Convention date, Aug. 2, 1930. [Class 97 (i).] The supports for the pay-out and take-up spools are differently constructed, and the spools are so constructed that they may be mounted only in one particular relation to one support and in a different relation to the other support. As shown, the supports comprise spindles 11, 12, respectively provided with rings of teeth 19, 20, the numbers of teeth in the two rings being different. The spool has teeth 17, 18 in the spindle holes of the flange 15, 16, the numbers of teeth in the two flanges being such that they will respectively mesh only with the teeth 19 and with the teeth 20. The teeth 19 provide a driving connection with the teeth 17 of the spool, but not with the teeth 18, thus ensuring that the spool shall be correctly mounted on the spindle 11 with the flange 15 towards the plate 10. The teeth 20 are so placed on the spindle 12 that they do not engage either set of teeth in the flanges when the spool is properly mounted on the spindle, but prevent the spool from being mounted with the flange 15 towards the plate 10 ; the teeth 18 may, however, pass over them, so that the spool may be mounted with the flange 16 towards the plate 10.

Abstract: A heat-resistant material is prepared by heating a polyphosphonitrilic chloride with a naturally occurring calcium or magnesium silicate in the form of discrete particles or fibres at a temperature of at least 300 DEG  C. to effect reaction therebetween. Preferably, an oily polyphosphonitrilic chloride admixed with asbestos or mica, with or without slate is heated in a mould at a temperature below 300 DEG  C. for a period, and is thereafter heated in an oven at 300 DEG  C. or above to effect the reaction.  There may be included in the reaction mixture a substance, e.g. litharge, which will react with the formed calcium and magnesium chloride to form an insoluble chloride.  Inert fillers or fillers of low reactivity with polyphosphonitrilic chlorides, e.g. alumina, carborundum, titanium carbide, silica and graphite may also be included.  In an example, a mixture of 70 parts by weight of asbestos fibre and 30 parts of oily polyphosphonitrilic chloride is heated in a mould under pressure at 175 DEG  C. for one hour, and then heated at 300 DEG  to 350 DEG  C. for three hours.  It is also stated that the material may be formed as laminated asbestos cloth, felt, or paper and used for heat resistant gaskets.ALSO:A heat-resistant material is prepared by heating a polyphosphonitrilic chloride with a naturally occurring calcium or magnesium silicate in the form of discrete particles or fibres at a temperature of at least 300 DEG C. to effect reaction therebetween.

Abstract: 423,362. Changing signs. WARNER, A. R., 29, Abbey Road, St. John's Wood, London. July 25, 1933, No. 20914. [Class 3 (i)] [See also Group XL] In an electric luminous discharge tube apparatus for use with animated signs and supplied with variable voltage high-frequency currents, a capacity effect is produced between the luminous discharge and a plate or conductor connected to the energizing circuit, the capacity being so distributed that the luminosity commences at one end and spreads along the tube. The plate serves also as a screen preventing the diffusion of an electrostatic field whereby interference with neighbouring radio apparatus is avoided. As shown applied to a sign giving the effect of writing, a plate PL at the back of the tube T is connected to one terminal of a high frequency generator G which may be of the type described in Specification 399,566, the other terminal of the generator being connected to the tube electrode E1. The second electrode E2 may be left unconnected or connected to the plate. The plate PL is inclined to the tube or curved away as shown in Fig. 4, and when an increasing voltage is applied to the tube, the luminosity spreads from the electrode E1. At points of intersection, those parts of the tube to light up first are placed farther from the plate than the following portions. The spacing of the plate is preferably adjustable. In order to obtain uniform illumination, the plate does not extend as far as the electrode E1.

Abstract: <PICT:0741900/III/1> <PICT:0741900/III/2> In a method of drying, baking or similarly treating materials by contact with a stream of heated gases in the course of which treatment oxidizable fumes are given off into the gas stream and the effluent gases containing such fumes are conducted to a zone where they are contacted with an oxidation catalyst under conditions permitting substantially complete oxidation of the fumes before recirculation of the gas (Group XIII) catalysts are prepared by dipping catalytically active alumina in solutions of salts of copper, chromium, vanadium manganese, molybdenum, silver, nickel, cobalt iron, magnesium, platinum, palladium, ruthenium or combinations of these metals followed by thermal or chemical decomposition of the metal salts Catalytically active magnesia, beryllia or thoria may be substituted for the alumina. The unit supporting the catalyst consists of end plates 24 having a plurality of apertures for receiving rods 25 to support them in spaced relation, one end being freely supported to allow expansion and the plates being fastened together by a single central post surrounded by the rods.  To ensure a minimum pressure drop through the unit the rods 25 are streamlined in contour having a rounded leading edge 26 and a tapered trailing edge 27.  The unit is composed of high quality porcelain with the catalyst disposed thereon in a thin tightly adherent film such as a thin coat of active alumina to which platinum is added by dipping in a solution of the metal salt with subsequent thermal or chemical decomposition. The catalyst bed is made up of a number of units stacked one upon the other in rows and layers.  In order to bring the catalyst up to operating temperature (a minimum of 500 DEG F with platinum-onalumina) a gas burner is provided and is turned off when the concentration of combustible vapour reaches a level sufficient to retain the bed at the required temperature.  To keep below the maximum permissible operating temperature (2100 DEG F with platinum-on-alumina) the vapour concentration and temperature is controlled by a heat-exchanger and by recirculating large volumes of gas.  Cooling may be necessary when large quantities of combustible vapour are evolved.
