Title: An apparatus for producing photographic images and printing plates
IPC: G03D13/00
Filed: 1963-02-08
Abstract: 983,802. Photographic image transfer apparatus. AGFA A.G. Feb. 8,1963 [Feb. 10,1962], No. 5276/63. Heading G2A. Two photographic sheets are pressed together to effect an image transfer by passing them between a rotatable heated drum and an endless band of water-tight elastic material of low heat conductivity. Suitable materials for the band are various silicone, butyl or nitrile rubbers. Because of the water-impervious nature of the band, the steam formed from the moisture present cannot escape outwardly, but is forced into the photographic layers. In the form shown, the exposed lightsensitive sheet and the transfer sheet (4a, 4b), after passing between moistening rollers 7a, 7b, are carried round between the heated drum 1 and the endless band 2. The guide rollers 3b, 3c are adjustable as shown. Specifications 790, 811, 801,053, 821,506, 843,974 and 853, 640 are referred to.

Title: Improved method of and means for consuming and utilizing smoke and waste products ofcombustion from furnaces
Filed: 1926-02-26
Abstract: 257,829. Brown, W. Feb. 26, 1926. Smoke-consuming.-Smoke from a furnace is consumed by passing it through a constricted passage where it is subjected to the action of a flame extending longitudinally of the passage and occupying the whole sectional area thereof, a stream of gas or air being admitted to the passage to support combustion. The flame may be produced by liquid or gaseous fuel or by an electric arc. Fig. 1 shows the invention applied to a boiler furnace the heat generated by burning the smoke being utilized. The smoke from the furnace 14 passes through a flue 17 into the smoke-box 2 and thence into a tube 1 traversing the boiler 3 where it is subjected to the action of the flame from a gas burner 5 and to air from a nozzle 6 supplied from a pipe 7 and fan 8 which also delivers air through a pipe 10 to the ashpit. The pipe 10 is provided with a rotatable elbow 11 which may be turned to discharge ashes accumulated therein. A modification is shown in Fig. 2 in which the smoke passes from the smoke-box 23 to a pipe 22 leading into the forced draught pipe 10 so as to deliver the smoke with air to the ash-pit from which part may be led direct to the fire and the remainder through a valve controlled pipe 24 to the end of a smokeconsuming pipe 20 where it is subjected to the flame from the burner 21 and air from the pipe 7 leading direct from the fan 8.

Title: Improved stamping or marking device, and application to yarn sizing and drying machines
IPC: D06C29/00
Filed: 1926-03-01
Abstract: 257,177. Howard & Bullough, Ltd., and Priestley, J. March 1, 1926. Yarns, marking and measuring.-a stamping or marking device for yarnsizing and other machines comprises a revoluble marking-roller e, Fig. 1, movable into contact with the material to be marked at predetermined intervals, the moving material effecting rotation of the roller to bring its marking area h into contact with the marking-liquid and to cause the roller to be locked in an initial position by a fixed stop. The roller e, mounted on a lever k pivoted at m to a pivoted liquid con. tainer n, carries a disc r having a notch s adapted to be engaged by a bowl t on a bracket on the container. When the lever k is turned by a flexible connection x to bring the marking-element h of the roller e into engagement with the warps on the drying cylinder b of the yarn-sizing machine, the bowl t leaves the notch s and rides on the periphery of the disc e while the element h makes contact with a colouring-roller o in the vessel n. After the connection x returns to its normal position, the roller e is stopped and the bowl t again engages the notch s. The flexible connection x is connected to a lever y carrying a loose pinion 2 geared to a pinion d in gear with the usual measuring-roller c. When long teeth 3, 21 on the wheels d, 2 come into engagement, the lever y is turned about its pivot to pull the connection x to the marking-device. In a modification, the connection x is operated from the Hitchon motion, shown in Fig. 4, in which vibrating levers 6, 7 alternately engage a stop 9 on a frictionally-driven disc 10. In order to operate the marking-device at each complete revolution of the disc 10, a second disc 11 having a projection 12 adapted to engage a pin 13 on the lever 14 is mounted on the disc 10 to control the flexible connection x of the marking- device. The marking-device may be applied to yarn-sizing machines in which the yam is air dried, the yarn being supported by a foundationroller behind the marking-roller.

