Title: Arrangement for the crystallisation, cooling and drying of fluid or paste-like material, particularly soaps, in a vacuum
IPC: B01D3/10
Filed: 1956-10-23
Abstract: <PICT:0799927/III/1> <PICT:0799927/III/2> Apparatus for the drying, cooling and crystallization of paste-like material, especially soap, in a vacuum comprises a container 1 within which a planetary roller 3 travels over the inner surface of a cylinder 2 and spreads the paste as a thin film on the cylinder and the roller.  The roller is mounted in bearing arms carried by a shaft 4, which is driven from outside the container, so that the roller revolves around the shaft.  A drive 7, taken from the shaft, causes the roller to turn about its own axis 5.  Shaft 4 is hollow and serves, together with distributer 8, which is constructed with double walls so that it may be filled with hot or cold media according to requirements.  Also, the hollow shaft 4 can be adapted for the conveyance of heating or cooling medium to roller 3.  The liquid evaporates from the paste, and the vapours leave the container through suction pipe 10.  The dried material is shaved off the roller and the cylinder by knives 9, and is withdrawn through outlet 11, which may be mounted on an extrusion press.  In an alternative embodiment, the cylinder 2 is formed by the wall of the vacuum container itself.

Title: Improvements in fluorescent screens
IPC: H01J29/28
Filed: 1948-12-15
Abstract: 677,888. Luminescent materials. BRITISH THOMSON-HOUSTON CO., Ltd., WELLS, R. S., and WARD, H. F. Oct. 20, 1949 [Dec. 15, 1948], No. 32452/48. Class 39 (i). A fluorescent material for the screen of a cathode-ray tube comprises a zinc sulphide or zinc-cadmium sulphide phosphor in which there is incorporated a soluble compound of barium, strontium, magnesium, or calcium. The compound may be the hydroxide, chloride, nitrate, oxide, silicate or carbonate and the quantity is 0.4-2 per cent by weight of the phosphor. One method of forming the fluorescent material comprises adding the phosphor to a solution of silicon ester in alcohol or methylated spirits, which is then agitated. A saturated solution of the compound is then added and the solution is again agitated. Water is added, followed by further agitation, filtration and finally drying of the powder. This treatment is stated to increase the " sticking " voltage to an extent depending upon the amount of compound added. Specification 601,593 is referred to.

Abstract: 1,269,828. Dressing grinding wheels. H. F. SWENSON. 27 June, 1969, No. 32609/69. Heading B3D. In a wheel dresser the tool, e.g. a diamond 59, Fig. 1, is supported on a pedestal 58 carried by a swivel plate 47 supported for rotation on a vertical shaft 48, Fig. 2, and the extent of rotation of the plate 47 is limited by a stop 90 carried thereby engaging with stops 40, 41,. Fig. 1, carried by a pair of nested swivel rings 38, 39. The rings 38, 39 can be rotated to predetermined positions and locked in such positions by a screw 56, Fig. 2 and the ring 39 is braked against free rotation by a spring-loaded ball 43. In one embodiment the tool 59 is mounted in a vertically adjustable block 85 on a portion 65 of the pedestal. The portion 65 is pivotable about the axis of a shaft 68 relative to the rest of the pedestal under control of a cranked shaft 77 and is spring urged to its neutral position. It includes a vibration damping resiliently mounted weight 60, and between it and a cam surface of the main part of the pedestal are balls 80 which allow compensating movement of the tool to occur as the portion 65 pivots. The plate 47 rotates on balls 46 provided in a recess in a centre member 34 surrounded by the rings 38, 39. The plate 47 carries a vernier scale and the screw 56 is carried in a vernier block 54 to ensure accurate positioning of the plate. The centre member 34, block 54 and a dresser base 32 are carried by a plate 22 slidable on rotation of a knob 33 within dovetail grooves in a base 20, and fixable relative to the base by screws 25, Fig. 1, acting against a movable plate 24. Depending on the location of the stops 40, 41 the dresser may be used to produce a convex, concave, single angle or double angle contour or a combination of such contours on a grinding wheel.  In a second embodiment the balls 46 are carried in a cage plate located between the plate 47 and centre member 34, and the carrier for the tool 59 is secured directly on the pivoted portion 65 by set screws.

Straw is cut between co-operating lines of knives 9 and 10 on rotated drums 4 and 5, the drive for the knives 10 allowing of a slight advance so that when the edge of 9 first engages with the curved projection 11 of the knives 10 it can slide along the projection until it makes a scissors-like cut with the edge of the knives 10. The pulley 8 drives directly the shaft 2 and the drum 4 and its knives 9. The gear wheel 6 is loose on the shaft 2 and carries a projecting screwed nut 13 containing a set screw 14 which abuts against a stop 15 in the wheel 8. By screwing in the screw 14 when the mechanism is stationary the gear wheel 6 is rotated slightly clockwise whereby the gear 7 is adjusted anti-clockwise thus giving an advance upwards to the knives 10 so that, on rotation, the knives 9 contact the curve 11 above the line of centres of the drums. The cutting edge 10a of the knives 10 is not a straight line but is as in Fig. 2. The straw is forced between the drums by fingers 16 on the drum 4.

[Also in Group XXIII] Malleable composite stock comprising a layer of ceramic material bonded to a layer of metal is made by rolling or squeezing the ceramic material and a malleable layer of metal together with a sufficient reduction. Reduction will be at least 50% and up to 90%, but in most cases 80-85% will give a bond so that the composite stock can be severely mechanically worked. In a continuous process, ceramic material 2 in powder form is laid from a hopper 1 on a layer of metal 3 and the whole squeezed between rolls 4. The ceramic material may be sprayed on to the metal in a slurry which is then dried before passing between rolls. Small pieces of plate glass may be used. For low melting enamels, the composite stock may be additionally heated to fuse the enamel, or further layers of enamel may be added and fused. A number of examples of ceramic materials are given and of metals, silver, aluminium and alloys of iron, nickel, copper, manganese being specified.

Abstract: 650,217. Vibration dampers. GLOSTER AIRCRAFT CO., Ltd., and EVANS, G. D. Dec. 23, 1948, No. 33145. [Class 108(iii)] [Also in Group XL(c)] An anti-vibration mounting comprises a suspension bar of resilient material adapted to be anchored at one end and pivotally connected at its other end to spring means yieldable in a direction longitudinally of the suspension bar and adapted to be connected to the equipment to be mounted. In the arrangement shown, a flexible bar 1 of rectangular cross-section secured at one end 1a within one end of a cylinder 2 which is anchored to a supporting member, is pivotally connected at its other end to a forked end 6a, of a plunger 6 which is slidable within a cylinder 11 secured at its closed end to a support member. Relative movement of the plunger 6 and cylinder 11 in either direction is resiliently opposed by a compression spring 8 located on the plunger between a pair of loose collars 7, 7. The travel of the collars is limited by a shoulder 11a within the cylinder and by a cap 14a, respectively. According to the Provisional Specification, the open end of the cylinder is fitted with a bush secured by an off-set split pin, which engages a flat on the plunger and prevents rotation of the latter relative to the cylinder. A flexible bush 5 resiliently limits deflection of the bar 1 within the cylinder 2. The connection between the bar 5 and plunger 6 may be a ball and socket or other universal joint. In a modification, the fixed end of the bar may be tapered and extend through a tapered end of the cylinder 2 for connection to the supporting member. The mountings may be used to mount a radio set in an aircraft (see Group XL(c)) and to attach an instrument panel to the cockpit of an aeroplane.
