Abstract: 1450826 Colour printing BENGT PETERSSON NEW PRODUCTS INVESTMENT AB 28 Aug 1974 37686/74 Heading B6C [Also in Division H4] A method of colour reproduction from an original comprises providing a printing forme 3 which consists of a plurality of uniform channels 16, terminating at one end in orifices forming a screen surface 6 and at their other ends in a chamber 17, scanning the original to provide signals indicative of colour values at points corresponding to each of the orifices in the forme, passing the signals to an ink-supply device which mixes and injects ink of the determined colour into each channel 16, placing a copy sheet 7 into contact with surface 6 forcing ink simultaneously out of all the channels 16 on to the copy sheet and repeating the printing step on succeeding copy sheets until the ink is exhausted in the channels. The ink is forced out by the admission of air under pressure to chamber 17 under the control of rotary valve 28 which also controls the lowering of impression surface 8 on to sheet 7. A similar printing forme could be substituted for surface 8 if it is desired to print both sides of the sheet; the method is also suitable for decorating curved articles. The injection device 40, Fig. 6, has a central bore 51 which may communicate with bores 52, 53, each set of bores 52, 53 supplying a different colour from receptacles (41), Fig. 3 (not shown). Needle valves 60 are controlled by electromagnets 59 actuated in response to the scanning signals from a photo-cell/colour filter arrangement (see Division H4).

Abstract: 316,088. Wade, H., (Aktiebolaget Formator). Dec. 27, 1928. Stripping.-In machines for stripping tobacco leaves, of the kind in which the stem is seized by a gripper and torn from the leaf, the gripper is arranged to move between feeding-rollers which, after the gripper has passed them, are brought together upon the stem so as to assist or replace the pulling action of the gripper, in order to prevent fracture or slipping of the stem at the gripper. Fig. 4 shows the rollers 6, 7 brought together against the stem 31, after the gripper 1 has passed downwards between them, one or both of the rollers being driven so as to feed the stem forwards and assist in its removal from the tip and leaf portions, which pass between the bands 2, 3.

Portions of leaf adhering to the stem are removed by a cutter 33 co-operating with a member 34 and carried by an arm 36 moving with the arm 16. Scrapers 27 prevent the stem from coiling upon the rollers, and keep the rollers clean. The gripper may be constructed as described in Specification 315,778.

Abstract: 1518148 Measuring the transmissivity of a sample fluid COMPUR-WERK GmbH & CO 18 Sept 1975 [9 Oct 1974] 38336/75 Heading G1A In a device for measuring the transmissivity of a sample fluid 28 in a cuvet 26 that is placed in a beam path defined by a lamp 16. lens 24. colour filter 30 and photo-cell 32, the photo-cell 32's output is fed to a differential amplifier 36. The differential amplifier 36 is also fed by the output of a further photo-cell 34 which receives radiation directly from the lamp 16. The differential amplifier supplies a meter 38 and is initially calibrated by a feedback "electronic regulating system" 40, 60. The feedback system is adapted to come into action when a reed switch 44 is depressed to adjust the voltages at the two inputs of the differential amplifier to the same potential, i.e. zero volts. The electronic regulating circuit comprises a differential amplifier 40 connected up as an integrator with a condenser 42 receiving the integrated voltage and a feedback circuit including a field effect transistor 62 and associated capacitor 64. The circuit is designed so that the effect of the calibration lasts long enough for the measurement to be made with the cuvet. The whole apparatus is intended to fit within a flat elongated case 10, Fig. 1, having an aperture 50 in which the cuvet 26 is placed. A movable optical wedge 22 is attached to a setting wheel 20. Initially the wheel is set to zero, then the differential amplifier 36 is calibrated before the cuvet is put in the aperture 50 and next the wheel is turned until the meter 38 reads zero again. The difference in readings on the setting wheel 20 is then taken to be a measure of transmissivity of the sample fluid.
