Title: Improvements in or relating to cathode ray tube oscillographs
IPC: H04N5/74
Filed: 1934-12-21
Abstract: 449,176. Television receivers. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, and YOUNG, A. J., 61, Galveston Road, Putney, both in London, and MYERS, L. M., Roseberry, Cornfield Road, Middlesbrough. Dec. 21, 1934, No. 36663. [Classes 39 (i) and 40 (iii)] A main beam of electrons is projected on the whole of an area 2 where a picture is to be reproduced, and the density of electrons in different parts of the beam is controlled by an interposed permeable electrode 3 which is scanned by a signal-controlled cathode ray to produce controlling - potentials on different elemental areas. The scanning-ray is modulated in intensity or in velocity and is projected from an electron gun 4b towards the openwork electrode 3. The main beam passes through the electrode to the fluorescent screen 2, and either the electrode or the screen acts as an anode. The screen may consist of particles of carbon which glow when heated by electronic bombardment. The electrode 3 consists of a perforated aluminium plate coated with insulating aluminium oxide, which is coated with conductive material cross-ruled to produce a mosaic of elemental conductive areas, Figs. 2 and 3 (not shown). A sufficient leakage path for the elemental condensers is obtained through the oxide. Alternatively, the electrode consists of conductive rings set in an insulating compound.

Title: Balloon limiter for twisting frames, particularly double-twist twisting frames
IPC: D01H7/88
Filed: 1964-09-09
Abstract: In Fig. 2 (not shown) a balloon limiter for a double twist device comprises a rigid outer wall 10 and a resilient inner wall 12 defining an enclosed volume 13 which can be filled with a gas or liquid at an adjustable pressure.  The pressure may be raised or lowered to change the shape of the inner wall.  The inner wall 12 may be of rubber or a plastic foam and it preferably has ribs or scales on its inner surface; the wall may be of ferous material so that the fluid in volume 13 percolates therethrough to act as lubricant. Figs. 7 and 8, (not shown), the inner wall 12 is polygonal in horizontal cross section and tapers towards the bottom: each panel of the wall may bulge inwardly at its centre. Radial walls may be formed between the inner and outer walls to form separate cells.  In a further form the inner polygonal surface of the limiter is defined by separate cells positioned edge to edge.  Instead of maintaining a constant pressure in the fluid, between the walls this pressure may be pulsated so that the walls vibrate and contact between the balloon and the limiter is intermittent.  In an alternative embodiment a cushion of e.g. foam or soft rubber is formed on the rigid outer wall and the inner wall coated with e.g.p.t.f.e or polychloro-trifluoroethylene together with e.g. polyvinyl chloride, polyamide, polyurethane, polyureas, melamines or formaldehyde resins. Fabrics, glass fibres or paper are preferably inserted as reinforcing elements.  Blind holes and grooves may be formed in the outer side of the cushioning to increase its resilience.

In the method described the casting machine is started at an optimum speed and the speed is measured since variations occur due to the rate at which molten metal is supplied to the mould, the time taken by a sector of metal to pass from its entry into the machine to its exit from each of the secondary cooling zones is determined by computer and from this time the flow-rate at which coolant is to be supplied to each secondary cooling zone is determined in order to maintain a desired temperature distribution along the strand. Values are controlled to ensure that coolant is supplied to each of the cooling zones at the rate determined for that zone.
