Title: Photoconductive pick-up tube and method of manufacture
IPC: H01J9/26
Filed: 1958-02-26
Abstract: 889,027. Television pick-up tubes. RADIO CORPORATION OF AMERICA. Feb. 26, 1958 [March 25, 1957], No. 6284/58. Class 39(1) In a television pick-up tube having a photoconductive target 28 scanned by an electron beam, the optically flat polished face plate 31 of the tube is sealed to the main envelope portion 12 by means of an interposed ring of indium 42, the seal being made solely by the application of axial pressure without heating at all or at least without heating sufficient to melt the parts. The indium ring 42 has opposite 45 degrees bevels so as to have a triangular cross-section and is centrifugally cast when in a molten state on to the inside of a brass or stainless steel ring 40 and then trimmed to form the bevels. If 40 is of stainless steel it is copper plated before the indium is deposited. The axial pressure of 600 1bs./sq. inch (e.g. 170 lbs. for the envelope cross-sectional solid area) applied while the parts are held in a jig squeezee in each side of the indium ring to form a T-shaped cross-section as shown in Fig. 2(d) the leg of the T forming an electrical contact for the conductive transparent underlayer 33 of tin oxide or tin chloride. The envelope shell end is ground flat, polished and cleanedbefore the seal is made to the face plate. The face plate is of glass or ceramic formed as an optically flat window by grinding and polishing followed by cleaning with chromic acid, rinsing with distilled water and baking to remove grease. The signal layer 33 is coated so as not to reach the periphery of the face plate and the photoconductive layer of uniform thickness 32 covers part of the area of the signal layer and no area outside it. The precise areas of layers 32, 33 are controlled by apertured masks. The signal layer and photoconductive layer are deposited before the face plate is sealed to the envelope. The indium seal must be formed at a temperature of less than 155‹C. (the melting point of indium) and if the photoconductive layer is of antimony trisulphide, of less than 150 degrees to avoid harming the latter. The photoconductive layer is made by evaporation in an argon atmosphere at a pressure of 1 mm. Hg. to cause the layer to be porous. During subsequent processing of the tube the indium seal and photoconductive layer must be kept cool e.g. by blowing air on to the face plate. Alternatively the gun is sealed in first, then the indium seal is made, then the final processing is carried out. The focusing and deflection means are magnetic. The electron beam is accelerated by three tubular electrodes and scans the photoconductive screen through a fine mesh screen. An exhaust tube is built into the gun end of the tube. The indium ring may be a lead for the transparent tin oxide or tin chloride layer.

Title: Improvements in devices for controlling furnaces
IPC: F23N1/00
Filed: 1932-03-07
Abstract: 398,198. Furnace-control apparatus. SMITH, G. W., 1121, Wightman Street, Pittsburg, U.S.A. March 7, 1932, No. 6797. Convention date, March 7, 1931. [Class 51 (i).] A port or duct 10 leads from the furnace chamber 2 to a cooler region, e.g. the atmosphere, so that variation of gas pressure in the furnace causes a flow of air or hot gases into or out of the furnace, the resulting changes of temperature in the duct affecting a heat sensitive element 9 which controls means such as a chimney damper 4, the fuel supply or the air supply for restoring the pressure. To maintain pressures other than atmospheric in the furnace the pressure in the duct 10 may be varied. A tube 12 in the duct 10 carries the thermostat 9 and is open to the atmosphere through a lateral flared tube 14. Change of temperature in the duct causes the rod 67 of the thermostat to operate a lever 57, Fig. 2, to move a valve 83 controlling the supply of compressed air to a pipe 55<1> connected to the bellows 41 of a regulator 5 operating the damper 4. AT-pipe 15 in the tube 14 with valves 16, 17 supplies compressed air for varying the pressure in the duct 10 to correspond with any desired pressures in the furnace. To maintain the furnace pressure above atmospheric the valve 17 is opened, while for pressures below atmospheric the valve 16 is opened and the valve 17 i closed. Alternatively the duct 10 may lead to a closed chamber in which the pressure can be regulated. The thermostat comprises a tube 66 enclosing the rod 67 and carrying a knife edge 77 engaging the lever 57 which is pivoted at 58 and carries an adjustable bolt 81 operating the relay valve 83 which controls the supply of air from a pipe 55 to the pipe 55<1> leading to the bellows 41 and also controls an exhaust port 93. To adjust the thermostat initially the knife edge 77 is released, the thermal element allowed to come to a temperature corresponding to atmospheric pressure in the furnace and a nut 79 turned until the knife edge seats upon the lever 57 in which position it is locked by a bolt 80. The bellows 41 operates, through a rod 45 and link 28, a valve 24 supplying pressure fluid to a cylinder 18 in which slides a piston connected to cross heads 21, 21<1> connected to the damper 4 by a link 23. An adjustably inclined bar 36 moving with the crosshead 21 operates a lever 33 to close the valve 24 after the piston has travelled a predetermined distance, so that the valve is adjusted in incremental steps. Electrical relay apparatus may be used.
