Abstract: 1,179,222. Polyurethanes. FARBENFABRIKEN BAYER A.G. 25 March, 1968 [25 March, 1967], No. 14208/68. Heading C3R. Polyurethanes are prepared by reacting a diisocyanate, a compound of M.W. below 800 containing at least two reactive hydrogen atoms and a mixture of a hydroxyl-containing dicarboxylic acid based polyester of M.W. 1000 to 3000 and a hydroxyl-containing hexanediol-1,6- polycarbonate, the proportion of hexanediol-1,6- polycarbonate being 10 to 50% by weight based on the total amount of polyester and polycarbonate. Polyesters based on adipic acid, particularly ethylene glycol-adipic acid, ethylene glycol-butane diol- 1,4-adipic acid and neopentyl glycol-hexanediol-1,6-adipic acid polyesters are preferred. The diisocyanate is preferably 1,5-naphthylene diisocyanate, 4,4<SP>1</SP>-diphenylmethane diisocyanate, m- and p-phenylene diisocyanate, 2,4- and 2,6-toluylene diisocyanates. Suitable chain lengthening agents are glycols when the reaction is carried out in the absence of solvents and diamines, hydrazine or dihydrazides when a solvent is used. Water may also be used as a chain lengthening agent. A prepolymer may first be formed from the diisocyanate and mixture of polyhydroxyl compounds which prepolymer may then be chainlengthened or else the three components may be reacted in one step. Suitable solvents are dimethylformamide, dimethylacetamide and dimethylsulphoxide. The resulting polyurethanes may be cross-linked by reaction with sulphur, peroxides, formaldehyde or diisocyanates. Films and filaments may be produced from the polyurethanes when the latter are produced in solution by chain-lengthening with diamines, hydrazine or dihydrazides.

Title: Improvements in or relating to the manufacture of decorative leaf
IPC: B44C5/06
Filed: 1920-05-26
Abstract: 165,307. Fichtmueller, J. A. C. May 26, 1920. Bronze and colour foils.-In processes of manufacturing decorative leaf of the kind described in Specification 27273/10 in which metallic or other colouring-matter incorporated with a binding material is applied to a backing previously coated with size or other material which is subsequently loosened so that the leaf may be separated from the backing, the leaf is formed on a long strip of backing, preferably paper, and after the loosening treatment the leaf and backing are rolled up, the end of the leaf is separated from its backing and caused to adhere to the surface of the next convolution of the backing, so that by unrolling the free end of the latter the leaf is transferred in reversed manner to the other side of the backing from that on which it was formed. The leaf and backing may then be subjected to a continuous treatment to remove any remaining size, and the leaf may be caused to adhere to the backing or other paper strip. A water-soluble size is preferably employed, and a roll of leaf and backing A, Fig. I, is passed through a tank of water B and formed into a roll C with the backing a, Fig. 3, on the outside. The end of the leaf a<1> is sepaiated from the backing a and is pressed on to the back h of the backing of the next convolution. On further unwinding the backing, the roll is unwound with the surfaces previously in conact on the outside and vice versa. The separate leaf together with the backing is now passed through a tank of water D to dissolve any remaining size, then against a rubber wiper F, and is wound on to a spool E together with absorbent blotting-paper from a roll G. In the apparatus shown, the spools may be removably mounted and may be rotated by hand or mechanical means; rollers b, d may be provided to keep the strips below the surface of the water in the tanks B, D respectively, and an additional spool A<1> may be provided for passing the strips twice through the tank B. An adhesive adapted to become moist on being heated may be incorporated in the leaf body so that after the leaf is dried it may be passed together with a paper strip between hot rollers or pressed on a hot surface so as to adhere to the paper, for example to make gold tipped paper for cigarettes; or the leaf may in the same way be made to adhere lightly to the backing itself for issue into commerce. Celluloid lacquer may be used as the binding-agent, and resinous gum as the adhesive, also wax may be used in place of a water-soluble size.

Filed: 1942-10-16
Abstract: 560,796. Grabs; raising sunken objects. WATSON, A. J. G. Oct. 16, 1942, No. 14525. [Classes 78 (iv) and 78 (v)] [Also in Group XXI] Relates to a grab of the type comprising jaws 31, Fig. 2, operatively connected with a piston 24 and arranged to engage the object to be raised when the piston is moved upwards in its cylinder 22 by pneumatic means creating a difference in air pressure on opposite sides of the piston. According to the invention, the cylinder has a jacket to contain air for increasing the buoyancy of the grab when it is used for salvaging submerged objects. The arrangement shown, for raising a sunken submarine 33, Fig. 1, comprises an armourplated, cigar-shaped drum 10 supported by cables 11, 11a from two ships 12, 12a, a third ship 17 supporting a diving-bell 18 in telephone communication with the three ships and carrying a searchlight to illuminate the sea-bed. Each cable 11, 11a is led into a hawse-hole 13, Fig. 4, in the ship through rings 15 on a leafspring 14 which is supported by a bracket 16 and a projecting part 13a of the hawse-hole frame. The drum 10 is formed with inner and outer cylindrical shells 34, 35, between which the pivots 30 of the jaws 31 are arranged, and carries two identical grab devices 21, Fig. 1. For operating each grab, arms 29 integral with the jaws have pins 28 engaging slots 27 or guides in a bar 26 on the piston-rod 25, the spaces above and below the piston 24 being connected respectively by a pipe 41 to a vacuum pump and by a pipe 40 to an air pump on the ship 17, the ship connections between the pipes 40, 41 being reversable. Also extending from the ship 17 are pipes 42, 43, 45 by which, .respectively, (a) water can be pumped into and out of the space between the shells, (b) compressed air can be admitted to the space, and (c) air can escape when water is pumped in. In use, the drum is filled with water and lowered over the object to be raised, the ships being manoeuvred in accordance with instructions telephoned by a person in the diving- bell. The jaws are then closed and air is pumped into and water pumped out of the drum which is then raised by the cables 11, 11a and towed to port. The drum may be fitted with a low-powered engine to drive a screw to make the drum manoeuvrable when in port, e.g. to allow it to enter a dry dock, the engine driving compressed-air and vacuum pumps instead of using the pipes 40, 41, 43, 45.
