Title: Separation of substances from liquid carriers
IPC: H02N3/00
Filed: 1967-11-14
Abstract: 1,212,784. Evaporation; desalination of water. GOURDINE SYSTEMS Inc. 14 Nov., 1967 [15 Nov., 1965], No. 29051/68. Divided out of 1,212,539. Heading B1B. A substance is separated from a solution or suspension in a volatile liquid, e.g. salt is removed from saline water, by converting the saline water into particulate form, heating the particles to form water-vapour with salt particles in suspension, and passing the suspension through an electric field which imparts electric charges to the salt particles which are subsequently precipitated from the stream of vapour. A stream of salt water is raised to the critical pressure by pump 200 and passed through heat-exchanger 202 wherein the salt water is preheated before entering atomizer 203. The aerosol, formed in the atomizer, flows through superheater 205 wherein the temperature is raised above the critical temperature, water is vaporized, and a suspension of brine droplets and crystalline salt particles in watervapour is produced. The suspension flows via a convergent nozzle into precipitator 206 which is provided with ionizing electrodes and, downstream thereof, an annular collector electrode. The brine droplets and crystalline salt particles are precipitated on the inner surface of the collector, and form concentrated brine solution which is discharged from the precipitator. High-pressure water-vapour leaves the precipitator through line F and flows through heatexchanger 202 wherein the water-vapour is condensed. The pressurised fresh water is utilized to drive turbine 208 which in turn drives pump .200. Fresh water, at low temperature and pressure, flows out of the turbine through line H. The process may be employed to produce solid particles of required size. The solid is dissolved in a solvent; and the solution is then atomized and heated, the size of the product particles being controlled by the concentration of the solution and/or by the degree of atomization and/or by the proportion of solvent that is evaporated.

Title: Thermoplastic shotgun cartridges and method of closure therefor
IPC: G06K11/04
Filed: 1957-09-16
Abstract: 816,544. Shot-gun cartridges. OLIN MATHIESON CHEMICAL CORPORATION. Sept. 16, 1957 [Oct. 5, 1956], No. 29136/57. Class 9(1) A shot-gun cartridge case 10 moulded from a thermo-plastic composition consisting of ethyl cellulose, butyl stearate, wax and pigment is closed by folding in the mouth of the case to form pleats, heating the folded margin to soften the plastic, forcing the pleats inwardly and upwardly and then depressing the innermost portion of the pleats to form a fluid-tight closure. The tubular wall 14 and head 16 are moulded in one piece, an axial opening 17 being provided for a primer (not shown). After inserting the propellant 13 over powder wads 12 and shot 11, the cartridge is placed in a press 19, Fig. 3, and a tool 22 attached to a ram 24 is reciprocated. The tool 22 has eight radial blades 27 having inwardly tapered knife edges 28 which depress spaced portions of the case margin to form pleats 31, between which are curved portions 32. A second tool having a bell-shaped recess is then used to force the pleats nearer together, further closure being produced by a third tool 37 equipped with heating means such as a coil 38. The tool 37 has a bell-shaped cavity in which is a projection 39, which -as the tool is lowered over the cartridge depresses the centre portion of the pleats. Finally a tool 41 is used to complete the closure. This tool comprises a pin 42 slidable in a sleeve 43 on which a bushing 44 can slide. A transverse pin 51 fixed in the sleeve rides in slots in the pin 42 and bushing 44. By adjusting a set screw 47, the compression of a spring 46 bearing on the pin can be varied; while the bushing 44 is thrust downwardly by a spring 48 adjusted by a stop 49. On reciprocation of the ram 24, thrust is transmitted to the died 53 held in the bushing by a set screw 54 to mould the top of the case 10. The tool moves downwardly until the resistance of the case overcomes the spring 48 and brings the die to rest. Continued downward motion of the ram thrusts the pin 42 downwards to depress the pleats at the centre until the resistance of spring 46 is overcome and the pin 42 is brought to rest.

