Title: Improvements in and relating to aircraft control devices
IPC: G05D1/04
Filed: 1943-08-13
Abstract: 586,280. Fluid-pressure servomotorcontrol systems. JACK & HEINTZ, Inc. Aug. 13, 1943, No. 13168. Convention date, April 22,1942. [Class 135] In an automatic pilot comprising a gyroscope 83, Fig. 2, balanced oil valve 90, and servomotor 96 operating the elevators 2 for controlling pitching, and supplementary means controlled by a barometric device for maintaining flight at a predetermined altitude, the supplementary means includes a bellows 115 acting on a pivoted nozzle 103, the jet of pressure oil from which actuates a valve 113 also controlling the elevator servomotor 96. The gyroscope is air operated-and acts on a diaphragm 88 connected to the piston of the valve 90. Movement of the latter connects the two sides of the piston of the servomotor 96 to pressure and exhaust respectively. A follow-up mechanism is connected from the elevators back to the gyroscope. The nozzle 103 is pivoted on a tube 104, Fig. 3, by which pressure oil is led to the nozzle, the connection between the bellows 115 and the nozzle being through link 117 ... 119. As the nozzle pivots, the jet flows into one or other of passages 107 leading to the ends of the valve 113 to move the latter and so connect the sides of the piston of the servomotor 96 to pressure and exhaust respectively. To set the apparatus for flight at a particular altitude, the position of the nozzle is adjusted by rotating a shaft 128 which, through a worm and pinion, rotates a cam 132. The latter acts on a spring-loaded lever 123 connected by a link to link 117. The remainder of the apparatus included in the automatic pilot is similar to that described in Specification 586,279.

Title: Dense sodium carbonate process
IPC: C01D7/12
Filed: 1962-04-06
Abstract: <PICT:0962964/C1/1> Dense soda ash is prepared from a crude aqueous dispersion of NaHCO3 by heating said dispersion under superatmospheric pressure so that the transition temperature of monohydrated Na2CO3 to anhydrous Na2CO3 is below the temperature at which the dispersion is heated, and continuing the heating until a minimum of 55 mol. per cent of the NaHCO3 is decomposed, thereby forming crystals of anhydrous Na2CO3 in mother liquor, and separating the crystals of anhydrous Na2CO3 from the mother liquor at a temperature above said transition temperature of monohydrated Na2CO3 to anhydrous Na2CO3.  The reaction may be performed at 150-225 DEG C. and 80 p.s.i.a. to 500 p.s.i.a. in a single vessel or separate vessels.  In the Figure, crude NaHCO3 and recycled liquor are mixed in tank 14, and heated by passage through heat exchanger 22 by recycled mother liquor and then passed to decomposition vessel 30 and heated to 100-190 DEG  C. at up to 225 p.s.i.a. by water and carbon dioxide resulting from further decomposition in pressure vessel 32, to decompose a minimum of 20 mol. per cent of NaHCO3. The partially decomposed mixture is then passed to pressure vessel 32 via heat exchanger 36 and a minimum of 55 mol. per cent of NaHCO3 decomposed, from where it passes to crystal separator 24 operated at 150-225 DEG C. and 175-400 p.s.i.a., the anhydrous Na2CO3 withdrawn and dried.

Abstract: 1,255,198. Halogenated aryl phosphate diesters. DYNAMIT NOBEL A.G. 14 March, 1969 [16 March, 1968], No. 13647/69. Heading C2P. A halogenated aryl phosphate diester of the formula in which R<SP>1</SP> and R<SP>2</SP>, which may be the same or different, are halogenated phenyl radicals or together represent halogenated diphenyl alkane or halogenated diphenyl radicals are obtained by reacting, at 50 to 220 C., a halogenated phenol or halogenated bis-phenol with a phosphorus ester dichloride of the formula O= P(OR)C1 2  in which R is a methyl, ethyl or propyl group in the presence of a catalytic quantity of an organic compound of N, P, As, Sb or Bi which compound contains at least one bond from an organic radical to said element or in which the element is nitrogen which forms part of a heterocyclic ring, or of a salt of one of such organic compounds, with the proviso that when said organic compound is a tertiary amine, the HCl vapour pressure of the hydrochloride thereof is less than the reaction pressure. The reaction may be carried out in the melt in the presence of an inert solvent or solvent mixture, e.g. a hydrocarbon or an  ether, and is preferably carried out at normal pressure, although a pressure of up to 12 atmospheres may be used. The reactants are preferably used in equimolar amount or an excess of the halogenated phenols may be used. The halogenated phenols may be mono-, di- or polyhalogenated monohydric phenols optionally substituted by alkyl groups and in which the halogen is Cl, Br, F or I or halogenated bis phenols optionally substituted by alkyl groups, e.g. 2,2<SP>1</SP>-methylene (or -2,2<SP>1</SP>-propylene) - bis- (3,4,5-trichlorophenol. The catalysts may be tertiary amines containing aliphatic, cycloaliphatic or aromatic radicals or may be tertiary heterocyclic amines. Especially suitable are tertiary amines containing nitrile groups. Other suitable catalysts are phosphonium halide compounds, stibonium compounds, arsonium compounds, and various organic phosphines and stibines and the catalyst is generally used in an amount of 0À1 to 10 mole per cent based on the phosphorus ester dichloride used. The HCl gas formed in the reaction is advantageously flushed from the reaction system with an inert gas, e.g. nitrogen, and the by-product RCl is also eliminated during the reaction. The products have pesticidal properties and for this purpose may be formulated in admixture with solid or liquid carriers or diluents. They are also useful as additives for lacquers, as textile-impregnating agents and as flame-retardants for plastics.
