Abstract: SPOOL FOR HOLDING OPTICAL FIBER     Abstract A spool which is used in the taking up and the paying out of a relatively long length of optical fiber includes two flanges and a hub with each flange being tapered. The spool includes a collector which is formed adjacent to one of the two tapered flanges of the spool and which provides access to the initial or leading end portion of the length of optical fiber which is wound on the spool. A groove of the collector communicates with the hub of the spool through each of two diametrically opposed slots in the adjacent tapered flange. This allows the optical fiber to be wound on one of two coaxially mounted spools and to be transferred to the other spool with the first few convolutions being received in the groove and then passed through one of the slots in the adjacent tapered flange onto the hub. In order to prevent losses in the optical fiber portion which extends through one of the slots, each slot is sufficiently wide to avoid unduly sharp curvature of the optical fiber portion. The spool with outwardly sloped flanges provides for a stable winding pattern which prevent snags in pay out operations. The capacity of this spool with a stable winding pattern may be maximized by optimizing the slope of the tapered flanges.

Filed: 1988-05-26
Granted: 1992-02-04
Abstract: Abstract Superabsorbent articles in the form of soft, nonwoven fibrous webs are produced from aqueous,fiber-forming polymer solutions by forming the polymer into water soluble filaments, contacting the filaments with a primary air stream having a velocity effective to attenuate and to partially dry the filaments, contact-ing the attenuated filaments with a secondary air stream having a velocity effective to fragment the filaments into fibers and to transport the fibers to a web-forming zone while also further attenuating and drying the fibers, collecting the fibers in reticulated web-form in the web-forming zone and curing the web to a water insoluble state. The temperature and air stream velocities are controlled with respect to am-bient humidity and water content of the fiber during the fiber and web formation such that the fibers are collected without sticking. Collection is preferably on a wire belt followed by transport through a curing oven to compacting rolls and web take-up.

Abstract: Abstract of the Disclosure The methods disclosed herein incorporate the basic concepts and methodologies of a new general rock-bit interaction model useful in predicting and controlling drilling trajectories in directional (and deep vertical) wells.  It accounts for the anisotropic drilling characteristics of both the formation and the bit.  The model is developed in a 3-D geometry.  Therefore, it is capable of predicting the walk tendency and the build/drop tendency of a given BHA (bottomhole assembly) under any drilling condition.  The model can be used in the forward mode to predict the drilling direction; in the inverse mode to generate the rock and bit anisotropy indices; and in the log-generation mode to generate drilling logs, such as a drilling dip log.

Title: Method and apparatus for solid waste disposal
Inventor: WOJCIECHOWSKI CHRISTOPHER R
IPC: B02C18/08
Filed: 1989-05-29
Granted: 1991-05-14
Abstract: ABSTRACT OF THE PRESENT INVENTION   The present invention contemplates a multi-level collection area of solid waste products. On a top level of the collection site, ramp ways for trucks are provided so that the trucks may dump solid waste into a central collection opening. Gravity feeds the solid waste into a centrifugal spinner. The spinner includes radial agitator blades. The solid waste is spun and agitated on the spinner and centrifugal force tends to push the solid waste to the outer edge of the spinner. The spinner angles upward from the center to an outlet slot of uniform size disposed about the circumference of the spinner. A cover is disposed over the spinner having a plurality of fixed teeth disposed thereon. The combination of the cover and spinner is such that as larger pieces of solid waste are propelled towards the outlet slots, they are acted on both by the spinner and the blades of the cover, reducing them to a size small enough to fit through the outlet opening. The continuous rotating action also aids in preventing the clogging of the outlet opening. The centrifugal force of the spinner pushes the articles through the outlet slots and into a series of collection bins. The collection bins may include screens or filters for further controlling the size of the solid waste particles. Runways are provided beneath the bins for access by trucks. An opening in the bottom of the bin is used to release the uniform size solid waste particles into the truck for transportation to a land fill site. The uniform and small size of the solid waste particles results in improved mixing characteristics with earth, thus a uniform compaction with a minimum of settlement in the land fill, increasing the likelihood that the land fill will be suitable for uses requiring load support capabilities. Moisture is removed from the processed solid waste by a combination of grinding and centrifugal force. The bottom of the storage bins ispitched and includes as sieve so that any liquid exiting the outlet slot will flow through the sieve and be transported away from solid waste. By substantially reducing the liquid content of the solid waste, the land fill volume will have fewer organic fluids and liquids, reducing the amount of leachaids and the formation of methane gas.

Abstract: Abstract of the Invention In a rotary drill having a driven rotary table with an axially directed passage through its center of rotation defined by a hollow spindle, a kelly bar extending through the passage, and a chuck mounted on the spindle, plungers are mounted in cylinders in the chuck for radial movement into and out of engagement with shoulders on the kelly bar.  A housing surrounds a portion of the chuck.  The housing is held against rotation and has a fluid passage through it communicating with an annular manifold channel.  Fluid passages in the chuck, associated with each cylinder, communicate at one end with the manifold channel and at another end with the cylinder radially inboard of a piston part of the plunger.  Oil under pressure to move the plungers out is caused to leak into bearings positioned axially above and below the manifold, to lubricate, flush and cool them.  The plunger has a nose with a depending lip that engages an upper or lower shoulder of the kelly bar when the chuck is forced up or down to drive the kelly bar upwardly or downwardly.

Title: Thrombus-targeted complexes of plasminogen activator and fibrin fragments
Inventor: BUDZYNSKI ANDREI Z
IPC: C07K19/00
Filed: 1989-09-29
Granted: 1995-04-25
Abstract: Thrombolytic hybrids are formed as covalent or non-covalent  complexes  of  fibrin  fragments  and  plasminogen activator molecules.  Native plasmin degradation fragments of fibrin or non-native fibrin fragments are covalently or non-covalently linked to plasminogen activators such as t-PA, scu-PA, urokinase, streptokinase, and the like.  Useful native  fibrin  fragments which may be  utilized  to  form complexes with plasminogen activators include fragments E1, E2, E3, D and DD, and (DD)E complex.  The fibrin fragment component targets the hybrid to vascular thrombi, immobi-lizing the plasminogen activator molecule onto the fibrin surface of the thrombus.   Once localized on a thrombus surface, the plasminogen activator component of the hybrid activates only the clot-surface bound plasminogen trans-ported by the fibrin fragment vehicle, without significant systemic activation of plasminogen.  The hybrids are strong potentiators of plasminogen activator activity, generating more plasmin from fibrin-surface bound plasminogen than the plasminogen activator molecule alone.   The hybrids have a longer  half-life  in  circulation  than  the  corresponding unprotected plasminogen activator molecules.
