20090293279 | METHOD OF MAKING ELECTRET ARTICLES BASED ON ZETA POTENTIAL - A method of making an electret article, from a polymeric article that has a zeta potential of greater than or less than −7.5 millivolts. The article is charged by contacting it with an aqueous liquid that has a pH and conductivity as follows: (i) if the article has a zeta potential of −7.5 mV or less, then the contacting liquid has pH greater than 7 and a conductivity of 5 to 9,000 microSiemens per centimeter; and (ii) if the article has a zeta potential of greater than −7.5 mV, then the contacting liquid has a pH of 7 or less and a conductivity of 5 to 5,500 microSiemens per centimeter. An electret article made in this manner can provide improved electret performance, particularly in electret filtration articles. | 12-03-2009 |
20110041471 | ELECTRET WEBS WITH CHARGE-ENHANCING ADDITIVES - Electret webs are presented which include a blend of a thermoplastic resin and a charge additive. The charge additives include ester-substituted and amide-substituted trianilino triazine materials. The webs prepared from the blends may be in the form of films or non-woven fibrous webs. Non-woven microfiber webs are useful as filtration media. | 02-24-2011 |
20120017910 | ELECTRET WEBS WITH CHARGE-ENHANCING ADDITIVES - Electret webs are presented which include a blend of a thermoplastic resin and a charge-enhancing additive. The charge-enhancing additives include a heterocyclic imide material which is free of fluorinated groups. The webs prepared from the blends may be in the form of films or non-woven fibrous webs. Non-woven microfiber webs are useful as filtration media. | 01-26-2012 |

20090032423 | ANTIMICROBIAL MEDICAL WASTE DISPOSAL ENCLOSURES - An enclosure configured to receive and secure a medical waste container. The enclosure comprises a main body and a cover. The cover is connected to the main body and configured to be moved between an opened position and a closed position. An antimicrobial agent is provided along the inside and outside surfaces of the main body and along the inside and outside surfaces of the cover to inhibit growth of bacteria and the like. | 02-05-2009 |
20090120821 | DISPOSABLE CONTAINER SYSTEM AND METHOD WITH REUSABLE HOOD ASSEMBLY - A kit for medical waste disposal comprising a plurality of containers; a hood assembly configured to substantially cover an open end of a respective one said containers, the hood assembly defining a passage through which medical waste can be passed to the open end of said container; and a plurality of lids, separate from the hood assembly, each configured to be placed over an open end of a respective container and to substantially close the open end of said container when said container is at least partially filled with medical waste; each of said containers being configured for separation from the hood assembly for disposal. | 05-14-2009 |
20090145901 | Medical Waste Disposal System - A container system is provided with a container having a door mounted for pivotal reciprocation about a door pivot axis between opened and closed positions. The container system also has a carrier with a body receiving the container and an arm coupled to the body for pivotal reciprocation about an arm pivot axis that is oriented substantially parallel to the door pivot axis. The arm engages the door of the container, and the pivotal reciprocation of the arm reciprocates the door of the container between the opened and closed positions. | 06-11-2009 |
20110253716 | Medical Waste Disposal System - A method of medical waste disposal comprising (a) positioning an open end of a container relative to a hood assembly such that the hood assembly substantially covers the open end of the container; (b) depositing medical waste in the container through a passage defined by the hood assembly until the container is at least partially full; (c) placing a lid over the open end of the container such that the open end is substantially closed; (d) disposing of the container; (e) sterilizing the hood assembly; and (f) repeating step (a). | 10-20-2011 |

20090100661 | Apparatus and Method for Unwinding A Needle Portion - A container system is provided for removing a needle portion from a needle holder of a needle system. The system includes a receptacle defining an opening, a lid configured to cover the receptacle opening, wherein the lid defines an aperture having a shape configured to receive a needle system having a first configuration. The system also includes an adapter configured for engagement in the lid aperture, wherein the adapter defines an aperture having a shape configured to receive a needle system having a second configuration, and wherein the engagement of the adapter in the lid aperture resists rotation of the adapter with respect to the lid. | 04-23-2009 |
20110100850 | Apparatus and Method for Unwinding a Needle Portion - A container system is provided for removing a needle portion from a needle holder of a needle system. The system includes a receptacle defining an opening, a lid configured to cover the receptacle opening, wherein the lid defines an aperture having a shape configured to receive a needle system having a first configuration. The system also includes an adapter configured for engagement in the lid aperture, wherein the adapter defines an aperture having a shape configured to receive a needle system having a second configuration, and wherein the engagement of the adapter in the lid aperture resists rotation of the adapter with respect to the lid. | 05-05-2011 |

20130048660 | WASTE CONTAINER ASSEMBLY - A container for disposing of waste includes a receptacle and a first pivoting member functionally associated with the receptacle. The first pivoting member includes a first disposal surface. A second pivoting member functionally associated with the receptacle includes a second disposal surface. The second pivoting member is operatively coupled to the first pivoting member such that waste deposited on either the first disposal surface or the second disposal surface causes concurrent counter rotation of both the first pivoting member and the second pivoting member to dispose of the waste into the receptacle. | 02-28-2013 |
20150034665 | WASTE CONTAINER ASSEMBLY - A container for disposing of waste includes a receptacle, a first pivoting member having a first disposal surface and a first pair of opposing sides, and a second pivoting member having a second disposal surface and a second pair of opposing sides. The second pair of opposing sides are operatively coupled to the first pair of opposing sides such that waste deposited on either the first disposal surface or the second disposal surface causes concurrent counter rotation of both the first pivoting member and the second pivoting member. The first pivoting member includes a pair of opposing projections secured in a stationary position to the first pair of opposing sides and the second pivoting member includes a pair of opposing apertures formed in a stationary position in the second pair of opposing sides. The opposing projections translate within the opposing apertures during the concurrent counter rotation. | 02-05-2015 |
