Abstract: 1,128,337. Web coating apparatus. EUROKOTE, S.A. 29 Sept., 1965 [30 Sept., 1964], No. 41334/65. Heading D1L. Apparatus for the continuous production of high gloss paper comprises a coating unit consisting of two rollers, coating composition being applied to a paper web as it passes the nip of the rollers, which nip is adjustable by means of a pneumatic piston articulated to the major arms of levers on which the coating roller is carried. The level of coating composition in the nip is kept constant. Convex surfaced tensioning rollers are provided before and after the coating unit to prevent the paper web from folding, a cold roll being provided between the coating unit and one of the tensioning rollers. After coating, the paper web passes to a heated smoothing cylinder via a backing-up roller. The backing-up roller exerts a constant pressure on the smoothing cylinder by means of a pressing cylinder which bears against the backing-up roller, the pressure being controlled by pneumatic cylinders. The pressing cylinder is partly immersed in a tray of water, and transfers water to the backing- up roller for moistening the uncoated surface of the paper web. A reciprocating device carrying a doctor blade contacting the pressing cylinder is provided to remove grit from the said cylinder. The backing-up roller is carried on parallel levers the upward movement of whose short arms is limited by means of a stop. An adjustable guide roller is also provided to direct the dry coated paper web to a further treatment machine.

Abstract: 1,170,596. Electric correspondence control systems. FILOTECNICA SALMOIRAGHI S.p.A. Sept.16, 1966 [Nov. 19, 1965], No.41465/66. Heading G1N. The attitude of a body mounted on a body carrying a gyroscope is automatically stabilized by electric signals from the gyro. As applied to stabilizing the attitude of an instrument mounted on a ship an attitude gyro g Fig. 1, on the ship produces an alternating voltage giving an indication of roll amplitude, frequency and mean list of the ship. This voltage, after amplification at a, is applied to a demodulator c which also receives a reference voltage from an amplifier b. The direct voltage output of demodulator c is applied through an amplifier d and biased diode limiter e to produce an output which is utilized to stabilize the instrument. To eliminate drift, the limited output signal is also applied through an integratoramplifier f as negative feedback for combination with the output of demodulator c. Suitable transistor circuits are outlined.

Abstract: 1284970 Photo-sensitive aluminium plate FUJI PHOTO FILM CO Ltd 28 Aug 1970 [1 Sept 1969] 41615/70 Heading G2C A photo-sensitive plate is prepared by immersing in a liquid an aluminium plate having thereon a porous oxide layer formed by anodization and subjecting the immersed plate to ultrasonic vibrations whereby a photosensitive material is deposited or formed in the pores of the oxide layer. The ultrasonic vibration frequency may be 10-40 kc/sec. and be applied for 10-300 seconds. The plate may be immersed in a solution or successive solutions, e.g. of silver nitrate and potassium bromide or chloride, which deposit silver halide in the pores of the layer. The photo-sensitive material in the pores may be a diazo compound, ferrous ammonium citrate and a red puissiate, an organic halogen compound and diphenylamine, a compound which changes colour depending on pH and a compound convertible to an acid or base upon light irradiation, a quinone diazide derivative, a leuco compound and an organic halogen generator and a photo-chromic dye. When the photo-sensitive material is silver halide the plate is generally exposed, developed, fixed, washed with water, intensified and sealed to obtain a high density image. Intensification may be effected using a solution containing gold chloride and sealing using a hot solution of a nickel salt or boiling water. The ultrasonic vibrations push air out of the pores in the oxide layer and simultaneously deposit or form therein the photo-sensitive material from a solution or successive solutions.

Abstract: 1,157,650. Jigger machines. VALD HEN RIKSBN A.S. 19 Sept., 1966 [23 Sept., 1965], No. 41625/66. Heading D1L. In a jigger machine for dyeing or other liquid treating fabric webs consisting of a vat for the treatment liquid through which the fabric web is passed as it is alternately wound and unwound on two main rollers driven by a two-speed motor with an automatic reversing mechanism, which normally reverses the motor when substantially all the fabric web has been wound onto either of the two rollers, means are provided for enabling said mechanism to 'be reversed at any stage during the passage of the web between the two rollers at intervals of time shorter than said normal interval, which corresponds to the substantially complete transfer of fabric from one roller to the other, but which shorter intervals are at least as long as the time required for the slower of the two rollers to complete one revolution, the two-speed' motor being so controlled by the reversing mechanism that it is switched to its slower speed operation simultaneously with the reversing mechanism being switched from normal reversing to reversing at said shorter time intervals. Preferably the mechanism is reversed by said means after at least one complete revolution of the slower roller. The means for causing the more frequent reversals may be a manually operable switch or a time-controlled switch. In use the automatic mechanism is caused to reverse at the shorter intervals when inspecting the webs or undertaking other operations necessitating stoppage of the full passage of the web between the rollers. The short-time reversals are in the nature of oscillations which prevent damage to the web at the bottom of the rolls during such periods through the excessive collection of the treatment liquid through gravity.

