Title: Improvements in method of moulding articles
IPC: B29C41/04
Filed: 1957-07-31
Abstract: 841,540. Moulding articles having concave paroboloidal surfaces. UNITED STATES RUBBER CO. July 31, 1957 [Oct. 19, 1956], No. 24238/57. Class 87(2). In a method of moulding a boot or shoe having a sole with a concave paraboloidal inner surface, a mould holding a solidifiable and gellable liquid is rotated about an axis inclined to the vertical during gelation of part of the liquid to form the upper portion of the boot or shoe, and, during gelation of the remainder of the liquid, is rotated about a vertical axis at such a speed that the inner surface of the sole portion assumes the desired paraboidal shape is formed by filling a mould 14, Figs. 4 and 5, with a plastisol, e.g. of polyvinyl chloride and dioctyl phthalate, and pouring out the plastisol to leave sufficient for forming the boot. The mould 14, which has a paraboloidal inner surface at the sole portion, is then clamped to a turntable 20 so as to be rotatable about the axis of the paraboloid by a variable speed motor carried by a platform 21. The latter is first tilted about a hinge 22 so that the axis of rotation of the mould is inclined at about 30 degrees to the horizontal, and the mould is rotated at about 30 r.p.m. whilst the upper portion of the mould is heated to gel some of the plastisol or to form the upper, whilst the remainder of the plastisol drains to the bottom of the mould. After an appropriate period the turntable 20 is made horizontal the rotation is stopped, and the mould 14 tilted so that the remaining liquid plastisol flows into the sole cavity. The mould 14 is then rotated about a vertical axis whilst the sole portion is heated to gel the plastisol. The rotation is then stopped and the heel cavity of the mould filled with plastisol which is gelled by heat to form the heel. Finally the whole mould is heated to fuse the plastisol, cooled, and the finished boot removed. Specification 726,784 is referred to.

Title: Improvements relating to the manufacture of sulphonic acids of the napthalene series
IPC: C07C309/43
Filed: 1937-09-10
Abstract: 2-Hydroxynaphthalene sulphonic acids are formed by heating until no more nitrogen is evolved, an aqueous solution or suspension of the diazo compound of 1-amino-2-hydroxynaphthalene sulphonic acids with normal sulphite, e.g. sodium sulphite in the presence or absence of a metal, e.g. copper powder, zinc or aluminium or a metal salt, e.g. copper sulphate.  By heating the product with water or acids, e.g. dilute mineral acid, e.g. sulphuric acid or strong organic sulphonic acids such as naphthalene sulphonic acid, the sulphonic acid group introduced in place of amino in position 1 is split off.  In examples: (1) 2-hydroxynaphthalene: 1-4-disulphonic acid is prepared by heating sodium 1-diazo-2-hydroxy naphthalene-4-sulphonate prepared by the process described in Specification 10235/04, [Class 2], with a solution of sodium sulphite and copper sulphate containing copper powder.  The hot liquid is filtered, acidified with hydrochloric acid and the product salted out; (2) 2-naphthol-1 : 6 - disulphonic acid is prepared from 1-diazo-2-hydroxynaphthalene-6-sulphonic acid made by the process described in Specification 10235/04 by treating with sulphite copper sulphate and copper powder; 1-diazo-2-naphthol - 4 : 6 - disulphonic acid behaves similarly; (3) 6-nitro-2-hydroxynaphthalene-1-4-disulphonic acid is obtained from the sodium salt of 6-nitro-1-diazo-2-hydroxynaphthalene-4-sulphonic acid obtained as described in Specification 15418/04, [Class 2], by heating with sulphite and copper powder.  The 6-nitro-2-hydroxy naphthalene - 1 : 4 - disulphonic acid may be reduced with iron to the corresponding amino compound; (4) the sodium salt of 6-bromo-2-hydroxy naphthalene-1 : 4-disulphonic acid is obtained when the sodium salt of 6-bromo - 1 - diazo - 2 - hydroxynaphthalene - 4-sulphonic acid made according to Specification 3508/11, [Class 2 (iii)], is treated with sodium sulphite, crystallized copper sulphate and copper powder. 6-Chloro-1-diazo-2-hydroxynaphthalene - 4 - sulphonic acid described in Specifications 20072/11 and 20073/11, [both in Class 2 (iii)], behaves analogously.

Title: Process of and apparatus for effecting local hardening of mass-production articles
IPC: C21D1/06
Filed: 1937-09-10
Abstract: 502,152. Hardening metal articles. SCHAURTE, W. T., and KAUFMANN, K. Sept. 10, 1937, No. 24730. Convention date, Sept. 10, 1936. [Class 72] Local hardening of mass-produced articles, such as knife-blades, needle points, and the heads and points of bolts and set-screws is carried out by inserting the articles into pockets in heat-conducting blocks and feeding them in the blocks at selected intervals to a heating device and immediately thereafter, in one step, to a chilling device, both devices acting on the exposed surfaces of the articles. An automatic apparatus for carrying out the process comprises a drum 7 carrying a number of rows of blocks 4 having jackets 5 for the reception of the articles, which are shown as set-screws the upper portions of the heads of which are to be hardened. By means of a cam-operated ratchet gear the drum is rotated in a step-by-step manner to bring the pockets opposite to a feeding-device 11, from which the set-screws are fed into them, and thence successively past burners 12 and chilling devices 13. The burner flames and the chilling sprays strike the heads of the set-screws centrally, and the sprays splash over the edges of the heads and the faces of the blocks without entering the gaps between them. The heating may be performed electrically by induction or resistance heaters. In treating knives, the knives are held in heat-conducting blocks with only the blades projecting and the heating may be performed by clamping the blades between copper jaws and passing a current through them.

