Abstract: 1,012,750. Extruding. LOEWY G.m.b.H. PRESS-UND WALZANLAGEN. Aug. 28, 1964 [Sept. 9, 1963], No. 35412/64. Heading B3P. An hydraulically operated metal extrusion press has its main cylinder 16 supplied with low pressure liquid for performing an approach stroke and when resistance to movement increases the low pressure supply is cut off and a supply of high pressure liquid is started automatically to perform the extrusion stroke. Low pressure water is supplied from an accumulator 20 through spring-loaded pre-fill valve 24 until the stem 10 is stopped by engagement with billet 4. Flow of water then stops and valve 24 closes, whereby its extension stem 32 trips a limit switch 28 or a magnetic coil to start the high pressure supply. Alternatively, the latter may be started when the supply of low pressure liquid through a flow meter ceases. A spindle 34 operated by a piston 36 is controlled automatically or manually to open the valve 24 during retraction of the stem.

Nov. 27, 1930, No. 35751. Convention date, Nov. 27, 1929. [Class 38 (v).] Arc-rupturing devices.-The arc formed on separation of a contact 6 from a fixed contact 3 is driven by a blow-out coil 5, having poles 24 and a core 25, into a passage formed by insulating walls 28 between extensions 26 of the poles 24. Plates or discs 27 of conducting material of progressively-decreasing size are assembled in slots in the plates 28 for the purpose of subdividing and cooling the are as it travels outwards. Two series of plates, as shown, are provided for high-tension working, but the lower one may be replaced by a conducting wall for use with lower tensions. In a modification, Fig. 3 (not shown), a longitudinally guided rod carries a bridging-contact, which is driven piston-like along the passage and helps to draw out the are and drive it into the plate structure. The movable contact 6 is pivoted at 7 and controlled by an opening spring 8. On a predetermined overload occurring, the series coil 12 moves its guided core 13 to the left against the action of a spring 15 thereby moving a latch 9, having a pin-and-slot connection with the core 13, to the left and allowing the contact 6 to move to its open position. At the same time a toggle 16 is broken under the action of a spring 19 and allows a lever 21 to rotate clockwise about its pivot 22 and lower the latch 9 to which it is pivoted at 23. The pin-and-slot connection allows the latch 9 to move far enough to again come under the contact 2 ready for reclosure. To reclose, a coil 18 is energized to extend the toggle 16 to the dead-centre position, whereupon the spring 15 carries it into the overset position shown.

Abstract: 1,211,920. Filled resinous composition. MONSANTO CO. 29 July, 1968 [30 Oct., 1967], No. 36121/68. Headings C3B and C3R. Compositions comprise a resinous matrix with reinforcing filler particles dispersed therein. A first thermosetting resin completely envelops the filler particles and second thermosetting resin surrounds the enveloped particles and is integral with the first resin composition. The modulus of elasticity of the second resin composition is greater than that of the first. Both resins may be epoxy resins, e.g. polyglycidyl ethers of bisphenol A. The first resin may contain a flexibilizer, e.g. a saturated polyester. Suitable fillers are glass fibres, glass microbeads, silicon carbide or silicon nitride whiskers. The compositions may be prepared by dispersing the filler particles in solution of resin in the " A-stage " thermosettable state in a solvent in which it is not soluble in the " B- stage " and which provides a hydrogen donor. A curing agent is then added which advances the resin to the " B-stage " whilst stirring. The enveloped particles are then separated from the reaction mixture. A suitable solvent for a flexibilized epoxy resin is a mixture of water, a lower alkanol and a lower aliphatic ketone. The enveloped particles may then be added to a solution of the second resin. Drawings (not shown) illustrate the dispersion of the enveloped filler particles in the resin matrix.

Filed: 1929-11-28
Abstract: 337,636. Folliet, A., and Sainderichin, N. Oct. 19, 1929, [Convention date]. Distilling zinc and other metals.-Volatile metals contained in zinciferous ores containing sulphur are extracted by blowing air at 650- 800‹C in two stages on to a thin travelling layer of the ore, first on to the ore alone, when the sulphur is removed, and then on to the hot roasted product plus reducing carbon. In one form of the invention the ore, charged from automatic distributors with adjustable discharge outlets through a hopper C traverses a rotary drum to the part F where it is roasted by blast from jets t of a main tuyere T. The roasted products and reducing carbon from a hopper R pass under jets t' to volatilise the metals which pass into a chamber D with the products of combustion while the residues are automatically discharged into a chamber S. Two independent tuyeres may be employed, or the roasting and distilling may be performed in two separate furnaces. Specification 312,667 is referred to.

Abstract: 782,752. Flaw detection by nuclear radiation. ROLLS-ROYCE, Ltd., and UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Dec. 19, 1955[Dec. 17, 1954] No. 36658/54. Class 40(3). In order to test a flexible hose, made, for example, of rubber, for cracks or flaws the hose is filled with liquid containing a radio-active isotope in solution and under pressure, it is then emptied, rinsed and moved past a radiation sensing device to detect any parts having abnormal radio-activity. A suitable isotope combination is cerium 144-praseodymium 144 and the test solution may be made up in the proportions of 7 millicuries of this in 200 c.c.s. of redistilled water containing a minimum of 20 micrograms per c.c. of inactive cerium and praseodymium as carriers. Apparatus for effecting the test may comprise a drum 11 on which the hose 10 can be mounted with its ends connected by tubes 12 and 13 to mechanically coupled rotary valves 14 and 15. These valves are coupled to a reservoir 28 for the test liquid, a pump 36, a source of water 30, and a drain pipe 38. They have four positions : in the first the pump forces test liquid through the hose, in the second the pump continues to force in liquid but the far end of the hose is closed by a pressure gauge so that the required pressure is reached inside the hose; in the third valve position both ends of the hose are opened to drain the test liquid back into the reservoir 28, and in the fourth water from source 30 is allowed to flow through the hose to the drain to rinse it. The hose now has a small residual radioactivity and greater activity at any points where cracks or flaws retain some of the test liquid. To locate such flaws the hose is wound slowly from drum 11 past a test position to a further drum. At the test position the hose 10 passes through an array of geiger-muller tubes 42 the output of which is fed through a cathode-follower circuit CF to a rate-measuring circuit RM. The circuit R.M. feeds a potentiometer recording apparatus P continuously recording the level of radiation emission on a paper chart and also a solenoid operating a marking pen. The pen may either be arranged to mark continuously except when the emission exceeds a certain value or to mark only when such emission occurs. In either case the defective portions, if any, of the hose can readily be located.
