Title: The protection of polyamide textile materials
IPC: D06M11/01
Filed: 1966-02-10
Abstract: Synthetic polyamide textile materials in the form of filaments, fibres, flocks, woven or knitted fabrics, and non-woven sheets, are protected from discolouration and loss of mechanical strength under the action of heat and/or light by treating them with a borohydride. The borohydride may be lithium, sodium, potassium, calcium or magnesium borohydride or an ammonium borohydride in which the ammonium group is organically substituted by four alkyl radicals, e.g. cetyl trimethyl ammonium borohydride or tricapryl methyl ammonium borohydride.  The borohydride may be applied from an aqueous alkaline solution of 0.02-4.1 N caustic alkali or from an organic solvent solution, e.g. in methanol, ether, benzene or hexane, the solution preferably containing 1% by weight or less of the borohydride.  The solution may be applied by padding for 5-20 seconds or by conducting the textile material through a bath of the solution for up to 5 minutes, the textile material then being wrung out, optionally stored in the moist state in rolls for up to 48 hours and then dried.  The borohydride may be used in combination with other polyamide fibre-protecting agents, e.g. hypophosphites, sulphites or oxalates.

IPC: F23C99/00
Filed: 1934-02-23
Abstract: 421,097. Vapour burners. PIZZI, D., 19, Rue de la Fraternite, Esbly, France. Feb. 23, 1934, No. 5975. [Class 75 (i)] Liquid fuel sucl as a heavy oil is supplied through a pipe 1 to a vaporiz ing tube 3 and the vapour issues fron the tube 3 througl apertures 6 into a surrounding cham ber 11 where it is mixed with air supplied under low pressure. The mixture passes through apertures 12 in the chamber 11 into a combustion chamber 13 where it is ignited, the flame issuing in a horizontal or inclined direction through an outlet 14. At starting alcohol, admitted through an aperture 15 normally closed by a plug, is burnt in the lower part of the combustion chamber. A regulating valve 2 for the fuel supply and a regulating valve for the air supply are operable simultaneously so as to ensure the correct proportioning of the combustible mixture. The lower part of the tube 3 is corrugated so as to form a number of fuel compartments 5 and a number of vanes 10 are provided around the tube 3 leaving diminishing segmental gaps between their upper surfaces and the wall of the chamber 11. Unvaporized fuel escapes through a pipe 20 to a recovery tank and may operate means to cut off the fuel supply.

IPC: C07C265/04
Filed: 1965-02-15
Abstract: An organic a -isocyanato alkyl, aralkyl, aralkenyl or cyclic aliphatic ether is obtained by reacting an a -halogeno-alkyl (-aralkyl, -aralkenyl or -cyclic aliphatic ether with an alkali metal, ammonium, or alkaline earth metal cyanate at 0 DEG  to 200 DEG C. in a solvent mixture composed of 0.01 to 80 volume per cent of a strongly polar solvent as defined below and 99.99 to 20 volume per cent of an aliphatic, cycloaliphatic, araliphatic or aromatic hydrocarbon. The term "strongly polar solvent" refers to a solvent which has a dielectric constant greater than 15 and which does not contain Zerewitinoff-type active hydrogen, e.g. a tertiary amide, carboxylic acid nitrile or a dialkyl dicycloalkyl, aralkyl or diaryl sulphone and several such solvents are specified.  Other strongly polar solvents specified are nitroethane, nitropropane, nitrobenzene, nitrotoluene, acetone and acetophenone.  The hydrocarbon present in the solvent may be e.g. toluene, benzene, xylene, mesitylene, diethyl benzene, isopropyl benzene, ethyl naphthalene, octane, petroleum ether, gasoline, cyclohexane or methyl cyclohexane.  Several examples are given and among the isocyanate products obtainable by the process are those of the general formula R-O-CH(R1)-NCO wherein R is an aralkyl radical, an alkylene radical connected to an O-CH2-NCO group, a Cl-CH2-CH2-radical or CH2=CH-CH2-radical and R1 is a hydrogen atom or an alkyl or aryl radical and the invention includes such products per se as well as the compound C6H5CH.(NCO).O.CH3 formed in one of the examples.  Methoxymethyl isocyanate obtainable by the above process can be reacted with O,O-dimethyldithiophosphoryl acetic acid in methylene chloride at 40 DEG  C. to form O,O-dimethyl dithiophosphoryl acetic acid N-methoxymethylamide which is effective as an insecticide and acaricide.ALSO:A composition having insecticidal and acaricidal properties is obtained by mixing O,O-dimethyl dithiophosphoryl acetic acid N-methoxymethyl amide with the same amount of dimethyl formamide, adding benzyl hydroxy diphenyl polyglycol ether as emulsifier and then diluting with water.

Abstract: 608,739. Radio signalling. FERRANTI, Ltd., and WOOD, H. March 5, 1946, No. 6797. [Class 40 (v)] In a super-regenerative responder interference with a nearby radar set is prevented by deriving a control voltage in response to a timing impulse from the radar set and applying it to paralyse the quench oscillator in order to render the responder inoperative during the operative period of the radar set. Fig. 1 shows a responder of the type described with reference to Fig. 1 of Specification 601,574. The paralysing pulse is applied, however, to the grid of the quench oscillator valve 77 instead of to the super-regenerative amplifier valve. In a modification of the circuit of valve 48 as shown in Fig. 3, the battery GB is dispensed with, resistors 50, 72 and 71 being chosen to provide normally a cut-off bias but to allow the bias to be reduced to zero for most of the duration of the positive swing developed across network 44 at the start of the suppression pulse period. Specification 608,684 also is referred to.
