Title: Improvements in hoists for gun mountings and analogous purposes
IPC: F41A9/21
Filed: 1946-08-19
Abstract: 615,043. Ammunition hoists. VICKERSARMSTRONGS, Ltd., and BRERETON, C. F. Aug. 19, 1946, No. 24631. [Class 92 (i)] [Also in Group XXX] Relates to the hoisting of materials from a fixed position to another position adjustable about the hoist and is particularly applicable to the supply of ammunition from a magazine to a rotatable turret. According to the invention, a round 39 is fed from a trough 40 through a loading aperture in the hoist casing 1 into a cage 3 which is then raised and aligned automatically with a receiving trough 38 carried by the gun turret which rotates independently of the hoist casing. In the form shown, a hydraulic machine C mounted on the floor of the turret comprises two opposed coaxial pairs of cylinders 14, 16 and 15, 17, the upper pair having a larger bore than the lower. On the floor of the magazine is carried a machine B having two single opposed coaxial cylinders 23 and 24, the bores of which are smaller than cylinders 14 and 15, but larger than cylinders 16 and 17. Lifting power is supplied by a hydraulic machine A, the whole being controlled by a valve 35. The lower cylinders of machine C and the cylinders of machine B are supplied with fluid at the same pressure, but preferably from separate supplies to avoid the use of flexible connections, while the upper cylinders of machine C and the lifting machine A may be connected either to supply and exhaust by the valve 35. To raise the ammunition, this valve 35 is positioned to supply pressure to the cylinder of machine A and the upper cylinders of machine C through holes in the fixed pistons 141 and 15<SP>1</SP>. The pairs of cylinders, 14, 16 and 15, 17 attempt to come together and to rotate the casing 1 by means of a depending lug 18 on a rack geared to the hoist casing by gears 20 and 21. One pair of these cylinders will bear against a fixed lug 22 on the base, but the other pair will exert sufficient force to rotate the casing against the action of the cylinders 23 and 24 in the magazine which will be separated. At the same time, pressure admitted to the cylinder 34 of machine A will force down the piston 34<SP>1</SP> thereby hoisting the cage by means of the cable 4 and pulleys 42 and 43. The cage will then be aligned with the receiving tray 38. Lowering is effected by putting the valve 35 to exhaust when the motion of the cage and hoist will be controlled by the machine B.

Title: Improvements in and relating to the manufacture of glass tubing
IPC: C03B23/047
Filed: 1948-09-23
Abstract: 640,878. Glass tubing. FLOOD. H. G. Sept. 23, 1948, No. 24914. [Class 56] Glass tubing having a bore or predetermined shape and dimension is made from tubing 1 having an internal circumference not greater than that required on the finished tube by causing a mandrel 2 of the required shape and size to travel through the tubing under the action of a constant or substantial constant driving force, e.g. by weight loading 6, the tubing being heated, 7, at or near the zone of engagement with the mandrel so that the heated zone travels along the tubing as the mandrel progresses; the mandrel itself tapering towards its leading edge to a size smaller than the original bore of the tubing. The mandrel and tubing may be rotated. The tubing may be heated directly or indirectly by heating the mandrel or a surrounding metal tube by H.F. induction, the heating being such that the trailing edge of the mandrel remains relatively cool. With electric resistance heating, the heating coil may be wound to give the desired temperature gradient in the tube over the length of the mandrel. The weight loading may be applied to either the mandrel or the tubing and conveniently the other is held against longitudinal movement. The tube 1 may have a portion 3 large enough to accommodate the mandrel. Some elongation of the tube 1 is produced but need not exceed 20 per cent, but if a thin walled tube is required additional localized heating is applied.midway along the mandrel and elongation of the order of 600 per cent may be obtained. Fig. 3 illustrates the shaping of the tubing as it is manufactured. The tubing is produced by overflow from a central aperture in a rotatting dish 9 with a weir 10, and after it is formed but while sufficiently soft to be shaped the tubing passes over the mandrel 3 which is arranged at the desired distance and supported by wire 4 from a chuck 5 which is rotated with or by the dish 9. The mandrel is preferably made of hard finegrain graphite.

Title: Improvements in or relating to lard shortening products
Inventor: WAL ROBERT JOHN VANDER
IPC: C11C3/10
Filed: 1954-08-30
Abstract: A shortening product comprises a blend of natural lard and lard which has been modified by treatment in the liquid phase with a catalyst to cause molecular rearrangement of the lard.  The modified lard may be made by heating lard in the presence of an alkali metal alcoholate at a temperature between the point at which the lard is in liquid phase and 150 DEG C.  Sodium methoxide and ethoxide are specified, suitably in a proportion up to 1 per cent by weight and preferably 0.5 per cent.  The catalyst may be removed by adding water and removing the products of hydrolysis by filtering or centrifuging.  The lard and the re-arranged lard may be simply mixed together or lard may be rearranged under such conditions that only part of it undergoes re-arrangement.  The mixtures may contain 5 to 95 per cent by weight of natural lard, the optimum proportions varying according to the sources of the natural lard and re-arranged lard.  In general best results are obtained by using a blend containing equal proportions by weight of lard and re-arranged lard.  Specification 710,001 is referred to.

Title: A magnetic grid for controlling a charged particle discharge
IPC: H01J17/04
Filed: 1958-08-07
Abstract: 889,198. Discharge tubes. UNITED STATES ATOMIC ENERGY COMMISSION. Aug. 7, 1958 [Sept. 5, 1957], No. 25331/58. Class 39(1) A planar control grid has adjacent sections extending in substantially opposite directions, and has a current passing through it, the resultant magnetic field being utilized as a deflecting means for controlling the passage of charged particles. In Fig. 1 the grid is shown as a double spiral 11. Thus the current in any two adjacent conductors (e.g. 13 and 16) will be flowing in opposite directions, and therefore the resultant magnetic fields between them will be additive (Fig. 2, not shown). The control exercised by such a grid would be independent of whether the stream of charged particles were positive or negative, and thus is of useful application in such gas-filled tubes as thyratrons or ignitrons to provide continuous grid control after the initiation of the discharge. The magnitude of the current can be controlled, as for example by a variable rheostat 23. In Fig. 3 (not shown), the grid is of zig-zag shape. Specification 816,351 is referred to.

[Also in Group XVIII] A reciprocating or continuously rotating motor having a permanently magnetized moving member, is energized by electrical impulses fed to a sustaining coil from a battery-fed junction transistor controlled by a potential applied from a coil situated near the magnet. As shown, Fig. 1, for a clock pendulum M having a permanent magnet arm A and magnetic flux return path F, the sustaining coil BE is fed with impulses from a transistor ATr fed by a battery G and controlled by a potential from a pick-up coil BC. A further coil BS may be used to feed further synchronous devices, e.g. further clocks. The invention is also shown as applied to a pair of magnetized balance wheels on the same spindle and having a pick-up coil between them. A modification is described in which a single balance wheel is embraced by a pair of coils BE and BC respectively. The magnetic rotor A in Fig. 4 is similarly maintained in continuous rotation by periodic energization of coil BC under the control of pick-up coil BE, the transistor acting in this case as an electronic commutator. This motor may be used to drive an escapement mechanism directly or through a slipping clutch, or for winding a mainspring through gearing.
