Abstract: An automated bulk tank pressure exhaust valve automatically exhaust air pressure from a bulk tank of a bulk tank trailer in response to a sensor operatively communicating with the exhaust valve sensing an absence of air pressure or air flow in a tank pipe communicating with the bulk tank. The sensor is also operatively communicated with in alarm that is activated in response to the sensor sensing air pressure or air flow in the tank pipe or a truck coupled to the bulk tank trailer.

Abstract: A dust filtering and collection system for filtering dust and other debris particles from an incoming dust laden air stream, such air stream generally being used for conveying granular material into or from a bulk tank trailer, a railroad car, or other conveying vehicle, the filtering system designed to be functioned by vacuum air pressure, operatively generated by a blower, to draw in the soiled air into the filter system, to cleanse such air for further use in the conveying of the granular material. The air flow may be reversed, to provide for a dislodging of any dust particles from the filtering system, and to cleanse the filter for further efficient usage of the system in conveying granular material into or out of the tank trailer, or other vehicle during usage. The filter system includes a pod of filter tubes encapsulated by a polymer header that mounts to a transverse plate that secures to the approximate upper end of the filter canister of the filtration system.

Abstract: A cam assembly of a cam and a cam post replace each threaded fastener used in attaching a tube plate to a support ring of a bulk tank filter canister. A plurality of cam assemblies replace the threaded fasteners of the filter canister and enable the tube plate to be easily and quickly separated from the support ring when servicing the filter tubes suspended by the tube plate in the filter canister.

Abstract: A filtration system for a dry bulk tank trailer includes a filter canister containing a filter media in the interior volume of the filter canister. The filter media divides the interior volume of the filter canister into a dusty air side and a clean air side of the interior volume on opposite sides of the filter media. A dusty air line operatively communicates the dusty air side of the interior volume with the dry bulk tank. A fitting operatively communicates with the clean air side of the interior volume. The fitting is operable to selectively communicate a vacuum pressure and a positive pressure to the clean air side of the interior volume.

Abstract: A pressure and heat molded polymer tube, formed of miniscule polyethylene beads, each in the vicinity of 115 um powder in diameter, which when compression molded forms pores that are of uniform diameter throughout their length within the range of 5 um-10 um, the tube having an upper flange, that mates within a correspondently shaped grommet, which when applied to the transverse plate of an air filtration housing, functions to cleanse highly efficiently the dust particles and debris from the air being filtered, when passing through the filtration system, so that such purified air can be discharged safely.

Abstract: A sealed manhole clamp securing a manhole cover to a weld ring, including a lever assembly, the lever assembly having a lever arm and a cam, a pivot bolt, the pivot bolt having a cylindrical upper portion, and a lower portion, the lower bolt portion threadedly engages upwardly within the cylindrical upper portion of the pivot bolt, the cylindrical upper portion being pivotally pinned to the lever arm, the lower bolt portion being pivotally mounted to a seal ring, wherein since the lower bolt portion threadedly engages within the cylindrical upper portion, the entrance of any debris, dust, or moisture is prevented from entering the region of this threaded engagement of the pivot bolt components.

Abstract: A dust filtering and collection system for filtering dust and other particles from an air stream generally being used for conveying granular material into or from a bulk tank, with the filtering system designed to incorporate structure, such as a specially designed grommet, for holding a porous filter tube for filtering out such dust particles, with a grommet having structure to provide for its interlocking and engagement with and through an aperture in a transverse plate within the system. The grommet has an upper flange, that engages the upper surface of the transverse plate, and has an inner flange for engagement with the upper edge of the filter tube, while the bottom of the grommet has resilient fingers and associated detents for engaging the bottom of the transverse plate, to furnish an interlocking of the grommet, with its supported filter tube, onto and through the transverse plate.

Abstract: A dust filtering and collection system for filtering dust and other particles from an incoming air stream generally used for conveying granular material, the filtering system receives the air from within the tank trailer, pre-separates the heavy dust particles and other debris at the bottom of a filter housing, without its impingement upon the filter tube(s) contained upwardly therein, and then passes the partially filtered air upwardly through filter tube(s) for purifying the air before discharge to atmosphere. The filter housing for the system includes a cylindrical housing upwardly, an integral cone shaped housing at its bottom, into which the dust particles settle, it has a transverse plate at its upper segment, which supports the filter tube(s), an air inlet being centrifugally and integrally formed at the bottom of the cylindrical member of the filtration system.

Abstract: The present invention discloses a method, in a network, of synchronizing a plurality of software development teams, with each team working on an assigned subset of a code development project. A repository comprising all code base of the code development project is provided and each team's assigned subset is correlated with every other team's assigned subset within the code development project. The repository automatically merges all team member inputs so that each subset is linked in a visual representation of each team's assigned subset to stories within connected subsets so that the real-time status of a connected subset may be graphically displayed. A real-time status of each assigned subset, including all correlations between each subset in the project can be determined and any team member, upon demand, can activate and display the visual representation of the real-time status of each subset, the relations between subsets, and the real-time status of the whole development project.
