Abstract: 1,053,345. Casting metals. W. C. HERAEUS G.m.b.H. Nov. 25, 1963 [Nov. 24, 1962], No. 46443/63. Heading B3F. [Also in Division C7] In a method and apparatus for degassing and casting molten metals, the latter is passed through a vacuum siphon, to the inlet tube of which a carrier gas is introduced at one or more locations. The length of the inlet tube is not significantly less than the barometric height of the metal, while the outlet tube of the siphon leads into a vacuum casting chamber. As illustrated in Fig. 2, vacuum pump 3 causes metal to rise through inlet tube 4 into vessel 1 from where, with an appropriate injection of gas through inlets 5A, 5B, it can be caused to flow over weir 9 and into continuous casting mould 45 located in vessel 10, from which the resultant rod is withdrawn through pressure-reducing stages 48, 49 by rolls 52. In a modification (Fig. 1, not shown) the chamber 10 may contain a series of ingot moulds mounted on a turntable. Where gas is injected into the inlet tube at two or more locations, an inert gas flow at the upper location is used to control the flow of metal to the casting chamber, while a refining gas is injected at the lower location.

Abstract: 1,054,923. Controlling clutch-brake combination. ELECTRIC & MUSICAL INDUSTRIES Ltd. Oct. 14, 1963 [Oct. 23, 1962], No. 40054/62. Headings F2E and F2L. [Also in Division H3] Switching is effected between clutch and brake coils for controlling the intermittent movement of, for example, magnetic tape, punched cards or punched tape, by the application of switching signals from a trigger circuit to input terminals 16, 17 which in the circuit shown control the transistors 7, 11 to render either one or the other conductive. Assuming transistor 7 is condu ting, current flows in both inductor 4 and inductor 9, that in the former passing through coil 1 and that in the latter passing through diode 13. When it is desired to energize coil 2 and de-energize core 1, transistor 7 is switched off and transistor 11 is switched on. The current then formerly flowing through coil 1 is diverted to flow through diode 12 and that formerly flowing through diode 13 is diverted to flow through coil 2, these currents being maintained by inductors 4, 9 and thus ensuring a rapid switching over. Zener diodes 14, 15 prevent high voltages from overloading the collector electrodes of the transistor, and diodes 6, 10 prevent reverse currents from flowing through the coils 1, 2. Thermionic valves may be used in placed of transistors.

Abstract: 1,239,476. Marking soap bars; photochromic materials and uses thereof. ARMOUR-DIAL Inc. 17 July, 1968 [19 July, 1967], No. 33969/68. Headings C4S and C5D. [Also in Divisions H1 and H5] A method of inducing a colour change in a bar of soap comprises irradiating at least a portion of said bar with high energy electrons. The bar preferably contains a dye, such as an azo dye having a symmetrical arrangement of aromatic ring structures about the azo radical, or a mixture of dyes at least 30% of which being one of the above symmetrical dyes. Specified dyes include External D & C Red No. 8, D & C Black No. 1, " Genacryl " (Registered Trade Mark) Orange R and a mixture of 30% External D & C Red No. 8 and 70% FD & C Yellow No. 6; these dyes are effective in an amount of 0À007 to 0À15%. A multiple-colour bar of soap may be produced by directing a high energy electron radiation towards a bar of soap containing an electron-radiation-sensitive dye, and interpositioning therebetween a shielding means for directing radiation to a predetermined portion of the bar, thereby causing a change in colour of the predetermined portion of the bar only. The shielding means may comprise a sheet of electron-radiation-impenetrable material having an indicia aperture cut thereinto, said indicia being penetrable by at least a portion of said high energy electron radiation so as to cause the configuration of the indicia to be applied to the bar of soap by exposure to the radiation; preferably the indicia aperture is tapered through the sheet (Fig. 7, not shown) to conform the aperture to the path of the radiation. The shielding means may also comprise a sheet of electron-radiation-penetrable material having an affixed indicia, impenetrable to high energy radiation, whereby the configuration of the indicia is applied to the bar by exposure to the radiation. Thus, lead indicia on rubber latex may be used (Fig. 5, not shown). In the examples, bars of germicidal soap containing sodium coconut soap, sodium tallow soap, 3,4,5- trichlorocarbanilide and hexachlorophene are coloured according to the method of the invention. Toothpaste and cleansing creams are also exemplified. Reversible dyes may be employed and examples thereof include photochromic azo dyes, methylene blue, quinone, azobenzene, 2,3,5 - triphenyl - 2,4 - tetrazolium chloride and generally as in Tables IVA and IVB. The dye is preferably initially absorbed on titanium dioxide to improve intensity and clarity.
