Abstract: A method for sealing a roof is disclosed herein. The roof is of the type comprising an inclined substrate and a first layer of shingles. The first layer of shingles has a first side and a second side wherein the first layer of shingles first side is attached to the substrate. The method comprises a first party selecting a second party to seal the roof. The first party provides a waterproof membrane having a first side and a second side to the second party. The second party positions the membrane first side adjacent at least a portion of the first layer of shingles second side. The second party attaches a second layer of shingles to the substrate, wherein the second layer of shingles is adjacent the membrane second side.

Abstract: Apparatus for use with a natural gas dehydrator wherein a portion of the wet glycol in an emissions separator is pumped under pressure as circulating wet glycol which may be used as a coolant for effluent removed from a reboiler and/or a power source for an eductor to form a vacuum in a first chamber of a liquid water removal separator apparatus. The cooled effluent, comprising at least liquid water, liquid hydrocarbons and uncondensed vapors, moves into the first chamber wherein the liquid water and/or the liquid hydrocarbons are separated from the uncondensed vapors. At least, the uncondensed vapors are removed from the first chamber and move into the eductor wherein they are compressed and combined into the circulating wet glycol. The separated liquid water is transferred to a second chamber of the liquid water removal separator apparatus and then removed therefrom. In some instances, the liquid hydrocarbons are transferred to a third chamber and removed therefrom.

Abstract: An electromagnetic peristaltic pump apparatus may comprise a main body section having an inlet end and an outlet end and a flexible membrane which divides the main body section into a first cavity and a second cavity. The first cavity is in fluid communication with the inlet and outlet ends of the main body section. The second cavity is not in fluid communication with the first cavity and contains an electrically conductive fluid. The second cavity includes a plurality of electrodes which are positioned within the second cavity generally adjacent the flexible membrane. A magnetic field generator produces a magnetic field having a plurality of flux lines at least some of which are contained within the second cavity of the main body section and which are oriented generally parallel to a flow direction in which a material flows between the inlet and outlet ends of the main body section.

Abstract: Apparatus for decurling a curled lid for a container wherein three decurling units are mounted on a base having an upstanding support wall wherein the first unit provides a partially decurled lid, the second unit provides a further decurled lid for performing a desired measurement and a third unit provides a substantially fully decurled lid for performing another desired measurement.

Abstract: A shim and method for using the same for adjusting camber and/or toe of a wheel assembly wherein first and second tapered annular shims are coupled together to permit relative rotation therebetween and each of the first and second tapered annular shims have visible indicia thereon. A chart is consulted to obtain an indicium on the first tapered annular shim that is to be aligned with an indicium on the second tapered annular shim so that the first and second tapered annular shims may be rotated to align the indicium on each shim so that the aligned indicia may be placed in the wheel assembly at a reference point on the wheel assembly to make the required camber and/or toe adjustments.

Abstract: A modular robot may comprise a main body having a structure defined by a plurality of stackable modules. The stackable modules may comprise a manifold, a valve module, and a control module. The manifold may comprise a top surface and a bottom surface having a plurality of fluid passages contained therein, at least one of the plurality of fluid passages terminating in a valve port located on the bottom surface of the manifold. The valve module is removably connected to the manifold and selectively fluidically connects the plurality of fluid passages contained in the manifold to a supply of pressurized fluid and to a vent. The control module is removably connected to the valve module and actuates the valve module to selectively control a flow of pressurized fluid through different ones of the plurality of fluid passages in the manifold. The manifold, valve module, and control module are mounted together in a sandwich-like manner and comprise a main body.

Abstract: A circuit for reversing a voltage polarity on a first electrode and a second electrode may comprise a first inductor connected between the first electrode and a negative terminal of an external power supply. The positive terminal of the power supply is connected to the second electrode. A diode and a first capacitor are connected in series across the first and second electrodes so that the cathode of the diode is connected to the first electrode. A second capacitor and a switching device are also connected in series across the first and second electrodes. A second inductor is connected between the switching device and the anode of the diode.

Abstract: A decorative wall formed from a plurality of modules wherein each module has a closed framework forming an opening in which a compost unit is located and wherein the closed framework has conduits located therein with couplings for permitting the passage of a fluid therethrough with at least one coupling of each module being connected to one coupling of another module and a soaker hose connected to one of the conduits to provide fluids to the compost unit.

Abstract: A treatment system for removing metal ions from water and a method for cleaning the system. Contaminated water is passed through a plurality of columns having ion-extracting agents therein. When saturated with ions, each column is successively cleaned with primary and secondary acid solutions from separate vessels. When the primary acid is saturated with ions, it is membrane-filtered to remove ions therefrom. The secondary acid is then directed into the primary acid vessel, with the purified primary acid being routed back into the system (preferably into the second vessel) for reuse. The column is then rinsed with water, washed with an alkali solution (periodically concentrated using a water-permeable membrane), and rinsed again with water. The system preferably uses three columns, all of which are successively cleaned in the manner described above.

Abstract: A device for holding a plurality of firearm cartridges having resilient portions to prevent movement, and therefore noise, of the firearm cartridges and having access openings to permit removal of a predetermined number of the firearm cartridges from a firearm cartridge removal section of the device and to permit the movement of the remaining firearm cartridges into the firearm cartridge removal section and wherein the resilient portions prevent movement, and therefore noise, of the remaining firearm cartridges.
