Title: Firing mechanism for percussion caps
IPC: F42C1/02
Filed: 1976-03-04
Abstract: 1524895 Generating combustion products under pressure WALLOP INDUSTRIES Ltd 23 Feb 1977 [4 March 1976] 08791/76 Heading F1L [Also in Division F3]  A firing mechanism for firing a percussion cap 4 comprises a leaf-spring 5 fixed at one end at 6 and carrying on its underside at or near the other end a firing pin 8, and a manually operable engagement device which can be raised to stress and subsequently release the spring to cause the pin 8 to strike the cap 4. In one embodiment Fig. 2 the engagement device comprises a pivoted lever 9 having a base cut-out through which the other end of the spring 5 protrudes to rest on a lip 24. As the lever 9 is raised the lip 24 causes the spring 5 to be flexed until a position is reached at which the spring 5 clears the lip 24 and is released. A weight 25 can be mounted on the spring above the firing pin 8. In another embodiment Fig. 7 the lever 9 is double-armed and has a catch 11 at one end which normally engages beneath the spring's free end. Pressure in the appropriate sense on an extension arm 12 of the lever 9 causes the catch 11, and hence the spring's full end, to be raised, flexing the spring, until at the release position, the catch and spring automatically disengage. In a further embodiment Fig. 8 the engagement device comprises a flexible plastics strip 14 extending transverse to the spring and secured at one end 15. An edge margin 18 of the strip 14 engages beneath the spring's free end so that, on raising the strip's free end 16 the spring is raised and flexed and eventually released. Applications mentioned are activation of a fire extinguisher, pressure inflator and, specifically, a pyrotechnic device comprising a charge 20 (Fig. 2).

Filed: 1946-03-22
Abstract: 610,096. Yarns and threads; fabrics. OSBORNE, W. F., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. March 22, 1946, No. 8965. [Classes 120(iii) and 142(iv)] A composite yarn consists of fibres or filaments of wool, cotton or other cellulose type fibres, viscose or cuprammenium regenerated cellulose, regenerated protein or cellulose acetate as major components and from 1 to 50 per cent of staple fibres or continuous filaments composed essentially of one or more highly polymeric linear esters obtained by heating one or more glycols of the series HO(CH 2 )nOH (where n is greater than 1 but not exceeding 10) with terephthalic acid or an ester-forming derivative thereof, such as its aliphatic (including cyclo-aliphatic) and aryl esters and halfesters, acid halides and ammonium and amine salts. The glycols may be, for example, ethylene, trimethylene, tetramethylene, hexamethylene or decamethylene glycols. The preferred material is polyethylene terephthalate. The filaments, produced by forcing a filtered melt of the material through spinnerets, may be drawn in the solid state preferably at temperatures exceeding 60‹C. and at least 30‹C. less than the melting point. They may then be subjected to a heat setting and relaxing treatment by heating at or above the drawing temperature but at least 30‹C. below their melting points, under a tension permitting a limited shrinkage, while yarns consisting of bundles of continuous drawn filaments twisted together may have the twist set by heating at such a temperature under a tension which does not stretch the yarn but prevents unlimited shrinkage. Staple fibres may be produced by cutting or breaking the filaments, preferably after crimping. The composite yarns may be made into braided, knitted or woven fabrics. Specifications 533,307, 536,379. 536,380, 578.079, 590,451, [all in Group IV], and 603,840, [Group IV(a)], are referred to.

Abstract: 1,184,735. Crimping wool sliver. DAIDO KEORI K.K. AND G.K.K.A. KENKYUSHO. 5 March, 1967 [5 March, 1966], No. 9170/67. Headings DIF and D1W. A keratinous fibre sliver, e.g. of wool, is twisted to avoid fibre slippage which would otherwise occur upon stretching, stretching the sliver, setting the stretched sliver and untwisting the sliver. The setting step can be performed in a water bath comprising specified setting agents. The sliver can be treated with liquid or vapour prior to setting, the sliver may be stretched prior to, during, or after setting. The sliver can be dried after setting with the sliver twisted or untwisted. The drying operation can be carried out with or without a stretching of the fibres. The keratinous fibres may be mixed with other natural or synthetic fibres. The sliver can be plyed with one or more other slivers of keratinous slivers, during treatment. The sliver twist and ply twist may be in different directions, the plied slivers may result in different amounts of stretch occurring in different parts of the sliver. The sliver produced may be released to produce an even crimped bulked sliver. If a variably stretched, then upon relaxation the sliver will become variably crimped.

Abstract: 1,043,542. Cam-operated switches. M. INGRAM. March 8, 1963 [Sept. 28, 1962], No. 9356/63. Heading H2B. [Also in Division G1] A micro-switch 238 is operated by rotation of a cam-plate 300 which is freely mounted upon a shaft 62. A pusher arm 304, rigidly fixed to shaft 62, can move through nearly 360 degrees in an anti-clockwise direction from a datum position against stop 310 and does not then move cam-plate 300. After returning to the datum position the pusher-arm can rotate nearly 360 degrees in a clockwise direction and carries cam-plate 300 with it. Upon movement of cam-plate 300 roller 309 is forced out of a notch 306 in the cam-plate and arm 308 operates the micro-switch. This allows a spring- biased arm 301 to pivot about pin 302 so that shoulder 303 engages with pusher arm 304, holding it against stop 310. The pusher arm is not released until the shaft returns to its datum position and roller 309 falls into notch 306. Thus switch 238 is controlled by movements of shaft 62 over nearly 720 degrees, being closed over one half of the range and open over the other half.

Abstract: 766,034. Floor treating machines. LALONDE, F. P. March 31, 1955, No. 9417/55. Class 138(1) A rotary floor treating machine for scrubbing, waxing, polishing or like treatment of floors, comprises a vertical motor shaft 6, Fig. 1, a driven pulley 16 axially aligned with the shaft 6 and carrying a floor treating work disc 33, a countershaft 13 arranged in parallel relation to the shaft 6 and the axis of pulley 16, a drive belt (or belts) 11 connecting the shafts 6, 13, a second drive belt (or belts) 15 connecting the countershaft 13 and pulley 16, and means for connecting the countershaft 13 for rotation about its own axis and for swinging movement toward and away from the shaft 6 and pulley 16, the mounting means including resilient biasing means normally tending to swing the countershaft away from the shaft 6 and pulley 16. The machine construction and operation is generally the same as that described in Specification 746,802. Referring to Figs. 2 and 3 the countershaft 13 is rotatable in a bearing 39 carried in a socket 36 on a lever 34, one end of the lever being pivoted on a pin 35 to the machine casing 8, whilst the other end is provided with a swivable block 42. A hole 46 is provided in the block 42 and a rnd 44 passes through the hole, one end of the rod being threaded to receive a nut 48 and the other end having a head 45 mounted for angular movement in the casing 8. A compression spring 47 is disposed between the nut 48 and the block 42. Rotation of the rod 44 in one direction relative to the nut causes the spring compression to increase whereby the lever 34 is urged to the right in Fig. 2, and thus the belts 11, 15 are tightened on their respective pulleys. Rotation of the rod 44 in the opposite direction causes the tension in the belts to be released. The casing 8, Fig. 1, is provided with an opening having a cover 50. When the tension of the belts is relieved and the cover 50 removed the upper belts 11 may be removed from the motor shaft pulley 10 and dropped in a chamber 51 formed above the fixed trunnion 19 for the pulley 16; thereafter the belts 11 may be removed through the casing opening, The lower belts 15 may be removed from the bottom end of the casing 8 after the work disc 33 has been removed from the pulley 16.
