Patent GB-1246488-A (GB)
Title: Vapour cooling of heated bodies such as electron tubes
Inventor: LOO COENRAAD VAN
IPC: F22B1/16
Filed: 1968-08-30
Abstract: 1,246,488. Cooling electron tubes or nuclear fuel elements. VARIAN ASSOCIATES. 30 Aug., 1968 [15 Sept., 1967; 21 May, 1968], No. 41615/68. Heading F4U. [Also in Division H1] The external anode of an electron tube, for example, is cooled by an arrangement comprising a fibrous layer in contact with the anode surface to be cooled wherein the fibrous layer has a structure defining capillaries by means of which, when the anode is immersed in the liquid of a vapour cooling system, liquid is drawn to the anode surface by capillary action for vaporization and also defining larger passages allowing the substantially unobstructed passage of vapour from the anode surface. The fibrous layer material preferably is of lesser thermal conductivity than the anode, and may comprise glass fibres, steel wool, copper wool or stainless steel fibres or mixtures thereof. The fibrous layer may comprise a woven or knitted fabric and the fabric may be formed by a single web or a yarn of wound fibre. When the surface to be cooled is metallic the fibrous layer is preferably of metallic fibres, e.g. a copper anode has a fibrous layer of stainless steel, which has a positive EMF potential of less than 2À2 volts with respect to the anode to prevent electrolytic erosion thereof. Fig. 3 shows a glass fibre layer 64 with punctured holes 66 therein to allow the escape of the vapour bubbles. To ensure a good fitting of the fibrous layer to a contoured surface a frame, e.g. a wire harness, may be used. In Fig. 1 (not shown) an electron tube is mounted in the boiler of a liquid circulating closed-cycle cooling system which has an arrangement for accurately maintaining an adequate level of liquid in the boiler. Such an arrangement is unnecessary if the layer of fibrous material extends completely over the surface to be cooled since capillary action will ensure the presence of liquid over all the fibrous layer/surface interface. The fibrous material may also be organic material, e.g. cotton cloth.

Abstract: 1,203,214. Stacking-apparatus. TIMBER RESEARCH & DEVELOPMENT ASSOCIATION. 19 Sept., 1967 [19 Sept., 1966], No. 41758/66. Heading B8C. Apparatus for forming and fair-ending a stack of timber boards comprises a conveyer, a receiver on to which the boards fall, and a roller device which adjusts the boards in a lengthwise direction as they fall from the conveyer. As shown in Fig. 1, boards are moved transversely along a conveyer having dogged chains 1. At the end of the conveyer, the boards slide down guides 3, one end striking a driven roller 5 which moves each board lengthwise by means of ribs 6. The boards are subsequently moved more slowly by driven transfer rollers 7, 8 arid finally fall on to a base as described in Specification 1,117,291. Hence, one end of each board in the stack formed lies directly below the roller 8. After a time, the roller 8 may be moved away by an arm 11 so that succeeding boards are aligned beneath the roller 7 and a stepped stack is formed, Fig. 4 (not shown).

Title: Improvements in or relating to indicating devices
IPC: G01N11/00
Filed: 1962-11-07
Abstract: An indicating device comprises a capillary material impregnated with one or more reagents, sealed between two films of synthetic resin at least one of which is transparent, the device having or being adapted in use to have, at least one edge of the capillary material free of synthetic resin.  In a specific embodiment the device is made completely sealed by resin or as a continuous strip, the device being prepared for use by cutting to the required size and exposing the capillary material.  The device may have an aperture for venting either at the same or the opposite end to the free capillary edge. Two strips of capillary material may be incorporated side by side but spaced apart by a plastics film.  The capillary material may be paper, cellulosic, acrylic, synthetic or glass fibres or particulate material, cellular materials are also suitable.  The synthetic film may be polyethylene, polypropylene, PVC, polyvinyl acetate, polyvinylidene chloride but a composite sheet of polyterephthalate and polyethylene is preferred.  Pressure-sensitive adhesives may be used to join the capillary material and the film.  If paperboard is used then it is given a plastics coating to render it impervious. The reagents may be fixed or movably disposed in the capillary material.  Various applications of the indicator device are given, amongst which are (a) determination of solute:solvent ratio in a solution according to rate of travel of both components in the capillary material, a material impregnated with methyl red or pehnolphthalein being used for acid or alkali concentrations or impregnated with AgNO3 and dichlorofluoescein to determine salt concentration (b) determination of acid strength using ion-exchange paper impregnated with an indicator (c) measurement of water vapour in air by using a material impregnated with a hydroscopic material e.g. LiCl or CaCl2 and Karl Fischer Reagent wherein a predetermined volume of air is drawn up through the capillary material (d) analysis of freshness of milk using paper impregnated with methyl red and an ion-exchange resin.

