Title: Cationic exchangers based on sulphonated polystyrene resins
Inventor: MORGNER MANFRED
IPC: C08F8/34
Filed: 1961-10-19
Abstract: Cationic exchangers are produced by sulphonating polystyrene cross-linked with divinylbenzene by mixing in a closed rotating vessel the particulate resin with that amount of a swelling agent which is only so great that there is no liquid phase present during the swelling process and allowing this mixture to remain in the closed rotating vessel until the formation of an equilibrium between the gaseous and absorbed phase of the swelling agent and then sulphonating this mixture with a chlorosulphonic acid-sulphuric acid (monohydrate) mixture for at most 4 1/2 hours.  The swelling agent may be dichloromethane and/or -ethane. The copolymer to sulphonation mixture, e.g. 1 part chlorosulphonic acid to 2-10 parts sulphuric acid, ratio may be 1:6. 30% or more of the swelling agent may be recovered during the sulphonation.  The sulphonation product may be washed with concentrated aqueous sodium sulphate and then water until neutral. The sulphonation mixture may be separated from the sulphonation product, the chlorosulphonic acid replenished and the mixture used again.
Patent GB-757878-A (GB)
Title: Improvements relating to circulatory fluid pressure power steering mechanisms for motor vehicles
IPC: B62D5/06
Filed: 1954-12-30
Abstract: 757,878. Fluid-pressure servomotor control systems. GENERAL MOTORS CORPORATION. Dec. 30, 1954 [Jan. 26, 1954], No. 37666/54. Class 135. [Also in Group XXXI] A power steering mechanism for a motor vehicle comprises a cylinder 100, Fig. 2, having a doubleacting piston 98 and a piston rod 104, fluid under pressure being directed to one or other end of the cylinder 100 by the relative movement of a valve element 38, Fig. 4, in a valve casing 12, the valve element being extended into a chamber 82, Fig. 4a, the extension having reaction surfaces to resist movement in either direction, the effective area of one reaction surface being greater than that of the other so as to compensate for the effect of the piston rod 104 in reducing the area of the piston for one direction of its movement as compared with the other. As shown, the arm 19, Fig. 1, is rocked by the steering column and carries a ball stud 59, Fig. 4, contained by bearing blocks 58 in a sleeve 56 slidable in-housing 14; a helical spring 60 is guided on a stud 64 whose head 62 abuts plug 52 and a round face of a flange 50 on extension 48 of a rod 46 passing through the valve spool 38 and gripping the valve spool by nut 92. Movement of arm 19 thus results in movement of spool 38, thus opening one or other of ports 72, 74 for fluid under pressure to flow from pipe 26 to either pipe 71, 73 to appropriately actuate piston 98. Since the piston-rod 104 reduces the effective area of piston 98 on one side, a greater manual force is required to produce movement of the piston 98 in the direction of the piston rod; to compensate for this, the spool 38 is stepped at 108, and the centring spring 84 is seated on seals 86 of different area, so that the fluid pressure entering from pipes 26, 78, 80 encounters a reaction surface compounded of the larger seal 86 less the step 108 for a movement of the spool to the left, but for a movement to the right the reaction surface is larger, being the sum of the area of the smaller seal 86 and the step 108. The operator thus encounters the same resistance for either direction of turn, while the re-centring rate is the same for either direction of turn. Alternatively, the valve spool may be tapered within the chamber; or the chamber may be stepped or tapered, and the valve spool be of constant diameter. The system may be operated hydraulically, pneumatically or by vacuum.

Title: Improvements relating to the dividing and balling of plastic materials such as dough
IPC: A21C5/04
Filed: 1930-12-13
Abstract: 368,851. Moulding dough &c. SCHIFF, S., Reading Road, Cincinnati, Ohio, U.S.A. Dec. 13, 1930, No. 37697. [Class 87 (ii).] In a combined divider and baller for plastic material such as dough, the rotary kneading wheel 16 is surrounded by a stationary kneading ring 10 and co-operates with kneading plates 21 to form the divided dough into balls, the division being effected in plunger-containing casings 8 carried by the wheel 16 and receiving dough from an oscillating auxiliary hopper 7 fed from a main hopper 13 through a guide 14 which is mounted onan arm 17 to be swingable out of the operative position. The dough is fed into the chamber formed by the descent of the plunger 9, a suction plunger 760 creating a vacuum in the chamber 37 which, by means described below, is put into communication with the dough chamber 8 to draw off air from the dough. The relative movement of the hopper 7 and the chamber 8 then partially closes the communication between them, and the plunger 9 rises slightly to return a portion of the dough to the hopper under slight compression. The dough is then, by further relative movement, completely severed, and the plunger 9 rises to position the divided dough on the level of the top of the wheel 16 from which it is swept, into the balling devices, by a spring- returned lever 61 pivoted at 65 to the wheel 16, contacting with a fixed stop 64. The plungers 9,760 are actuated by a cam track A, and during the downward movement the walls of the chamber 8 are moved laterally away from the plunger 9 to connect the spaces 8, 37. This is effected as shown in Fig. 4, by forming the walls in two L-shaped portions 39, 40 slidable in guides 41. Each wall portion is screwed to receive right- and left-handed screws 43 connected by and oscillated by a yoke 44 having a bearing portion 46' engaged by the rotary cam C. With this arrangement, the walls are withdrawn from the plunger during its descent and closed against the plunger during its ascent. The hopper 7, which has a projecting skirt 60, is oscillated by a roller on a lever 53 engaging the cam groove 52, the lever 53 carrying a quadrant meshing with a pinion or quadrant on the shaft 57 of the hopper. The cam A is adjustable to vary the volume of the dough divided, this being effected by making the cam in two semicircular halves, one half being vertically adjustable. A latch 79 permits the plunger 760 to be removed from its chamber 37 which can then be cleaned out.

Title: Method of refining nickel copper matte
IPC: C22B23/02
Filed: 1928-12-24
Abstract: 303,066. Lathe, F. E. Dec. 27, 1927, [Convention date]. Nickel, copper, and precious metals, obtaining. -Copper-nickel matte, prior to being leached with acid, for instance with sulphuric acid, to dissolve the nickel, is rapidly cooled as by granulation in water; additionally or alternatively a substantial amount, that is to say 2-10 per cent, of iron sulphide may be left in the matte during its customary treatment in a converter to remove iron and a part of the sulphur. By these means the rate and completeness of solution in acid of the nickel sulphide is increased, and its separation from the copper is rendered almost complete. The acid leach may be effected at 80-100‹ C. on the counter current principle, and the iron present in the nickel sulphate solution obtained may be removed by calcium, sodium, or nickel carbonate or nickel hydroxide with oxidation by air or manganese dioxide. Nickel may be obtained by electrolysis of the purified sulphate solution using insoluble anodes. The residue of copper and precious metal sulphides may be blown in a converter to obtain the metals, the copper being refined electrolytically, and the precious metals, including gold. silver, platinum, palladium, iridium, rhodium, ruthenium, and osmium, be obtained as a concentrate from the anode residues.
