  • Publication number: 20150181863
    Abstract: An antibacterial cleaning composition for hard surfaces is made from a flexible superabsorbent material and an antibacterial agent. The composition can be applied to various liquid and solid surface contaminants, including blood, vomit, fecal matter, urine, glass, food, etc. The composition may be applied to the contaminated hard surface by several methods including pouring, rolling, spraying or foaming. Once cured, the antimicrobial cleaning composition is removed from the surface, taking the contaminant along with it and leaving behind a clean surface.

  • Publication number: 20060144776
    Abstract: A dialyzer header cleaning device composed of: a connecting member for connecting the device to the header, the connecting member having a longitudinal passage with a longitudinal axis; and a flow directing member having first and second opposed ends and a fluid passage extending between a fluid inlet at the first end and a fluid outlet at the second end. The flow directing member has a portion that extends from the second end toward the first end and is held in the longitudinal passage. The flow directing member is manually rotatable about the longitudinal axis relative to the connecting member and is manually movable along the longitudinal axis relative to the connecting member. The fluid outlet of the flow directing member is constructed to eject at least one liquid stream in a direction transverse to the longitudinal axis when fluid is supplied to the fluid inlet.

  • Publication number: 20060141074
    Abstract: Methods for neutralizing dust mite feces are disclosed. In one embodiment, a botanical extract having a BAPNA-Trypsin Inhibition (IC50×10?3 (%, v/v or w/v) of from about 0.01 to about 500 and a sufficient solubility in water is introduced into water to form an aqueous botanical extract solution. The aqueous botanical extract solution is atomized into an area being treated such that the botanical extract contacts and neutralizes the dust mite feces located in the area. Particularly preferred botanical extracts for use in the botanical extract aqueous solutions of the present invention include Green Tea Extra and Grape Seed Extract.

  • Publication number: 20050118237
    Abstract: Cleansing wipes comprising a film forming polymeric material and a cleansing agent stored in dry form are disclosed. The cleansing wipes are water disintegratable such that upon contact with water, the cleansing wipes release the cleansing agent and begin to dissolve/disperse into the water. Full dissolution/dispersion of the cleansing wipes occurs in about 60 seconds or less after contact with water to allow for a sufficient time for cleansing of the hands or other skin area.

  • Patent number: 6769190
    Abstract: An adjustable viewing frame (27) for use by artists to help compose a view comprises two frame members (10,11) each having two frame links (21,22,23,24) at right angles to one another. The frame links (21,22,23,24) have a rib (30) along one edge over which two C-shape clips (20) engage to hold the two frame members (10,11) together where they overlap. The force exerted by the clips (30) is sufficient to hold the two frame members (10,11) together against disturbances so that the frame (27) thus formed can be held in one hand for viewing purposes, but allows adjustments to be made easily by hand to change the size and/or relative proportions of the frame (27). A scale (40) marked on the frame member (10) allows specific relative proportions to be achieved with certainty and precision.
