  • Publication number: 20040208282
    Abstract: A portable apparatus for sanitizing and recovering mail and other materials is disclosed. The apparatus is employed after a known or suspected biological attack or contamination event, such as anthrax. Multiple X-ray sources penetrate mail and other materials, and destroy the biological agents. The apparatus is taken to the location of the biological problem, as opposed to shipping contaminated materials to a fixed facility for recovery. Many safety and practical advantages result from this approach to bio-terrorism or to biological contamination events. The design of this apparatus leads to a self-cleaning feature. Airflow control prevents escape of toxic biological materials into the environment.

  • Publication number: 20040179896
    Abstract: A concrete receptacle assembly includes a frame that supports a series of cells that are used to receive waste concrete and mold the waste concrete into synthetic riprap blocks. The cells are defined by a series of angled partitions that are mounted within the frame, with the angled partitions defining the shape of the synthetic riprap blocks produced. In operation, the waste concrete is distributed into the cells, where it is allowed to cure for a predetermined period of time. Once cured, the concrete receptacle assembly is upended such that the synthetic riprap blocks will be dislodged from the cell. Once the synthetic riprap blocks have been extracted, the concrete receptacle assembly is prepped for the next cycle of production.

  • Patent number: 6746849
    Abstract: Nucleoside diphosphates (NDPs) are detected or measured by following the dephosphorylation of the phosphoenzyme form of nucleoside diphosphate kinase (NDPK), and nucleoside triphosphates (NTPs) are detected or measured by following the phosphorylation of NDPK to its phosphoenzyme form. A typical process involves (a) causing NDP in sample to bind to NDPK phosphoenzyme, or causing NTP in sample to phosphorylate NDPK and (b) detecting a change in a characteristic of the enzyme which differs between its phosphorylated and unphosphorylated forms. This may be aided by labelling the enzyme. Quantitative data can be obtained. Both in vivo and in vitro measurements can be made.

  • Patent number: 5705056
    Abstract: A separator (10) for separating a heavier liquid from a lighter liquid is disclosed which is intended to operate between a fuel tank (12) and a fuel pump connected to the fuel outlet (24) of the separator (10). The separator includes a float (30) which is light enough to float on the heavier liquid and which is heavy enough to sink in the lighter liquid. The float controls opening and closing of a valve (44, 46) through which heavier liquid is disclosed from the separator. As heavier liquid accumulates, the float lifts to open the valve (44, 46). A plate (34) subjected to a force caused by fuel flowing into the separator through the inlet (16) prevents the float opening the valve whilst the separator is in sub-atmospheric pressure. The plate can be replaced by a diaphragm which is subject on one side to atmospheric pressure and on the other side to the pressure in the separator.

  • Patent number: 5693188
    Abstract: Apparatus for the thermal conversion of solids containing hydrocarbons. In one embodiment for solids which can be converted entirely to vapour, pieces of the solids are continually fed into a molten lead bath in an oxygen free atmosphere in an elongated conversion chamber. An auger partially immersed in the lead bath carries the floating pieces along in the molten lead bath until they are gradually converted to hydrocarbon vapour which rises upwardly to a condenser. In another embodiment for solids which can be converted to a vapour, particulate matter and residual solids, the lead bath extends further into a separation chamber with an inclined retaining skirt extending between the conversion chamber and the separation chamber, The auger forces the particulate matter and residual solids remaining after vaporization down under the inclined skirt, but the hydrocarbon vapour is prevented from escaping into the separation chamber.

  • Patent number: 4053012
    Abstract: An apparatus and method for gravity molding articles such as battery straps or the like in open or non-pressurized molds. The apparatus uses an upwardly inclined molding head including a molten metal reservoir and a nozzle discharge end positioned adjacent the mold for delivering molten metal into the mold. Delivery of molten metal can be from a molten lead vat through a siphon conduit and stop-cock valve at the mold head. At the end of each pour, upon closing of the stop-cock valve, a small amount of molten metal is withdrawn from the heated reservoir into a suction system to decrease the level of the reservoir slightly below the lower lip of the nozzle end and thereby prevent dripping from the nozzle end between pours. At the beginning of each pour, the molten metal is released from the suction system back into the reservoir for use in the pour.
