Abstract: A seamless drain system includes a sink basin having sidewalls and a bottom wall, and a seamless drain sidewall extending contiguously and below the bottom wall. The drain sidewall terminates in an attachment bayonet. The attachment bayonet includes an annular flange for removably coupling to a drainpipe adaptor or a disposal system. The sidewall includes a fluid line attachment stem for coupling a fluid line directly to the sidewall and drain. Accessories, such as a rubber splashguard or strainer basket, can be used in combination with a spray ring that nests within the drain sidewall and is in fluid communication with the fluid line, can be incorporated into the seamless drain system.

Abstract: A disposal system utilizing a direct injection of water for an amount of time to sufficiently sanitize a chamber of the disposal system. The disposal system includes a chamber coupled to a drain of a sink at a first end of the chamber, and to a drainpipe at a second end of the chamber. A cutting mechanism, such as a rotary cutting blade, is positioned within the chamber near a floor of the chamber. A fluid-injection unit, such as a flange attachment, coupled to the first end of the chamber and the drain of the sink, includes a plurality of nozzles for introducing a fluid in a variety of streams in different directions to reach substantially an entirety of the chamber. The flange attachment can also include a water line attachment for connecting to a water line, with an optional ozone generator upstream from the disposal system.

Abstract: A compact pump has a uni-body, or alternately a two-part, housing of self-skinning foam construction for superior noise and vibration reduction, such as needed for medical nebulizer applications. The uni-body foam housing is formed by molding the housing around a pump assembly having special features designed to shield and space apart moving or sensitive internal components of the pump assembly from the foam during the insert molding process. The alternate two-part foam housing is assembled using a union ring having multiple barbed pins that fit into openings in mating faces of the two housing sections.

Abstract: A pump (16) has a clamshell housing (12, 14) with walls (34, 36, 46, 50, 52) that come together and seal to create chambers (22, 24) which contain a pressure difference relative to ambient pressure.
