Title: Improvements in or relating to tripping mechanisms of rotary printing machines
IPC: B41F31/30
Filed: 1927-02-16
Abstract: 289,756. Linotype & Machinery, Ltd., and Dowson, R. Feb. 16, 1927. Divided on 288,405. Inking - apparatus.- Tn a rotary machine the cylinder-tripping means is combined with means for tripping the ink-applying rollers and the messenger-supply roller either automatically or by hand. Control means are employed to enable the inkapplying means to be tripped or untripped while the messenger roller remains either tripped or operative, irrespective of whether the means are operated by hand or by the cylinder-trip mechanism. The plate cylinder 1 is inked by rollers 43 which are supplied from a distributing-roller 46 receiving its supply from a duct roller 45 by means of an oscillating messenger 44 operated by a cam 47. The rollers 43 can be raised out of action by pivoted levers 53 connected to a shaft 50 which can be oscillated from a link 49 connected to the eccentric bearings of the cylinder 2. By means of a catch 67 the shaft 50 can be. automatically operated when the cylinder 2 is tripped, or the shaft 50 can be operated solely by a hand-lever 68. In any case, the rollers 43 are tripped when the shaft 50 is moved counter-clockwise. The movement of levers 53 to trip rollers 43 can also be made to operate a catch 61 which trips the messenger roller 44. A link 55 and spring 58 tends to raise a lever arm 57 with the lever 53 and by means of a. link 59 this movement is transmitted to the catch 61. The movement of link 59 is controlled by a slotted link 71 connected to a bell-crank 72 which can be held in one of three set positions by a spring-plunger engaging recesses in the machine frame. In the position shown the link 59 is held depressed and the catch 61 can be operated to trip the messenger roller. When the plunger engages recess A the catch 61 is operated simultaneously with the lever 53 so that the rollers 43 and the roller 44 are tripped. When the plunger engages recess B, the catch 61 holds the roller 44 permanently tripped independent of the tripping of rollers 43.

Title: Improvements in or relating to colour television systems
IPC: H04N11/22
Filed: 1948-03-04
Abstract: 641,309. Television. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. March 4, 1948, No. 6784. Convention date, March 6, 1947. [Class 40 (iii)] In a colour television system wherein the individual colour components of a picture are scanned in sequence, electronic storage devices are each fed with image signals representative of one colour and are arranged to be rendered operative in sequence so as to supply modulation for transmission when image signals of a different colour component are being transmitted. By this means signals due to each colour component may be transmitted continuously at a frequency high enough to avoid colour flicker and stroboscopic effects. The two-colour system illustrated operates at 50 frames per second and employs a camera C with two complementary colour filters inserted alternately in the light path. The camera signals pass to two electronic storage tubes A1 and A2 through an electronic commutator E synchronized with the alternation of the colour filters so that the image on each tube mosaic is renewed every <SP>1</SP>/ 25 th second. The tubes may be of the ionoscope or orthicon type with two scanning beams, one to produce the stored picture and the other for analysis to generate an output signal. Alternatively a single beam may function for both purposes. The arrangement is such that, during the scanning of the first colour frame, the signals pass to the corresponding receiver channel R1 through an amplifier D1 and are also stored in tube Al, the output circuit of which is blocked. During the following scanning of the complementary colour, the input to tube A1 and amplifier D1 are both blocked but the output of A1 is unblocked and feeds into channel R1. This results in signals due to the first colour being passed continuously into channel R1 at a repetition rate of 50 per second. Storage tube A2 and amplifier D2 function likewise for the complementary colour signals in channel R2. In a three-colour system the images on the storage tube mosaic are renewed every <SP>1</SP>/16th second and the tubes adjusted so that only partial discharge occurs during each scan.
