Abstract: 806,893. Processing cathode materials. GENERAL ELECTRIC CO. Feb. 8, 1956, No. 3952/56. Class 39(1). A method of activating a thermionic cathode comprising a passive metal support with a layer of an alkaline earth metal compound thereon, comprises supporting the cathode within a chamber which contains a surface of a metal of the titanium group, evacuating the chamber and heating the surface to a temperature sufficient to reduce alkaline earth metal compound on the surface and to evaporate pure alkaline earth metal on to the layer of the compound on the cathode. An anode of titanium or other metal of Group IVa is coated with a thin layer of barium carbonate (about 0À1 mil) and a pure nickel cathode is coated with a thicker layer of barium carbonate or of a mixture of barium, strontium and calcium carbonates (about 0À5 to 2 mil thick). Both electrodes are then heated and held briefly at 800‹C. to convert the carbonates into the oxide. Both the anode and cathode are then heated to 1000‹C. and the titanium at the anode absorbs oxygen releasing barium metal which is vapourised on to the cathode. The carbonates may be prepared by suspension in amylacetate solution and the finer particles on settling are mixed in nitrocellulose binder. The anode 1, cathode 6, and grid 4 are assembled as shown, in Fig. 3 with ceramic spacers 2, 5, 8 between the grid, cathode and heater connectors 3, 7 and 9 respectively. Nickel shims between the anode 1 and spacer 5 melt on heating to 1000‹C. to form an eutectic mixture with the titanium which, on cooling, solidifies to form a seal. The evaporated barium also acts as a getter of any stray gases.

In a titration carried out to determine two components in succession, when a first end point is reached the addition of titrating agent is stopped and printer 36 prints out the amount of titrating agent used. Pulse generator 27 then controls further addition of titrating agent until the second point is reached. Detectors 17 may be in the form of a pH or redox measuring chain or a measuring chain of ion sensitive electrodes and are each coupled to an amplifier 18. There is reference to titration of sulphunic acid and copper in an acid copper bath with sodium hydroxide solution, and to detection of nickel and boric acid in a nickel plating bath by titration with a solution of Komplexon (R.T.M.)

A method of bundling articles of thin flexible sheet material, for example bags, includes the step of passing a suspension means presenting a loop and a stop means partially through a bundle of the articles until the stop means is on one side of the bundle and the loop is partly or wholly on the opposite side of the bundle. One form of the suspension means comprises a moulded synthetic component having a longitudinal shank 1 a cross bar 2 at one end of the shank constituting the said stop means and with the loop 3 at the other end of the shank, the sides of the loop being resilient so that although capable of contracting together when being passed through a hole in the bundle they separate again after having emerged from the bundle thus preventing accidental withdrawal of the loop from the hole and also providing means for hanging the bundle from a support. Various forms of stop means can be substituted for the bar described above e.g. buttons, balls or arrow heads. Another form of suspension means comprises a length of cord or string formed into a loop by having its two ends gripped in the opposite ends of a single metal tube or ferrule which constitutes the stop means. A further alternative form consists of a closed loop with a blob constituting the stop means at one point.

Abstract: 1527051 Machine tool control EXPERIMENTAL N-I INST METALLOREZHUSCHIKH STANKOV 4 Feb 1976 04323/76 Heading G3N A control system, e.g. for an electro-erosion cutting, milling, laser cutting or etching machine, uses an optical head 7 which follows a line 3 on a drawing 2 mounted on a co-ordinate follow table 1. The head is on carriage 4 driven in x, y directions by step motors, 5, 6. A rigidly supported table 8 carries workpiece 9 on which a cut corresponding to line 3, is produced by thin wire erosion tool 10 on slide rest 11 driven by step motors 12, 13. The head 7 output passes via D.C. amplifier decoder 14, with four outputs corresponding to respective thresholds, to a unit 24 for selecting the rotation direction of the drive motors which has a reversible ring shift register 25 and receives outputs from threshold amplifier (decoder) 23. The register receives the outputs of four switches 19, 20, 21, 22 which set an initial combination of rotation directions of step motors 5, 6, 12, 13. Unit 15 also has three pulse generators 16, 17, 18 which control working speed. Coincidence circuit 26, comprising AND gates 29-52 and OR gate 53-58, has outputs connected to amplifiers 27, 28 which change motor rotation direction as necessary. The head 7 Fig. 3 (not shown) has a light source which shines light via a light guide into the drawing line, reflected light being passed via a projection head and guide to a photo-receiver whose output varies with the reflectivity of the drawing, ie whether or not the line is being scanned, and thus triggers varying threshold outputs in amplifier 14. The circuitry thus ensures that the cutting of workpiece 9 only occurs when the line 3 is being followed exactly.
