Title: Improvements in or relating to the treatment of cellulose derivatives
IPC: C08B3/22

Abstract: The cellulose derivative used in the manufacture of compound transparent sheets as described in the Parent Specification is treated in the solid form with a bleaching agent such as sodium or potassium chromate, dichromate, permanganate, hypochloride. calcium hypochlorite, hydrogen peroxide, nitric acid, chlorine, to prevent discolouration.  In examples given 10 lbs. of cellulose acetate in powder, filament &c. form are mixed with 100 lbs. of water and treated with one of the bleaching agents specified above and removed by filtration and then washed and dried and if desired dissolved and filtered to remove impurities.  Plasticizers or synthetic resins may be used with the cellulose derivative solutions in making cellulose derivative sheets for laminated glass and a stabilizer such as urea and pigments or dyes may be added.  Also synthetic resins such as those described in Specifications 296,675, 299,065, 299,066, [all in Class 2 (iii), Dyes &c.], or 347,646 may be used as adhesives.

Title: Process for De-odourising and De-colourising Cocoa Butter.
IPC: C11B3/14
Filed: 1918-02-09
Abstract: 122,512. Co-operative Wholesale Society, Martin, G., and Brizell, W. J. Feb. 9, 1918. Fats, purifying.-Cocoa butter is decolorized and deodorized by treatment with superheated steam at a temperature of from 140 to 210‹ C., preferably nearer the lower limit. The cocoa butter is melted in a vessel A provided with stirrers 2 and a heating-coil 5, and passes by a pipe 8 warmed by a steampipe 9 to a steam-jacketed vessel B containing a perforated pipe 24 by which the superheated steam can be introduced. The steam, along with the impurities, is condensed in coils 14 and passes to an exhausted tank E. The purified cocoa butter passes by a pipe 29 to a tank C. In a modification, the steam is produced by heating the butter in contact with a quantity of potatoes. The potatoes assist in clarifying the butter, a little animal charcoal being added if necessary, and the butter is strained away from the potatoes in running off.

Title: Improvements in or relating to electron discharge devices
IPC: H04N5/74
Filed: 1936-01-27
Abstract: 469,558. Discharge apparatus. HARMAN, M. Jan. 27, 1936, No. 2511. Convention date, Jan. 25, 1935. [Class 39 (i)] An electron-discharge device comprises a layer of small particles of opaque or semiopaque material, the layer being adapted to be rendered translucent or transparent under the action of an impinging beam of electrons. In the device shown an evacuated glass vessel is closed at one end by a flat glass plate 1. A thin membrane 4 is stretched parallel to plate 1 at a short distance from it, and the space between is filled with a suspension of smoke particles which are maintained positively charged by a ring anode 3. The membrane 4 is pervious to electrons but not to smoke particles. The cathode-ray beam 7 impinging on an element of the layer charges the particles negatively, so causing them to be attracted to the neighbouring positively charged particles. The transparency of this point is thereby temporarily increased to an extent dependent on the intensity of the beam 7. The kinetic action of the beam produces a similar effect. In a television receiver, light from a source 6 is projected on the layer and emerges modulated by the action of the scanning beam. If the plate 1 is of ground glass an image will be made visible thereon. The method mav also be used for scanning an object to be transmitted. The device is preferably operated with the layer in a horizontal position, to maintain the suspension of the particles.

Divided on 409,737. [Class 40) v).] In a superheterodyne receiver, the incoming signals are applied to a grid M controlling one electron path adjusted to operate without rectification and in series with a second electron path controlled by a grid 0 to which the local oscillations are applied. The grid O is coupled to the anode A over a condenser R, to generate oscillations at a frequency determined by the tuned circuit LC and the voltage on grid 0 is so high that ,oscillations of the form shown in Fig. 2 are produced, interrupting the incoming signals to produce the intermediate frequency across inductance Z. By operating the first electron path without rectification, interference due to two carrier frequencies beating at the intermediate frequency is eliminated. Specifications 172,350, 301,498, 312,698, 313,414, [all in Class 40 (v)], are referred to. According to the Specification as open to inspection under Sect. 91, the oscillations may be generated by a separate valve. This subjectmatter does not appear in the Specification as accepted.

Abstract: 867,430. Phase-sensitive circuits. BENDIX CORPORATION. Jan. 28, 1959 [Feb. 4, 1958], No. 3088/59. Class 38 (4) In order to eliminate from an A.C. signal unwanted quadrature components the signal is gated by a reference signal so that only the peaks of the desired component are passed. Current between the A.C. signal input 23 and the output 37 is gated by diodes 31, 33 which are rendered non-conducting by bias from the unsmoothed output of a full-wave rectifier 9, 11 supplied by the reference source 1 which is in quadrature with the desired signal. A capacitor 17 is charged through a further diode 15 to provide a D.C. bias, part of which is tapped off a potential divider 19, 21 to oppose the pulsating bias so that the gating diodes 31, 33 can conduct for a short period each time the pulsating bias approaches zero, which corresponds to the maxima of the desired signal component and the minima of the quadrature component. A tuned circuit 39, 45 rejects the harmonic content of the current pulses.

Abstract: 1362601 Electrolytically recovering copper COPPER PROCESS Ltd 24 Jan 1972 [25 Jan 1971] 3301/72 Heading C7B Copper is recovered from Cu ore (or concentrate) by leaching the ore with a solution comprising a soluble cupric salt (e.g. chloride) and a solubilizing agent for cuprous Cu (e.g. NaCl, KF, LiBr or other alkali metal halide, or CaCl 2 , HCl, HBr or HI) to form a soluble cuprous complex (e.g. sodium cuprous chloride), separating the remaining solids from the resulting leach liquid, electrolytically reducing one portion of the leach liquid to precipitate Cu metal which is recovered and electrolytically oxidizing another portion of the leach liquid to produce a solution comprising cupric salt, combining the reduced and oxidized solutions and recycling as further leaching solution. Oxygen free conditions are maintained throughout. The S.G. of the reduced solution is lesser and of the oxidized solution is greater than that of the leach liquid, so that electrolysis is preferably effected in a cell having alternating anode and cathode compartments separated by ion permeable membranes, e.g. of woven asbestos or fibreglass, equal halves of the leach liquid being fed respectively to the top of the anode compartments and bottom of the cathode compartments, and the oxidized and reduced solutions being collected respectively from the bottom and top of such compartments. The electrodes may be of carbon e.g. graphite, Cu, Cu-Si or Al 2 O 3 . The Cu ore may also contain Ag with or without Mn, Sb, Bi, Fe, Pb, Zn, Co, Ni, Mo, Ti, Cr and/or Hg, which are at least partly removed from the resulting leach liquid prior to electrolysis by precipitation of their oxides with CaO; at least part of the Ag may be precipitated from solution by metal interchange with Cu metal subsequent to CaO precipitation. The ore may be pulverized during and/or prior to leaching. Remaining solids may be washed with a ferrous chloride solution and after separation at least part of the Cu in the separated wash solution may be precipitated by metal interchange with Fe metal. Any sulphur in the washed remaining ore may be removed by floatation. The solvent for the cupric salt and solubilizing agent may be aqueous or a C 1 -C 5  alcohol, phenol, organic acid. The cathode compartments may be provided with Cu powder collecting chambers containing an inert liquid.
