Abstract: An ice cube maker having modules to mass produce high quality transparent ice cubes comprising an agitation system and a refrigeration system utilizing at least substantially one directional freezing of the water through a wall of an ice mold to make an ice cube having a center that is void of visible crystallization and void of a visible bubble with no visible cracking therein.

Abstract: An embodiment of the present invention is a transparent ice cube maker configured to mass produce transparent ice cubes comprising various water movement systems and various refrigeration systems utilizing at least substantially one directional freezing of the water through a wall of an ice mold to make an ice cube having a center that is void of visible crystallization and void of a visible bubble.

Abstract: A safety cover having a filter and an optional chemical dispenser, that covers and existing faceplate on a water vessel having a closed loop piping system and water pump. When the cover and filter cover an existing faceplate the cover and filter increases the vacuum on a suction line leading to a water pump by less than 5? Hg. The chemical in the dispenser releases in a metered dose of a substance having antimicrobial properties and the dose is in a sufficient amount to inhibit a growth of a microorganism in at least a segment of a water vessel. The combination of cover, filter and chemical chamber are disposable, or the filter is replaceable and the chemical in the chemical chamber is replenishable. The cover with filter and chemical chamber or just the cover and chemical chamber, or just the cover and filter are retrofitable to any existing faceplate on a water vessel having a closed looped piping system and a water pump.

Abstract: A fill and drain hydromassage water vessel having an acrylic surface, resin and fiberglass backing and antimicrobial in components of the water vessel system. The antimicrobial reduces bacteria in the water vessel system.

Abstract: A fill and drain jetted hydromassage whirlpool bathtub having a tub made of acrylic, resin and fiberglass. The whirlpool bathtub having a water system with drain down water features and components made of a material having an antimicrobial therein. Bacteria reduction occurs in the water vessel system where the antimicrobial is therein. The non-porous acrylic surface, the drain down features and the antimicrobial surfaces provide an economic sanitation level for hydromassage jetted whirlpool bathtub.

Abstract: A method to make a whirlpool bathtub where bacteria growth is inhibited or bacteria is reduced, after tub drain down and between electrical system activation.

Abstract: A device and method to inhibit bacteria in a whirlpool bathtub and its closed looped plumbing system between each whirlpool bathtub drain down as well as during each whirlpool bathtub use. In addition to combining a high flow antimicrobial chamber with a suction device, the present invention incorporates safety features.

Abstract: A whirlpool bath has a combination suction fixture and filter in the form of a porous faceplate.

Abstract: A system to sanitize water in a whirlpool bathtub, spa, swimming pool, and other water vessels comprising incorporating an antimicrobial agent in some or all segments of the piping of the closed loop water system and/or the air piping.

Abstract: A system to sanitize water in a whirlpool bathtub, spa, swimming pool, and other water vessels comprising improvements to U.S. Pat. No. 6,395,167 and incorporating an antimicrobial chemical dispenser.

Abstract: A system to sanitize water in a whirlpool bathtub, spa, swimming pool, and other water vessels comprising improvements to U.S. Pat. No. 6,395,167 and incorporating an antimicrobial chemical dispenser.

Abstract: A system to sanitize water in a whirlpool bathtub, spa, swimming pool, and other water vessels comprising improvements to U.S. Pat. No. 6,395,167 and incorporating an integral top fill antimicrobial injector not in the prior art. The system also practices the adding of antimicrobial additives to the water vessel system components, which include but are not limited to the system's piping, pump, jets, acrylic sheet and fiberglass/resin reinforcements.

Abstract: A whirlpool bath has a combination suction fixture and disposable filter. The suction fixture is a plastic semi-cylindrical housing attachable to the tub. A removable faceplate is reinforced and resistant to body and hair entrapment. The disposable filter is fibrous having a porous core, wherein the porous core has a series of holes and/or slots graduating in size from small at the outlet end to large at the remote end. The filter, sloped floor of the housing and drain slots provide for low water retention during shutdown. A safety/sanitation port on the outlet port creates cavitation if the whirlpool bath is operated without the disposable filter. The preferred embodiment removable faceplate is attached to the housing via a magnet and a peripheral ledge providing a pop off design. The preferred embodiment filter also has a pop off design.
