A photographic record 3 of an image of an object 1 is formed by exposing a photo-sensitive layer 3 to the image through a diffraction grating 4 in the form of a foil which is in contact with layer 3 and is stripped off the layer before processing. The diffraction grating may be a density or a phase grating. Desirably a plurality of images are recorded in superimposition, the foil then comprising an equivalent number of diffraction gratings of different grating constants and/or azimuthal angles. In a particular embodiment the image is coloured and the foil contains three gratings in super-position one for each of the primary colours. To reproduce an image or images from the record, the record is illuminated and at least one non-zero diffraction order is produced. Preferably a condenser 9 projects an image of a light-source 8 into a transform plane through a carrier 11 on which is the record. The diffraction orders are formed in the transform plane, and only select ones allowed to pass by a filter 10. The filter may be a plurality of colour filters or a diaphragm. The record may be a black and white negative and in reproduction the zero order is blocked to give a positive image.

The device may emit coherent or non-coherent light, and suitable semi-conductor materials are GaP, GaAs, GaAsP, GaAlAs, AlGaP, InGaAs and InGaP. The GaP device shown comprises an N-type substrate 11 on which are formed, by liquid phase epitaxy or diffusion, a Te-doped N-type layer 12 and a Zn and O-doped P-type layer 13. The device is bonded to a header by a Si-Au preform and a Be-Au electrode 15 is provided on the layer 13. The gallium oxide film 16 is formed, after etching and rinsing, by immersion in an aqueous H 2 O 2  solution. Oxide formation is enhanced by the presence of a noble metal catalyst, either in the solution or bonded to the semi-conductor, e.g. as one of the electrodes, and excess moisture is driven off by heating at progressively higher temperatures up to 150-350 C. An additional glassy layer 17 of SiO 2  improves the passivating properties of the gallium oxide film 16. The invention may also be applied to PNPN light-emitting devices. Boiling water may also be used as the oxidizing medium. Telephone and other uses are disclosed.

Ridge rollers 6, 7 and disc coulters 8, 9 are supported by the frame in front of the shares 10. In Fig. 2 any rise in the level of frame arm 18 or 19 causes a compensating linkage 27 to effect clockwise or anticlockwise pivoting of the frame about a longitudinal axis. The arms 18, 19 are pivoted about an axis 20 to intermediate lever arms 22, 23 which are pivoted to the chassis 2 at 24, 25 and to the linkage 27 at 30, 31. In one modification the arms 22, 23 are omitted and the linkage 27 is pivoted directly to the arms 18, 19 whose rear ends slide vertically in respective guide slots secured to the chassis. In another modification the frame 4 is a rectangle with its rear transverse bar mounted on a longitudinal pivot pin which extends from a further transverse bar mounted on the chassis. The pivot pin may also be connected to the frame so as to allow the arms 18, 19 to pivot vertically about a transverse axis as well as a longitudinal axis. Alternatively the transverse bar to which the pivot pin is attached may be rofatable about a horizontal axis. The screen conveyor 11 leads to a hoist conveyor, a separating conveyor and a collection bin.

Abstract: 1,114,723. Hydraulic couplings. J. BURKART. 15 Dec., 1966, No. 56160/66. Heading F2C. In an hydraulic coupling for a vehicle in which planet gears 330 operate with a sun gear 11 as gear-wheel pumps and in which the liquid, e.g. oil, flow around a closed circuit comprising axially extending suction chambers 34 and pressure chambers (35), Fig 2 (not shown), interconnected by pipes 44, 45 respectively, is throttled by a valve for torque transmission, the valve comprises: a cylinder having openings 450, 440 for entry and escape of circulating oil respectively; a sleeve 46 in the cylinder and having an aperture 465 in full continual registry with opening 450 and an aperture 464 movable into and out of registry with opening 440 to throttle the flow of oil to the suction chambers 34 by rotation of the sleeve controlled by a manually operated annulus 52 acting on a ring gear on the sleeve through integral pinions 520, 510; and a piston 47 in the sleeve and having an aperture 475 movable into and out of registry with opening 450 to throttle the flow of oil from the pressure chambers (35) by the oil pressure in the cylinder 41 and against a return spring 470 On turning the sleeve 46, aperture 464 is moved out of full registry with opening 440 and oil flow from the cylinder 41 to the suction pipes 44 is throttled, and since chambers 35 continue to admit a maximum amount of oil into the pressure pipes 45, the oil pressure in cylinder 41 rises, moving piston 47 against the spring 470 and moving aperture 475 out of full registry with opening 450 and aperture 465 to throttle the outflow of oil from the pipes 45. If, then, the transmitted torque is sufficient to turn the output shaft, the rotational speed of the planets 330 decreases, decreasing the pumping action thereof, and allowing the spring 470 to shift the piston back to move a larger area of aperture 475 into registry with the opening 450 to a position of equilibrium, preventing the transmission of excessive torque to the output shaft. As shown, the sun gear 11 is integral with the input shaft We, and the planets 330'are mounted in a carrier 30 integral with cylinder 41 and fast on the output shaft Wa. The carrier may alternatively drive the sun gear. An output- or input-driven pump 622 makes-up any leakage of oil from the closed circuit by feeding it through one-way valves 215 to the suction chambers 34. Bore 111 in the input shaft and sun gear 11 permits escape of air when the interior of carrier 30 is intially being pumped full of oil.