Title: Improvements in disc brakes
Inventor: BUTLER HENRY JAMES
IPC: B61H5/00
Filed: 1959-08-29
Abstract: 952,612. Disc brakes. DUNLOP RUBBER CO. Ltd. Aug. 16, 1960 [Aug. 29, 1959], No. 29570/59. Headings F2E and F2F. Disc brakes have a pair of pressure-plates 12 each carrying a friction pad 13 and mounted for pivotal movement about a first centre and a second centre, so that upon application of the brakes the pressure-plates 12 are moved about their first centre to close the pads 13 on to the disc 10 and then abut their second centre to complete engagement, the mechanism providing for progressive adjustment for wear. The pressure-plates 12 are pivoted by pins 33 to toggle links 30 pivoted on a pin 31 movable in slots 32 in upper and lower plates 23, 24 and extending through a push-rod connecting a pilot piston in cylinder 29 with a spring-loaded plunger in a casing 26. The pressure-plates are suspended by front and rear supports 15, 16, the former having a universal joint at the bottom which includes the pivot 17. Pressure fluid is forced from a master cylinder to the pilot cylinder 29 so that its piston moves back to straighten the toggling 30 and part the pressure-plate ends with the result that the plates pivot about the pivot 17 to engage the pads 13 with the disc 10. Rearward movement of the pilot piston unmasks an opening 37 through which fluid passes along a pipe 38 to a main cylinder 40 pivoted to one pressure plate, its piston 42 being connected by a rod 43 to the other pressure plate, so that the plates pivot about their pins 33 to engage the pads 13 firmly with the disc 10. When the brake pressure is released, the piston 42 moves sufficiently to disengage the pads and the movement is completed by rotation about pivot 17, consequently pivots 17 approach each other as wear of the pad occurs.

Abstract: 652,022. Casting processes ; moulds ; mould materials. SWIFT LEVICK & SONS, Ltd., and HORSBURGH, G. D. L. Nov. 18, 1948, No. 29960. [Class 83 (i)] A method of casting a permanent magnet comprises pouring an alloy of the aluminiumnickel-iron or aluminium-nickel-cobalt-iron type with or without copper or other alloying constituent, from a recess 5 through gates 4 into cavities 3 in a mould 1 heated prior to or simultaneously with the pouring to delay the cooling via the sides of the mould cavities and chilling the cavities at one end by means of a chill plate 2, which may be solid or watercooled., to induce the formation of columnar crystals in a direction normal to that end, the alloy being poured at a temperature of at least 1500‹ C. to maintain the castings fluid until columnar crystals have grown substantially throughout the entire length of each casting. In one method, the alloy is raised to a temperature, e.g. of 1600‹ C. and upwards, substantially in excess of the normal pouring temperature, and the mould may be heated to a temperature in the range 600‹ to 1200‹ C. In another method, the pouring of the alloy is carried out at the usual temperature, i.e. about 1500 C. the alloy containing a metallic element, e.g. niobium, tantalum, molybdenum, titanium, tungsten, or vanadium or a combination of elements to retard the rate of setting. The mould may be made of or lined with insulating or refractory material or be of metal, e.g. steel or cast iron, suitably lined. Further, the mould may comprise a heated top part with holes forming gates leading to the mould cavities which is placed on a heated mould of a thickness equal to the length required for the cavities. In another construction, the same molten metal as is to form the castings is used to heat the mould to lessen the rate of transverse heat loss.

Abstract: 847,214. Nuclear fuel elements. PARSONS & CO. Ltd., C. A. Oct. 19, 1956 [Oct. 25, 1955; Nov. 16, 1955; March 26, 1956; April 11, 1956], Nos. 30488/55, 32819/55, 9429/56 and 11077/56. Class 39(4). [Also in Group XIII] Heat transfer between a cylindrical surface and a fluid flowing thereover through a passage formed between said surface and a further cylindrical surface, and through flow channels defined by fins on said surface and extending at an angle to the general direction of fluid flow through the passage, is assisted by baffle means which cause the fluid to be deflected out of these channels disposed beyond the first mentioned channels in the general direction of fluid flow. The invention is said to be applicable to heat exchangers generally but is described particularly in its application to a fuel container element disposed in a bore formed in the moderating material of a nuclear reactor. Fig. 1 shows a form of fuel element in which the flow channels are formed by helical fins 2 extending from the fuel container 1, these channels being interrupted by axially extending baffles 3. Cooling fluid flowing in the individual channels is deflected by the baffles 3 and the surface of the bore in which the element is housed, out of these channels and into further channels upstream of the first channels the general flow pattern of the cooling fluid between any two adjacent baffles 3 being helical. The fins 2 may be corrugated. Fig. 3 shows an alternative form in which the helical motion of the cooling fluid is effected by suitably corrugating or alternatively (not shown) by providing auxiliary fins on the axially extending baffles 12, the helical fins being omitted. The baffles 12 may extend helically. The fins 12 may be formed in pairs from sheet material bent to U-shape each limb of the U section forming one of the fins. The fluid deflecting members 2, 3, 12 may be made of graphite and may be arranged either on the fuel container 1 (as shown) or on the surface of the moderating material.
