Title: Improvements in the method of, and machines for, making corded tyre covers
IPC: B29D30/38
Filed: 1926-04-19
Abstract: 250,978. Debor, H. April 20, 1925, [Convention date]. Tyres, elastic, special apparatus for making.- Corded tyre covers are formed by squirting a coating of rubber on to rotating formers and winding cords spirally thereon under tension. The machine for making the covers comprises a main frame a upon which are mounted, by means of spindles d, d<1>, the tubular formers c, the spindles d carrying pinions e by means of which they are rotated. Also mounted upon the frame a at each side thereof are screw spindles g which with members h, connected by a bar k, comprise the traverse mechanism for the covering cords. The cords are passed through a container p of rubber solution, thence between grooved rollers q which remove the excess solution and also tension the cords. In operation, the formers c are coated with rubber by squiring and the cords are wound on the rubber while it is still soft, the formers c and the spindles g being rotated continuously by means of a pulley n, the cords being guided on to the formers c by eyes i on the bar k. A bar k<1> is pivotally mounted on the bar k so that it can be swung down to clamp the cords when the winding is completed, the cords being then cut and the formers c withdrawn for removal of the finished covers. Means arc provided for adjusting the relative speeds of the formers c and spindles g, and the spindles d<1> are held in position by springs to facilitate removal of the formers.

Title: Improvements in or relating to a Liquid Seal for a Gas Pipe Line
Inventor: BELL ANDREW
IPC: F16K13/10
Filed: 1967-03-04
Abstract: 1,165,821. Liquid seals. JAMES HOWDEN & CO. Ltd. 4 March, 1968 [4 March, 1967], No. 10348/67. Heading F2V. A liquid seal for a gas pipe-line comprises a vessel 4 for liquid, an upright partition wall 6 in the vessel forming a U-passage, an inlet duct 2 projecting downwards into one limb 12 of the U-passage to dip into the liquid, an outlet duct 3 extending from the top of the limb, pressure reduction means 16 assoiated with the outlet duct and operable on flow of gas through the duct, and a conduit between the pressure reduction means and the top of the other limb, the arrangement being such that the gas flow in the outlet duct causes the liquid level to fall to a position clear of the bottom of the inlet duct to permit flow of gas above the liquid to the outlet duct and on stoppage of the gas flow the liquid seals the inlet duct. The inlet duct has a rectangular nose portion 2A which projects downwards into a tube 6 forming the partition wall and containing a rectangular baffle plate 18. A Venturi may be used to lower the pressure in the limb 11 and to cause a corresponding fall in liquid level in the limb 12. The Venturi 16 may be disposed within the outlet pipe in parallel with a large orifice plate or it may be replaced by vortex-producing vanes. In a further modification, the outlet pipe projects into the limb 12 of the U-passage and is surrounded by the inlet pipe which is connected directly to the top of the limb, the gas conduit extending across the annular space between the pipes to a throat in the outlet pipe.

Title: Constant-power electrical supply means
Inventor: MASON GUY
IPC: G05F1/33
Filed: 1963-03-18
Abstract: 1,008,449. Automatic power control. HIRST ELECTRONIC Ltd. June 17, 1964 [March 18, 1963], No. 10696/63. Heading G3R. In a constant power electrical supply system, signals respectively proportional to current and voltage combine to produce pulses the'integral of which, representing power, is applied through a D.C. amplifier to control the power supply. In Fig. 1 the power supplied from A.C. mains 11 through a transformer 13 to the heating element 14 of an electric furnace is automatically controlled by a saturable reactor 12 the A.C. windings of which are in series with the transformer primary. The output of a current transformer 24 associated with the load is rectified at 26 and combined in a generator 27 with a voltage of triangular waveform to produce width modulated pulses of constant amplitude and frequency which are applied to an amplifier 29 the gain of which is automatically varied in dependence on the rectified output of a load voltage transformer 25. As a result a resistance-capacity integrator 30 produces a direct voltage dependent on the power supplied to load 14 and any difference between this voltage and an adjustable stabilized reference voltage from a unit 23,representingthe desired supplied to load 14 and any difference between this voltage and an adjustable stabilized reference voltage from a unit 23, representing the desired power, is effective through a network 22 and a high gain negative feedback amplifier 21 to control the current in D.C. windings 12<SP>11</SP> of the saturable reactor and thereby maintain the power supply at the desired value. In a modification for non-resistive loads, the secondary winding of the voltage transformer is centre-tapped and the rectified output of each half controls separate variable gain amplifiers applying pulses of opposite polarities to integrator 30 to allow for phase displacement between load voltage and current. Use of silicon controlled rectifiers or ignitrons in place of the saturable reactor and application to the control of D.C. or three-phase supplies are referred to.

Abstract: 258,807. Sheppard, A. H., and Ever Ready Co. (Great Britain), Ltd. April 23, 1926. Cases; cells; connections.-In order to provide for the testing of batteries having plug socket terminals while preventing their continuous use baffles are provided to partly cover the openings of the sockets. The baffles may take the form of paper strips pasted across the sockets. The strips may be narrower than the sockets to provide spaces for the insertion of testing wires &c. or a small hole may be provided in a wide strip completely covering the socket. Alternatively a strip of. paper may be fixed so that one edge crosses the mouth of the socket. In other arrangements openings of various shapes are provided in the cover of a casing which completely encloses the battery. Figs. 4 and 5 illustrate two modifications in which circular openings are provided above the sockets, the openings being crossed by bars or strips 16 to prevent the insertion of a full-size plug. Smaller plugs or wires may be inserted in the spaces 15 for testing. Instead of circular openings, openings of cruciform shape or narrower slots may be formed in the cover. Circular openings without baffles may be provided, the openings in this case being either too small for the insertion of a plug, or placed eccentrically so that the edge of the opening crosses the mouth of the socket.

Title: Preparation of aliphatic acids
Filed: 1960-03-25
Abstract: Saturated aliphatic acids are made by ozonizing unsaturated fatty acids, decomposing the ozonide so formed by heating it, e.g. at a temperature between 80 DEG C. and 130 DEG C., and oxidising the resulting decomposition products to produce the saturated aliphatic acids, there being present, at least during the decomposition step, a phosphorus oxy-acid or an ester of such an acid, e.g. orthophosphoric acid, pyrophosphoric acid, metaphosphoric acid, phosphorous acid, polyphosphoric acids, phosphoric anhydride, tricresyl phosphate, trioctyl phosphate, tributyl phosphate, triethyl phosphate, ethyl metaphosphate, butyl pyrophosphate and octyl phosphite.  The preferred starting material comprises at least one unsaturated fatty acid containing a chain of 6-8 saturated carbon atoms on at least one side of the double bond, such as rice bran oil fatty acid, tall oil fatty acid and commercial oleic acid.  The oxidation step may be effected, preferably simultaneously with decomposition of the ozonide, by heating in the presence of manganese acetate while passing in oxygen.  Prefered proferred products are caproic, pelargonic and azelaic acids.