Abstract: 1381382 Injection moulding KRAUSS. MAFFEI AG 14 Sept 1972 [15 Sept 1971 26 Aug 1972] 42722/72 Heading B5A An injection moulding distributer nozzle 49, 50 which extends to a plurality of moulds 5, 6 arranged in line with their planes of separation mutually parallel, comprises a first channel 46 and side channels 45 of equal length which lead to each mould and are joined to the first channel by connecting channels 47 having axes lying in a common plane perpendicular to the axis of the first channel. Portion 49 of the nozzle contains cartridge heaters 51 and portion 50 contains a high thermal conductivity metal insert 55 forming parallel side channels 45. Holes 42, 43 communicate with channels 40, 41 in space bushes 17-20 which are slidably mounted in central bores of the mould halves. When the moulds are closed conical surfaces 56, 57 of the nozzle are urged into contact with complementary surfaces 58, 59 of the spine bushes by hydraulic pressure acting on the injection cylinder. The force on the spine bush 20 is resisted by engagement with an abutment 60 after initial compression of spring 65. The abutment comprises a piston 60 sliding in a cylinder 63 fixed in mould clamping plate 4 and connected by passages 70-72 to another cylinder 74 where a regulator piston 75 is urged by a set screw 85 on the complementary clamping plate 3 to pressurize the fluid in the passageways. When the mould is opened spring 81 urges piston 75 to the right to reduce the pressure on abutment piston 61 and to align passage 82 in piston 75 with passage 73 from reservoir 88 to replenish the passages 70-72. During mould opening the distributer nozzle moves distance 89 further into the mould assembly, i.e. until abutments 90, 91 engage, and the pressure on conical surfaces 56, 59 is relieved since space bushes 17-20 are permitted greater travel 29-32 by their rollers 21-24.

Title: Treatment of sea water
IPC: C01D3/06
Filed: 1959-12-22
Abstract: Carbon dioxide and bicarbonate ions are removed from sea water by adding calcium hydroxide, for example as an aqueous solution, in at least the stoichiometric amount, stirring the resultant mixture, and immediately passing it through a sand layer, preferably having a depth <PICT:0887752/III/1> of 5-7 metres, at such a rate that the sand particles are fluidized, so that calcium carbonate crystallizes out on the surface of the sand particles.  Suitable sands include silica, river sand, sea sand, crusher-run stone, limestone powder and crushed dolomite.  The particles preferably have a size of 10-40 mesh (Tyler).  The amount of calcium hydroxide added is preferably such as to give a pH of 10,0-10.3 to the mixture.  The liquid issuing from the sand may be passed through a zone maintained under vacuum in order to remove any residual dissolved gases.  The magnesium content of the sea water remains in solution, from which it may be recovered as magnesium hydroxide for the production of magnesia clinker.  It is preferred that the mixture of sea water and calcium hydroxide remains in contact with the sand for 5 to 20 minutes.  In Figure 1, sea water from tank 1 and calcium hydroxide from tank 3 are mixed by pump 2 and passed upwardly through the sand layer 5.  The issuing solution is passed through the vacuum tower 7 to remove dissolved nitrogen and oxygen.
