Title: Process for Producing Non-N-Alkylated Pyrrolidines and Substituted Pyrrolidines
IPC: C12N1/38
Filed: 1966-09-20
Abstract: 1,160,527. Antibiotics. UPJOHN CO. 20 Sept., 1966 [18 Oct., 1965], No. 41869/66. Headings C2A and C2C. The invention comprises a process for preparing non-N-alkylated pyrrolidines and non-N- alkylated substituted pyrrolidines which consists in the addition of a metabolic inhibitor to a micro-organism fermentation for the production of N-alkylated pyrrolidines and N-alkylated substituted pyrrolidines, the inhibitor being a water-soluble sulphonamide possessing antibacterial properties and a carbonyl reagent for inhibiting glutamic acid decarboxylase. The inhibitors may be sulphanilamide, sulphapyridine, thiocarbohydrazide, semicarbazide, thiosemicarbazide, furoic acid hydrazide, isonicotinic acid hydrazide and hydroxylamine. The inhibitor is preferably added after 24 hours fermentation, in stages, in quantities of less than 5 g./litre and in total of up to 8 g./litre. The process is used for the preparation of (a) lincomycin D (i.e. N-demethyl lincomycin) by cultivating the lincomycin-producing micro-organism Streptomyces lincolnensis var. lincolnensis NRRL 2936 of Specification 976,765; (b) N-demethylcelesticetin by cultivating Streptomyces caelestis NRRL 2418 of Specification 768,971. N-Demethyldesalicetin of Formula III: is produced by hydrolysis of N-demethylcelesticetin of Formula II: in aqueous ethanol at pH 12À2. Salts are formed with inorganic acids, e.g. phosphoric acid, and organic acids, e.g. lactic, maleic, fumaric, pamoic, cholic, palmitic, mucic, camphoric, glutaric, glycollic, phthalic and other acids.

Abstract: 1,185,508. Hoses. UNIROYAL Ltd. 6 Sept., 1968 [14 Sept., 1967], No. 41907/67. Heading F2P. A hose which is capable of floating when filled with water has a body which is reinforced by a helically extending member 11 of glass fibre, adjacent turns of the helix being separated by a helically extending elastomeric member 10, and the glass fibre and elastomeric members 11, 10 being substantially of the same width radially of the hose and lying within a common layer of the hose. As shown, a layer 4 of rubber is first applied to a mandrel and over the ribs 3 of a nipple 1 made of resin bonded glass fibre, followed by a rubber-impregnated textile material ply 5 and an even number of layers of rubber-coated glass fibre cord 6 with alternate layers wound in opposite directions. The nipple 1 is then bound into the hose by winding, under high tension, two glass fibre tapes 7, after which a further rubber layer and breaker ply 8 is applied before the hose is partly vulcanized. A further layer 9 of rubber is cemented on to the hose and then the elastomeric and glass fibre strips 10, 11 respectively are wound helically on to the layer 9. The glass fibre strips may be of glass fibre filaments cured in resin, and twisted to form an elongated bundle, or by a number of plies of tape, or cloth, woven or otherwise formed unidirectional glass rovings dipped in resin and set to the intermediate cure stage, or by bunching together unidirectional rovings in resin and passing them, through a hot die, to mould them to the required crosssectional shape. On top of this latter layer further layers of rubber, breaker ply, and a final outer covering of rubber, indicated together as 12, are applied before the hose is finally vulcanized.

