Title: Improvements in or relating to sheet metal bending or cupping tools
Inventor: COUPLAND ERNEST
IPC: B21D22/02
Filed: 1954-02-06
Abstract: 757,634. Bending and cupping dies. RUBERY OWEN & CO., Ltd. Feb. 2,1955 [Feb. 6, 1954], No. 3556/54. Class 83 (4). A sheet metal bending or cupping tool including a movable forming punch and a facing concavity of a die is characterized in that the forming punch comprises two separate members, namely, a punch nose to coact with the die to form the metal sheet into channel, trough or other concavity with upstanding edges and a punch body for bearing on the upper faces of the edges of the pressing at an appropriate pressure during the latter part of the forming operation whilst the punch nose partially withdraws into the punch body. The die 10 is secured to the press bed 11 and is provided with a mechanically, pneumatically or hydraulically operated ejector 12. A vertically reciprocable press ram 13 carries a bolster 9 to which is detachably bolted the punch body 14, and the punch nose 15 is slidably mounted for limited vertical movement in the body 14. The nose is held extended from the body 14 during the initial part of the forming operation by hydraulic pressure on a piston 17 which acts on the nose through a sleeve 18. A stripper 19 is arranged coaxially in the punch nose 15 and is hydraulically operated by a piston 20. In operation the stripper 19 first engages the blank 23 and holds it in position until the nose 15 begins the forming operation. Finally the punch body 14 travels downwardly (Fig. 3) and its operative face 25 engages the upper faces 24 of the edges of the formed blank 23a whilst the nose withdraws into the punch body. This pressure on the upper faces neutralizes the stresses which might otherwise cause distortion of the pressing. On withdrawal of the ram the stripper 19 removes the pressing from the punch. Alternatively, the punch nose and stripper are operated pneumatically or by a spring and the operative face 25 of the punch body is bevelled.

Filed: 1975-01-28
Abstract: 1470621 Endless chain conveyers; roller conveyers VULCAN ENG CO 28 Jan 1975 [14 Feb 1974] 3584/75 Heading B8A [Also in Division F4] Bricks for lining a metallurgical vessel are moved vertically on a conveyer mounted on a tower depending within the vessel (Fig. 1) to a second horizontal conveyer at an adjustable height and the second conveyer is adjustable to move the bricks to container wall. The first conveyer comprises two pairs of endless chains 28, 30, running in the same plane on the return run, and below the adjustable discharge point, but spaced apart on the upper part of the down run so that folding pallets 46 lie horizontally between rods 51 secured to the chassis. To prevent interference on the return run, the inner pair of chains 28, Fig. 7, have U-shaped links 47 to allow passage of the rods 51 secured to the outer chains 30. The sprockets 31 around which the chains 28 run have spaced teeth to avoid interference from the links 47. A frame 44, Fig. 2, adjustable in height by cables 49, carries sprockets on shafts 45, 40 and 42 around which chains 28 run to carry one end of the pallet horizontally and then rearwardly to the lower part of them. The other end of the pallet is carried by chains 30 round sprockets on shafts 38, 40 and 42 so that it is folded at the lower part of the run. The second conveyer 54 is mounted on the frame 44, the outermost rollers 64, 66 and an adjusting roller 68 being movable by a rack and pinion operated by crank handle to adjust the horizontal extent of the second conveyer belt 56. Bricks are delivered to a pallet at the top of the tower from tilted roller tables 86, Fig. 6, which rotate faster than the slowly rotating tower and conveyer. A delivery roller way 84 transfer bricks over a control roller way to tables 86, which are provided with cam operated gates so that bricks are only delivered when a tube 86 is preferably aligned with a conveyer pallet 46. An incline with rollers 94 guides each brick through a gap in a raised shoulder 90 surrounding the inner edge of the table 86 and secured to the tower in alignment with the conveyer. The control roller way 98, Fig. 11, comprises driven rollers 100, free rollers 101 and rollers 102 liftable by a pneumatic cylinder. Photo-electric sensors 106, Figs. 8 and 12, co-operate with mirrors 108, Fig. 12 on the tables 86 so that as an empty table 86 approaches the control conveyer the rollers 102 are lowered to enable the driven rollers 100 to feed a brick to the table 86. A gate 110 on each table 86 is lowered only when the table reaches the gap in the shoulder 90, and carries a shutter 112 which blocks the mirrors 108 when the conveyer 84, control conveyer 98, table 86 and pallet 46 are aligned to prevent a brick being fed directly from conveyer 84 on to a pallet to cause jamming. A sensor 114, Fig. 11, controls the pneumatic cylinder to lift the rollers 102 when a brick has been fed from the control conveyer 98 to prevent a brick fed by gravity from the supply conveyer 84 passing directly over the control conveyer 98.

Abstract: 818,482. Resistance measuring. EVER SHED & VIGNOLES Ltd. Feb. 8, 1956 [Feb. 16, 1955], No. 4682/55. Class 37. In apparatus for measuring earth resistance, in which the current supplied to an earth circuit is maintained at a predetermined ratio to the current in the resistance of a potentiometer, so that when the potentiometer output is balanced with the voltage drop across the portion of the earth circuit under test the resistance of the potentiometer up to balance point is directly proportional to, and is calibrated in terms of, the test resistance, a voltage is injected into the potentiometer circuit to compensate for natural earth potentials, and a device indicates when the test resistance is in circuit. As shown, the predetermined ratio between the current supplied to a vernier potentiometer P, which may be shunted by a resistor 16, and that fed to earthed electrodes Cl, C2 is obtained by adjusting resistors R1, R2, R3, R4. Any natural earth potential between electrodes P1, P2, which determine the test resistance, is balanced by the output of a potential divider 22 before the test resistance is connected to the potentiometer P. If battery B is initially connected to electrodes P1, P2, an indication is obtained on an instrument 26 when these electrodes are positioned in the earth.
