Title: Improvements in or relating to color cinematographic films and method of making same
IPC: G03B33/00
Filed: 1922-10-31
Abstract: 188,329. Technicolor Motion Picture Corporation, (Assignees of Comstock, D. F.). Nov. 2, 1921, [Convention date]. Colour photography.-In the production of kinematograph films comprising components bearing sets of differently coloured relief images, the components being superposed after the coating on each has been exposed through the back, the superposition is effected before the images are developed, and the components are cemented together back to back. As shown, a doublewidth silver-sensitized film, which is folded to a single width as at A for perforating, is opened out as at C for printing, the printing being through the back. The film is again folded, with the images outwards, before development and treatment of the images, and the parts are subsequently cemented together. The treatment of the images may consist in developing with a developer such as pyro, which hardens the gelatine in the immediate neighbourhood of the silver, bleaching with potassium ferrocyanide, fixing with hypo, etching away the soft gelatine, and staining the relief images .so obtained. The gelatine on the margins of the film may be completely removed. The images may be taken from the same view point. Specification 194,971, [Class 97 (i), Optical systems &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) also states that the film may be folded with the images inwards, the components may be uncemented, the development may precede the folding, and the images may consist of homogeneous transparent colloid reliefs free from opaque or merely translucent light-absorbing bodies. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the distillation or carbonisation of carbonaceous materials
IPC: C10G1/02
Filed: 1921-11-10
Abstract: 192,515. Nielsen, H., and Laing, B. Nov. 10, 1921. Coking processes.-In this distillation of carbonaceous materials the heating medium consists of hot combustion gases which, after being utilized for distilling purposes and being thereby enriched with combustible gases are admixed with air and re-ignited for the purpose of subjecting further quantities of materials to heat treatment. A producer A is used when starting to supply gas to a combustion chamber B the combustion products entering and heating a rotary retort C, the mixed distillates and combustion products passing through a cyclone dust extractor D condensers E and oil washer F. The hot coke is collected in an annular chamber c and is discharged on to a conveyer c<1> and the condensed tar oils are led away by a pipe G. The stripped gases are then ignited in combustion chambers B<1> with air supplied by a fan K and the hot gaseous mixture passed through retorts c' the coke being removed as before and the stripped gases from the condensers E<1> and oil washers F<1> passed to further retorts C<2> where operation is repeated the resulting gases finally being burned to heat steam generators I. If low temperature distillation is required a large volume of inert combustion gas is admitted whereby the incomplete combustion takes place. After starting, the producer A may be cut out and gases by-passed by a pipe J used in the combustion chamber B. In lieu of burning the producer gases their sensible heat mav be utilized in retort C, or where the temperature of the gaseous mixture permits, its sensible heat may be used to heat any of the retorts. A combined high and low temperature process may be carried on.

Abstract: Metalliferous materials which are solid at the temperature of molten magnesium and which contain metals, the oxides of which have a heat of formation less than that of magnesium oxide, are heated in the form of pieces or lumps greater than 1 mm. in diameter with metallic magnesium in a closed vessel at a temperature sufficient to melt the magnesium.  The reaction may be carried out in an iron cylinder provided with lids at each end, a pressure safety device comprising an iron tube, one end of which communicates with an aperture in the top cover and the other end of which dips below the surface of an oil bath, being provided: to prevent oil sucking back, a U-bend may be provided as described in Specification 444,957.  The dross obtained in the reaction may be again reduced to magnesium in an aluminum bath and the magnesium recovered by distillation.  Calcium, barium, or strontium or alloys of these metals with magnesium may be produced using the oxides as starting materials or an alkaline-earth-silicon-magnesium alloy may be formed by using the silicate.  The oxide dross produced by the process described in Specification 397,844 may be treated by the process, for example, a dross consisting of beryllium oxide, aluminium oxide and metallic aluminium, formed by adding beryl to molten aluminium, in accordance with Specification 397,844, may be introduced into a bath of molten magnesium to form an aluminium-beryllium-magnesium alloy. Alternatively, the dross may be submitted to an oxidizing roast prior to treatment with magnesium, when a magnesium-beryllium alloy is produced from which the magnesium can be removed by distillation. The process may also be applied to the extraction of tin, chromium, vanadium, uranium, nickel and the rare earth metals.
