Abstract: 1,071,277. Abrasive tools; milling; brazing. DEXCO CORPORATION. Jan. 28, 1966 [Jan. 29, 1965], No. 3850/66. Headings B3D, B3K and B3R. A tool having a surface capable of cutting workpieces of relatively hard materials or of relatively soft resilient materials is made by (a) providing myriad discrete grits of tungsten carbide having a generally predetermined size, (b) providing a substrate having a bonding surface of a material with which the tungsten carbide will form a bond and which has a melting-point higher than that of copper, (c) providing a brazing compound in fluent form which contains a generally predetermined amount of copper and flux, (d) applying to the bonding surface a coating of the compound and a layer of the grits, the amount of copper being substantially no more than that necessary, when molten, to wet the grits and form a layer between the grits and surface, (e) heating the surface material, compound and grits to at least the melting-point of the surface material and thereby causing a fused metal connection to form between the grits and surface material, (f) and then cooling the assembly thereby formed to solidify the materials forming the connection. The tool may be a disc-shaped wheel having grits on its periphery or side faces, or a rectangular hone stick of the type used in honing cylinder bores; it may have peripheral teeth for engagement with the teeth of a gear to be honed or may have the general configuration of a shaving tool with the individual cutting edges removed, the tool resembling a worm. The substrate is of metal of suitable rigidity and hardness, e.g. steel. The surface is preferably shot-blasted (Fig. 2) and after cleaning, if necessary, with a solvent, is heated to approximately 200 F. by a torch (Fig. 3) or in a non- oxidizing atmosphere in an oven. A nickelchromium alloy having a melting-point of 2000-2100 F. is then flame-sprayed on the surface (Fig. 4) to form a bonding layer of a thickness 0À001-0À015 inch according to the size of the grits to be used. After cooling, a brazing compound, to which is added a fluxcontaining material and sufficient solvent to give the required viscosity, is applied to the bonding layer by painting or spraying (Fig. 5) to a thickness of 0À001-0À015 inch according to the size of the grits to be used. Tungsten carbide grits are then sprayed on (Fig. 6) forming substantially a single layer retained by the brazing compound. The article is then heated, preferably in a non-oxidizing atmosphere in a furnace, to cause melting of the bonding layer.

Title: Improvements in and relating to electrical sound transmission systems
IPC: H04S1/00
Filed: 1935-02-07
Abstract: 456,444. Binaural and directional systems; microphones. BLUMLEIN, A. D., 7, Courtfield Gardens, West Ealing, London. Feb. 7, 1935, No. 4037. [Class 40 (iv)] [See also Group XL] In a transmission system using a number of microphones, a final output having an order of directivity higher than the first is obtained by passing the microphone outputs, in combinations, through two successive networks each converting phase differences into amplitude differences in a manner similar to that described in Specification 394,325. An output having the first order of directivity is one in which the amplitude depends on cos #, where # is the angle between the direction of the sound source and the normal direction face on to the microphone assembly. Each network introduces a factor dependent on cos # so that with non-directional microphones, the final output is of the second order whereas with directional (moving-strip) microphones, it is of the third order since the output of a directional microphone is dependent on cos #. In the arrangement shown in Fig. 1, the outputs of four microphones 1-4 are passed, in pairs through " shuffling networks 5, 6 which may be of the nature described in the above-mentioned Specification or may involve delay, attenuation or amplification effects to produce a similar result. Two outputs, one from each of the networks, are again shuffled at 7 to produce final outputs having the desired directional characteristics. A single output may be used, but where binaural effects are required separate loudspeakers 8, 9 are used for two outputs. When directional microphones are used, they may take the form shown in Fig. 4 comprising a single strip 10 supported or clamped at five points to provide four microphone elements. The strip is mounted between the polepieces of a magnet, the polepieces being cut away, especially near the middle of the strip, to minimize baffle effects. The sound range may be divided into two bands which are treated separately and re-combined, and the arrangement of strip microphones shown in Fig. 5 is suitable for this purpose, the strip 11-14 being nearest the sound field. The low frequency band is dealt with by the outer pairs of elements 11, 14, 17, 18 whereas the inner pairs 12 .. 16 deal with the high frequency band. After the outputs of the high and low frequency elements have been treated as above, they are combined in a network as described in Specification 429,022 or as shown in Fig. 3. The outputs of the low and high bands are fed to terminals A, A<1> and B, B<1> respectively, A being connected to B and the combined output being derived at 0, 0<1>. The transmission may include a recording and reproducing link. According to the Provisional Specification, the invention may be applied to confine the field of sound radiated by a number of loudspeakers.

Title: Improved glass having an expansion lower than that of silica and process for the manufacture thereof
IPC: C03C3/076
Filed: 1940-03-07
Abstract: 538,891. Glass manufacture. CORNING GLASS WORKS. March 7, 1940, No. 4290. Convention date, April 22, 1939. [Class 56] A refractory glass having a co-efficient of expansion less than that of pure fused silica is made by introducing the vapours of silicon tetrachloride and titanium tetrachloride into the gas stream of an oxy-gas burner, depositing the resultant mixture of oxides on a former, and vitrefying the deposit. The proportions of the two vapours are regulated to produce a glass containing 89-95 per cent. of silica and one 5 per cent., but not over 11 per cent. of titanium oxide. Part of the silica and titania may be replaced by alumina or zirconium oxide in an amount not exceeding 5 per cent. The deposit when vitrified at a temperature of 1500 C. forms an opal glass which may be heated further to 1600C. or higher to cause it to become transparent. Apparatus for making the glass may comprise a flask 11, Fig. 1, containing a liquid mixture of silicon tetrachloride and titanium tetrachloride, which is supported in a constant temperature bath 12, and tubes 13, 14 for leading a combustible gas into or out of the flask. A byepass value 15 connects the tubes 13, 14 to regulate the introduction of the vapours into the gas stream. The mixture of gas and vapour is conducted to a burner 18 after receiving a controlled amount of oxygen from a tank 17. The vapours are decomposed by the heat of the flame and the combustion products, composed of an anhydrous mixture of silica and titania, are deposited on a rotating mandrel 19, where it builds up into a coherent amorphous tubular shape. The tube may be vitrified after removal by suspending it in an electrically heated furnace or a gas-fired muffle with an oxidizing atmosphere. If desired, the liquids may be vaporized from separate containers connected in series or in parallel, and steel bottles may be used instead of glass flasks. When alumina or zirconia is to be introduced into the flame, the vapour generator comprises a cylindrical metal barrel 38, Fig. 4, provided with a burner tip 41 and containing a refractory boat 39 and baffles 40. A tube 47 for introducing combustible gases and vapours, and a thermometer 46, are inserted through a cover plate 42. Aluminium chloride or zirconium chloride is placed in the boat 39, and the barrel 38 is headed by an electric heater 43 to cause the salt to evaporate at the desired rate. Specification 438,782 is referred to.