[Also in Division B5] Formers 32 inserted in a folded web of material have portions 33 shaped to co-operate with external formers 34 so that re-entrant bottoms are formed on the bags produced by transversely welding the web between the formers 32. In the form illustrated the transverse welds are performed by rods 43 carried on endless chains. The rods 43 may also weld together opposite walls of triangular pockets 47<SP>1</SP> (Fig. 8) at the ends of the bottoms. The web may be of polyethylene or of polyethylenecoated paper. Conveying the empty bags.-The bags are transferred from the formers 32 to carriers 54 each providing a supporting surface adapted to fit the re-entrant bag bottom and each provided with grippers 62 operated by a cam surface to grip the fin seals of the bags. The carriages 54 are mounted on an endless chain and are raised and lowered by a fixed cam track 67 to bring them into and out of engagement with the bagcarrying formers 32 and with filling nozzles 100. The ends of formers 32 may be mounted for radial movement (Fig. 15, not shown) to facilitate transfer of the bags. Filling the bags.-The bags are carried in an arcuate path while they are filled from nozzles 100 carried by a rotary filling head 90. The nozzles 100 may initially seal against the bottom of the bag (Fig. 5, not shown) and may be gradually retracted as the bags are filled. Pressure and vacuum connections to the nozzles 100 may provide for filling by differential pressure action, and the nozzles may be fed with predetermined weights or volumes of material.  Re-shaping the filled bags.-The bags pass through suitably shaped cylinders 80 which can form them to the correct shape for sealing and expel air. Sealing the bags.-The bags are conveyed by endless bands 84 engaging on opposite sides of the mouth through fixed sealing bars 83. The bags may be supported during the subsequent sealing by the conveyer carriages 84 or these may be retracted before sealing begins.

Abstract: 1,198,463. Releasable fastenings. F. J. FUCHS. 20 Sept., 1967. No. 42783/67. Heading E2A. [Also in Division F1]  A device for discharging predetermined volumes of fluent material to separate but adjacent outlets in a nozzle block 16 comprises cylinders 12 for the material, each cylinder having a piston 40 which has a clutch device for unidirectional movement with a rod 42. The heads 44 of the rods 42 are engaged by leverlike cams 30 which are pivoted at 32 on a member 20 slidable on a plate 10 at right angles to the cylinders 12 against the action of a return spring 34 to the left as shown. The ends of the cams 30 are engaged (by flanges 33 on volume adjusting screws 22 having control knobs 24. The initial position of the heads 44 is adjusted by screws 78. Charging ports 104 adapted to receive the screwed ends of colour tubes are provided in the block 16 for charging each cylinder and returning the pistons 40 to the top of the rod 42. To produce a given colour from different colours stored in the cylinders 12 each knob 24 is set to a predetermined angular position which deflects the appropriate cam 30 so that when the member 20 is moved at right angles to the cylinder 12 predetermined relative quantities of material are discharged from the nozzles in block 6. The nozzles may incorporate non-return valves. The unidirectional device comprises discs 54, 56 (Fig. 4) frictionally engaging the rod 42 with a plurality of balls 59 disposed between them in a tapered recess 52 in the piston member 50. The disc 56 has pegs 57 which engage shoulder portions 66 on the piston seal member 60, the arrangement being such that rotation of the rod 42 in one direction allows the pegs 57 on downward axial movement of the rod 42 to drop from shoulders 68 into gaps between the shoulder portions 66 so that the balls 59 engage the rod 42 and the recess 52 to drive the piston. Axial movement in the opposite direction releases the balls and after subsequent rotation the pegs 57 re-engage the shoulder 68 so that the rod is free to move axially. The rods are rotated by the engagement of cams 86, 88 (Fig. 3) on the member 20 which engage projections 46 on the ends of the rods 42.

The spigot 4 has a threaded extremity 5 for entry into a threaded bore in the end of the handle part 1 and a cylindrical part 9 for supporting the cutting ring 10, the latter being clamped between the end of the handle 1 and a shoulder 6 on the spigot. A vice for assisting in the cutting off of the unwanted length of conduit, Fig. 5, comprises fixed and movable end plates 14, 17 connected by a lead screw 15, the movable plate being cut away to form a cradle-like support 18 which engages a groove 19 in a bush 20. The bush has a cylindrical boring 21 and is threaded on to the conduit 13 and pushed as far as it will go over the part of the conduit containing the ring or sleeve 12. The tool, conduit and associated bush are then inserted in the vice with the threaded extremity 2 of the tool engaging the end plate. The handle 16 is then turned to rotate the lead screw and draw the movable end plate 17 and its associated bush 20 towards the fixed plate 14 causing the bush to ride up that part of the conduit containing the ring or sleeve. Finally that part of the conduit surrounding the cutting ring 10 will be gripped between the cutting ring and bush causing the unwanted end 22 of the conduit to be cut cleanly along the cutting edge 11.
