Title: Improvements relating to modified polymethylenes
IPC: C08F8/32
Filed: 1963-04-23
Abstract: Olefin polymers which have substantially wholly a backbone chain of polymethylene units contain side chain radicals of structure <FORM:1006589/C3/1> wherein: C is an integer from 0 to 10; b is 0 or 1; R and R1 are the same or different and are hydrogen or lower alkyl radicals; U, V, W, X, and Y are the same or different and are primary amino, secondary amino, tertiary amino, quaternary ammonium or acyano groups, chlorine, bromine, iodine or hydrogen atoms, with the proviso that at least one of U, V, W, Y and Y are amino, ammonium or cyano. The nitrogen-containing polymer is preferably made by reacting the corresponding halogen-containing polymer with the compounds containing the nitrogen.  The halogen-containing polymer may be made either (i) by copolymerizing ethylene with a compound of formula <FORM:1006589/C3/2> wherein the Q radicals are the same or different and are lower alkyl groups or hydrogen, chlorine, bromine or iodine atoms, with the proviso that at least one Q radical must be a halogen atom; or (ii) by halogenating or hydrohalogenating a copolymer of ethylene and a non-conjugated diene.  In the examples an ethylene/5-bromo-1-pentene/1,4-hexadien copolymer is reacted with cyclohexylamine, ethanolamine, glycine, ammonia, N-)n-butyl)-p-aminophenol, 2-aminopyridine, morpholine and morpholine followed by ethyl bromide, also an ethylene (5,6-dibromo-1-hexene copolymer is reacted with diethanolamine and morpholine.

Abstract: 995,722. Making moulds. ROLLS-ROYCE Ltd. April 17, 1964, No. 16104/64. Heading B5A. [Also in Division B3] A shell mould 10 is formed, e.g. by dipping, on a wax pattern 13 formed on the head 14 of a handle 15 made of electrically conducting material. To remove the handle a heating coil 22 is located round the shell mould and is supplied with alternating current at a frequency of 10-450 kilocycles per second so that the head 14 is heated 14 and melts the immediately surrounding wax allowing the handle to fall from or be removed from the mould. The method could be used to remove an electrically conductive member from non-conductive material in which it is embedded.

Title: Improvements in or relating to electrical counter circuits
IPC: H03K25/00
Filed: 1945-06-29
Abstract: 596,459. Frequency modulation; valve circuits. WHITE. E. L. C. June 29, 1945, No. 16571. [Class 40 (v)] [Also in Group XXXVI] A circuit arrangement for counting electric oscillations fed to a thermionic valve comprises means for setting up across an output impedance voltages of amplitude variable with frequency and separate means for limiting the amplitude of the voltages before applying them to the counter circuit. Frequency modulated oscillations are applied to amplifier 1, Fig. 1, the output of which is fed through a condenser 7 to a counter circuit comprising two oppositely connected diodes 8 and 9. A voltage proportional to the frequency appears across a resistance 10 in the cathode circuit of diode 9. The amplitude of the voltages fed to the counter circuit is made more nearly constant over a wide frequency band by two oppositely connected diodes 13, 14 which are arranged between the anode of amplifier 1 and tapping points on the H.T. supply 6. The tapping points are chosen to limit the voltage fed to condenser 7 to a value not greater than that obtained at the highest operating frequency. In a modification (Fig. 2, not shown), an inductance, in series with a blocking condenser, is connected across the amplifier valve and arranged to resonate with the capacities in the circuit at the mean applied frequency. In a further modification (Fig. 3, not shown), the anode load resistance of the amplifier valve is replaced by an inductance connected to a tapping point on the H.T. supply midway between the potentials applied to the limiting diodes. In another embodiment, Fig. 4, the incoming oscillations are fed to two valves 1, 17 in pushpull. The valves have a high common cathode impedance and their anodes are connected by an inductance 15, which is centre-tapped to the H.T. supply. The inductance 15 is chosen so as to resonate at the mean applied frequency with the capacities present in the circuit. The output of the counter diodes 8, 9 is applied through filter network 26, 27, 28 to the cathode circuits of amplifiers 22, 23, from the anodes of which a push-pull output is obtained. The parallel-tuned circuit formed by the inductance 15 and the stray capacities of the circuit may be shunted by a damped series-tuned circuit having the same resonant frequency to broaden the response. Specification 471,731 is referred to.

Abstract: 1,221,325. Photo-polymerization process for the production of dye images. FUJI SHASHIN FILM K.K. April 5, 1968 [April 6, 1967J, No.16629/68. Heading G2C. Dye images are produced by imagewise exposing a negative or positive silver halide emulsion to electromagnetic waves or particle rays, contacting the exposed emulsion with a reducing agent which is resorcinol or m-aminophenol or a derivative of either or a naphthol containing either two hydroxyl groups or one hydroxyl group and one amino group or one amido group in the 1, 6; 1, 8 or 2, 7 positions, and with a vinyl or vinylidene monomer or a maleate containing an acid or basic group thus polymerizing the monomer in the areas corresponding to the latent silver image and dyeing with a dye having an acidity or basicity opposite to that of the polymer. The silver image which is produced on polymerization may be bleached out before or after dyeing the polymer image. The dye image may be transferred to a receptor sheet by the conventional spirit duplicating process. Specified monomers with acid groups are acrylic, methacrylic and maleic acid and their ammonium, alkali metal and alkaline earth salts and vinyl sulphonic acid and its ammonium and alkali metal salts. Specified monomers with basic groups are vinyl pyridines, N, N-dialkylaminoethyl-acrylates and -methacrylates and vinyl monomers containing quaternary ammonium salts. Monomers which do not contain such groups may be added to the monomer mixture. In the examples, various negative and positive silver halide emulsions are imagewise exposed and contacted with a solution containing alkali, reducing agent and monomer. The silver image is then fixed and the material immersed in the appropriate dye and acid (if a basic dye is used) or a buffer solution ofpH 5À0 (if an acid dye is used). The silver image may be removed by Farmer's reducer and the dye image remaining may be transferred to a receptor sheet. The processing solution preferably contains a sulphite ion. Any dye in the unpolymerized areas is removed by washing with acetic acid or the unpolymerized areas may be removed by washing.

Abstract: 334,243. Goldsmith, J. N., and Spicers, Ltd. May 30, 1929. Colour photography.-In the production of multicolour screens upon a support of celluloid or a cellulose ester such as cellulose acetate or nitro-cellulose, a greasy resist containing a dye is applied, as by printing, to the surface of a film in a series of lines or a geometrical pattern, and the dye migrates from the resist into the surface of the film so that, after removal of the resist as by a solvent, a coloured series of lines or pattern remains on the film. The resist may be a greasy ink, or thickened linseed or other vegetable oil used with oil-soluble dyes, such as oil orange, or oil red, and it may include a solvent for the dye, such as acetic acid, which enables the dye to penetrate into the surface of the film. Before the resist is removed from the film, the interspaces between the lines, which are not protected by the resist, may be coloured with a colour different from that applied in the resist, so that when this is removed, a two-colour screen remains.
