Abstract: 1321685 Preparing α-aminobenzylpenicillin KYOWA HAKKO KOGYO CO Ltd 12 Oct 1970 [16 Oct 1969] 48347/70 Heading C2A α-Aminobenzylpenicillin is prepared by reacting 6-aminopenicillanic acid with α-aminophenylacetic acid or an N-acylating derivative thereof in the presence of an enzyme from a micro-organism of the genus Pseudomonas, which enzyme will perform the said reaction but will not form penicillin G from 6-aminopenicillanic acid and phenylacetic acid. The enzyme is preferably produced by Pseudomonas melanogenum or Pseudomonas ovalis, and may be in the form of a whole or cell-free fermentation medium therefrom, a cell suspension, e.g. in phosphate buffer, or a purified enzyme preparation from the disrupted cells. The cells are cultivated in a conventional nutrient medium, separated if required, and the reaction is effected at pH3-8 and 25-50 C. The substrate may be an impure 6-aminopenicillanic acid preparation containing phenylacetic acid as an impurity, having been obtained by hydrolysing penicillin G. The α- aminophenylacetic acid may be in the form of an amide or ester, or an acid addition or base addition salt. The α-aminobenzyl-penicillin may be isolated from the reaction medium by extracting with water-immiscible solvent, absorption on ion-exchange resin or charcoal, by iso-electric point precipitation and/or precipitation by a water-miscible non-solvent. Purified solutions of the product may be lyophilized.

Each passage 38, 39 contains a check-valve 42, 46 which when its associated passage is connected to the exhaust end of the motor is by-passed and remains closed. In a modification, the flow control valve 54 Fig. 4 throttles the exhaust from one end only of the motor, e.g., a double acting lift cylinder 60. In operation, and with distributing valve 61 moved to the right of its neutral position shown, pump pressure is directed through a line 73, a lateral part 77 of valve 64 and an orifice 83 Fig. 5 to a chamber 82 where it acts against the end of the valve spool 67 and moves it to the right against a spring 70 a sufficient distance for lands 86, 87 to uncover portions 79, 80 of service passages 71, 72 connected to the upper and lower ends of cylinder 60 thereby lowering the load. In the event of fast descent resulting in near cavitation the pressure drop in chamber 82 results in partial return of spool 67 to a position in which exhaust from the cylinder bottom is restricted by notches 90 in land 87 and at the same time pump delivery is restricted by notches 89 in land 86. To lift the load, valve 61 is moved to the left and pump pressure in a line 74 by-passes valve 64 and opens a check-valve 93 to gain access to the lower end of cylinder 60, the upper end of which is connected through a check-valve 95 to the valve 61.

Title: Improvements in photographic media and process for producing same
IPC: G03C1/496
Filed: 1963-12-11
Abstract: A photographic medium comprising a sensitized binder free layer of silver halide on a substrate is formed by vapour depositing the silver halide in the presence of a substance, other than silver, which reacts with the silver halide to form a sensitizer distributed through the silver halide. The silver halide layer is 0.1 to 0.5 microns thick and the reactable substance to form the sensitizer may be Fe, In, Te, Sn Pb and their salts such as the bromides.  The substrate may be glass, paper, gelatine, polyethylene terephthalate, polyvinyl chloride, copolymers of vinyl acetate and vinyl chlorides, polystyrene, polyamides, cellulose acetate and cellulose propionate. The substrate may also first be coated with a subbing layer.  The sensitizer may be incorporated in the silver halide according to any of the following processes.  (1) The silver halide and reactable substance are vapourized separately, and the vapours allowed to mix. (2) The silver halide and reactable substance are mixed together and vapourized together.  (3) The halide vapour is allowed to pass over and contact the reactable substance placed between the halide source and the substrate.  (4) The reactable substance is placed in contact with the molten silver halide.  The use of Pb as the reactable substance produces a Pb halide sensitizer which provides a photographic medium which yields a strong print-out effect when briefly exposed to actinic radiation.

Filed: 1966-11-07
Abstract: 1,200,455. Doffing winding machines. ERNEST SCRAGG & SONS Ltd. 1 Nov., 1967 [7 Nov., 1966], No. 49832/66. Heading D1J. The doffing operation is carried out without stopping the yarn feed to the winding position. A spool 15 is rotatably and releasably mounted in a support 40a in contact with rotating roll 14 so that when the support is adjusted to release the full spool, the spool moves away from the traversing yarn guide 16 over an angle plate 24 and into contact with an auxiliary roll drive 18 which continues to rotate the full spool. The support 40a then swings upwardly to receive an empty spool from magazine 45 and returns to the winding position in contact with roll 14. The yarn which has continued to wind onto the full bobbin is then severed at a point between the full and empty spools and the yarn immediately picks up on the empty spool, possibly assisted by an air blower. The auxiliary roll drive is effected at each winding on position by a pair of rollers 18 capable of serving the winding positions, one at each side of the machine, and having a reversible drive. The rollers 18 are seperable to allow a full spool to fall onto a conveyor 19 for removal from the machine. The severing device 25 is disposed beneath a slot 32 in the plate 24. The yarn in passing over the plate 24 to the displaced spool 33 enters 32 ready for severing by rocking of one of the pin of blades 26 of the device 25. The spool support comprises a pair of arms 40, 41 mounted on a shaft 42 which is rotatable into a position in which pads 43 on the arms can grip an empty spool lodged between spring lips 44 at the mouth of magazine 45. The arms 40, 41 may be axially seperable to release a full spool and spring loaded together to normally grip a spool. Alternatively one of the arms is rigid while the other has a pivoted forearm for effecting gripping and release of the spool. The arms swing relatively to the shaft during winding and are swung by the shaft between the winding and pick up position, due to an arm 81 rigidly connected to the shaft having an arcuate slot in its end and a bar 83 extending therethrough and being secured to brackets 40c, 41c on the arms. The yarn being wound has passed from a creel 10 through a false twister 12 to the winding position.
