Title: Improvements in folding hoods for toy vehicles
IPC: A63H17/26
Filed: 1964-12-14
Abstract: 1,031,310. Toy vehicles. W. H. MULLER, [trading as SCHREYER & CO.]. Dec. 14, 1964 [Dec. 13, 1963), No. 50883/64. Heading A6S. The foldable hood of a motor driven toy vehicle is supported on hoops or stays pivoted on side posts 1d of the chassis and is actuated by the vehicle motor. In one arrangement, Fig. 1, the front stay 2 carries at one side a sector plate 3, and when the hood is to be closed a button is pushed inward and causes the surface of this plate to be frictionally engaged with a disc 4 driven by the clockwork motor 1a until the edge of the plate passes the inner end of the button. This button end then acts as a hood-retaining stop, the hood being returned to the collapsed position by a spring 20 when the button is retracted. In a modification (Fig. 2, not shown) the hood is actuated by operating push button 8 to move a slide 7 into frictional or rack-and-pinion engagement with the motor drive, the slide operating the stay 2 through a segmental lever 5 and pinion 6. In a further modification (Figs. 3 and 3a) the stay 2 is operated through a cam and bell-crank lever.

[Also in Divisions C3 and D1] The invention comprises fluorinated glycidyl ethers of the formula where R represents hydrogen or halogen or an unsubstituted or halogen-substituted aliphatio or cycloaliphatic group, at least two R's being fluorine, and R<SP>1</SP> is the same as R, or the two radicals R<SP>1</SP> are joined to form an optionally halogen-substituted alkylene chain. The glycidyl ethers are prepared by reacting a fluorocarbinolate of the formula where M is an alkali metal, with an epihalohydrin. The fluorocarbinolate reactant may be prepared by reacting a ketone of the formula with an alkali metal fluoride, preferably in a solvent for the ketone, and subsequently used in the above reaction without prior isolation. Preferred glycidyl ethers are those in which all the radicals R are fluorine. The ether may be polymerized to yield polyethers which can be used as proofing agents for fibrous materials (see Divisions C3 and D1).

Each device 9 comprises a tubular part 10 screwthreaded in a bore 11 in the socket 2 and a second part 12 secured to the ring 7 and slidable to a limited extent within the tubular part 10, flanges 12e, 10a on the two parts contacting when the tubular part 10 is unscrewed sufficiently from the socket 2 and thereby enabling the ring to be moved into the groove 6 enable telescoping of the pipes 1, 2. Locking of the pipes 1, 2 is produced by screwing the tubular part 10 inwardly until its flange 10a bears against the ring and forces it into the groove 5. The pipes 1, 2 and the ring 7 are bevelled 3, 4, 8 for ease of connection. Pins around the circumference of the spigot 1 engage recesses in the socket 2 to prevent relative rotation.

A tyre vulcanizing press includes side wall mould parts 5, 6, radially movable tread moulding segments 10, and a curing bag 17 housed within a cylinder 15 urged upwardly by a pressure cylinder 14. The bag rim is removably clamped between the overhanging edge of the cylinder 15 and an annulus which receives the lower rim of the tyre 27. The annulus is forced into engagement with the bag rim by a cylinder 21 with an appropriately shaped lower edge so that when the cylinder 21 is turned about the cylinder 15, the lower edge rides on fixed lugs 22 whereby a ring 23 is forced upwardly into engagement with the annulus. Instead of lugs 22, a ring 31, Fig. 3, is secured to the cylinder 15 and supports a ring 32 with circumferentially spaced upstanding bolts 34 which bear against a ring 35 which clamps the edge of the bag, and is attached to an annulus 19 which receives the lower rim of the tyre. By turning the ring 32 relative to the cylinder 15 the bolts are aligned with perforations 36 in the ring 35 so that when the cylinder 15 is raised the bolts slide into the perforations and the bag rim is unclamped.
Patent GB-552534-A (GB)
Abstract: 552,534. Signs or indicators. BRITISH THOMSON-HOUSTON CO., Ltd., and MAXTED R. Jan 28, 1942, No. 1175. [Class 3(ii)] A device for facilitating estimation of the distance away of an object carrying the device comprises a uniformly illuminated background 5 over which is posed an opaque figure having at least two parts of widely differing widths. The figure shown is a cross having a horizontal bar of preferably 20 to 30 times the width of the vertical bar. At the greater distances the area is seen as of uniform texture, but on approach the wider horizontal bar becomes visible, and the area appears to consist of two uniform parts, one above and one below the bar. On still closer approach the vertical bar becomes visible, and four separate areas are seen. Thus when the device is mounted on the back of a vehicle it gives the driver of another vehicle in the rear a means of estimating whether he is at a safe distance behind, when, owing to darkness, &c. the outline of the front vehicle may not be clearly visible. The background 5 may consist of a flashed opal screen behind or in front of which is a light filter, and illuminated from the rear by a lamp. A shade prevents direct light rays from reaching the screen, but the lamp is backed by a pyramidal reflector having a white band located medially in its otherwise black surface. By pre-selecting the width of this band the degree of illumination of the screen can be determined. The front of the screen is made reflecting to cause it to be distinguishable from the cross in daylight. The colour of the filter may be chosen to give a code indication of the type of vehicle carrying it, and the cross may be held in place by wing nuts 9 so as to be readily removed and changed.