Title: Cylinder inking device for printing machines
IPC: B41F31/30
Filed: 1934-02-20
Abstract: 431,277. Printing-machines. CAPDEVIELLE, J. P., 206, Rue St.-Maur, Paris. Feb. 20, 1934, No. 5653. Convention date, Feb. 20, 1933. [Class 100 (ii)] Inking-apparatus; tripping-arrangements.- Two forme-inking rollers 7<1>, 7<2> are supplied with ink from separate similar cascades of composition rollers 6<2>, 6<3> and metal rollers 4<1>, 43 and 4<2>, 4<4>, the first roller 4<1> of one cascade receiving ink directly from an ink supplying device only during the movement of the forme 1 towards the impression cylinder 20, and the first roller 4<2> of the other cascade receiving ink from the roller 4<1> through an intermediate roller 6<1>. The roller 61 receives more ink than the roller 6<2> but the difference in length of the paths over which the ink has to be spread results in a substantially equal distribution of the ink between the two rollers 7<1>, 7<2>. The rollers 7<1>, 7<2> are adapted to be separated from the forme 1 and from the rollers 4<3>, 4<4> upon. tripping of the cylinder 20. For this purpose the bearings of the rollers 7<1>, 7<2> are carried by a plate 10 having inclined parts 10<1>, 102 engaging corresponding inclined guides 11, 12. A rack 13<1> on the plate is engaged by a toothed sector 13 on a shaft 14 having an arm 15 connected by a link 17 to a lever 25 to which the eccentric bearing 22 of the roller 20 is connected by a link 23. A notched lever 26 pivoted to the lever 25 and to the armature of an electromagnet 57 is held normally clear of a roller 28 on a bell-crank lever 27 oscillated by a cam 29. The circuit of the magnet 57 includes two contacts normally separated by the sheets being fed to the machine. If a sheet is not fed, closure of the contacts causes the magnet 57 to move the lever 26 into the path of the roller 28. Movement is thus imparted to the links 17, 23 to move the plate 10 and bearing 22 to trip the rollers 7<1>, 7<2> and cylinder 20. The arm 15 is connected to the link 17 by a pin- and-slot, the pin being held normally in engagement with the inner end of the slot by means of a pivoted member 18. By raising the member 18, the movement of the link is not communicated to the arm 15 and the inking rollers may remain in operative position for inking-up prior to printing.

Patent GB-657840-A (GB)
Title: Improvements in circuit arrangements for pulse rate measurement
IPC: G01R23/00
Filed: 1949-03-03
Abstract: 657,840. Frequency and phase-difference measurements. BRITISH THOMSONHOUSTON CO., Ltd. March 3, 1949, No. 5847. Convention date, March 9, 1948. [Class 37] The average pulse repetition rates in two series of pulses, at least one of which has a random distribution, are compared by establishing the time interval from a pulse in the first series to the next following pulse in the second series, establishing the time interval from the latter pulse to the next following pulse in the first series, repeating this cycle a number of times, and obtaining a ratio of the average values of such two time intervals. In the modified Eccles-Jordan scale-of-two counting circuit shown in Fig. 1, two series of negative pulses, one or both of which has a random distribution, are applied to input terminals 13, 14, and thence to the grids of two valves 1, 2. The valve 2 becomes conductive responsive to each pulse in the first series and valve 1 becomes conductive responsive to each pulse in the second series, each valve remaining conductive until the arrival of a pulse of the other series. The average time, interval during which the valve 1 remains conductive is thus inversely proportional to the average pulse repetition rate in the first series, and the average time interval during which the valve 2 remains conductive is inversely proportional to the average pulse repetition rate in the second series. Thus a ratio of the average time deviation of the two operating states, or the reciprocal ratio of the average current through the two valves, is equal to the ratio of the average pulse repetition rate in the two series. This ratio is measured by a D.C. milliammeter 21 connected between the cathodes of the valves 1, 2. If the pulse distributions in the two series have a periodic relationship instead of a random distribution, the time intervals depend on phase relationships. In a modification the valves 1, 2 are replaced by gas-filled tubes, the meter 21 being connected between their anodes. In this case the triggering pulses must be positive. The average pulse repetition rate in a single unknown series may be directly measured by using a pulse series having a known repetition rate as a standard. A single instrument may be made to cover several ranges by using a standard having a different rate for each range. Alternatively, a standard having a variable calibrated repetition rate which may be varied to obtain zero D.C. through the milliammeter. In a modification a scale-of-two circuit is so arranged that one of its states of operation is always reassumed after a fixed time interval determined by the time taken by a capacitor to discharge. The ratio of the duration of the two operating states, and hence the indication of the meter, is thus directly related to the average pulse repetition rate in the pulse series measured.
