Title: Improvements relating to electronic switching circuits
Inventor: CLAYDEN RONALD THOMAS
IPC: H04N5/268
Filed: 1949-10-19
Abstract: 693,895. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 27, 1950 [Oct. 19, 1949], No. 26786/49. Class 40 (vi). In an electronic switching circuit, particularly for inserting blanking pulses or other suppression pulses into a television waveform and comprising a diode valve which may be switched selectively to a conducting or to a non-conducting condition, means are provided for supplying a biasing current to the diode when in its conducting condition so that the application thereto of zero-amplitude signals, i.e. signals giving rise to an output equal to that obtained when the diode is non-conducting, does not cause the diode to operate at or near its cut-off point. In the arrangement shown, television picture signals from a source 4 are fed to a load comprising two equal resistances 3, 14 by transmission through diodes 5 and 6 which are periodically rendered non-conducting (e.g. at blanking intervals) under the control of switching pulses from source 13, which pulses render valve 9 conducting and thus the diodes 5, 6 non- conducting by causing the potential of the diode anodes to fall below that of earth (the line 12 being negative with respect to earth). To ensure that the diode 6 operates over a linear portion of its characteristic when the potential of the signals at the cathode of valve 2 falls to zero or lower, a further valve 11 is arranged to conduct when valve 9 is non-conducting (and vice versa), whereby its anode current, dividing between the equal resistances 3, 14, supplies a biasing current for diode 6 which causes it to operate on a linear portion of its characteristic. Specifications 682,159, [Group XL (b)], and 693,893 are referred to.

IPC: B21F99/00
Filed: 1956-09-05
Abstract: 826,682. Shearing; stamping; bending. HEENAN & FROUDE Ltd. Aug. 30, 1957 [Sept. 5, 1956], No. 27188/56. Class 83 (4). [Also in Group XXIX] In an automatic machine for making metal articles from wire or strip, in which the machine is self-feeding from a coil of the wire or strip which is processed at a plurality of operating stations by suitable tools which cut off and form the articles, a pressure fluid operated ram or plunger for operating the forming member or tool is provided at each of selected operating stations, actuation of the several rams or plungers of the selected stations being effected by cam-operable means remotely controlling, from a centralized control position, the operation of valves associated with the respective ram cylinders for controlling the supply of pressure fluid thereto. An automatic machine, which includes a strip straightener, a feed unit, a stationary gripper, a horizontal press which may pierce, trim, stamp or emboss the work, a cut-off unit, four bending slides and a vertical forming slide, has an hydraulically operated power unit, Fig. 2, at each work-station, the units being interchangeable. Each unit comprises a tool-operating ram 5, to the cylinder 4 of which fluid is introduced through a valve cylinder 11. A spring-biased piston valve 12 connected to the rams is actuated, through a linkage mechanism and a cable 26 in a flexible sheath 27, by a cam 29 acting on a lever 28, Fig. 5. Cams 29 for the various units are mounted on a common removable cam shaft 31 driven by an electric motor or by a pressure fluid motor. The stroke of the ram 5 is controlled by the amount of initial displacement of the piston valve 12 from its neutral position, movement of the ram 5 returning the piston valve, through links 22 and 30 thus terminating the stroke. The travel of the plunger is adjustable to vary the pressure on the work by varying the position of one end of the flexible sheath relative to the cable 26 by means of a spindle 53. A reciprocating gripper feeding strip or wire to the work-stations is also actuated by an hydraulic unit. In a modification the units may be pneumatically operated. In another modification two units may be associated with a single tool.

