Title: Improvements in or relating to electrical circuits employing static electrical switches
Inventor: ODELL ALEXANDER DOUGLAS
IPC: H02M3/338
Filed: 1954-03-19
Abstract: 786,056. Electric digital - data - storage apparatus. STANDARD TELEPHONES & CABLES, Ltd. March 11, 1955 [March 19, 1954], No. 8109/54. Addition to 663,574, [Group XXXIX]. Class 106 (1). A pattern moving shifting register representing data by the conductive state of transistors is characterized in that each stage contains only one transistor which can be either on-conducting heavily, or off-conducting slightly. Each point contact transistor, X<SP>2</SP> has its emitter connected to a supply line - P normally at - 3v. and over which negative stepping pulses are applied, its collector connected via a load R<SP>21</SP> to a - 20 v. supply line and its base to an earth line via diodes G<SP>13</SP> and G<SP>12</SP>, the latter of which is also connected to a stabilizing 50 v. supply line via a resistor R<SP>13</SP> and forming with the resistor the base load over which feed-back takes place. At the leading edge of a negative shift pulse any transistor in its on state, say X<SP>2</SP>, is cut-off causing the potential of the upper plate of a condenser C<SP>22</SP> to become more negative than - 3v. At the end of the shift pulse when the voltage on line - P returns to - 3v. those transistors, X<SP>3</SP> in particular, adjacent to a preceding trigger that was on. have their bases more negative than - 3v. which is the emitter potential. They are thus caused to go on and the pattern is stepped one stage. A diode G<SP>21</SP> prevents positive pulses being transmitted from transistor X<SP>2</SP> to transistor X<SP>3</SP> and a diode G<SP>13</SP> prevents transient current due to the discharge of C<SP>22</SP> flowing in the common emitter line. A modification shows how parallel to serial and vice versa conversion may be effected.

Title: Improvements in or relating to web-renewing mechanisms for printing presses or other web machines
IPC: B65H19/18
Filed: 1919-04-09
Abstract: 144,026. Goss Printing Press Co., (Goss Printing Press Co.). April 9, 1919. Feeding webs.-A web-roll changing mechanism for printing or other machines comprises means for supporting two web rolls in position for alternative feeding without shifting either roll, and a roll-rotating device which is movable into engagement with the surface of either roll, when fresh, to bring it to a surface speed substantially equal to that of the expiring web from the other roll. As shown, the frame is provided with two roll supports 19, 20. The web 23 from the lower roll is fed to the press by belts 24, 25 26, and, when the press is being fed from the upper roll, the web is fed by the belts 25, 26 only. The belt rollers 34, 37 are grooved for the passage of the bolts. When the web in. use is nearly exhausted, the fresh roll, prepared by lightly attaching the end of the web to the body of the roll and applying patches of adhesive to the end of the web, is rotated at the speed of the expiring web by belts 42 passing round rollers 44 fixed to a shaft 45 and round rollers 46 carried bv arms 48 secured to sleeves loose on the shaft 45. One of the sleeves is connected by an arm 50, link 51, and arm 52 to a hand-lever 54 by which the belts are thrown into contact with a fresh roll in either position. The shaft 45 is driven from the press through a shaft 61 and reversing-gear comprising a bevel-gear 58 fixed to the shaft 45 and meshing with two bevel-gears 59, 60 loose on the shaft 61 and adapted to be connected thereto alternatively by a clutch 62. A web-stripper 68 coacting with the upper roll is secured to a shaft 69 and is normally held out cf contact with the roll by a latch 71 engaging a notched collar on the shaft 69; but, on release of the latch 71, the stripper is raised by a spring into contact with the roll, and the end of the web is thereby stripped from the roll and is guided by the stripper and a stationary guide 71 into the bite of the belts 25, 26, which effect the junction of the webs. The old web is then severed. To prevent continuous contact of the stripper 68 with the web roll 17 during the feed from that roll, the shaft 69 is connected by linkage 78, 79, 80 to a lever 82 carrying a roller 83 engaging the roll. A stripper 64 mounted and controlled similarly to the stripper 68 is provided and serves for stripping the web from a fresh roll in the lower position and guiding it to the bite of the belts 24, 25. In a modification, the belts 24 are dispensed with, the web from the lower roll passing directly to the bite of the belts 25, 26. In this construction also, the belt pulleys 44 are on a shaft separate from, but geared to, the shaft 45, the swinging of the belts being effected by a hand-lever secured directly to one of the sleeves carrying the arms 48.

[Class 17 (i)] [See also Group XXIII] In a machine for performing a cutting operation on a heel, particularly for cutting a transverse groove in the breast surface, manually operable means are provided to cause relative movement between the cutter and a heel carrier during the cutting operation and automatic means are provided to control the rate of movement between the carrier and the cutter. In the machine shown, which is similar to that described in Specification 421,882, a heel H is supported by a carrier 67 which is fixed to a slide 49 movable in a guideway in a fixed plate 43. The carrier and slide are moved towards a rotary cutter 7 by a hand lever 61 connected to the slide by a pin 68 and slot 70 until an arm 55 on the slide moves a driven pulley 119 loose on a shaft 117 into engagement with a clutch surface 125 of a sleeve 123 on the shaft ; consequent rotation of the shaft moves the carrier 67 and slide 49 at a rate determined by a screw on the shaft, until the arm 55 reaches the end of a slot 57 on the fixed plate 43. Release of the hand lever causes a loose pulley 121 driven oppositely to and faster than the pulley 119 to engage a clutch surface 129 under the influence of a spring 75, Fig. 2, and to return the heel carrier. The heel is held on the carrier 67 by laterally adjustable gauges 81 and a co-operating clamping member 97 moved into and out of position by a hand lever 111 and controlled by a spring 113 moving over a dead centre. To provide access to the cutter 7, the plate 43 is carried by an arm 27 pivoted on a pin 31 and normally held in operative position by a pivoted yoke member 39 provided with a screw 41 engaging the arm 27.
