Patent GB-105768-A (GB)
IPC: B21D51/52
Abstract: 105,768. Wireless Hinge Manufacturing Co. April 20, 1916, [Convention date]. Hinges and pivots.-In a machine for making pinless-hinge boxes described in Specifications 25909/12 and 100,589, the lids 47, Fig. 11, and bodies 48 are placed in shoots 49, 50, having openings 258, 261, 265 to allow incorrectly-placed blanks to fall out, and a block 256 and bridge-piece 257 to prevent lids with the tongue first from passing. Fingers 250, Fig. 4, actuated by the three-arm lever 241 and the projection 138 on the lever 82, prevent any blanks being fed if the spindle 242 is pushed in, but allow the feed if it is pushed out. The blanks are fed by a stepped slide 53, Fig. 16, reciprocated by a cam on the shaft 87, Fig. 4, and the lever 82, retrograde movement being prevented by pawls 70, Fig. 16. When opposite the first and second dies 32, 33 the blanks are pressed thereon by spring pads 97, Fig. 7, actuated by a cam 116 and the linkwork shown, and are thus moved out of the way of projections 163 on the returning feed slides which move the blank to the dies 33, 34 at succeeding strokes. The upper die 32, adjustably carried by the crankoperated sliding head 28, stamps up bulbs 140 and a depression 141, Fig. 32, in the box 48, and forms a roll 147, Fig. 33, of the hinge tongue of the lid 47. The blanks are raised by spring ejectors 148, Fig. 7, and pushed off the dies by pads on curved arms 162. The blanks are clamped to the second die 33 in a similar manner, the upper die 33 cutting and bending up tongues 173, Fig. 36, and cutting out portions 177, Fig. 33, which fall down shoots 179, Fig. 7. The lid when opposite the third die 34 is held between members 182, 196, Fig. 22, and moved to engage the ends of the roll 147 under the tongues 173 by the cam 188 and lever 185 pivoted at 186. The upper die 34 then presses down the tongues 173, the holder 182 returns and the lid is raised to clear the die 34 by pins 192. The completed box is closed as it passes along the shoot 213, Fig. 24, and turned horizontal by engaging a projection 215. Any box body without a lid falls or is pushed by a spring out through a U slot 218, and unconnected lids are pushed from a slot 168. The lever 185 is lubricated through its hollow bearing 186, Fig. 4, and the frame 31 holding the lower dies, and is advanced for inspection by a screw 234 or a rack and pinion after the necessary bolts have been removed. A modified shoot for the lids has an inclined plate 273, Fig. 45, which deflects correctly positioned lids only to the shoot 275; all others fall out through openings or down the branch 272. In a modified holder 182 for assembling the parts, a permanent or electro-magnet holds the lid thereon.

Abstract: 677,983. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 25, 1948 [April 22, 1947], No. 10680/47. Class 39 (i). [Also in Groups XL (b) and XL (c)] Cathode-ray tube apparatus, of the type adapted to display electrical signals on the screen of a cathode-ray tube wherein the screen has a decay time which is so short in relation to the desired display time as to cause objectionable variations in brightness, comprises means for storing the electrical signals in a storage device and means for scanning the storage device a plurality of times to obtain derived signals which are in effect a plurality of repetitions of the signals, and means for reproducing the derived signals on the screen of the cathoderay tube. In Fig. 1 radar signals for a P.P.I. display are fed from an aerial 7 to an electron gun 4 and used to produce a positive charge image on the mosaic screen 2; this is discharged by slow electrons from the gun 5 and the output fed through an amplifier 15 to the display cathode-ray tube 16, part of the output from the amplifier being fed back to the gun 4 to renew the charge-image, the aerial 7 being disconnected. In another embodiment, Fig. 2, the display on the screen of cathode-ray tube 25 is focused on to the photo-cathode 21 of tube 18; the photo-electrons charge the mosaic 20 positively by secondary emissions. Electrons from the gun 19 scan the charge image and produce signals in the grid 22, but are unable to reduce the charge since the grid 22 is maintained at a potential above the first secondary emission cross-over point; thus the mosaic may be repeatedly scanned to produce output signals which are fed to the display cathode-ray tube 29. The tube 25 may be formed as an integral part of the tube 18. Two, three, or more storage tubes of the type shown in either Fig. 1 or Fig. 2 may be used with a single display cathode-ray tube.
