Title: Improved treatment of textile fibres, yarns, fabrics or the like for obtaining effects of colour or lustre or both
IPC: D06P1/00
Filed: 1925-05-07
Abstract: 245,407. Naamlooze Vennootschap Nederlandsche Kunstzijdefabriek. Dec. 30, 1924, [Convention date]. Yarns, threads, &c., treating with liquids, gases, and vapours.-Differential lustre or colour effects or both are produced on textile fibre yarns, for example of silk, wool, cotton or artificial silk, by treating the fibres of which a part has a content of free sulphur whilst another part is free from sulphur, with an agent, rather than vat dyestuff, which produces a differential lustre or colour effect as between the sulphured and unsulphured portions. A precipitate of sulphur may be produced on the< >fibres on parts of the fibres by impregnation with an alkali metal or ammonium polysulphide and treatment with acid, or by impregnation with a solution of sulphur in an organic solvent followed by evaporation of the solvent; or alternatively, a fabric may be woven so that the weft is of unbleached viscose silk (containing sulphur), and the warp of bleached viscose silk. The colour effects may be obtained by treating the fabric so obtained with a dyestuff, such as Indanthrene rose, which produces a colour on the sulphured portion different from that on the unsulphured part; or the sulphur in the material may be converted into coloured compounds by solutions of metal salts or into colourless metal compounds, and in either case the metal sulphide either as such may act as a mordant for an organic dyestuff, in such cases if desired, the metal mordant may be subequently removed. The Specification as open to inspection under Sect. 91 (3) (a) includes broadly the application of sulphur to portions only of the materials, and refers to a modification in which the sulphur is deposited over the material and then removed from portions thereof by printing, for example, with a paste containing a solvent for sulphur, or by printing with a water-repellent medium such as wax and then treating the whole fabric with a solvent; it also refers to the use of solutions of the salts of the following metals for producing the desired differential effects-Copper, silver, nickel, cadmium, antimony, tin, iron and aluminium,- and states that the metal sulphide first formed may be subsequently converted into the oxide. This subject-matter does not appear in the Specification as accepted.

Filed: 1947-05-05
Abstract: 659,805. Pulse generating circuits. STANDARD TELEPHONES & CABLES, Ltd. May 5, 1947, No. 12085. [Class 40 (vi)] [Also in Group XL (a)] A pulse generating circuit comprising a cold cathode gas-filled sequence electric discharge tube of the type described in Specification 639,827 and connected for automatic firing as described in Specification 639,839, includes a squeg circuit for extinguishing purposes. The circuit comprises a tube 1 having an anode 2 and a serrated cathode 3 with a shorter starting gap 7 at one end and a smooth prolongation 8 at the other end forming a " squeg tab ". The projected area on the anode of the squeg tab is much larger than the projected area of any other of the cathode discharge surfaces. A pulse applied to the anode from terminal 11 via blocking condenser 9 and resistance 10 initiates a discharge at the starting gap 7 which then spreads automatically from gap to gap, the discharges being maintained by battery 4 at each gap after firing, without squegging, until discharge occurs at the squeg tab 8. Owing to the larger area of the squeg tab, the current now rises suddenly, and resistance 5 causes a squeg to take place which extinguishes discharges at all gaps, and the tube remains inactive until the charge on condenser 6 has leaked away. A train of output pulses is obtained at the secondary terminals of transformer 12.

Filed: 1940-07-29
Abstract: 542,534. Typewriters. ROYAL TYPEWRITER CO., Inc. July 29, 1940, No. 12307. Convention date, Aug. 28, 1939. [Class 100 (iv)] Sheet-feeding arrangements.-A sheet-holding member, such as a bail, which is spring-biassed into and out of engagement with the platen or other sheet-feeding member, is automatically moved into engagement with the sheet-feeding member in response to sheet-feeding movement of the latter. In the construction shown in Figs. 2 and 6, a paperbail D, provided with rollers 17 and mounted on rock-arms 10, is provided with a pivoted spring-urged pawl 40 having teeth 49 for co-operating with a pinion 31 loosely mounted on a hub 23 on the shaft 24 of the platen C. The pinion is provided with pins 37, 39 for engaging a pin 38 on a sleeve 32 secured to the hub 23. A coiled spring 34 urges the pinion clockwise and normally holds the pin 37 in contact with the pin 38. Before a sheet w is fed around the platen, the paper-bail is pulled forwards into the position shown in Fig. 2, the pawl 40 being thereby caused to turn the pinion anticlockwise and separate the pin 37 from the pin 38. When the platen is turned to feed the sheet, the pin 38 approaches the pin 39, and when the top edge of the sheet has passed above the rollers 17, the pins 38, 39 engage, the pinion 31 co-operates with the pawl 40 to initiate return of the paper-bail, and on completion of return by the usual toggle spring, the rollers 17 press the sheet into contact with the platen. Since the rollers engage the sheet when the top edge is a determined distance above the printing line, a uniform top margin on successive sheets is ensured. The top margin can be varied by altering the position of the pins 37, 39. The pins 37, 39 may be replaced by a plate. The teeth 49 are shaped to ride idly over the pinion if the platen is turned anticlcockwise.

Abstract: 1499081 Vacuum filler for containers ATLAS PACIFIC ENG CO 26 March 1976 [9 April 1975] 12326/76 Heading B8T A vacuum filler for containers has its valve constructed such that vacuum is applied to the container only when the liquid transfer passage from the supply bowl is closed, any liquid trapped in the transfer passage thereby being vaporized to flush out remaining air in the container and air passages. The valve body 24 is mounted with its valve face on the underside of a liquid supply bowl which is rotatable about a vertical axis. The valve body includes an air passage 41, a liquid transfer passage 46 and a conduit 38 to provide a connection between the air passage 41 and a source of vacuum. A rotatable valve 26 is mounted on the body 24 and has a channel 45 leading to the bowl, and a conduit 39. In operation, the container 31 is engaged with the valve body 24 via a seal 22 and the valve 26 is rotated to a first position (Fig. 5) in which the air passage 41 is connected to a source of vacuum via conduits 39, 38 and pipe 37, and the liquid transfer passage 46 is closed. Liquid trapped in the passage 46 vaporizes as vacuum is applied to the container and the vapour flushes the passage and container. The valve 26 is then indexed to the second position (Fig. 7) in which the passage 46 is in communication with the interior of the bowl via channel 45 and the air passage 41 is shut off. Liquid is thus drawn into the container. The vacuum source is shut off, and rotation of the bowl causes the pipe 37 to be open to atmosphere. The valve 26 is indexed to a third position in which air can pass to passage 41 via conduits 39 and 38 and pipe 37, and the liquid transfer passage 46 is closed. The container is thus released and removed. In a fourth position of the valve, all passages 46, 41 and 38 are closed.
