Filed: 1948-02-27
Abstract: 654,588. Discharge apparatus. SYLVANIA ELECTRIC PRODUCTS, Inc. Feb. 27, 1948, No. 6186. Convention date, Nov. 30, 1946. [Class 39 (i)] In apparatus, such as a cathode-ray tube or a mass spectrometer, having crossed magnetic and electrostatic fields for separating particles of a given ratio of charge to mass from a beam of charged particles, the pairs of elements producing the fields are so shaped that, when energized in predetermined proportion, the deflecting effects of the two fields on the selected particles are mutually cancelled at every point on the beam axis. In the preferred form, a cathode-ray tube is provided with gun 14, fluorescent screen 24 and an ion trap comprising magnet 26 and deflecting plates 34, whereby ions are deflected out of the electron beam to impinge on the disc 25. The plates are connected to potentiometer 42, the mid-point of which is connected to the coating 12 of material, known under the Registered Trade Mark " Aquadag," which ensures a uniform electrostatic field in the vicinity of the trap. Local deflections of the beam within the trap with consequent beam distortion are eliminated by shaping the plates, e.g. as shown, to conform as near as possible with the magnetic lines of force generated by rectangular polepieces; alternatively, the shape of the plates may first be determined and the polepieces subsequently designed. The electrostatic fields may be computed by immersing the plates, connected to a suitable potential, in an electrolyte. Specifications 505,632 and 538,684 are referred to.

Title: Improvements in fluid blast electric circuit breakers
IPC: H01H33/985
Filed: 1941-05-16
Abstract: 544,798. Gas-blast switches. BRITISH THOMSON-HOUSTON CO., Ltd. May 16, 1941, No. 6348. Convention date, May 16, 1940. [Class 38 (v)] A gas-blast switch is provided at the interrupting-arc with a definite quantity of blast-gas produced by the evaporation at a series-connected, pressure-producing break of a measured quantity of liquid, such as dichlordifluoromethane, water, or carbon tetrachloride. The part of the switch at the main-break contacts 10, 11 is constructed as in Specification 544,017, the blast being admitted through conduit 24 from a gas accumulator 21 forming part of a gas generator 18. , The pressure-break, comprising a movable contact 16 on a piston rod 30 co-operating with a movable contact 15 sliding in a tubular arcing-contact 39 for limiting the arclength, is shown in open position in Fig. 2. Liquid 26 passes from the reservoir through hole 31 into a cylinder 28 in which is a piston 27 on rod 30 having an aperture and flap-valve (not shown) which, when the piston 27 is depressed, allows a measured quantity to pass through into the upper part of the cylinder 28. The rod 30 has a hole at the bottom leading into a through-bore (not shown) through which, when the pressure-break is formed, the measured quantity is fed to that break. The piston 27 is spring-urged in the opening direction, but the arrangement acts as a dashpot to retard contact 16, so ensuring an immediate and continuous production of gas. If the switch opens on no-load, a hole 45 permits the liquid to flow back to the reservoir at the next closure, and the amount of liquid can be adjusted by a screw 28a. On light loads the small amount of gas generated will be sufficient to deal with the small interrupting-arc. A pressure-equalizing vent 40 allows ready transfer of liquid from cylinder 28 to the pressure-arc; but by restricting or removing this vent, the pressure in the accumulator may be kept substantially constant for currents above a predetermined value, since it is balanced against the force of spring 37 and can arrest the piston 27 until relieved at conduit 24. In Fig. 3, a spring-urged intermediate contact-member has a contact surface 47 cooperating with movable contact 46 to form the main arc, a stop 63 limiting its upward movement, and a contact-part 51 co-operating with the upper end of piston rod 52 to form the pressure-arc. Baffles 49, 50 and aperture 62 direct the blast. Liquid flows into cylinder 54 via pipe 61, passes through orifice 55 and flap valve 56 to the upper part of cylinder 54 and thence through hole 57 into bore 58 and on to the arc.
