Title: Improvements in or relating to the manufacture of blasting explosives
Inventor: REID THOMAS JAMES
IPC: C06B21/00
Filed: 1956-07-02
Abstract: 800,442. Blasting explosives. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Feb. 8, 1957 [July 2, 1956], No. 20386/56. Class 9(2) A blasting explosive of the kind comprising a solid inorganic oxidizing salt coated with a fusible organic fuel is prepared by dispersing particles of the oxidizing salt in a stream of hot air and heating them by means of said stream to a temperature above the fusion point of the organic fuel and directing the thus heated particles in the substantial absence of said stream into and mixing them with a stream of said fusible organic fuel in molten condition. The inorganic oxidizing salt is preferably ammonium nitrate or a nitrate of an alkali or alkaline earth metal such as sodium, potassium, barium, calcium or magnesium. Specified fuels include 2.4: 6-trinitroluene, a molten dinitrotoluene, a mixture of di- and/or trinitrotoluenes solid at ordinary temperatures or paraffin wax. Apparatus for carrying out the process comprises a fan heating means for heating the current of air, a duct, a solidgas separator, preferably provided with a vibrator, means for the continuous supply of oxidizing salt and continuous mixing means wherein said fan permits heated air to enter said duct, the duct leading to the solid-gas separator, which in its turn leads to the mixing means. In an example, spray dried ammonium nitrate granules are fed through a vane feeder 2 acting as an air seal to a pulverizer 3 provided with a fan. The granules are carried into and through the pulverizer by a -stream of hot air which is heated by heater 4. The hot air stream carries the pulverized ammonium nitrate via pipe 5 into a cyclone separator 6 vibrated by a vibrator 7. The salt emerges through a rotary vane feeder 8 acting as an air seal into the mixing means 9 containing molten trinitrotoluene. The coated particles drop into a cooled mixer 11 in which the coating solidifies. Specification 626,067 [Group II] is referred to.

Title: Improvements in electrical insulators
IPC: H01B17/14
Filed: 1932-09-29
Abstract: 408,225. Insulators. ROST, H., P.O. Box 1815, Mexico City. Sept. 29, 1932, No. 20638/31. [Class 36.] An insulator comprising a shell adapted for attachment to a support and having one or more skirts is made of a synthetic thermoplastic organic compound containing plasticizers but which does not contain hydroxyl or which has had part of its hydroxyl removed, such compound consisting, for instance, of polymerization products of acetylene, acrylic acid, styrol, vinyl ethers, vegetable oils, cyclic ketones or methylated ketones ; or of condensation products of the above polymerized materials with an aldehyde. The insulators may be moulded in one piece or may consist of several separate parts which are secured together by the application of a solvent. Fig. 1 shows a supporting insulator mounted on a screw-threaded pin 11 and comprising thin shells A, B, C which are cemented together at 9, 10, 12. The conductor to be supported is carried in a groove 7 in the shell C. In other constructions the lower part of the shell C may have a metallic coating or may connect with the skirt 5 of the shell A, or the shells B, C may be spaced by a grooved intermediate shell. In these constructions the shells may be of a composition consisting of polystyrol and tricresyl phosphate, with or without natural shellac, or the composition may be a mixture of polyvinyl acetate and triphenyl phosphate. As shown in Fig. 5, a suspension insulator comprises several shells, consisting of screw-threaded sleeves 1 witli skirts B, which are screwed into one another and to suspension means D, E, as shown. Fig. 6 shows another construction in which a number of shells, comprising sleeves 1 and skirts B, are mounted on a support E to form a supporting insulator, the sleeves either being closed at one end and screwing into one another or being open at both ends and screwing on an insulating tube F, as shown respectively at the left and right hand sides of the Figure.

Title: Improvements in or relating to electromechanical oscillators
IPC: H03H9/24
Filed: 1964-05-20
Abstract: 1,073,962. Electromechanical oscillators and filters. SIEMENS A.G. May 20, 1964 [May 21, 1963], No. 20712/64. Heading H3U. A mechanical resonator of electrostrictively inactive material carries one or more piezo - electric crystals in a slot therein which does not extend beyond the neutral axis of the resonator and lies predominantly in a region bounded by two adjacent nodes of oscillation. In Fig. 1 a steel bar 105 carries in a slot a piezo crystal (e.g. lead zirconate) 106 bounded by silver electrodes 108, 109 and an insulating material 110, e.g. quartz glass, both being on one side of the neutral axis 13. A polarizing voltage is applied to the silver electrodes by leads 116, 117, the latter being at an oscillation node 8. The resonator is mounted by connections 11, 12 at the nodes, which also serve for coupling to further resonators in a multi-stage filter. The crystal and plate 110 can be attached to the bar by coating with metal and then soldering, or by shrink-fitting as the bar cools down. In a modification (Fig. 3, not shown), the glass plate is replaced by a second piezo crystal polarized in a direction opposite to the first so that the alternating stress imparted to the bar by the two crystals act to reinforce one another. Such a pair of crystals may be incorporated in a tuning fork in one or both of the arms, between the prongs (Fig. 6, not shown) or in a slot at the base (Fig. 7, not shown). In the last-named case the system may be operated as a quadripole by including an insulating material such as quartz glass between the crystals (Fig. 8, not shown). Depending on the mutual polarization directions of the crystals the input and output signals are either in phase or antiphase. More than two crystals may be incorporated in the slot (Fig. 9, not shown). In another form (Fig. 10, not shown) the polarizing voltage is applied at right angles to the axis of the resonator to use the transverse piezo-electric effect, and this may be applied to the tuning-fork type as well. The resonator may be of steel or quartz glass and may be of rectangular or circular cross-section. There may be two separate slots carrying crystals, on the same side of the resonator, or opposite one another, or staggered (Fig. 4, not shown).

