  • Patent number: 6114273
    Abstract: An improved process is provided for the removal of sulfur oxides from gas or vapor media containing oxygen and H.sub.2 O by contacting the media with a catalytically-active carbonaceous char. The improvement is provided by the use of a catalytically-active carbonaceous char prepared by low-temperature carbonization and oxidation of a bituminous coal or bituminous material at temperatures below 700.degree. C., followed by contact of the carbonized, oxidized char with one or more nitrogen-containing compounds at a temperature which is stable at, or is increasing to, temperatures less than 700.degree. C., and then increasing the temperature of the resultant material to or above 700.degree. C.

  • Patent number: 6000198
    Abstract: A package and method for the packaging of contents at a reduced pressure which provides for improved protection of said materials from contamination. The method includes hermetically sealing a gas and vapor impermeable packaging containing both the material, object, and/or device and an adsorbent at elevated temperature. Subsequent cooling of the adsorbent results in the production of a partial vacuum within the packaging. Alternatively, if the packaging is evacuated prior to sealing by use of some mechanical device, the subsequent cooling of the adsorbent results in a further reduction of the interior pressure of the packaging. The improvement is provided by the presence of the cooled adsorbent in the packaging. Due to the presence of the cooled adsorbent within the packaging, the vacuum within the packaging is produced or increased and more readily maintained due to the adsorptive action of the adsorbent.

  • Patent number: 5977252
    Abstract: Described herein is a technique for covalently modifying tissue and cellular surfaces to inhibit cell adhesion. The process described herein is conducted under conditions tolerable in vivo and employs a biocompatible polymer having a reactive group attached to at least one end that reacts with groups present or on tissue and cellular surfaces under aqueous and mild conditions and thereby covalently attaches the polymer to the tissue or cellular surface. Preferably, the reactive group attached to the polymer reacts with amines and hydroxyls present on tissue and cellular surfaces. In one preferred embodiment, the methods described herein provide for the covalent modification of tissue and cellular surfaces using a PEG-diisocyanate solution. The methods described herein are particularly useful in impairing platelet and leukocyte deposition in blood vessels and thereby thwarting thrombosis and restenosis, a common complication of vascular procedures including PTCA and vascular surgery.

  • Patent number: 5957119
    Abstract: A pneumatic valve and regulator, and more particularly to a pneumatic valve and regulator used in a compressed gas powered gun system which is designed to project a fragile liquid-containing spherical unit which bursts upon impact with the intended target. The regulator possesses a pressure balancing device, a temperature compensating device, and relief valve features. The temperature compensator of the temperature compensating device is made of a synthetic compound material which expands and contracts at a rate that equals but is inverse to the rate of change caused by changes in the modulus of elasticity of a helical compression spring caused by a temperature differential. The valve possesses a seal made of pressure-activated material, the outer diameter of the seal is mechanically captured, the inner diameter of the seal is not constrained from moving into the cavity.

  • Patent number: 5925014
    Abstract: The present invention relates to a method of preparing and administering one or more drug solutions for continuous infusion. Flow rates are standardized by varying the drug concentrations according to a preestablished set of tables. The method of the present invention greatly simplifies clinical application of continuous infusion anesthesia, and allows easy preparation of different volumes which can minimize drug wastage. The standardization of rate taught by the present method eases interpretation and mixing, resulting in easier application of drugs and increased patient safety. An apparatus is desirably used to assist in achieving the objectives of the present invention. The device facilitates accurate and efficient conversion to the nonstandard flow rates required for special applications such as neonatal anesthesia and others.

  • Patent number: 5876607
    Abstract: Treatment of a wet activated carbon with carbon dioxide or with carbon dioxide followed by air results in a carbon having a reduced contact pH. The activated carbon is characterized by a modified contact pH less than about 9.0 and typically between about 7.3 and 9.0. Use of this carbon in a water treatment system eliminates the excessive effluent water pH rise which commonly occurs with activated carbon. Also use of this carbon in a water treatment system reduces the aluminum concentration of the water when compared to an untreated carbon.
