IPC: H01J7/18
Filed: 1954-07-23
Abstract: 767,330. Discharge apparatus. M-O VALVE CO., Ltd., WHELDON, R. J., WIDDOWSON, A. E., and WILKINSON, K. H. July 5, 1955 [July 23, 1954], No. 21647/54. Class 39(1). A dispersed getter container is closed at normal temperatures but opens when heated by virtue of the different thermal expansions of different parts. As shown, a cup 1 of nickel has nested within it a cup 2 of molybdenum which has a lower coefficient of expansion. The cups are held together by a nickel eyelet 3 and spacer washer 4 and contains pellets 5, 6 of nickel-clad barium. When heated to vaporize the getter an annular gap opens between the cups, but this closes again on cooling and retains getter ash within the container where it will not upset the valve during working. The opening 1 may alternatively be due to differential heating of materials of the same coefficient of expansion.

Abstract: 872,045. Sheet-metal joints. NEWMAN & GUARDIA Ltd., and FITCH, S. G. Oct. 18, 1957 [July 18, 1956], No. 22314/56. Class 83 (4). A machine tor securing one or more soldering tags to an appropriately perforated panel of insulating material, is characterized in that, each tag is presented to the panel in the appropriate position so that it enters the appropriate perforation and passes through the panel and a twist is then given to the parts of the tag projecting from one side of the panel so as to secure the tag in position. The machine comprises an intermittently-rotatable disc 1 having a series of recesses 2 around its periphery for receiving panels 3 from a pile 4 housed in a tube 5. Holes 7 in the disc 1 below each recess correspond with the apertures in the panel. The machine head consists of three superimposed vertically - reciprocable plates 8, 9 and 10 mounted on one or more guide-bars 11. The tag feeding means comprises a splined mandrel 13 passing through the top plate 8 and secured to the middle plate 9. Reels 14 supply tag-strip to the splines of the mandrel down which they are fed by spring-loaded pawls 16 arranged around the mandrel in the lower face of the plates 8 and 9. In operation, when the upper plate 8 is lowered, the pawls 16 engaging in the notched tag-strips, feed the tagstrips down the mandrel splines and when the upper plate engages the middle plate 9, both move downwardly until the ends of the tagstrips projecting beneath the middle plate 9 pass through the openings in the panel 3 held in the disc 1. When the upper plate is returned to its initial position the pawls 16 in the middle plate prevent the tag-strips from moving back along the splines while the pawls in the upper plate slip over the tag-strips. The lower plate 10 is provided with slotted pins 17 for twisting the tag ends. Each pin has an arm 183 for engaging in one of the slots 182 provided in an annular plate 180 (Fig. 5) which is partly rotated by a pneumatic ram 190. After the lower plate has been raised and the tag ends twisted the tags are separated from the strip by knives such as shown at 20 mounted on the middle plate 9 and operated by an annular cam-plate 18 partly rotatable by a pneumatic ram 19. Finally, the lower plate 10 is lowered, the disc rotated to bring the next panel into alignment with the mandrel and the upper plate raised to its initial position. A boss 8<SP>111</SP> on the upper plate engages the underside of a flange 9<SP>111</SP> on the middle plate so that the middle plate and the mandrel is also raised with the upper plate in readiness for the next operation. The plates are operated by compressed air rams. The tags may be inserted in straight lines, triangles, concentric circles, squares or other shapes and the mandrel is shaped accordingly.
