Abstract: 842,971. Controlling jet-propelled aircraft. UNITED AIRCRAFT CORPORATION. Aug. 12, 1955, No. 23355/55. Class 4. A supersonic propulsion nozzle for a vehicle comprises means for selectively conducting fluid under pressure to peripherally spaced openings, thereby creating shock waves in the nozzle to control the direction of movement of the vehicle. The shock waves are produced in the divergent portion of the exhaust nozzle 16 by admitting high pressure air from a diffuser section 12 of a ramjet unit through one or more selected conduits 34, Fig. 1. Where cooling air under pressure surrounds the nozzle, selected openings therein allow this cooling air to produce the shock waves. A separate gas reservoir 98 is necessary for rocket-propulsion units, Fig. 6. To provide an axial spread of the gas producing the shock wave, the nozzle may have groups of orifices behind which the gas is admitted under pressure, Fig. 7.

Abstract: 598,811. Vibration-dampers. STONE, L. J. Sept. 11, 1945, No. 23419. [Class 108 (iii)] The diameters of the rollers 23, 24 and associated circular tracks 22, 21 of a vibration-damper of the kind employing a non-parallel bifilar suspension of the roller type are determined from a prescribed formula, which, for small amplitudes of oscillation, is stated to ensure that the vibration of the damper is accommodated without slipping occuring between the contacting surfaces of the rollers and the tracks. The oscillating piece 20 is arranged with its depending limbs disposed on opposite sides of the carrier 19 and provided with two circular tracks 21, each of which is engaged by a roller 24. The intermediate portions of these rollers are of different diameters from the end portions 24 and constitute the rollers 23 engaging the circular tracks 22 in the carrier 19. Assuming that the two circular tracks 21 are spaced apart by a distance 2a, and the corresponding tracks 22 in the carrier are spaced apart to the extent necessary to give the necessary inclination of the suspension indicated by the angle a, the formular from which the diameters of the rollers and tracks are determined is I - d1 d4/d2 d3 =L sin a/a ,where d1 and d2 are the diameter of the tracks 22, 21, d3 and d4 are the diameters of the corresponding rollers 23, 24, and L=¢ (d1+d2-d3-d4) where, instead of the links converging downwardly, the spacing of the tracks is such as to produce a system in which the links converge upwardly at an angle #, the formula is d1 d4 /d2 d3 I = L sin #/a If desired, the roller tracks 21, 22 may be identical, or the rollers may be of the same diameter throughout.

Abstract: 1,002,386. Knitting-machines. R. STOVASE. June 10, 1964 [June 19,1963], No. 24000/64. Heading D1C. A parallel bed machine has a transfer bar 8 associated with it to enable the rib fabric produced on the machine to be taken by the transfer bar and subsequently transferred to the needles of a full fashioning machine. The rib fabric is commenced by knitting the initial course on the needles of one bed 2 of the machine and simultaneously causing the yarn to be engaged by the hooks 29 of a drawing down bar 22 initially raised to enable the hooks to receive the yarn. After completion of the initial courses the needles of both beds are rendered operative and rib fabric is produced which is drawn down by the bar 22. When sufficient rib fabric has been produced the loops on the needles of the bed 1 are transferred to corresponding needles in the opposite bed 2. The needles of this bed are then advanced to extend the loops on them and simultaneously the hooks 28 of a transfer bar 8 are raised to penetrate the loops. The needles having withdrawn, the transfer bar is lowered having now received the rib fabric portion. The hooks 29 in the meantime are raised, whilst the fabric is clamped between a strip 33 and a pivoted member 34 so that the initial course loops pass beneath the hooks 29 which are thereupon pressed by a bar 40 so that as the hooks 29 are lowered they are cleared and become detached from the fabric. The transfer bar 8 may receive several portions of rib fabric and when required the bar is removed from the parallel bed machine.

Title: Improvements in or relating to the separation of aromatic amines
Filed: 1955-08-19
Abstract: A mixture of aromatic amines is treated with an aqueous agent capable of converting the amines into salts, or a mixture of salts of different aromatic amines is treated with an aqueous agent capable of converting the amine salts into free bases; in either case the agent is added in such amount that the product consists of a mixture of free bases in an organic phase and a mixture of salts in an aqueous phase, and these phases are separated and treated to recover a desired amine or amines which predominates in one of the layers.  The starting material may itself be a mixture of amines and salts, and a similar mixture may be used as the agent, in which case double decomposition occurs. Alternatively the agent is (1) an acid such as sulphuric, hydrochloric or acetic, or an acid-reacting substance such as sulphur dioxide or an acidic salt (e.g. an amine salt); or (2) an alkali hydroxide or carbonate or an amino compound.  The separated amine can be purified by standard methods, e.g. fractional solidification or distillation, steam distillation, molecular distillation, selective conversion into salts and recrystallization of the free bases or salts.  The process can be applied to mixtures of isomeric amines or of non-isomeric amines or of both.  The amines can be N-substituted provided they are still capable of forming salts.  Examples show the separation of mixtures of (1) o- and p-anisidines, (2) o-, m- and p-toluidines, (3) o- and p-chloroanilines, (4) o-chloroaniline and p-anisidine, (5) aniline and dimethylaniline, and (6) a - and b -naphthylamines.  Other mixtures that can be separated are those of o- and p-phenylenediamines.
