Abstract: The present invention relates to Compositions of fuels for transportation are disclosed, particularly organic compositions which are liquid at ambient conditions. More specifically, it relates to transportation fuels comprising suitable organic distillates, as a predominant component, and limited, but essential, amounts of a component comprising oxygen-containing organic materials, which materials are typically derived from natural petroleum. Beneficially, the oxygen content of these transportation fuels is at least 0.02 percent by weight. Preferably the oxygen content these transportation fuels is in a range from about 0.2 percent to about 10 percent by weight.

Abstract: A rotary slack adjuster (11) for use in a brake system of a vehicle (10) for compensating for wear in brake friction lining. The adjuster (11) includes an input arm (26) for connection to an actuating piston (25) of a brake actuator, an output arm (31) for connection to an output rod (24), and a rotatable member (49). Coupling device are provided for coupling the input arm (26), the output arm (31) and the rotatable member (49) together for mutual rotation during brake actuation in each of a first direction and a second opposite direction, while the rotatable member is confined to rotate between end limits in each of the first and second directions. The coupling device permits the input arm and the output arm to further mutually rotate in the first direction relative to rotatable member upon the rotatable member rotating to the end limit in the first direction.

Abstract: A system and method for dewatering a continuous stream of slurry at high flow rates demonstrates enhanced efficiency, economy and ease of operation. A stream of slurry is subject to continuous or continual measurement of flow rate and pulp density and the measurements are used to control the rate of addition of a flocculating agent to the slurry. The flocculated slurry is delivered to a dewatering unit where it is passed through a diffuser and evenly delivered to a tracking screen for filtering solids from a liquid filtrate. The pulp density of the filtrate may also be measured and used to control addition of a flocculating agent. The tracking screen is adjusted to achieve an angle of repose suited to the particular composition of the filter cake. The diffuser has a base having a horizontal section aspect ratio of from about 1:1 to about 4:1 and continuously changing vertically into an upper portion having a horizontal section with an aspect ratio of from about 40:1 to about 100:1.

Abstract: The present invention is directed to a continuous, portable dredging system that employs a series of screens and gravity separation devices with flocculation to remove sediments from the dredged slurry. The system produces a treated water stream having low solids content and a recovered solids product having a low water content.

Abstract: The apparatus and method of the present invention disclose a scanning imaging cytometer wherein an unprocessed biological fluid sample is reacted with a fluorescently-labeled binding agent. The reacted sample undergoes minimal processing before it is placed into a capillary tube. The sample is optically scanned and fluorescence excitation is recorded from a plurality of columnar regions of the capillary tube, each columnar region generally defined by the spot size of the excitation beam and the depth dimension of the capillary tube. A spatial filter of a sufficient pinhole diameter is selected to allow simultaneous volumetric detection of all fluorescent targets in each columnar region.

Abstract: A heater employs a ferromagnetic or like material heated by a varying magnetic field to heat the ferromagnetic material wherein the ferromagnetic material has a large cross-section comprised of many members of small cross-section insulated from one another and wherein for medical applications each member may be surrounded by a heat conductive electrically conductive coating.
