In a p.c.m. t.d.m. receiver in which successive blocks of seven bits, separated by sync bits, are staticized SKA and immediately transferred to a buffer store SKB under the control of the sync bits, locally generated " transfer pulses, of the same frequency as the sync bits, are used to transfer the contents of the buffer store to a main store (not shown), and to avoid errors due to phase drift in the transmission line, the phase of the transfer pulses is periodically changed, when necessary, by four bit periods (four being chosen so as to minimize the number of changes necessary), this being achieved by using, for the transfer pulse the pulse from either position 1 or position 5 of an eight-stage counter RN driven by a local oscillator KL.

Title: Process for the production of pure zirconium tetrachloride and hafnium/zirconium tetrachloride by sublimation
IPC: C01G25/04
Filed: 1959-07-17
Abstract: Pure zirconium tetrachloride or zirconium-hafnium tetrachloride is otbained by subliming impure zirconium tetrachloride or zirconium-hafnium tetrachloride in an atmosphere which contains hydrocarbons with a boiling point below 150 DEG C., other than methane.  Suitable hydrocarbons include propylene, propane, butylene, ethane, ethylene, isobutane, and petroleum ether.  The hydrocarbon may be mixed with an inert gas, such as illuminating gas, nitrogen, or hydrogen.  Improved removal of aluminium impurity may be achieved by the presence of cracking catalysts, for example a silica or alumina-silica of high surface area, and/or by the presence of steam. The sublimation may be carried out in a stream of the hydrocarbon-containing atmosphere, and at least part of the gases after the removal of the pure zirconium tetrachloride or zirconium-hafnium tetrachloride may be recycled to the sublimation step.

Abstract: 1340556 Pressure diecasting machines BUEHLER AG Gebr 19 April 1971 [20 March 1970] 25067/71 Heading B3F [Also in Division B5] Apparatus for closing and locking the moulds of an injection moulding or diecasting machine comprises a stationary mould part carrier 2, a support 3 having a displacement device 69 secured thereon, at least two guideways 10, 11, 12 and 13 extending from the carrier 2 to the support 3, a mould part carrier 4 movable by the displacement device 69 along said guideways and adapted to be made fast thereon, hydraulic means acting by way of the guideways on the mould part carriers, two guide spars 40, 41 extending parallel to the displacement device 69 through the support 3 and connected with the movable mould carrier 4, and stops 76, 77 and 50 on the guide spars and displacement device respectively and arranged to limit the movement of said spars relative to the displacement device. The displacement device 69 consists of a piston and cylinder unit whose piston rod 72 is connected to a yoke 55 which is secured to the guide spars 40 and 41. The guideways 10, 11, 12 and 13 are provided with screw threads 20 and terminate in a threaded bolt 23 to which is attached a piston 25 movable in a bore 30 in the mould carrier 2. The movable mould carrier 4 may be made fast to the guideways by means of divided nuts 95, 96 located on the carrier 4 and designed to co-operate with the screw threads on the guideways, the two halves of each nut being movable towards and away from each other by piston and cylinder units 100, Fig. 2. In operation, the valve 125 is reversed so as to allow a pressure medium to pass to the cylinder 70 of the displacement device 69. This causes movement of the mould carrier 4 towards the mould carrier 2 until the stop 50 on the guide spars contacts the stop 77, the relative positions of said stops having been adjusted so that the mould halves are just in contact at this point. A valve 135 is then actuated to cause the pressure medium to be supplied to the cylinders 100 so as to move the halves of the divided nuts 95, 96 together and thus lock the carrier 4 in position on the guideways 10, 11, 12 and 13. A closing pressure is then applied to the mould halves by supplying a highpressure medium via a pipe 170 to act on the pistons 25 in the bores 30 of the fixed carrier plate 2. After opening the mould, an ejector plate 64 is actuated by supplying pressure medium to a cylinder 66. The pistons 25 may be provided with external toothing 111 cooperating with a pinion 110 mounted in a hood 32 attached to the mould carrier 2. By rotating the pinion 110 the piston may be unscrewed from the threaded bolt 23. The guideway 11 may now be withdrawn from the fixed mould carrier 2 by releasing nuts 15<SP>1</SP> and 16<SP>1</SP>, fastening the guideway 11 to the movable carrier 4 by, e.g. a strap, and moving the carrier 4 to the left using the displacement device 69. This permits the introduction and removal of bulky mould parts to and from the carriers 4 and 2.

The ink is delivered to the distributing- roller through a of feeding openings or nozzles provided in a sectional rail and means is provided for adjusting simultaneously the position of a number of the openings relatively to the distributing-roller, independently of the other openings, for the purpose of regulating the thickness of the ink film supplied to the distributing-roller. In the example thirty-two conduits 9, Fig. 2, are provided for conveying the ink through nozzles 13 to the distributing-roller 7, from whence it is carried to the thirty-two columns on the forme.
