Abstract:
The disclosure teaches a polyurea coated water storage floatation cover comprising a layer of buoyant closed cell foam coated with polyurea, a upper layer of polyurea coated textile attached to the buoyant closed cell foam coated with polyurea, and attachment components affixed to the upper layer of the polyurea coated textile. The cover can be rolled up for storage and transportation. The cover can be reused. The cover can be made in sections that can be attached together to cover a large area of water surface such as in a retention pond or open top tank.
Abstract:
A secondary containment system for an above-ground petroleum storage tank includes a berm rising above the ground surrounding the tank and spaced apart from the tank for defining a petroleum retention basin about the tank. An impermeable liner covers the ground between the tank and the berm. At least one drain is formed through the liner and into the underlying ground. A hydrocarbon sensor monitors the presence of petroleum in the drain. A control device responds to the presence of petroleum in the drain by closing a containment valve to prevent discharge of petroleum from the basin. An indicator device provides at least one of an audible and visible signal indicating that petroleum is sensed in the drain.
Abstract:
A coupler assembly has first and second conductors with first and second dielectric supports extending along a coupling section and supporting the first and second conductors at a support section.
Abstract:
A method of manufacturing a plurality of secondary containment panels and assembling and installing the panels in a secondary containment system of an above-ground liquid storage tank or other retention facility includes forming a plurality of flexible substrate pieces. A liquid impermeable coating is applied to the upper surface of each piece such that an edge segment of the piece remains uncoated. The coating is applied to the substrate piece in an indoor enclosure using a computer controlled robotic sprayer that applies a uniform coating. A system for coating secondary containment panels. An apparatus for spraying a coating on secondary containment panels. The apparatus may be computer controlled and operate automatically to coat the surface of the panel.
Abstract:
A method of manufacturing a plurality of secondary containment panels and assembling and installing the panels in a secondary containment system of an above-ground liquid storage tank or other retention facility includes forming at least one flexible substrate. A liquid impermeable coating is applied by a robotic applicator to the upper surface of the substrate such that an edge segment of the substrate remains uncoated. The coating is applied to the substrate in an indoor enclosure having a flat surface. The coated substrate is delivered to the site of the tank and extended across the ground adjacent to the tank. At least a pair of the substrates are juxtaposed relative to one another such that a first one of the substrate overlaps the uncoated segment of the second substrate to form a seam. An adhesive substance is then applied to the seam to fasten the first and second substrate together.
Abstract:
A wafer support assembly has a first wafer support plate having a first grid pattern allowing first probe access through the first grid pattern to a first side of a wafer in the wafer support assembly and a second wafer support plate having a second grid pattern allowing second probe access through the second grid pattern to a second side of the wafer in the wafer support assembly.
Abstract:
An interconnection includes a microcircuit package having a slot, and a receiving feature. A bead ring is fitted into the receiving feature. A center conductor extends through a dielectric support disposed in the bead ring and through the slot. The center conductor forms a coaxial transmission structure in cooperation with the bead ring and the dielectric support, and forms a slab line transmission structure in cooperation with the slot.

A liquid impermeable coating is applied to the upper surface of each piece such that an edge segment of the piece remains uncoated. The coating is applied to the substrate piece in an indoor enclosure using a computer controlled robotic sprayer that applies a uniform coating. Metal plates are embedded in the floor used for quality control testing of the coating thickness using magnetic gauges. At least a pair of the pieces are juxtaposed relative to one another such that a first one of the pieces overlaps the uncoated segment of the second piece to form a seam.
