Title: Improvements relating to materials and processes for photo-lithographic printing
IPC: G03F7/038
Filed: 1950-05-12
Abstract: 676,665. Photographic layers ; photolithographic printing. KALLE & CO. AKT.-GES. May 12, 1950 [May 14, 1949], No. 11963/50. Class 98 (ii). A foil or plate as of aluminium, zinc, plastic, glass, paper or textile fabric is provided with a layer of a polymer of acrylic acid amide or a homologue thereof such as polymethacrylic acid amide or a derivative substituted as with alkyl groups in the amino group or an interpolymer of any of the amides, as with vinyl acetate, or a mixture of any of these with other artificial colloids: the layer being sensitized as with a chromate, diazo compound or azide. Portions of the layer exposed under a transparency harden, and the remainder can be washed away with water, aqueous alcohol or alcohol to yield a product which can be used as a planographic, offset or intaglio printing plate. In example 1, an aqueous solution of the polymerization product of N-mono or di-methyl acrylic acid amide sensitized with the condensation product of p-diazo-diphenylamine and formaldehyde is applied to a support such as aluminium foil, exposed under a negative and washed with water to leave a positive which may be dyed with methylene blue to provide a positive blue image. Similar procedure is described in example 2 except that exposure is effected under a positive, the exposed foil is washed and dried and the resulting negative colloidal image is developed to become a positive printing plate by coating the negative with alcoholic lacquer, inking with greasy printing ink and removing the polymer which was hardened in the exposure and the lacquer thereupon. Example 3 specifies a zinc plate coated with aqueous poly-N- diethylacrylic acid amide which is sensitized with ammonium bichromate, exposed under a positive, washed, and developed as in example 2. In example 4 a foil of vinyl chloride-acetate copolymer is coated with polyacrylic acid amide sensitized with the sodium salt of 4 : 4<SP>1</SP>-diazidostilbene-2 : 21-disulphonic acid, exposed under a negative, washed and treated with Sirius Light Blue G to give a blue positive. Examples 5-7 describe aluminium foils coated with acrylic acid amide copolymers with the sensitizer of example 4, and these are treated generally as in example 2 to provide positive printing plates suitable for flat and offset printing. Specification 418,011 is referred to.

Abstract: 402,665. Signs. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London. -(Assignees of Patent-Treuhand-Ges. fur Elektrische Gluhlampen ; 11, Ehrenbergstrasse, Berlin.) April 25, 1933, No. 12085. Convention date, April 25, 1932. [Class 3 (ii).] In a luminous electric discharge tube of the kind shaped to form a letter or other symbol or sign, the subsidiary parts of the tube, which are intended to be concealed and which connect together or to electrode chambers the main parts of the tube displayed in the sign, are formed of smaller diameter than the main parts of the tube. Fig. 1 shows gas-filled discharge tubes having main parts 1, adapted to form letters of a sign, which are connected together and to electrode chambers 4 by subsidiary parts 2, 3 respectively. The subsidiary parts are of reduced diameter and are bent back to the rear of the sign. To provide for even illumination of the sign, the ends of the subsidiary parts may be formed as nozzles 6 which enter the main parts of the tube in the manner shown in Fig. 3, and the main parts may be of opalescent or frosted glass or may be coated with a light diffusing paint. The subsidiary portions of the tube may be concealed in a casing 5, Fig. 3, which forms a backing for the sign. When no backing is provided, the subsidiary parts 2 may be coated with opaque material, the subsidiary portions 3 being concealed in longitudinally split sleeves 8, Fig. 4, which are formed with fingers 11 for gripping and supporting the main parts 1. The sleeve 8 is connected to a casing 13 which surrounds the electrode chamber 4 and which is secured to a support 15. A rubber ring 16 may space the electrode chamber 4 from the casing 13.

Abstract: 662,675. Cathode-ray oscillographs; condensers. MORRIS MOTORS, Ltd. May 3, 1950 [May 6, 1949], No. 12125/49. Class 37. An electronic time base generator comprises a thermionic valve oscillator the frequency of which is varied cyclically by a variable condenser one component of which is rotated continuously by the signal-producing unit under investigation and modulates the amplitude of the output of a resonant tuned circuit, the amplitude-modulated output being passed to a linear detector, amplified, and then fed to one pair of the deflecting plates or coils of a cathode-ray tube. In the arrangement shown in Fig. 1, the circuit of the time base generator includes a pentode valve electron-coupled oscillator 1, a detector valve 2, and an amplifier connected at 3. A mechanically-driven condenser 4 is connected across either the tuned control grid 5 of the oscillator, as shown, or its tuned anode or tuned anode secondary. The resulting amplitude-modulated output of the resonant tuned circuit is applied to the grid 8 of the detector 2 and, after amplification, is fed to the X-plates of a cathode-ray tube to form the time trace. The condenser 4 may be of any form shown in Figs. 4 to 9A. In each case a T-shaped radial vane 9, mounted on a spindle 10 which is rigidly coupled to the driving shaft of the unit under test, is disposed within a stationary tubular component 11 ... 16.

Abstract: 1,034,673. Cheddar-type cheese production. COMMONWEALTH SCIENTIFIC & INDUSTRIAL RESEARCH ORGANIZATION. March 27, 1963 [March 30, 1962], No. 12186/63. Heading A2B. The production of cheese of Cheddar and Cheshire type involves fusion and firming of the milkcurd by gravity and enhancing the uniformity of such conversion by inverting the curd during the operation. With the apparatus of the drawings (Figs. 1A, 1B, 1C and 2) curds deposited in vat 1  with a retractable flow 10 are stirred continuously by stirrers 85 and the whey is allowed to drain away through perforations in the walls 9. After this initial firming of the curd, floor 10 is moved to position 15 (Fig. 1C) and the curd allowed to fall into a succession of compartments of which the divisions are slats 21 carried on rails 26 on the upper run of an endless conveyer 19 and of which the sides are belts 27. Curd is evenly distributed in the succession of compartments by a travelling mesh roller system 47. The curd is inverted on the opening of the slats 21 as they turn for conveyance on the lower run of the endless conveyer 19, and the curd also assumes the configuration 80a (Fig. 14), which assistes in further firming.

Filed: 1954-04-30
Abstract: Liquid polyepoxide resins prepared from dihydric phenols and more epichlorhydrin and having at least two epoxide groups per molecule and more epoxide groups than hydroxyl groups and free from functional groups other than hydroxyl are cured by addition of FriedelCrafts catalysts preferably in the presence of diluents neutral to the catalyst and polyepoxide, e.g. dibutyl phthalate, chlorinated polyphenols.  There also may be present as diluents compounds which are polymerized by the catalyst, e.g. phenyl glycidylether, allyl glycidylether, epichlorhydrin, turpentine, styrene oxide.  Suitable catalysts are boron trifluoride complexes with ether, water, acetic acid and butanol; stannic chloride, antimony pentachloride.  The catalyst and resin may be applied from jets of a spray gun on to the surfaces to be united, e.g. glass cloth or laminates.  In examples: (1) "Technical TPG" was hardened by addition of antimony pentachloride in butyl acetate; (3) the resin as in (1) mixed with a 10 per cent solution of boron fluoride etherate in methyl ethyl ketone and aluminium powder was poured into a mould and hardened in 3 minutes without shrinking; (5) "Technical DPG" containing 25 per cent epichlorhydrin was sprayed from one jet of a twin jet gun and a 10 per cent solution of boron fluoride/butanol in butanol was sprayed from the secondary jet to give a 4 per cent concentration of catalyst.  The sprayed panels were coated with thick films of high gloss which hardened in 8 minutes.
