Title: Improvements in x-ray projection apparatus
IPC: G21K1/04
Filed: 1945-02-09
Abstract: 590,580. R÷ntgen-ray apparatus. GENERAL ELECTRIC CO., Ltd., and CALDWELL, J. T. Feb. 9, 1945, No. 3314. [Class 98 (i)] In an adjustable diaphragm for limiting an X-ray beam of the kind consisting of two pairs of straight-edged leaves 18, 19, 25, 26 of a material opaque to X-rays, the two leaves of each pair being constrained to move equally and oppositely in directions perpendicular to their straight edges, the two directions being perpendicular, a single control member is provided capable of two kinds of movement, each movement controlling the opening of one pair of leaves only. As shown, the leaf 18 is operated by an arm 20 carried on a drum 15 and the leaf 19 by an arm 21 of a bell-crank operated by a lever 22 operated by another arm secured to the drum 15. The leaves 25, 26 are similarly coupled to a drum 14. A joystick 1 mounted in a ball socket joint on a column 2 carries a plate 4 to which pairs of wires 5, 6, 10, 11 are secured at opposite ends of perpendicular diameters. The wires pass through a plate 9 and are led over pulleys or through flexible casings to the drums 14, 15, the wires 5, 6 being led in opposite directions round, and secured to, the drum 14, and the wires 10, 11 being similarly secured to the drum 15. Movement of the joystick in the directions VO, VC, HO, HC opens and closes the diaphragm vertically and horizontally respectively.

Abstract: 1,060,172. Protective arrangements for battery charging systems. C.A.V. Ltd. Jan. 13, 1966 [Jan. 26, 1965], No. 3315/65. Heading H2H. [Also in Division G3] A charging system for a battery 16, of the type comprising an alternator 10, a main rectifier output 11 and an auxiliary rectifier output 14 supplying a regulator 18 and the alternator field winding 19a, is provided with a relay having two operating coils 19, 20 and two pairs of normally-open contacts 17, 21 controlled by energization of the coil 19 from the output 14. A transistor 28 is biased from the battery 16 through a resistor chain 29, 30, the arrangement being such that if the battery is incorrectly connected transistor 28 is cut-off and the coil 19 cannot be energized to close contacts 17, 21. Should the battery become open-circuited when the system is operating normally, the voltage surge occurring at terminals 12, 13 breaks down a Zener diode 23 to make conductive a normally-open controlled rectifier 22 and so permit current flow through the coil 20 between terminals 13, 15, thus limiting the magnitude of the surge. This also reduces the supply to the field winding 19a and the alternator output falls until the energization of coils 19, 20 is insufficient to hold contacts 17, 21 closed. Opening of these contacts switches off the rectifier 22 and allows the alternator output to build up again and ,reclose contacts 17, 21.

Inventor: JEFFREY GEORGE MALCOLM
IPC: D02G1/18
Filed: 1962-01-30
Abstract: Yarn possessing elastic properties e.g. recovery from a 10% extension, is produced by forming a yarn from at least two components, one thermoplastic and the other (3-15%) heat-shrinkable, heating the yarn to shrink the shrinkable component and to allow the thermoplastic component to deform, and subsequently stretching the resultant yarn to a length not greater than e.g. 90% of, its length before heating.  The components may be continuous filaments or staple fibres of a polyacrylonitrile, polyamide, polyester, polyolefin, polyvinylchloride or cellulose acetate or triacetate, which may have been previously crimped, or the shrinkable component may be a yarn thereof.  The components may be blended as fibres or in the form of slivers, spun into singles yarns and doubled with twist opposed to the singles twist.