Filed: 1959-12-11
Abstract: 982,701. Regenerated cellulose filaments. COTTON SILK & MAN-MADE FIBRES RESEARCH ASSOCIATION. Feb. 27, 1961 [Dec. 11, 1959], No. 42117/59. Heading B5B. The instability of structure of a regenerated cellulose yarn is reduced, while the yarn is being travelled continuously, by wetting it with water at each of a plurality of stations, and drying it by the application of heat after each wetting station, and so controlling the wetting operation that the content of absorbed moisture in the yarn attains substantially the critical value. The critical value is defined as equal to the absorbed moisture content value that would be reached if the yarn were exposed to air at room temperature and at a relative humidity of 100% for a sufficient length of time for equilibrium conditions to be established. The tow may be viscose rayon, and the process may be carried out continuously on a yarn as it is produced by extrusion. Drying may be effected by passing the tow in contact with the heated surface of a roller, preferably heated to at least 100‹ C., and the number of wetting stations may be from two to ten. The tow may be progressed in a series of laps about a pair of yarn advancing rollers, one at least of which is heated. Both rollers may be heated, the tow being wetted at the requisite number of stations. The wetting stations may be adjacent to a roller surface, or displaced therefrom. One roller may be of considerably larger diameter than the other and may be heated, the other roller guiding the yarn to the wetting stations. In Fig. 1, A and B are heated thread advancing rollers, long enough to contain twenty laps of yarn. The yarn passes on each lap from roller A to the immersion roller C, where it takes up water which is absorbed during passage of the tow from C to roller D. The distance CD is adjusted so that by the time the yarn contacts the heated roller B, its absorbed moisture content is substantially the critical value. The roller D runs in contact with roller B and may be used to squeeze out excess water from the yarn and thus facilitate drying. The length of contact of the yarn with rollers A and B must be sufficient to ensure drying of the yarn before re-wetting for the next cycle. In Fig. 2, A and B are heated thread advancing rollers, and the rollers E, F thus supply water to the yarn when it is at a higher temperature than in the previous method. Penetration of water into the yarn is thus more rapid, but the two rollers E, F are necessary to ensure that the absorbed moisture content of the yarn reaches the critical value, in view of the higher rate of evaporation of moisture from the yarn. In Fig. 3, A and B are thread advancing rollers, A, which is heated, being of much larger diameter than B, e.g. A may be 24 inches diameter, and B 1¢ inches. B is immersed at any required depth in the water tank R, which is slidably mounted in guides G, and the length BD may be adjusted.

Abstract: 968,854. Automatic gain control. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 8, 1960 [Dec. 11, 1959], No. 42282/60. Heading H3Q. . In a television receiver contrast is controlled by variation of the grid bias of an I.F. stage 4 by means of a cathode circuit potentiometer 14 and automatic gain control (A.G.C.) is obtained from a stage 6 subsequent to the video 'detector, 5. To obviate interaction between the contrast control and A.G.C., the actual gain control voltage is derived from a potentiometer Rl, R2 connected between the stage 6 and the slider of the potentiometer 14; a diode 11 prevents the gain control voltage going positive. The resistance R1 may alternatively be connected to the cathode end of the potentiometer 14 (Fig. 3, not shown). The A.G.C. may be of the meanlevel type and derived from the grid of a synch. separator (Fig. 4, not shown). To prevent saturation of the final video amplifier 10, Fig. 5, when the signal is unmodulated, a voltage from the frame scanning generator is applied to the anode of a diode 12, which is normally biased to cut off by the voltage applied to its cathode from the anode of the final video amplifier 10. When the latter saturates its anode voltage falls, lowering the bias on diode 12 and permitting pulses to pass via condenser C5 to the A.G.C. circuit, where they are rectified by diode 11 to provide a negative bias on the A.G.C. line, so preventing overloading.
