Filed: 1926-02-18
Abstract: 264,345. Isaac, B. A., and Frank, C. A. Feb. 18, 1926. Closure members, loose-ball.-In a loose ball valve operated by a screw or floating ball, the ball 4 is mounted in a cup 5 having an upstanding pin 6 freely engaged in the end of the operating spindle 8, and the walls of the cup are made sufficiently deep to prevent the escape of the ball from the cup when the ball lifts under the action of fluid pressure, and also to make contact with the seating in the closed position in order to prevent the ball from being unduly crushed or forced down upon its seating. In order to minimize surface contact between the ball and the cup, the wall of the cup is cut away to form fingers 9, as shown: this also facilitates the rotation of the ball by friction of the liquid and reduces the obstruction to the passage of the liquid.

Abstract: 986,217. Bellows; mechanical seals; expansion joints. CRANE PACKING Ltd. Jan. 21, 1964 [Feb. 6, 1963], No. 4928/63. Headings F2B and F2G. A flexible bellows assembly is formed in situ by circumferentially wrapping on to one another different layers comprising one or more strips 7, 9 of metal sheet or mesh and at least one layer 8 of fabric, synthetic resin, rubber, or fabric-reinforced rubber or synthetic resin. The bellows may have one or more V-shaped convolutions and may be used in forming flexible pipe sections or for urging a rubber, reinforced resin or carbon sealing ring 4 held in a non-rotatable split metal carrier 5 against a rotatable seal member 1 secured to a carrier 3 rotating with a ship's propeller shaft 2. As shown, a metal strip 7, which may have transverse slots 7a, slits or ribs cut or pressed into it, is secured round the shaft with its inturned edges engaging in grooves in the carrier 5 and in a stationary mounting 6 associated with the ship's stern tube, the ends of the strap being brought together by a metal clip. The strip 7 is then wrapped with an extruded rubber or synthetic plastic layer or with a sealing strip 8 of P.V.C. reinforced with knitted cotton which may be wrapped two or more times round and has its outer end held by a contact adhesive. A further metal strip 9 is then wrapped round and the ends of the assembly are secured on to the carriers and the mounting 6 by heavy metal strips 10 provided with tensioning bolts. A pressure sensitive adhesive may be used between the layers of synthetic plastic or rubberized fabric. For protection against corrosion, the bellows assembly may be covered with a layer of rubber applied either with adhesives after completion of the assembly or by extrusion around the metal 7, 9. The fabric reinforced strip 8 may be protected by first wrapping the strip 7 with unsintered or sintered P.T.F.E. tape to form a barrier layer between the rubber and the strip 7 on the side in contact with corrosive liquid.

Title: Improvements in and relating to the production of omega-amino nonanoic acid
Inventor: CARPENTER ALBERT STANLEY
Filed: 1953-02-23
Abstract: o -Amino nonanoic acid is prepared by reacting an unsaturated acid occurring naturally in vegetable oils and having the general formula R-CH = CH(CH2)7COOH, wherein R is an aliphatic monovalent radical, with ammonia to form the corresponding nitrile of the acid, oxidising the nitrile to form azelaic acid seminitrile CN.(CH2)7COOH, together with an acid R.COOH as by-product, either by reacting the nitrile with ozone with concurrent treatment with water or by reacting the nitrile with ozone, subsequently decomposing the resulting ozonide of the acid nitrile with water to form a mixture of acids and aldehydes and oxidizing the aldehyde portion thereof to the corresponding acids, and hydrogenating the semi-nitrile in the presence of a hydrogenation catalyst to the desired amino-nonanoic acid.  In examples (1) oleic acid is heated with ammonia at about 300 DEG  C. and the resulting nitrile ozonized in ethyl chloride at -40 DEG  C.; the oleonitrile ozonide is refluxed with water, excess sodium carbonate added and the aqueous layer containing the sodium salts of pelargonic acid and azelaic acid semi-nitrile separated from the insoluble pelargonic aldehyde and o -cyanooctanol which are oxidized with oxygen at 120-140 DEG  C. in presence of ferric oxide and the product extracted with aqueous sodium carbonate to provide another solution of sodium salts of the acids; the two solutions are acidified and the liberated pelargonic acid and azelaic acid semi-nitrile separated; the nitrile is hydrogenated in alcoholic solution to aminononanoic acid under pressure in presence of ammonia and a Raney nickel catalyst; (2) oleonitrile is produced as in (1) and ozonized in aqueous ethyl acetate at 70 DEG  C.; pelargonic acid and azelaic acid semi-nitrile are recovered from the product and the latter hydrogenated as in (1).  In place of oleic acid, there may be used ricinoleic, linoleic and linolenic acids.  According to the Provisional Specification, R is any monovalent radical.

Abstract: 747,791. Forging-machines. CONCRETE PATENTS, Ltd. Feb. 23, 1954, No. 5354/54. Class 83 (4). A machine for cold upsetting a wire 2 comprises a vice 3, 4, having a movable jaw 4 actuated by a hydraulic piston 8, and an upsetting press having a hydraulic piston 12 subject to a permanent restoring force, e.g. by springs 15, 16, both pistons being supplied with pressure liquid from a pump 9 whose delivery circuit includes a safety valve 18, the ratio of the cross-sectional area of the vice piston 8 to that of the press piston 12 being greater than the ratio of the resistance to no-load movement of the vice jaw 4 to the restoring force on the press piston and also greater than the inverse of the minimum friction coefficient between the vice and any wire to be upset. This ensures that the press piston 12 does not move until the wire is gripped by the vice and also that the wire does not slip in the vice. A pressure release valve 29 is provided. In another embodiment for forming the upset intermediate the ends of the wire, a second vice 20, 21, Fig. 2 (not shown) which is identical with the vice 3, 4, is adapted to grip the wire to the right of the vice 3, 4, and is moved by the piston 12. This second vice is operated by a hydraulic piston whose cross-sectional area is the same as that of the piston 8. The press piston is hollow to allow the wire to pass therethrough.
