This invention provides a collapsible container for holding product therein during shipment and being returned for reuse that has a body including at least two collapsible side structures with support members attached thereto. Dunnage is suspended from the support members. The dunnage comprises a plurality of flexible members, at least some of the flexible members having stabilizers attached to the flexible member for stabilizing and protecting product being shipped. In one embodiment, tracks may be attached to opposite sides of the body, and support member assemblies extend between the tracks. Dunnage is suspended from the support member assemblies. Portions of the support member assemblies move in the tracks to move products suspended by the dunnage to a more ergonomically friendly position for loading or unloading.

In accordance with one aspect of the present invention, a portable exhaust fan for removing airborne materials from a localized area is disclosed. The portable exhaust fan comprises: a housing having an inlet opening and a discharge opening and configured so as to define an air passageway between said inlet and discharge openings; a blower unit mounted within said housing such that rotating blades of said blower unit are located within said air passageway to draw air into said inlet opening and to cause said drawn air to travel through said air passageway and to exit through said discharge opening; a flexible tube having a proximate end connected to said inlet opening of said exhaust fan and a distal end for placement in the localized area such that air drawn into said inlet opening is air located primarily in the localized area and travels through said flexible tube; and an inlet filter removably attached over said inlet opening of said tube such that air drawn into said inlet opening travels through said inlet filter, wherein said inlet filter is constructed and arranged to remove airborne materials that can accumulate in said tube or said housing unit.

A container for holding product therein during shipment and being returned for reuse has a metal frame, tracks having horizontal and vertical portions attached to opposite sides of the frame, and a plurality of support member assemblies extending between the tracks. Each support member assembly comprises end members located at the ends of a tubular support, the end members being movable in the tracks. The support member assemblies support dunnage for supporting products for storage or shipment.

A container for holding product therein during shipment and being returned for reuse has a movable door assembly, front frame, tracks supported by opposite sides of the container, and a plurality of dunnage supports extending between the tracks. The dunnage supports may comprise multiple pieces including end members and a tubular support, the end members being movable in the tracks. The dunnage supports support dunnage, such as pouches, for supporting products during storage or shipment.

Each support member assembly comprises sliders or end members located at the ends of tubular supports and being movable in the tracks. The support member assemblies support dunnage for supporting products for storage or shipment.

The invention relates to a shoal sea area rescue operational ship with a pile driving and pulling device. A through hole allowing driving and pulling of a pile is arranged on a deck of an operational ship body, a hollow hoisting truss is fixedly connected on the ship body deck at the upper edge of the through hole, the vertical pile is suspended in the hoisting truss, racks are symmetrically and longitudinally arranged on the lateral side of the outer surface of the pile, and a lifting mechanism which drives the pile to reciprocate longitudinally and enable the pile to be driven in or pulled out of the seabed is meshed with the racks. By means of driving of the pile by the pile driving and pulling device arranged on the ship body, the ship body can be stably fixed to a shoal sea area to set rescue equipment, personnel and corresponding goods and materials down, and after rescue is finished, the ship body can be unfixed to sail freely by means of pulling of the pile by the pile driving and pulling device. The deck of the fixed rescue ship body can serve as a reliable operating platform.

The invention discloses a copper-modified nitrogen-doped titanium dioxide material, and a preparation method and application thereof. The preparation method includes mixing dimethylformamide with anhydrous ethanol while stirring to obtain a clear mixed solution; adding tetrabutyl titanate into the mixed solution obtained in the previous step, and performing uniform stirring to obtain sol; dropwiseadding an anhydrous ethanol solution of copper chloride and a citric acid solution into the obtained sol, and dropwise adding acetic acid after uniform stirring; subjecting the obtained sol to ultrasonic treatment to obtain uniform wet gel; washing the wet gel obtained in the previous step with absolute ethanol prior to drying to obtain copper-modified nitrogen-doped xerogel, and grinding the xerogel into powder; calcinating the obtained powder, and grinding the powder again to obtain the copper-modified nitrogen-doped titanium dioxide material. The copper-modified nitrogen-doped titanium dioxide material prepared by the preparation method has strong photocatalytic reduction performance under visible light.

A container for holding product therein during shipment and being returned for reuse has a base and opposed sides, L-shaped tracks, and a plurality of padded dunnage supports extending between the tracks. One type of padded dunnage support comprises end members and a tubular middle member, the end members being movable along the tracks. The padded dunnage supports support dunnage, such as pouches.

A container for holding product therein during shipment and being returned for reuse has a frame, tracks supported by opposite sides of the frame, and a plurality of dunnage supports extending between the tracks. At least one of the tracks on each side is generally U-shaped and at least one is linear. Each dunnage support may comprise end members and a middle member, the end members being movable along the tracks. The dunnage supports support dunnage for supporting products for storage or shipment.

This exhaust gas scrubber for an epitaxial wafer manufacturing device includes: a scrubber inlet tube for introducing an exhaust gas discharged from an epitaxial wafer manufacturing device; and a wash tube unit formed inside the scrubber inlet tube for spraying wash water toward an interior of the scrubber inlet tube from one end thereof so as to wash adhesions inside the scrubber inlet tube, wherein the wash tube unit includes an outer tube through which inert gas constantly flows, a middle tube which is formed inside the outer tube and through which inert gas intermittently flows, and an inner tube which is formed inside the middle tube and through which the wash water and inert gas alternately flow.

The main object of the current invention is to provide an apparatus, that can be installed on a flat bed truck, pre-market or post-market, which allows barrels, to efficiently and safely, placed or removed from a road or other work site.
