Title: Indexing drive mechanism
Inventor: DEACON DAVID
IPC: B23Q16/02
Filed: 1961-07-05
Abstract: 1,025,021. Toothed gearing. ENGLISH ELECTRIC CO. Ltd. July 3, 1962 [July 5, 1861], No. 24339/61. Headings F2L and F2Q. In mechanism allowing a worm-driven wheel 11, Fig. 1, to be locked in any one of a number of index positions, particularly for a nuclear reactor fuelling mechanism, the worm 10, engaging rollers 12 on the wheel 11, is longitudinally divided into two parts 13, 14 which co-operate to present to a roller 12 either a normal helical groove 17 extending over one and a quarter turns or, when part 14 has been shifted axially to align grooves 16 and 17, to present a part helical groove which as a 60- degree portion 18 of zero pitch providing a dwell in the drive. In a practical embodiment the parts 13, 14 (Fig. 4) are coupled for rotation by a pin 31, and the axial shifting of the part 14 is obtained by radially projecting an appropriate roller 28 or 27 into the path of respective cams 26, 25 (Fig. 2, not shown), cut into the surface of the part 14. In operation, using the normal helical groove 17, the wheel 11 is continuously rotated until the desired index station is approached. While the roller 12 still engages the part 13 the roller 27 is projected into the path of cam 25 so that the part 14 is moved axially to allow the roller 12 to enter the zero-pitch portion 18 and thus stop the wheel 11 accurately in the required index position. The worm 10 is then stopped. A block 36 on the end of a fixed spindle 34 projecting into the worm 10 has on one side portions 36A, 36B which co-operate with an inward projection 14B on the part 14 to prevent any axial movement thereof except when it is clear of the rollers 12.

Title: Improvements in or relating to web renewing mechanism for printing presses and other machines
IPC: B65H19/16
Filed: 1934-08-24
Abstract: 430,554. Feeding webs. JACKSON, L. MELLERSH-, 28, Southampton Buildings, Chancery Lane, London.-(Goss Printing Press Co. ; 1535, South Paulina Street, Chicago, U.S.A.) Aug. 24, 1934, No. 24456. [Class 100 (i)] In a web-renewing apparatus for printing-presses and other machines, having means for driving the reserve roll prior to the joining operation, means governed by the relative speeds of the periphery of the reserve roll and of the running web are provided for controlling the roll driving means so that the speed of the roll is equal to that of the running web. In one form, Fig. 1, the active roll A and reserve rolls B, C are mounted in a frame 1 rotatable to bring the reserve rolls successively into pasting and running positions. A motor 4 for each roll is connected to contact segments 7 rotatable with the frame 1, the segments of the roll in pasting position being connected through brushes 9 to the mains 10 through a manually controlled switch 11 and through a rheostat 52, 53. The rheostat arm 53 is actuated by a differential gear, Fig. 2, one side of which is driven from a roller 13 actuated by the running web 12 and the other side from a roller 14 driven by the roll B. The rollers 13, 14 drive in opposite directions, through bevel gearing, gears 30, 27 secured to sleeves 29, 26 loose upon the shaft 24 and carrying bevel gears 33, 32 engaging planet gears 34 carried by a block 37 fixed to the shaft 34. The shaft 24 carries a pointer 50 and a frictionally held collar 54 to which the rheostat arm 53 is secured. Stops 57 limit the movements of the arm 53, but the shaft 24 is capable of further movements. When the motor 4 is started, the higher speed of the roller 13 causes the shaft 24 to move in a clockwise direction until all the resistance of the rheostat is cut out. The motor speed thereby increases until the speed of the roller 14 exceeds that of the roller 13 when the shaft turns in the opposite direction placing resistance in the motor circuit until the speeds of the rollers 13, 14 are equalized. This condition is indicated by the pointer 50 remaining stationary. In a modification the bevel wheels 27, 30 of the differential gear are replaced by ratchet wheels actuated intermittently by pawls operated by solenoids. Current to the solenoids is controlled by rotary switches 90, 91, Fig. 8, carried by the rollers 13, 14 and having contact segments 92 which bridge contacts 94 in the solenoid circuits. In a further modification, Fig. 4, the reserve roll is driven by a roller 75 operated by gearing from a motor 72 which may be controlled automatically from the differential gear or by a manually operated rheostat 70 according to the position of a switch 71. The roller 75 is mounted on a stationary sleeve eccentric to the shaft 3 carrying the roll frame 1 so that it contacts only with the roll in pasting position.

Abstract: 1300870 Protective arrangements SYBRON CORP 20 May 1970 [2 June 1969] 24472/70 Headings H2H and H2K A device for protecting equipment situated in a hazardous area comprises a box 5 housing current and voltage limiting circuitry and provided with terminals 1, 3, the circuitry being embedded in encapsulating material 6. The load in the hazardous area is connected between terminals 3, 4 and the circuitry comprises a fuse F, resistors R1, R2, R3 and Zener diodes Z1, Z2, the diode Z2 becoming conductive at a voltage slightly less than that for the diode Z1. If the voltage applied between the terminals 1, 2 increases beyond its normal value the diode Z2 conducts and the increased current through the resistors R1, R2 should cause the fuse to blow. If, however, the fuse does not blow the increasing voltage causes the diode Z1 to conduct thereby further increasing the current through the fuse. A liquid epoxy resin is poured into the box and hardens to encapsulate the circuitry. A copper bus-bar G.B. connects the terminals 2, 4 and a plastics cover which engages projections 31, 35 fits over one end of the box.

In the damping device of the fluid-actuated power unit of the parent Specification the end of the cylinder which carries the extension n<SP>11</SP> (which enters the recess n<SP>10</SP> in the piston n<SP>7</SP>) is so formed that the position of the said extension relative to the cylinder can be varied axially. The part n<SP>2</SP> which carries the extension n<SP>11</SP> is screwed into the end part n<SP>3</SP> of the cylinder N and is locked in position by bolts n<SP>15</SP> passing through a knurled cap n<SP>16</SP> rotatably mounted on n<SP>3</SP>. The bolts screw into the end n<SP>2</SP> thus locking it and the part n<SP>11</SP> in relation to the cylinder N. To adjust n<SP>11</SP> axially, bolts n<SP>15</SP> are slackened, allowing cap n<SP>16</SP> to be rotated, and the bolts will then act as pins which can rotate the end part n<SP>2</SP> with extension n<SP>11</SP> to move the latter axially within the cylinder. The bolts are then tightened to lock the extension in place. The piston-rod n<SP>6</SP> may also be adjustably fixed to the crosshead a<SP>7</SP> as by being screw-threaded to enter a tapped hole in the crosshead, a lock-nut n<SP>17</SP> also being provided. This allows of adjustment of the commencement of the damping of the motion of piston n<SP>7</SP>.
