Title: Improvements in or relating to cooling beds
Inventor: CLARK PATRICK ALWYNE
IPC: B21B43/10
Filed: 1963-02-14
Abstract: 1,020,369. Reciprocating conveyers. DAVEY & UNITED ENGINEERING CO. Ltd. Feb. 14. 1964 [Feb. 14, 1963], No. 6004/63. Heading B8A. [Also in Division B3] A method of controlling  the cooling of hot elongate bodies, such as rolled beams, comprises transferring the bodies successively to two cooling beds, the bodies being differently spaced on the two beds. Rolled bars from a roller table 11, Fig. 1, are moved by shifters 13 on to a cooling bed A, where they are traversed by walking beams 16. They are then transferred by shifters 17 to a second cooling bed B, again having walking beams 16, and are finally moved on to a runout table 20. Each shifter 13 (Fig. 5, not shown) is actuated by a rope wound round drums 25 and 26, the rope being attached to a slider plate housing a pivoted latch, the latch being extended during forward movement of the plate, in order to engage a beam to be moved, but being retracted during the return movement. The shifters 17 are similar to the shifters 13 but are each moved by a hydraulically actuated lever arm. Alternatively latches attached to the walking beams 16 may be used. The bars are traversed across the cooling beds by walking beams 16 (Fig. 4, not shown) which are first raised by pivoted hydraulically operated arms 50 to lift the bars clear of fixed supporting skids 15 and are then moved horizontally an appropriate distance by a piston operated arm 56 before being lowered again on to the skids 15. Each shifter 18 (Fig. 2, not shown) for moving a bar 68 on to the runout roller table 20 comprises a chair 21 slidably mounted on a frame 22 which is, in turn, slidably mounted on a track 23. The chair 21, which includes a substantially vertical surface 81 and a substantially horizontal surface 80 of adjustable length, is raised by a piston 34, operating through levers 29 and 28, to lift the track 23. Then a pulley mounted rope 24 traverses the chair to allow the bar to be deposited on the table 20. The bar 68 is first moved into position above the chair 21 by a latch 85 mounted on the frame 22, the latch engaging the bar as the frame is moved to the right. Any bending of a bar along its longitudinal axis is accommodated by each chair being slidable in its respective frame. The operating shafts connecting the transfer mechanism and the walking beams may be provided with disengageable couplings 26B.

Patent GB-384297-A (GB)
Title: Recovery of sulphur
IPC: C01B17/06
Filed: 1931-02-26
Abstract: In the recovery of sulphur by the treatment of iron sulphide material with a chlorinating agent, such as chlorine, sulphur chloride or sulphuryl chloride, the ore, which may also contain other sulphides, e.g. those of nickel and copper is treated with chlorine to vaporize sulphur and produce ferrous, nickel and copper chlorides which are treated with air to form ferric, nickel and copper oxides and chlorine, the ferric chloride being hydrolysed by steam to give hydrogen chloride which is oxidized by air to chlorine.  Dry, finely powdered ore is introduced at one end of a rotary reaction chamber, into the other end of which chlorine, either pure or diluted with inert gases, is passed.  The temperature may be maintained at 300 DEG to 350 DEG  C. throughout but, preferably, a temperature of 450 DEG C. is maintained near the charging end and 300 DEG  to 350 DEG  C. near the discharging end where the chlorine is introduced.  The residue is treated with air in a rotary reaction chamber to form ferric, nickel and copper oxides, vapours of ferric chloride and chlorine diluted with inert gases. The ferric chloride is condensed and treated with steam at 300 DEG  to 400 DEG  C., the resulting hydrogen chloride is dried by passage through a sulphuric acid tower and passed at a temperature of 520 DEG  to 530 DEG  C. over a catalyst consisting of the oxides produced from the chloride residue and carried on pumice contained in towers arranged in series, the gases being dried by sulphuric acid between each treatment.  The resultant chlorine is freed from hydrogen chloride by washing with water and is dried by sulphuric acid and returned to the process. The sulphuric acid used for drying is mixed with the washing water and concentrated, that part of the steam containing hydrogen chloride being used to treat the ferric chloride.  Nickel and copper chlorides formed in the catalytic mass are separated from the ferric oxide by washing. The chlorination operation may be arranged so that the ferrous chloride is separated from the other chlorides by allowing the temperature to increase from normal at the charging end to a maximum of 550 DEG  C. in the centre of the reaction chamber whence it decreases to 300 DEG  C. at the discharging end.  A gas outlet is provided where the temperature is about 450 DEG  C., ore being fed until a desired concentration is attained or until a predetermined amount has been supplied.  No chlorinating agent is supplied until the ore passes the point of maximum temperature after which the agent is admitted in increasing quantities.  Sulphur and ferrous chloride are first formed, the chloride passing to the discharge end where it is converted into ferric chloride which is vaporized and acts on fresh sulphide material to liberate sulphur and form ferrous chloride and is thus separated from the nickel and copper chlorides.  The ferrous chloride concentrate is treated with air at 700 DEG  to 800 DEG  C. to recover chlorine.

Abstract: 733,349. Electron beam apparatus. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. March 17, 1952 [March 23, 1951]. No. 6883/52. Addition to 721,227. Class 39 (1). The parent Specification describes a tube in which a hollow electron beam travels in the space between a central conductor 1, Fig. 1, and a tubular anode 3 under the influence of crossed magnetic and electric fields generated respectively by the current through the earthed conductor 1 and a positive voltage applied to anode 3; and is concerned with introducing the beam from a cathode 2 encircling conductor 1 so that it performs half a cycloid arch before entering the uniform space between 1 and 3 and travelling uniformly therein. In the present modification, the beam efficiency is increased by allowing the beam to perform several arches in a conical duct formed by extensions of conductors 1 and 3. In Fig. 1, anode 3 alone is conical and converging, while in other forms conductor 1 is also conical and converging or diverging; or conductor 1 alone is conical and converging. In the preferred form, the waves are conducted through the guide 10, Fig. 5, capacitive members 11, 12, matching tapered helix 14 to the helical delay line 13. The cathode 2 is connected to the heater leads 9 and thermal expansion is taken up by the bellows 16. A flexible leading-in wire 15 is connected to the electrode 3, which converges conically through matching section 14, while conductor 1 diverges conically. Ordinary travelling-wave amplification occurs, as in French Specification 985,536.
