Title: Improvements in methods of making electron tubes
IPC: H01J21/36
Filed: 1958-05-13
Abstract: 868,547. Thermionic valves. EITEL-Mc- CULLOUGH Inc. May 13, 1958 [Sept. 19, 1957], No. 15359/58. Class 39(1). [Also in Group XXII] In a method of making a discharge tube, each of at least two electrodes is formed on a support so as to have a predetermined position relative to indexing means provided on a part of its support, which is to be external to the envelope and the supports and intervening envelope parts are bonded together with the indexing means of the two supports having a predetermined position with respect to each other. As shown in Figs. 1 and 9, each of the grids 22, 23 is formed (see Group XXII), so as to have one of its equally-spaced longitudinal wires located on a radial line passing through the centre of an indexing tab 36<SP>1</SP> on its support 26 or 24. Indexing tab 36<SP>1</SP> is a marked one of the electrode terminal tabs 36. The electrodes 21-23 on their supports 9, 11, 12, together with alumina envelope parts 2-4, 6, 7 and heater terminals 33, 34 and supports 31, 32 are assembled in a jig comprising base plate 90, cylindrical wall 92 and separate spacing keys 100, the indexing tabs of the two grids being one above the other. Anode sealing ring 16 and, if desired, anode 13 sealed to ring 14, are placed on top of the jig. The envelope parts having been previously metallized by a molybdenummanganese powder sintering process, and copper-gold brazing rings having been inserted between all the parts which are to be sealed together, except between cathode support 9 and its adjacent envelope parts, the assembly is then passed through a brazing oven. Afterwards the cathode is coated, the heater is secured to its supports and the parts are reassembled with brazing rings on each side of support 9 where a local radiation braze is effected. If the anode has not been previously sealed to the remainder of the tube, a final local braze or weld is made at 17. In a further embodiment, Figs. 10 and 12, a cathode heater and five planar electrodes are supported on rings 117-123 each provided with a single terminal tab 117<SP>1</SP>-123<SP>1</SP>. Each grid is formed with its wires having a predetermined position relative to its terminal tab so that when the electrodes are assembled in a jig comprising base plate 154 and cylindrical side wall 158, with their terminal tabs in a respective one of the grooves 159 in side wall 158, the wires of the three grids are in alignment. If the electrode supports are formed with terminal rings instead of tabs, the indexing means may comprise notches in the peripheries of the rings, co-operating keys being provided in the assembly jig.

Title: Improvements in slipping preventing devices for vehicle wheels
IPC: B60B39/00
Filed: 1920-06-10
Abstract: 168,685. Chism, W. J. June 10, 1920. Slipping-preventing attachments to wheels.- Relates to slipping-preventing attachments of the kind comprising radially movable spuds mounted at the side of the wheel and held in contact with the ground by the action of springs, and means for withdrawing and retaining the spuds out of action at the will of the driver of the vehicle. The invention consists in the provision of a guide-ring 12 for the spuds which is secured directly to and in spaced relation with the felloe either by bolts 15 and distance-pieces 16 or by brackets. In the former arrangement, bracing-rods 60, the ends of which are disposed on adjacent bolts on opposite sides of the distance-pieces, may be provided. The spuds may be formed of two pieces of stamped metal combined as shown in Fig. 4, the ground engaging part 19 being disposed obliquely to the wheel plane. Serrated calk members 62 may be fitted over the parts 19. The arm 18 works in a slot 13 in the guide-ring and is held at different heights by a stop placed in one of the apertures 22. The stops used consist of a cylindrical block 21 which carries a bent steady-pin 29 adapted to engage a small-opening in the arm 18 adjacent the hole 22 and is secured in a readily detachable manner by a bent spring-pressed pin 26, the end of which is adapted to lie behind the arm 18 or in the recess 23. The arms 33 move in pockets 32 which contain adjustable compressed springs 37 by which the spuds are actuated. A frame 44, Fig. 10, is pivoted on the vehicle frame so as to swing at right-angles to the wheel plane, and is actuated from the driver's seat through the lever 58, rod 57, and a combination of bell-crank levers. The upper end of the frame carries a cam 45 which when brought into the path of the stops 21 withdraws the spuds successively within the periphery of the wheel tyre, in which position they are retained by spring latches 47 engaging the stops. The tail end 49 of the frame 44 is adapted to trip the latches and release the spuds. In the intermediate position of the frame, both parts are free of the wheel.
