Title: Improvements in or relating to the purification of minerals and salts
IPC: C01D3/14
Filed: 1923-12-07
Abstract: Crude salts or minerals containing argillaceous matter, calcium sulphate &c., are purified by washing with a saturated solution of the same salt, which removes the impurities in suspension.  The suspended impurities are separated from the solution, which is then ready for use again.  Rock salt and sylvine are mentioned as materials to be purified in this manner.  The purified material may be further treated by calcining at 300-600 DEG  C. to destroy the colloidal character of any remaining clay or the like so that it may be removed easily from a solution of the substance.

Title: Improvements relating to equipment for determining the distance of bodies by means of radio waves
IPC: G01S13/34
Filed: 1945-05-20
Abstract: 601,289. Radiolocation. COSSOR, Ltd., A. C., WILLIAMS, B. C. FLEMING-, and ALLEN, A. Nov. 20, 1945, No. 31257. [Class 40 (vii)] Radiolocation equipment for determining range comprises a transmitter whose frequency is varied linearly with time in each of a plurality of recurrent steps, the rate of change of frequency with time varying progressively from step to step over each cycle of the recurrence period of the plurality of steps and a receiver having means for deriving the difference frequency between the direct and object reflect rays, a circuit responsive to a narrow band of difference frequencies and means for indicating when the rate of change of frequency is such as to produce a difference frequency within said narrow band. A transmitter TX feeds a transmitting aerial TA, and echo signals from a distant object and also a portion of the signal direct from TA, are received on aerial RA and fed to receiver R. The output of TX is frequency modulated in saw-tooth fashion by unit TB1 so that at any instant there will be a difference frequency in receiver R depending on the difference between the direct " Ft " and echo reflected " Fr " signals. For a given rate of frequency variation of the saw-tooth modulation, this difference frequency is proportional to the distance to the object. A second saw-tooth unit TB2 generates a sawtooth wave of 50 cycle per second frequency and period P and this is used to scan cathoderay tube CRO and is also applied to TB1 to cause the rate of frequency variation, that is the slope of the saw-tooth modulation, to be uniformly decreased as shown at TB1 (Fig. 2) although for clearness this does not show the much greater frequency, for example 50 kc.p.s., of the TB1 modulation. During the sweep generated by TB2, the difference frequency, Ft-Fr=Fd, in the output of receiver R for a given object progressively decreases until at a given point in the sweep corresponding to the distance to the object it passes fixed tuned amplifier IF and intensity-modulates the cathode-ray tube to provide a spot GS at a distance D from the origin of the trace corresponding to the distance to the object. It is stated that the period of the saw-tooths generated by TB1 need not progressively increase as shown, but may be kept constant and the frequency variation decreased.

Title: Improvements in or relating to automatic reel winding or coiling machines
Inventor: BIGLAND BERNARD KEITH
IPC: B21C49/00
Filed: 1956-10-15
Abstract: 875,916. Sorting by gauging, measuring continuous lengths. GENERAL ENGINEERING CO. (RADCLIFFE) Ltd. Oct. 14, 1957 [Oct. 15, 1956], No. 31264/56. Class 106 (2). [Also in Groups IX and XXXVI] A long length of insulated wire or cable is tested and wound into a plurality of shorter lengths which are delivered into groups determined by the result of the testing, without interrupting the feeding of the wire to the winding apparatus at the completion of winding each shorter length. The insulated conductor is fed around fixed pulley 15 and movable pulley 13 slidable on track 14 which forms an accumulator and speed regulator. It then passes through testing devices 35 to 37, measuring diameter and concentricity, over pulleys 16a on traversing head 16 and on to one of the reels 40. Two automatically resetting counters 34 are set, the first to ten feet short of the required length and the second to the required length. As the conductor is fed to the apparatus the pulley 13 slides down the track 14, switching on a motor 11 and gradually increasing the speed of the reel 40 through a variable-speed gear 8. Spindles 1 carrying reels 40 can be driven or braked together or separately by selective engagement of clutch and brake units 2, mounted on shaft 3 which is driven from the gear 8 via belts 6 and 4 driving layshaft 5 and shaft 3 respectively. When the first reel is almost wound the first counter operates a switch to set a second reel 40 rotating by engaging the appropriate clutch 2 and the second counter operates mechanism to move the reversing head 16 over to feed on to the second reel 40 and also operates a knife 41 through a time delay to sever the conductor from the first reel after it has locked on the second reel. The movement of the knife also operates switches causing the first reel to be de-clutched and braked and air to be supplied to cylinder 26 to rotate the turret 25 thus swinging the first reel horizontally through 180 degrees to the unloading position (shown in chain line). A shoot 39 is provided at each loading position, one end 41 being hinged below the reel so that this end may either be pulled down or not by the operation of the cylinder 42 as determined by the testing equipment 35- 37, thus allowing the reel to roll forward or backward into one of two groups. The turret is then automatically rotated back through 90 degrees to the loading position (shown dotted in Fig. 2) and a fresh reel loaded either manually or automatically.

Patent GB-960701-A (GB)
Title: Production of ferro-nickel from oxidic nickel-iron ores
IPC: C22B23/02
Filed: 1960-09-12
Abstract: <PICT:0960701/C6-C7/1> The nickel content of a nickel-iron melt is increased by introducing oxygen into the melt only through the surface while agitating the bath by non-pneumatic means. Fluxing material such as silica is added and iron and impurities are oxidized and eliminated as slag; the melt may be enriched to a nickel content of at least 65% before nickel losses to the slag become excessive. The temperature of the melt may be controlled by varying the oxygen flow rate, cooling by addition of nickel-containing scrap, or supplying heat by burning a fuel gas in the oxygen stream.  As illustrated in Fig. 1, agitation is produced by carrying out the process in a rotary furnace 12 into which oxygen is blown through lance 15.  Slag is withdrawn by tilting the furnace, and metal tapped either by tilting or through taphole 19.  Slagging may be carried out in stages, later nickel-rich slags being returned to the smelting furnace.  The nickel-iron melt is advantageously prepared by selective reduction of nickel-iron ores by a gas mixture whereby all the nickel and some iron are reduced, the partially reduced ore then being smelted in an electric furnace. The reducing gases may be produced by partial combustion of oil, natural gas or coal, the ratio of CO:CO2 generally being in the range 3:2 to 1:3 by volume. Specifications 677,349, 789,258, 855,544 and 863,766 are referred to.

Abstract: 1,214,313. Automatic voltage control. MULLARD Ltd. June 18, 1968 [July 12, 1967], No.32017/67. Headings G3R and G3X. [Also in Divisions H1 and H2] A D.C. power supply (e.g. for the line time base in a television receiver) comprises an A. C. supply, half-wave rectified by a thyristor T1, the conduction angle of which is delayed by an R. C. network R7, C1 until a bi-directional semi-conductor breakdown device D1 breaks down, the charging of C1 being controlled by a shunt transistor T2 in dependence on the output voltage. As described, the A.C. supply A, B is rectified by thyristor T1 and smoothed by L1, R11, C3, C4. The conduction angle of T1 is arranged so that the output voltage is reduced to 150V; this is achieved by charging C1 during each half cycle until a diac D1 breaks down when thyristor T1 is triggered, and supplies power to the D.C. load. A feedback circuit via R5 ensures that the combined A. C. and D.C. bias on transistor T2 provides stabilization of the output voltage by variation of the charging time of C1. Zener diode D2 minimizes the temperature effect of transistor T2, A double -emitter transistor (see Division H1) may be employed instead of components T2 and D2.
