Title: High-compression beam generating system for velocity-modulated tubes
IPC: H01J3/02
Filed: 1956-12-07
Abstract: 828,224. Velocity-modulated tubes. STANDARD TELEPHONES & CABLES Ltd. Dec. 7, 1956 [Dec. 8, 1955], No. 37482/56. Class 39(1). In a high compression beam generating system particularly for use in velocity-modulated tubes e.g. travelling-wave tubes) with electrostatic and magnetic focusing means, the electron gun, which comprises a cathode 1, a focusing electrode 2 and an accelerating anode 3, is partially shielded by a cylindrical magnetic sheath 5 and a diaphragm 6 which forms a pole shoe. The magnetic gap 7, which may be an air gap or a ring of non-magnetic material permits a portion of the magnetic field to thread through the cathode region. This arrangement is said to reduce the noise factor of the tube since it is practically independent of the intensity of the magnetic field generated by the coil 10. The axial magnetic field component gradually increases from a low finite value in the cathode plane to its full value in the region of the plane 4. The sheath 5 and the diaphragm 6 are at different magnetic potentials and by varying these and the position of the magnetic gap 7 it may be so arranged that the magnetic equi-potential surfaces are normal to the desired direction of flight of the electrons. After its exit through the aperture in the pole piece 6 the electron beam traverses the working region in which it is utilised to interact, for example, with the electromagnetic field of a helix 8 and is finally collected at electrode 9.

In a tractor-mounted mower wherein the knife-bar is driven from the tractor by means including a belt-drive 59, one of the pulleys 42 of the belt-drive is mounted in an eccentric bearing about the axis of which is can be adjusted by a hand-lever 30 to tighten or loosen the belt. The mower is mounted on the tractor by means of a frame 1, 4 having connections 76, 78 to receive tractor hitch-links. The mower drag-bar 14 is pivotally mounted on a housing 9 which is itself swingably mounted on the frame 1, 4 about a vertical pivot 10 so as to be able to breakback in the event of the mower's encountering an obstruction. The belt 59 is partly covered by a hood 34 the forward edge of which acts as a detent to retain the lever 30, which is spring-loaded in any adjusted position. An arm 65 freely mounted on the pivot 10 carries a belt 67 the clapper 68 of which is normally just clear of the crank-disc 51 which drives the connecting rod 57 of the mower. When the mower breaks back, however, the crank-disc 51 contacts the clapper and gives an audible signal to the tractordriver. To avoid too violent a contact between the crank-disc and clapper, the arm 65 carries a plunger (Fig. 9, not shown) causing the arm and bell to move with the drag-bar as soon as the latter has moved far enough to actuate the audible signal.

Abstract: 1,198,988. Thermocouples. G. V. PLANER Ltd. 22 Aug., 1967 [31 Aug., 1966], No. 38946/66. Heading H1K. A thermoelectric module, as used in power generators and refrigerators, consisting of pairs of thermo-electric bodies (e.g. P and N type semi-conductors) linked by conductive connectors, is made by the following method. The bodies 11a, 12a are set up in parallel spacedapart relationship and an insulating encapsulant 13 is cast around and between them to form external walls 16 and internal walls 15. This is done in such a way that the walls extend beyond the ends of the bodies, except at locations such as 14 where adjacent bodies are to be interconnected. This leaves a plurality of cavities into which metallic material is then deposited to interconnect the bodies. The cavities may be formed by any of the following techniques: (a) casting the encapsulant to the level of the ends of the bodies, removing the body ends, e.g. by shot blasting or etching without removing the insulant and then removing the portions 14; (b) casting as in (a) but then, e.g. by use of a multi-head ultrasonic drilling tool, removing all the body ends and the portions 14 in one operation; (c) fitting "false" connectors to the body ends before encapsulating, encapsulating to the level of the false connectors and removing the latter after encapsulation. The metallic material inserted in the cavities may be Au, Cu or Ni deposited by electroplating or flame or plasma spraying.
