Title: Improvements in the productions of ion beams
IPC: C25D3/24
Filed: 1952-04-10
Abstract: 713,993. Heavy-ion-beam tubes. BENDIX AVIATION CORPORATION. April 10, 1952 [April 18, 1951], No. 9295/52. Class 39(1) In an apparatus fo producing sharply defined intense pulses of positiv ions such as for use in mass spectrometer, the ions are produced by th ionization of molecule introduced into the path of an electron strearr and are retained by th electric field or potentia well created by the electron stream. When a maximum or desired concentration of ions is obtained the electron stream is reduced in strength or cut off, and the ions are then withdrawn in a pulse or bunch at a predetermined time relative to the reduction in strength or the cutting off of the electron stream. As shown the electron beam is generated in a housing 54 by a tungsten filament 56, accelerated through control and accelerating electrodes 58 and 64 into a housing 72 where it produces ions by collision with the gas molecules introduced through a slot 84, and finally collected by an electrode 100. To one side of the housing 72 is a grid electrode 80 for controlling the ejection of the ions. The housings 54 and 72 are mounted on a common base. The electrodes 58 and 64 are mounted by means of glass studs, and mica washers between the housings 54 and 72. The filament leads are clamped to an insulating plate screwed to the base of the assembly The insulating plate may be released from the base for vertical adjustment of the filament 56, and the filament may also be adjusted laterally and axially by relative movement between the assembly 54-72 and the base by the use of screws. Preferably a magnetic field is applied in the same direction as the electron flow to assist in forming and maintaining a thin stream of electrons. The ion source is particularly applicable to a mass spectrometer in which ions of differing mass derived from the different gases in an unknown mixture, rotate through circular paths in a constant magnetic field, and the various masses are determined by measuring the times of flight of the various ions.

Title: Improvements in and relating to spark gap devices
IPC: H01T1/04
Filed: 1956-03-26
Abstract: 793,483. Protective arrangements: GENERAL ELECTRIC CO. March 26, 1956 [March 24, 1955], No. 9361/56. Class 38 (4). A spark-gap device of the kind disclosed in Specification 698,583 is modified so that the terminals of the main spark gap are situated at the outer ends of. the main electrodes and the last electrode of the auxiliary electrode system is so constructed that the reverse magnetic field tending to prevent the arc from travelling towards the outer ends of the auxiliary electrodes is reinforced. The main spark gap 16 is situated between main electrodes 14, 15, the terminals thereof being constituted by bolts 17, 20. The auxiliary electrodes 21-32 are placed in pairs to one side of the main electrodes and the last electrode 44 of the auxiliary electrode system is placed by the side of auxiliary electrodes 26, 32. The auxiliary electrodes 21-32 are each comprised of a metal strip bent into a narrow U- shape see Fig. 6, the sides of the U being insulated from each other. The electrode 44 is formed from a metal strip bent at two places to form a double U shape, also with the sides of the U's insulated from one another. Thus when a spark is initiated at the main gap 16 and is driven into the auxiliary electrode system by the magnetic field of a coil 61, which it separates into a number of sparks, current flows around the loops of the auxiliary electrodes, thereby, together with the return field of the coil 61, preventing the are from travelling outwards along the auxiliary electrodes to the ends thereof. Pre-ionizing means for the main gap are provided and are connected in parallel therewith by means of straps 74, 75. The connection is by means of capacitors which thereby reduces the interference the device causes with radio apparatus. The pre-ionizing means comprises one or more capacitors 102 which enclose a resistor 103 or an inductor and a pair of corona emitting electrodes formed by the flanges 114 of the bell-shaped members 105. In other embodiments the dielectric of the capacitor or capacitors is formed by the insulating members 12, 13 carrying the electrode systems and the resistor may be formed by metallic paint on the surface of the members 12, 13.

Abstract: 348,310. Brakes. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Warner Electric Brake Corporation ; 449, Gardner Street, South Beloit, Illinois, U.S.A.) March 27, 1930, No. 9829. [Class 103 (i).] Electric and magnetic; band ; applied by running axle or wkeel.-An electromagnetic friction-device, comprises a pair of annular magnetic elements arranged for relative rotation and forming a closed magnetic flux circuit around each circumferential section of an annular energizing-winding carried by one of the elements, is provided in the magnetic element which does not carry the winding and thus constitutes the armature, with a single non- magnetic section of substantial circumferential length to constitute the means to dissipate the magnetic flux residual in the elements upon de-energization. This non-magnetic section interrupts the continuity of the armature surface so as to be presented to the successive sections of the magnet face during each revolution. In the example shown, an air gap is formed by a radially-extending depression 32 in the armature ring 19 of a vehicle wheel brake. This brake comprises a band 15 adapted to be expanded against the drum 6 by the magnet ring 20 when this is energized and frictionally grips the armature ring 19 attached to the brake drum 6 rotating with the wheel. The band 15 encircles a flange 14. Fittings on the adjacent ends of the band 15 are drawn against the opposite ends of a stop by a spring. Lugs on these fittings are adapted to be engaged by two actuating-lugs projecting radially from the outer pole of the magnet ring 20. The ring 19 is supported by strips extending tangentially to the ring and rigid with a ring 22 riveted to the drum 6. These strips prevent movement of the ring 19 in one direction and arms 25 on the ring engaging slots in the ring 22 prevent movement in the other direction. The ring 19 is pressed lightly against the ring 20 by springs 24. The ring 20 is U-shaped in cross section with the winding and also non-magnetic rear plates 28 between the concentric poles 27. The ring 20 oscillates on a flange 29 of the anchor plate.
