Abstract: 1,023,030. Tyre repair plugs. O. GRUBER, and W. GRUBER, [trading as STAHLGRUBER OTTO GRUBER & CO.]. Aug. 13, 1963 [Aug. 13, 1962; May 18, 1963], No. 31970/63. Heading B7C. Holes in tyres are repaired by inserting repair elements (Figs. 1 . . . 8) which comprise sections of elastic vulcanized rubber embedded in plastic unvulcanized rubber, the unvulcanized rubber serving to vulcanize the element into place, but some rubber remaining permanently unvulcanized. In Fig. 1 (not shown) layers (1), (2) are unvulcanized, centre layer (3) is vulcanized rubber, the element shown being of strip form. More layers may be employed (Figs. 2, 5, not shown), and elements may be of cylindrical shape with cords (9) of vulcanized rubber (Fig. 7, not shown), or of rectangular section (Fig. 8, not shown). Elements may be constricted in the middle (Fig. 6, not shown). Outer layers of unvulcanized rubber (2), (10) (Figs. 1, 7), only, may contain sulphur or accelerator to vulcanize the rubber on contact with vulcanizing fluid or paste, or all the unvulcanized rubber may include sulphur or accelerator, since only the peripheral parts will in fact be exposed to the liquid or paste. Fig. 9 (not shown) illustrates a tool comprising a roughened or threaded cylinder 13 mounted in a handle 14 and carrying a bent wire head (12) which forms an eye 18. The cylinder 13 is axially adjustable in the handle 14. In use, a repair element is bent double (Fig. 1), and inserted in eye 18. The element and tool are dipped in vulcanizing paste and pushed through the hole in the tyre as shown, which has been abraded by cylinder 13 and lubricated. The element is stretched in inserting, but the elastic vulcanized sections restore its shape when the tool is withdrawn (Fig. 12, not shown), the outer unvulcanized sections filling the hole before being themselves vulcanized by the paste, and the inner unvulcanized sections remaining plastic. A hole may be filled by more than one element, and elements need not be bent double in use.

Drawings to Specification. [Class 37] A moving element under an electric or magnetic field such as is used in a galvanometer voltmeter &c. is completely immersed in a liquid preferably of the same density as the mean density of the element so that the whole or a large part of the weight of the element is compensated for. The element may be of elongated shape moving longitudinally in a tube containing the liquid and to obtain a low density the magnetic or soft iron bar or copper wire coil may be combined with material of low specific gravity or be in the form of a closed hollow body. A returning force may be applied by an auxiliary field or by a spring. To meet the effect of variation of temperature on the liquid, which may be water, solutions such as of caustic soda, or alcohol, or bromoform, the moving element is enclosed in such materials as will result in its having the same mean coefficient of expansion. Thus for use with water an element may comprise an ebonite tube-which has approximately the same thermal coefficient of expansion as water-with a sheet of soft iron rolled in the form of a tube inside or outside of it. Again, the end of the outer tubular container may comprise a small bellows to the outer end of which the end of the spring return is secured so that the tension of the spring is varied. In a modification the scale has a variable position according to the temperature. A further modification describes the application to a moving coil rotating in a cylindrical receptacle.

A safety device for a radiation burner 6 comprises a control burner having a nozzle 9 located behind an orifice 25 in the radiation plate 26 and means responsive to the flame of the control burner to control the supply of gas to both the radiation and the control burners. The flame responsive means comprises a thermocouple 21a located in a tangential position with respect to the flame of the nozzle 9 and adapted to energize an electromagnet to hold a lever, for operating a valve controlling the supply of gas to the radiation burner and the nozzle 9, in the open position of the valve. The lever has an armature plate and, in order to prevent adhesion to the electromagnet due to residual magnetism, the plate is coated with copper electrolytically or with paint or with a non-magnetic film obtained by metallization. The end of the nozzle 9 has an interior taper and the gas is supplied thereto by an injector. The nozzle 9 is disposed in a sleeve 23 passing through the gas chamber 24 of the radiation burner. The radiation burner and the control burner cause a draught to flow through the sleeve 23 which cools the nozzle 9. The control burner extinguishes when the concentration of carbon dioxide in the atmosphere is less than 0.4%.

Abstract: 638,621. Electron discharge apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 5, 1945, No. 32847. Convention date, Dec. 5, 1944. [Class 39 (i)] [Also in Group XL (c)] A valve acting as a limiter has a virtual cathode and means for exerting a control thereon whereby with increasing signal voltage the current from the virtual cathode to the anode rises and then falls and afterwards remains substantially constant or again increases or does not fall to a value approaching zero. To produce the same characteristic, an electron beam deflection valve may have an intercepting electrode so shaped that with increasing voltage applied to the deflecting means the interception of the beam by the intercepting electrode varies in the required manner. In one embodiment, Fig. 5, the amplitude limiter valve 1 comprises a cathode 2, signal input grid 3, accelerating grids 4, 6, anode 7 and a non-uniform retarding grid 5 between grids 4 and 6. The non-uniformity of electrode 5 may be provided by a gap 8 therein or otherwise. The control grid potential anode current characteristic may take the forms F, G, H, Figs. 4a, 4b, 4c, or intermediate forms depending on the potential of electrode 5. The valve may be provided with two non- uniform retarding electrodes separated by an accelerating grid, Fig. 6 (not shown). In a beam deflection valve of the type described in Specification 561,459, the beam 32, Fig. 7, is deflected by the signal applied to electrodes 33, across an intercepting electrode 36. The latter may have the shape shown in Fig. 8 or Fig. 9, and may act as the anode, the electrode 35 being made secondary-emissive. Alternatively, secondary electrons may be suppressed by adding an additional suppressor aperture electrode of known type.
