Abstract: 930,205. Separating liquids. P. M. VAN DER MEER. Jan. 12, 1960 [Jan. 12, 1959], No. 1036/60. Class 46. The vessel is filled with a mixture of liquids supplied by nozzle 10 until the level reaches the opening 18. When the jet is continued the. greater part of further supply of liquid will escape via port 9 to discharge 16. However due to the shape of the collar 12 there will be a tendency for the lighter liquid in the jet to reverse direction and flow out via 16 while the heavier liquid will carry straight on into the body of the liquid. The dimension of the opening 12 is such as to allow the maximum separation; in practice twice the area of the nozzle.

Title: Improvements in or relating to rubber coated articles and method of making the same
IPC: B29C70/68
Filed: 1933-01-12
Abstract: 414,747. Indiarubber. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Chrysler Corporation; 341, Massachusetts Avenue, Highland Park, Michigan, U.S.A.) Jan. 12, 1933, No. 1098. [Class 70.] A metal wire or other article is coated with a hard rubber composition containing sulphur and rubber in a completely unvulcanized condition ; the coating is then heated for a time sufficient to vulcanize the coating partially and thereby to produce a firm bond with the metal. The coated article may then be placed in contact with a rubber or rubber-containing member and caused to adhere thereto by further vulcanization of the coating, or a number of coated articles may be assembled in predetermined contacting relation, for example to form a network, and secured together by further vulcanization. The coating may be formed in several layers ; each layer may be partially vulcanized before application of the next or the layers may be partially vulcanized as a whole. The coating may be applied by dipping or as an atomized spray from a gun; in the latter case a solvent or vehicle such as petrol is included in the composition to reduce the viscosity. The metal article may be heated before or during application of the coating to a temperature below that of vulcanization but sufficient to drive off the solvent or vehicle in the inner portion before the viscosity of the outer portion is increased sufficiently to prevent escape. A suitable hard rubber coating composition consists of 100 parts pale crepe rubber, 1 part benzothiazyl disulphide, 0À25 parts tetramethylthiuram disulphide, 10 parts zinc oxide, 20 parts lithopone, 100 parts precipitated whiting, 20 parts ferric oxide, 2 parts stearic acid and 60 parts sulphur in a volatile vehicle. Another composition consists of 100 parts rubber, 60 parts sulphur, 1 part accelerator, 10 parts zinc oxide and 100 parts pigment in a volatile vehicle. The first vulcanization should preferably be discontinued when 10 per cent of the sulphur present has combined with the rubber. A wire bead consisting of several coated strands may be incorporated in a tyre by the process. In the coating apparatus shown the wire 12 after passing through cleaning and rinsing baths is dried and heated to 180‹ F. by passage through an oven or by electric currents induced from a coil 20. It then passes to a tank 23 where it is coated with the hard rubber composition either by immersion or by spraying from an annular nozzle 24. On emergence the coating is partially vulcanized by heating to 212-325‹ F. by means of an induction coil 27. Heating of the wire may also be effected by direct connection in an electric circuit. The tank 23 is heated by a pancake induction coil 29. The wire may receive a second coating in a similar tank after which it is passed through powdered soapstone to prevent adherence of successive convolutions during winding on a spool.

Title: Improvements relating to gas turbine plants
Inventor: LLOYD PETER
IPC: F23R3/58
Filed: 1949-01-14
Abstract: 676,208. Gas turbine plant. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. March 16, 1950 [Jan. 14, 1949], No. 1142/49. Class 110(iii) In a gas turbine plant comprising a compressor driven by a gas turbine, a gas producer supplied with air by the compressor and a combustion chamber receiving combustible gas from the producer, the gas producer is of the vortex type having a tangential air inlet for setting up a radially inward vortex gas flow which leaves the producer through an axial outlet. The gas producer is shown in Fig. 1. Air, preferably preheated and mixed with steam, is led through a tangential duct 1 into a chamber 3 through which it flows radially inwards with a vortex motion before being discharged through an axial outlet 5. Liquid fuel, primarily for combustion, is injected by a nozzle 11a in the wake of a baffle 11b while fuel, e.g. pulverized coal or coke, primarily for the gas producing reaction, is injected through a nozzle 11 at the axis of the chamber. The degree of atomization or pulverization is chosen so that the equilibrium paths of the fuel particles until they are consumed are within the chamber 3 but outwardly of the outlet 5. The paths of the primary (combustion) fuel particles are preferably at a greater radius than those of the secondary (reaction) fuel particles. In the gas turbine plant, Fig. 3, the compressor 25 driven by a gas turbine 26 supplies air through an exhaust gas heat exchanger 27 to the combustion chamber 28 and through a booster pump 29 and an air heater 30 to a producer unit 31 of the type described above. The producer unit is operated above the ash fusion temperature and the slag is removed from the combustible gases in the chamber 32. The combustible gases leaving the chamber 32 pass through a steam generator 33 and, if necessary, through an auxiliary gas cleaner 34 to the combustion chamber 28. The steam generator injects steam into the producer 31 at its inlet. If the nature of the fuel permits, the chamber 32 and cleaner 34 may be dispensed with. The gas producer fuel may be led tangentially into the vortex chamber 3. According to the Provisional Specification all the fuel may be introduced at the axis of the vortex chamber. Specification 639,483 is referred to in the Complete Specification and Specification 338,108, [Class 55(ii)], in the Provisional Specification.

Title: Improvements in or relating to apparatus for facilitating the washing of glasses and other domestic hollow ware
IPC: A47L15/00
Filed: 1953-01-15
Abstract: 737,898. Washing drinking glasses etc.; rubber brushes. LINNIT, C. E., and DOWNS, B. W. Jan. 7, 1954 .[Jan. 15, 1953; Dec. 4, 1953], Nos. 1272/53 and 33859/53. Classes 19 and 138 (1). In a hollow - ware washing apparatus of the kind comprising a base having a number of upstanding brushes at least one of which can enter the article being washed while one or more of the other brushes are disposed outside the article, each brush comprises an upright element fashioned from rubber or rubber-like material and having integrally formed therewith resilient fingers which radiate in all directions therefrom along the height thereof. The apparatus, Fig. 1, comprises a resilient and substantially triangular metal base-plate 15 secured to a rubber suction pad 10. At the centre of the plate 15 is secured by a screw 22 and adhesive 23 a brush 19 comprising a wooden core 20, a ferrule 21 and a rubber sleeve 27, provided with resilient fingers 28 and secured to the core by adhesive and tacks 30. Each of the three corners 18 of the plate also mount a brush 19 differing from the centre brush only in that springs 24 are provided within the ferrules and the mounting is effected with washers 25, 26. The springs 24 permitrotation of the outer brushes to allow for wear of the fingers 28 and the resilient plate allows the outer brushes to yield laterally. The construction shown in Fig. 3 is somewhat similar except that the plate 15 is circular and six outer brushes surround a taller central brush 33. The cores 20 of at least the outer brushes do not extend the full height of the sleeves 27 and thus leave a hollow space 31 in each brush. Holes 32 in the sleeves communicate with the spaces 31 so that when the apparatus is secured by its suction pad 10 in a bowl containing washing liquid, the liquid can enter the spaces 31. During a washing operation such liquid squirts out of the holes 32. In this construction the plate 15 may be rigid and the cores mounted therein only by screws 22 and washers 25, 26, the ferrules and springs being omitted. When an article having a handle thereon is rotated on the central brush the outer brushes can be sprung apart to permit passage of the handle.
