Patent GB-864134-A (GB)
Title: A process for the production of tyrothricin and/or vitamin b
IPC: C12P19/42
Filed: 1958-07-22
Abstract: Tyrothricin and/or Vitamin B12 are obtained in a process which comprises adding a water soluble cobalt salt to an aqueous nutrient medium which contains one or more protein-containing substances, adding an inoculating culture of Bacillus brevis to the resulting nutrient medium, and growing the B. brevis in the nutrient medium to form tyrothricin and/or Vitamin B12.  Cobalt salts which may be employed are CoSO4 7H2O, K2CO(SO4)2 6H2O, CO(NO3)2 6H2O, K4 [CO(CN)6], CO2(SO4)3 18H2O, KCO(SO4)2 12H2O, and K3[CO(NO2)6] with cobaltous chloride and potassium cobalt hexacyanide being preferred. Subsequently the nutrient medium is acidified and submitted to extraction with an organic solvent, e.g. methanol, to separate tyrothricin, and the remaining culture liquid is contacted with an adsorbent, e.g. fuller's earth, active carbon, or ion exchange resins, whereby the Vitamin B12 may be recovered.  Examples describe the preparation of tyrothricin and of Vitamin B12 employing surface culture and submerged culture methods and in which the source of nitrogen in the nutrient medium is provided by an autolysate of compressed yeast, corn steep liquor, soybean flour, casein hydrolysate, molasses slops and peanut press cake.  Various recovery procedures are described.  Specification 782,329 is referred to.

Abstract: 691,695. Endless conveyers. DURKOPPWERKE AKT.-GES. Sept. 28, 1950. [May 30, 1949 ; May 10, 1950 ; May 10, 1950] No. 23751/50. Class 78 (i). In a belt conveyer having a belt comprising longitudinal side walls and transverse walls arranged at spaced intervals to form compartments, the belt is formed by sections having bent up sides and which are open at both ends and are carried bv an endless chain or like articulated member so as to overlap each other in tegulated manner, and the transverse walls are detachable and replaceable at varying distances apart to allow of varying the sizes of the compartments. The conveyer consists of overlapping slats l, Fig. 4, having upturned sides m, Fig. 9, and mounted on successive links k of an endless chain formed by loosely coupling the ends of the links, which are provided with keyholes, by pins o. The ends of the pins o rest on a guide f on the return run of the conveyer, the upper conveying run being supported by side plates d provided with guards n for the side walls formed by the upturned edges m. Side plates d and guide f are mounted on a tubular frame structure e. The transverse walls r are inserted at any points along the conveyer between the side walls being held in place by clips s, Fig. 6, engaging the side walls. Walls r may carry on their front or rear faces spring clips for attaching small articles to them. The conveyer is driven by a recessed disc i, Fig. 8, the ends of pins o entering the recesses. Freely pivoted to disc i are pawls u<SP>2</SP> which gravitate into engagement with pins o as the latter travel around the sprocket, thus holding them in place as the enter the guide f, the edge of the guide f disengaging the pawl as the pins are received by the guide. For the remainder of their travel the pawls rest against stops u<SP>4</SP>. Disc i is driven bv a motor controlled by a manual switch and a switch w, Fig. 9, arranged in series. Switch w is actuatable by projections x<SP>1</SP> either fixed on selected slats or preferably provided on each transverse wall r and insertable either through a hole in the slat at the position shown or through a hole x near the opposite end of the slat bv reversing the transverse wall right to left. In the latter position the projections are inoperative. Thus a particular transverse wall can be made to stop at the switch w by having its projection x<SP>1</SP> in the position shown, contact with the switch causing the latter to open.

The fabric may then be subjected to heat or pressure and, if desired, to a treatment with a swelling agent, shrinking agent, crease-proofing agent or shrink-proofing agent.  In examples: (1) a finished transparent fabric is printed with a composition comprising titanium dioxide, triethyleneglycol dibutyrate and an aqueous dispersion of polyvinyl butyral, dried and heated, and (2) a muslin fabric is printed as in (1), dried, heated and then transparentized in the usual manner.  Other pigments specified are lamp black, metal powders, flock and mica powder.  The print may be light or sufficiently heavy to produce a raised pattern.

Class 39(1) [Also in Group XXIII] In a method of sealing a disc 1 of crystalline material to a glass wall so as to provide an hermetic closure of an aperture in the wall, such as in sealing a sapphire window to the glass envelope 2 of an electric discharge device forming an infra-red ray sensitive device, the disc is supported on a block 4 of refractory material which does not readily oxidize, with an annular washer 6 of a heat resistive material intervening between the disc and the block, the inner edge of the washer being slightly within the periphery of the disc and the outer edge of the washer projecting beyond the periphery thereof, the open end of a tube 7 of glass suitable for sealing to the disc and fitting closely round the disc is rested on the washer, and the glass tube and disc are heated indirectly by heating the block so as to soften the end of tube 7 and cause it to flow on to, and seal to, the edge of the disc. The disc 1 is pressed against washer 6 by means of a pointed rod 13 to prevent softened glass flowing between the disc and washer. The block 4 is an ironchromium-nickel alloy heated by flames 11 or by means of induced currents or in a modification the block 4 is of carbon. When the tube 7, disc 1, and block 4 have been allowed to cool slightly and the edge 9 of the glass tube has hardened but is still hot, the tube and disc with the washer 6 attached thereto are removed from the block and the washer. which is of silver, platinum, or copper, is stripped off and the seal reheated for smoothing and annealing. In a modification, the washer is left on the seal whilst the latter cools, the washer being then removed mechanically, a mica washer being suitable, or chemically, such as by dissolving away a silver washer with nitric acid.

Abstract: 1481890 Polyurethane foams having coated cell walls LINK ASSOCIATES (RPB) Ltd 14 May 1976 [4 June 1975] 24182/75 Heading B2E An open-celled polyurethane foam is treated with a plastisol including polyvinylchloride mixed with a perfume, so that the walls of the cells of the foam become coated with the plastisol, and then heated to a temperature sufficient to cure the plastisol but lower than that at which the cellular structure of the foam would be impaired. The coating may be performed by soaking the foam in the plastisol and removing excessive plastisol before curing, such as by passing the foam through a pair of rollers or by wiping with a doctor blade. Alternatively, the plastisol may be applied by pouring. Optionally, after the impregnation with the plastisol an impervious outer layer extending over at least part of the outer surface of the foam may be applied. This may be of impervious polyurethane.
