Title: Continuous methods of and means for the production of hollow bodies by the centrifugal process
IPC: B22D13/10
Filed: 1947-10-27
Abstract: 632,104. Foundry plant. STANTON IRONWORKS CO., Ltd., and WILSON, P. H. Oct. 27, 1947, No. 28649. [Class 83 (i)] In a cyclic process for producing hollow bodies by centrifugal casting, a number of heated moulds are fed successively to a centrifugal casting-machine where the body is cast and the mould and body then pass to a station where the casting is ejected and the mould allowed to continue its path through a cooling zone and back to the casting-machine, the moulds remaining horizontal throughout the process and their translational movements being lateral relatively to' their axes. The passage of the moulds to and from the casting- machine is controlled by two inclined gravity conveyers 2, 3, Fig. 1, coupled at their ends by electrically-controlled hydraulic lifts 4, 5. In a modified form, Fig. 3, moulds from an upper horizontal conveyer section 19 are carried down a vertical section 20, along a lower horizontal section 22 within a cooling tunnel 23, up another vertical section 21 to another upper horizontal section 24 from which they are fed one at a time to a mould-charging apparatus c. This comprises horizontal links 14 with depressions for receiving two moulds 17, 18 mounted on rotating arms 10, 11. If, in the position shown in Fig. 3, a pipe has just been cast in the mould 18 and the mould 17 has just been fed on to the links 14 from the conveyer 24, then the arms 10, 11 are electrically operated so that the mould 18 is deposited on the conveyer 19 and the mould 17 is positioned ready for casting. As the arms 10, 11 complete a revolution, the left-hand depression comes to rest beneath the mould 17 and another mould is deposited in the right-hand depression from the conveyer 24, and the cycle is complete. The moulds with the castings therein are next fed to an extractor station at which a ram-head 26, Fig. 4, operated by a hydraulic cylinder 25, pushes the cast pipe out of the mould on to a supporting mandrel 28, which may be turned 90 degrees about an axis at right-angles to its own axis so as to deposit the casting on to another conveyer. Specification 625,209 is referred to.

Title: Process for purifying tin ores and other stanniferous materials
IPC: C22B25/02
Filed: 1927-10-27
Abstract: 304,829. Witter, W., Lissauer, M., Lissauer, H., and Griesmann, B., (trading as Lissauer et Cie, M.). Oct. 27, 1927. Reasting; treating ores to remove undesired constituents.-Tin ores and other stanniferous materials are mixed with carbon or other reducing substances and heated in stages from 200- 800‹ C. to remove arsenic, antimony, lead and bismuth one after another by volatilization without affecting the tin. Instead of solid or liquid reducing-agents, gases may be employed. By gradually increasing the temperature and maintaining it at definite levels for a certain time, it is possible to eliminate the above impurities and partly also zinc, one after the other. Copper and silver can be recovered by adding sodium chloride &c. before or after termination of the treatment. A tin ore containing lead, copper and other impurities may be mixed with powdered coal sufficient for reduction of metal oxides except the tin oxide, a small excess of coal being present so that when a final temperature of 800‹ C. is reached there still remains a portion of coal capable of reacting. The ore and coal are then transferred to a rotary drum .furnace or multiplestage furnace and raised to a tempterature at which arsenic escapes. The heating is continued until antimony escapes and so on. Zones may be arranged in the furnace in which temperatures may be maintained during time intervals and inlet and discharge temperatures should not exceed 200‹ C. and 800‹ C. respectively. Chloridizing agents can be added to the hot material, or a second apparatus may be used for the removal of copper and silver which can be collected separately from the other products.

Abstract: 823,212. Controlling and actuating by sound and ultrasonic waves. PHILIPS ELECTRICAL INDUSTRIES Ltd. Oct. 11, 1955 [Oct. 14, 1954], No. 28925/55. Class 118 (2). [Also in Group XXXV and XL (c)] Ultrasonic testing of welding conditions (see Group XL (c)) is used to provide automatic switching of the welding current. Electrodes 3 and 5 carry a transmitting transducer 2 and receiving transducer 6 respectively and when the pressure of the electrodes 3 and 5 on the workpiece 4 is sufficient the received ultrasonic oscillations are of such amplitude as to cause diode 8 to conduct and a pulse is fed to electronic switch 20 which then supplies welding current to the electrodes 3 and 5. When the joint in workpiece 4 fuses there is a rise in strength of the received ultrasonic oscillations and a diode 13 conducts to pulse switch 20 and stop the welding current. The bias voltages of diodes 8 and 13 are adjustable by potentiometers 9 and 14 respectively. In an alternative embodiment (Fig. 2, not shown) the ultrasonic oscillations are modulated at 50 c/s. and a somewhat simplified arrangement of diodes and trigger circuits is used. In a further embodiment (Figs. 3 and 4, not shown) a single quartz crystal is mounted on electrode 3 only and a reflection technique is utilized in which the ultrasonic vibrations are pulsed at 5 kc/s. and detection of echoes at the electrode and workpiece junctions controls switching of the welding current (see Group XL (c)).

Abstract: 441,894. Batteries. GORDON, C. J., 10, Liberia Road, Highbury, London. Oct. 12, 1934, Nos. 29308/34 and 27052 /35. [Class 53] A primary cell has a magnesium electrode consisting of a group of elements each of which is wrapped in a layer of fibrous material. The elements are held together and placed in a casing so that spaces are provided between the elements and the casing and between the elements themselves. The fibrous layers extend into these spaces and are there exposed to the air which serves to depolarize the cell. The second electrode partly surrounds and is in contact with the fibrous layer covering each magnesium element. Figs. 1 and 2 show a single cell having a magnesium electrode consisting of four elements 1 each surrounded by wood wool and surrounded by a split carbon tube 3 forming the second electrode. The four magnesium elements are joined in parallel by wires 15 and the carbon tubes are joined in parallel by a strip of copper gauze 13, a connection being made to the gauze by a wire 16. The wires 15, 16 are connected to sockets moulded in an insulating cover 17. The fibrous layers project through the slits in the carbon elements and thus extend into the central space 14, Fig. 2, which is in contact with the outer air through holes 18 in the casing 9. The lower ends of the fibrous layers are in contact with a pad of cotton wool 20 which extends downwards into water 7 contained in a screw cap 23 which closes the lower end of the cell. A tablet of potassium bromide 12 rests on a ledge in the casing and forms the electrolyte. Alternatively the tablet 12 may be placed in the water in the cap 23, and the fibrous layers surrounding the magnesium elements may extend downwards into the water, the cotton wool 20 being dispensed with. Fig. 5 shows in plan a modification in which eight magnesium rods 1 each surrounded by wood wool are arranged in a circle, the enclosed space containing a pad 25 of cotton wool. The second electrode consists of a single moulded porous carbon cylinder 26. The lower end of the pad 25 dips into electrolyte in the bottom of the cell as shown in Fig. 4 and air has access to the interior of the cell through the spaces 14. The electrode 26 is closed by a cover 28 which is held in position by tongues 30 projecting from a metal strip 31 surrounding the electrode. The ends of the strip 31 are flanged and provided with a terminal 32. The electrolyte consists of a solution of potassium bromide or iodide and may be fed directly to the lower ends of the wood wool layers surrounding the rods 1, the pad 25 being omitted. Instead of magnesium, alloys of magnesium with aluminium and manganese may be used for the positive electrode.
