Abstract: A system is mounted onto a forklift truck for covering and/or uncovering a cargo with a tarpaulin. The system comprises a tube frame assembly having a telescoping frame slidably attached to it. The telescoping frame is configured to be capable of being extendable and/or retractable within the tube frame assembly. The telescoping frame comprises a plurality of rollers configured to be capable of rotating when engaged with the plurality of flexible members and the flexible cover. A powertrain device is installed onto the tube frame assembly for causing to retract and/or to extend the telescoping frame within the tube frame assembly. A winch assembly is configured to be coupled to the tube frame assembly and having a plurality of straps engaged with the tarpaulin to cover and/or uncover the cargo.

Abstract: Apparatus for mixing aqueous foam with a slurry of gypsum and water. A cylindrical housing includes, in its upper end, an inlet for a slurry and a helical diverter for directing the slurry in a downward spiral flow path. An inlet for aqueous foam in located in said diverted and directs the foam into the incoming slurry. An annular flow restrictor is located in the lower end of the housing. Turbulence resulting from diversion of the incoming slurry from linear flow to a downward spiral flow path and from changes in spin diameter and speed through the flow restrictor uniformly mix foam with the slurry.
