Title: Improvements in and relating to methods of and apparatus for manufacturing electric condensers
IPC: H01G13/00
Filed: 1949-07-29
Abstract: 662,306. Condensers. BRITISH THOMSON-HOUSTON CO., LTD. July 29, 1949 [July 31, 1948], No. 19986/49 Class 37 [Also in Groups VIII and XV] A method of transversely affixing conducting strips 82 to a strip 12 of moving mounting material, e.g. paper, at equal, spaced intervals, in which one of the strips is coated with adhesive, e.g. of thermosetting type, comprises the repetition of the following steps: (a) stopping the paper strip 12; (b) simultaneously severing transversely the conducting strip 14 and pressing the severed part 82 against the paper 12; (c) moving the paper 12 a predetermined distance. The method provides a reel 66 of paper with attached conducting strips 82 which is used for making condensers. A driving-shaft 29 continuously rotates friction rolls 59 and 67 by means of gears and chains, and intermittently rotates a roller 75 by means of a pin 27 engaging each quarter revolution with a notched disc 26 on a shaft 25 which also drives rolls 18, 19 for the strip 14. Hence whilst the roll 75 is stopped a reserve of slack paper strip 12 is being built up behind the roll 59, the reserve being passed over the roll 75 when it rotates to be taken up by the roll 67 during the next stationary period of the roll 75. The shaft 29 also drives indirectly a cam 44 which moves a beam 42 counter-clockwise about a pivot 43, the beam 42 having an adjustable screw 41 which bears on the top of a housing 32 formed with a knife-edge 33. Hence lowering of the housing 32 severs the strip 14 and simultaneously a heater block 54 secured to the housing 32 is pressed on to the severed part of the strip 14, the under-side of which is coated with adhesive. The machine is synchronized, whereby the cutting, pressing and heating of the strip 14 take place during the period when the rolls 75 and 18 and 19 are stationary, i.e. strips 14 and 12 are at rest in the vicinity of the parts 33 and 54. Specification 657,951, [Group VIII], is referred to.

The bumper 26 is cylindrical, rotatably mounted on a rod 28 and connected via brackets 30, (32), and an upright link 34 to the tow pin 34. The bumper 26 is also connected by a bell crank 36, cable 50 and latch 52 to a rear bumper 60, rotatable about a pin 62. The rear bumper is biased to a vertical position by a spring 70, Fig. 4, and is prevented from rotating in a clockwise direction by the engagement of a latch member 68, provided on bumper 60, with a blocking surface 58 on latch 52. When the tow truck 10 is part of a conveyor system its front bumper 26 contacts the vertically disposed rear bumper of a truck in front 90 and pushes it. If however, the blocking surface 58 for the rear bumper has been removed, contact of the front bumper 26 with the rear bumper will cause the latter to rotate about pin 62, the bumper 26 will ride up onto the rear bumper and rotate about rod 28, as shown on the right hand side of Fig. 3. This movement of the bumper 26 raises the tow pin disconnecting it from the drive means and also removes the blocking surface 58 of the rear bumper 60, resulting in the following truck 80 also accumulating.

Title: Improvements in and relating to the separation of sheet articles, such as black plates and the like
IPC: B21B47/04
Filed: 1932-07-19
Abstract: 404,049. Separating sheets after pack rolling. GENGE, J. A., Sunnycroft, Llanfair Gardens, West Cross, and GEORGE, D., 3, Eden Avenue, Glanmor, both in Swansea. July 19, 1932, No. 20464. [Class 83 (iv).] A pack X of sheets to be separated is inserted through a recess in a machine frame and mounted cornerwise in a trough 10 and prevented from falling forward by rollers 68, 168 and backwards by stops 80, 81. Tho bottom of the trough is cut away to allow the corner of the pack to project below, in the path of a reciprocated knife 26 which gets between the corner of the top sheet and bends out the corner from the pack. A hammer 35, mounted on lever arms 49 swing- ing downwards about the shaft 50 by the connecting rod 52 of a crank disc 53, slides down the groove 44 and strikes the bent corner to bend it into the recess 34 of the knife 26 so that the sheet corner can be gripped by finger grippers 39 which move down on the slide block 46 along with the hammer. A stop 42 pivots the cam lever 41 which urges the gripper jaws 39 to close on the comer of the sheet and hold it. The arms 49 are then swung up, so that the grippers 39 tear the sheet up away from the rest of the pack. On arriving at another stop 77 the lever 41 fouls it which separates the gripper fingers 39 and drops the sheet. As the sheet is stripped off the pack the pack support rollers 68, 168 move up by rack and pinion 72, 73 to allow stripping. The pack is moved up to the path of the knife by the pressure plate 13 connected by spring pressure to the cam actuated slide 14. The faces of the sheets which are burred by the previous shearing come in contact with the surface of the abutment 12 which exercises a planishing effect on the edges. The abutment 12 is moved up by a crank 22, but is timed to recede as the knife advances. As soon as the corner is bent out the scissors gripper 54, 56 is raised up by cams to grip the corner of the remaining pack and hold it during stripping of one sheet as before described. The pack is forced by spring pressure against the abutment 12, and the knife is adjustably set by wedge inwardly of the abutment face to a distance of one sheet thickness to engage the top sheet, or may be set to engage two sheets. When the sheet is being stripped off it is pulled from between the roller 68 and 168 which travel vertically up the framework over the face of the pack during stripping. The abutment 12 may be replaced by a second reciprocating knife.
