Title: Biological treatment
IPC: C12N15/09
Filed: 1974-08-08
Abstract: A cell culture which produces a desired polypeptide is prepared by genetic modification of microorganisms. The process comprises the following steps:   a) splitting up molecules of a DNA receptor material obtained from a plasmid which is suitable for the infection of cells of the said microorganism, by treatment of the plasmid DNA with an endonuclease. b) Splitting up another genetic material which contains DNA donors and codes for the synthesis of a desired polypeptide, using a similar endonuclease, resulting in DNA fragments whose ends are compatible with those obtained according to a), c) mixing the DNA fragments obtained from the various sources, resulting in a random attachment of the DNA fragments under the influence of a DNA ligase, which results in hybrid DNA molecules which contain the combined fragments from both DNA sources, d) infecting the microorganism cells to be modified by contacting with the hybrid DNA molecules, e) allowing the infected microorganism to metabolise in the presence of a substrate which is suitable for conversion into the desired polypeptide and f) screening for production of the desired polypeptide and preparation of a cell culture which produces the polypeptide.   Preferred applications are the production of mammalian polypeptides and proteins, the production of bacteria by "foreign" enzymes and secondary metabolites, e.g. glucose isomerase, and the production of compounds such as citric acid and cephalosporin by modified tissue.

Title: Improvements in or relating to electroplating
IPC: C23F13/00
Filed: 1963-09-06
Abstract: In electroplating a shaped article of a relatively high hydrogen overvoltage metal having because of differences in geometry or accessibility one or more regions of non-plating relatively low current density, etching is prevented in the low current density regions by coating them or placing them in intimate electrical contact with a relatively low hydrogen overvoltage metal having an overvoltage of less than 0.33 volt at a current density of 0.1 amp/dm2 as defined in (The Corrosion Handbook by H. Uhlig, John Wiley 1948). The low hydrogen overvoltage metal may be applied to the low current density areas (a) from an aqueous solution containing the metal in ionic form by spraying, brushing, contacting, dipping, wicking, electroless or electrolytic plating, or by applying a paste containing such a solution or (b) from an organic solvent solution of compounds of the metal or a foramions sheet of or coated with such a metal may be pressed against the low current density areas. Specified low hydrogen overvoltage metals are platinum, palladium, rhodium, iridium, gold, black nickel and electroless nickel and the process is described as applied to electroplating ferrous articles with chromium or nickel.  In a specific example the inside of a steel pipe after vapour degreasing, anodic cleaning in alkali and acid dip brushed over with an aqueous solution containing 4 g/1 palladium chloride and 20 g/1 sodium chloride and acidified to pH 1.5 with hydrochloric acid.  The pipe was then anodically cleaned in a 200 g/1 chromic acid bath at a current density of 14.4 amps/dm2 of external surface and was then cathodically plated in an aqueous chromic acid bath at approx. 58 DEG C. containing sulphuric acid and potassium silicofluoride using lead alloy anodes containing 4% tin with a cathode current density of 49 amps/dm2.  The inside of the pipe was neither plated nor etched.  Examples of other low hydrogen overvoltage metal solutions are aqueous solutions containing 2.5 g/1 chloroplatinic acid or 4 g/1 hydrated chloroauric acid.  Pastes are also described comprising 1 to 2 g/1 rhodium chloride or 2.5 to 4 g/1 chloroiridic acid thickened with silica gel, methyl cellulose, polyvinyl alcohol, gelatine, or agar-agar.

Filed: 1936-12-29
Abstract: 488,031. Valve generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd., and WILKINSON, K. J. R. Dec. 29, 1936, No. 35633. [Class 40 (v)] The initial portion of the flux generated by the discharge of a condenser through an inductance is used for supplying a magnetic scanning field to a cathode-ray tube, the discharge being initiated by controlling the grid potential of a gas-filled valve having three or more electrodes. As shown the condenser C is charged over resistance R and is periodically discharged through the scanning coil B of the cathode-ray tube A when the gasfilled valve T is made conducting by the supply of impulses over condenser E to the grid, the grid being normally negatively biassed to render the valve nonconductive. The invention may be used in connection with recurrent surge analyzers, as described in Specification 465,127, [Group XXXVI], or in television systems. Reference has been directed by the Comptroller to Specifications 400,976 and 472,293.

Abstract: 818,505. Discharge lamps. GERMESHAUSEN, K. J. Nov. 22, 1956, No. 35718/56. Class 39(1). In a gaseous discharge device, particularly for use in flash illumination, a cup shaped screen, formed a least in part of mesh-like construction, is dispose( about the cathode with th opening toward the anod for trapping particles sput tered off the cathode during a discharge. As shown in Fig. 1 the mesh-like portio: of the trapping means 5, which may be of insulatin or conducting material, i in contact with the envelop at its open end and is secured to an insulating disc 9 at its lower end. Any sputtered particles which are not trapped by the mesh upon the expansion of the gas due to the initiation of a discharge pass through the mesh but are trapped by it on the subsequent return of the gas into the region between anode and cathode so that no particles are deposited upon the walls of the tube between the anode and cathode. If the discharge through the tube is oscillatory, trapping means may be disposed about both main electrodes. Trapping means for use with a cylindrical cathode may comprise an insulating sleeve surrounding the cathode and extending almost to the walls of the tube and a planar mesh stretched over the end of the sleeve remote from the anode. In a further embodiment the trapping means comprises an insulating cylinder 9, Fig. 4, a cylindrical mesh 5 and a metal disc 15 supported by the cathode lead 1. In this device substantially all the sputtered particles are trapped by the disc 15 upon the expansion of the gas. The cathode may be a cold cathode of a substance such as tungsten, molybdenum or tantalum, uniformly sintered and bound together into a unitary mass with an oxygen-containing compound of barium, strontium, calcium or the like and upon which a relatively small cold-cathode spot is formed. The discharge may be started with the aid of an external trigger electrode 13, Fig. 1.
