Title: Process for preparing photogravure printing plates
IPC: G03F7/06
Filed: 1964-04-30
Abstract: 1,070,795. Production of photogravure printing plates. GEVAERT PHOTO-PRODUCTEN N.V. April 30, 1964 [May 1, 1963], No. 18071/64. Headings G2C and G2M. A photogravure printing plate is produced by exposing to light a light-sensitive hydrophilic colloid layer containing a polymer miscible therewith which 1) is insoluble in an acid medium or 2) forms in an acid medium, an insoluble complex with the hydrophilic colloid, the said polymer having acid groups or their water-soluble salts or functional groups which form acid groups when dissolved in water, which colloid layer is either a) a dichromate-sensitized hydrophilic colloid layer hardenable under the action of light by the presence of dichromate or b) is a silver halide emulsion layer hardenable in the exposed areas by tanning development, applying the exposed and hardened said layer to a metal surface e. g. copper and etching the metal surface with an acidic etching agent e. g. FeCl3 after removing the unhardened areas. The dichromate layer is preferably 30Á thick and the silver halide emulsion layer 20Á thick. Specified polymers are poly (vinyl hydrogen maleate) copoly (styrene/maleic anhydride), the reaction product of gelatine and phthalic anhydride, water soluble ethyl cellulose hydrogen phthalates water soluble salts of ethyl cellulose sulphobenzoates and poly (styrene sulphonic acid) and its water-soluble salts. Specified hydrophilic colloids are fish glue, poly (vinyl alcohol), gelatine and other proteins. The colloid layer may contain a pigment e. g. ferric oxide. The colloid layer may be on a paper support or in the form of a stripping film.

Title: Improvements in or relating to novel penicillin salt and process for preparing the same
Inventor: MURPHY HUBERT WILLIAM
IPC: C07D499/26
Filed: 1955-06-24
Abstract: The invention relates to the 1-benzamido-1-phenyl-3- piperidinopropane salt of penicillin of formula <FORM:0771164/IV(b)/1> wherein HP represents the acidic form of penicillin.  It is prepared by bringing penicillin and 1 - benzamido - 1 - phenyl - 3 - piperidinopropane together in solution in a reaction solvent in which the 1-benzamido-1-phenyl-3-piperidino-propane salt of penicillin is relatively insoluble, with the penicillin and 1-benzamido-1-phenyl - 3 - piperidinopropane in solution in amounts to form substantially more of the 1-benzamido - 1 - phenyl - 3 - piperidinopropane salt of penicillin than will dissolve in the reaction solvent.  Specified solvents for the reaction between the acid and base forms of these substances are ether, chloroform, 1,2-dichloroethane, methylene dichloride, diethyl carbonate and alkyl esters, e.g. ethyl or amyl acetate.  A soluble salt of penicillin particularly the alkali metal salts, e.g. sodium or potassium salts, amine salts, e.g. ethylene diamine salt, or ammonium salt may be reacted with a soluble salt of the base, e.g. hydrochloride in an aqueous medium.  Any penicillin may be used, e.g. penicillin G, penicillin F, penicillin X, penicillin O and penicillin V.  The salt may be used in the recovery of penicillin from solutions thereof.  The salt is used medicinally (see Group VI) for inducing prolonged anesthesia with "depot" penicillin activity.  1 - benzamido - 1 - phenyl - 3-piperidino-propane is produced by reacting beta - piperidinopropiophenone hydrochloride with hydroxylamine hydrochloride in water in the presence of sodium bicarbonate to form the oxime, beta - piperidinopropiophenone oxime, which is then reduced by hydrogenation using a Raney nickel catalyst in a mixture of ethanol and liquid ammonia to form 1-phenyl-3-piperidino propylamine. 1-phenyl-3-piperidino-propylamine is then reacted with benzoyl chloride in a mixture of benzene and pyridine to form 1-benzamido-1-phenyl-3-piperidino propane.ALSO:A therapeutic preparation having anaesthetic and "depot" activity comprises the 1-benzamido - 1 - phenyl - 3 - piperidinopropane salt of penicillin of formula  <FORM:0771164/VI/1> (see Group IV(b)) and a carrier therefor.  A solution in 70 per cent aqueous polyethylene glycol 200 has a long lasting anaesthetic effect.  Injections are also prepared by suspending the finely divided salt in water, a vegetable oil or other parenterally acceptable media such as diethyl carbonate. Optional ingredients are (a) therapeutically effective substances, (b) suspending agents and (c) surface active agents.

