Patent GB-1091521-A (GB)
Title: Esters of polymers
Inventor: OSMOND DESMOND WILFRID JOHN
IPC: C08F8/00
Filed: 1963-06-04
Abstract: Novel polymeric compounds comprise esters of a long chain unsaturated monocarboxylic acid and a polyol of which one hydroxyl group per molecule is esterified with polymerized methacrylic or itaconic acid, the ester link between the polyol and polymerized acid having been formed before the ester link between the polyol and long chain acid. The polymerized acid may be a homopolymer or a copolymer of the acid with one or more monomers such as styrene, vinyl toluene, vinyl ethers, acrylonitrile, methacrylonitrile, acrylamide, methacrylamide, an ester of an a -alkyl substituted unsaturated acid and, in a minor proportion, an acrylate ester. The polyols used are aliphatic compounds, e.g. ethylene glycol, propylene glycol, butylene glycol, glycerol, pentaerythritol, hexanetriol, di- or tri-ethylene glycol and tri-methylolethane or -propane.  The polyol mono-ester is preferably formed by esterifying the polyol with monomeric methacrylic or itaconic acid and then polymerizing the product; it may also be formed, however, by hydroxyalkylating a preformed polymer or copolymer of methacrylic or itaconic acid with an alkylene oxide such as ethylene, propylene or butylene oxide.  As the long chain acid component of the final esters, there are specified tall oil, soya bean oil, linseed oil, tung oil, oiticica oil and dehydrated castor oil fatty acids.  Part of the unsaturated long chain acid may be replaced by a saturated, carboxylic acid containing at least 6 carbon atoms, e.g. stearic acid or coconut oil acid, an aromatic carboxylic acid, e.g. benzoic acid, or a carboxylic acid anhydride, e.g. maleic or phthalic anhydride.  Also, part of the polymerized methacrylic or itaconic acid may be esterified with a monohydric alcohol, e.g. methanol, 2-ethylhexanol, lauryl alcohol and synthetic C8-C12 alcohols.  In examples, hydroxyalkyl methacrylates are copolymerized with styrene, methyl methacrylate or methyl methacrylate/lauryl methacrylate in mixtures of polar and non-polar solvents using benzoyl peroxide or azodiisobutyronitrile as catalyst, and the product is then esterified with appropriate fatty acid while distilling off some of the solvent.  Solutions of the polymer esters are suitable for coating and form hard films on air-drying; for such applications additives may be included, e.g. lead or cobalt naphthenate driers and titanium dioxide pigment.

Title: Improvements in or relating to apparatus for making mosaicscreens for colour photography
IPC: G03C7/10
Filed: 1928-08-04
Abstract: 322,454. Wade, H., (Compagnie d'Exploitation des ProcÚdÚs de Photographie en Couleurs L. Dufay, [known as Versicolor Dufay]. Aug. 4, 1928. Colour photography, multicolour screens for.- A machine is described for treating a long strip of dyed sheet material, e.g. a. cellulose acetate film, having a resist pattern printed thereon for the production of two-colour or multi-colour screens of the kind described in Specifications 217,557 and 322,432. The film or strip 14, Fig. 1, passes first over a decolourizing trough 15, for decolourizing the parts not protected by the resist. This trough is mounted on adjustable arms 16 so that the film is not immersed in the trough; and the rollers 20 under which the film passes are adjustable longitudinally so that the extent of the decolourizing can be regulated. This feature is more especially for providing a longer treatment during a second decolourizing treatment for making multi-colour screens. From the trough 15 the strip passes under a roller 21 upon which it receives dye from an ebonite roller 22. The latter dips into a dye trough 23 and is adjusted so that it rotates in proximity to, but not in contact with, the strip. It may rotate at a speed greater than the passing speed of the strip, or it may be rotated in the opposite direction. From the dye roller the strip passes under a larger roller 24 and is washed by jets from pipes 26. The strip then passes over absorbent rollers 29 in a zig-zag path to dry it, and passes thence through one or more troughs 31 containing a solvent for the resist and also provided with driven wiping rollers 44. It may then pass through a degreasing trough 32, also fitted with driven wiping rollers 44a acting on both sides of the strip, and then through a rinsing trough 33 which has no wiping rollers. Thereafter the strip passes over a staggered series of absorbent rollers, and then over heated drums to a storage reel. The troughs 31, 32, 33 are mounted on a vertically-adjustable, platform 34, and squeeze rollers 40 are fitted in conjunction with the driven rollers 38 over which the strip passes. In the machine, all rollers over which that side of the strip which carries the resist material passes preferably comprise two conical roller elements at the ends, so that only the edge of the strip is engaged.

Title: Improvements in or relating to electrical oscillation generators
IPC: H03B5/18
Filed: 1939-01-10
Abstract: 523,648. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and RAMSAY, J. F. Jan 10, 1939, No. 23786. Divided out of 513,679. [Class 40 (v)] A remotely-tunable oscillator, suitable for control of a superheterodyne receiver, comprises a valve 1 with an oscillationmaintaining and frequency-determining circuit consisting of a length of high-frequency cable connected between the anode and control grid. A variable reactance TL is inserted in series at its midpoint, and the two halves of the cable run in parallel from the valve to the remote variablereactance tuning-device. If the reactance TL is an inductance, the frequency range extends from a low value to that value at which the total cable resonates at a half wavelength when TL is zero. If the reactance is a condenser, the frequency extends from this "halfwave" frequency when the condenser is large, to practically twice this value. If the variable reactance is a condenser in series with a loading coil, the frequency range extends from a little above zero to twice the "half-wave" frequency. Several valves in cascade may be employed, the cable extending from the output of one valve to the input of a preceding valve. Feedback may be reduced by tapping down the anode or grid connections to the cable. Higherorder modes of oscillation may be obtained as described in Specification 493,862. Specification 513,679 also is referred to.
