Title: Apparatus for the transmission and reception by electrical means of visual images in colour
IPC: H04N11/12
Filed: 1947-10-29
Abstract: 666,480. Television. RADIO CORPORATION OF AMERICA. Oct. 29, 1947 [Oct. 30, 1946], No. 28896/47. Class 40 (iii). [Also in Group XL (c)] In a television transmission system in which each of a plurality of simultaneously developed signals each representative of a different component characteristic of an optical image is individually modulated on to a separate carrier wave, individual band-pass filters are provided which pass one modulation side-band and a vestige of the other modulation side-band of each modulated carrier. In the arrangement shown in Fig. 1 light from the image to be televised is directed on to three television cameras by means of a lens system 11, halfsilvered or dichroic mirrors 12, 13, and green, red and blue colour filters 15, 18 and 21, respectively and the colour selection signals supplied by each camera are modulated respectively, on to carrier waves of frequency f<SP>1</SP>, f<SP>2</SP>, f<SP>3</SP> (Fig. 3), by means of carrier wave generators 31, 41 and 51 and modulator devices 30, 40 and 50 respectively. The signals supplied by the modulator devices are then fed to vestigial side-band filters 32, 42, 52 arranged to pass, in addition to the vestigial bands, the whole of one side-band of the green signals, a partially restricted side-band of the red signals, and a still more restricted side-band of the blue signals, since the colour detail resolution of the human eye is less for blue than red and less for red than green, and the spacing of the green and red signals is arranged to be such that an additional carrier 82 for accompanying sound signals or for other signals such as facsimile signals may be interposed therebetween. The carriers and filters are arranged so that the signals supplied by the latter occupy adjacent portions of the frequency spectrum, as shown in Fig. 3, and these signals are combined and transmitted simultaneously. In a further arrangement, Fig. 2 (not shown), the red and blue signals are first modulated on to individual sub-carriers which modulate a main carrier modulated directly by the green signals and the main carrier is then fed through three side-band filters connected in series which are arranged to position the colour signals in the desired positions in the frequency spectrum.

Title: Centrifugal pumps rendered self-priming by means of their gap water
IPC: F04D9/02
Filed: 1929-09-27
Abstract: 332,465. Pfleiderer, C. July 16, 1929, [Convention date]. Starting, facilitating; balancing moving parts.- In a centrifugal pump the energy of the water passing through the gap between the impeller and the casing, is used to effect de-aeration by means of a jet apparatus consisting of inlet and receiver nozzles. On the inlet side of the impeller a is attached the wall b which forms a moving side of an annular nozzle, the other side c of which is stationary. The water from the gap passes from the nozzle in the form of a thin sheet, through the receiving nozzle d and accumulates in the vessel f. Any air escapes through the vent i and the water is returned to the suction chamber by the pipe, g which contains an automatic valve h. A similar arrangement can be used to balance axial thrust. The moving wall b of the nozzle is attached to the impeller as shown in Fig. 2 and the stationary wall c forms a throttling space H with the moving part. If the rotor moves to the left the nozzle widens and the pressure on the movable wall b diminishes. In a modification the pump is provided with a gap which varies with the axial position of the impeller and the nozzle takes the form of a separate jet pump. The water is deaerated by this apparatus and returned to the suction of the centrifugal pump. In another modification the nozzle is directed inwards towards the axis. Guide vanes k are mounted on the stationary wall c of the nozzle to impart the desired direction of flow to the outgoing water. The nozzle may be widened by the axial displacement of the wall c; this is effected by the rotation of the wheel l which causes the rotation of the wall c and its axial movement by means of a screw thread.

Title: Patch applying mechanism
IPC: B31B19/00
Filed: 1951-12-14
Abstract: 706,875. Affixing patches to envelopes blanks. SMITHE MACHINE CO., Inc., F. L. Dec. 14, 1951 [Sept. 6, 1951], No. 29352/51. Class 73 In a machine for applying window or similar patches to constantly moving blanks, the patches are severed from a web fed at a uniform speed. The web projects on to a cylinder having equally spaced cutter bars which is rotated by a Geneva gearing and a knife is provided adapted to sever the patch while the cylinder is at rest, the severed patch then being smoothly accelerated by the cylinder until it is transferred, by suction control means, to a constantly rotating suctionapplying segment. Envelope blanks 10 having windows 12 advanced at a constant speed between the spaced belts of conveyers 14, 16 are first engaged between a gumming segment 42 and a cylinder 48 to gum the window margins 47, Fig. 2, and then have patches 57 applied by a rotating suction segment 58 as the blank passes between it and a roller 60. These parts all rotate continuously with a peripheral speed equal to the conveyer speed. A web 72 of patch material is fed at a constant speed from a reel 70 by feed rollers 78, 80 and passes over rollers 84, 86, 88 on to a suction cylinder 90 intermittently rotated by a Geneva gearing 94, 96. The cylinder 90, rotated in quarter turns, has cutter bars 92, Fig. 5, housed in equally spaced slots 158, suction being applied to that part of its face, which extends from the point at which the web 72 reaches it to the point of transfer of the cut patch 57 to the suc-. tion segment 58. The cylinder 90 .comes to rest with cutter bars 92 opposite a knife 93 which is reciprocated by mechanism actuated by a crank 244 on a shaft 98 to effect a cut, pilot fingers 242 being provided to ensure that the blade 93 which is yieldably and adjustably mounted moves in the correct path. The leading end of the web 72 is always 45 degrees or half a step in front of the point of transfer to the segment 58 when the patch 57 is severed so that the cylinder 90 is always moving at its maximum speed which is equal to that of the segment 58, when the transfer begins so that to increase the length of patch severed the cylinder 90 is turned back, the knife 93 moving with it so that when the knife is actuated it is further from the transfer point but the leading end of the web 72 is at the same distance therefrom. The feed speed of the web must also be adjusted by suitable replacement of the driving sprockets 108, 122, Fig. 1. Suction is applied to the appropriate part of the cylinder 90 from just before the patch is severed until it reaches the segment 58, which then also has suction applied, at which point valve control means open the suction openings of the cylinder 90 to atmosphere. When the position of the knife is altered to adjust the patch length the points of operation of the valve control means are correspondingly altered. Specification 495,228 is referred to.
