A grease trap or solids collector for separating waste from waste water has a tank having a multilayer outer wall made of an outer layer of un-foamed plastic, an intermediate layer of foamed plastic, and an inner layer of unfoamed plastic; an inlet invert in the tank for receiving incoming waste water; and an outlet invert for removing water from the tank. An extension collar made up of segments can be included.

A tank (e.g., an underground storage tank), and manufacturing methods therefore, may include a tank body having an exterior surface. A component is mounted on at least a non-planar portion of the exterior surface of the tank body using an adhesive (e.g., an MMA adhesive). For example, the component may be positioned on the non-planar portion of the exterior surface of the tank body after application of adhesive and pressure may be applied to maintain the position of the component on the non-planar portion of the exterior surface of the tank body as the adhesive is cured. The pressure may be removed upon curing of the adhesive and formation of a structural bond may occur at the adhesive interface between the mounting surface of the component and the non-planar portion of the exterior surface of the tank body.

A lower cost, light weight, hermetic system and method for storage of dry commodities outdoors for up to 1000 tonnes of commodity includes a multilayer joined material with a thickness of 0.2-0.3 mm, a weight of approximately 200 g/m.sup.2, a permeability to oxygen of less than 3 cc/m.sup.2/day and a permeability to water of less than 4 g/m.sup.2/day, a tensile strength of approximately 38 MPa, and insect penetration-resistance of approximately 1200 g/m.sup.2 (Dart test value).

The invention relates to a thermally insulated transport container with a housing for forming a space for goods, with walls and a thermal insulation abutting the walls as well as a wall structure of such a container. In particular, the invention relates to such a container as an air cargo container. According to the invention, sandwich plastic plates are provided as walls, with a honeycomb core welded on both sides to one covering ply, respectively, the honeycomb core and the covering plies consisting of a thermoplastic material, preferably PP. In this case, the walls are, in particular, a thermoplastic sandwich panel, consisting substantially of a PP (polypropylene) honeycomb core and PP covering layers, in particular glass-fiber reinforced, which are, with regard to the materials, homogenously connected to each other by thermally fused connection. Such plates are offered, for example, by Wihag Composites GmbH & Co. KG under the trademark MonoPan, which are preferred in this case. The use of thermoplastic material makes it possible for adjacent sandwich plastic plates to be attached to each other by welding, particularly in the region of the edges. In particular, it is thus possible to produce largely frameless and thus lighter transport containers.

A method for forming a structural wall section by sandwiching a corrugated metal panel between correspondingly corrugated EPS inner and outer panels. Also disclosed is a structural wall formed from a corrugated metal wall sandwiched between inner and outer EPS panels with a corrugated side on each of the EPS panels engaged with the corrugated metal panel.

A thermal barrier panel, the panel having a top face overlying a monolithic core, the core comprising a mixture of expanded glass granules, ceramic microspheres and a calcium aluminate cement binder, the expanded glass granules are selected from the group consisting of small granules having a size of about 0.5 mm to 1.0 mm, intermediate granules having a size of about 1.10 mm to 2.00 mm, and large granules having a size of about 2.10 mm to 4.00 mm wherein the volume of intermediate size granules comprises more than 50% of the mixture of expanded glass granules and the balance comprises small and large granules in a ratio of 1:2. The invention is also directed to a shipping container fitted with the fire containment panels of the present invention.

A calcium aluminate cement protective coating is resistant to sulfuric acid and can be used as a lining to protect surfaces in sulfur storage vessels and sulfuric acid storage vessels. The protective coating can include calcium aluminate cement, calcium aluminate based synthetic aggregates, and water. The protective coating is resistant to sulfur and sulfuric acid attack, and thus can be used to protect surfaces inside sulfur storage pits, sulfur storage tanks, and sulfuric acid storage containers.

A composite molded cargo body panel including a core, an interior skin secured to a first side of the core having a thickness, and exterior skin secured to a second side of the core, and a plurality of recesses. The plurality of recesses are dispersed along a first direction at intervals in the interior skin, with the core thickness at each of the plurality of recesses being reduced compared to a maximum core thickness, and each of the plurality of recesses defines a support surface. A pocket is formed in each of the plurality of recesses, with the core thickness at the pocket being less than the core thickness at each of the plurality of recesses. A plurality of logistics inserts are attached to the respective support surfaces of the plurality of recesses so that, at each of the plurality of recesses, the logistics insert extends across the pocket.

The present invention is directed to an air cargo container formed from a plurality of fiber-reinforced (e.g., carbon fiber) composite panels. The use of fiber reinforcement provides for an increased strength-to-weight ratio as compared to existing air cargo containers. Furthermore, the present invention also includes air cargo containers having convex side panels, which decreases the chance of damage to the container or to its contents in the event of an impact. The air cargo container is collapsible, with panels able to be stacked for more efficient storage.

A sectional panel tank comprises one or more side wads that are joined together in forming the sectional panel tank. One of the side wall comprises a first unit panel having a first extension at a first edge of the first unit panel and a second unit panel having a second extension at a second edge of the second unit panel. By combing the second extension to the second extension, the second unit panel is joined to the first unit panel for providing a continuous surface of the side wall. No gasket is needed between the first extension and the second extension. A method of making the sectional panel tank is also disclosed. A method of making prefabricated unit panels with lining sheets is further disclosed for the sectional panel tank.
