Abstract: Disclosed are trichloroisocyanuric acid compositions that have improved algicidal and/or fungicidal properties yet are relatively safe and non-corrosive. The compositions preferably contain between about 50% and about 95% TCCA, between about 0.5% and about 7% glycoluril, between about 2% and about 40% alum, and between about 2% and about 40% borax. The compositions generate substantially less chlorine gas than would be expected from the teachings of the prior art, especially when wet. The inventive compositions are therefore less toxic and less corrosive.

Abstract: A multi-function stalk switch that incorporates a pushbutton switch, a first rotary switch and a second rotary switch onto the end of a stalk, wherein further switching functions may be executed by moving the entire stalk in either of two orthogonal planes. The stalk switch incorporates many design features that enable it to be assembled at low cost from a small number of parts. One such feature is the use of plastic-on-plastic detents to control positioning of the rotary switches so that they wipe across predetermined portions of a flexible printed circuit board. Another feature is the inclusion of a spring-loaded plunger detent riding in a concave centering mechanism that is operable to automatically return the stalk switch to its central (neutral) position after removal of external biasing forces. A further feature is the inclusion of magnets on the stalk switch and Hall effect sensors fixedly mounted nearby in order to sense movement of the magnets (and therefore the stalk) in two orthogonal planes.

Abstract: An assembly for tanning in which a canopy containing both a source of fluorescent tanning lamps and electronic ballasts is attached to and able to rotate about the upper end of a pivoting arm. The lower end of the pivoting arm is inserted within and able to rotate about a leg of a base which is in the shape of a dog leg, the bend being in the plane of rotation of the pivoting arm. A counterbalancing member is attached to both the base and to the pivoting arm near the dog leg bend. The planes of rotation of both the pivoting arm and the counterbalancing member lie on the closed side of the "U" shape of the base. The pivoting arm may be rotated about its connection to the base, such that the entire assembly is placed in a compressed condition. In this compressed condition, a strap attached to either the canopy or pivoting arm can be attached to the base to maintain the assembly in the compressed condition during transport and storage.
