Filed: 1953-12-04
Abstract: 747,438. Belt fastenings. DAYTON RUBBER CO. Dec. 4, 1953 [Dec. 5, 1952], No. 33764/53. Class 80(1) The ends of a driving or conveyer belt of textile and rubber-like material are compressed during manufacture to a greater density than the remainder of the belt in order to increase the pull-out strength of the belt fastener employed therewith. In the fastener shown, looped straps 11 are secured to the ends of a belt by nails, rivets or the like and are interconnected by a link 14 and pin assemblies 15. The belt shown consists of upper and lower sections comprising layers of straight- or biaslaid rubberized fabric, and a neutral axis section 18 comprising one or more layers of helically wound cord, the upper and lower surfaces of the belt ends being indented to form neck portions held within the straps 11. In a modification the cords in the neutral axis section are replaced by one or more layers of square-woven straight-laid rubberized fabric, and only the upper surface of the belt is indented. In modifications employing rubber belting comprising only a little textile material, the rubber is prevented from flowing while it is compressed to form the indentations, by the use of compounding expedients or by partially curing the rubber before compressing it. In one method of construction, a belt sleeve 32 is formed on a rotatable mandrel and inner and outer strips 33, 34 of wood, metal or the like are arranged thereon so that on the application of compacting means such as a rag wrapper 35 the sleeve is compressed to an increased density between the strips, the whole assembly being then vulcanized, after which annular belts are cut from the sleeve and then cut through the necked portion to provide belt ends of greater density. In another method of construction a strip of V-belting comprising upper and lower sections of rubberized bias fabric, a central section of straight-laid fabric and a rubberized fabric cover encasing the whole, is vulcanized in an individual mould, the belt ends being compressed by upper and lower plates in the mould. If desired, one compression plate may be omitted.

Filed: 1973-07-16
Abstract: 1441038 Catalytic methanation SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 16 July 1973 33777/73 Heading C5E Methane-rich gas is produced by vaporizing liquefied methane-containing gas, e.g. liquefied natural gas, by heat exchange to yield liquefied air in addition to the methane-containing vapour, partially combusting a gaseous, liquid or solid carbonaceous fuel with a free oxygencontaining gas, at least a proportion and perhaps all of which is obtained by separating an oxygenrich stream from the liquefied air, mixing the gaseous combustion products with a part of the methane - containing vapour, catalytically methanating the mixture, and mixing the product gas which may contain 90 to 100% by volume methane with the other part of the methane-containing vapour. The gaseous combustion products may be cooled, e.g. by water injection, to between 650‹ and 1100‹ C., carburetted by injection of a hydrocarbon fuel, e.g. naphtha and/or kerosene, and then further cooled, e.g. in a waste heat boiler generating high pressure steam, prior to the mixing with the methane-containing vapour such that the carbon monoxide in the gases being catalytically methanated is 1 to 10% by volume. Catalytic methanation may be in at least two stages, the first being at a higher temperature than the following stages, and the methane-containing vapour is in part added to the gaseous combustion products prior to the first stage and in part injected between stages. Carbonaceous fuels specified are petroleum fractions, residual hydrocarbon oil and coal. The air may be liquefied by direct heat exchange, or indirect heat exchange using an intermediate inert gas liquefication stage, e.g. using nitrogen. The gaseous combustion products may be subjected to a catalytic CO-shift conversion and subsequent CO 2  removal immediately prior to the catalytic methanation of the gaseous products.

Abstract: 1,104,791. Cathode-ray tube circuits. MULLARD Ltd. 27 Nov., 1964 [27 Aug., 1963], No. 33875/63. Heading H4T. Relates to an electromagnetic frame deflection circuit for a cathode-ray tube (C.R.T.) with a rectangular raster, comprising deflection coils Lc and a transductor TD with a control winding Lw fed from a line-frequency signal source for varying the deflection current in coils Lc so as to effect " north-south " raster correction. According to the invention the transductor has a main winding Lv on its saturable core connected in parallel with coils Lc, means Ldc for biasing the core at an operating point within a substantially linear part of the transductor permeability characteristic, the signals fed to winding Lw have a substantially symmetrical curved waveform and constant amplitude, and a paralleltuned circuit A tuned substantially to the line frequency is inserted between the frame deflection current source and the parallel combination of coils Lv, Lc. The frame frequency current Ic amplitude-modulation envelope is linear, Fig. 2 (not shown). The C.R.T. may be a wide deflection angle monochrome, or a colour television " shadow-mask," tube. A second circuit, B, tuned to the line frequency, reflects a high impedance across winding Lw and the line frequency current in the latter is of sinusoidal form. The line frequency signal is taken from conventional boost capacitor Cb. A necessary 90 degrees phase-shift correction is afforded by network Rpl, Rp2, Rp3, Cp. The amplitude of modulation current is adjustable by resistors Rv, Rw. For greater transductor efficiency winding Lw may be series-tuned by a capacitor and that tuned circuit is driven by voltage fly-back pulses from a separate winding on the line output transformer, Fig. 7 (not shown).

Preferably, the reagent added to develope the colour change is supplied in proportion to each quantity of filtrate.  In the colorimeter two beams of light are generated, one of which passes through the flow-cell, and the other through standard light filters; the emergent light beams being then received on photo-electric cells actuating a recorder.  A conventional chromatographic column 14, Fig. 1, is supplied with a predetermined quantity of a solvent fed through a proportionating pump 12, and the resulting filtrates pass through an outlet 40 where they are mixed with predetermined amounts of a colour-developing reagent fed by a proportionating pump 13 through a pipe 34.  If necessary, the mixture may be heated in a bath 16 to develope colour and is then cooled in bath 18 before passing to the colorimeter 20.  This comprises a double-light beam instrument in which a light source 52, Fig. 2, is enclosed in a shield 54, provided with apertures 56, 58 giving two beams 60, 62.  The light beam 60 after reflection at a concave mirror 64 passes through fixed light filters 68, flow-cell 90, to photo-electric cell 118. The second light beam after refiection at a concave mirror 120 passes through fixed filters 124, standard filter 128 to a filter assembly is provided with a rotatable light filter 136, 138 operated by a motor 160.  The fixed light filters transmit light of a predetermined bandwidth and the rotary light filters select light of a predetermined wavelength within the band.  Both the standard filter and the flow cell are subjected simultaneously to light of the same wavelength.  The coloured filtrates from the line 48 flow without turbulence into the flow-cell 90 which is of U-tube form connected to a vertical tube outlet through which the liquid overflows to a drain.  The multiple recorder unit 22 consists of an engraved print wheel and inking pad assembly 182, which moves transversely to the paper in accordance with signals received from photo-electric devices 118, 132.  The motor operates the rotating light filters 136, 138 in synchrony with the printing wheel of the recorder, whereby individual light filters are related to specific printing symbols.  The rotating light filters operate a switch through gearing and cams, whereby the recorder is energized when the light filter is in alignment with the fixed filters and the standard filter or the filtrate under test, and de-energized in intermediate positions of the rotary light filter.
