Abstract: An optical Doppler velocimeter (10) is formed using erbium-doped fiber (82) as the lasing medium. By properly modulat-ing the lasing in the fiber, pulses of radiation are generated. Within the velocimeter, all optical signals are handled by optical fib-ers. A telescope (18) with a single optical fiber input/output interface acts as both the transmission device to focus the radiation at a specified point, and as the receiving system for collecting reflected radiation. The portion of the reflected radiation collected by the receiving system is analyzed to determine the Doppler shift caused by targets at the focal point of the telescope.

Abstract: A positive displacement pump and thrust bearing assembly having a housing defining an internal fluid chamber having front and rear inner walls. A rotor having a front face and a rear face is positioned in the fluid chamber. Each of the faces of the rotor is spaced apart from a corresponding inner wall of the fluid chamber to define predetermined clearances therebetween. A shaft is connected at a first end to the rotor to effect rotation thereof. A sealed container surrounds and encloses a second end of the shaft and is in fluid communication with the fluid chamber. The thrust bearing assembly is positioned within the container and includes an adjusting sleeve and an adjusting plate. The adjusting sleeve is attachable to the housing and includes a central bore through which the shaft extends. The adjusting plate is connectable to the shaft such that the sleeve is located between the housing and the adjusting plate. The adjusting plate is rotatable with the shaft and is in relative rotatable engagement with the stationary seat. The adjusting sleeve and the adjusting plate prevent movement of the shaft and the rotor in a direction away from the adjusting sleeve and toward the rear inner wall of the fluid chamber such that the predetermined clearances between the faces of the rotor and the internal walls of the housing are substantially uniformly maintained as the rotor rotates.

Abstract: A document imaging system includes means whereby a large number of anomalous condition indicators or flags that define anomalous conditions that may occur as a result of the operation of a document scanner and/or document processor. A computationally efficient subset of flags and flag combinations is defined, and these subsets of flags and flag combinations (system states) are related to a quantitative measure of the quality (degree of suspiciousness) of the related document images, the documents themselves, and units of work that contain a plurality of documents. The machine computation of quality is compared to a human perception of quality, and computational input parameters are adjusted to improve the match of computational quality to the human quality perception, thus teaching the machine to make proper determinations of image and document quality.

Abstract: In a method for integrity monitoring in position determination by means of the Global Positioning System (GPS), especially by means of differential GPS  (DGPS) or multi-station DGPS, wherein there is employed a monitor station (M) with a first GPS receiver, provided at a location with a known geographical position, GPS-based position measurement results are transferred on a communication line from the monitor station (M) to a user location (F) the integrity of whose geographical position has to be monitored by means of a second GPS receiver provided at the location (F). A space vector between the location of the monitor station (M) and the location (F) is determined by means of the position measurement results for the location (F) and the monitor station (M), whereupon the degree of agreement is determined between the position for the location (F), the space vector and the known position of the monitor station (M), the degree of agreement being required to correspond to a maximum error in the position for the user location (F).

Abstract: Apparatus for orienting elongate objects, for example capsules of medicament, comprises a passage for receiving an individual capsule in a preferred orientation, a container for holding a bulk supply of capsules, and a ramp surface which directs a capsule towards the passage when the device is positioned such that the passage extends vertically downwardly from the container. It has been found that by appropriate choice of ramp angle, passage diameter and container diameter there is a high probability that a single capsule will be loaded into the dispensing passage when the apparatus is inverted to place the dispensing passage below the bulk supply. The apparatus is particularly useful in a dry medicament dispensing apparatus comprising, in addition to the orienting apparatus, a chamber for receiving capsules from the dispensing passage, means for piercing the ends of the capsule, and a mouthpiece for drawing air through the capsule and to entrain the medicament.

Abstract: Relatively thin type 27 depressed center abrasive wheels are made from initially flat "green" wheels made in a hydraulic press that has flat upper and lower surfaces in each press cavity. These thin flat wheels are clamped in a fixture that forms the center portions as the wheels are clamped to provide "green" wheels that are not only thin, but that have depressed center portions of undistorted internal geometry. The "green" wheels are then cured in this clamped condition in a furnace at appropriate temperatures that achieve the necessary hardening of the resinous mixture to yield thin depressed center abrasive cutting wheels.

Abstract: An extrusion product or profile is formed by extrusion of a cellular compound to form a base and then subsequent extrusion of a non-cellular compound to form an attached flexible strip. The final product or profile is used as a garage door weatherstrip in which the cellular base is mounted against the door jamb and the strip of flexible non-cellular material extends out from the cellular base to prevent the flow of air through openings between doors and adjacent jambs or frames.      The process for forming such a product involves sequential extrusion of the two portions of the product.      First, a cellular base is extruded through a die and vacuum sizer and allowed to cool. Next, a saddle die is used to apply the flexible non-cellular strip to a portion of the cellular base.
