Title: Method of and means for producing socket-type head screws
IPC: B21K1/46
Filed: 1955-08-20
Abstract: 797,546. Making socket head screws. CONSTABLE, A. Aug. 20, 1956 [Aug. 20, 1955], No. 24043/55. Class 83 (4). A socket head type screw, Fig. 3 (not shown), is made by cold-extruding a metal blank whose maximum outer periphery corresponds to the outer periphery of the head of the screw, to form the head and shank of the screw, and simultaneously punching the socket in the head, the metal displaced during the punching being extruded into the shank to effect a lengthening thereof. For producing a countersunk head screw, a cylindrical blank, Fig. 2 (not shown), is inserted in a die cavity 5 and is extruded therefrom into cavities 7, 8 by a punch 9 carried by a main slide 13. An auxiliary punch 10 moves initially with the punch 9 and at a certain point in the stroke the auxiliary punch is moved forwardly of the punch 9 to form the socket. The auxiliary punch is carried by an auxiliary slide 14 actuated through a lever 11 by a cam 15. Alternatively the auxiliary slide 14 may be actuated by a bell-crank lever pivoted on the main slide 13 and adapted to engage an inclined block mounted adjacent the main slide. Cheese head screws are produced in two stages, the socket being punched in the final stage.

Abstract: 1,060,987. Making composite tubes; welding by pressure; bending and covering. GUSTINBACON MANUFACTURING CO. June 10, 1964, No. 24107/64. Headings B3A, B3E and B3R. A method of applying a metal foil skin, e.g. of aluminium, to the external surface of a tubular duet of insulating material, e.g. glass fibre, comprises placing the duct on a rotatable mandrel, feeding one end of the foil to the mandrel and clamping it thereto by means of an elongated anvil strip on the mandrel, rotating the mandrel until a double thickness of foil overlies the anvil strip and forming a seam, e.g. by ultrasonic welding in the foil at the overlap on the anvil strip. Apparatus for carrying out the method comprises a vertically adjustable uncoiling unit which may include a drag brake on the foil coil supporting shaft 21, a support frame 29, 30 housing adjustable cutter bar support beams .(34) (Fig. 2, not shown), feed rollers (41), (42), preferably rubber covered, the roller 42 being motor driven whilst the upper roller 41 is vertically adjustable by hydraulic means (45) and a mandrel assembly 70. An hydraulically adjustable tensioning roller (47) is mounted on a rotatable shaft 48 on the framework. The mandrel 70 is detachably mounted on a driven shaft 67 which is fixed to a platform assembly 62 slidably mounted on shafts 55 and adjustable therealong by a leadscrew 58 and handle 60. The mandrel comprises relieved portions (75) (Fig. 8, not shown) in which are mounted strips (74), a member (80) having bifurcated ends between which is pivotally mounted a key (83) which engages an arcuately curved steel anvil strip 85 mounted parallel to the mandrel and pivotally attached thereto by a shaft 86. The mandrel is supported at its free end by a centre mounted on an adjustable arm pivotable about a vertical axis (Fig. 6, not shown). In operation aluminium foil is fed by the rollers 41, 42 over a tensioning roller 47 to the mandrel, a glass fibre duct is slid over the mandrel, the anvil strip 85 is swung against the duct to clamp the leading end of the foil thereagainst. The mandrel is then rotated through 540 degrees to completely cover the duct and produce a double thickness over the anvil. The overlapping foil is subsequently tensioned by movement of the roller (47) prior to being welded by a conventional ultrasonic welding device comprising a head pivotally mounted on a vertically adjustable platform which is traversed along the foil width by a motordriven leadscrew 123 and whilst a welding contact wheel (129) (Fig. 2, not shown) on the head is hydraulically advanced into engagement with the foil. Two welding passes may be made. Following the welding operations the mandrel is rotated 90 degrees in an anti-clockwise direction and a tear (107) is rotated to sever the foil from above the seam on the anvil. The mandrel shaft is subsequently reset by rotation through 450 degrees in an anti-clockwise direction.

Title: Improvements in or relating to the treatment of aliphatic acids
IPC: C07C51/48
Filed: 1929-08-12
Abstract: 338,187. Dreyfus, H. Aug. 12, 1929. Acetic, propionic, and other lower aliphatic acids are concentreated by extracting the aqueous solution with a solvent, and then adding a liquid such as a hydrocrabon or a halogenated hydrocarbon to the extract to precipitate the dissolved water, which is then removed in the, liquid state. The solvent may be any of those mentioned in Specification 283,702, for instance ether, ethylacetate, or acetone oil, and may be used in admixture with a hydrocarbon or halogenated hydrocarbon such as methylene chloride or carbon tetrachloride, and salts may also be used to limit the solubility of the solvent in water. The precipitant for the water in the extract may be petroleum distillates, benzene, carbon tetrachloride, chloroform, dichlorethylene, trichlorethylene, and acetylene tetrachloride; and the water precipitating liquid may be the same as that used in admixture with the solvent. The extraction may be effected in a column in countercurrent, and either or both liquids may be introduced into the column through sprays or nozzles; or the solvent may be admitted as vapour, and the tower may be packed with suitable filling and may be provided with a heating-jacket. The precipitation of the water may be effected in a suitable mixing apparatus, for example, a packed tower or a vessel with an agitator. The precipitated water may be separated in a settling tank and may be further treated to recover its content of acid. The mixture of acid, solvent, and waterprecipitant may be separated by distillation, and both the solvent and water-precipitant may form azeotropic mixtures with water, so that it is not necessary to precipitate and separate in liquid form all the water in the original dilute acid; and further water may be carried off by returning the condensate to the still after separating the aqueous loyer. In an example, acetic acid of 30 per cent strength is extracted in counter-current with ether as described in Specification 283,702, the extract, containing 30 per cent water, is mixed with benzene, and the mixture led to a separator, the non-aqueous layer being treated in a column still, ether being distilled off, the residue being treated in a second still to remove the benezene, which carries off some acetic acid and any remaining water. Specification 320,606 also is referred to.
