Abstract: 1,096,270. Automatic control systems. GENERAL ELECTRIC CO. Dec. 31, 1965 [Jan. 21, 1965], No.55325/65. Heading G3R. A supply circuit for a monopole mass analyzer produces an alternating voltage having a unidirectional component, and means are provided for maintaining constant the ratio between the amplitude of the unidirectional component and the peak amplitude of the alternating voltage when the latter is varied, e. g. by sweeping, during the operation of the analyzer. The circuit includes a crystal controlled oscillator 12 generating a radio frequency signal which is applied to an amplifier 13; a resonant circuit 11 which receives the output from the amplifier 13 and which produces therefrom an alternating voltage with an added unidirectional component for application to the analyzer 4; and a servo circuit 14 which compares a sampled portion of the unidirectional voltage with a varying reference signal derived from a sweep generator 15 to produce an error signal which is applied over an amplifier 16 to the amplifier 13 whereby the input to the latter from oscillator 12 is modulated in amplitude thereby to control the magnitude of the unidirectional and alternating voltages supplied to the analyzer while maintaining the same proportional relationship therebetween. Suitable arrangements for the circuits 11 to 16 are described with reference to Figs. 3 and 4 (not shown).

Title: Treatment of permeable refractory or metal materials
IPC: C23C16/34
Filed: 1972-12-04
Abstract: 1432559 Permeable refractory materials and metals ADVANCED MATERIALS ENG Ltd 2 Oct 1973 [4 Dec 1972] 55910/72 Heading C1A A permeable refractory material or metal is treated by diffusing at least two fluids into the permeable material so that neither fluid meets any other except within the material and causing a chemical reaction between at least two of the fluids within the material to produce a deposit of refractory material within the permeable material, which latter may be a shaped, partly shaped, or unshaped body. "Permeable" is defined as meaning having accessible porosity, so that fluids have access to the interior of the material. The material must therefore be cellular; fibrous; sintered; made by reaction-bonding; or otherwise by agglomerating or rendering coherent otherwise loose material; or be of other form having accessible porosity. Thus the permeable material may be in the form of a tube, a reactant fluid being fed into the material from the outside and another reactant fluid being fed into the material from the inside of the tube. A sheet-like material or material in the form of a body having two sets of passages, e.g. a heat exchanger matrix, may be treated in like manner. Preferred permeable materials include silicon nitride, silicon carbide, and oxides of aluminium and of other elements which are ceramic materials. The deposit may be chemically the same as the permeable material treated, or may be different. In a preferred method, the deposit is silicon nitride and the two fluids are selected from ammonia, silicon tetrachloride, silane, silicon tetrafluoride, hydrazine, and nitrogen, especially silicon tetrachloride and ammonia, the ammonia being mixed with a third fluid, hydrogen. Alternatively, where the deposit is silicon nitride the two fluids may be silicon tetrachloride and nitrogen, the nitrogen being mixed with hydrogen. In general, a diluent fluid may be mixed with one or both of the reactant fluids. Silicon nitride material may be so treated to leave a deposit of silicon nitride therein.
