Patent GB-488920-A (GB)
Title: Improvements in or relating to electron-optical systems
IPC: H01J31/28
Filed: 1936-11-30
Abstract: 488,920. Discharge apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 30, 1936, No. 15324/38. Convention date, Nov. 30, 1935. Divided out of 489,846. [Class 39 (i)] An electron-discharge device comprises an electron-emitting surface or cathode upon which an image of an object is adapted to be projected and which causes the emission of an electron image of the object, and an electron lens for focusing the electrons on to a further surface, the electron-emitting surface being concave to such an extent as substantially to correct for pin-cushion distortion which would otherwise result from the electron lens. The cathode 3 is used in the electron telescope described in Specification 489,846, which consists of the cathode, the lens 11 and anode 15, focusing an image on a fluorescent screen 9, or on a mosaic electrode which is scanned by a cathode-ray beam to produce impulses for transmission. The cathode may be so arranged that the impinging radiation reaches the emitting surface directly in which case it need not be transparent, and it may be a secondary electron emitter. When the optical image is projected on to the side of the cathode opposite to the electron emitting surface, distortion may be present due to the formation of an image on the curved cathode surface and this is corrected by rendering the non-emitting surface suitably convex so that the cathode itself acts as a lens and produces a focused light image on the electron-emitting surface. Reference has been directed by the Comptroller to Specification 454,832.

Title: Improvements relating to the protection of electric power systems
IPC: B23K9/10
Filed: 1943-09-20
Abstract: 569,986. Indicating faults. RIDDLE, W. H., WRIGHT, D., METROPOLITANVICKERS ELECTRICAL CO., Ltd., and AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Sept. 20, 1943, No. 15406. [Class 37] [Also in Group XXXVII] A signalling or protection arrangement, operative on failure of one of a pair of ignitrons, reversely-connected in parallel, to pass its share of the load current, to give an indication or out off the supply, comprises, Fig. 1, relays A, B in series with rectifiers R1., R2 and indicating lamps L1, L2 across the pair of ignitrons I1, I2. Normally the relays are short-circuited by the latter, but if an ignitron fails, the relay and rectifier of corresponding polarity operate. If A operates, it closes contacts a1 and opens a2, the former energizing relay C which, after a half-cycle, closes at c1 a maintaining circuit for itself and opens at c2 the circuit of an indicator O. Operation of relay B similarly energizes relay D to open contacts d2. A press-button P enables either relay C, D to restore. Lamps L3, L4 indicate which ignitron has failed and lamp L5 the fitness of the source S1, S2, which is preferably rectified and transformer connected to the mains M1, M2. The characteristics of relays A, B are such that when de-energized their contacts remain closed for at least a half-cycle. In Fig. 2, the relays F, G and rectifiers shunt the load and are normally energized by opposing half-cycles. When the system is dead, contacts f1, f3, f4 of relay F are open and contacts f2 closed, and similarly for relay G, but when current is passing the relay-characteristics are such that contacts f1, g1 are held closed, and relay K is continuously energized to hold its contact k1 closed. Should relay F (say) be de-energized, by failure of I1, at the end of the opposing half-cycle, its contact f2 recloses and energizes over contact f3 a relay N, which makes its holding circuit at n1, g4 and at n2 energizes relay U which in turn operates a signal or switch V.
