The peripheral lip forms a receptacle in the shelf for accommodating four support posts in a collapsed condition.

Abstract: A well water treatment system includes a first ozonation tank that receives pressurized well water and introduces ozone into that well water. The ozone causes impurities to precipitate, which settle to the sides and bottom of the first tank. Remaining water is delivered by gravity flow to a second supply tank wherein the ozone is allowed to largely if not entirely dissipate from the water. When a household or other destination requires treated water, a pump in the supply tank operates to deliver water from the tank to that destination. The pump is operably positioned within the supply tank at an intermediate water level below precipitates floating on the surface and above precipitates that have settled in the tank.

Abstract: An anchoring system for a boat includes a pair of anchor fixtures, each having a base and a tube carried by and extending across the base. A first of the anchor fixtures is mountable proximate the peripheral edge of the vessel with the tube oriented to extend in a generally horizontal direction. The other, second anchor fixture is mounted exteriorly to the transom of other surface of the hull such that the longitudinal axis of the tube extends generally vertically. The first anchor fixture accommodates an adjustable pole holder that has a stem for selectively engaging with the first anchor fixture to provide anchoring, transporting and stowed conditions. A sleeve is interconnected angularly to the stem for holding a first pole, which may be operated by adjusting the pole holder to engage the bottom of the body of water. A second pole is received by the tube of the second anchor fixture to likewise engage the bottom of the body of water such that the boat is anchored thereto.

Abstract: A peristaltic pump includes a support section and a rotor mounted for rotation on the support section. There are a pair of spaced apart cam elements attached to and extending from the rotor. A drive mechanism rotatably operates the rotor such that the cam elements are turned together with the rotor. There are first and second mounting sheaves connected to the support section. Each mounting sheave has a groove formed peripherally therein. An elongate, resilient tube conducts liquid therethrough. The tube includes leading and trailing tube segments and an intermediate tube segment formed longitudinally therebetween. The leading segment is retainably inserted in the groove of the first sheave and the trailing segment is retainably inserted in the groove of the second sheave to hold the intermediate segment of the tube for being operatively engaged by the cam elements as the rotor is operated.

Abstract: An inflatable laptop desk includes an inflatable base and a horizontal platform mounted to the base for supporting a laptop computer or other device. The base includes one or more valves that allow the base to be selectively inflated for mounting upon a user's lap and deflated for transportation and storage. An optional storage case may be incorporated into the desk.

Abstract: A centrifuge tube assembly includes an elongate tubular receptacle having a capped upper end. The capped upper end includes a single inlet/outlet port formed therethrough for communication with an interior of the tubular receptacle. A flexible aspiration pipe is communicably engaged with the inlet/outlet port for extending longitudinally through the cylindrical receptacle. A sealing diaphragm is attached to a distal end of the pipe. The diaphragm is longitudinally movable within the tubular receptacle and sealably interengages an interior wall of the receptacle. Biological products are introduced into and aspirated from the receptacle below the diaphragm by the fluid conducting pipe.

Abstract: A digital protractor for measuring angular displacement from a referenced surface includes a substantially congruent pair of pivotally interconnected upper and lower arms, which arms are superposable upon one another. Each arm has a pair of substantially parallel engagement edges extending longitudinally of the arm. One of the arms is engagable along an engagement edge thereof with the reference surface. A capacitive sensor is secured to the lower arm and a digital readout device is secured to the upper arm for operatively cooperating with the capacitive sensor to measure and display the angular displacement from the arm engaging the reference surface to the other arm.

Abstract: A secondary containment system for an above-ground petroleum storage tank includes a berm rising above the ground surrounding the tank and spaced apart from the tank for defining a petroleum retention basin about the tank. An impermeable liner covers the ground between the tank and the berm. At least one drain is formed through the liner and into the underlying ground. A hydrocarbon sensor monitors the presence of petroleum in the drain. A control device responds to the presence of petroleum in the drain by closing a containment valve to prevent discharge of petroleum from the basin. An indicator device provides at least one of an audible and visible signal indicating that petroleum is sensed in the drain.

Abstract: An ice gripping footwear attachment includes a base having an upper surface for engaging the bottom of the footwear and a lower surface carrying a grit material that is frictionally engagable with an ice covered surface. Forward, intermediate and rearward fastening straps are secured to the base. The forward strap is wrapped across the footwear such that it extends rearwardly in a crisscrossed pattern. The intermediate strap is wrapped and fastened over the forward strap. The rearward strap is then secured across the wearer's ankle or heel to securely fasten the attachment to the footwear.

Abstract: A liquid refill control for a holding tank includes a pneumatic solenoid valve for delivering liquid to the tank in an open state and restricting delivery of the liquid to the tank in a closed state. The solenoid valve has a pneumatic exhaust. A container mounted in the tank includes an inlet for introducing liquid from the tank into the container and an outlet formed below the inlet. A discharge valve is operably mounted to the tank for alternately closing and opening the outlet. A lower float closes the discharge valve when the liquid is at or above a predetermined level in the tank and opens the discharge valve when the liquid is below the predetermined level to discharge liquid from the container. A pneumatic exhaust valve alternately opens and closes the pneumatic exhaust which in turn changes the state of the pneumatic solenoid valve.
