Title: Improvements in or relating to electric discharge devices
IPC: H01J17/52
Filed: 1936-12-23
Abstract: 480,208. Discharge apparatus. WESTINGHOUSE ELECTRIC & MANUFACTURING CO. Dec. 23, 1936, No. 35312. Convention date, Jan. 4. [Class 39 (i)] An electric discharge device, preferably gas- or vapour filled, has a thermionic cathode 25, an anode 6 and a foraminated guard member 33 coated with emissive material disposed adjacent the cathode for blocking the passage of current until the cathode is at a predetermined temperature, the guard member being surrounded, preferably concentrically, by at least one radiation shield 41 so positioned that a narrow pocket is formed between the guard and shield members which is closed except for a small opening at the top through which electrons pass to the anode. In the form shown, the directlyheated cathode is a corrugated ribbon wound on a toothed or threaded insulator 27, and is mounted, together with the perforated guard 33 and two heat shields 41, 51, upon top and bottom insulators 61, 36. The outer shield 51 acts as a return lead for the cathode, to the top end of which it is connected by the metal cap 30 closing the end of the guard 33 and supporting the cathode insulator in recess 31. The control grid has a cylindrical portion 8 supported at the bottom by insulator 61 and at the top by clips 11 engaging the domed envelope 3, and a flat portion 9 extending between the anode and the pocket. The insulator 61 has annular grooves to increase the leakage path from cathode to grid. The guard 33 is coated internally or externally with emissive material and is preferably connected to the negative end of the cathode but may be slightly positive. Initially, the guard 33 confines the electrons emitted by the cathode and prevents a discharge passing, but when sufficiently heated by radiation from the cathode it emits electrons which produce ionization in the space between it and the anode. The positive ions thus formed pass inside the guard and neutralize the space charge therein until the discharge passes. The cathode may be a flat ribbon or a filament. The Specification as open to inspection under Sect. 91 referred to Specification 24432/36. This reference does not appear in the Specification as accepted.

Abstract: 507,243. Centrifugal gas - cleaners. THUILLARD, L. Dec. 21, 1937, No. 35349. Convention date, Dec. 24, 1936. [Class 23] Gases are cleansed from impurities by being subjected to centrifugal action anc then to passage through a decelerat ing zone before being discharged to the at mosphere. The appar atus employed is shown attached to a smoke stack 1; it consists of a main conduit 2a attached to the stack and ter minating at its upper end in three return bent passages 2 which open into the chamber 3. The centrifuga action in the curved path and the deceler at ion in the chamber 3 cause the solid impurities in the gas stream to drop to the inclined floor 5 and the discharge pipe 6. The upward flow of the gas to the space beneath the cowl 10 is deflected by baffles 8, 9 which slope in opposite directions and have flanges to retain any light solids tending to follow the gas. The baffles 9 can be moved by means of chains 11, 12, and the rods 14 can be rocked against the baffles 8 so that particles collected on the baffles can be made to drop. The clean gas can be passed through an axial discharge pipe instead of being discharged under the cowl.

Title: Polarizer and method of making same
IPC: G02B5/30
Filed: 1932-12-16
Abstract: 412,179. Optical polarizers. LAND, E. H., Wellesley Farms, P.O. Box 22, Middlesex, Massachusetts, U.S.A. Dec. 16, 1932, No. 35742. [Class 97 (i).] A polarizing body comprises a set suspending medium containing a multiplicity of dispersed minute particles having polarizing properties, the particles being oriented so as to have their axes of polarization substantially aligned. A suitable polarizing material is herapathite and a suitable suspending medium is a solution of nitrocellulose. According to one method described, a gel-like mass of herapathite particles is obtained by dissolving 1.5 gm. of quinine bisulphate in 50 cc. of methyl alcohol, boiling and stirring, and while stirring adding À525 gm. of iodine in the form of a 20 per cent solution in alcohol. On removing the heat and continuing to stir the herapathite precipitates as a gel. This is introduced into a viscous nitrocellulose solution and stirring is continued until a uniform colloidal suspension is secured, the particles of the herapathite being of such small size that at least their smaller dimension is less than the wave length of light. In order to orient the particles to align their polarizing axes, the viscous mass is subjected to a force, which may be mechanical or electrical, to which the particles are susceptible. For example a sheet of the viscous material may be sandwiched between two much thicker sheets consisting only of the suspending material and the whole extruded through a slit like die positioned in alignment with the central layer, thus subjecting the polarizing particles to stretch which produces the desired alignment. Alternatively the orientation may be effected by subjecting the suspension to an electric or magnetic field, preferably after diluting the suspending medium. The material after treatment as above described is allowed to set.
