  • Patent number: 6390291
    Abstract: A method and package for storing a pressurized container which is filled with a drug formulation at a predetermined pressure. The drug formulation includes a mixture of a drug and a propellant. The package which encloses the pressurized container substantially prevents ingression of water vapor and particulate matter into the package while permitting egression of the propellant which may leak from the pressurized container.

  • Patent number: 6065472
    Abstract: A powder inhalation device comprising a housing containing a pharmacologically active compound, a conduit (8) with an outlet extending into the housing through which a user can inhale to create an airflow through the conduit, a dosing unit (6,7) for delivering a dose of the compound to the conduit and baffles (9) arranged within the said conduit to aid disintegration of powder agglomerates entrained in said airflow. The baffles (9) comprise a plurality of staggered plates extending into the conduit from opposite sides of the conduit at an angle of less than 90.degree. to the sides of the conduit and are inclined towards the outlet to create a plurality of constrictions within the conduit and a plurality of changes in the direction of the said airflow through the conduit.

  • Patent number: 5803152
    Abstract: The present invention relates to eutectic alloy systems, such as white irons, in which a primary phase grows out of the melt when the melt is cooled below the liquidus temperature and comprises pouring the molten metal alloy at a temperature at or above the liquidus in a stream into a casting mould to form a casting and introducing a particulate material into the stream of molten metal to extract heat from the molten metal alloy to undercool the molten metal alloy from the pour temperature into the primary phase solidification range between the liquidus and the solidus temperatures of the alloy and thereby initiate primary phase nucleation and restrict primary phase growth. The primary function of the particulate material is to act as a heat sink but the particulate material may at least partially dissolve in the melt and may act as a seeding agent for the primary phase. The invention is described with particular reference to high chromium hypereutectic white irons.
