Title: Improvements in or relating to optical apparatus
IPC: G01J1/22
Filed: 1950-01-25
Abstract: 748,481. Photo - electric light chopper. OPTICA SOC. PER AZIONI. Jan. 25, 1950 [Oct. 5, 1949], No. 1909/50. Class 40 (3). [Also in Group XX] Optical apparatus comprises a single circular disc which is rotatable in a plane inclined to an incident light beam about an axis passing normally through its centre, this disc being adapted, as it rotates, to direct the beam alternately along different paths, each of which contains means for re-directing the beam to the same destination where a lightactuated device (e.g. a photo-electric cell) is situated. As shown in Fig. 5, a light beam A strikes the inclined disc 1 and, as the disc rotates, is either reflected at right angles in the direction b by a specular section of the disc or transmitted through a diametrically opposite transparent section of the disc along a path c. The beam b is subsequently directed by a mirror 4 through a partial reflector 6 and the beam c is directed by mirror 5 onto the partial reflector 6 and is reflected by the latter so that beams band c travel along the same path d at different times to a photo-electric cell. In another form the transparent sectors of the disc may alternate with the specularly reflecting areas of the disc, or specularly reflecting areas may alone be provided, the reflecting surfaces thereof being differently inclined to the surface of the disc. The partial reflector 6 may be omitted and the beam c caused to converge on beam b by a plain mirror. Specifications 14754/02 (Class 97] and 298,024 [Class 69 (ii)] are referred to.

Title: Process for gasification of solid carbonaceous fuels
Inventor: GALOCSY ZSIGMOND DE
IPC: C10J3/08
Filed: 1962-01-18
Abstract: A process for gasifying a solid carbonaceous fuel, e.g. coal or coke, in a slagging producer comprises preheating the gasification agent to at least 1000 DEG  C. in a heat exchanger.  The agent is oxygen (or oxygen-enriched air) in excess, and steam and/or carbon dioxide.  The agent may be heated by the method described in Specification 772,837. The fuel, e.g. pulverized coal, which may be supplemented by gas from a zone of the producer at 1000 DEG  C., may be blown into a stream of the heated gasification agent.  Slag formers, e.g. metallic ores, may be introduced into the producer, e.g. at the top or via the gasification agent, to provide oxygen for combustion, and iron powder may be introduced.  Hydrogen and carbon black may be produced by introducing liquid or gaseous hydrocarbons, which may be preheated into the producer for cracking, and activators, e.g. ZnCl2 or alkali metal salts, may be introduced via the gasification agent to accelerate the reactions.

Title: Improvements in or relating to overspeed and overwinding gears for winding engines
IPC: B66B5/08
Filed: 1925-01-22
Abstract: 249,261. General Electric Co., Ltd., and Whitmore, F. L. Jan. 22. 1925. Overwinding, preventing.-Relates to a safety device applicable to the type of gear for preventing over-winding described, for example, in Specifications 29424/04 and 7664/08. In this gear nuts D, E<1> travel on a revolving screwed shaft A so as to follow the movements of the cage, the nut D acting at the limit of its upward movement to release trip-gear, part of which is shown at J<1>, K<1> to cut off the power and apply the brakes, and the nut E<1> co-operating with governor-actuated mechanism O to check excessive speed as the cage approaches the pit-bank. The safety device comprises a sleeve B which can slide upon a feather on the shaft A, and is connected to a lever E so as to move upwards by gravity at a speed determined by a cataract piston in the chamber H, this speed decreasing as the sleeve is raised towards the top of its stroke. The sleeve B is normally held in its lowest position by a spring L acting through a lever J provided with an eye which slides over the link K. As the nut D approaches the top of the shaft A, it engages and raises the lever J. The sleeve B is then free to rise under the control of the cataract until it abuts against the collar C, when the gear will act in the normal way to stop the cage if it passes beyond the bank level. If, however, the speed of the cage exceeds a predetermined value, the nut D overtakes the sleeve B and then turns with the shaft A and stops the cage. When the cage is next lowered, the safety device returns automatically to the original position.

