Title: Desulfurization process and novel bimetallic sorbent systems for same.
Inventor: GYANESH P KHARE
IPC: B01J20/34
Filed: 2000-12-11
Abstract: Novel sorbent systems for the desulfurization of cracked gasoline are provided which are comprised of a bimetallic promotor on a particulate support such as that formed of zinc oxide and an inorganic or organic carrier. Such bimetallic promotors are formed of at least two metals of the group consisting of nickel, cobalt, iron, manganese, copper, zinc, molydenum, tungsten, silver, tin , antimony and vanadium with the valence of same being reduced, preferably to zero. Processes for the production of such sorbents are provided wherein the sorbent is prepared from impregnated particulate supports or admixed to the support composite prior to particulation, drying, and calcination. Further disclosed is the use of such novel sorbents in the desulfurization of cracked gazoline whereby there is achieved not only removal of sulfur but also an increase in the olefin retention in the desulfurized product. Such sorbents can also be utilized for the treatment of other sulfur containing streams such as diesel fuels.

Title: Method and apparatus for ozone sterilization.
Inventor: RICHARD TURCOT
IPC: A61L2/24
Filed: 2002-11-08
Abstract: The sterilization method disclosed includes the steps of providing a sterilization chamber (10); - placing the article into the sterilization chamber; - equalizing the temperature of the article and the sterilization atmosphere; sealing the sterilization chamber; -applying a vacuum (40) of a preselected vacuum pressure to the sterilization chamber; - supplying water vapour (30) to the sterilization chamber under vacuum; - supplying ozone-containing gas (22) to the sterilization chamber; - maintaining the sterilization chamber sealed for a preselected treatment period; and - releasing the vacuum in the sterilization chamber; whereby a vacuum pressure is used which lowers the boiling temperature of water in the sterilization chamber below the temperature in the sterilization chamber. One or more ventilating cycles can be added to the preferred method for removing the remaining ozone and humidity from the sterilization chamber. Single cycle sterilization with ozone is more efficient and provides for a shorter sterilization cycle than with ETO and requires few changes in user habits. Moreover, the ozone-based process in accordance with the invention is compatible for use with current packaging, such as sterile pouches and rigid containers. The sterilization process is simple and substantially avoids human errors caused by false interpretation and handling. The ozone sterilization method of the invention requires substantially no aeration or cooling down of sterilized instruments so that they can be used immediately following the sterilization cycle. This allows hospitals to reduce the cost of maintaining expensive medical device inventories.

Abstract: An aerosolization apparatus (100) comprises a body (105) having an inlet (130), an endpiece (110) having an outlet (125), the endpiece being connectable to the body to define a chamber, wherein the chamber (115) is sized to receive a capsule containing a pharmaceutical formulation in a manner which allows the capsule to move within the chamber. The apparatus further includes a connection mechanism (150) to provide selective connection of the endpiece to the body, wherein a rotational force between the endpiece and the body is needed to connect or disconnect the endpiece from the body, the rotational force being applied about an axis passing through the chamber. When a user inhales, air enters into the chamber through the inlet so that the pharmaceutical formulation is aerosolized within the chamber and the aerosolized pharmaceutical formulation is delivered to the user through the outlet. The connection mechanism prevents inadvertent disconnection of the endpiece from the body.
