Abstract: Metallic tube, pipe and conduit are made in a continuous process that includes a zinc galvanization stage, a first passivation stage, a second passivation stage and a third passivation stage. A colorant is added to the tube, pipe or conduit during the continuous manufacturing process, and the colorant imparts the appearance of a color, such as red. The continuous movement of the tube, pipe or conduit is not halted during normal operation of the tube, pipe or conduit manufacturing and coloring process.

Abstract: Perlite, particularly, perlite in powdered form, is employed to adsorb metals and metal compounds from fluids, in particular gases at elevated temperature. Treatment of perlite by boiling with sulfuric acid or suspending in a suspension of sulfur in carbon disulfide has been shown to significantly expand the surface area of perlite, thus increasing the efficiency of the process. In select embodiments, powdered perlite is treated to expand its surface area and injected into a fluid stream, such as flue gas, held for a specific retention period, and removed for subsequent disposal. In other embodiments powdered perlite is provided in an adsorption bed. Fluids containing metals or metal compounds in vapor form are permitted to pass through the adsorption bed until the expanded perlite powder is saturated (exhausted) with the metal and metal compounds adsorbed thereon. The perlite is then replaced, disposing of the exhausted perlite.

Abstract: The invention provides gas purification methods and systems for the recovery and liquefaction of low boiling point organic and inorganic gases, such as methane, propane, CO2, NH3, and chlorofluorocarbons. Many such gases are in the effluent gas of industrial processes and the invention can increase the sustainability and economics of such industrial processes. In a preferred method of the invention, low boiling point gases are adsorbed with a heated activated carbon fiber material maintained at an adsorption temperature during an adsorption cycle. During a low boiling point desorption cycle the activated carbon fiber is heated to a desorption temperature to create a desorption gas stream with concentrated low boiling point gases. The desorption gas stream is actively compressed and/or cooled to condense and liquefy the low boiling point gases, which can then be collected, stored, re-used, sold, etc.

Abstract: The present invention relates to a roller for slidably mounting a panel such as a shower door to a rail or to a similar structure. The roller comprises a first cylindrical portion including a rolling surface for engaging the rail and a second cylindrical portion fixedly securable to the shower door panel. The second portion is concentrically mounted to the first portion and is rotatable relative thereto. A resilient member such as a tension spring connects the first portion to the second portion and stores a potential energy when a user moves the shower door in one direction and automatically urges the shower door to move in the opposite direction when released by the user. The invention also relates to a roller assembly comprising a roller and a rail.

Abstract: A system and associated method for removing metal, including metal in vapor form, from high temperature fluid emissions such as may occur at the exhaust of furnaces or thermal treatment equipment. One embodiment is the Integrated Metal Emissions Control System (IMECS™) incorporating both a Steel Screen Particulate (SSP) Filter System and a Perlite Based Sorbent (PBS) System. IMECS™ uses the SSP Filter System, with pore sizes down to one micron, to capture toxic metal particulate materials and the PBS System to capture vapor phase metals using surface-modified perlite. Using the IMECS™, EPA-listed heavy metals have been removed from representative high-temperature emissions in field tests to easily meet the NESHAP standards.

Abstract: A preferred embodiment steady state tracking desorption system achieves steady tracking of either a fixed sorbate output set point, or a set point that changes over time. The system includes an electrically heated thermal adsorption/desorption device. A temperature sensor senses the temperature of an adsorbent material within the adsorption/desorption device. A sorbate sensor senses a sorbate level from an outlet of the adsorption/desorption device. A power sensor senses the power supplied by the desorption device. A controller interprets levels sensed by the temperature sensor, the sorbate sensor and the power sensor and provides a signal to achieve steady set point tracking of a sorbate level from the outlet of the adsorption/desorption device.

Abstract: Perlite, particularly, perlite in powdered form, is employed to adsorb metals and metal compounds from fluids, in particular gases at elevated temperature. In select embodiments, powdered perlite is treated to expand its surface area and injected into a fluid stream, such as flue gas, held for a specific retention period, and removed for subsequent disposal. In other embodiments powdered perlite is provided in an adsorption bed.

The perlite is then replaced, disposing of the exhausted perlite. Treatment of perlite by boiling with sulfuric acid or suspending in a suspension of sulfur in carbon disulfide has been shown to significantly expand the surface area of perlite, thus increasing the efficiency of the process.

Abstract: Perlite, particularly, perlite in powdered form, is employed to adsorb metals and metal compounds from a fluid flow. In select embodiments, the perlite is treated to expand its surface area and injected into a fluid stream, such as flue gas, held for a specific retention period, and removed for subsequent disposal. In other embodiments the perlite is provided in a fixed adsorption bed and the fluid flow permitted to pass through the bed until the perlite surface is exhausted. The perlite in the fixed bed is then replaced, with the exhausted perlite disposed of as appropriate. Treatment of perlite by boiling with sulfuric acid or suspending in a suspension of sulfur in carbon disulfide has been shown to significantly expand the surface area of perlite.

Abstract: A network-based system that provides functionality for controlling the content of printed menus includes an electronic data repository and a web-based application program. The electronic data repository contains descriptions of content items that may be selected to include within printed items. The electronic data repository also contains a set of rules that specify, at least, specific content items that are required. The web-based application program allows a user to interactively create a printed item that includes selected content item descriptions from the data repository, and to place an order for printed copies of a created printed item. The web-based application inhibits the creation of printed items that do not comply with the set of rules.

Abstract: As humans age, there is a general loss of accommodation, termed presbyopia, which eventually leaves the eye unable to focus on near objects. This loss in ability to focus on near objects is a consequence of continued growth of the lens and crowding of the lens, zonules and ciliary body within the posterior chamber. Expansion of the posterior chamber is achieved by placing radial incisions in the sclera over the ciliary body. The method of correcting presbyopia according to the present invention is by making permanent the expansion of the sclera produced by incisions made in the sclera over the ciliary muscle by means of tissue barriers placed in the incisions, preventing contraction of the incision, and acting as a retainer of the increased circumference. With expansion of the posterior chamber, the effective working distance between the lens and ciliary muscle is restored and presbyopia reversed. The tissue barriers of the present invention are solid bars containing pre-placed integral sutures for fixation.