Abstract: 793,874. Laminates. BAKELITE, Ltd. May 24, 1956 [June 24, 1955], No. 18387/55. Class 140. Metal components such as sheets, foils, tubes, wires, and blocks are secured to articles moulded from compositions based on a synthetic resin which may contain a filler, by a heat-hardenable melamine-formaldehyde resin in contact with the composition and a layer of another adhesive for the melamine-formaldehyde resin and the metal, the whole being consolidated by heat and pressure. Suitable base resins are thermoplastics such as polyvinyl acetate or thermosetting types such as phenol-formaldehyde or aminoformaldehyde resins. The filler may be natural, synthetic, or processed'natural material. Examples of fillers quoted include wood flour, sheets of paper, powdered china clay, sheets of woven nylon or glass filaments, felts of glass filaments or yarns, and short fibres of asbestos. The melamine-formaldehyde resin may be applied to the base, followed by the adhesive; or the adhesive may be applied to the metal, followed by the melamine-formaldehyde resin; or the melamine-formaldehyde resin may be applied to the base and the adhesive applied separately to the metal. Examples are given of (a) bonding copper to bases composed of phenolic resin-impregnated paper laminates, the adhesives used being polyvinyl butyral, mixtures of polyvinyl butyral with phenol-aldehyde resins, and copolymers of butadiene and acrylonitrile; (b) forming a printed circuit by printing a pattern of resistors on a copper foil, bonding the patterned side to a laminate as in (a), printing a circuit on the copper-faced laminate with a resist ink then removing the unprinted copper by means of an etching solution, and (c) bonding two sheets of aluminium foil to a laminate comprising woven glass webs bonded by a melamine resin, the aluminium foils being coated on one side with a polyvinyl butyral resin and then with a melamine-formaldehyde resin, assembled with the laminate interposed and heated under pressure.

IPC: D01D5/20
Filed: 1930-06-18
Abstract: <PICT:0352692/IV/1> <PICT:0352692/IV/2> <PICT:0352692/IV/3> <PICT:0352692/IV/4> Artificial filaments resembling natural wool are obtained by performing in substantially immediate sequence a process which produces nodules in a filament issuing from a spinneret and a process which waves or crimps the noduled filament after the initial coagulation.  The nodules or variations in the section of the thread are obtained by rapidly varying the supply or pressure of the cellulosic solution fed to the spinneret forming the thread.  As shown in Fig. 2, spinning solution passes from a pump 2 through a pulsation device 3 to the spinneret 4.  The thread 7 is coagulated in the bath 5 and passed round a drawing wheel 6. It then passes to a waving device 9, which comprises a milled wheel rotating tangentially with a rubber wheel, and is then received in a container 10.  It may then be submitted to washing, bleaching, and dyeing operations.  If desired, the milled wheel may be heated internally.  In Fig. 3 the pressure variation of the solution is obtained by a compressed air method.  Compressed air enters through the passage 11 and expands in chamber 12 by moving the piston 13.  The passage 11 is then opened to exhaust and the piston 13 is moved back by the pressure of air on the ledge 15. The movement is repeated rapidly.  In Fig. 4 the piston 13 is connected to a spring blade 16, which is vibrated by means of a wheel 17 having projections 18.  In another construction the piston 13 is fixed to the spring blade of an electric contact breaker in a similar manner to the hammer of an electric bell.  In Fig. 6, a device for varying the supply of spinning solution comprises a wheel 24 which is toothed or has peripheral openings, which is interposed in the path of the solution and is rapidly rotated.  Instead of employing a milled wheel for the waving process, the thread may be passed from a large smooth wheel to a small wheel arranged tangentially to the first wheel but not touching it, the adjacent parts of the two wheels turning in opposite directions.  The waved effect may also be produced by means of two blades rotating in opposite directions and striking the filament intermittently.
