Title: Improvements in processes for dyeing or printing fibres of all kinds
IPC: D06P1/00
Filed: 1923-10-22
Abstract: Fibres of all kinds are dyed or printed by reducing tungstates or molybdates by means of aluminium or magnesium amalgam.  The amalgam may be prepared by immersing bars, wires, or shavings of the metal in a solution of mercury cyanide or oxycyanide and preferably heating. An example shows the preparation of a bath for dyeing fibres blue comprising aluminium amalgam, ammonium molybdate and dilute hydrochloric acid solution, the temperature being raised to initiate the reaction.  The amalgams may be enclosed in an infusing bag, and when they have turned black may be amalgamated again.

Title: Improvements in cross-linking liquid copolymers of diolefines
Inventor: COOPER WILFRID
IPC: C08C19/36
Filed: 1955-09-24
Abstract: An oil copolymer of a conjugated diolefine and an olefinically unsaturated carboxylic acid is cross-linked by heating with an oxide of a polyvalent metal.  The diolefine may be butadiene-1,3 or a homologue; the acid is preferably mono-carboxylic and alpha-beta monoolefinically unsaturated particularly acrylic, methacrylic and sorbic acids.  The monomers may be copolymerized in any known manner giving a liquid product.  The copolymers may contain 4 to 20% by weight of the acid and have an intrinsic viscosity in benzene at 32 DEG  C. of less than 0.25.  The metal oxide is preferably an oxide of a di- or tri-valent metal including the oxides of zinc, cadmium, lead (litharge, Pbo), calcium and magnesium.  It is preferably employed in excess of the stoichiometrical proportion required to effect cross-linking and may be 10 to 100% by weight of the copolymer.  The products yield like plastic materials under a slowly applied stress but behave as resilient elastic materials when subjected to a sharply applied stress.  In an example, 90 parts by weight of butadiene and 10 parts of methacrylic acid were polymerized at 50 DEG  C. for 40 hours to 63% conversion in an aqueous medium containing "Teepol" (Registered Trade Mark), tertiary dodecyl mercaptan and potassium persulphate.  The liqud product contained 11.3% by weight of methacrylic acid and had a bulk viscosity of 44 poises at 70 DEG  C. This was cross-linked by heating with varying amounts of zinc oxide from 20 to 100% by weight for two to three hours at 50 DEG  C.

Abstract: 1391344 Printing apparatus NIPPON STEEL CORP and SAGINOMIYA SEISA. KUSHO KK 12 June 1972 [11 June 1971] 27429/72 Heading B6C [Also in Division G3] Printing apparatus comprises a conveyer belt 2 feeding steel or veneer sheets 1 to a print drum 16 carrying a printing plate 17 and rotating at a speed determined by a directlycoupled hydraulic drive motor 19 whose servovalve 14 is controlled by the circuit shown in Fig. 2, whereby for each fed sheet the drum is rotated one revolution, is started when the sheet is at a predetermined position from the drum and is accelerated to a speed to equalize the speed of its plate 17 with the speed of the sheet 1. In a typical one-off operation, a member 8 (photo-cell or a magnetic or capacitance detector) detects the leading edge of the sheet 1 and actuates a monostable vibrator 9 to open a gate circuit 7 and so allow the output of a pulse generator 5, representative of the speed of conveyer 2, to pass to a register 11, the vibrator 9 being adjustable to variably delay the opening of the gate circuit and thus vary the position of engagement of members 1, 17. The register 11 is part of an analyser 10 having a second register 12 receiving the output of a pulse generator 20 representative of the speed of the drum, a comparator producing an output representative of the difference between registers 11, 12 and a digital-to-analogue converter receiving this output and producing a control signal modified as necessary to allow for variable parameters such as print drum diameter. This signal is applied to a servo-amplifier 13 controlling the servo-valve 14, whereby the drum is accelerated to the correct speed before engagement of members 1, 17 and maintained at this speed during printing, after which the generator 20 produces a timing pulse to close the gate circuit 7 and clear the registers 11, 12 to respectively stop the motor and reset the analyser 10. The described operation also occurs for sheets fed almost continuously, although in this case the drum rotation does not stop completely.

Abstract: 1,152,266. Air brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. 13 June, 1967 [20 June, 1966], No. 27449/66. Heading F2F. In a system where air supply lines 5, 7, Fig. 1, act respectively upon a " spring applied " brake actuator 2 and an " air-applied " brake actuator 3 both operating on a common brake (not shown) via rod 4, an interlock 9, 11, 12 is provided between the lines 5, 7 whereby, upon application of the brake by one actuator 3, operation of the other actuator 2 is at least partly inhibited. The interlock consists of a double check valve 9, a pressure regulating valve 11, and a one-way valve 12; the valves 11 and 12 being combined in one modification (Fig. 2, not shown) and all three valves being combined in a composite valve (9/11/12, Figs. 3, 4, not shown). Operation.-With line 5 under full pressure to release actuator 2, a rise in pressure in line 7 causes actuator 3 to apply the brake. The pressure in line 13 is less than the pressure in line 7 by an amount determined by the regulating valve 11, and is applied to check valve 9 which applies to the spring-applied actuator 2 the higher of the two pressure inputs 5, 13. Thus, if the pressure in line 5 falls, the actuator 2 cannot be operated by more than the amount determined by the pressure at 13. The valve 12 allows for release of pressure at 13 upon a pressure drop in line 7. Composite valve (Fig. 4, not shown).-One input (21) is connected to line 5, Fig. 1, and a second input (22) to line 14, the output (23) connected to the line 10 receiving one or other input pressure according to whether a valve closure member (27) rests on a first valve seat (25) or a second valve seat (24). The closure member (27) has two relatively slidable parts (28, 29) held together by a first spring (30), and the member is biased to normally close one input (22) by a second, stronger, spring (26) which provides the function of the pressure regulating valve. Increase of pressure at the second input (22) causes the slidable part (28) to close the first input (21) before the other slidable part (29) opens the second input (22).

Filed: 1926-11-03
Abstract: 284,035. British Alizarine Co., Ltd., Dawson, W. H., Souter, C. W., and Anderson, J. Nov. 3, 1926. Benzanthrones are produced by condensing anthraquinones or the corresponding anthranols with the reaction mixture obtained bv treating glycerol with a sulphur-containing chlorinating agent such as sulphurmono- or di-chloride, thionyl chloride, or sulphuryl chloride; a dehydrating condensing agent such as sulphuric acid is also present. Some of the products contain sulphur and yield compounds of the violanthrone type by the usual treatment such as fusion with alcoholic potash. According to examples anthranol is condensed, in presence of sulphuric acid, with the reaction products from glycerol and thionyl chloride, sulphur dichloride, or sulphur monochloride; the benzanthrone derivatives thus obtained from the thionyl chloride or sulphur dichloride products yield violanthrone dyestuffs on alkali fusion but that from the sulphur monochloride product yields a yellow dyestuff probably of the dibenzanthronyl type.
