Abstract: 1,259,196. Colour television. RANK ORGANISATION Ltd. 27 Feb., 1970 [28 Feb., 1969], No. 10868/69. Heading H4F. Colour television image formation is recorded on a monochrome recording medium, e.g. a cine film, by recording separately in each of the image frames, Figs. 3 and 4, luminance information and two chrominance information components (e.g. the U and V colour difference signals in the PAL system), the luminance information occupying more area on the recording medium than the chrominance information whose separate components are recorded sequentially with respect to the length of the recording medium each occupying half the area prescribed to the chrominance information. Scanning of the film is preferably effected by one flying spot scanner having a plurality of rasters and deflecting arrangements (although two may be used) and two photo-electric cells, the scanning beam for the chrominance information being jumped by half a frame after each alternate scan, Fig. 4. The sequential U and V signals are rendered simultaneous by means of a one-line scan delay and matrixed with the luminance signal to obtain for example the red, green and blue signals. Two tracks may be recorded on the film, each track having its own sound channel but both tracks using the same synchronizing marks, Fig. 1 (not shown). Instead of the above film recording, holographic or thermoplastic recording techniques may be used.

Abstract: 1,266,402. Coated products. WESTINGHOUSE ELECTRIC CORP. 18 March, 1969, No. 14091/69. Heading B2E. [Also in Division H1] A plurality of spaced conductors on a resin film are formed by etching a metal foil coated with a resin film, removing the etching resist used to define the conductors, and etching the metal conductors to round the sharp edges thereof. Copper foil from roll 10 is kiss coated on one side with a resin film in bath 11 to the required thickness, dried in tower 14 and then applied with parallel strips of paraffin wax or thermoplastic resin etching resist from extruder head 15 on the other side. After etching in tank 16 the resist is removed in tank 17 and after washing in tank 18 the conductors are subjected to a further etching process in tank 19 to round off the sharp edges of the conductors, Fig. 4. A resin coating is deposited on both sides of the composite by passing through tank 22. By performing the additional etching step sharp undercut edges of the metal conductors are removed so that they do not notch into the final resin coating. The conductors may be plated with a thin nickel flash prior to the final coating stage. The resin film kiss coated on the copper film may be a dimethyl acetamide solution of an aromatic polyamide-imide amic acid precursor formed by the reaction of pyromellitic dianhydride and 3,4'-diaminobenzanilide and the final resin coating a dimethyl acetamide, N-methylpyrrolidone and toluene solution of a soluble aromatic polyimide precursor derived from the reaction of the 4-acid chloride of trimellitic anhydride and p,p'- methylene bis(dianiline). Alternatively the final resin may be a dimethyl acetamide and xylene solution of an aromatic polyamic-acid precursor formed by the reaction of benzophenone tetracarboxylic dianhydride and 4,4'-diaminophenyl ether. The final resin coating solution may also be a dimethyl acetamide solution of precursor formed by the reaction of pyromellitic dianhydride and 4,4'-diaminophenyl ether and 3,4'-diaminobenzanilide. Reference has been directed by the Comptroller to Specification 1,104,100.

An ignition device comprises a tubular housing 10 on which a tubular, spring-loaded pushbutton 20 is guided non-rotatably. Pressure on the button 20 stresses a spring 23 engaging a hammer 18 until sloping edges 205 on a pair of longitudinal slots 203 in the button engage a transverse peg 19 on the hammer and displace the hammer angularly into alignment with the axis of the housing from the position shown in Fig. 1 in which the edge 181 of the hammer rests on the rim 103 of a transverse aperture (102) in the housing interconnecting a pair of longitudinal slots 101 wherein the ends of the peg 19 are slidable. Such displacement of the hammer allows it to be driven by spring 23 into engagement with a pin 17 on a piezoelectric assembly 13. On release of the push-button, further sloping edges 204 on the slots 203 engage the pin 19 and retract the hammer until they cause it to swing out of alignment with the housing and the edge 181 re-engages the rim 103.

A closed holder 15 containing one or more substances to be introduced into the envelope 6 of a discharge tube or lamp is opened by passing current through a heating element 14 located outside the holder 15 in heat-conducting contact with a portion of a wall thereof and connected to the ends of an electric conductor 12 into which current is induced by a coil 17 placed outside the envelope. In the lamp shown the conductor 12 is an open iron ring surrounding an electrode 11 and supported from the pinch 9 by a wire 13. The glass holder 15 contains mercury and argon at a pressure of about 1 atmosphere. The conductor 12 may be resilient strip (Figs. 1 and 2, not shown) which retains the holder 15 against the heating element 14. Alternatively the strip may have two loops pressed from it (Figs. 5 and 6, not shown) to support each half of the holder 15, so that if the holder breaks into two halves on opening, each half is still attached to the strip. As a further alternative (Figs. 7 and 8, not shown) a copper clad wire may be sealed along the axis of the holder to maintain a connection between the two broken halves. The holder 15 may contain a gettering substance.

Abstract: 1296387 Separating gaseous mixtures STAL REFRIGERATION AB 1 Dec 1969 [11 March 1969] 58567/69 Heading F4P In a process for removing water and separating a particular constituent from a wet gaseous mixture, water capour is removed from the mixture by condensing and solidifying before the constituent is separated. The wet gaseous mixture in tank 1 is passed via valve 2 through the sheet space of a heat exchanger 3 containing a tube stack 5 filled with ice from a previous cycle. Water vapour in the mixture is partially condensed and run off at valve 7 whilst the ice is melted and run off at valve 6. The gas passes from exchanger 3, via valves 8 and 9 into the tube stack 10 in a second exchanger 11, wherein it is cooled in heat exchange with gas from which the water and particular constituent has been removed thus solidifying the water vapour. The gas then passes via a non-return valve 12 to condenser 4 wherein the particular constituent is condensed and collected in tank 14; the condenser is cooled by a refrigeration machine 13. The residual gas passes via valve 2 back to heat exchanger 11 and then via valve 8 to a reservoir 15. When a predetermined amount of ice collects in tube stack 10 valves 2,8 and 9 are reversed and water vapour is condensed in exchanger 11 and frozen out in tube stack 5.
