Title: Improvements in high voltage electric discharge tubes
IPC: H01J5/06
Filed: 1935-10-21
Abstract: 443,697. Discharge apparatus. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Oct. 21, 1935, No. 29021. Convention date, Nov. 14, 1934. [Class 39 (i)] In a very high voltage electric discharge tube provided with one or more hollow intermediate electrodes between the anode and cathodes which interconnect the insulating parts of the envelope, these insulating parts are furnished with re-entrant portions which are secured at their inner edges to the intermediate electrode surrounded by them and which take up part of the potential difference occurring over the insulating wall portions. The invention enables the known " cascaded tubes " to be materially shortened while retaining the same length of surface leakage path. In an X-ray tube, Fig. 2, comprising spherical vessels 7, 8 containing the cathode and anode respectively, re-entrant portions 9, 10 are provided, sealed at their inner edges to the tubular intermediate electrode 11. To avoid arcing between the mouths of the re-entrant parts, cup-shaped insulating shields 12, 13 are provided. In a modified X-ray tube, Fig. 3, the vessels containing cathode 25 and anode 26 are cylindrical, with metal portions 19, 22 which may be connected to points in the system of which the potential is approximately halfway between the electrode 16 and the cathode and anode respectively. Between the re-entrant portions 17, 18 sealed to the intermediate electrode 16 is a shield formed of two semi-cylindrical portions 28, 29 cemented together about the tube 1 and provided with cup-like extensions closely surrounding the insulating portions 21, 23 of the envelope. The intermediate spaces 32, 33 are filled wholely or partly with insulating material, for example, a hardening cement such as litharge. The lead 31 to the electrode 16 passes through the insulator 24. The invention is applicable to discharge tubes for producing corpuscular rays, such as cathoderay tubes.

Title: Improvements in dynamo-electric machines
Inventor: STEPHEN DAVID DOUGLAS
IPC: H02K19/32
Filed: 1960-08-23
Abstract: 922,702. Synchronous machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Aug. 24, 1961 [Aug. 23, 1960], No. 29132/60. Class 35. In change-pole synchonous machines having salient poles, the change of pole number in the salient-pole member is normally achieved only by modification of the excitation of selected poles, e.g. by reversal or suppression. According to the invention, the performance is improved, e.g. made more equal at the two speeds, by modifying the permeance of selected poles to increase the flux-pattern harmonic corresponding to one pole number, without reducing that corresponding to the other. This effect is produced by increasing the relative length of air-gap at those poles which are to be suppressed at the lower pole number, and by the use of pole-shoes which are of different widths or shapes or placed unsymmetrically on the polepieces. The invention may be used to reduce selected unwanted harmonics. Specifications 891,846 and 922,009 are referred to.

Filed: 1923-11-22
Abstract: 207,539. St³tzer, R. Nov. 27, 1922, [Convention date]. Sights and methods of sighting.-For direction finding and indirect aiming, a sighting-device a is trained upon a stationary condensing-lens system d having a measuring-screen e with a wide field graduated in angles to correspond with a scale b movable with the gun or other object to be directed. If the gun is disturbed by the recoil, the difference between the old and new readings on the scale e is noted, and this gives the angle through which the gun and scale b must be turned to restore the correct aim. The scales may be modified to permit of correcting the vertical aim. The open-sight a may be replaced by a telescopic sight the eye-piece of which is furnished with a scale corresponding to the scale b.
