Abstract: A correction to the output angle of a ring laser gyroscope (10) is calculated as a function of the phase difference and the magnitude of coupling between the two counterpropagating beams when the dither oscillations change direction. A pair of heterodyne detectors (50A, 508) produce heterodyne signals indicative of the interference pattern between the counterpropagating beams. A signal indicative of the sum of the separate beam intensities is demodulated (92) with the heterodyne signals to determine the magnitude of coupling between the beams in the ring laser gyroscope (10).

Abstract: A device for releaseably holding a workpiece includes a resilient collet which is pivotally attached to a base. Several fingers for holding the workpiece extend from the collet. The fingers are pivoted by actuating a member which elastically deforms the collet and causes the fingers to pivot from a position for engaging the workpiece to a position for releasing the workpiece and vice-versa. In one application, the base is a platen for supporting a wafer in a semiconductor processing system and a plurality of such platens and a corre­sponding plurality of the holding devices are arranged around the periphery of the disk. A counter­weight ring is attached to the ring-shaped collet to counter-balance the moment generated by the centri­fugal force of the wafer pressing against the fingers as the disk is rotated.

Abstract: An optical fiber (21) which has been drawn from a preform (22) is moved into and through a chamber (38) of a housing. A source of vacuum is connected to the chamber to prevent the attachment of air pockets to the optical fiber as it is being moved through the chamber and through an opening of a die. The die includes a flow path (55) which is substantially normal to the path of travel of the optical fiber and the die opening is substantially larger than the diameter of the optical fiber. The thickness of the flow path in a direction along the path of travel is sufficiently small so as to prevent the recirculation of the coating material in the vicinity of the point to application to the optical fiber. Also, the fiber draw rate, the pressure of the coating material the direction of the flow path relative to the longitudinal axis of the optical fiber and the diameter of the die opening are such that a gap forms between the coating material and the die. That gap is allowed to be maintained because of the pressure differential between ambient atmosphere and the chamber. As a result, the coating material as it leaves the disc-like flow path and is directed toward the optical fiber is bounded by free surfaces instead of by soild surfaces in the immediate vicinity of where it is applied to the optical fiber. This prevents the development of shear fields and allows the diameter of the coated optical fiber to be varied.

Abstract: A line segment is created by activating a series of linear elements (R, G, B) substantially centered about the desired line segment position and providing for various intensities for each element. The notion of a pixel group is completely discarded and each individual display element (R, G, B) is individually addressed and individually assigned an intensity depending upon the desired line segment to be displayed and the orientation of that line segment. The method comprises generating element intensity, position and line slope information for a given line segment; inverting and registering the element intensity information; centering an array of elements around the element position information; determing the color of elements in the array of elements; determinining the proper intensity for each element in the array of elements in order to produce the desired position of the line; and providing the proper intensity for each element and the array of elements in order to provide the proper line color.

Abstract: In fluidised-bed combustion apparatuses with stationary fluidised-bed, secondary air is blow into the free space (10) above the fluidised-bed (6), in order to burn out the combustible substances which are still contained in the rising gas. In this connection, the homogeneous mixing in of the secondary air and the maintenance of a minimum temperature in the free space (10) are important. Upwardly directed secondary air nozzles (14) are pointed, in the manner of injectors, into pipe sections (13) which are arranged vertically, distributed over the area of the fluidised-bed (6) and open at the top and at the bottom, and which are immersed with their lower ends in the fluidised-bed (6) and project with their upper ends into the free space (10). By an injector effect, hot granular material is drawn along by the secondary air from the fluidised-bed (6) and thrown into the free space (10). As a result, heat is supplied to the free space (10). Moreover, the mixing in of the secondary air into the gas rising from the fluidised-bed (6) is improved. <IMAGE>

Abstract: This invention relates to an assay for fibrin polymers for use in the diagnosis of patients at risk of thrombosis and in monitoring the effects of treatment in such patients. More particularly, the present invention relates to an assay for soluble crosslinked fibrin polymers in patient samples involving the  in vitro  treatment of the sample wit a proteolytic enzyme such as t-PA which generates the D-dimer fragment of soluble fibrin polymers. The amount of D-dimer formed is determined, preferably, by an immunoassay specific for D-dimer. The measurement of D-dimer is thus a useful reflection of the hypercoagulability state and the test may be useful for assessing pre-thrombotic or thrombotic disorders such as myocardial infarction, pulmonary embolism and deep vein thrombosis, as well as for soluble fibrin formation in neoplastic, immune, inflammatory states, or other pathologic conditions, and for evaluations of therapy such as with anticoagulants that are used to treat these conditions.
