Abstract: 1482245 Suction cleaners BAXTER TRAVENOL LABORATORIES Inc 26 June 1975 [1 July 1974] 27063/75 Heading A4F [Also in Division A5] A suction device, especially for keeping a field of surgery clear of blood, comprises a suction tip 10 having a plurality of holes therein and connected to a roller pump 20 for providing suction, said pump being controlled by means 30 remote from the suction tip and operated in response to pressure variations in a handle portion 14 which communicates with the controlling means through a tube 36. The means 30 provides a flow of air along tube 36, which air normally escapes through an aperture in the handle portion. When the aperture is manually obstructed, the pressure in tube 36 rises and a switch in the means 30 is actuated to start the pump. Alternatively, means 30 may provide suction in tube 36, the pressure in said tube falling on obstructing the aperture to thereby start the pump. In a modification, a resilient squeeze bulb is attached to the end of tube 36, squeezing of the bulb effecting an increased pressure to operate the pump. In another embodiment, tube 36 is attached to a tube portion (86) Fig. 6 (not shown), extending alongside tip 10 and having an aperture (84) at the bottom thereof. The tip is, in use, placed at the bottom of a surgical incision and as the blood level rises above aperture (84) the pressure in portion (86) and tube 36 rises to thereby actuate the pump, the pump being stopped when the liquid level drops to a predetermined value. When suction is applied, blood passes into tip 10 and is passed along lines 16, 22 to a reservior 24 where the blood is filtered and stored before being reinfused to the patient through line 26. Reservoir 24 has an air vent 25.

Abstract: 1,158,962. Preparing hexose-1,6- and pentose-1,5-diphosphates. BOEHRINGER MANNHEIM G.m.b.H. 13 June, 1967 [15 June, 1966], No. 27169/67. Heading C2C. Hexose-1,6- and pentose- 1 ,5-diphosphates are obtained by acylating a hexose-6-mono-phosphate or a pentose-5-monophosphate with an excess of an acylating agent, removing the excess of acylating agent, melting the residue, with gentle warming, with an excess of anhydrous ortho- and/or pyro-phosphoric acid, adding an alkaline lye to render the reaction product alkaline and then separating the desired diphosphate. The acylating agent may be a C 1 -C 4  fatty acid derivative, e.g. acetic acid or acetyl chloride and the acylation is preferably carried out at 0 to 120 C. in the presence of a condensation catalyst, e.g. zinc chloride, perchloric acid, pyridine or sodium acetate and an inert solvent may be present. The alkaline lye may be. an aqueous or alcoholic lye, and may be, e.g. ammonia or lithium hydroxide or an alcoholic solution of NaOH or KOH, a methanolic solution of NaOH being preferred. When alcoholic lye is used the corresponding salts of the sugar diphosphoric acids and of the ortho- and/or pyrophosphoric acids precipitate out and can be easily separated, e.g. by filtration or centrifugation and can be further purified, e.g. by dissolving the precipitated salts in hot water, adjusting the pH to 9À0, cooling to 0 C. to crystallize out the major portion of the orthophosphate as the dodecahydrate and removing the remainder in the form of magnesium ammonium phosphate by adding a water-soluble magnesium salt and then adding ammonia. The sugar diphosphate can then be separated from the residue, e.g. as the cyclohexyl ammonium salt. Specified sugar monophosphates for use as starting materials are glucose-, galactose- and mannose- 6-phosphates and arabinose-, ribose and xylose- 5-phosphates.

Title: Production of polymers
IPC: C08F2/06
Filed: 1953-10-05
Abstract: Cross-linked polyurethanes are produced by reacting (a) one or more saturated or unsaturated linear or branched chain hydroxy polyesters obtained by the reaction of one or more polyhydric alcohols with one or more saturated and/or unsaturated dicarboxylic acids with (b) organic polyisocyanates, in solution in one or more monovinyl and/or polyvinyl compounds which polymerize under the conditions of the reaction.  The polyesters are obtained from acids such as oxalic, succinic, sebacic, phthalic, adipic, and maleic acids, and polyhydric alcohols such as butanediol, butenediol, butinediol, glycerol, trimethylol propane, triethanolamine, pentaerythritol, ethylene glycol, butylene glycol, diethylene glycol, methyldiethanolamine, hexanediol and octanediol; the polyesters may be modified by aminoalcohols, diamines, monoalcohols, or higher fatty acids, e.g. linseed oil acids; when polyesters made from maleic acid are used these copolymerize with the vinyl compounds. Polyisocyanates specified are hexamethylene-1,6-diisocyanate, 4,41 - dicyclohexyl - methane-diisocyanate, toluylenediisocyanate, polyisocyanates obtained by reacting polyhydroxy compounds, e.g. hexanetriol, with diisocyanates, and polyisocyanates obtained by reacting polyesters containing hydroxy groups, with an excess of diisocyanates as described in Specification 742,501.  Vinyl compounds specified are styrene, esters of acrylic and methacrylic acids, e.g. methyl methacrylate, or mixtures thereof; the vinyl compounds may be used in the form of their liquid partial polymers.  The reaction is accelerated by the application of heat, and the addition of tertiary amines such as diethylaniline, hexahydrodimethylaniline, and N,N - diethanol - p - biphenylamine, which may be used in conjunction with benzoyl peroxide.  The reaction mixture may also contain inert substances such as carborundum, aluminium powder, sawdust, and glass wool. By carrying out the reaction in the presence of water or compounds containing carboxyl groups, e.g. carboxyl polyesters, carbon dioxide is evolved and a foamed product results.  Textile fabric may be coated with the reaction mixture which is heated to produce a polymeric coating and layers of textile fabric may be laminated in this way.  The process may also be applied to the production of mouldings, abrasive articles, and coatings generally.
