Abstract: A contaminant adsorption is provided that includes a self-assembled monolayers on mesoporous supports (SAMMS) on a lattice support structure such as sintered metal wire mesh. Individual wire fibers of the sintered wire mesh may have a film coating of mesoporous material that is functionalized for a target metal.

Various improvements are disclosed including a new mechanism for positioning wedge shaped arcuate segments between the door and the sub body, a retainer mechanism for guiding movement of cross bars, a split hinge adjustment mechanism for adjusting planarity and concentricity between the closure door and the sub body, an increased annular wall body thickness region surrounding the sealing surface for reducing warpage during welding, a pressure lock rod member which also engages a combination of cross bars and a crank for driving the cross bars, and a pry bar that can facilitate better manually operated leveraging of the closure door.

Abstract: An apparatus for use in the treatment of contaminated fluid is provided. The apparatus includes a body portion, made from a mixture of a waste adsorbent material and a binder material, for use in the removal of contaminants. The adsorbent material may be a nanosorbent material manufactured from self-assembled monolayers on mesoporous supports (SAMMS). The binder material, on the other hand, may include any thermoplastic material capable of binding the adsorbent material together to subsequently provide a composite material that can be shaped into a block. A method for treatment of contaminated fluid is also provided.

Abstract: A filtration vessel is shown for use with a rotary screw compressor which receives a compressed liquid/gas mixture from the compressor. The vessel utilizes a first stage vortex knockout region to remove bulk liquids through a circular motion which imposes centrifugal forces on the gas and liquid mixture. A coalescer region located above the vortex knockout region receives the relatively lighter fluids and separates any remaining entrained liquids from the fluids. The discharge from the filtration unit is an essentially liquid free compressed gas. The liquid discharge, in the case of lube oil can be recirculated to the compressor for another cycle.

Abstract: A closure is shown for an equipment sub having a generally cylindrical aperture leading to a bore and a bore stop. The closure is a circular body having a O-ring seal on a peripheral flange. A common actuating means moves spaced arcuate segments located on the circular body outwardly into contact with the bore stop provided in the bore of the equipment sub.

Abstract: A pilot-operated, pressure-loaded, movable diaphragm-type gas-flow regulator valve is shown which is used in flow control applications. A regulator body internal port arrangement interconnects two independent throttling mechanisms in series. Two throttle plates are located within the regulator valve body relative to an inlet chamber and an outlet chamber. A movable diaphragm is positioned relative to a throttle plate by a separate pilot control system to vary the area of throttle plate exposed to flow, and thus, the flow rate of the regulator valve. The throttle plates each have drilled flow apertures which control flow through the valve. Smaller flow apertures are opened before larger flow apertures as the valve diaphragm lifts, thereby ensuring stability at low-flow conditions, while providing high capacity at maximum diaphragm lift.

Abstract: The present invention relates to an apparatus for separating liquids and solids from a gas stream and simultaneously coalescing liquids from the gas stream. The apparatus includes a closed vessel having a longitudinally extending length, an initially open interior, an input port at an extent and an output port at an opposite extent thereof. There is a partition located within the vessel interior that divides the vessel interior into a first stage and a second stage. There is at least one opening in the partition. A separator/coalescer filter element is disposed within the vessel to sealingly extend from within the first stage through the opening into the second stage. There is a chevron-type seal or an O-ring seal between the filter element and the opening.

Abstract: A homogeneous mixture of a base and a binder material or fiber that is compressed to form a mat or sheet of selected porosity. The binder material has at least a surface with a melting temperature lower than that of the base fiber. The sheet is formed into a selected geometric shape and thermally fused to bind the base fiber into a porous filter element. The preferred shape is a helically wound tube of plural sheets, each sheet being self-overlapped and compressed to overlap another sheet. Each sheet preferably heated and compressed individually and the sheets may be selected to have different porosities and densities. The binder fiber is selected from the group consisting of thermoplastic and resin, and the base fiber is selected from the group consisting of thermoplastic and natural.

Abstract: This invention relates to devices for removing covers for utility installations, such as water meter shut-offs, that are located under streets, sidewalks, and the like. Such covers provide accessible protection for the utility devices that they cover. Embodiments of this invention include a tubular shaft, and a hammer rod which is slidably insertable within the shaft and has a combination chisel point - claw hook at its the lower end for penetrating through pavement material, dirt and the like that may have become deposited in the aperture of the cover, to enable the claw hook to latch beneath the cover and pull on one side of the cover to lift it upward. Through impact on the top of the shaft by the hammer arm via corresponding impact surface, the chisel point on the shaft may be hammered downward to cause it to penetrate into the aperture.

Abstract: A vortical-type separator for removing from the gas stream suspended particulates present in the gas stream has an internally generated scavenging gas flow and a pulse jet system for cleaning scavenging gas filter elements. The separator has two or more conduits that are coaxially positioned with an annular clearance at their ends. A gas swirl device creates a swirling motion, causing heavier particulates to be discharged out the annular clearance or ejection port into a scavenging gas plenum. A flow path is created between the scavenging gas plenum and the outlet of the separator, with the pressure differential between the outlet and the ejection port causing scavenging gas to flow to the outlet. A frame is mounted in the flow path over which a bag filter is secured. The dust-laden scavenging gas flows through the bag filter and out the outlet. A nozzle is positioned at the mouth of the bag filter for periodically discharging a pulse of clean gas into the bag filter reverse to the flow of the scavenging gas.
