A system and process are provided for recovering and/or cleaning residual or waste petroleum products such as sludge accumulated within a storage tank or upon process equipment surfaces, or from inorganic materials such as sand or clay, and the like. The system and process include a negatively charged aqueous-based dispersion fluid, which is contacted with the petroleum product under controlled relatively high pressure and high shear conditions for fluidizing hydrocarbon molecules and for preventing such molecules from adherence to process equipment surfaces, or contaminants such as sand or clay. Additional mechanical separation as by subjecting the mixed petroleum product and dispersion fluid slurry to sonic vibration may also be employed. The thus-fluidized slurry of petroleum products, dispersion fluid, and inorganic materials can be separated by conventional techniques, as by settling and/or flotation, for further individual processing and/or re-use.

Structures based upon periodic cellular materials that provide a potential for defeating combinations of both air blast loading and ballistic attack either sequentially or simultaneously, or combination of both. The cellular structures may also be configured to meet the stiffness and strength support requirements of particular vehicle or other applications, systems or structures. The armor is therefore potentially able to support normal service loads and defeat blast and ballistic threats when necessary. The structure provides for using efficient load support capabilities of the material (without a high armor protection level) in low threat conditions, as well as the ability to modify the system to increase its level protection to a desired or required level. This would reduce the weight of the protection system in normal (low threat) conditions which reduces vehicle wear and tear, as well as cost savings in fabrication of applicable structures or systems.

A sealing device with film sealer for localized heating to bond film material as in one having a high temperature resistance (e.g., ceramic) substrate with a properly sized groove for receiving a heater element as in a flat faced wire band in a tight, flush to adjacent film presentation surface arrangement. A stacked ceramic plate set with a wire band received within a groove defined by a smaller height intermediate stack insert is a suitable substrate. The band is retained flush by a positioner fixer system that securely locks down one end for band tightening and the other end is provided at an access location of said housing body for clamping and tensioning the heater element into ready for use position within the groove. The edge sealer is suited for use as a product-in-bag sealing device (products such as air, foam, foodstuff, etc.) with the heater element placed in contact with film material to form a seal. A drag seal arrangement, where film layers are drawn past a fixed or adjustably mounted heater element to achieve bonding of one plastic film layer to another, is an example. The invention avoids repeated sealer replacement particularly when the film source (e.g., a film roll) has yet to run out.

A device for manipulating a tarpaulin so as to selectively cover and uncover a top aperture of a container. The top aperture defines an aperture peripheral edge, the aperture peripheral edge including two substantially opposed substantially longitudinal segments.

A method for applying a chromium containing coating to an underlying metal substrate where the metal substrate has an overlaying platinum-containing layer, as well as a corrosion resistant coated article thereof. A chromium-containing layer is deposited on the platinum-containing layer with an aluminide diffusion layer being deposited on the chromium-containing layer, the aluminide diffusion layer having an inner diffusion layer adjacent the chromium-containing layer and an outer additive layer adjacent to the inner diffusion layer. The chromium-containing layer is deposited by a deposition technique that permits chromium in the chromium-containing layer to more readily diffuse into a subsequently deposited aluminde diffusion coating layer. The chromium-containing and aluminide diffusion layers are then treated to cause chromium from the chromium-containing layer to diffuse into the outer additive layer in an amount of at least about 8%. The resulting coated article is resistant to corrosion.
