Title: An electrical igniter
IPC: F42B3/14
Filed: 1960-05-09
Abstract: 953,336. Electrical igniter for explosives. RHEINMETAL G.m.b.H. May 9, 1960 [May 15, 1959], No. 16395/60. Heading F3A. An electrical igniter for explosive charges has a capacitor which includes two coiled metal foils 1 with an insulating intermediate layer and an end face 3 which provide spark gaps in the ignition zone, wherein the resistance of the ionization path between inner and outer poles 4, 6, other than that provided by the spark gaps, is greater than that which would be provided by inner and outer poles having end faces coplanar with face 3. The inner pole is electrically connected to the inner foil and e.g. to the positive terminal of a source of current, while the outer pole is connected to the outer foil and the negative terminal. The outer pole comprises a metallic strip 6 which partially encloses the outer surface 5 of the coil and is so positioned that an insulating air gap is left between its face 7 and the end face 3 of the coils. Alternatively or in conjunction the end face of the inner pole may be similarly positioned relative to the coil face 3. The air gap prevents the build-up of an electric field between the poles which would adversely affect the formation of sparks across the end face 3 when a predetermined voltage is exceeded. In another form the outer pole comprises a metallic ring enclosing the capacitor and insulated from the inner pole by a disc placed on top of the flanged portion of the inner pole 2 and beneath the ring. In another form the coil is enclosed in the vicinity of the ignition zone by a ring of insulating material of synthetic plastic which extends beyond the end face 3 and provides a chamber for a primer charge. The outer and annular pole has an annular recess to accommodate the ring, and extends in like manner, so that its upper end terminates in the plane of the end face of the said ring. Specification 792,169 is referred to.
Patent GB-386344-A (GB)
Title: Improvements in or relating to the production of crepe yarns and fabrics
Filed: 1931-06-04
Abstract: 386,344. Crape yarns and fabrics. BRITISH CELANESE, Ltd., 22, Hanover Square, London, DICKIE, W. A. and MONCRIEFF, R. W., of British Celanese, Spondon, near Derby. June 4, 1931, No. 16405. [Classes 120 (iii) and 142 (iv).] In the production of highly twisted crape threads, the twist is applied in at least two stages with an intermediate treatment adapted to set the filaments in position. Such treatment may be with water, aqueous liquid, or other liquid having a mild softening action on the material of the filaments, such as alcohols, halogenated hydrocarbons, and esters such as ethyl acetate, or the treatment may be simply heating. The crape threads may consist of or contain cellulose acetate filaments, filaments of other organic derivatives of cellulose, regenerated cellulose, natural silk, cotton, or mixtures thereof, and may consist wholly or in part of staple fibre. The first twisting is preferably such as will cause a close packing of the filaments. The subsequent twisting is preferably effected by drawing the yarn axially from a rotating package as described in Specification 304,806, [Class 120 (ii), Spinning, twisting, &c.] ; the twist may be irregular as described in Specification 358,585. The wetting treatment may be facilitated by the addition of wetting agents ; wetting agents or hygroscopic substances may also be incorporated in the yarns or filaments. Wetting may be effected by winding the yarn on to perforated bobbins and forcing the liquid through under pressure or suction, or both, or by spraying, or by passing the yarn over wicks, rollers, or the like, or by applying water to the yarn simultaneously with the twisting operation. After the liquid treatment the yarn may stand, and the further twist be applied whilst the yarn is still wet, or ofter a partial or complete drying. Drying may conveniently be effected by means of the perforated bobbin apparatus used for impregnating with liquid. The crape yarns may be sized at any stage of their manufacture, e.g. with the sizes described in Specifications 348,589 and 357,169, or with the coatings described in Specification 352,451. Such sizes or coatings may be applied intermittently, as described in Specifications 362,523, 365,040 and 365,041. Lubricant such as olive or castor oil, or oleic acid may be applied to the yarn prior to twisting. Fabrics containing the finished yarn may be treated with swelling agents, e.g. as in Specifications 352,000, 356,233 and 357,084. If desired, the liquid used for the treatment of the yarn may itself be one capable of swelling the filaments in the presence of water, e.g. ethyl alcohol. Specifications 332,903, [Class 120 (iii), Yarns &c.], 357,576, 357,577, 375,355 and 386,374 are also referred to.
