Title: Comb filter for video processing
IPC: H04N9/78
Filed: 1976-03-17
Abstract: 1536223 Colour television RCA CORPORATION 17 March 1976 [18 March 1975] 10672/76 Heading H4F Comb filtering of a buried subcarrier type colour television signal derived from a rotating capacitance-type video disc 14 and thus subject to frequency errors is effected by using a controllable delay line 20 as the one line period comb filter delay, the precise delay of the composite video signal in this delay line being controlled by means responsive to these frequency errors, e.g. any detectable phase difference between the colour synchronization bursts and a reference signal. The delay line 20 comprises a charge transfer delay line (bucket brigade or charge coupled), the delay of which is controlled in response to applied clock signals 54 of different phase derived from the output of VCO 42 which is controlled by the output of phase comparator 48 receiving the separated bursts 26 and a reference frequency 50. The VCO output is also used in modulator 40 to stabilize the chrominance subcarrier and render it jitter free. The luminance and chrominance components are obtained from adders 24 and 30 of the comb filter respectively. To restore any vertical detail removed by the comb filtering a portion of the output of adder 30 is added via filter 32 to the combed luminance signal.

Title: Improvements in or relating to means for transferring articles from separate conveyors to a single conveyor apparatus
Inventor: MEYER GEORGE L N
IPC: B65G47/68
Filed: 1964-03-13
Abstract: 1,001,034. Conveyers. G. J. MEYER MANUFACTURING CO. March 13, 1964, No. 10789/64. Heading B8A. Articles such as bottles 8, Fig. 2, are transferred from separate conveyers 4, 6 on to a single conveyer 20, the bottles actuating transfer means comprising starwheels 51 which are so geared to each other as to cause the bottle to be delivered from the conveyers 4, 6 alternately on to the conveyer 20 in single line fashion. The conveyers 4, 6 pass over sprockets driven by a chain 14 through a friction clutch 15, e.g. from an associated washer (not shown). Wear-plates 7, Fig. 3, are interposed between the conveyers and a frame 2 supporting the transfer means. The conveyer 20 is preferably driven at twice the speed of the conveyers 4, 6, by a filler (not shown), to which it delivers the bottles. The latter are guided from the conveyers 4, 6 by guides 32 and adjustable rails 36, the guides 32 converging to a point at which there is inserted between them a flexible plastic strip 35, and are guided on to the conveyer 20 by adjustable guides 52. The starwheels 51 are mounted on spindles 68 having bevel gears 60 which mate with gears 88 secured by splines on a shaft 90 so that the starwheels may be adjusted relative to each tother. The spindles 68 are disposed within sleeves 74 adjustably mounted in a cross-member 66 which connects supports 62, 64 secured to the frame 2, and adjusting forks 71 extend from the supports 62, 64 to laterally support the star wheels 51. Shaft 90 has secured to one end thereof an arm 92 having mounted thereon a spring-biased pawl 94 which engages a ratchet-wheel 96 fixed to a sprocket-wheel 98, the wheels 96, 98 being freely rotatable on a stationary bush 100. The sprocket-wheel 98 is driven from the tail shaft 22 of the conveyer 20 by means of a sprocket 26 and an interconnecting drive chain 25. In operation, the bottles 8 actuate the starwheels 51 which have pockets so disposed relative to each other that the bottles are delivered to the conveyer 20 alternately from the conveyers 4, 6. If the delivery speed of the bottles is such that the shaft 90 rotates slower than the ratchetwheel 96, the pawl 94 .s urged out of engagement with the latter but if there is a tendency for the shaft 90 to rotate faster than the ratchet-wheel 96, the pawl-and-ratchet engagement will limit the rotation of the shaft 90 to that of the ratchet wheel 96, thus limiting the number of bottles 8 fed to the conveyer 20.

Abstract: 610,396. Velocity-modulated tubes. PHILIPS LAMPS, Ltd. April 10, 1946, No. 11004. Convention date, Nov. 22, 1941. [Class 39 (i)] Velocity modulation discharge apparatus for generating oscillations comprises a modulating electrode assembly 8, 9, 10, a drift tube 11, a " pick-up " electrode assembly 12, 13, 14 back coupled to the electrode assembly 8, 9, 10 by a feedback line 18, 19, the electrode assemblies being traversed in succession by an electron beam, and at least one and preferably two coaxial stubs 20, 21; 24, 25, coupled to the electrode assemblies. If one stub is provided, this permits frequency variation accompanied, however, by variation of the feedback; it also necessitates adjustment of the average electron velocity so as to retain maximum output. If two stubs are used, the frequency can be altered without varying the feedback by altering their lengths equally, or alternatively the feedback can be altered without varying the frequency by lengthening the effective length of one stub and shortening that of the other by an equal amount. By altering the lengths of the two stubs unequally, a simultaneous variation in the frequency and feedback is obtained. The effective length of the stubs is varied by movable pistons 22, 26 having springs 23, 27 to provide good contact. Energy is abstracted either directly by means of a coupling loop, or from a third electrode assembly 28, 29, 30 having two symmetrically arranged stubs 31, 32; 33, 34 tuned by pistons 35, 36 with springs 37, 38. The oscillatory system 8, 9, 10, 12, 13, 14, 18, 19 may oscillate at a fundamental frequency or at a harmonic, and the frequency of the output electrode system 28, 29, 30 is equal to or a harmonic of the frequency of the generated oscillations. An axially directed magnetic field is provided by coils (not shown). In modified constructions, the electrode. systems and part of the stubs may be arranged internally of, or may form parts of, the tube wall. In the latter case, the stubs have internal glass or quartz partitions to complete the vacuum.
