[Also in Division G4] In a measuring system Fig. 3 the "fine" angular position of a shaft within one tooth-pitch is represented at terminals 81, 82, 91, 92 by four A. C. amplitude significant signals, these being obtained by four pairs of diametrically opposite sensing heads 611,611a; 611b,611c; 612, 612a; and 612b, 612c, the heads being spacially phaseshifted from each other, with respect to a tooth pitch, by 90 degrees. The coarse position of the shaft is obtained by brush-sensed conductive and non-conductive regions 800 &c. The four A.C. signals can be suitably combined and attenuated (Fig. 4 not shown) to give a digital fine indication or, before digitisation, they can be suitably combined to produce a corresponding phasesignificant A.C. signal. (Fig. 5 not shown). A modified form of tooth is described (Fig. 3a not shown).

Title: Improvements in and relating to three-colour photography
IPC: G03C7/26
Filed: 1920-04-20
Abstract: 168,100. Gorsky, S. M. de Procoudine-. April 20, 1920. Colour photography; toning.-Relates to a process for the production of fully coloured positive pictures comprising three superposed component pictures from negatives taken through colour screens, and particularly applicable to the production of kinematograph films by the process in which a film negative is taken having recurring series of images taken through three filters, the images taken through each filter being printed in superposition on a single film. In printing each positive from a kinematograph film as described above, the negative film is fed through three picture spaces at each shift. In the present process the positive printed from the negative of violet-blue sensation is coloured yellow by means of a solution of auramine in the presence of basic aluminium acetate. The positive, after printing, is treated with a solution of potassium ferricyanide, potassium iodide, and ammonium hydrate, washed, and then immersed in the solution of basic auramine in the presence of acetic acid and basic aluminium acetate. The print is then fixed. The superposed positive from the negative of green sensation is toned or coloured red by using rodamine in the presence of acetic acid, and the positive from the negative of yellow sensation is toned or coloured blue by treatment with potassium ferricyanide and ammonia followed by treatment with ferric chloride, hypo, and finally dilute sulphuric acid. The filters used in taking the negative are methyl violet 6B, brilliant green, and Bengal rose. A quantity of tartrazine is used with the red and green filters, and an aesculin filter with the violet filter to eliminate ultra-violet rays. After printing each positive and prior to resensitizing, the film is treated with a solution of tannin and glycerine, the former hardening the film and the latter keeping it supple. The use of a protective stratum between each printing is preferably avoided, the printed image being hardened by potash alum, chrome alum, or formalin, thoroughly washed to remove any traces of hardening solution and resensitized without drying the gelatin coating. Alternatively a gelatin solution to which a hardener has been added may be applied before resensitizing. Where a protective stratum is used, it may be formed by applying thinly, as by means of an aerograph, a 1 per cent solution of rubber in benzol followed by a coating of a celluloid solution in acetone. The final finished print is protected by a coating of rubber and celluloid.

In a process for catalytically steam reforming hydrocarbons in an externally heated tube, e.g. to make synthesis gas, the catalyst bed in the tube comprises a section at the inlet end of the tube and a section at the outlet end, and the first section has a lower surface area per unit volume of tube than the second section has. The catalyst in the second section, which may comprise 5 to 80% of the volume of the total bed, is of smaller particle size, e.g. 3 to 10 mm., than the first section, which may have a particle size in the range 5 to 20 mm., and/or may be made up of particles shaped to increase their surface area, being for example, hollow rings or cylinders, or star-shaped. In an example, the catalyst comprised (by weight) 22% NiO, 1% CrO 3 , 1% CuO on alumina silica supports and in experiments, particles of both 3mm. and 5mm. sizes were uniformly mixed in the bed for comparison with beds made up according to the invention.
