Patent GB-691707-A (GB)
Title: Method of waterproofing hollow articles
IPC: A63B31/00
Filed: 1951-03-06
Abstract: The inner walls of hollow articles made of fabric material are coated by partly filling the article with an aqueous rubber dispersion, inflating the article, distributing the dispersion over the inner walls of the article, releasing some of the air and injecting a coagulating gas such as carbon dioxide under pressure, and finally heating or vulcanizing the article while maintaining the gas under pressure.  The articles to be coated may be water-containers, floats, inflatable mattresses, water toys, and balloons made by sewing together suitably shaped pieces of fabric. The dispersion, which may be prevulcanized, is distributed over the inner walls of the article by turning it, and a greater thickness of coating may be provided at places by holding the article in a fixed position.  Before pouring in the rubber dispersion, the outer walls of the article may be moistened with water or a solution of glue or water glass in order to contract the interstices of the fabric.

In the forn shown, the walls 54 are assembled in four groups and pipes 56, 57 and a fan 58 are provided for circulating the heating gases which are supplied by a burner at 60. Waste gases, corresponding in quantity to the fresh gas supplied by the burner, escape at 61, and a distributer 62 is fitted in the central gas channel 51. As shown in Fig. 4, horizontal movement, by means of a screw 84 and a hand wheel, of some or all of the walls 54 in each group is permitted by the provision of resilient connecting plates 87, distance bolts 88 and angle members 89 limiting the movement in both directions. The heating walls are formed with vertical baffles 75 and gas-tight joints at the upper and lower ends of each group are obtained by water seals 66, 73. The latter comprises a trough and a co-operating flange on a frame 71 which is secured to the walls 54 and is pressed against the base plate 72 by springs 91. Instead of employing a fan, circulation of the heating gases may be effected by the kinetic energy of the fresh gas introduced; in both cases alternately operated valves are provided for periodically reversing the direction of flow of the gases.

Title: Electronic storage device
IPC: H01J29/44
Filed: 1960-02-25
Abstract: 874,288. Cathode-ray storage tubes. HUGHES AIRCRAFT CO. Feb. 25, 1960 [Feb. 26, 1959], No. 6715/60. Class 39(1). The target of a storage tube has a conducting layer covered at least in part by a layer of insulating material having throughout a common range of electron energy level both a secondary electron emission ratio greater than unity and an electron bombardment induced conductivity whereby electrons of a predetermined energy level charge the target by means of secondary emission and discharge the target by bombardment induced conductivity at equal rates so that a pattern of charges stored on the surface is not effected by the electrons of that energy level. As shown the target 25 comprising an electroformed nickel mesh coated with a zinc sulphide layer is disposed in a tube with a viewing screen 24, collector electrode 26, writing gun 14, erasing gun 15 with associated deflecting systems 16, 17 and 18, 19 respectively and a flood gun 20. The electrons in the beam from writing gun 14 have an energy level less than that for which the charge and discharge rates of the target are equal so that a charge pattern may be written on the surface of the target by this beam whereas the electrons in the beam from gun 15 have an energy level higher than that at which the charge and discharge rates of the target are equal, whereby any charge pattern thereon may be erased by the beam from the gun 15. The charge pattern written on the target is projected on to the viewing screen 22 by means of the flood gun 20. By means of switch 69 the energy level of the electrons from the erase gun 15 may be reduced to that at which the charge and discharge rates are equal and at that level information modulated on to this beam passes through the storage target without affecting the charge pattern thereon and is written directly on to the viewing screen. A suitable insulating material exhibiting the required characteristics is zinc sulphide in the cubic crystalline state in a layer of thickness less than 2 microns, and, to improve the secondary emission factor the zinc sulphide may be covered by a further layer of magnesium fluoride less than 1000 A thick. The cubic zinc sulphide may be produced on the conductive nickel mesh from another form of zinc sulphide e.g. by heating to a temperature of 200‹-300‹C., or by baking at 500‹C. in an atmosphere of H 2 S, or by storing a screen of evaporated zinc sulphide in the dark for at least two days.

Abstract: 626,153. Elastic-fluid turbines. AKT-GES. BROWN, BOVERI, & CIE. March 11, 1947, No. 6726. Convention date, April 3, 1946. [Class 110(iii)] [Also in Group XXVII] In a gas turbine power plant in which the pressure of the fuel gas as it is supplied to the plant exceeds that in the combustion chamber of the main gas turbine of the plant, the fuel gas before it is burnt in the combustion chamber is expanded down to the pressure of the combustion chamber in an expansion turbine which is arranged in the fuel gas stream ahead of the main gas turbine and which serves as a starter for the latter. As shown, a turbine 5 is mounted on the same shaft as a main turbine 1 and compressor 2. Gas before being supplied as fuel to a combustion chamber 6 is expanded in the turbine 5. The gas enters at a pipe 7 and is preheated at 8 by the exhaust from the turbine 1. The turbine 5 serves for starting and when so serving, by means of a cock 10, the outlet of the turbine is connected to atmosphere instead of to the combustion chamber 6. An auxiliary combustion chamber 11 supplied with gas from the pipe 7 and air drawn in at an injector 12 may be used at starting to supply combustion products to a preheater at 8 to heat the gas before it passes to the turbine 5. In normal operation the supply of gas to the combustion chamber 6 may be controlled by adjusting the nozzle valves of the turbine 5, either directly or indirectly from a power governor 9. It is stated that the expansion turbine may have one bearing only. An alternator 3 and exciter 4 are mounted on the same shaft as the turbine 1. Sealing air is supplied by the compressor 2 to all shaft glands. The Specification as open to inspection under Sect. 91 comprises replacement of the turbine 5 by a reciprocating engine. Either the turbine 5 or the reciprocating engine may supply power separately from the turbine 1. The exciter 4 could be replaced by a starter motor. This subjectmatter does not appear in the Specification as accepted.

Abstract: 340,864. Supply meters. ALLGEMEINE ELEKTRICITATS.-GES., 2, Friedrich Karl-Ufer, Berlin. Mar. 3, 1930, No. 6957. Convention date, Mar. 2, 1929. [Class 37.] The series magnet of an induction motor meter is provided with a magnetic shunt having portions which carry part of the effective flux, these portions being so dimensioned that their permeability is a maximum when the portion carrying only the shunt flux is saturated. As shown in Fig. 1, the shunt a is stirrupshaped and is stamped out of iron sheet with enlarged end portions b, b<1> parallel to the driving disc. The shunt is secured to non- magnetic strips f, f<1>, surrounding the poles e, e<1> of the series magnet d, by means of turned-down ears c, c<1>. The dimensions are so chosen that with about 150 per cent of the nominal current the portions b, bl are in the region OX of the magnetization curve, Fig. 3, and pass into the region XY with 200 per cent of the nominal current. The portion a, carrying the shunt flux only, becomes saturated at about 150 per cent. At high loads the portions c, b, c<1>, b<1> decrease in reluctance and carry a greater proportion of the working flux so that an auxiliary torque is produced which compensates for the increased braking effect. This auxiliary torque is increased by arranging the portions b, b<1> near the periphery of the driving disc.
