Title: Improvements in processes of treating iron ores
IPC: C22B1/08
Filed: 1928-05-17
Abstract: 306,107. Camstock & Wescott, Inc., (Assignees of Wescott, E. W.). Feb. 16, 1929, [Convention date]. Drawings to Specification. Grant of Patent opposed. Sulphur. - Iron ores, particularly sulphide ores, axe chlorinated in a split cycle process at about 375‹ C. tu give ferrous chloride, diluent gases being removed from the system, and then this is further chlorinated by means of chlorine to give ferric chloride, which is then burnt with hot air at 700-800‹ C. to give ferric oxide and chlorine, without intermediate condensation of the ferric chloride. A small amount of producer gas may be added to act catalytically to coarsen the oxide produced. The recovered chlorine is then divided, two-thirds being used to chlorinate further quantities of ore. In the case of sulphide ores, it is passed through molten sulphur to form sulphur chloride which is then used as the chlorinating agent. The remaining one third is used to chlorinate the ferrous chloride to ferric chloride, thus giving a cyclic process. The sulphur obtained from the sulphide ores is condensed and recovered, part being used to regenerate sulphur chloride. In the case of oxide ores, the chlorinating agent used in both stages is chlorine. The ore is preferably crushed to about 80-100 mesh,the time of reaction de. creasing with the fineness of the ore. Very fine material may be treated by feeding the ore as a cloud or spray against upward flowing reacting gases. In the case of resting charges, the presence of coarse and fine material deads to resistance and slowness of reaction, hence the crushed material is preferably graded and each grade separately treated or layers of sized ore may be formed for a single charge. The addition of coarse sand also increases the permeability in the case of very fine material or if the ore is very rich or pure. Specifications 255,639 and 321,911 are referred to.

Title: Mechanical television scanner
IPC: H04N3/08
Filed: 1968-03-26
Abstract: 1,216,396. Television. TECHNICAL OPERATIONS Inc. 26 March, 1968, No. 14586/68. Heading H4F. An optical scanning system comprises a train of co-operating reflector pairs arranged at a converging angle in the direction of an input light beam, means for moving the mirror train in a path transversely to the light beam, optical means for focusing the beam substantially in said path and lens means for producing a repetitive one-dimensional spot scan in response to the movement of the reflections. In a known arrangement a horizontal scan of a moving film 14, Figs. 1 and 2, is produced by a rotatable multi-face mirror drum 10 and a lens system 12 through which a beam of light is focused, the vertical scan being provided by the movement of the film. The drum 10 has 32 reflecting surfaces consisting of eight on each of four separate elements all secured to a shaft 16 rotatable by a motor. The reflecting surfaces are offset 11 degrees 15 minutes from each other to divide the full circle into 32 equal angles of reflection, the various faces one at a time reflecting the incoming beam 15 to a scanning sweep via the lens 12 across the sensitized surface of the film 14. If the light source 15 is split into two paths, Figs. 7, 8 (not shown), the drum 10 may consist of two parts each carrying eight reflecting surfaces. In the present invention, to enable an image to be projected on a screen 14, the vertical scan is provided by a circle of prisms 20, Fig. 3, which are right-angle reflectors, Fig. 4, mounted on a disc 24 on a rotatable shaft 25. Light from a source, not shown, passes via a modulator 18 and lens 19 to the reflectors 20 and thence via a collimating lens 22 to the device shown in Fig. 1. The operation is improved by tilting the disc 24 as shown. In a modification, Fig. 6 (not shown) two parallel input light beams representing "interlaced" signals are provided and the reflectors 20 are masked so that the beams are reflected alternately. In a further embodiment, Fig. 11, collimated light such as a beam 110 from a laser 112 is focused at 114 into a converging beam 116 co-operating with right-angular reflector pairs 18 on a rotatable shaft 120, which operate in a similar manner to reflectors 20 of Fig. 3, to produce a horizontal scan. The reflected beam 130 is passed via a lens 132 to a mirror 134 and reflected via the lens 132 and mirror 138 to a further group of right-angular mirror pairs 122 on a rotatable shaft 126 driven through reduction gears from the shaft 120 to produce the vertical scan. The beam 140 from the mirrors 122 is reflected by the mirror 138 and via lens 133, mirror 142, lens 133 and mirror 138 is directed to a focal point on a screen or film 146.

