Abstract: 288,882. Television, Ltd., and Baird, J. L. Oct. 15, 1926. Divided on 289,104. Television.-Apparatus of the kind used in television is adapted for producing a visible image of an invisible object irradiated with ultra-violet or infra-red radiation. Thus in the arrangement shown in Fig. 2, an object 21 (which may be a physical object, or the projected image of a distant object irradiated by a source 19 infra-red radiation. In order to facilitate amplifivided with a thin ebonite screen) is analysed by means of a rotating disc carrying spirally arranged lenses 22, the picture elements falling succesively on a bolometer or other detector 23 sensitive to infra-red radiation. In order to facilitate amplification the infra-red beam is rhythmically interrupted, before or after reflection from the object by a slotted disc 14, and the electrical output of the detector 23 is amplified at 24 and made to .control the illumination of a lamp 25. The picture is then synthetized by a rotating lens spiral 26, a visible image being formed at 27. In modifications a single disc may carry the two lens spirals 22, 26, the object 21 and lamp 25 being on one side of the disc, the detector 23 and visible image 27 on the other. In this case one spiral may be of smaller radius than the other and mav lie concentrically within it, or two similar hall-spirals may be arranged opposite to one another, as at 44, 45, Fig. 5, each serving for analysis and synthesis in turn. In the arrangement shown in Fig. 5, an object 40 is irradiated through the rotating lens spirals 44, 45 by a beam from an infra-red source 50, radiation from the object being reflected by a concave mirror 51 on to a detector 52.

Abstract: 405,258. Intercepting-valves for compound &c. engines. SENTINEL WAGGON WORKS, Ltd., 20, Iddesleigh House, Caxton Street, London, and DOBLE, A., The White House, Ellesmere Road, Shrewsbury. July 30, 1932, No. 21547. [Class 122 (iii).] A compound or multiple-expansion engine is provided with an intercepting-valve casing containing a differential valve for supplying steam to the low-pressure valve-chest, and a piston-operated valve for putting the highpressure cylinder exhaust into communication with the low-pressure cylinder or the atmosphere or condenser. The dimensions of the pressure areas of the supply valve are such that the low-pressure and high-pressure piston thrusts are equal under various conditions of working. The valve-casing comprises two parts 12, 14 bolted to a transverse wall 16. The part 12 forms two chambers 18, 19 in which work the parts 22, 24 of a differential piston, the third part of the piston 26 working in a bore 27 in the wall 16. The part 22 has a seat 62 which controls a supply of steam through a passage 60 to a passage 42 connected to the left-hand end of the cylinder 30 housing the piston 40 of the intercepting-valve 36. The passage 42 is connected by a duct 45 to the lefthand side of the chamber 18. The right-hand end of chamber 18 is connected to the atmosphere or to a condenser. The valve 36 controls the high-pressure exhaust connection 34 to the atmosphere or to a condenser through a passage 32 and to an outlet 41 leading to the lowpressure cylinder. The right-hand end of the cylinder 30 may be connected to the outlet 41 by means of a passage 56 for running compound, or to the atmosphere or a condenser by means of a passage 58 for running simple. The connections are controlled by a hand-operated twoway valve 54. The areas of the faces 78, 80 are such that at a certain low-pressure receiver pressure the supply from pipe 60 is cut-off. When the engine operates as a simple engine, the valve 22 will open at each stroke during the period of admitting main steam to the lowpressure cylinder.

The iron bearing substance may be produced by hydrolysis of iron chloride, or may be a calcine produced by the oxidative roasting of an iron bearing sulphidic material or may be ferrous hydroxide produced by the addition of ammonium hydroxide to iron values contained in the aqueous acidic solution. The iron bearing substance may be present in an amount such as to react with substantially all free acid in the aqueous solution and the acid generated during precipitation of the non-ferrous metals which may take place at a temperature between 50 C. and the boiling point of the solution. The aqueous acidic solution may be a solution obtained by the leaching of iron and nickel bearing sulphidic materials using hydrochloric acid which after treatment by the process of the invention may provide almost pure ferrous chloride solution suitable for the regeneration of hydrochloric acid which may be used in the leaching of the sulphidic material and pure iron oxide which may be used in the process of the invention.