Title: Wringers
IPC: D06F45/18
Filed: 1939-10-04
Abstract: 537,011. Wringers; machinery guards. LOVELL MANUFACTURING CO. Oct. 4, 1939, No. 27191. Convention date, Oct. 7, 1938. [Class 138 (ii)] [Also in Group XXIV] A wringer is mounted on its supporting head so as to permit lateral swinging and vertical movement and is so connected with an arm extending outwardly from the head that a lateral swinging movement of the wringer from operative position, e.g. in case of emergency, effects an upward movement of the wringer to release a safety device. The wringer is mounted by a bolt 39, extending through a vertical slot 40, to a supporting head 17 adjustable on a pillar 18 housing the driving shaft 23 which drives through bevel gears 24, 25 and a pinion 28, a pair of pinions 29, 31 adapted to drive the lower roll 4 through pinion 33. The stiles 2, 3 are pivoted by pins 37 to rockers 35 engaging by wedge-shaped cams 41 with lugs 34a on the outwardly extending arm 34, and may be held so that the pinion 33 is in driving engagement with one of the pinions 29, 31, or in reversing engagement with the others, or may be moved to neutral disengaged position by the action of the cams 41, and this change over may be effected by a pull by the operator in the event of his fingers being caught in the rolls. Further, the pressure of the rolls may be released by a pull or push on guard rails 16a whereby a lug 16 secured thereon rocks a toggle 15, 15b, the cams 41 then moving the pinion 33 to neutral position. The invention is associated with a roll-pressure release device described in Specification 498,784.

Title: Improvements in or relating to transposing heads for use in the manufacture of transposed multiple strip conductor
Inventor: HINDS RONALD
IPC: H01B13/02
Filed: 1958-08-25
Abstract: 920,532. Transposed-conductor stranding machines. BRITISH INSULATED CALLENDER'S CABLES Ltd. Aug. 24, 1959 [Aug. 25, 1958], No. 27205/58. Class 36. A transposing head for making transposed multiple strip conductors of rectangular crosssection comprises four movable fingers 58 and 66 having ends adapted to engage the four corner wires of the conductor, each finger being mounted in a carrier 38 and each carrier being held on a slide bed 41 extending parallel to one of the four walls of a rectangular closing die and being slidable thereon towards and away from the die axis in a plane normal thereto. In order to accommodate different numbers and thicknesses of wires, each of the two vertical fingers 58 is adjustable longitudinally in its carrier by being mounted in a groove therein and held by a screw 59 located in a slot 60, and each horizontal finger 66 is adjustable laterally in its carrier by being pivoted at one end 67 and held by a screw 68 in a lateral slot. The carriers are located in channels 34 to 37 formed in a circular cover-plate, each channel being wider than the associated carrier so that an end of the latter may be lifted clear of the slide bed 41 against the restraining action of a spring 42 which also provides restoring action when a carrier is moved along its slide bed towards the axis of the closing die. Movement of each carrier along its slide bed, to cause the associated finger tip to engage with and transpose a wire or stack of wires, is effected by a rocker arm pivoted at 46, one end of the arm 48 carrying an adjustable screw 49 for engaging with a projection on the carrier and the other end 55 carrying a roller 57 which engages with the profile of a circular cam 23 (Fig. 2) carried on a vertically-mounted base-plate 1, which also carries the closing die 15 and which is bolted to the outer rim 4 of the cover-plate so that the assembly forms the transposing head. The cam is driven through a chain and sprocket drive 28, 22, 29 at a speed proportional to that of the bobbin cage feeding the wires to the head. If the conductor is to be formed of an odd number of wires then the cam has a single " lift " 24 of 90 degrees followed by a " dwell " 25 of approximately 90 degrees and a sudden drop 26. For an even number of strips the cam has two such profiles spaced 180 degrees apart. For an odd number of strips the carriers are preferably linked at their inner ends by a pin-and-link parallelogram 77, 78 so that when one carrier moves inwards to displace a wire or stack the carrier opposite is displaced by the attached link to provide clearance for the wire whilst maintaining support for the stack. In order that a range of conductor sizes may be accommodated the closing die is in the form of an interchangeable bush 13 located in the base-plate 1 and each die may be provided with heightadjusting internal shims to cater for different numbers of wires (Figs. 5 and 6, not shown).
