Title: Improvements in colour television systems
IPC: H04N9/04
Filed: 1969-03-26
Abstract: 1,210,615. Colour television. AMPEX CORP. 26 March, 1969 [29 March, 1968], No. 15879/69. Heading H4F. In a portable colour television camera system, the brightness signal is formed in accordance with a spectral characteristic M denoting a maximum sensitivity at wavelengths substantially shorter than those at maximum sensitivity according to the photooptic or Y luminance spectral characteristic, Fig. 3 (not shown), and is matrixed with further signals denoting sequentially at field rate red and blue content, to give red, blue, and green chrominance and "M" brightness signals. Use of the M characteristic rather than the Y curve is said to give greater sensitivity and a better signal to noise ratio. In a preferred embodiment, the maximum sensitivity according to the "M" characteristic coincides in wavelength with that of the normal green characteristic. A beam splitter 23 passes light through a trimming filter 29 to a pick-up tube 31 to give the "M" signal, and also to a chrominance pick-up tube 33 through a red and blue sectored filter 25 rotating to alternate the colour information at the field scanning rate. The signal from the tube 33 passes directly, and also indirectly through a network delaying the signal for one field duration, to an electronic field switch 39 connected to a matrix processor 35 which gives the desired red, blue, green and "M" outputs, so that each red and blue signal is used both as an original signal and as a delayed signal displaced vertically by one line. The delay network comprises record, playback and erase heads, 43, 45, 47, respectively, disposed about a magnetic plated video disc 41, e.g. a twelve inch disc plated with nickel cobalt and rotated at 1800 r.p.m. The disc 41, filter 25, and switch 39 are synchronized with the vertical synchronizing signals. The tubes 31, 33 may be image orthicons or vidicons, but are preferably of the type using lead monoxide as a photoconductive material.

Abstract: 1462462 Extruding carbon compositions VEREINIGTE ALUMINIUM-WERKE AG 10 April 1974 [16 April 1973] 15963/74 Heading B5A A composition for forming a carbon product, is compacted into a continuous rod during movement through a tapering open-ended and peripherally closed die passage, defined by at least two segments each comprising a part of the periphery of the passage and which are connected together at resilient seals and are urged together by resilient means, and at least one of which is vibrated transversely of the axis of the passage to effect the compaction. The composition may comprise carbon and an electrode pitch binder, and air may be removed by vacuum from the composition in the passage, which may be heated. The vibrators may be electromagnetic, or mechanical, and of continuously variable frequency and/or amplitude, and the vibration may be directed at right angles, or at 60 to 90 degrees, to the axis of the passage. The passage may be of rectangular, square, or circular section, and may define ribs or grooves extending axially of the rod. In the Fig. 1 embodiment, a vertical rectangular passage 8 is defined by a pair of symmetrical segments 1, 2 between which are disposed seals 7 having rubber-like elasticity, the segments 1, 2 being suspended on leaf-springs 4 and vibrated, against compression springs 5, at right-angles to the axis of the passage. Alternatively, only one of the segments 1, 2, may be vibrated. The compacted material passes into a receiver 12, prior to sawing or shearing into length. The passage of the material may be effected from a hopper 9 merely by its weight, or by a ram 13, and additional material may be introduced into the hopper 9 by a charging screw. The passage may alternatively be conical, to compact a circular section rod, and be defined by three segments each magnetically vibrated by a serial connection to one phase of a threephase current. In the Fig. 3 embodiment (not shown) a pair of segments are each vibrated against spring loading by a vibrator comprising a pair of counter rotating unbalanced weights. The material may alternatively pass through the passage horizontally under the thrust of a worm conveyer, and assisted by vibration at an acute angle to the axis of the passage.

Abstract: 1,237,629. Artificial eyes. CESKOSLOVENSKA AKADEMIE VED. 27 March, 1969 [5 April, 1968], No. 16038/69. Heading A5R. [Also in Division G2] A method of forming colour effects in hyrogel contact lenses and ophthalmic protheses comprises cementing a coloured, water insoluble pattern between a substantially finished transparent hydrogel contact lens or a similar front part of an artificial eye and a thin covering hydrogel layer of uniform thickness by polymerizing therebetween a monomer mixture capable of forming the same or similar hydrogel. The layer may be preformed or formed in situ by polymerization of the monomer mixture. The pattern may be a transfer or may be drawn using the dry needle method or printed on either the layer or on the concave surface of the lens. The layer may be formed on a smooth plane or spherical pad. If the layer is planar the lens may be rendered planar prior to cementing by being at least partly dehydrated and pressed onto a smooth surface heated above the glass transition temperature of the lens. After cementing the lens is returned to substantially its original shape by immersion in water or a physiologic solution. The lens may be dehydrated by superheated steam immersion in warm concentrated salt solutions, aqueous glycerol or ethylene glycol solutions or evaporation through a plastics film and may be plasticized with water, glycerol or ethylene glycol. The curvature of the final lens may be adjusted by the addition of a physiologically innocuous solvent such as glycerol diacetate to the monomer mixture. The lens may be formed by polymerisation casting or by turning from a hard, non-molten block or blank, the lens being subsequently swollen. Examples of various hydrogels and monomer mixtures are given.
