Abstract: According to an aspect, an electrochemical cell may include a vessel, at least two instances of an anode assembly, at least two instances of an oxygen evolution electrode (OEE), and a gas diffusion electrode (GDE). In the vessel, the GDE may be disposed between mirrored arrangements of the at least two instances of the OEE and the at least two instances of the anode assembly.

Abstract: A hanger support for use in association with a strut channel or with truss or joists formed from pairs of angle irons includes a stem and arms extending outward from the stem with a hole extending through the stem to receive a threaded rod or bolt. The hanger support is sized to pass lengthwise through the gap between pairs of angle irons of the truss and then rotated ninety degrees so that the arms are supported on the angle irons with the threaded rod or bolt extending through the gap and below the angle irons to support a hanger. The stem is also sized to fit in the space between shoulders of a strut channel. A second embodiment includes a lip depending from one of the arms to form a groove between the lip and stem with a set screw secured within a threaded bore in the lip.

Abstract: A method and apparatus for removing the sulfation from the plates of the battery and driving the sulfate crystals back into the electrolyte solution without overheating the battery is presented. The present invention includes a rotary magnetic hub and coil assembly to produces a unique output not found in other charging systems on the market. The battery desulfation method and apparatus of the present invention is self-adjusting to the battery, regardless of voltage and works by removing the sulfate crystals from the plates of lead acid batteries. As a result, the normal life of the average battery may be greatly extended. Heavily sulfated batteries may be brought back to working condition. When used for short durations for healthy batteries, the present invention keeps the sulfate crystals off the plates and in solution to extend the working life of the battery.

Abstract: A hanger support system that provides for attachment and suspension of materials from an elongated support structure such as an angle iron truss. The system includes a hanger support having a main body with means for attaching items to the hanger support, and an elongated tongue projecting upward from the main body to form a hook for hanging the hanger support upon the support structure. The hanger support further includes gussets projecting upward from the main body to engage the tongue and various bores in the main body for accepting threaded rod, or the shanks of bolts, to attach items to be suspended from the support structure.

Abstract: A lap stand for supporting a craft frame or hoop upon a user's lap such that the hoop may be swiveled upon a universal joint in a variety of orientations to allow improved user access to the work piece held by the hoop.

Abstract: An improved craft hoop stand comprises two different sized craft hoop sets removably secured together in spaced apart relation by a plurality of rods whose ends are removably securable within holes extending into bosses extending inwardly from an inner ring of each craft hoop set. The stand is adapted for selectively supporting one of the craft hoop sets above a surface such as the lap of a user. The craft hoop sets are removably securable together such that the hoops may be used separately.

Abstract: A craft hoop assembly for securing material on which a craft is to be performed comprises an inner hoop or ring having an outer surface and a split outer hoop or ring having an inner surface which is positionable in circumscribing alignment with the inner ring such that the inner surface of the outer ring generally abuts against the outer surface of the inner ring. A bead is integrally formed on either the inner surface of the outer ring or the outer surface of the inner ring. A corresponding groove is formed in the opposing surface of the inner or outer ring respectively. Projections, ridges or bumps are integrally formed on the inner surface of the outer ring or the outer surface of the inner ring or both to increase the gripping effect of the rings on fabric secured therebetween. The projections are preferably formed on said bead. The projections may be randomly arranged or arranged in specific patterns to enhance the gripping effect.
