Three dimensional periodic chart support and container

A method for producing sanitizing compositions in compressed form which includes:

Effervescent tablets having increased disintegration rates

A pool chemical dispenser utilizing a flotation device to hold the dispenser on the surface of a body of water such as a swimming pool and a pool chemical-containing cartridge that fits within the flotation device is provided. The cartridge is intended to hold a fast dissolving pool chemical, such as calcium hypochlorite, and is equipped with a cartridge skirt and a cartridge skirt insert with a pool chemical tablet support grid to ensure partial immersion of the pool chemical tablet closest to the water.

Pool chemical dispenser

An improved chemical feeder employing periodic partial immersion in a forced circulation system is provided having a soluble chemical chamber, a dissolving chamber into which the soluble chemical chamber extends and a discharge chamber in fluid flow communication with the dissolving chamber to selectively receive chemically treated water from the dissolving chamber and discharge it into a flow loop connected to the forced circulation system.

Pool chemical dispenser cartridge

A pool chemical dispenser is provided that comprises a rotatably adjustable top, a container and a ballast disk cooperative with the top such that the specific gravity of the material of the top and the container is less than 1.0 and the specific gravity of the material of the ballast disk is greater than 1.0 thereby permitting the dispenser to float off the bottom of the skimmer in which it is immersed in water when less than about 10% of the pool chemical remains in the container and invert, remaining on the top of the surface of the water to indicate the pool chemical is exhausted.

Swimming pool chemical dispenser

This invention is directed to a fastener for securely joining two or more abutting flat panels together along their edges without the necessity of piercing any of the panels or disassembling the connection assembly. The fastener comprises first and second directionally oriented compressible parts of resilient material which are pressed against opposing sides of the panels and means for applying a mechanical force to produce said pressing action causing a partial shape change of the opposing frustoconical compressible parts. The force applying means comprises an elongated threaded member and a body portion extending through an aperture in each compressible part with a wing nut mounted on the extending ends thereof to anchor the parts together. Due to their particular shape, orientation and gripping properties, the compressible parts transfer a large portion of the pressure applied on the opposing exterior sides of the compressible members to directions parallel to the planar surface to firmly join the edge of one panel against the edge of the other panel in the case of edge to edge flush joining, or in a single direction designed for support of the panels by the fastener.

In-pressing planar edge joiner clamp

Swimming pool chemical dispenser or the like

A novel package of available chlorine compound comprised of a stack of a plurality of tablets enclosed in a liquid impervious synthetic material. The package is prepared by placing the stack of tablets in a tube of heat shrinkable synthetic material and then heating to effect shrinkage and to form a tightly adhering tube of synthetic material around the cylindrical exterior of the tablets. The resulting package can be adjusted to size by cutting where desired between tablets. The packages are useful in sanitizing water, particularly swimming pool water by placing them in a strainer basket of a skimmer unit.

Novel package for water sanitizing chemical and method for preparing it

A prepolymer of a polymeric isocyanate and a halogenated polyol is used in generating polyurethane foam by means of a portable foaming apparatus. Such prepolymers retain the frothing agent adequately, have improved stability and exhibit practically no crystallization or viscosity increase on storage.
