The polymer contains at least 70 mole per cent of the above units and the remaining units may be derived from the polymerization of vinyl esters with ethylene, vinyl chloride, ketones and ethers, and alkyl and acrylic acid esters.  Examples describe the preparation of partial vinyl m-nitrocinnamate and p-methoxycinnamates and their complete esterification with succinic or phthalic anhydride; and the preparation of a vinyl cinnamate-vinyl maleate copolymer; a vinyl-cinnamate-vinyl 3-nitrophthalate copolymer; a vinyl cinnamatevinyl 4-tetrahydropthalate copolymer; an ethylene-vinyl cinnamate-vinyl hydrogensuccinate terpolymer; a copolymer of vinyl acetate and a vinyl 3,azidophthalate; a vinyl toluene: maleic anhydride copolymer; the condensation of polyvinyl acetophenone with the sodium salt of p-carboxymethyl ether of benzaldehyde; and a reaction product of p-carboxymethoxy-p1-(b -hydroxyethony)-chalcone with a styrenemaleic anhydride copolymer.  The polymers are dissolved in an aqueous alkaline solution or in an organic solvent together with up to 10% of a sensitizing agent and coated upon a printing support for exposure to ultra-violet light.

Title: Of gaseous currents manufacture of fibres from an attenuable material by means
IPC: D01D5/08
Filed: 1978-05-30
Abstract: The process consists in generating at least one pair of gas jets (a - a) with kinetic energies per unit volume and dimensions which are substantially equal, whose axes are situated practically in the same plane, the two jets converging to form a combined flow after their impact and in conveying the ductile substance (S) into a zone of gases induced by one of the two jets, which zone is situated outside the angle included between these jets. In a second stage the combined flow enters a main gas stream (10) to form a zone of interaction into which the partially drawn fibre is introduced in order to be subjected to additional drawing therein. The process is employed especially for making fibres from glass. <IMAGE>

Patent GB-383992-A (GB)
Title: Improvements in or relating to extracts obtainable from mammalian suprarenal glands
Filed: 1931-08-28
Abstract: An extract of the cortex of the suprarenal gland is obtained by treating the cortex with an organic liquid which is a solvent for the active principle or hormone, and is preferably also a water solvent, treating the material dissolved with a lipoid solvent and, after separation from the solid residue, treating the solution by filtration through a zeolite or with alkali, thereby obtaining a material which is capable of alleviating the effects of adrenal insufficiency.  In a practical application ground tissue is extracted with 95 per cent ethyl alcohol and the extracts are concentrated in vacuo, the aqueous residue is shaken with benzene and the separated benzene solution is evaporated in vacuo.  The residue from which the benzene has been distilled is extracted with acetone and the acetone distilled off in vacuo. The residue is mixed with petroleum ether and 70 per cent alcohol and the alcoholic solution is repeatedly extracted with petroleum ether.  The 70 per cent alcoholic solution so obtained is concentrated and mixed with water and decanted from oily residue or the alcoholic solution may be first further purified by filtration through a zeolite.  This filtration may be carried out at an earlier stage in the process.  A method of purification alternative to the filtration is by treatment of the 70 per cent alcoholic solution with caustic alkali.  The aqueous solution obtained as above is suitable for injections and is substantially free from epinephrine and other undesirable substances.
