Apparatus in fluid communication with a water leg portion of a hydrocarbon-contaminated water, e.g., a water leg portion of a produced water stream or an offshore drilling or production platform sump tank for conveying water, separated from oil, into contact with non-woven fiber / particulate polymer coalescing media-containing canisters such that the hydrocarbon droplets and other organic material droplets commingled with the sump tank or produced water will be coalesced by passage through the coalescing media. The canisters preferably are provided in a plurality of stacks in each vessel. Solids that do not pass through the canisters are accumulated at the bottom of the vessel and easily drained through a drain port. The water and hydrocarbons will pass through the coalescing media within the canisters and will be separated easily from each vessel, e.g., by gravity separation, sot that the water can be conveyed back to the ocean water without contamination.

A one step entry pedicular preparation device works well with Minimal Invasive Spine Surgery (MISS) to facilitating such approach. A related intervertebral disc access system and pedicle screw compatible with the systems is also illustrated. The systems include a manipulator having a bar handle and main body with main barrel bore a pedicle dart having a proximal tip end and a second distal open end selectably attachable to the manipulator using a variety of interconnect configurations, both of which work in conjunction with a guide pin. The pedicle darts can be made of any material, disposable or re-usable and can be utilized for a variety of purposes, including bone structure formation for faster conventional pedicle screw insertion with precision and vertebra fixation.

A suture anchor is described which in one form may be easily fabricated from extruded material by angular cuts and bore holes which provide an offset pulling force to the suture. In an alternate and preferred embodiment the suture anchor is injection molded having an annular displaced corner and abutment wall which act to seat the suture anchor firmly within a bore hole. Novel application means are also disclosed which hold the suture anchor on a frangible shaft for insertion and upon completion of the insertion permit fracture of the frangible portion and removal of the instrument. In another form of the invention, the suture anchor comprises a substantially wedge-shaped body having a smaller distal end and a larger proximal end, means thereon for retaining a suture, and means thereon for releasable connection to an inserter shaft; a boundary surface and a plow surface of the body intersecting to form a biting edge at the proximal end of the body; and the boundary surface and an abutment surface of the body intersecting to form a cam surface at the proximal end of the body; and the biting edge being adapted to be in engagement with a first wall portion of a bore in a bone and the cam surface being adapted to be in engagement with a second wall portion of the bore opposed to the first wall portion; wherein tension on the inserter shaft is operable to move the cam portion along the bore second wall portion and rotate the body in the bore such that the biting edge bites into the bore first wall portion to lock the body in the bore.

A plasma display device that diversifies heat dissipating paths of integrated circuit modules in a circuit board assembly, thereby enhancing heat dissipation of the integrated circuit modules. The plasma display device includes a plasma display panel, a chassis base on which the plasma display panel is attached and supported, integrated circuit modules that are mounted on the circuit board assembly on an opposite side of the chassis base to the plasma display panel, and heat sinks, each being attached to one side of each of the integrated circuit modules to dissipate heat therefrom. The heat sink is formed such that one end thereof extends to come in contact with the chassis base.

A heat spreader including a plurality of carbonaceous particles present in an amount of at least about 50% by volume of the heat spreader. A non-carbonaceous infiltrant is also present in an amount of at least about 25% by volume of the heat spreader, the non-carbonaceous infiltrant including an element selected from the group consisting of Cu, Al and Ag. In another aspect, the carbonaceous particles may be sintered or fused directly to one another. The heat spreader can be incorporated into a cooling unit for transferring heat away from a heat source, which includes a heat sink with the heat spreader disposed in thermal communication with both the heat sink and the heat source.

A lacrosse stick includes a flared (e.g., forked) end and a flexible head frame adapted to receive a mesh thereon.

A land mine pressure fuse avoidance system has a base. A tread on the base contacts the ground around a land mine and independently distributes pressures around the ground. The tread has plural independent closed cell foam rubber elements. Each element is separated from adjacent elements for independently supporting only a portion of a load on the base, while other similarly independent elements support remaining portion of the load. The base is a cylindrical tire, a continuous track, a shoe sole attachment or a robotic foot, and the tread is conformed to and extends outward from the base. The independent elements of the tread are made of closed cell foam rubber formed as a tread on the base with notches between adjacent elements of the tread. Notches extend longitudinally along the tread, and notches extend across the tread, forming block shaped elements extending from the base. The notches extend into the tread for distances greater than heights above ground of clutter and of partially buried mines or fuses. In one form the tread has independent radially extending elements constructed of closed cell foam.

The invention relates to a dry powder pump comprising a bottle body, a cap, a piston and an elastic element, wherein an inner cavity of the bottle body is used for containing powder; the cap is connected to a mouth of the bottle body to form a piston cavity; the piston is driven to slide up and down by a head cap and then is limited and installed in the piston cavity to form an air compressing mechanism; and the elastic element makes the piston have a resetting trend. The dry powder pump is characterized in that a one-way valve is arranged in the mouth of the bottle body, an air inlet and the one-way valve is communicated with the piston cavity, and an air outlet of the one-way valve is communicated with the inner cavity of the bottle body; and the upper end of a hollow pipeline is communicated with a nozzle on the head cap, and the lower end of the hollow pipeline passes through the mouth of the bottle body to extend nearby the bottom of the bottle body and is directly or indirectly communicated with the inner cavity of the bottle body. The dry powder pump has the advantages of reasonable and practical structure, favorable sealing performance, convenient operation and use, light weight and convenient carrying and is easy to spray mixed powder and air.

A photomask blank has a resist film comprising (A) a base resin, (B) an acid generator, and (C) a basic compound. The resist film further comprises (D) a polymer comprising recurring units having a side chain having a fluorinated hydrocarbon group which contains a carbon atom to which a hydroxyl group is bonded and vicinal carbon atoms bonded thereto, the vicinal carbon atoms having in total at least two fluorine atoms bonded thereto. Addition of polymer (D) ensures uniform development throughout the resist film, enabling to form a resist pattern having high CD uniformity.

A bracelet-style watch having a case, a wristband formed integral with the case, and three separating element is disclosed. The separating elements, located on the case and wristband, form a space between the timepiece and the wrist. The space permits air to freely enter a substantial portion of an area between the timepiece and the wrist, thereby ventilating and reducing the quantity of perspiration that collects between the timepiece and the wrist.
