Abstract: 952,359. Discharge tubes. RADIO CORPORATION OF AMERICA. Sept. 9, 1960 [Sept. 11, 1959], No. 31198/60. Heading H1D. [Also in Division B3] In making an electron tube using a jig comprising a cup-like housing 52, Fig. 3, of oxidized nickel-chromium alloy, a pair of integral or non- integral hollow cylindrical elements 58, 60 extending from the base and a hollow cylindrical molybdenum insert 62 loosely fitted in the housing with a pin in the housing extending into a slot in the insert, a cylindrical nickel anode 26 is fitted over the cylinder 60, a molybdenum grid 28 is fitted between the cylinders 58, 60 and a nickel-chromium alloy cathode support sleeve 36 is fitted within the cylinder 58 and copper-coated steel anode, grid and cathode flanges 32, 34, 38 are disposed on their electrodes. The two legs 72 of a coil heater 44 are attached to a pair of copper-plated molybdenum conductors 16 inserted in molybdenum metallized bores, arranged in a circle, in a ceramic disc header 12 coated with molybdenum on its outer surface 49, the header is arranged on the top of the insert 62 and nine similar conductors 16, three for each flange, are passed through metallized bores, also arranged in circles, in the header into contact with the flanges. The assembly is heated in a reducing atmosphere furnace to melt the brazing material on the conductors and flanges to braze the parts together. The flanges and electrodes may be assembled into units prior to assembly in the jig. The brazed assembly is subsequently provided with a cathode emissive sleeve 40, Fig. 1, and a shell 46 is fitted to the header with a ring of hard solder therebetween. The complete tube results when the assembly is heated at a lower temperature than before in a vacuum to evacuate the tube, sinter the sleeve 40 to sleeve 36 and solder the shell to the header. Both conductors 16 connected to the heater 44 extend through the header but only one from each flange does so. The cylindrical wall 52 of the cup and the cylindrical insert 62 may be replaced by a number of circumferentially spaced elements.

Title: New or improved means for manipulating and conveying bottles and the like
IPC: B67C7/00
Filed: 1926-12-10
Abstract: 285,198. Chaloner, G. W., and Blaxter, A. P. L. Dec. 10, 1926. Bottling, corking and stoppering. - Grips for holding bottle necks while they are carried on conveyers through filling, sealing, emptying, or washing machines are interlocked so that they move in unison on the operation of one of them to release the bottle. Fig. 2 shows the invention applied to bottle-holders mounted on a circular table by means of inclined arms 6. Insertion of a bottle into the holder from underneath spreads the pivoted grips 9 by expanding the spring ring 11. The members 9 are intergeared as shown at 13, 14 so that actuation of one of them through the medium of the roller arm 15 opens both grips to release the bottle. Figs. 3 and 5 show the invention applied to a series of grips in line across the width of a conveyer belt. The grips are all mounted on two oppositely-disposed shafts 17 intergeared at each end as shown in Fig. 5 and all opened simultaneously against the action of the spring 19 by the roller arm 15. In a further modification each set of grips in the row is intergeared as shown in Fig 2, and a common shaft actuates all the members 15 simultaneously to open the grips. In this case the clips act individually when bottles are inserted and simultaneously when they are released. Specification 183,285 is referred to.

The addition of chlorinated phenyl to the composition described in Specification 744,388, consisting of an epoxide resin and endomethylenetetrahydrophthalic acid reduces the viscosity of the mixture and improves the pot life.  In examples: (1) 100 parts hexachloroendomethylenetetrahydrophthalic anhydride are dissolved in 20.5 parts pentachlorodiphenyl heated to 140 DEG  C. and the resulting solution added to 82 parts epoxide resin heated to 140 DEG C. and the product was cured by heating for 18 hours at 150 DEG  C.; (4) the pentachlordiphenyl was replaced by decachloroterphenyl. Phthalic, adipic and other dicarboxylic acids may be used in addition and fillers, e.g. magnetic powders, silica, mica, glass, clay, carbon and graphite may be added.