Title: Improvements in or relating to stop motions for spinning, doubling and twisting, andlike textile machines
IPC: D01H13/18
Filed: 1930-07-08
Abstract: 358,937. Broken-end stop motion for spinning, twisting, and like machines. MACKIE & SONS, Ltd., J. and MACKIE, J. P., Albert Foundry, Belfast. July 8, 1930, Nos. 20720 and 35247. [Class 120 (ii).] Spinning, twisting, and doubling machines are provided with a detector or feeler member which is not an essential part of the machine and which can be set either in an operative position, so that on yarn or roving breakage it is acted upon by a power driven actuator to stop the feed, or in an inoperative position in which it is clear of the yarn and does not affect the running of the machine. The power driven actuator may automatically move the detector into inoperative position after stoppage. The pressure exerted by the feeler on the yarn is adjustable. The yarn 1, Fig. 1, passes from the bobbin 2 to feed rollers 4, 5, delivery rollers 8, 9, and to the flyer 10. The detector member 17, 18 is pivoted at 20 to a vertically movable bar 21. The arm 17 is normally engaged by the yarn 1, but on breakage, the feeler rotates about the pivot 20 until its. hooked upper end is engaged and lifted by the oscillating arm 27. This raises the bar 21 so causing its projection 30 to displace the feed roll 4 and stop the feed, and the member 35, pivoted on the bar 21 at 31, to rotate and clamp the yarn against the rail 34, Fig. 3. On the downward movement of the oscillating arm 27, the detector member 17, 18 is rotated back through its original position into an inoperative position in which the arm 17 is clear of the yarn. The member is retained in this position by dropping slightly so that the pin 38 on the vertical bar 21 engages the recess 39 in the slot 37. The machine is restarted by pulling down the lever 32, this releases the yarn and lowers the bar 21 to its original position whereby the feed rollers 4, 5 are allowed to come into contact. The machine continues to function with the stop mechanism inoperative, and when the tension in the yarn builds up, the detector member 17, 18 is lifted by hand until the recess 39 clears the pin 38, and is allowed to swing forward until it contacts with the yarn. The detector member carries adjustable counterweights 40, and is retained in position on the pivot 20 by a spring clip 45. The arm 17 is independently pivoted at 19 so that it can swing in a clockwise direction only ; this permits of the removal of the back delivery roller 8 from the ledge 22, and then towards the front of the machine for cleaning purposes. In a modification the oscillating arm is replaced by a continuously rotating disc 50, Fig. 9, carrying pins 51. On yarn breakage the detector member 18 swings into the path of the pins 51, whereby the member 18 and bar 21 are lifted, the yarn clamped and the feed rollers separated. The next pin 51 engages the face 53 on the detector member 18 and rotates the latter in the reverse direction into inoperative position. Specification 337,529, [Class 120 (ii), Spinning, twisting &c.], is referred to.

Title: Textured synthetic multifilament yarn and a method of manufacture thereof
IPC: D02G1/02
Filed: 1973-05-02
Abstract: 1431568 Bulking, twisting and testing yarns; finishing woven fabrics MITSUBISHI RAYON CO Ltd 2 May 1973 20794/73 Headings D1F D1K D1S and D1W A synthetic e.g. polyamide or polyester, multifilament textured yarn, which has sufficient potential torque for producing a fine crepe fabric therefrom, comprises a number of bulky portions between adjacent compact portions. The latter are randomly developed along the length of the yarn and consist of a number of twisted individual filaments compactly combined and the former each consist of a number of crimped individual filaments independent from each other and having an opposite twisting direction of the multifilament yarn from the twist direction of the adjacent two compact portions. The yarn is formed by false-twisting a synthetic multifilament yarn in an overfeeding condition at a temperature within a range between the softening and melting temperatures of the filaments. Additional twist e.g. 500 turns/metre in the same direction as the false-twisting may be applied to modify the torque characteristics of the yarn. As described, polyester yarn of 75 denier 24 filaments is overfed 2% to falsetwisting at 3390-4200 turns/metre at a temperature of 240 or 245‹C and overfed 4% to wind-up: polyamide yarn of 120 denier 30 filaments is overfed 1% to similar false-twisting at a temperature of 210‹C and wound at 5% overfeed. In apparatus, Fig. 9 (not shown) for assessing the yarn, the torque of a vertically suspended specimen length thereof is allowed to deflect a thin vertical resilient rod the indicated or recorded "free length" or "breaking length" of which is used, in a manner described, to calculate the yarn torque. Plain weave fabric with yarns of the invention in warp and weft partly with double picking (and using both S and Z false-twisted and modified textured yarn) are wet treated with mechanical vibration under relaxed conditions to release the potential torque of the yarns and therefore develop fine crisp crepes (and consequent shrinkage of the fabric). Then the fabric is subjected to tentering and heating so that the crepes set, dyeing and finishing.
