Title: Process for the production of optically-active ª -alkyl-substituted phenoxyacetic acids and the alkylamides thereof
IPC: C12P7/40
Filed: 1962-09-13
Abstract: The invention comprises the alkylamides of optically active a -alkyl substituted phenoxyacetic acids, specifically L(-) -a - phenoxybutyryl isobutylamide and a process for the production of the optical isomers of said acids by converting the racemic acid to its racemic alkylamide, subjecting the latter in an aqueous medium to the action of a fungus of the genus Fusarium to effect complete hydrolysis of one of the isomeric alkylamides in the racemate and separating and recovering the enantiometic a -alkyl substituted phenoxyacetic acid thus produced. The hitherto unhydrolysed amide may then be hydrolysed for recovery of the enantiomeric acid, e.g. L-a -phenoxybutyric acid; the latter may be converted to its acid chloride with SOCl2.

Title: Improvements in or relating to the manufacture of artificial fibres
IPC: D01G1/02
Filed: 1927-12-24
Abstract: 308,645. Ferrand, F. Dec. 24, 1927. Apparatus for making filaments. - Artificial staple fibres are made directly by subdividing at regular intervals the column of solution with which the extrusion nozzles are fed. This can be carried out by the intermittent injection of a suitable fluid, which is preferably liquid but may be gaseous, into the column of solution. In the apparatus shown, cellulose solution passes from pipe 30 through pump 25, filter 24, pipe 23 and passage 22 to the annular passage 21 and cavity 20. Thence, it passes along passage 18 and pipe 18a to the spinning nozzle 19 in the coagulant bath 26. The diaphragm pump 6 actuated by cam 8 bearing on tappet 7 draws water from pipe 10 through a non-return valve and passage 12 into chamber 9 and expels the water through passage 13 and non-return valve 14 into passage 15 whence the water issues into cavity 20 and subdivides the column of cellulose solution entering passage 18, so that the solution is coagulated in the form of staple fibres. The fibres issuing from the several minute orifices 19<b> of the spinneret 19 are collected on coagulation by the funnel shaped mouth 27 of the syphon pipe 28, along which they are conveyed together with coagulating solution into the conduit 29, in which they are treated to remove excess of coagulating liquid.

Abstract: 837,649. Axial-flow compressors. GENERAL ELECTRIC CO. Nov. 12, 1957, No. 35218/57. Class 110 (1). [Also in Group XXV] In an axial-flow compressor having radiallydirected stator blades mounted on a casing for rotation about their axes by means of actuating rings encircling the casing and connected by levers to the bases of the blades, the rings are connected to the levers by universal joints, and the levers are secured to the bases of the blades, relative rotation between the levers and their blades being prevented by tangs on the bases received within openings in the levers. In a multi-stage axial-flow compressor forming part of a jet-propulsion engine, each stator blade 30 is pivoted in a bore 24 and a counterbore 26, both of which are lined with a bearing material such as polytetrafluorethylene. The recessed end of a lever 42 is attached to the blade by means of a stud 36 and tangs 40, each integral with the blade, and also holds a retaining ring 38 against the end of the blade stem. The levers 42 of each row of blades 30 are connected to a ring 60 by ball joints 76. Each ball joint is attached to the ring 60 by a pin 64 which is retained by a cotter pin 72 and a clip 70 which goes over an enlarged part 66 of the pin. Each ring 60 carries a pin which engages a corresponding cam slot in a longitudinally slidable arm, so that when the arm is moved by an actuator in accordance with a change in speed, temperature or pressure, the rings 60 are rotated in unison to adjust the pitch of the stator blades.

Abstract: 306,660. Cunningham, J., and Ruston & Hornsby, Ltd. Dec. 31, 1927. Hollow - ware. - The closure c of a cylindrical metal chamber for resisting high interna.l fluid pressure, such as an air receiver, bottle for storing liquids or gases under pressure, or a drum or header of a steam generator, is formed from a separate piece joggled at d and placed inside the end of the chamber b, which is then shaped at g to correspond with the shape of the end piece to form an overlapping surface contact joint, the joint being finally welded or otherwise sealed at j so as tc form a continuous exterior surface. Short screws may be passed through the joint, preferably towards the inner circumferential edge of the end piece, and welded or otherwise sealed in position. The neck of the closure may be formed with a flange f for coupling the chamber to the source of air pressure or place of delivery or may be internally screw-threaded. The contacting surfaces of the joint may be machined.

Abstract: 761,573. Squirrel-cage constructions. TURNER, Ltd., E. R. & F. Dec. 21, 1954 [Dec. 21, 1953], No. 35545/53. Class 35. A squirrel - cage is formed of laminations arranged parallel to the rotor axis and held in place by end rings and by a preformed or welded retaining ring placed axially midway of the rotor. The cage winding comprises strips of copper, alternating with the laminations 1, and of end rings 3 which fit into notches provided in the copper strips and laminations. The Specification describes various arrangements of the central retaining ring, but in all the arrangements this ring does not project beyond the rotor surface. In Fig. 1 the ring consists of a circumferential weld 7 in a notch 6 formed near the periphery of the assembly. This weld 7 may be on the inside edge. Also instead of a weld there may be a metal ring. In Fig. 5 the retaining ring is formed upon the lamination supporting core 2 by making the latter with two different outer diameters and having a notch at its centre with a sloped shoulder 12 to fit into corresponding inner parts of the assembly. Fig. 6 shows the laminations 1 and the winding strips made in two parts 14, 15 joined electrically and mechanically by a ring 16 which fits into notches, whereas in Fig. 7 (not shown) the two parts are joined by two L-shaped rings similar to the end rings 3.

[Also in Group XIII] Plastic material, e.g., ice-cream, is shaped into blocks in freezing cells revolving at a constant level in a rotary freezing machine into which it is fed in a frozen state from a filling machine having a container 31 and at least one row of outlet tubes 34 which are moved down towards the bases of the cells and are then moved upwards as the plastic material is discharged, to avoid the formation of air pockets in the cells, the container and outlet tubes being carried by a vertically movable member, e.g., a tube 4, connected to a rod 7 carrying a roller 8 engaged by a cam 9. On rotating the cam 9 from the position shown the container 31 moves downwardly and each tube 34 passes into a freezing cell 41 to be telescoped into a tube 33. On the downward movement a drum 14, having cylindrical transverse bores 25 containing free pistons 26, is withdrawn clear of the lower ends of rods 27, and the bores 25 above the pistons 26 are filled with ice-cream. A cam 24 now operates a toothed rack 22 to rotate a gear wheel 20 which, through a pawl 19 and ratchet wheel 18, turns the drum 14 through 180 degrees. The cam 9 now raises the container 31 so that the pistons 26, now above the ice-cream in the bores 25, contact the rods 27 and the combined weight of the pistons 26 and rods 27 force the ice-cream from the bores 25 into the cells 41.

[Class 135] [Also in Group XXXV] The viscosity of fluids such as solutions, emulsions, and suspensions, e.g. paper-making stock, is automatically regulated by a constant speed impelling device forcing the liquid through a convergent nozzle, a relay, which may be of the leak-port type described in Specification 116,074, [Class 135], controlling a valved supply of make-up water in accordance with fluctuations in the power consumed by the means driving the impelling device. The fluctuations are amplified by the convergent nozzle. Paper stock is fed into a sampling tank 3, a discharge pipe 9 maintaining a constant fluid level, and a portion of the stock is driven by a marine screw 13 and electric motor 4 through a convergent nozzle 6, a swan neck tube 7 reducing the effective head of fluid, and baffles 11, 12 above and below the propeller converting any churning action into a forward thrust.
