Title: Improvements in and relating to high frequency generators of the travelling wave type
Inventor: DUNSMUIR ROBERT
IPC: H01J23/24
Filed: 1956-06-22
Abstract: 835,417. Travelling-wave tubes. BRITISH THOMSON-HOUSTON CO. Ltd. June 21, 1957 [June 22, 1956], No. 19425/56. Class 39(1). A travelling-wave tube includes a slow wave structure comprising a plurality of electrically conducting plates L extending transversely of the electron beam path. The plates are insulated from each other and spaced apart along the beam path, e.g. by insulators M, so as to form an array of resonant cavities the fields whereof interact with the electron beam at successive positions so as to produce a transfer of energy therebetween in a manner to amplify R.F. waves projected along the structure. This structure presents a high coupling impedance to the beam and also permits an axial D.C. electric field to be applied to the beam. This field may be arranged to be uniform either by making the capacities between the discs L equal or by using high resistances between the discs. Alternatively the field may be graded to be greater at the output end, where the electron retardation due to R.F. is greatest, by grading the resistors or by bringing in intermediate potential connections to the discs. The resistors may also be used to provide the required R.F. attenuation or a separate R.F. attenuator can be provided. In an alternative arrangement to that shown the plates L of the slow wave structure may be rectangular and may be spaced along an axis parallel to the beam path, but displaced laterally therefrom, Fig. 1 (not shown), provided of course that the structure is near enough to the beam path for the resonant cavities to interact with the beam. Preferably the resonant cavities are so shaped that the field between adjacent plates operates in a mode such that the electric field has a maximum field strength at opposite edges with a single node between. Suitable coupling may be provided between the resonators. Specification 782,573 is referred to.

Title: Improvements in method of forming molds for printing plates and molds formed thereby
IPC: B41C3/00
Filed: 1928-07-09
Abstract: 312,532. Claybourn, L. W. July 9,. 1928. Printing-surfaces.-To prevent certain parts of electrotype or other thin printing-plates from being injured, when pressed against a flat surface to level up the printing-surfaces, or when bent around a cylinder and acted on by pressure for the same purpose, the surfaces are formed with bearer areas of the same height as the printing- surfaces, and these areas take the pressure and prevent injury to the printing areas. The bearer areas may be subsequently removed by routing tools before the printing operation. The printing- surfaces are cast from moulds 42, Fig. 6, such as wax moulds on a metal base, and after the design to be printed has been impressed into the mould, the bearer areas are formed by cutting out grooves 51, Fig. 14, in the mould by means of a cutting tool 53 formed with a sharp bottom and sides and with curved front parts 55, 56 which facilitate the removal of waxed strips. The mould is clamped to a table while the cutter acts, and means are provided for adjusting the cutter in a plane perpendicular to the plane of the mould and for setting it at the same height as the bottom of the depressions produced by the printing-surfaces. The tool or table is traversed to cut out desired areas, such as rectangles, and when the printing-surface is cast, bearer areas 38, Fig. 13, of the same height as the printing surfaces 31 are formed in the moulded plate. Rough edges produced by the cutting-tool may be removed by momentary application of heat. After the printing-plate has been trued up on a flat surface or a cylinder under pressure, the areas 38 are removed by a routing tool.
