Title: Improvements in or relating to methods of printing fabrics
IPC: B41F17/00
Filed: 1930-09-24
Abstract: 359,662. Printing processes. JUST, F., Cerveny Kostelec, Bohemia, Czecho- Slovakia. Sept. 24, 1930, No. 28575. Convention date, April 28. [Class 100 (ii).] In a method of printing fabrics in which relief or intaglio rollers are employed and in which parts of the fabric are masked to provide non-printing at those parts, pieces of paper or like material out to various shapes are fed manually or mechanically between the fabric and the rollers, and are drawn in by the rollers. The improved method may be combined with known printing processes, e.g. spraying, manual printing, or batiks, the combined process being carried out either before or after the usual finishing processes.
Patent GB-1471284-A (GB)
Title: Method and apparatus for generating a travelling display
IPC: G09G1/14
Filed: 1974-06-27
Abstract: 1471284 Control of displays BUNKER RAMO CORP 27 June 1974 [27 July 1973] 28632/74 Addition to 1395922 Heading G4H A cyclically refreshed display device which generates a plurality of writing strokes for each display line, information characters being displayed by selectively changing the visible state of M bits of each of N strokes for each character, incorporates means for causing the display to travel in fractional stroke increments, comprising: counters 40 and 38, each unit increment of which corresponds respectively to a predetermined fractional stroke increment and to a full stroke increment of the display, means 72-90 for determining the number of predetermined fractional stroke increments by which the display is to be incremented, means 92 responsive to this number for incrementing counter 40 thereby, and means 106-150, 62, 60 responsive to the counter outputs for controlling both the stroke and the bit thereof at which display of the first of a series of characters begins. The present invention is a modification of the C.R.T. display of Specification 1,395,922 which displays alphabetic stock 10 codes and numeric prices in matrix form on staggered lines L2, L3 (Fig. 3A). Display data 18 is input to a memory 10 via a buffer 20, a detector 22 incrementing a counter 16 and a detector 34 adding an extra 0 or 1 bit according as the data is for line L2 or L3. During read-out under control of counter 12, this bit is detected at 44 and gate 52 or 68 is enabled at L2 or L3 time accordingly, the data passing to a generator 58 and a display 63. Circuitry 72-78 determines how many stored characters have still to be displayed, which number provides an output 94 from a circuit 92. The fraction of a stroke is one-third of a stroke (3 bits) here: the corresponding output 94 (e.g. 94A=3 bits) causes counter 40 to be incremented, counter 38 being incremented if there is an overflow therefrom. At the end of a line, one of gates 106 is enabled (depending on the output of counter 38) at the corresponding stroke in the next character time; the output from the gates is fed to a flip-flop 142 and a 6-character delay 146. A clocking input to flip-flop 142 and a flip-flop 62 is obtained from one of gates 136 at a bit time corresponding to the count in 40. The set output from 142 triggers the line retrace operation in the display; at the same time flip-flop 62 is reset to disable gate 60 to prevent display during line retrace. After 6 character times, delay 146 applies a set input to flip-flop 62, which is clocked by the output from 136, thus enabling gate 60 again. The net result of this is that the first strokes and/or bits of the first word are not displayed, and the corresponding portions of the next new word are displayed at the end of the line, the minimum portion being 3-bits (onethird stroke). A similar operation takes place for a non- travelling display, using gates 130, 134 enabled during bit 1 of stroke 1.
Patent GB-759919-A (GB)
Title: Process for the production of carbon black pigments
IPC: C09C1/56
Filed: 1953-10-16
Abstract: Carbon black is subjected, in dispersion in at least twice its weight of water, to disintegration by mechanical means, e.g. stirring mechanism, stirrer type autoclave or kneading machine, while the dispersion is externally heated, preferably to above 100 DEG C., e.g. 130-150 DEG C., under pressure, and solid carbon black is recovered from the dispersion.  The aqueous dispersion may contain substances which decompose with gas evolution on heating. In the Examples: (1) a dispersion of carbon black in water, which may contain a wetting agent, is heated in a stirrer autoclave at 138-140 DEG C, and the carbon black is separated from the dispersion and dried (2), (3) carbon black is treated with aqueous ammonia and then with aqueous hydrogen peroxide, or an aqueous dispersion of carbon black containing sodium methyl naphthalene sulphonate is treated with aqueous ammonia and hydrogen peroxide, and the resulting dispersions are heated with stirring to 80 DEG C. and 75 DEG C. respectively, with the result that ammonium nitrite, formed as the result of the action of H2O2 on NH3 is decomposed to nitrogen and water, and the carbon black is separated and dried: (4) an aqueous dispersion of carbon black containing azoisobutylic acid nitrile is heated and stirred at 90 DEG C. with formation of N2, and the carbon black is filtered off and dried.  Other decomposable substances referred to are urea nitrile, and hydroxylamine or its nitrite.  The treated carbon black, which is preferably that obtained from higher fractions of coal tar, e.g. crude naphthalene, or anthracene oil, or from petroleum products, is suitable as pigment for lacquers and printing inks, has high wetting power and gives oil suspensions of low viscosity.

