Abstract: Lacquers, plastics and viscose fibres are coloured red with 4:41-diamino-1:11-dianthraquinonyl as pigment.  In Examples (1) the pigment is ground with dioctyl phthalate, mixed with polyvinyl chloride, dioctyl phthalate, cadmium stearate and titanium dioxide and rolled to give a foil; (2) the pigment is ground with titanium dioxide and a nitro-cellulose lacquer; (3) the pigment, acetyl-cellulose, sodium chloride and diacetone-alcohol are kneaded, washed, dried and ground and added to an acetyl-cellulose and acetone spinning composition; (4) the pigment is ground with titanium dioxide and an alkyd-melamine bakeable lacquer; the pigment is ground with 1:11-dinaphthylmethane-2:21-disulphonic acid sodium salt and water and the suspension added to (5) a viscose composition and (6) a resin preparation containing a latex of a copolymer of isobutyl acrylate, acrylonitrile and acrylic acid, an emulsion of a methylolmelamine allyl ether modified with soya bean fatty acid and emulsified with Turkey red oil, a water-soluble methyl ether of a urea-formaldehyde condensation product and formic acid; (7) the pigment is kneaded with a 2:6-ditertiarybutyl-p-cresol-ethylene oxide condensation product and water and the paste mixed with a resin lacquer emulsion made by concentrating a mixture of a butanol-modified melamine-formaldehyde condensate, casein, urea, thiourea, borax, ammonia and water, followed by treatment with ammonium thiocyanate; and (9) the pigment is "bread-crumbed" with a polyamide of o  amino-undecanoic acid and the amide is spun.ALSO:4 : 41-Diaminodianthraquinonyl is conditioned by heating in water at a temperature above 100 DEG C. under pressure, or by swelling the pigment in sulphuric acid and treating with an organic solvent, or by acid-pasting and wet or dry grinding in the presence of salts or solvents.  The pigment may be used with a carrier such as aluminium hydroxide.  4 : 41-Diaminodianthraquinonyl is used in printing colours and in an example a printing paste is made by mixing the pigment with a 2 : 6-ditertiarybutyl-p-cresolethylene oxide condensation product and an emulsion made from a butanol-modified p  melamine-formaldehyde condensate, casein, urea, borax, thiourea, ammonium thiocyanate.  In a further example a cotton fabric is immersed in a dyebath containing a latex of a copolymer of isobutyl acrylate, acrylonitrile and acrylic acid, an emulsion of a methylol-melamine allyl ether modified with soya bean fatty acid and emulsified with Turkey red oil, a water-soluble methyl ether of a urea-formaldehyde condensation product, 10% formic acid and a pigment suspension obtained by grinding 4 : 4-diamino-1 : 11-dianthroquinonyl with sodium 1 : 11-dinaphthylmethane-2 : 21-disulphonate and water. The fabric is hardened and a red colouration is obtained.

Title: Improvements in or relating to the measurement of the carbon level in furnace atmospheres
IPC: G01N27/12
Filed: 1957-12-09
Abstract: 818,839. Furnace gas measurement. INDUGAS GESELLSCHAFT. FUR INDUSTRIELLE GASVERWENDUNG. Dec. 9, 1957 [.Dec. 20, 1956], No. 38143/57. Class 40 (1). The carbon content of a furnace atmosphere is measured by introducing into the furnace two test bodies which will absorb carbon and thus change in resistance; both bodies are at the furnace temperature and one is exposed to the atmosphere to be measured while the other is exposed to a gas mixture having a known carbon level; the difference between the resistances then gives a measure of the carbon. level of the furnace atmosphere. In the Figure. two identical resistors 2, 3 of iron or an iron. alloy, are mounted in a probe 1 and inserted in a furnace so that the atmosphere enters at 6. passes the resistance 2 and leaves at 7. The standard gas mixture, preferably of zero carbon content, enters at 8 and mixes with the furnace atmosphere after passing the resistor 3. The difference between the resistances is measured by the bridge 4. The bridge is initially balanced with the valve 9 closed, so that the standard gas flows round both resistances and leaves at 6. In a modification the second test body can be in an enclosed container filled with the standard gas and containing a substance capable of absorbing or releasing carbon to maintain the atmosphere at a known carbon level.

Title: Improvements in Pulse Generating Circuits.
Inventor: BAUST NORMAN CHARLES
IPC: H03K5/04
Filed: 1965-09-10
Abstract: 1,156,786. Pulse generating circuits. PLESSEY CO. Ltd. 9 Sept., 1966 [10 Sept., 1965], No. 38848/65. Heading H3T. In a pulse generating circuit arrangement, for converting one set of pulses into another set of pulses of rectangular waveform, an output from a mono-stable circuit 1 is fed to an integrating means 2 connected in the input of a switching means 3 which is controlled such that the switching means 3 operates to connect a voltage from the integrating means 2 to a voltage storage means 4, such as a capacitor, which at the end of the operate period of the switching means 3 stores the integrated voltage and feeds this voltage to the mono-stable circuit for controlling the unstable period of the circuit. The switch 3 may be a semi-conductor device and is closed only during the stable state of the monostable circuit. The opening of the switch 3 and hence the voltage at point e depends on the frequency of the input pulses a and the feedback circuit 2-4 operates to change the unstable period of the monostable circuit to keep the output mark-to-space ratio constant even though the frequency of the input pulses may vary from one constant value to another different constant value. The variable resistor VR1 provides variation of the mark-to-space ratio.

Title: Improvement in electric controls for electro-magnetic couplings
IPC: H02P29/00
Filed: 1961-11-01
Abstract: 925,439. Automatic speed control. HEENAN & FROUDE Ltd. Nov. 1, 1961 [May 1, 1961], No. 39029/61. Class 38 (4). [Also in Group XXIV] An eddy-current coupling has driving-shaft 6, driven shaft 10, and a D.C. field coil 2 energized from source S through solid state controlled rectifier CR. The gate 78 of the rectifier is associated with phase-shift circuit PS which is connected to reference voltage circuit RV. When the slider arm 56 of potentiometer P is in its uppermost position, the phase-shifted gate signal is incapable of triggering the controlled rectifier. Downward movement of the slider 56 develops a D.C. reference signal across resistors 26, 82, to trigger the rectifier. A velocityresponsive voltage, developed by tachometer generator G, is applied to resistor 52 in opposition to the voltage across resistor 26. Thus, once the selected speed is established by the difference between the reference and speedresponsive voltages, any fluctuation of output develops an error voltage which in turn alters the duration of conduction of the controlled rectifier. This action restores the coupling speed to the desired value. In a modification, a transistor is connected in series with a load resistor forming part of the phase-shift circuit and is controlled by the speed-error voltage, Fig. 3 (not shown). In another arrangement the transistor forms part of the circuit PS, control of the rectifier CR being effected by variable phase displacement of the gate signal, with no superimposition of a D.C. component upon the A.C. component of the gate signal, Fig. 5 (not shown). Specification 925,440 is referred to.
