  • Patent number: 6565818
    Abstract: A recycling system melts unused portions of soap in order to improve the efficiency of the soaking procedure. A chamber has a pump and a screen that holds the soap disposed therein, while a tube member connects to the chamber. One or two conduits are fluid flow connected to the outlet port of the pump and each have one or more jets that protrude through the tube member. Soap is placed onto the screen and water is drawn into the chamber by the pump. The inlet pattern of the pump creates a flow of water that flows over the soap on the screen, with the soap laden water being pumped through the conduits and discharged into the sink by the jets. Now that the soap has melted into soap laden water, pieces and bits of soap will not stick to the fabric at the conclusion of the soak wash period. A fluid level switch deactivates the pump if the water within the sink falls below a certain level.

  • Patent number: 6562302
    Abstract: An incense tray for use with sticks of incense that has a base with an inner surface to receive incense ashes and a housing mounted on the base that has top portion with a screen that permits air to flow from the inside to the outside of the housing. The tray further includes a plurality of incense holders spaced around the periphery of the housing that are angled inwardly towards the center of the tray so that the incense sticks they receive also angle inwardly towards the center. A fan is mounted within the housing to direct the flow of air upwardly through openings in the screen so that the incense smoke is drawn toward the center and then upwardly. A receptacle for receiving a fragrant votive candle or fragrant oil can be mounted on the screen to improve and complement the aromatic effect of the incense smoke.

  • Patent number: 6555054
    Abstract: A flow-through rack assembly (14) includes porous hangers (44) which support items to be decontaminated within a decontamination chamber (12). A plurality of nozzles (16) spray a decontaminant fluid, such as peracetic acid, over the items. The rack assembly includes tubes (42) which convey a portion of the decontaminant fluid under pressure to internal channels (52) of the porous hangers. The fluid permeates the hanger surface, flowing over regions of the items which are in contact with the hangers. The rack assembly ensures decontamination of those regions which may be otherwise inaccessible to fluid sprayed from the nozzles.

  • Patent number: 6537492
    Abstract: The surface of items which are penetratable for high-frequency energy, like for instance plastic food packagings which are manufactured by blow molding or vacuum molding, and in particular returnable bottles for soft drinks, are sterilized by providing a liquid film on the items, following which they are subjected to microwaves or high-frequency to heat the liquid film, preferably to the boiling point. The liquid is preferably water with a de-tensioning agent. An apparatus for performing the method is provided with wetting means, dripping off means adapted to leave a liquid film on the items during the dripping off, and heating means. The dripping off means are substantially constituted by transport means for conveying the items from the wetting means to the heating means. A system for sterilizing plastic bottles may compromise a washing section, a rinsing section, transport means adapted to let the bottles drip off during transport, and a heating section.

  • Patent number: 6500394
    Abstract: A dry sterilizer includes a container for containing beads, a heater, and a resilient member disposed adjacent to an opening of the container. An instrument, after sterilization, is tapped against the resilient member to remove beads attached to and lodged in the instrument and the removed beads are returned to the container. The resilient member prevents beads from entering a housing of the sterilizer by blocking a gap between the container and the housing at the opening.

  • Patent number: 6475431
    Abstract: A low toxic, biodegradable, water soluble and dispersant series of corrosion inhibitors are described. The method of inhibiting corrosion in aqueous medium by incorporating the inhibitor in PPM is provided. The corrosion inhibitor compromises an acrylic acid and chloroacetic acid adduct of 2-substituted imidazolines or primary, secondary or tertiary amines with carbon chain of twelve to twenty-two saturated or unsaturated carbon atoms. The molar ratio of acrylic acid to chloroacetic acid was methodically changed while keeping the concentration of imidazoline or the amine a constant. The product is made water soluble by raising the pH to 8-9 at the end of the synthesis by adding aqueous sodium hydroxide.
