Title: Improvements in or relating to co-polymers of polysiloxanes containing carboxyphenylradicals and polyhydric alcohols
IPC: C08G77/42
Filed: 1950-04-04
Abstract: Polyesters are made from organopolysiloxanes having at least two carboxyphenyl groups in the molecule and glycerol, ethylene glycol or bis-(hydroxymethyl) dimethyl silane.  The siloxanes have from 1.9 to 3 organic radicals per silicon atom, each radical being carboxyphenyl, tolyl, methyl or phenyl and are reacted with the alcohols in proportions ranging from one part by weight of alcohol to 300 parts by weight of polysiloxane to 2.5 parts of alcohol to 1 part of polysiloxane.  In examples (1) to (3) tetramethyl-1.3-di-p-carboxyphenyl disiloxane was reacted with ethylene glycol, glycerol and bis-(hydroxymethyl) dimethylsilane respectively.  In example (1) the product was extracted with hot carbon tetrachloride.  Evaporation of the solvent gave a thermoplastic material capable of being drawn into threads.  The product of example (2) after heating adhered strongly to glass and was hard and flexible.  The product of example (3) was a liquid which after heating on glass gave a resinous coating with strong adhesion. In examples (4) a copolymer of tetramethyl-1.3-di-p-carboxyphenyldisiloxane and octamethylcyclotetrasiloxane, soluble in ether, was reacted in various proportions with glycerol to give products ranging from a viscous liquid to a firm gel; (5) a copolymer containing 1 carboxyphenyl group per 3900 silicon atoms and obtained by oxidizing with potassium permanganate a mixture of o-, m-, and p-isomers of tolylmethylsiloxane dissolved in pyridine, the copolymer being extracted with benzene which was subsequently evaporated, was heated with glycerol for 25 hours at 180 DEG  C. to form a gel; (6) a copolymer of tetramethyl-1.3 - di - p - carboxyphenyldisiloxane and tetramethyltetraphenyltetrasiloxane was reacted with glycerol to form a gel.  The products of the invention are useful as paint vehicles, coatings for glass and electrical insulation.  They may be modified by reacting with dibasic organic acids and polyfunctional amines. Specification 669,790 is referred to.

Title: Improvements in metallic screens and processes of making them
IPC: C25D1/10
Filed: 1938-03-22
Abstract: 512,856. Making perforated metal screens by electrodeposition; etching. NORRIS, Inc., E.O. March 22, 1938, Nos. 8774 and 8775. Convention dates, April 22, 1937, and Feb. 19, 1938. [Class 41] [Also in Groups XVI and XXII] A thin finely apertured metal sheet is provided with a reinforcement in the form of a coarse mesh screen by electrodeposition. In one method of manufacture metal is deposited in the form of a fine mesh screen on a matrix with depressions filled with insulating material. Areas of the screen are then covered with insulating ink leaving uncovered lanes on which further metal is deposited to form a reinforcing grid. The reinforced grid is then removed from the matrix. Alternatively the reinforcement may be applied after removal of the fine mesh screen from the matrix. In another method, after deposition of metal to form a fine mesh screen 16, Fig. 6, on a matrix 12 provided with depressions 13 filled with insulating material, a layer of copper 20 is deposited over the whole screen. Areas 21 are then stopped out and nickel is deposited over intersecting lanes 22. The stopping out material is then removed and the copper layer 20 is removed by etching, electrolytically or otherwise, except where protected by the overlying nickel ribs. In another method, the matrix 13, Fig. 9, is provided with intersecting grooves corresponding in position to the desired reinforcement. In the deposition of the grid 16 metal 27 is also deposited in the grooves so as to join up the sections of the grid. A layer 28 of copper is then deposited over the whole and is coated with a resist 30 except above the grooves. Nickel is then deposited in the intervening grooved lanes to form ribs 31 ; the resist is then removed and the copper layer 28 etched away except where protected by the nickel ribs. The screen on removal from the matrix is thus provided with reinforcing ribs on both sides. Suitable baths for etching copper are (1) a solution of potassium cyanide (2) a solution containg 2 1bs suphuric acid, 1 1b chromic acid to 10 gallons of water; these are inert to nickel.

Title: Process for the polymerisation of hydrocyanic acid
IPC: C01C3/08
Filed: 1962-03-07
Abstract: The polymerization of liquid hydrocyanic acid containing small quantities of water or of hydrocyanic acid in aqueous solution is performed in the presence of a basic catalyst and of a vanadate which is termed an accelerator. The vanadate, which may be ortho-, meta-, di-, penta- or poly-vanadate, may be added to the polymerization solution or formed in situ. Alkali metal, e.g. sodium, meta-vanadates are preferred, employed in a molar ratio with respect to the hydrocyanic acid of 1 : 20 to 1 : 6.  The basic catalyst may be ammonium, alkali metal or alkaline earth metal hydroxides and/or cyanides and/or cyanates.  The polymerization product combines reversibly to form complexes with metal salts and these complexes may be used to deposit the metals from solution. It may also be used as a nitrogenous fertilizer.

Abstract: 1463634 Surgical suturing appliances VSESOJUZ NI I ISPYTATEL INST MEDITSIN TEKH 4 March 1975 8974/75 Heading B4C [Also in Division A5] A surgical suturing device for suturing organs with metal staples comprises: two clamps 1, 2 connectable by a separable hinge 9 and locking hooks 10, each clamp comprising a pair of jaws, 3 and 4, 5 and 6 respectively, pivotally movable relative to each other; staple magazines 14 mounted on jaws 4, 5 of the clamps and having pushers 15 for ejecting staples towards dies 16 mounted on the respective opposed jaw 6, 3 on the other clamp; and means 13 for gripping an organ including toothed plates 19, 20 extending longitudinally of the jaws and movably mounted on each jaw. In use each of the clamps, e.g. clamp 2, Fig. 7 is secured to the organ adjacent the portion to be excised, with the organ clinched between butt surfaces 7 of the jaws of the clamp the jaws locking together by means of leaf spring 67. Movement of handles 91 of each jaw moves toothed plate 20 to grasp the walls of the clinched organ between teeth 21, 22 and releases cases 18 of the gripping means 13 to allow movement from the position shown in Fig. 7. The organ portion to be excised is then cut off adjacent teeth 21. The two clamps 1, 2 are now connected at hinge 9 and opposed butt surfaces 8 of the two clamps brought toward each other. Cam projections 28 on the gripping means 13 of opposed jaws 3 and 5, 4 and 6 move the gripping teeth toward the plane of their respective butt surfaces 8 and behind the plane of their respective butt surfaces 7, thus drawing the edges of the cut organs between the staple slots of the magazines 14 and the dies 16. The clamps 1, 2 are then locked together by hooks 10 and handles 53 pushed over safety projections 55 to move pushers 15 to eject the staples. A second embodiment (Figs. 19-31, not shown) generally similar to the first embodiment has an alternative form of gripping means. Each gripping means comprise a plurality of fixed teeth having aligned longitudinal through holes and a needle. When the organ is clinched by a clamp, the walls of the organ are crimped between the teeth of the jaws of a clamp, the teeth being relatively offset. The needles are then inserted into the through holes of each respective means to thereby transfix the walls of the organ. Further operations are similar to those for the first embodiment.
