Abstract: 426,901. Moulding and vulcanizing tyres. WOODCOCK, W. J., and JOHN BULL RUBBER CO., Ltd., Evington Valley Mills, Leicester. March 17, 1934, No. 8443. [Classes 70 and 87 (ii)] In the moulding and vulcanizing of tyres, the mould halves or a fluid-operated diaphragm act to deform solid rubber cores to press the tyre band into contact with the walls of the mould. As shown in Fig. 1, the mould halves 3, 5 form part of the heated platens of a press, and the tyre 16 with the inserted core 14 is mounted upon a ring-shaped member 8. When the lower platen is raised to close the press, wedge-shaped surfaces 6 on the member 5 co-operate with similar surfaces 7 on the member 8, and other wedge-shaped surfaces 12 on the member 8 co-operate with surfaces 13 on the member 3. As a result of this action, the inclined inner surfaces 15 of the core are forced outwards, thus expanding the main section of the core. Fig. 3 shows a fluid - operated diaphragm 17, located in a recess in the ring 8 which can be inflated to either deform the core 14 or assist in deforming it.

Abstract: 417,052. Television. MARTIN, L. C., 99, Nightingale Lane, Bromley, Kent. March 21, 1933, No. 8543. Drawings to Specification. [Class 40 (iii).] Slowly moving objects are scanned at an abnormally low frame-frequency and each of the reproduced pictures is projected for a correspondingly long time. Thus a Nipkow disc at the transmitter may complete only four frames instead of the usual sixteen per second ; and the number of scanning-lines can be proportionately increased, or the speed of the scanning-spot reduced. At the receiver the picture is reproduced, by means of a Kerr-cell light-valve and a mirror drum, on a kinematograph film which is projected in such a manner that each constituent picture is exhibited for four times as long as usual ; alternatively the film may comprise four successive copies of each picture or frame and be operated at the usual speed. If the light-valve comprises a doubleimage prism in combination with a Kerr cell, one moving light-spot may be projected on to the film and the other, for monitoring purposes, on to a screen surfaced with phosphorescent material such as a Lenard phosphor; and in order that the moving spot may itself be invisible, it may consist of ultra-violet light, or light of a colour complementary to that of the screen. The light-valve may be adjusted to give a positive or negative picture or (if a double-image prism is employed) both.
