Abstract: 661,041. Angular bending. REDMAN TOOLS & PRODUCTS, Ltd., and REDMAN, A. M. March 24, 1950 [Dec. 24, 1948], No. 33265/48. Class 83 (iv). In a machine for bending and shaping strip &c. metal a stationary former 16 is secured to a bridge member 15 and a frame 23 on a fulcrum 22 carries a fluid cylinder 34 acting through a roller 42 on the back of a sliding die 37 supported on the frame to press the work-piece on to the former. In order to traverse the die 37 about the former the position of the fulcrum 22 is varied by two fluid cylinders 26 positioned at right angles to one another and with rams 28 hinged to the fulcrum. The operation is started with the work-piece clamped to the former and the fulcrum in position 53, Fig. 4, and pressure is applied by the cylinder 34 to profile the workpiece. By manipulation of the cylinders 26 the fulcrum is shifted from position 53 to position 55, the frame gradually swinging from position 52 to position 56 to allow the die 37 to shape the work-piece with an ironing action. The machine is then reset and the further shaping is completed in three more stages. Pressure on the die 37 may be varied when producing forms of non-uniform section by a cam rotating with the frame 23 controlling the valve of the cylinder 34. The fulcrum cylinders may be controlled by cams rotating with the frame. Specification 665,560 is referred to.

Title: Improvements in gas blast electric circuit interrupters
IPC: H01H33/873
Filed: 1954-11-17
Abstract: 758,505. Gas-blast switches. GENERAL ELECTRIC CO. Nov. 17, 1954 [Dec. 10, 1953], No. 33323/54. Class 38(5) [Also in Group XXIX] A gas-blast circuitbreaker comprises two series breaks 25, 26 formed by pairs of nozzle and rod. contacts 32, 30 and, 33, 31 respectively, mounted in a pressurized casing 11 which is vented to atmosphere at 60 through an outlet blast valve 61, the breaks being bridged by movable pivoted contacts 34, 35 held closed by a spring 55. The contacts and the valve 61, are interconnected by a pneumatic coupling 65 comprising a cylinder 66 having two pistons 67, 68, the former being secured to, and actuaated by, the crosshead 51 by which contacts 34, 35 are actuated, and the latter being secured to the valve 61. As crosshead 51 moves downwards to open the breaker, consequent downward movement of piston 67 reduces the gas pressure between the pistons and thus establishes a pressure differential on piston 68, the space above which is at the pressure of housing 11 due to an aperture 71 which causes piston 68 to movedownwards and open valve 61, the movement of the valve and piston being arrested when the former engages a resilientlymounted stop 75. The breaker is latched in the open position by means not shown; but valve 61 is reclosed by spring 64 either during the opening stroke or as soon as this has been completed, when a bleed passage (Fig. 3, not shown) in piston 68 produces equalization of pressure on the latter. A check valve (Fig. 3, not shown), in piston 67 allows rapid closing operation. In another embodiment (Fig. 4) a port 80a is provided in casing 66 above the lowermost position of piston 67 at the end of the opening stroke, so that as piston 67 passes this port the pressure differential on piston 68 is instantaneously reduced and the valve reclosed under influence of spring 64. In yet another embodiment (Fig. 5) the piston 91 acts as the driving piston for opening the breaker contacts when a fault-responsive valve 92 opens the cylinder 89 to atmosphere, while the breaker is closed when valve 92 is turned back so that conduit 96 is connected to supply 88 the contacts being held closed by a spring 55 as before. The breaker is held open by air pressure on piston 91 causing engagement of an annular projection 97 with the cylinder 89.

Abstract: 755,626. Glass fibres. SCHULLER, W. (Schuller, W.). July 14, 1954 [Dec. 7, 1953], No. 34038/53. Class 56 A process and apparatus for producing endless threads and short staple fibres from materials such as glass comprises drawing off material in the liquid or molten state by mechanical means in a continuous operation into the form of rods, the rods then being heat-treated and drawn off continuously into fine threads for further treatment as desired. A muffle 1, heated in any known manner, has a tuyere plate 2 provided with three rows of drawing-off openings each of diameter greater than 5 mm. Glass rods 6a, 6b, 6c are drawn off through these openings by a pair of rollers 4, 5, the three sets of rods being brought into one plane in the zone of the rollers, where the rods 6 are kept separate by comb-shaped plates 9, 10. Cooling means 7, 8 such as pipe lines, may be provided. Adjacent the second plate 10, the ends 11 of the rods 6 are melted by melting means 13 to form threads 12 which are drawn off by a cylinder 14. The drawing rollers 4, 5 are at a distance of about 30 cms. from the tuyere plate 2 and their speed is such as to produce rods 6 of between 1.5 and 2.5 mms., the speed of the drawing-off cylinder 14 being regulated to produce threads 12 of the required thickness. The rollers 4, 5 may have a coating of asbestos or silicon-rubber to protect them and form a gripping surface. The melting means 13 may comprise two rows of electric coils installed in a burner device at about 9 mm. apart either side of the rod ends 11. The rollers 4, 5 and melting means 13 are preferably movable apart to allow the rods 6 to project freely when the apparatus is started. The glass threads 12 are, as shown, removed from the cylinder 14 by a scraper 16 and converted into short staple fibres 17 which are passed by a guide 18 on to an air-pervious conveyer belt 19. A cylinder 21 below the cylinder 14 rotates at a slower speed than the cylinder 14 and may be used when the apparatus is just started, to seize and draw off the rods 6 until they reach the required diameter, when the rollers 4, 5 and melting means 13 are brought into operation. To assist in maintaining the liquid mass in the muffle 1 at an even temperature, the rods 25, which may be of 10 mm. diameter, are fed horizontally from an inclined slide 26 by a roller 24 into grooves 24a rotating slowly to pass the rods 25 one at a time to a slide 27 and then through a shaft 28 into the liquid mass.
