A tyre is positioned in a diaphragm press by actuating a pneumatic piston 33 to expand the segments 26 of a chuck and cause the bead edges 45 to grip the upper bead of the tyre. The tyre is lowered by a hoist 43 over the extended diaphragm 20 until it rests on the lower bead ring 16 in the lower mould half 17. The upper bead ring 18 and the plate 22 are then lowered, and fluid under pressure supplied to the diaphragm.

Title: Improvements in explosive devices for generating linear detonation fronts
IPC: F42B1/00
Filed: 1959-04-17
Abstract: 863,194. Explosive devices. DU PONT DE NEMOURS & CO., E. I. April 17, 1959 [June 3, 1958], No. 13194/59. Class 9(1). An explosive device for generating linear detonation wave fronts, as in Specification 878/196, comprises ari inert barrier separating a pair of sets of spaced explosive trains, the sets being arranged in parallel planes and the trains of one set being inclined to the trains of the second set, so that a grid pattern is formed by the two sets. The barrier is of such a thickness that small delays are produced in the passage of the detonation wave from one set of trains to the other, thus compensating for any shortening of the path of the wave from an initiation point to a point on the boundary line produced by such "short cuts". In an example, a device to produce a square detonation front, Fig. 2, was made by using a 6 inch square brass plate engraved with parallel diagonal grooves to produce similar grooves in lead foil squares 0À005 inch thick. PETN slurry containing gum arabic was poured over the foils 2, Fig. 5, and wiped clear of the lands between the grooves. After drying the explosive, the foils were united by adhesive coated inert material 4. An electric blasting cap was placed at the centre P o , Fig. 2, to produce simultaneous detonation at points on the periphery. To obtain triangular devices, the square may be cut diagonally into four. The grooves may be spirally formed in circular discs, one or more initiators being placed at points on the circumference to produce a circular wave front travelling towards the centre. RDX, HMX, tetryl, lead azide and nitroglycerine may be used instead of PETN. Instead of lead foil, materials such as paper, polyethylene, polyvinyl chloride, cloth; felt or cork may be used. The explosive may also be applied directly to the opposite surfaces of an adhesive coated cardboard barrier. Specifications 564,211, 618,617 and U.S.A. Specification 2,774,306 are referred to.

[Class 40 (iii)] Signals from a main transmitter are received at a local transmitter and the synchronizing impulses separated and utilized to synchronize a television camera whose signals are transmitted to the main transmitter for broadcasting. The synchronizing signals H1 ... H5, Fig. 1, originally transmitted, arrive at the local transmitter with a delay a, Fig. 2. They are further delayed by a period b, Fig. 3, so that the local transmitter radiates a signal as shown in Fig. 4 and the delay produced in transmission to the main transmitter results in the signal of Fig. 5 reaching the main transmitter. The period a+b+a (i.e. the overall delay) should equal one or more whole line periods. The framing impulses V, Fig. 1, are not subjected to the delay b; the main transmitter is so arranged as not to radiate the picture signal following H"3, Fig. 3. The delay b may be produced by applying the impulses to a sawtooth generator arranged to give an impulse only when the saw-tooth has reached a predetermined amplitude ; alternatively, a multivibrator may be used, the impulses H<1>1 ... being applied to one discharge path and the impulses H<11>1 ... occurring on the anode of the other discharge path.
