Title: Emissive fused electrode

Abstract: 1394068 Cathode materials ITT INDUSTRIES Inc 11 May 1972 [17 May 1971 4 June 1971 7 June 1971 3 Dec 1971 (2)] 22133/72 Heading H1D A cold cathode comprises a fused mixture of a metal and an electron emissive material having a bulk density gradient. The mixture may be in a metal cup or form an ellipsoidal or conical pellet with a nail headed conductor extending from it; there is a void in the pellet above the electrode end. The mixture comprises 50-80% by weight of Ta powder and BaO 2  powder; C, Sr and Zr compounds may be added to retard emission. Other mixtures include W, Mo, Th, Ti, Zr, Ni and Fe powders with BaO, Ba nitrate, CaO, SrO, ZrO and Li, Ce, Na, K compounds. The cup is of Fe, Ni plated Fe, Ta, W or Mo. The powder is compressed at 1000- 4000 PSI in a cup which is then covered with an apertured lid and heated to 700-1000‹ C. This starts an exothermic reaction which continues until it self extinguishes. The resulting mixture has a concave, jagged top surface within the cup comprising 25-50 Á particles and 80% voids and a denser interior of particles less than 1 Á with only 10% voids. Pellet electrodes are formed by compressing the powder in a mould with a Ni, W, Ta, Fe or Ni lead extending into the mixture and heating. When the heating vessel is larger than the pellet and sealed, an ellipsoidal pellet is formed. When the pellet is heated in the mould covered by a vented lid with a concave inner face a cylindrical pellet with a conical end is produced in which only the end has a density gradient, the sides are smooth thereby reducing sputtering. The electrodes are used in fluorescent lamps.

Limbs, artificial.-Comprises a construction of an artificial arm of the type in which the opening and closing of the fingers is controlled by movements of the elbow joint, adapted particularly for cases in which the arm has been amputated below the elbow but which may be modified for cases of amputation above the elbow. The hand consists of four articulated fingers and a thumb, the whole structure being rotatably mounted on a hinge-pin 6. stops being provided to limit the motion in both directions. Finger flexing-cords 12 and extending-cords 13, Fig. 3, passing round guide-pulleys 11 within the fingers, are connected to straps 16, 17 respectively which are adjustably attached to a band 23 which passes around the upper-arm bucket 1, so that when the elbow is bent about the pivot 4 the fingers are flexed. The operating-cords 33, 34 of the thumb pass around pulleys and are connected to straps 43, 44 which are fastened to a band 21 encircling the forearmstump bucket 3 in such a way that an outward turning of the elbow extends the thumb whilst an inward turning flexes it. In a modified construction one set of controlling-straps may be dispensed with, the fingers being returned automatically to their normal open or closed position by springs, and the fingers may be made of flexible rubber instead of being jointed.
