Patent GB-1016214-A (GB)
Title: Electrode mount and method of manufacture thereof
IPC: H01J23/26
Filed: 1963-03-14
Abstract: <PICT:1016214/C1/1> <PICT:1016214/C1/2> A method of bonding a metal wave-conducting member to a refractory insulating member in a travelling wave tube comprises supporting the members in juxtaposition and passing an electric current through the metal member for a fraction of a second so that the metal is momentarily heated above the fusing temperature of the insulator, causing a surface portion of the insulating member to fuse and bond to the metal.  The insulator may be of glass or ceramic.  In one embodiment (Fig. 1) a travelling-wave tube comprises a metal helix 30 mounted in cylindrical glass portion 16 of an envelope 10, with electron gun portion 12 and metal collector portion 14 at the ends.  The inner surface of envelope portion 16 is provided with longitudinal ribs 32, to which each turn of the helix is bonded by means of pedestals 34 of glass (Fig. 4).  To form this bond, a metal helix, e.g. tungsten wire, and a section 16 of internally ribbed glass are supported by a jig. The helix, of slightly smaller diameter than the inscribed circuit diameter of the ribs, rests on the two lower ribs and is spaced from the upper rib.  Preferably, the assembly is enclosed in a non-oxidizing admosphere.  After heating the glass slowly to between the strain and softening points by means of a current source connected across the helix, the current is suddenly increased for e.g. 0.1 secs. causing the helix to expand and fuse, by conduction of heat, those parts of the glass envelope in contact therewith and form a metal-glass bond.  The sudden contraction of the helix, as the current-pulse ceases, causes the fused glass to pull out into pedestals 34.  A low current is then maintained for a period sufficient to anneal the glass. Alternatively, the initial heating, and subsequent annealing of the glass may be effected by placing the assembly in an oven. Preferably, the coefficient of thermal expansion of the metal is greater than that of the glass.  In another embodiment (not shown) a helix is mounted in an insulating or metal envelope by means of ceramic or glass rods which are bonded by pedestals to the helix. When forming a metal-ceramic bond, preheating of the ceramic is unnecessary.

Connecting uppers to insoles and soles; soles; insoles.-In a process of manufacturing, under ordinary factory conditions, boots and shoes which will conform more accurately to the anatomical structure of the foot than the standard types at present worn, an insole 2, prepared in the usual way with a channel lip 4 and preferably provided with an additional area of stock 6 along its inside shank portion, is slit at its heel end by means of a " buttonhole " cut extending approximately centrally from the rear edge to the heel breast line, and is scored at 16 on its under or flesh side by a cut extending forwards of a perforation at the end of the cut, along the median line of the insole, through the shank substantially parallel to the in. side channel 4 to approximately the ball line. The parts 8, 10 formed by the cut are then opened out to cause the stock along the inside shank to buckle upwards and form an arch 18 corresponding substantially to the lateral and transverse conformation of the shank portion of the foot it is to support. The insole is locked in this position by a wedge 22 inserted between the members 8, 10 and secured by offsets 24 engaging notches 14 in the edge of the members, and by staples 26. The insole and an upper 30 are then assembled upon a last similar to an ordinary last except that its shank portion is somewhat deeper, the offset member 8 is trimmed to size, and the shoe is then lasted and welted in the ordinary manner. The usual filler 36 is then applied, and, if desired, a resilient shank 38 is secured in position. An outsole 42, which is buckled in a similar manner to the insole, is then secured to the welt by stitches 60, and finally a heel 62 is attached.

Abstract: 1498043 Automatic control RCA CORPORATION 13 March 1975 [14 March 1974 (2)] 11430/74 and 11433/74 Heading G3N In magnetic tape apparatus, tape is moved from a supply reel to a take up reel, each driven by a motor. The rotary speeds of each reel, and the linear speed of the tape, are measured and each reel drive motor controlled according to a periodically varying reference signal and the relationship between the linear tape speed and the rotary speed of the respective motor being controlled. The motors are energized from an A.C. source and the periodically varying reference signal is in timed relationship with this A.C. source. In the embodiment, the energization of a supply drive motor 21 from the A.C. source is controlled according to the reel and tape speeds as measured by tachometers 23, 17. The relationship between these speeds, which varies as the diameter of tape on the reel, is determined by a counting circuit, see Fig. 2 (not shown), sampled and held at 29 and converted into a D.C. voltage dependent upon the diameter. This D.C. voltage is compared with a sawtooth signal from circuit 37 to control the firing of triacs in the motor drive. The sawtooth signal has a dwell time between ramps that is varied according to the line voltage of the A.C. source, see Specification 1498044, Division H3-5. The drive of take up reel 19 is similarly controlled according to the tape linear speed and the reel speed, as measured by tachometer 23'. In the normal running mode, reel 19 is driven forward and a reverse, braking torque applied to supply reel 1 so as to maintain tape tension constant despite variations in the tape diameter on the reels, and despite fluctuations in the A.C. voltage source.
