Filed: 1960-03-10
Abstract: 917,068. Electric selective signalling systems. COMPAGNIE DES MACHINES BULL. March 10, 1960 [March 17, 1959], No. 8545/60. Class 40 (1). [Also in Group XVI] In a printing-machine operated from pulses record cards or tapes (see Group XVI), electrical circuits and " mechanical nought-printing devices " are provided whereby, with the aid of manually positionable members, the automatic printing of the noughts may be controlled or prevented when there is systematic control in chosen printing columns. The electric circuits can be set either manually or automatically by means of relays. With this arrangement manual positioning of control members is avoided, since the arrangements particular to a particular working programme may be automatically fixed by the positioning of a control panel provided with the appropriate connections. As shown in Fig. 4, a record card CR is sensed in columns CL1 ... CL120 and enables the printing of noughts whether or not these noughts are punched in the record cards. Specification 907,479 is referred to.
Patent GB-1073851-A (GB)
Title: Vulcanisable rubber mixtures
Inventor: FREDERICK RUPERT
IPC: C08L21/00
Filed: 1965-02-27
Abstract: Vulcanizable compositions comprise rubber, a free sulphur vulcanizing system and a rubber reinforcing composition comprising a formaldehyde donor and a reactive phenolic composition comprising a resin obtained by reacting phenol with sulphur or a sulphur chloride, the proportion of phenol/sulphur resin being 1 to 15% by weight of the rubber.  The rubber may be natural rubber, polyisoprene, polybutadiene, polychloroprene, butadiene/styrene copolymer, butadiene/acrylonitrile copolymer, isobutylene/isoprene copolymer or ethylene/propylene/diene terpolymer.  The formaldehyde donor may be hexamethylene tetramine, paraform, anhydroformaldehyde aniline resoles or melamine/formaldehyde resins.  The reactive phenolic composition is essentially not heat advancing or self hardening, but reacts with the formaldehyde donor to form a thermoset product. If the phenol/sulphur resin does not so react a novolak must also be added, or the resin co-condensed through formaldehyde with a trifunctional phenol.  The resin may be prepared by reacting phenols containing at least two free o or p positions with sulphur or a sulphur chloride under alkaline conditions.  The reactive phenolic compositions preferably also contain a novolak resin.  In examples styrene/butadiene, acrylonitrile/ butadiene and natural rubbers are vulcanized with reactive phenolic compositions comprising hexamethylene tetramine and (1) a phenol/sulphur resin, (2) a cresol/sulphur resin, (3) a phenol/sulphur resin and a cashew nut shell oil modified phenolic novolak, (4) a cresol/sulphur resin and a phenol/formaldehyde novolak, (5) a phenol/sulphur resin reacted with formaldehyde, (6) a phenol/sulphur resin reacted with formaldehyde and modified with partially polymerized cashew nut shell oil, (7) a cyclopentenyl phenol/sulphur resin reacted with formaldehyde, and then with phenol and formaldehyde, and (8) a resorcinol/sulphur resin.

Title: Improvements in and relating to surface coatings
Inventor: CHATFIELD HERBERT WALTER
IPC: B05D7/02
Filed: 1958-03-12
Abstract: A lacquer comprising an unsaturated polyester and an ethylenically unsaturated monomer is applied to a surface to be coated, and a protective coating of a film-forming cellulose derivative in solution in a volatile solvent is applied over the lacquer coat within a period of about 2 hours after the application of the lacquer.  The cellulose derivative may be an ester or ether, e.g. cellulose nitrate, cellulose acetate, cellulose acetate butyrate or ethyl cellulose.  Curing of the lacquer coating may be followed by removal of the protective coating, and polishing.  In examples, an unsaturated polyester is prepared from propylene glycol, maleic anhydride and phthalic anhydride, and mixed with styrene monomer containing hydroquinone as a stabilizer.  For use, the resulting solution is mixed with solutions of cobalt naphthenate and methyl ethyl ketone peroxide, and applied to a suitable surface by spraying. After an interval of 30 minutes, a solution of nitrocellulose in a mixture of methylated spirits and ethyl acetate, or of cellulose acetate in acetone, is sprayed on the coating thus formed.  After 12 hours, the cellulose derivative films are removed by rubbing down with fine emery paper, using white spirit and paraffin wax as a lubricant.  A hard, glossy film is obtained after polishing.

Title: Improvements in or relating to colour television transmitting systems
Inventor: BILLIN JAMES JOHN
IPC: H04N11/12
Filed: 1956-03-22
Abstract: 852,512. Television. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 18, 1957 [March 22, 1956], No. 8910/56. Class 40(3). In a colour television transmission system in which luminance signals 1 are transmitted with a full upper-side band and a vertigial lower sideband together with chrominance signals comprising a narrow double side-band modulation 3 and, in quadrature therewith, a second modulation 4 having a full upper side-band and a vestigial lower side-band, the upper frequencies of the luminance signals 2 (i.e. those between 4À75 and 7 mc/s. are transmitted, as shown, on the vestigial side of the luminance carrier. By employing this arrangement instead of extending the upper side-band of the luminance signals 1 to 7 mc/s. increased definition is obtained without the need for changing the spacing between the vision carrier O mc/s. and the sound carrier 5.5 mc/s. which would present inter-carrier sound operation in co-operating receivers. In such a receiver (Fig. 2) a chrominance trap 9 is arranged to suppress the chrominance signals 3, 4 so that the luminance channel receives only the luminance signals 1 and 2. Such a trap would also be provided in monochrome receivers designed to receive signals as described in connection with Fig. 1 and would receive normal definition signals on one side-band and higher definition signals on the other side-band.
