; clocks and watches. HARVEY ALUMINIUM Inc. March 2, 1965 [March 30, 1964], No. 8951/65. Headings G3B and G3T. The angular velocity in a device 12 comprising a first rotatable mass M is kept constant by coupling it, through a cyclically varying velocity ratio transmission such as the meshing eccentric gears 10, 11 and a torsionally resilient coupling D, with a second rotating mass M2. As the resonant frequency of the system is approached, by excitation through the transmission, a resultant power loss sets up a velocity control barrier causing the regulation. The invention is applicable especially to time measuring mechanisms, in which the device 12 includes a spring driving motor. A smooth output motion over small time increments is obtained, as contrasted with escapement controlled mechanisms. Also, the mechanism is unaffected in spin stabilized environments such as in ordnance projectiles. Fig. 18 illustrates the run-down 22 of the spring motor in a non-elastic system, compared with the regulation 20 in the system described using a relatively light aluminium mass M2, and 21 using a heavier steel mass M2.
