Title: Method of treating luminescent materials
IPC: C09K11/02
Filed: 1955-05-26
Abstract: A glass surface, such as the envelope of a fluorescent lamp, is coated by suspending luminescent material in a solution of water, ammonium hydroxide and a copolymer of methyl vinyl ether and maleic anhydride (PVM/MA) in proportions providing a suitable flow viscosity, applying the suspension to the glass surface to form a coating, drying the coating, e.g. by passing hot air downward through the lamp, and then heating it to expel the solution solids.  Part if not all of the solution solids can be removed from the dried coating by flowing water through the lamp.  The mixture can have a pH value of at least about 8, e.g. of about 9 to 10 1/2 .  Alternatively, the luminescent material can be slurried in a solution as set out above and the mixture agitated for a time sufficient to suspend the luminescent particles while maintaining the pH value of the mixture at at least 8, preferably at about 10-10 1/2 .ALSO:Method of manufacturing finely divided luminescent materials comprises mixing the luminescent material with a solution of water, ammonium hydroxide and a copolymer of methyl vinyl ether, and maleic anhydride (PVM/MA), milling the mixture, and then separating the luminescent material from the solution.  The mixture can have a pH value of at least about 8, e.g. of about 9 to 10 1/2 .

Filed: 1924-06-27
Abstract: 227,726. Rude, J. June 27, 1924. Addition to 218,925. No Patent granted (Sealing fee not paid). Producers. - In the generation of water gas from bituminous fuel by use of an auxiliary gas to carbonize the fuel during the blow, and the use of water gas for this purpose during the run, both these gases being preheated before use in the retort, as described in the parent Specification, a pair of heat regenerators are employed each alternately heating the auxiliary gas or the auxiliary gas and water-gas. Fuel from a retort b passes into a water-gas producer f after carbonization by hot gases from a pipe c the distilled products leaving by an outlet d. During the " blow " the gases pass to one of the regenerators h<1>, h<11> being burned in one of the combustion chambers i', i'2 with air from a pipe j. The hot gases then pass to a waste heat boiler l and are discharged to the stack m. During the " run " the water-gas may either take the same path as the " blow " gases and pass by a pipe o to a scrubber or be led away by a pipe p or may be passed by a valve q to the retort for use as a heating fluid. In the two latter cases a gas circuit is maintained by a pipe s and pump t between the pipe m and the combustion chambers i<1>, i<11>. A combustion chamber w in the boiler l acts as a third regenerator and a circuit may be maintained through it by a pipe x additional heating gas being introduced if necessary. The auxiliary gas from a pipe u passes through the regenerator not being heated, continuously or intermittently with the water-gas. The regenerators may also be used as carburettors by supplying them with oil. One distilling retort may be used with several producers in co-operation with one pair of regenerators. The water-gas removed by the pipe p may be mixed with the gas from the outlet d and after cleaning be used as the auxiliary gas. Steam mav be admitted to the hot coke at the bottom of the retort b.

Abstract: 424,780. Treating gases with liquids. DIAMOND POWER SPECIALITY CORPORATION, 10340, Oakland Avenue, Detroit, Michigan, U.S.A. May 29, 1933, No. 15516. Convention date, March 30. [Class 55 (ii)] A series of baffles with grooved or channelled surfaces are arranged at an inclination to the vertical in a horizontal chamber, so that liquid on the rear of the elements tends to flow to the front faces thereof. The baffles 22 are supported by beams 25 above a hopperlike depression 26 formed in the chamber 21 and provided with a liquid discharge valve 28. Liquid may be supplied from a reservoir 30 through nozzles 32 to the interior of each baffle; a guard 221 prevents the incoming stream of gas from flowing over the tops of the baffle. The baffles may be formed with helical threads or grooves as shown in Figs. 3 and 4, or the baffle may comprise a hollow core 43, Fig. 5, and a spiral path 42, liquid being supplied to either end of the core and flowing through radial bores 44 to the spiral. The grooves may be formed on the rear surfaces only, and the front faces may then be fluted or corrugated. In another form of baffle, a tube is twisted so that protuberances extend spirally about its axis ; the ends of the tube may be left circular, and liquid supplied at the lower end of each baffle. The inclination of the baffles may be adjusted in relation of the velocity of the gas by supporting the ends of the beams by trunnions which project through the casing and engage with links connected to a reciprocating bar. The bar carries a piston located in a cylinder to which pressure fluid is admitted under the control of a valve which is actuated by a diaphragm subject to the pressure of gas at the inlet end 23 of the chamber.

Filed: 1958-05-14
Abstract: 1,231,171. Frequency analysis. S. ALBAGLI. May 14, 1958 [May 14, 1957], No. 15571/58. In order to determine the velocity of submarines, the waveform of the echoes of ultrasonic pulses is analyzed to ascertain the Doppler frequency shifts. A single echo pulse incident at the receiver is used to generate a train of pulses, each of the same profile as the generating pulse beat of a mere fraction of its duration, and the required analysis is performed on this train. The initial echo pulse is first converted to an electrical signal, and the values of a selected series of ordinates are stored in memory devices. The latter are then electrically scanned, at a speed which is a multiple of the initial recording speed, to produce a train of pulses having the profile of the generating pulse. The latter is then analyzed, to obtain the frequency shift due to target speed. The analysis is effected by feeding a selected band of frequency components from the train into a band-pass filter together with the output of a swept-frequency oscillator. The output from the filter, after rectification, is applied to a CRT together with the oscillator sawtooth control voltage so that the CRT displays at equal intervals the amplitude of the spectral components.
