Abstract: A system for separating bitumen from shingle powder includes: a blender; a solvent tank in fluid communication with the blender; a water tank in fluid communication with the blender; a decanting tank in fluid communication with the blender; a distillation tank in fluid communication with the decanting tank; and a plurality of pumps for pumping fluids between various components of the system or out of the system. When the system is in use, the blender receives and mixes solvent from the solvent tank with shingle powder containing bitumen to produce a bitumen-infused solvent. Water is supplied to the blender from the water tank to wash an interior of the blender. Bitumen-infused solvent received in the decanting tank from the blender is separated from excess water. Bitumen within the bitumen-infused solvent is isolated within the distillation tank.

Abstract: In combination with a truck bed a low profile storage box. A storage box having an improved security system which engages the interior exposed side of said truck bed.

Abstract: Medical devices for removing gasses, such as gas bubbles and/or dissolved gasses, from a liquid to be delivered to a patient, and methods of use and making of such devices. In at least some embodiments, a gas permeable membrane material is used in the construction of the gas removal devices. In some embodiments, layers of gas permeable membrane material are used to construct a filter structure for removing gas from the liquid. In other embodiments, hollow tubes and/or fibers of the gas permeable membrane material are used to construct a filter structure for removing gas from the liquid. The gas removal devices may be used in any of a broad variety of liquid delivery systems and/or configurations.

Abstract: A self-powered, personally wearable air purifier includes a sequence of packed bed filter media packets having filter media therein of specifically targeted types that will absorb those ambient air pollutants that have been identified as being particularly dangerous to human health. A HEPA filter is included for the removal of particulate matter that will have adhered thereto many of such pollutants. Media types can be selected to meet different environmental circumstances, including normal highway or city center air, or terrorist attacks of chemical, biological or “dirty bomb” types as on a battlefield or similar environments. Shoulder straps and a chest strap are provided for wearing the apparatus on a user's back, or other means such as a shoulder pouch can also be employed. Emergency substitution of filter media using thermal insulation from the clothing of the user is available upon depletion of the normal media material.

Abstract: An apparatus accepts randomly arriving blocks of parallel digital data of varying bit lengths termed datum segments that may have been generated by stripping leading zeros from bytes of a fixed size, each having associated therewith a bit count code that expresses the bit length of each datum segment in the form nnnnndddd . . . , the “n” being the bits of the bit count code in such number as to encompass the memory capacity of a receiving device to which the datum segments are to be sent, and the “d” representing the actual datum segment bits. The apparatus concatenates the nnnnndddd . . . expressions to form a continuous bit sequence that is saved so that each nnnnndddd . . . expression is accessible thereafter through the computer address therefor, such use preferably being by a circuit of matching bit length, the format, however, allowing the original form of the data to be recovered if desired.

Abstract: Process and apparatus for treating an aqueous effluent with high concentrations of silver and ferric/ferrous complexes using multiple additions of one or more water-soluble sulfur containing polymer chelating agents, with optional additions of non-polymeric sulfur containing compounds. The presence of a high concentration of both dissolved silver and ferric/ferrous complexes prevents efficient silver removal by precipitation and the achievement of a very low residual silver concentration. By using multiple additions of the chelating agent(s), a higher degree of silver removal can be achieved than would be possible with the same amount of chelating agents added in a single stage. Effluent from photo finishing operations, particularly minilabs, can be effectively treated so that there is essentially no silver remaining in the treated effluent.

Abstract: A water ski handle including a frame member. The frame member has a back bar and a pair of side bars integral the back bar. One of the side bars extends from one end of the back bar, while another of the side bars extends from another end of the back bar. Each side bar has an inwardly curved portion near a distal end. A handle bar is positioned through the distal ends of the left and right side bars of the frame. Lastly, a rope connector is tied to the handle bar. The rope connector is capable of coupling with a water ski tow line. The rope connector, when coupled with the tow line, allows the skier to be pulled through the water when holding the handle bar coupled to the frame.