Title: Thermal power plant
IPC: F28D7/16
Filed: 1974-06-05
Abstract: 1438605 Closed circuit gas turbine plant KRAFTWERK UNION A G 5 June 1974 [5 June 1973] 24993/74 Heading FIT [Also in Division G6]  In a closed gas circuit power plant having a compressor 5, heat source 1 e.g. a nuclear reactor, and heat consumer 2 e.g. a turbine, the tubes of a recuperative heat exchanger 3 and of a heat exchanger 4 for discharging heat from the circuit are contained in a common casing. In the nuclear plant shown, gas e.g. helium from compressor 5 passes via unions 11 into the outer channel of an assembly of coaxial tubes 12 and thence flows upwardly around reactor wall 25 to the outer channel of a coaxial tube assembly 13. The gas is then pre-heated as it flows downwardly through the tubes 14 of heat exchanger 3 into lower manifold 15 and upwardly through connecting tubes 15a into upper manifold 15 before flowing through the inner passage of assembly 13 to the interior of reactor 1. The gas is further heated therein before passing downwards through the inner passage of assembly 12 into turbine 2. The expanded gas leaves the latter through tube 16, 17 and enters heat exchanger 3 via the inner tube of a coaxial assembly 18 and a chamber 19. The gas flows upwards over the tubes 14, pre-heating the gas therein, and then radially inwards through passages 20 in a cylindrical dividing wall into a central space containing the tubes of heat exchanger 4. The latter has a hemispherical collecting chamber 22 supplied with water coolant via pipe 21, which coolant flows through the tubes before discharging through pipe 23. The gas cooled in the process flows through the outer tube of assembly 18, into pipes 24 and thence to compressor 5 to complete the cycle. The tubes of heat exchanger 4 are held only at their upper ends in a closure plug 26 and can therefore be drawn out of the concrete external container 10 in an upward direction. Similarly the tubes 14 of exchanger 3 are held only at their upper ends in a plate 7resting on an insert 7a and can also be withdrawn upwardly. Additional heat exchanger may be provided within container 10.

Title: Improvements in portable, internal-combustion actuated tamping machines or rammers
IPC: E01C19/36
Filed: 1931-09-08
Abstract: 373,884. Internal-combustion actuated rammers. JOHNSON, J. N., Wharfedene, Skipton Road, Ilkley, Yorkshire. Sept. 8, 1931, No. 25210., [Class 7 (ii).] In a portable tamping machine or rammer an auxiliary piston 8 is provided in the head of the combustion chamber to scavenge this chamber and draw in a fresh charge. The main piston 3 is connected by its rod 2 to the ram or tool 1; a spring 6 surrounding the piston rod bears on a liner 7 carried by an extension 5 of the cylinder 4. The extension acts as a fuel reservoir. Through ports 15 in the piston 8 are held closed by flap valves 14 during the expansion stroke. The piston is supported by rods 9 on a crosshead 10 which is carried by rods 11 passing through lugs 12 on the cylinder and lugs 17 on the piston. During the later part of the expansion stroke the lugs 17 strike buffer plates 18 on the rods 11 and carry the piston 8 away from the cylinder head ; the valves 14 open and the combustion products pass to the top of the piston 8. Detents 20 on the cylinders hold the rods 11 down until trip fingers 21 on the piston 3 release the detents ; the return movement of the main piston is effected by the spring 6. On release of the detents the springs 13 on the rods 11 return the piston 8 to its upper position, as shown, expelling the products through the exhaust passage 16 and drawing a new charge into the cylinder. In a modification the piston 8 is connected by linkage to a rod carried by the cylinder which rod according to the position of the piston either moves with the piston or is free thereof ; this with an actuating spring effects the displacement of the auxiliary piston.

Filed: 1962-07-02
Abstract: 943,587. Magnetic holding devices. W. BINDER, [trading as BINDER MAGNETE KOMM. GES.]. July 2, 1962 [Aug. 8, 1961], No. 25272/62. Heading H1P. The invention relates to a permanent magnet chuck comprising a polepiece assembly 1 consisting of soft iron bars 4 arranged side by. side with non-magnetic separators 3 between them and a magnet system 2 disposed beneath the polepiece assembly 1 and consisting of permanent magnets 12 arranged side by side and magnetized across their width in a direction parallel to the magnetic gripping surface 6 with soft iron bars 13 located between adjacent magnets 12, the polepiece assembly 1 and magnet system 2 being displaceable relatively to one another parallel to the direction of magnetization to render the chuck operative and inoperative. According to the invention, the cross section of the permanent magnets 12 is reduced from the base of the magnet system up to the polepiece assembly 1 and the cross section of the soft iron bars located between the magnets is correspondly increased. This enables the soft iron bars 4 to be worked near to saturation in the operative position, Fig. 3a, and in the inoperative position, Fig. 3b, enables the bars to completely short out the magnetic field.
