Abstract: ABSTRACT OF THE DISCLOSURE         This disclosure depicts and describes unitized electron guns for color television cathode ray tubes, and is particularly addressed to an improved structural design for elongated electrodes of such guns in which undesired internal interaction between adjacent electron beam-forming fields is prevented.  This sheet metal electrode design also has the advantage of lending itself to economical manufacture.  A relatively axially long unitized electron gun electrode is provided comprising a combination of two outside sheet metal parts and at least one inside sheet metal part.  The combination is axially arranged and conjoined to define three effectively continuous, electrically shielding beam passing tubes extending completely through the electrode, each tube being formed by a contiguous axial succession of deep-drawn annular lips drawn integrally from the inside and outside metal parts.

Abstract: Title of the Invention IRON REMOVAL FROM SOLUTIONS                Abstract of the Disclosure A process for the separation of iron from an aluminum fluoride aqueous solution containing iron is effected by contacting said solution with an organic extractant phase consisting essentially of a mixture of higher alkyl sub-stituted mono- and diphenyl phosphoric acids dissolved in an inert diluent to thereby transfer the iron to said organic extractant phase.  Aluminum fluoride trihydrate is recovered by separating the iron-loaded organic extract from the iron-depleted aqueous raffinate containing the dissolved aluminum fluoride, and subjecting the iron-depleted aqueous raffin-ate separated from the iron-loaded organic extract to a crystallization operation whereby aluminum fluoride trihydrate crystals are produced substantially free of iron impurities.          The iron-loaded organic extract is then contacted with an aqueous solution of hydrogen fluoride to thereby transfer the iron to said aqueous solution and regenerate the organic extractant, and at least a portion of the regenerated organic extractant is recycled back to the first stage of the process to extract iron from the feed alumimum fluoride solution. The efficiency of the process is further improved by adjusting the aluminum fluoride feed aqueous solution temperature to 140°-175°F. prior to contacting it with the organic extract-ant phase, maintaining the temperature within this range through out the iron extraction stages, then heating the iron-depleted aqueous raffinate to a temperature higher than 195°F, and then carrying out the crystallization at this higher temperature.

Abstract: AMPLITUDE RESPONSIVE DETECTOR                ABSTRACT OF THE DISCLOSURE         Disclosed are apparatus and methods for detecting the presence, or absence, of material at a predetermined location. A crystal controlled oscillator generates a constant-frequency, constant-amplitude signal which is fed through a load resistor to an antenna sensor circuit, in-cluding an antenna probe positioned at the sensing location. The amplitude of the signal fed to the sensor circuit varies as the impedence of the antenna probe is affected by material in its environment, or the lack thereof.  The signal amplitude is converted to a d-c voltage level, which is added     to a reference d-c voltage level preset with the antenna probe free of impedance-affecting material.  The difference signal resulting from this comparison is fed to a switching circuit which provides an output signal depending on a comparison between the difference signal and a reference voltage level. A feedback loop in the switching circuit provides a hysteresis effect.  In the method of the invention, a constant-amplitude signal is fed to an impedance bridge which includes an antenna probe whose impedance is affected by its environment.  The amplitude of the signal, thus altered according to the en-vironment of the antenna probe, is used to generate a d-c voltage level reflecting these amplitude changes, and which is added    to a voltage reference level.  The difference voltage level value thus obtained, and which reflects the environment of the antenna probe, is used to control a switching circuit whose output assumes one value or another, depending ultimately on the antenna probe's environment. The output from the switching circuit may be used to operate one or more devices indicating the environment of the antenna probe, and/or affecting the environment by adding to, and/or removing therefrom, material affecting the impedance of the antenna probe.

Abstract: ABSTRACT OF THE DISCLOSURE      An efficient electron emitter cold cathode is formed by first placing an H-type monocrystalline substrate of about 100 at about 500 microns in thickness in a furnace.  The furnace is heated to about 850°C to about 900°C and an N-type layer of about 10 to 15 microns of SnO2 is deposited onto the top surface of the substrate using a suitable carrier gas.  Then, a P-type layer of about 10 microns of SnO2 is deposited on the N-type layer. The furnace is then cooled at a rate of about 10°C per minute to about 600°C to form the emitter.  The furnace is then cooled to room temperature and the emitter removed from the furnace.  The emitter is subjected to etching and polishing to obtain a P-type layer of about 2 to 4 microns, and a nonreactive metal contact is then deposited on the P-type layer.  The emitter is then completed by bonding a metal contact to the base of the N-type monocrystalline substrate.
