摘要： An improvement in the manufacture of flexible densified polyurethane foam wherein the partially cured freely risen foam is fed through a crush conveyor to minimize the density gradient throughout the vertical cross section. The crush conveyor includes an upper crushing section which is arcuate and has a radius of a dimension such that the ratio of the radius of the arc to height of the partially cured freely risen foam is 1.1 to 1 or greater. The crush conveyor has a bottom crushing section which may be arcuate with a radius of a dimension such that the ratio of its radius to the height of the partially cured freely risen foam is also 1.1 to 1 or greater. The radius of the bottom arcuate crushing section may be the same or larger than the radius of the top arc. As an alternative, the bottom crushing section may be planar and may be horizontal, or inclined with respect to the horizontal.

摘要： 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.

摘要： 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.
