Title: Improvements relating to copying
Inventor: GAMES ABRAM
IPC: B41L1/00
Filed: 1961-02-01
Abstract: 998,951. Copying documents. IMAGIC PROCESS Ltd. Jan. 26, 1962 [Feb. 1, 1961], No. 3811/61. Heading B6C. [Also in Division G2] A copy of an original 1 is produced by applying a film of vaporizing agent to the surface of the original 1 by means of a roller 3 which moves in relation to the original simultaneously with the paying-out of a strip 5 of unsensitized copy material into contact with the original at a point just to the rear of the roller 3, subjecting the original to infra-red radiation from a lamp 4 through the copy material so that the vaporizing agent is caused to distil on to the copy material 5 over areas representative of the original 1 to be copied to produce a latent image, and developing the image by transferring powdered ink 66 to the areas of the copy material 5 bearing the condensed vaporizing agent. The copy strip 5 is fed from a reel 21 around a roller 31, beneath the lamp 4 in contact with the original 1, around a roller 50 which guides it to rollers 51, 52 where it is inked, and the strip is finally guided by rollers 53 through a gap 54 in the housing 55 of the apparatus. Between the roller 52 and the rollers 53 the inked image passes a duct 70 attached to the reflector 71 of the lamp 4 and the heat from the duct causes the inked image to be fixed. A fan 13 is provided to assist the condensation of the vaporizing agent. A porous roller 60 is packed with an absorbent material impregnated with the vaporizing agent and co-operates with the roller 3 together with a doctor roller 12. An endless ridged conveyer 63 constitutes the bottom of a reservoir 65 for the powdered ink 66. The bottom edge 68 of the left-hand wall of the reservoir is flexible and a pool 67 of ink is built up in the vicinity of the roller 52. The ridges vibrate the edge 68 and keep the pool 67 agitated. In the embodiment of Fig. 1 (not shown), a roller forms the base of the reservoir and directly contacts the copy strip when it has been inverted. In the embodiment of Fig. 4 (not shown), the conveyer is replaced by a belt, which runs around two rollers, and a doctor wire, and in Fig. 5 (not shown), two rubber covered rollers set in a wall of the reservoir directly contact the copy strip 5. In the embodiment of Fig. 1 (not shown), the image is developed by running the apparatus over the inverted copy strip with the lamp off, and this step is then repeated to fix the image with the lamp on. The original may be mounted on an endless conveyer or on a roller, Figs. 6 and 7 (not shown), and the lamp may be mounted within a cylinder of heat-proof transparent material, Fig. 2 (not shown). There is an implication in the Specification that the image on the copy material may be directly visible. Specification 943,401 is referred to.

Title: Improvements in or relating to the isolation of the antibiotic neomycin
Inventor: ALLEN WILLIAM CHARLES
IPC: C07H15/232
Filed: 1955-02-16
Abstract: The invention relates to a salt of neomycin with a di-alkyl ester of sulpho-succinic acid and the use of this salt in the isolation of neomycin from aqueous solution including fermentation broths especially clarified broths.  The dialkyl ester of sulpho-succinic acid, preferably in the form of a water-soluble salt, especially the alkali metal salt, is added to the aqueous solution at pH 6.6 to 7.7 and in proportions of 1.5 to 2.0 parts ester per part of neomycin. The preferred ester is the dioctyl ester of sulphosuccinic acid in the form of its sodium salt.  The precipitated neomycin salt of the ester is removed from the reaction medium by adding adsorbent, e.g. kieselguhr, filtering, suspending the adsorbent matt in a water-miscible alcohol such as methanol or ethanol, filtering, and decomposing the neomycin ester salt by adding to the alcohol solution thereof (a) an acid, especially a mineral acid, or (b) a strong base, e.g. sodium hydroxide.  In the case of (a) using e.g. sulphuric acid, the oily neomycin sulphate is treated with adsorbent, filtered, washed with alcohol, slurried with water, filtered, treated with carbon and freeze dried or evaporated to dryness.  In the case of (b) the neomycin is precipitated from the alcohol solution to which sodium hydroxide has been added, by the addition of a non-solvent such as acetone.  On the large scale, adsorbent is added to the clarified broth adjusted to pH 6.6 to 7.7, and then the dialkyl ester of sulphosuccinic acid.  After filtration the solids are suspended in aqueous alcohol, the desired mineral acid added and the filtrate employed for the recovery of the neomycin salt of the mineral acid.
