Inventor: MACKAY PATRICK W
IPC: C21B13/02
Filed: 1987-03-16
Abstract: A method and an apparatus for the gaseous reduction of particulate iron ores is disclosed, wherein the reduced ore, commonly called DRI (Direct Reduced Iron) or sponge iron, is treated in a vertical shaft moving bed furnace and discharged from said furnace in solid particulate form at high temperature, e.g. above 500°C. The shaft furnace is of the type wherein a bed of particles descends by gravity through said furnace which has an upper section where ore pellets, lumps, or the like are reduced by reaction with a hot reducing gas, and a lower section of a downwardly tapering, preferably, in a generally conical shape, which converges to an outlet discharge orifice of smaller cross sectional area than the rest of said furnace. A heat-exchanging means, optionally combined with insulation, in contact with the external surface of the wall of said lower section permits control of the temperature of said wall, whereby solids-flow problems in the furnace are minimized, producing a smooth operation and the desired hot exit temperature of the discharged DRI all in a reactor of a practical foreshortened size.

Abstract: The present invention relates to a distal femoral surface shaping guide for mounting on an intramedullary alignment guide which references the central long axis of the femur in shaping the distal femoral surface and a method for shaping the distal femur using that shaping guide. The alignment guide of the present invention is adjustable relative to the surface of the anterior femoral cortex to insure that the anterior aspect of the distal femoral condyles is resected relative to that surface and, preferably, at the same level as that surface. The alignment guide of the present invention provides a main body which remains attached to the intramedullary alignment guide throughout the entire shaping of the distal femur. It thus requires fewer cutting guides and alignment steps than other shaping guides while allowing greater accuracy in shaping the distal femur relative to the central long axis of the femur.

Abstract: A known form of printing machine for printing alphanumeric characters and symbols on an elongate tape utilises a circular font or "typedisc". The known tydedisc is a one-­piece moulding which makes even a minor alteration in the character set expensive to achieve. In order to maximise the use of common components while avoiding the difficulties associated with individually replaceable characters, selected sub-sets of characters, symbols or patterns are mounted or formed on the periphery of a part-circular segment 3. A suitable number of segments 3 are detachably secured to a common hub 2 by mount ng means (5-9, 16a, 16b). The sub-sets of characters can be formed separately and attached to a common segment component (Figs 8-10), or formed directly on otherwise identical basic segments (Figs 11-15). Segments are readily interchangeable, and a multiplicity of typediscs can be formed from a minimum number of components (2,3, 5) which differ only in the readily formed and individualised characters (41;42) that they carry.

Abstract: The invention is generally directed to a video apparatus for storing video images on a recording medium and replaying the stored images on a display. A camera mechanism converts light images into electrical video signals. A processor circuitry (200) coupled to the camera mechanism includes means for converting the electronic video signals into a low bandwidth frequency modulated storage signal with the bandwidth substantially lower than in a standard television video signal. A recording mechanism (240) coupled to the processing means stores the low bandwidth frequency modulated storage signal on an audio cassette, which has a standard speed allowing storage of an audio bandwidth signal. The recording mechanism includes a drive mechanism for driving the audio cassette at higher than normal speed to increase the bandwidth storage capacity of the audio cassette. A recording head mechanism stores the low bandwidth frequency modulated storage signal on the audio cassette. The video apparatus also includes a switch mechanism (220) for switching the video apparatus from a record mode where video images are stored on an audio cassette to a playback mode where the stored images are read off the audio cassette and displayed on the video display. In playback mode, the low bandwidth video signal is converted to a higher frequency standard television bandwidth video signal for display. The rate conversion from a low bandwidth video signal to a standard television video signal is performed by a "ping-pong" digital memory system. The video apparatus also adjusts the sensitivity of the camera mechanism by adjusting the exposure time of the camera mechanism based on the incident light.

Abstract: A method and system for removing hydrogen sulfide from a hot gas. In a moving bed absorber, sulfur compounds in the hot gas moving in a direction which is countercurrent to the direciton of movement of the movable bed of metal oxide, react with metal oxide to form metal sulfide. The metal sulfide is regenerated to re-usable metal oxide in a moving bed regenerator. The regeneration is carried out with an oxygen-containing gas in which regenerator off-gas serves as a diluent to control oxygen concentration. In the regenerator, spent metal sulfide moves progressively through a single regeneration vessel having first, second and third regeneration stages. In the first and second regeneration stages, first and second oxygen and sulfur dioxide-containing gases move, respectively, in a direction which is cocurrent with the direction of movement of a movable bed of spent metal sulfide. In the third regeneration stage, an oxygen-containing gas moves in a direction which is countercurrent to the direction of movement of the movable bed of metal sulfide from the second regeneration stage. The combined gases derived from the first, second and third regeneration stages and which are rich in sulfur dioxide and lean in oxygen, are removed from the regenerator as off-gas and used as diluent with air, oxygen-enriched air or pure oxygen to provide the low oxygen concentration in the oxygen-containing gas introduced into the first and second regeneration stages.

Abstract: @ A three-dimensional vision seam tracking method and apparatus for controlling the motion of the center point of a tool mounted on a manipulator. The manipulator is provided with a control to operate the manipulator members to move the tool center point at programmed velocities along a programmed path corresponding to the seam. The manipulator is provided with a vision system including a laser scanner/camera head mounted ahead of the function element. The control is programmed with dynamically varying orientation angles to control the orientation of the tool during seam tracking. The laser scanner/camera head scans the seam at predetermined time intervals. A set of coordinates for the center point of the seam in a coordinate system relative to the camera is provided for each scan. The sets of camera coordinates are transformed to the coordinate system of the manipulator using transformation matrices employing the orienation angles in effect at the time of the scan for the set of camera coordinates being transformed. The transformed coordinates are stored in a FIFO buffer until needed. The seam tracking routine of the manipulator control removes FIFO entries at some later time and alters the manipulator's programmed path to move the tool center point along the seam.
