Abstract: 704,543. Ion-trapping in cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Feb. 13, 1952 [Feb. 21, 1951], No. 4177/51. Class 39(1) An ion trap gun comprises cathode 2, Fig. 1, modulator 3 and anodes 5, 8 all arranged on a common axis, the aperture 10 in anode'8 being offset with respect to the aperture in anode 5 so that the electrostatic field between 5 and 8 has a transverse component to deflect electrons and negative ions, the electrons only being redeflected by a magnetic field or fields. The magnetic field is produced by internal pole pieces 13 in conjunction with an external permanent magnet. In Fig. 1, in which the electrons are undeviated by the crossed fields the first anode 5 has a flanged cylindrical portion, the pole pieces 13 being secured to flange 7, and second anode 8 has a beam limiting aperture 12. A final anode formed as an envelope coating may be electrically connected to second anode 8. Focusing means such as a coil or permanent magnet is disposed between 8 and the fluorescent screen. An apertured disc serving as an ion stop may be positioned inside anode 8 parallel with and close to wall 11 and may be secured to the inner wall of the anode. In a further form, Fig. 2 (not shown), in which the crossed fields do not balance exactly a further centering magnetic field is provided by a further pair of pole pieces secured to the tubular wall of anode 8 near end wall 9 and co-operating with a further external magnet to ensure that the electrons finally emerge on the axis. Alternatively a single magnet may restore the electrons to a path parallel to their original path. Final beam limiting aperture 12 may or may not be in the centre of end wall 11. In another form, Fig. 3 (not shown), the gun electrodes are all tilted with respect to the tube axis, the crossed fields being such that the electrons finally emerge along the axis. In all forms the gun electrodes are bonded together by insulating rods to form a unitary structure. Examples of potentials, dimensions, and spacings are given. The Provisional Specification states in addition that the final anode wall coating is applied to both the neck and conical part of the envelope.

A thrust bearing comprises a fixed portion 12, Fig. 1 (not shown), and a rotatable portion 11 having opposed thrust surfaces at 11a, main oil inlet means admitting oil to the inner circumference of 11a and main oil outlet means for receiving oil from the outer circumference of 11a As shown, the bearing comprises a thrust collar 11 fixed to shaft 10 and a series of segmental stationary thrust pads 12. The thrust collar 11 also has a cylindrical outer guide bearing surface 11b which engages segmental stationary guide bearing pads 13. An oil inlet pipe 24 communicates with annular duct 25. An outlet 25a of duct 25 is arranged adjacent the opposed thrust surfaces at 11a so that on rotation of collar 11, oil passes between the thrust surfaces. The said oil is then passed through ducts 19 in impeller 18 and hence to oil collecting channel 22 formed in a stationary ring 21. Passage 21a connects channel 22 to an oil outlet pipe 26. A labyrinth oil seal 23 is provided between the ring 21 and impeller 18. Further oil is forced from duct 25 through the ducts 20 to lubricate the guide bearing surfaces 11b and 13a. Oil from guide pads 13<SP>1</SP> passes down as shown by the arrows through passages 27 to the inside face of impeller 18 where it is forced by the centrifugal action of ducts 19 to collecting channel 22 and hence to outlet pipe 26.

Title: An improved indicating device for supervising electric lamp circuits on transport vehicles
IPC: B60Q11/00
Filed: 1952-02-22
Abstract: 691,727. Lamp failure alarms and warning- devices. KEMP, J. Feb. 22, 1952. No. 4724/52. Class 118 (ii). The circuit from a battery 10 to three important lamps 11, 12, 13 on a vehicle is broken at C for the insertion of a supervisory device comprising an electro magnet 18 having a core 19 protruding at each end and provided with pivoted lever armatures 20 and 22 respectively, each spring loaded such that both are moved towards the core when normal current flows in the electro magnet but only one reverts to its off position when the current is reduced by a predetermined amount due to a lamp failure. A spring 24 associated with lever 20 restores the lever to close contacts 40, 41 only when all three lamps 11, 12, 13 fail or a shortcircuit causes a fuse 17 in series with the electro magnet 18 to melt, but a spring 25 acting on lever 22 is adjusted by means of a screw 32 such that the lever 22 closes contacts 26, 27 when all three lamps are functioning but is drawn back to close contacts 26, 34 if one or more lamps fail. The, contacts 41, 27 and 34 are connected respectively to indicator lamps 39, 31 and 38 in a threecompartment casing having differently coloured glasses to provide amber, green and red indications respectively. When all three lamps 11, 12 and 13 are functioning both levers 20 and 22 are attracted to the electro magnet 18 and the contacts 26, 27 cause the lamp 31 to glow steadily. Lamp 31 is of much smaller current rating than lamps 11, 12 or 13 so that the total current through electro magnet 18 is not appreciably increased thereby. If one lamp fails lever 22 is released to make contacts 26, 34 and light lamp 38 which has the same rating as the supervised lamps and consequently the current through electro magnet 18 is restored to the same value as if all lamps 11, 12 and 13 were in order, and hence lever 22 is immediately reattracted to break contacts 26, 34 and make contacts 26, 27. This process continues with the lever 22 acting as a buzzer and the green and amber indicator lamps 31 and 38 flickering. If two lamps .fail the lever 22 is released and does not restore, thereby lighting the lamp 38 (amber) steadily. If all lamps fail with fuse 17 intact both levers 20 and 22 are released and lamps 38 (amber) and 39 (red) light. If fuse 17 is blown the supply to lever 22 is interrupted and only the red indicator lamp 39 lights.

As shown, the part 12 consists of a bar formed with a groove into which the upper edge of the sheet 10 is cemented, or it may be moulded in position on the sheet. Hinge lugs 16 for the temples are formed integrally with the ends of the bar 12, or ordinary metal hinges may be used. A nose-piece 24 may be secured to the sheet 10. In a modification, the bar 12 does not extend to the ends of the upper edge of the sheet 10, and the temple hinge members are separately secured to the sheet. In a further modification, the central portion of the member 12 extends downwardly to form the nose-piece. The sheet 10 may be formed in separate halves.