In the apparatus shown in the Figure the reaction vessel is divided into zones by baffle plates 4 and 6 which provide orifices decreasing in diameter from the outlet to the inlet end. Molten sodium and titanium tetra- 'chloride are fed to the vessel through pipes 7 and 8 respectively, terminating in concentric nozzles, the sodium passing through the inner nozzle. Argon in introduced through pipe 9. To aid the formation of titanium aggregates titanium pellets are introduced through a screw conveyer 10. The pellets are preferably roughly spherical of diameter 1/8-3/8 inch and are used in amount 1-5 per cent of the weight of tetrachloride fed to the vessel. The vessel is preheated to reaction temperature e.g. 850C. and is rotated at a peripheral speed of 50-150 feet per minute. Reactants introduced in zone 1 spill over baffle 4 into zone 2, are lifted by elevator channel 5 into zone 3 and the products of reaction are removed from the vessel through the scoop and helical channel 12 which also provides a seal against escape of gases. At the inlet end of the vessel a seal between the rotating and stationary parts is provided by a stuffing box 13. Specification 717,930 is referred to.

In apparatus for the liquid treatment of a web in open width form, on entering and leaving the treatment bath, the web is passed over a support whilst being subjected to treating liquid sprays. In the apparatus shown, the web C passes over a feed roller 3, through a slot in the top of a substantially liquid- and steamtight tank 1, and down over a supporting plate 4, the liquid sprays being directed towards the plate in a downward slope to assist the feed of the web. A further spray is provided at the base of the plate 4 and is operated intermittently to project the web into a recess 6 so that the web falls in folds or plaits down a sloping rear wall 7 and into the treating liquid 2. A spray plate 8 is situated in the bath of treating liquid and spaced from the side walls of the tank so that treating liquid can pass from one end of the tank to the other. The web is taken up over guide rollers 12 and passes between a supporting plate 11 and associated spray means 17. The treated web leaves the tank through a water seal 13 and is squeezed in a mangle 15. Each spray means 16, 17 comprises a central header (20) fed with treating liquid by means of a pump (25) drawing liquid from the bath; branch pipes (21) extend perpendicularly from the header pipe (20) and carry further header pipes (22), Fig. 2 (not shown). Each header pipe (22) is provided with a series of nozzles (23), Fig 4 (not shown), the outer nozzles being arranged to project laterally divergent jets of liquid to prevent the edges of the web from curling inwards. A water supply 36 and a chemicals supply 39, together with a steam heater 43 may be provided in tank 1.

Title: Process and apparatus for lining metallic tubes with insulating material
Inventor: LENO JOHN ALBERT
IPC: B62K3/00
Filed: 1956-02-09
Abstract: <PICT:0793006/III/1> Metallic tubes are lined with insulating material by drawing a solution of the material, e.g. a synthetic resin such as polyethylene or polystyrene, up into the vertically disposed tube, allowing the solution to drain therefrom at a constant rate so as to leave a coating of solution on the interior surface of the tube, then heating to evaporate the solvent from the coating. If necessary in order to keep the material dissolved, the solution while being drawn up and while retained in the tube may be maintained at an elevated temperature by heaters outside the tube.  As shown, a solution of polyethylene in xylene is enclosed in a storage tank 1 heated by steam coils 2, and a copper tube 3 previously treated by vapour de-greasing, acid pickling, washing and plating with cadmium or other metal, or by cleaning which may or may not be followed by the controlled formation of an oxide film, is connected in an air-tight manner to the tank 1 by a tube 4 which dips into the solution.  An inert gas, e.g. nitrogen, under pressure is admitted to the space above the solution in the tank by pipe 11 and valve 9, and the solution is thus forced up the tube 3 until it appears in the sight-glass 7 being kept hot by the steam coils 18.  The solution is allowed to remain in the tube for a time, then drained back into the tank at a constant rate controlled by the automatic valve 8 which allows pressure to be increased at a predetermined rate to compensate for the loss of head of the solution, leaving a film on the interior surface of the tube.  The xylene is evaporated from the film by the heating coils 18, the heating is then stopped and the vapour removed by a stream of inert gas via the pipes 6 and 16.  As a further example, a solution of polystyrene in toluene may be used; in this instance, solution is effected at room temperature, the tank is not heated, and the tube 3 is only heated after the solution has been drained back into the tank.  Specification 751,322, [Group XL (b)], is refrered to.
