Title: Improvements relating to the method of and means for weaving tufted or pile fabrics
IPC: D03D39/02
Filed: 1928-07-06
Abstract: 317,193. Cowell, A. G. July 6, 1928. Pile fabrics. -Tufted or pile fabrics are woven with double the normal number of tufts in the width. The design is drafted on paper having double the normal number of divisions in the width and each line is set so that the tuft yarns of alternate divisions are wound on tuft tube bobbins of one frame and the remainder on bobbins' of a second frame, the frames and bobbins being mounted alternately in the carrying chains and operated so that tufts from alternate frames are inserted in alternate spaces between warp threads. The frame or cradle to which the frames are transferred, and by operation of which the tuft yarns are inserted in the warp, receives a slight lateral motion periodically in addition to its rise and fall. In a modification, the cradle is dispensed with, the tuft tubes on the two frames being out of line with each other. For reading-in the design, a comb, Fig. 2, is employed having seven teeth and seven equal spaces to the inch. One line is readin from the visible parts of the paper, and the comb is then shifted to cover these and disclose the remaining spaces from which the next line is read-in. In a further modification, each bobbin, Fig. 13, may have two rows of tubes t, t', relatively staggered, the design being then read-in straight across the line. Figs. 1 and 3 - - 10 indicate the mode of weaving. The sley and comb have each 14 dents to the inch. Alternatively, two adjacent combs having each seven teeth may be used, the combs being relatively staggered.

Abstract: 959,976. Cheques etc.; fraud preventing; handwriting comparing. TELEREGISTER CORPORATION. June 7, 1960, No. 19952/60. Drawings to Specification. Headings B6A and BOX. [Also in Division G5] A document comprises a surface bearing a composite scrambled cryptic presentation comprising informational bits of an intelligible display disposed in a plurality of spaced zone of said surface, which bits by themselves are sufficient to preserve the intelligibility of the display and random non-informational bits which if viewed by themselves as a group present no intelligible information or symbol, said random non-information bits being disposed between said zones so that the composite presentation is an unidentifiable display from which however the intelligible display can be identified when said non-informational bits are obscured. The informational bits may be derived from a signature or a picture. The preferred method of preparing the document is by a photographic process in which the signature or picture is photographed through a screen as is a sample of non-informational handwriting. From the latter photograph an encoding dummy is produced which may be in the form of a negative having the non-informational bits in the spaced zones between which are transparent zones corresponding in spacing to the spacing of the zones of informational bits in the first photograph. The document is then produced by printing from a photograph of the encoding dummy superimposed in aligned position over the photograph of the informational bits with the original screen interposed also in aligned position. In an alternative method the document may be produced from a photograph of the signature or picture taken through a screen bearing in the spaced zones non-informational bits of handwriting. It is preferred to leave a blank space between each line of informational and non-informational bits.

Title: Method for the production of double helical teeth
IPC: B23F7/00
Filed: 1921-07-26
Abstract: 167,172. Krupp Akt.-Ges., F. July 28, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Gear-cutting.-Double helical spur gears may be generated on the rolling principle by means of a milling-cutter B, the cutting-edges b<1> of which may be regarded as moving, during the rolling of the blank, along the flanks of a rack as shown in Figs. 1 and 2. The cutter is advanced along each half of the tooth flanks a<2>, a<3> in the direction of the arrows, and at the end of the advance movement the bounding circle b<2> of the cutter crosses the lines 3, 4, 6, 7, where the tooth flanks intersect at the intermediate points 5, 8 respecively. Thus at points near the centre line of the rack, part of the tooth flanks, as indicated by the non-hatched portions in Fig. 1, are not engaged by the cutter so that in cutting a spur-wheel C, Fig, 3, ribs c<1> will be left in the gaps between the teeth. In order to allow two gears cut by this method to engage fully with each other, a peripheral groove c<2> of V-shaped contour, corresponding to the cross-section of the rib c<1> is cut in the blank before the teeth are cut so that the cutter may be advanced freely up to the inner end positions shown in Fig. 1. The invention is stated to be applicable also to the milling of double helical bevel gears.

