摘要： 484,511. Ornamenting. ROGERS RADIO TUBES, Ltd. Dec. 23, 1936, No. 35251. Convention date, Jan. 11. [Class 93] [Also in Group XX] A coating of powder is formed on a surface as of metal or glass, e.g. a luminescent coating on a cathode-ray tube, by cleaning the surface, exposing it to the products of incomplete combustion of a compound of sulphur in order to form by condensation a layer of sulphur on the surface, dusting finely powdered material evenly on the layer, removing excess of powder, and then heating to evaporate the sulphur layer, so that the powder coating is left adhering directly to the surface. The Figure shows an apparatus wherein the end of a cleaned cathode-ray tube is coated with sulphur produced by burning carbon bisulphide contained in a holder 4 heated electrically by a coil 5, in a slow draught produced by an aspirator attached at 8, the products of combustion being drawn up a tube 2 with a jacket 7 leading to the aspirator tube 8 and being dispersed over the end wall of the ray tube 1 by a plug 6 on the top of tube 2. After wiping off any undesired sulphur at the edge of the layer, powdered luminescent material such as synthetic willemite activated with manganese, or zinc sulphide from which copper and other impurities have been removed, is dusted on evenly the excess wiped off, and heat applied to evaporate the sulphur. Specification 458,635, [Group XX], is referred to. The Specification as open to inspection under Sect. 91 states also that the condensation layer may be formed by exposure to the products of incomplete combustion of compounds of other elements. This subject-matter does not appear in the Specification as accepted.

摘要： 450,063. Thermionic valves. ROGERS RADIO TUBES, Ltd., 100, Sterling Road, Toronto, Canada. Oct. 19, 1935, No. 28925. Convention date, Nov. 6, 1934. [Class 39 (i)] A valve has a high mu triode section in the upper part of the envelope 1 and a power pentode section 30 in the lower part both supported from the press 32 provided with a cap 2, which carries the contact prongs 3- 9 ; two transverse metal plates 19, 20 screen the two sections from one another, and are welded to two standards 23 24. A common cathode body 13-with internal heater-has two separated coatings 14, 15 of emissive material; the upper end of the cathode body is connected by a lead 25 to the standard 23, the lower end to the standard 24, and the pentode shield grid to the standard 23, so that this grid, the cathode body and screen plates 19, 20 are electrically connected. Resistance coupling between the two cathode coatings is dispensed with. The triode anode 12 has an opening 16, which permits inspection of the triode and facilitates degasification during forming. The grid lead from the triode is taken through the upper end 10 of the envelope; the anode lead consists of a small diameter tungsten wire 27 coated with aluminium oxide or other ceramic material and passes through an aperture in a mica spacer 28 for the electrode structure. The spacer is stayed by a strut 35 from the pentode anode. A cooling vane 31 is welded to the standard for the control grid of the pentode. The envelope has a metal coating 41 such as described in Specification 414,193.

摘要： 431,019. Thermionic valves. ROGERS RADIO TUBES, Ltd., 100, Sterling Road, Toronto, Canada. Oct. 26, 1934, No. 30728. Convention date, Dec. 1, 1933. [Class 39 (i)] A multiple valve comprises one electrode system, such as a pentode, having one or more screen grids including an accelerating grid 4, Fig. 3, and a full wave rectifier of which the cathode 20 is connected to the accelerating grid. For convenience the rectifier comprises two cathodes each co-operating with an anode 10, 11 and electrically connected. As shown in section in Fig. 2, each cathode 20 is surrounded by a ceramic tube porous to electrons and enclosed by cylindrical portions of the anodes 10, 11 which are placed side by side with flat portions parallel with and juxtaposed to the main anode 6. An electrostatic screen in the form of a ferrule closing the top of the electrode system minimizes hum due to the alternating potential impressed on the rectifier. The heaters 8, 9 of all the cathodes are connected in parallel.

摘要： 446,606. Thermionic valves. ROGERS RADIO TUBES, Ltd., 100, Sterling Road, Toronto, Canada. April 26, 1935, No. 12529. Convention date, April 26, 1934. [Class 39 (i)] In an electron coupled thermionic oscillator the central triode oscillator section comprises an indirectly heated cathode 19 an anode formed of two coupled rods 18, 20 and a grid 17 outside both anode and cathode, the grid having reentrant parts as described in Specification 445,738 so as to-in partenclose both the anode and cathode. This position of the grid prevents conductance between the screen grid 16 and anode 18, 20 causing cessation of oscillation of the triode. A logarithmic control grid 15 for the output section surrounds the screen grid 16, and between the grid 15 and output anode 13 a further screen grid 14 is provided, the two screen grids 14, 16 being connected together. The control grid 15 has a lead 12 to an upper terminal 1 on the envelope shielded by a metal mesh screen 33 ; the remaining electrodes and heater connections are taken to contact prongs 4 ... 10 on the base. The electrodes and screens are spaced by two ceramic plates 21, 22 ; a mica plate 23 is used at the upper part of the assembly to position the electrodes in the envelope ; this mica plate has a central orifice so that it does not contact with those electrodes which become highly heated during running. A metal coating 24 sprayed on the envelope as described in Specification 414,193 is earthed or at cathode potential.

摘要： 394,165. Thermionic valves. ROGERS RADIO TUBES, Ltd., 100, Sterling Road, Toronto, Canada. Aug. 19, 1932, No. 23356. Convention date, March 15. [Class 39 (i).] The cathode cylinder 9 has a part of its surface covered with electron-emissive material surrounding an insulator 12 and heater 10; the remainder of the cylinder extends upwardly and screens the wire 6 leading from terminal 5 to the control grid. The lead-in is surrounded by insulation 8 and a glass bead 7 is sealed on to it to prevent contact where it emerges from the cylinder. The anode 21 has a slot 25 bridged by a hairpin wire 24 so that the high frequency field used in heating the electrodes to free them from gas during manufacture may quickly penetrate to the inner electrodes. The outer surface of the valve may be zincsprayed and connected to the cathode or a screen may closely surround the anode. The control grid is wound on posts 18, 19 and the screen grid on posts 16, 17 which carry a metal ferrule 28. Mica washers 15, 29, the latter resting on ferrule 28, position and space the cathode, control grid and screen grid, and the whole structure is supported on posts 13, 14 to which the ferrule 29 is welded.
