Title: Improvements in or relating to electrically fired guns
IPC: F41A19/58
Filed: 1956-06-13
Abstract: 835,887. Firearms; electrically primed cartridges. SOC. MODERNE DE FABRICATIONS MECANIQUES. June 13, 1956 [April 20, 1956], No. 18328/56. Classes 9(1) and 119 A gun has an electric firing circuit including a first switch 11-16-13 operated by the trigger 18 and a second switch 31-34 which is closed when the gun is gripped at 32 for firing, which prevents accidental discharge of the gun and which can be releasably held inoperative by a locking device 35 as a further safety precaution. A dry battery housed in the butt has one terminal connected to an insulated firing pin 9 through the switch 11-16-13 and the other "earthed" to the weapon frame through a switch 31-34. In Fig. 4 the device 35 is shown locking the switch assembly 31-34. It can be moved from this position by pressing forward a thumb-catch 31 to pivot it about 32<SP>1</SP>. For training, a dummy cartridge containing an electric bulb and optical system may be loaded so that when the trigger is pressed a beam of light is projected along the barrel and on to the target. Ejector mechanism (Figs. 9 and 10) is operated when the barrel is hinged open for reloading which causes the nose 46<SP>2</SP> of a rod 46 to tilt a bell-crank lever 48 releasing a hammer 49 against a rod 51 carrying the ejector 51<SP>1</SP>. The opening movement also permits a cam 53 under a spring 55 to pivot on to a stop 53. When the weapon is closed after loading the toe of the cam 53 pushes back the rod 46 against a spring 47 to engage its end 46<SP>1</SP> on a catch 18<SP>2</SP> pivoted to the trigger 18. The catch 18<SP>2</SP> is not released until the trigger is pulled, so that ejection cannot take place if the weapon is reopened before firing. The hammer 49 is meanwhile recocked by means not shown. A cartridge is provided which has a metal head and flange 3 housing centrally a metal sleeve 2 containing a polepiece 5 surrounded by an annular insulator 4. The polepiece is connected to the sleeve by one or more bridge wires embedded in a priming composition 7.

Title: Improvements in bleaching compositions
IPC: D06L3/08
Filed: 1959-05-29
Abstract: At least one polyamine of the formula NH2(CH2CHR.NH)nH in which R is hydrogen or a methyl group and n is 1-4 is added to an aqueous bleaching bath containing a water-soluble metal chlorite, and having a pH of 2-7, in an amount sufficient to prevent the evolution of chlorine dioxide from the bath but insufficient to destroy the bleaching power of the chlorite.  Alkali or alkaline-earth metal chlorites, e.g. sodium, lithium, potassium and calcium chlorites, are preferably used and the concentration, in the case of sodium chlorite is preferably 0.1 to 20 grams per litre.  The polyamines, which may be in the form of their hydrochloride or phosphate salts, may be used at concentrations within the range of 10 to 500 parts per million by weight in a bleaching bath containing about 1,000 to 2,000 parts per million by weight of sodium chlorite or p  equivalent amounts of other water-soluble metal chlorites.  The bath may also contain buffers, e.g. Na2HPO4, NaH2PO4, polyphosphates, NH4HF2, sodium acetate and acetic acid, to maintain a constant pH, wetting agents, e.g. the salts of acylalkyl taurides, up to 0.50 moles of ammonium nitrate or alkali or alkaline-earth metal nitrate per mole of chlorite, to reduce corrosion of stainless apparatus, and 5 to 50 parts per million by weight, based on the solution of a chelating agent, e.g. ethylene diamine tetra-acetic acid, hydroxyethyl-ethylene diamine triacetic acid, imino diacetic acid, nitrilo-triacetic acid and symmetrical ethylene diamine diacetic acid and their salts, and citric, maleic, lactic and tartaric acids and salts of citric and tartaric acids, to minimize the action of iron and other metal ions, e.g. nickel and cobalt, in engendering the formation of chlorine dioxide.  The polyamine may be added to the bleaching bath as an aqueous concentrate containing the polyamine and an alkali or alkalineearth metal nitrate, a suitable concentrate having the composition: nitrate 20%-32% by weight, polyamine 5%-12% by weight and chelating agent 3%-10% by weight, the balance being water. Alternatively, the polyamine may be added to the bleaching bath as a solid composition containing the polyamine, preferably in the form of a hydrochloride or phosphate, an alkali-metal nitrate and a buffering agent, a suitable solid composition being: nitrate 30%-55% by weight, buffer 25%-50% by weight, polyamine (or salt) 8%-12% by weight and chelating agent 3%-20% by weight.  The bleaching of cotton, polyacrylonitrile and polyethylene terephthalate fibres is described. U.S.A. Specifications 2,358,866 and 2,526,839 are referred to.