Abstract: 1363551 Bonding particles to supports NORDDEUTSCHE AFFINERIE 1 May 1972 [25 May 1971] 20230/72 Heading B2E [Also in Division Cl]  A process for bondin ga particulate solid to a support to which it does not adhere, e.g. to produce a composite adsorbent or catalyst, comprises successively adding two watersoluble substances, at least one of which is a flocculating agent, to an aqueous dispersion of the solid in the presence of the support, at least one of the agents having an affinity for the solid, the flocculating agent when jointly contained in an aqueous solution forming an adhesive water-insoluble composition which adheres to the support and encloses the solid. A latex of a water-insolulble substance such as an amine-activated acrylate copolymer may subsequently form a non-adhesive porous surface on the composition. One of the flocculating agents may be an acidic polymer such as homopolymer or copolymer based on maleic, acrylic or methacrylic acid, vinyl compounds or styrene, or the products of partial or complete saponification or decomposition of esters or amides. The other agent is basic, with, for example, a nitrogen containing group, such agents being polyethyleneimenes. The support may be precoated with a solution of one of the flocculating agents such as polyethyleneimine in which case a hardener, for example, epichlorohydrine, may be added before drying. Alternatively the support may be precoated with a solution of the two agents which is then dried. The particulate solid may be stannic acid in suspension. The support is preferably also granular or lumpy, such as sand or coke breeze. The particulate solid and support are preferably in an aqueous suspension to which the flocculating agents are added. The agents enclose the solid and coat each support granule.

Title: Process of producing photographs and kinematographic films in natural colours
IPC: G03C7/26
Filed: 1929-07-02
Abstract: 334,004. Lierg, F. July 2, 1929. Colour photography.-In a process for the production of photographic images, especially on kinematograph films, in natural colours, two or more silver halide emulsions of different colour sensitivity are superimposed with or without an intermediate layer of gelatin, one or more of the layers containing chemical agents which enable the silver images to be converted into coloured images independently. The intermediate layer may also contain substances which enable the layers to be treated separately. In an example with two layers, copper carbonate is added to one and ferric hydroxide or manganese carbonate to the other. After developing and fixing, the silver images are treated with potassium ferrocvanide, and then dipped in hydrochloric acid, copper ferrocyanide being formed in one layer and prussian blue or manganese ferrocyanide in the other. The copper ferrocyanide is treated with a thiocyanate. solution giving a red image, and when manganese ferrocyanide has been formed, a malachite green image is produced by treatment with alkali and a solution of leucomalachite green. The carbonate may be added to one layer only, the silver ferrocyanide in the other layer being converted into a mordant. e.g. silver iodide. The intermediate layer may contain a precipitant for the reagent used in treating one layer, e.g. barium carbonate when a toning bath containing iron salts is used, or may be dyed, e.g. with carmine, so that the gelatin of one layer after treatment with a bichromate may be hardened by light action, the gelatin of the other layer being unaffected. Specifications 113,617, 119,854, 193,069, 245,198, and 298,979 are referred to.

Title: Ink drop printers
IPC: B41J2/115
Filed: 1972-05-02
Abstract: 1392656 Ink-drop printers A B DICK CO 2 May 1972 [3 May 1971] 20300/72 Heading G4H An ink-drop printer 30-50 incorporates means 52-56 whereby the phase of the ink drops is tested and, if necessary, corrected at writing time. Ink is projected from a vibrating nozzle 34 and breaks down into drops 40 which acquire a charge which is representative of an applied video signal 10-12, the drops then being deflected on to paper 48 by an electric field 42-44. A clock 16 and a counter 14 produce test pulses in sets of four, every first and fourth pulse being fed with the video signal via an OR-gate 20 to the charging tunnel 30 to produce the charging signal of Fig. 2, consisting of a video pulse 24 between the two test pulses 22, 26 (there two pulses having an amplitude greater than the maximum video pulse amplitude). If the video signal is correctly imparted the the ink-drops as they are formed, then the signal will be correctly recorded on paper 48; in the event of any lack of synchronism between drop formation and video signal charging, an ink-drop will acquire the high charge corresponding to test pulse 22 or 26. In this case, the ink-drop will be deflected upwards to the level of two electrodes 52, 54 which are close enough to be bridged by the drop, when a transistorized switch is caused to emit a pulse which is used to change the state of a toggle flip-flop 60. The change in output from 60 combines with the test pulses in NAND-gates 62-68 to produce a change in the output from the last gate 66 which controls a tuned amplifier nozzle driver 36 which effects a 180 degree phase adjustment in the nozzle vibrations so that drops formed subsequently are brought back into phase with the video charging signals.
