Title: Improvements relating to the manufacture of explosive and propellent compositions
IPC: C06B21/00
Filed: 1958-05-16
Abstract: 893,277. Explosive and propellent compositions. POUDRERIES REUNIES DE BELGIQUE S.A. May 16, 1958 [Dec. 13, 1957], No. 15847/58. Class 9(2). A process for the production of pourable explosive or propellent compositions containing at least one fluid component and at least 50% by weight, calculated on the total weight of the composition, of a pulverulent or crystalline explosive component comprises treating the surface of the pulverulent or crystalline component with a glycol. Preferably 0.1 to 2.5%. by weight of ethylene glycol or a polypropylene glycol is sprayed or atomized on to the crystalline or pulverulent component in the moist state and the product is subsequently dried. In Examples (1) 0.5% of polypropylene glycol is added to hexogen and trinitrotoluene, and (2) ethylene glycol is added to ammonium perchlorate containing lecithin, dioctyl phthalate, and an unsaturated polyester. Acrylic polymers, epoxy resins and polysulphide elastomers may also be used as binders.

Title: Power tools
IPC: B27B17/12
Filed: 1972-04-06
Abstract: 1338368 Lubricating SKIL (NEDERLAND) NV 6 April 1972 [15 April 1971] 15986/72 Heading F2A [Also in Division B5] A power tool, e.g. a chain saw, which has a compartment which is pressurized during operation has a lubrication system which functions as a result of the pressure in the container during operation, and which has means for effecting manual lubrication prior to operation. The lubrication system has a closed reservoir which is connected by a passageway to the compartment so as to be pressurized during operation. The reservoir has a second passageway which leads to the moving parts of the tool. A valve is located in the second passageway and has biasing means which tend to close the valve but which allow the valve to be opened by the lubricant during flow. Manually operable elements are located in the second passageway which are capable of opening the valve and pumping lubricant to the moving parts. As described the pressurized compartment is the crank-case of the internal combustion engine which drives the saw. The valve and means for effecting manual lubrication may be combined in a cylinder 33 which is located in the reservoir. Lubricant passes through a filter 55 and displaces a ball 62 of the. valve and then flows through a restricted passage 57 to a duct 83 from which it passes to the chain. Lubricant may be pumped manually by piston which is operated via links by a push-button located on the handle of the saw.

Title: Improvements in circular knitting machines and in methods of knitting on the same
Inventor: GREWCOCK SIDNEY BERNARD
IPC: D04B35/00
Filed: 1969-03-27
Abstract: 1,248,842. Knitting machines. BARBER & NICHOLLS Ltd. 13 March, 1970 [27 March, 1969], No. 15991/69. Heading D1C. A multifeed circular knitting machine having a rotary needle cylinder in which movable thread guides are provided to feed or withdraw elastic yarns and a yarn severing device and a suction clamping tube are provided comprises means for temporarily rendering inoperative a knife element of the yarn severing means thereby enabling an elastic yarn to be carried past the knife element to an extent greater than the distance between the thread guide and yarn severing device with direction of rotation of the cylinder rotation during which extra travel the temporarily inoperative knife element is restored to its operative position. In an eight feeder machine movable yarn guides 11', 12 are provided at each feed and are provided at each feed under the control of a pin drum 12 having pins 13 which drum is racked by a pawl 16 and ratchet 15 under control of a Bowden cable 20. When an elastic yarn is taken out of action under control of drum 12 a saw 30 with teeth 30a mounted on the melting dial carries the yarn ET around a pin 44 under the end of suction tube 32 and past a yarn severing device having a movable blade 31 which normally co-operates with teeth 30a to sever the yarn but which is temporarily rendered inoperative by a Bowden cable 41 under control of a cam drum. The elastic yarn is as stated carried past the movable blade without severing and is wound around pegs 45, 46, 47, 48, 49, 44 and 45 in that order during which period the cam drum returns the blade 31 to the operative position and the yarn is severed. After severing and relaxation of the elastic yarn it is then of sufficient length to be accurately caught and held by the suction tube 32 in the position ET' after it has unwound from around the pegs. The introduction of elastic yarn is only made at selected feeds for example to introduce the yarn at every third course and knitting it in at every other wale to produce an elasticated waist band in a pair of tights. To achieve this needles are provided having either long, medium or short butts B<SP>1</SP>, B<SP>2</SP> or B<SP>3</SP>. The long butts provide the knitted elastic stitches, the medium butts the tuck stitches for engaging the start of the yarn in the fabric and the short butts to miss completely. A bolt cam 50 is provided which lifts the butts B<SP>1</SP> to clearing height against the stitch cam 51, the butts B<SP>2</SP> to tuck height TH and allows the butts B<SP>3</SP> to pass completely thereover to miss altogether.

Abstract: Synthetic rubber-like materials of the type manufactured by polymerizing butadiene, its homologues or substitution derivatives, either alone or in combination with other polymerizable substances such as styrene and acrylonitrile, are plasticised by masticating under heat a mixture of the synthetic rubber, a plasticising agent for natural rubber and a carboxylic acid of the non-soap-forming type.  It is preferred to carry out the mastication at a temperature between 100 DEG  and 140 DEG  C., and to use benzoic or acetic acid as the acid and mercaptobenzthiazole as the plasticising agent.  The materials may be mixed and masticated on mill rolls or in an internal mixing machine, or the synthetic rubber may be steeped in a liquid consisting of or containing the acid, and the plasticiser incorporated into the treated synthetic rubber.

Abstract: 140,127. Motte, L. C. Oct. 10, 1918. Hulls; ships supported on separate floats. - Sheet-metal hulls of seaplanes, hydro-aeroplanes, and boats, floats, &c. are formed in sections meeting both upon horizontal and vertical planes, by stamping, cutting, pressing, or rolling, the sections being then joined together. Various methods of jointing contiguous edges of the plates by riveting, welding, &c. are described by way of example. Figs. 15 and 19 show a seaplane body made of plates united along the gunwale 8, and along a vertical longitudinal plane, by means of flanges 9. Keels 10 are formed in the underside, and the portion between these keels may constitute a hydroplaning surface, as shown in Fig. 19. Fig. 26 shows a section of a boat formed of plates shaped as shown in Fig. 22, the dotted lines indicating an horizontal division, and the vertical joint being formed by uniting the inner edges 13 to form the keel, and the outer edges 14 to form the covered-in parts at the ends of the boat. The vertical jointing planes may be transverse. One method of jointing the edges of the plates to form a keel is shown in Fig. 1, in which the plates are flanged at b and united to a stiffener bar a; or the stiffener bar may be constructed to embrace the flanges b; or the stiffener bar may be omitted and one flange b be made longer than the other, so that it may be bent into U-form to embrace the other flange b. Fig. 2 shows curved flanges e embraced by similar flanges g, h formed on a stiffener bar f. In Fig. 5, L-shaped flanges p are enclosed by a capping-piece q; or one flange n may be bent round the other flange m as shown in Fig. 7, with or without an interposed strip u; or the plates may enter between flanges r, s, Fig. 6, of a member t, or between flanges formed by a Z-shaped strip. Fig. 8 shows flanges b united to members v, w. In Fig. 12, one plate is shown entering a bevelled rabbet f in the other plate, and the latter may be formed with a pocket d<1> containing a wood or other filling b<2>. Fig. 13 shows a method of uniting the plates at the bow end by means of a member c<1>. In Fig. 14, one plate b<1> is bent into Z-form to provide a recess to receive the edge of the other plate b; the plate b<1> may be formed with a bead b<4>, in which case the other plate b is then bent around the bead as at y<1>.
