Title: Improvements in or relating to electric discharge tubes
IPC: H01J19/42
Filed: 1946-08-22
Abstract: 624,009. Making electrodes for discharge tubes. PHILIPS LAMPS, Ltd. Aug. 22, 1946, No. 25083. Convention date, Nov. 14, 1942. [Class 83 (ii)] [Also in Group XL (a)] An electrode system comprising a cathode and one or more other electrodes is formed by starting with two or more concentric conductors 1, 2, 3, Fig. 1, separated by insulating material 4, hammering and/or drawing the structure, and then removing one or more of the conductors and if necessary one or more intermediate layers of insulating material over part of the circumference, e.g. by grinding. In one form, Fig. 1, the inner conductor 1 is finally coated with emissive material 5 over its exposed surface and the exposed edges of conductors 2 and 3 form grids. In another form, Fig. 2, none of the insulating layer 13 is removed and this layer is also electron emissive. In modifications of the arrangement of Fig. 1, the cathode may be indirectly heated in which case it is made up of either two concentric conductors separated by insulating material, the inner conductor acting as a heater, or alternatively the heater itself may be made up of two concentric conductors separated by insulating material so as to nullify the magnetic field associated with the heater current. To strengthen the structure the outer conductor or conductors in all cases need not be entirely removed over the section of the circumference, small " bridges " 15, Fig. 1 being left. An anode (not shown) surrounds the electrode structure or may be included in the structure as well as or instead of the grids. The conductors may be of nickel, tungsten, or molybdenum, and the insulating material may be of magnesia, alumina, beryllia, zirconium oxide, a mixture of silica, alumina, magnesia, or an alkaline earth oxide such as barium oxide which is also electron emissive.

Title: Plate clamp mechanism for use on printing machines
IPC: B41F27/10
Filed: 1947-09-17
Abstract: 656,179. Printing-surfaces. HOE & CO., Ltd., R. Sept. 17, 1947, No. 25412. Convention date, Sept. 18, 1946. [Class 100 (ii)] A printing cylinder to receive a curved stereotyped printing- plate having clamping surfaces formed by recesses at the underside of the plate comprises clamps to engage a plate at its curved end, other clamps to engage the recesses, and an operating member which actuates means to move all the clamps into clamping position. The cylinder has eight axial channels 2-9, Fig. 2, containing clamping mechanism for eight semi-cylindrical stereotype plates, there being an axially central stationary circumferential clamp and four plates being clamped at either end of the cylinder, two of them having one curved edge secured by the central clamp. At either end of the cylinder, two segments 10 are guided by bolts entering the cylinder and hollow shafts 40 passing through the channels, being capable of limited axial movement. Each segment is moved by an arcuate member 14 movable circumferentially by a wrench 17 and having a cam groove 20 engaging a roller 21 on the segment to move the latter axially, the members 14 and 10 being locked by a spring- pressed plunger when the wrench is not in position. In the channel 2, a curved edge clamp 30, Figs. 2 and 4, is secured by a pin 43 passing through a slot in the shaft 40 to an inner shaft 41, and when the segment 10 moves inwards the clamp engages the edge of a plate A under the pressure of a spring 42. On retraction of the segment, a collar 61 on the shaft 40 retracts the clamp with some lost motion. A series of clamps 31 for engaging recesses in the underside of the plate are spaced along the channel and each is mounted on a base 50 having a roller 51 engaging a cam groove 56 in the cap 52a of a cam block 52 secured to the shaft 40, whereby on movement inwards of the segment 10 the clamp 31 moves into clamping position. The last part of the groove 56 is of shallow pitch to prevent movement of the block 52 by reaction of the clamp 31. Each block 52 is urged by a spring 60 into clamping position and retracted with lost motion by a collar 62. An intermediate curved edge clamp 71 is slidable on the shaft 40 and engages a curved edge of plates A and B, being retractable with considerable lost motion by a pin 73 to release the plate B later than the plate A. All the channels have similar clamps 30 and 71, but at the near end of the cylinder, Fig. 2, only the channels 2, 5, 6 and 9 have clamps 31. The shafts in the channels 3, 4, 7 and 8 extend only as far as the clamps 71, those in the other channels extending to the central stationary clamp. At the far end of the cylinder, the plates are held with an angular displacement of 90 degrees, the clamps 31 being associated with the channels 3, 4, 7 and 8. Spaced along the cylinder in channels 82 are straight-edge stops 84 capable of limited chordal movement.

Title: Improvements in automatic cable stretching devices
IPC: B64C13/30
Filed: 1951-10-31
Abstract: 714,174. Wire strainers. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-EST. Oct. 31, 1951 [Nov. 2, 1950], No. 25464/51. Class 45. [Also in Group XXXIII] An automatic stretcher for double cables having an operating side and a return side initially stretched at the same tension, especially for aircraft control cables, such stretcher acting on both sides of a cable, is characterized by comprising for each side an independent movable direction changing device, means adapted to maintain substantially constant and equal to said same tension the initial tensions of both sides when subjected to varying causes other than control operation, means for substantially limiting to a preselected value the decreasing tension of the return side when the tension in the operating side reaches a value equal to double the initial tension less the minimum residual tension of said return side, means for locking the direction changing device of the operating side when said tension limiting means becomes operative, and means to render inoperative the tension limiting means when the corresponding direction changing device has been displaced to a determined extent through the action of said tension limiting means. In the embodiment described, two pulleys 9 and 9a guiding the cables through approximately 90 degrees are mounted between two sets of plates 10 and 10a, which are pivoted on a common axis 5 fast to bracket 6 on the aircraft structure. Also pivoted on axis 5 is a pusher 1 having a cut-out to receive the pulleys, and members 36 to push against the pulley axle heads 14 and 14a (not shown). Springs 24 act on pusher 1 to keep the cables taut and are adjustable by bolts 29. Springs 31 are provided to urge plates 10 and 10a away from pusher 1. When the cables are operated, one side (cable 34, say) tends to slacken, and the other to tighten, holding back pusher 1. When the tension in side 34 decreases to less than that produceable by spring 31, plates 10 are urged outwards, and axle head 14 depresses lever 16 to mesh with plate 33, locking pusher 1 and converting pulley 9a to a simple angle guide. Pulley 9 continues to take up the slack of cable 34, moving along lever 16 until plates 10 reach a stop, when the cable slackens. Variations in tension due to temperature changes and structural deformations are taken up by springs 24 which may take the form of spiral extension or compression springs, blade springs, torsion bars, or hydraulic or pneumatic devices. In a modification, a single lever 16 and plate 33 are provided between the pulleys, the axle heads of the pulleys each bearing on half the lever.
