Title: Method of recording information
Inventor: NEALE DENIS MANKTELOW
IPC: H04N5/84
Filed: 1967-04-17
Abstract: 1,216,835. Recording colour television. COLUMBIA BROADCASTING SYSTEM Inc. 16 April, 1968, [17 April, 1967], No. 17540/67. Heading H4F. Specification describes method of and apparatus for recording the contents of a colour picture on "black and white" film in such a form that the contents can be readily read out by a flying spot scanner and converted to a colour television picture. The object to be viewed is focused by lens 13, Fig. 3, on to a black and white film 14. A banded colour filter 16, Fig. 4, is placed in front of and adjacent to lens 13, and a lenticular screen 15 is placed in front of the film. The colour filter comprises red bands 18, 21, green bands 19, 22, blue band 20 and opaque bands 17, 23 and the screen 15 is formed with a plurality of juxtaposed partcylindrical lenticulations arranged parallel to the filter bands. This results in there being formed on the film 14 a repeated pattern of coloured bands 18<SP>1</SP>, 19<SP>1</SP>, 20<SP>1</SP>, 211, 22<SP>1</SP>, 18<SP>11</SP>, &c., separated by unilluminated bands 24, 24<SP>1</SP>, 2411. The light intensity in red band 18<SP>1</SP>, for example, depends on the red intensity of the corresponding point of the object, and the sensitivity of the film is such that for a uniform white object the intensities of the developed bands are all equal. To reproduce the object, a flying spot scanner is used, the direction of scan being at right angles to the bands. The hue of the colour is determined by the phase of the signal with respect to the pulse signals produced by bands 24, 24<SP>1</SP> &c., and the intensity by the amplitude of the signal. The pulse signals produced by scanning bands 24, 24<SP>1</SP> &c., are thus used to phase detect the signals produced by the other bands. The thus produced "chrominance" picture C, Fig. 1 on the film 14 may be formed simultaneously with and at the side of a corresponding normal "luminance" picture L, possibly by means of a beam splitting device, or the luminance and chrominance pictures may be produced in succession, Fig. 6. The apparatus of Fig. 7 is used for said successive production, wherein the lenticular screen 34 is mounted in a frame Fig. 8 (not shown) whereby it is moved into position 34<SP>1</SP> in front of the film 30 during the chrominance exposure, and to position 34 during the luminance exposure. Colour filter 35 remains in front of the lens 33 for both exposures, the colour bands being dispersed during the luminance exposure. A cam arrangement 26 causes a claw 29 to engage in a perforation in the film and move said film through one frame distance between exposures and a shutter 31 covers the film during said movement. A telephoto lens 36 may be used.

Abstract: 386,228. Centrifugal gas-cleaners. WAGNER, F. H., The Tuscany, Stony Run Lane, Baltimore, U.S.A. June 21, 1932, No. 17558. Convention date, July 1, 1931 [Class 23.] In separating dust particles and the like from gases, the main stream of gas is divided into a number of sub-streams which are individually centrifuged, and the separated matter is projected into a collecting zone mechanically isolated 'from the course of the clean gas. The hollow vertical casing 8 has an inlet chamber 9 at its upper end, and the chamber has a tangential inlet 15. A number of hollow legs 10 with flared upper parts 11 communicating with the chamber 9 are arranged round the apparatus, and have counterweighted valves 12 at their lower ends. The casing 8 is closed at the bottom by an inverted conical wall 19 with a counterweighted valve 20. A number of separating unit tubes 31 are fixed inside the casing and their lower ends terminate in a chamber 87 from which the clean gas outlet 16 rises through the top of the apparatus. The chamber 87 has a wall 17 with a valve 18 connected by a pivoted lever 23 to the operating wheel 28. Each separating unit consists of interchangeable sections 34, Fig. 3, with helically arranged apertures 35 through which the separated particles are thrown. One end 36 of each section is enlarged to receive the end of the adjoining section. The bottom sections have no apertures and are secured by bolts to the inclined wall 38 connecting the outlet tube 16 with the wall 17. A sand seal 88, Fig. 3, is arranged at the lowest joint of each unit. A helical baffle 49 is arranged between a centre rod 47 and the wall of the unit, to give the passing gas a whirling motion. The fastening means 51, 52 at the end of the rod 47 secure the baffle 49 and also hold the sections of the unit in place. Radial partitions 86 between the tubes 8, 16 form compartments in which the units are isolated. The dust-laden gas from the entry 15 passes round the chamber 9 and the large particles are separated to fall into the flared parts 11 of the legs 10. The gas stream divides into a number of streams which pass through the tubes 45 into the separating units. Separated particles are thrown through the apertures 35 and fall into the hopper 19. The streams of gas from the units unite in the chamber 87 and pass out through the tube 16. Any dust carried by the gas through the units 31 is deposited in the chamber 87. In a modification, water or other liquid is supplied to the dust-collecting sections of the apparatus so that the separated dust is carried away by the liquid stream.