Title: Improvements in or relating to radio telegraph systems
IPC: H04L1/06
Filed: 1940-09-28
Abstract: 545,126. Wireless receiving systems. STANDARD TELEPHONES & CABLES, Ltd., and EARP, C. W. Sept. 28, 1940, No. 14673. [Class 40 (v)] In a radio telegraph system in which signals are radiated by intermittent interruption of a radio-frequency wave modulated by a low frequency tone, the receiving apparatus is arranged that it takes up the same predetermined condition when the transmission is disturbed whether by interference or by fading. Fig. 1 shows an arrangement which is a modification of the arrangement described in detail in Specification 540,839. The output from the second frequency changer D2 is fed through three low pass filters F, F<SP>1</SP>, F<SP>11</SP> to supply signalling paths SP, SP<SP>1</SP>, SP<SP>11</SP> feeding into a conversion circuit CC to which is also fed over an interference path IP an interference component taken through filters F1, F2, amplifier A3 and detector D3. The conversion circuit CC feeds a telegraphic relay circuit RC, security apparatus SA and recording apparatus such as a teleprinter TP. The conversion circuit comprises valves V3, V4, Fig. 2, arranged as explained in Specification 540,839 so that a signal marking impulse at input terminals 1, 2 causes anode of V4 to become more negative while an interference pulse at 3, 4 causes the anode of V4 to become more positive. Thus the effect of interference is the same as fading or as a spacing impulse and a false " mark is impossible. The rectified voltage at the grid of V3 corresponds to the strongest of the signals applied through rectifiers RS, RS<SP>1</SP>, RS<SP>11</SP> since the voltage set up across R7 passes the rectifiers so that the smaller signals are not operative. In a modification, Fig. 3 not shown, valve V3 is dispensed with by reversing rectifier R1 and feeding the voltages from the signal and interference paths in opposition to the grid of V4. In another modification a separate valve V3 is provided for each signal path, the strongest output being fed to V4. In a final modification each signal path has a corresponding interference path.

Abstract: 724,221. Foundry plant. COMBUSTION ENGINEERING-SUPERHEATER, Inc. June 11, 1952 [June 20, 1951], No. 14704/52. Addition to 704,815. Class 83 (1). Foundry plant according to the parent Specification is provided with automatic means for removing the copes from the poured moulds which comprises means over a portion of the track to engage the cope of each mould which passes on its truck and, as this travels downwardly, gradually separates the cope from the drag which remains on its truck. The track 32 is extended to form a reverse loop Q so arranged that a mould first passes under a part of the track at P, then moves up an incline until at T the bars 28 of the cope pass over pairs of wheels 366, Fig. 9, arranged on supports 364 inclined down but less steeply than the incline of the track 32 which, between T and U, is vertically below the supports 364. Projections 368 or other means on each truck prevent the drags from being pushed off the trucks and they continue to travel thereon to the place where the castings are removed. The copes after separation run down to the shake-out 47 and are dealt with as in the parent Specification. A switch is arranged at K so that if a cope lifts its drag, e.g. if the clamps have not been removed, the drag will operate the switch and cause the motor driving the train of trucks to stop. A mouldcounting device including a photo-electric cell may be arranged at 372. The loop Q is preferably long enough to allow adequate cooling. Specification 724,238 is referred to.

IPC: F16D65/58
Filed: 1932-05-25
Abstract: 397,984. Adjusting brakes. RAILTON, R. A., Brooklands Track, Byfleet, Surrey. May 25, 1932, No. 14796. [Class 103 (i).] Movement of an automatically adjustable stop for determining the clearance between a brake shoe or other brake member and the rotating drum or other coacting brake member in a hydraulically applied brake is freely permitted in the direction for reducing the clearance and is resisted in the opposite direction as by a coil-clutch member disposed between the stop and a fixed member, the arrangement being such that the clearance can be increased when desired by means accessible from the outside of the anchor plate of the brake. The brake shown comprises a pair of brake shoes 12 pivoted at one end on a fixed plate 11 and connected at the other end to a hydraulic cylinder which applies them to a drum 9. The stop device comprises a pin 32 on the shoe 12 engaging with clearance the forked part 31 of a cap 26 rotatable on a socket 23 fixed to the plate 11. One end 34 of a coil clutch spring 33 passes through a hole in the cap 26 and the other end through an arcuate slot 36 in the socket 23. If in applying the brake the movement of the shoe 12 exceeds the clearance allowed by the fork 31 the cap 26 with the spring is freely rotated but reverse movement of the cap and spring when the shoe is disengaged from the drum is prevented by the binding action of the spring against the socket. The clearance of the shoe can be increased when desired by turning the spring by its other end 35.