Title: Improvements in braking devices suitable for winders, hoists and the like
IPC: B66D5/26
Filed: 1936-10-22
Abstract: 483,580. Winding-apparatus; brakes. GENERAL ELECTRIC CO., Ltd., FOSTER, H. H., and WHITMORE, F. L. Oct. 22, 1936, No. 28761. Addition to 426,394. [Class 78 (v)] [Also in Group XXXIV] The apparatus described in the parent Specification is modified in that: (1) an adjustable needle valve 9 is provided in an extension 6 of the valve 14, for connecting the pipe 4 to exhaust; (2) the differential gear constituting the governor comprises sun wheels 25, 25a mounted on shafts 24, 31 respectively, the shaft 31 being coupled to the winding shaft and to planet wheels 27, 28 carried by the flywheel 26; (3) the crank arms 15, 15a mounted on an extension of the shaft 24, are coupled by a pin- and-slot connection to links 16, 16a which are connected direct by the lever 17 to the operating rod 12 of the valve 14, and springs 18, 18a are provided in the slots in the links, said springs being initially loaded to transmit without deflection the force normally required to operate the valve 14. If the arms 15, 15a are rotated on account of a seized bearing in the differential, the valve 14 is moved to a position connecting the pipe 4 to the pressure supply to prevent application of the brakes, but by compressing the springs 18, 18a, the arms 15, 15a then move the valve in the opposite direction to restore control of the brakes to the driver and connect the pipe 4 to the exhaust via the valve 9 and so cause automatic application of the brakes. Should an exceptional overspeed occur such as might be caused by failure of the pilot valve 5 to operate the brakes, a governor on the drum shaft opens a switch whereby a clutch 29 locks the differential to effect rotation of the arms 15, 15a as above.

Filed: 1919-11-21
Abstract: 163,366. Laurency, G. C., and Vigier, M. Nov. 21, 1919. Carding-engines; lap-forming apparatus. - In order to arrange the fibres in parallel relation and to maintain this arrangement, they are taken from the main cylinder A, Fig. 1, by a doffer B working in the opposite direction to that which is usual, with the points of the teeth forward. The fibres are lifted from the teeth bv wires 3 arranged between the rows of teeth 2a and carried by sectors 4 mounted on rods 8 controlled by an eccentric 6 on the doffer shaft. When the teeth are in engagement with the main cylinder, the wires are laid at the roots of the teeth and rise gradually to transfer the fibres to a lap-forming device or a sliver-dividing device. The lap-forming device comprises an endless band E, Fig. 3, passing over guide-rollers 12 - - 21. The band advances laterally at each complete passage round the rollers by an amount equal to its own width. At the end of its pasage it is brought back by pulleys 22 23, 24, to the beginning of its course. When the lap attains a given thickness it is broken automatically and is rolled up on a roller 34<a>, by means comprising a roller 25 on a pivoted arm 26 held by a catch 27 on a disc 28 loose on the spindle of the roller 12. The lap-cutter 34 is carried by arms 30 loose on the spindle of the roller 13 and connected by a rod 29 to a pin on the disc 28. When the roller 25 is moved by the growing lap, the catch 27 is released and then comes into contact with a projection 36 on a disc 33 fast on the spindle of the roller 12. This causes the disc 28 to be turned through a revolution to move the cutter over to break the lap and carry it to the roller 34<a>. At the end of the revolution an abutment 37 releases the catch 27. The sliver-dividing device comprises a number of flexible blades H, Fig. 8, hung from a bar 38. These blades are formed wih openings 39 or are cut to form openings with adjacent blades. The blades are hung between rollers E<1>. G<1> driving belts A', C<1>. The pressure of the belts carries all fibres whose forward ends pass the holes 39, through the hole, and on over the belt C<1>. All fibres whose forward ends do not pass the holes 39 are carried on downwards over the belt A<1>. Specification 18781/00 is referred to.
