Title: Improvements in and relating to electron discharge apparatus
IPC: H01J21/18
Filed: 1920-07-09
Abstract: 148,134. British Thomson - Houston Co., (Assignees of Hull, A. W.). Dec. 29, 1913, [Convention date]. Vacuum tubes.-A tube has an electron-emitting cathode, for instance an incandescent filament, an anode, an additional electrode for establishing a positive electric field so as to neutralize the space charge, and a winding for producing a magnetic field to confine the electron discharge into a beam by preventing the passage of electrons to the neutralizing-electrode. In one arrangement which mav be used as a detector in wireless receiving systems, a filament cathode 2, Fig. 1, is mounted axially in a highly-exhausted tube, and passes through an annular anode 6. A closelywound helix 7 forming the space-charge neutralizing-electrode is mounted close to the wall of the tube, and is maintained at a positive potential by a battery 8. A potential gradient in the electrode 7 similar to that in the cathode is produced by means of a battery 9 so that the radial field due to the electrode is constant along the length of the cathode. A helix 15 mounted around the tube creates a magnetic field parallel with the main electron path to the anode, this field serving to prevent the passage of electrons to the electrode 7 and causing the electrons to move in curved paths around the cathode. The electrode 7 and the cathode may be connected with a winding forming the secondary of a wireless receiving circuit 17, the anode and the cathode being connected with a telephone or other receiver 14. It is stated that the current in the anode circuit increases very rapidly with an increase of potential of the electrode 7, but falls off slowly with reduced potential. In an arrangement, shown in Fig. 3, for the production of alternating current from continuous current, a cathode 27, mounted at one end of a tube, is surrounded by a cylindrical neutralizing-electrode 21 having an annular extension 28 tending to produce an axial discharge of electrons. The anode is in two parts 29, 30 connected with the primary winding 38 of a transformer, the neutral point of which is connected through a continuous-current generator 41 with the cathode. In addition to a helix 31 for producing an axial magnetic field, a magnet 32 energized by windings 35 excited by alternating current is arranged to produce an alternating magnetic field transverse to the electron path. The electrode 21 is maintained at a high positive potential. The field due to the magnet 32 causes electrons to pass alternately to the anodes 29, 30, thus producing an alternating current in the transformer. In a similar arrangement, the magnet 32 is omitted, and an alternator is connected between an axial cathode and a controlling-electrode, an annular electrode being connected through the primary of a transformer and a pulsating-current generator with the cathode; it is stated that alternating currents are produced in the secondary winding of the transformer. The neutralizing-electrode may be mounted outside the tube.

Abstract: 669,826. Curve -- drawing instruments. THOMAS, R. E. July 27,1949 [July 27,1948], No. 20061/48. Class 97 (iii). A device for generating the arc of a circle about'an inaccessible centre comprises a pair of spaced pivots 6 whose axes intersect the chord of the arc, a pair of rigid guide members 8, 9 mounted to swing about these pivots to define the locus of the apex of a triangle constructed on the chord as base and having a constant apex angle, a drawing point or tool 22 supported by the guide members at that apex, means for adjusting the height of the triangle and means for differentially varying the effective lengths of the sides of the triangle whilst maintaining constant the apex angle. As shown, the latter means comprise a two part carriage 12 having members 10a, 11a, slidable along each guide member 8, 9 which are adjustably clamped together at the required apex angle, the guide members being located in adjacent parallel planes so that one overlies the other at the apex of the triangle. The pivot members 6 may be mounted on a rigid base member 1 and the means for adjusting the height of the triangle may comprise. a bar 25 graduated in terms of the radius of the arc and mounted perpendicular to the base member 1 at its midpoint. The end of the bar 25 may co-operate with an anvil provided on the carriage 12 at the apex of the triangle. In a modification the guide members are pivotally connected to each other at the apex of the triangle and are slidable lengthwise in relation to the axes of their respective pivots. The pivots are either in the form of guiding sleeves or carriages at the end of a rigid spacer member, and in the latter case the ends of the guide members remote from. the apex may be connected by a member which is adjustable for length to determine the angle between the guide members at the apex of the triangle.
