Patent GB-797952-A (GB)
Title: Improvements in and relating to the manufacture of organic amides
IPC: C07C233/12
Filed: 1955-06-09
Abstract: Carboxylic acid amides are prepared by flowing a mixture of a carboxylic acid ester and a primary or secondary amine in a thin film through a heated reaction zone to form an amide and an alcohol or an amide and a phenol, said alcohol or phenol having a lower boiling point than said amine, amide and ester, maintaining the temperature of said zone above the boiling point of the alcohol or phenol but below that of the ester, amide or amine, and removing alcohol or phenol vapour from said zone, the reaction being at least substantially completed in said zone and the amide being separated, if necessary, from the reaction mixture after passing through said zone.  The process may be conducted continuously and under normal or reduced pressures.  The reaction may be effected by passing the mixture of reactants down a heated packed or unpacked column or down an inclined surface, the alcohol or phenol vapour being distilled countercurrently to the flowing mixture.  The carboxylic acid esters used are those which will form an alcohol or phenol having a distillation temperature below that of the ester and amine used and of the amide formed.  When one of the reactants is solid it may be dissolved in an excess of the liquid reactant, the amide formed being separated by cooling and filtration, and the excess liquid reactant recycled.  When one or both of the reactants are solid, the reactants may be dissolved in an inert solvent which may have a low boiling point and be removed from the reaction zone by distillation with the alcohol or phenol or which may have a high boiling point and be removed with the amide formed and any excess reactant.  In examples: (1) a mixture of aniline and ethyl benzoylacetate is continuously passed down a heated, packed column, ethanol distilling up the column and benzoylacetanilide being withdrawn from the bottom; (2) 2-(benzoylacetamido) - 5 - nitroanisole is similarly prepared from 2-methoxy-4-nitroaniline and ethyl benzoylacetate; (3) N - [g  - 21 : 41-di - tert. - amylphenoxy) - n - butyl] - 1 - hydroxy-2-naphthamide is prepared from phenyl 1 - hydroxy - 2 - naphthoate and g  - (2 : 4 - di-tert. - amylphenoxy) - butylamine, xylene being used as an inert solvent; (4) N-[41-(411-tert.-butylphenoxy) - phenyl] - 1 - hydroxy - 2 - napththamide is prepared from a solution of phenyl 1-hydroxy - 2 - naphthoate and 4 - tert. - butyl-41-amino diphenyl ether in xylene.

Title: Aircraft with jet fluid control ring
IPC: B64C39/00
Filed: 1962-05-04
Abstract: 965,490. Aircraft. HAWKER SIDDELEY CANADA Ltd. May 4, 1962 [May 8, 1961], No. 17188/62. Headings B7G, B7K and B7W. An aircraft has a gas displacement passage 30 which terminates in an annular nozzle 35, the inboard wall of which curves away therefrom in a smooth convex surface, and a gas control ring 38 movably arranged adjacent the outboard wall of nozzle 35 and shaped to direct gas around the convex surface, the position of the ring being controlled from the gas impeller rotor 24. The ring is supported by six links 39 passing through apertures 43 in wall 31 of passage 30, and is connected by links 48 and cables 51 to bell-crank levers 101 actuated by fluid-operated actuators 88, 90, 92, 94, 96, 98. Operation of pilots' control column 67 adjusts the pressure in jacks 59, 60, 61 which through rods apply a force to a shaft 58 on which rotor 24 rotates, such control is as disclosed in Specifications 914,597, 914,598. The lower end of shaft 58 is attached by a torsion bar to baseplate 25 and carries six tappets which, due to movement of shaft 58, move toward and away from nozzles through which high pressure air passes; changes produced in back pressure in chambers connected to these nozzles actuates actuators 88, 90, 92, 94, 96, 98 which adjusts the position of ring 38 accordingly. Narrowing a section of the nozzle 35 causes the issuing gas to pass further around the convex surface before breaking away and conversely; so the annular stream of propulsive gas is deflected to give a horizontal component of thrust, Fig. 11. The centre of the annular stream is " filled " in by air from annular nozzle 35a. As aircraft speed increases aerodynamic lift increases to raise the nose of the aircraft. Yaw controlled is obtained by blades 115 in passage 30 controlled from column 67 as in Specification 914,597. In Fig. 7, not shown, the impeller shaft base is held in a neutral position by springs and is connected to the bell-cranks 101 by rods. Automatic stabilization occurs if the aircraft acquires a rotational velocity about a turn axis lying normal to the spin axis of the rotor; the rotor will move relative to the aircraft body to operate ring 38 to stabilize the aircraft.

Title: Improvements in or relating to releasable fasteners
IPC: F16B21/07
Filed: 1943-10-20
Abstract: 573,227. Stud fastenings. ODDIE, F. A. Oct. 20, 1943, No. 17231. [Class 44] In a cowling or like fastener of the kind in which a pointed stud has flats engaged by the free ends of converging spring tongues D when the stud is-inserted therebetween, the stud is in two parts A, B arranged so that the effective length of the stud may be adjusted, after the stud has been engaged, to draw the fastened members E, F together tightly. The part A, having the usual head with screw-driver slot for operation, is externally threaded to engage a threaded bore in the part B so that length may be adjusted by relative rotation of the parts, removal of part A from part B being prevented by turning inwards the upper edge of the latter. Accidental relative rotation is prevented by a spring detent C housed in a transverse slot in part A and yieldingly engaging recesses in the inner wall of part B. Part B is provided with flats forming shoulders engaged by the ends of tongues D as shown and is so shaped that when it is rotated through 90‹ the tongue ends ride off the flats and co-operate with the part B to eject the stud. The stud is rotatably anchored in an aperture in the cowling or like member F by a resilient washer F<1> which also serves to make a fluid-tight joint between the parts E, F when these are drawn together. The stud is passed through an aperture in the support or other member E into engagement with the tongues which are carried by a base-plate permanently secured to part E. The tongues D hold part B more firmly than does the weaker detent spring so that after the stud has been engaged as in Fig 1, rotation of head member A causes the detent to ride out of the recesses in part B, allowing part A to be screwed into part B to draw members E, F together. Rotation of head A in opposite direction screws part A out of part B to the full extent allowed by the inturned upper edge of part B, after which part B rotates with part A to effect release and ejection of the stud. Fig. 5 shows modified spring tongues of general S-form.