Abstract: 471,843. Centrifugal gas - cleaners. NAAMLOOZE VENNOOTSCHAP MACHINEFABRIEK JAFFA VOORHEEN L. SMULDERS & CO. Jan. 23, 1937, No. 2046. Convention date, Feb. 24, 1936. [Class 23] Gas is freed from dust and other particles during its passage inwards through apertures in a rotating drum 1, the arrangement being such that the apertures are closed by flaps or blades 4 when the speed of rotation drops to approach a value at which the particles reach the circumference of the drum. The drum rotates in a casing 2 to which the gas is admitted by the entry 3, and the clean gas is drawn from the interior of the drum by the exhauster 43. The spindles 6 of the blades 4 are mounted in rings 8 at the end of the drum, and levers 9 attached to the ring 12 are clamped to the spindles 6. The ring 12 carries a number of brackets 13, each being held by a spring 14 against a fixed stop 16. When the machine is running normally the brackets 13 move against the springs 14 and the blades 4 open the drum apertures, but if the speed drops sufficiently the springs 14 move the brackets 13 and the ring 12, so that the blades close the apertures to prevent dust from passing into the drum. The arrangement permits the drum to run by a free wheel connection after a brake has been applied to the exhauster.

Title: Method of preparing a simulated ground contour transparency
IPC: G09B9/40
Filed: 1960-01-21
Abstract: 916,430. Photographic maps. ACF INDUSTRIES Inc. Jan. 21, 1960 [April 7, 1959] No. 2212/60. Classes 97 (1) and 98 (2). Relates to photographic methods of preparing a transparent or opaque map of an area of the earth's surface such that the optical density at any point on the map is proportional to the height of the corresponding point on the earth's surface. In one embodiment, Fig. 1, radiation such as light, X-rays, neutrons or gamma rays is projected from a source 112 on to a photographic plate 110 through a solid three-dimensional model of the area of the earth's surface formed of material whose radiation absorption is proportional to its thickness, e.g. plaster or lead for light of X-rays, respectively. In another embodiment, Fig. 2, the model 8 is painted white and placed in a tank 160 under a camera 161 and when the camera shutter is opened to make a time exposure a dark opaque fluid, e.g. ink, is allowed to flow from a tank 164 through a valve 165 into the tank 160 so that the lower parts of the model are covered before the higher parts and hence the exposure time of any print on the model is proportional to its height; alternatively a dark-coloured model and a light-coloured fluid may be used. Small apertures are formed in the model at the lowest point in any depressions which have no natural drainage paths to the sea level datum plane and the camera shutter and valve 165 may be controlled electrically. In a modification the model comprises cheese cloth or like material formed to the shape of the earth's surface so that the fluid will rise uniformly throughout. The completed map may be scanned photoelectrically to produce a voltage proportional to surface height as described in Specification 916,431, or the height may be read off a calibrated light meter held over the map.

Filed: 1928-01-24
Abstract: 314,100. Link, R. P. Jan. 24, 1928. Holders for loose types; embossing.-In a printing or embossing forme, particularly for use in " cutter-crush " machines, comprising bars for supporting the type or dies, the the bars or the type are formed with shoulders to provide ribs of less thickness than the bars to engage in slots in the type or the bars, the width of the slots being greater than the thickness of the ribs to permit of a limited movement of the type transversely to the ribs. As shown, bars 25, Fig. 2, are formed with ribs 29 to engage in slots in opposite edges of the type or dies 27. Clips may be provided to prevent endwise movement of the types on the bars, the clips consisting of split tubular members 32<a>, Fig. 10, a plate 30<a>, Fig. 9, with split and bentout ends 30b to grip the ribs 29 of a pair of adjacent bars 25, or a bar 30, Fig. 7, with shaped ends 31 to engage one side of the bars 25, and a spring 32 to engage the opposite face of the bars. The forme may be combined with a platen 10 on which the sheets or cards to be printed or embossed may be supported. For this purpose, the bars 25 are provided with hooks 26, Figs, 2 and 3, to engage bars 24 carried in brackets 21 secured to or integral with saddle bars 12 embracing flanges on the sides of the platen 10. The bars 12 have slots 14 engaging pins or screws 13 on the flanges to allow movement of the bars to and from the platen to facilitate the insertion of the sheets or cards. This movement is effected by bars 15 connected by a handle 19 and sliding between the bars 12 and flanges, the bars 15 having inclined slots 18 engaging the pins 13 and straight slots 17 engaging pins or screws 16 carried by the bars 12. The bars 24 are preferably of rectangular section and have grooves 24<a> to engage the sides of the brackets 21. The grooves in different faces of the bars 24 are of different depths so that by turning different faces of the bars towards the platen, the type faces may be held a little above the platen to provide space for the sheets or cards, or if the types are inserted face upwards and the sheets or cards laid upon them, the backs of the types may be allowed to rest on the platen. In a modification, the type bars 25 are arranged parallel to the bars 24, the ends of the bars 25 being clamped to cross bars secured to the bars 24.
