Abstract:

An in-vitro diagnostic method is provided for detecting acetylsalicylic acid ingestion by a patient by utilizing radioimmunoassay procedure. The method comprises the steps of: derivatizing acetylsalicylic acid with a protein moiety being effected in a molar ratio of about one mole of protein to at least thirty moles of acetylsalicylic acid; coupling the acetylsalicylic acid derivatized protein with a water insoluble solid matrix by binding with a selected chemical agent; obtaining a sample of patient serum; freeze drying the serum including any antibodies specific to acetylsalicylic acid to concentrate the serum to a solid phase; diluting the freeze dried serum to from about 100 to about 1,000 times its original concentration; incubating the solid matrix coupled with the acetylsalicylic acid derivatized protein with the concentrated serum for a sufficient period of time to allow any antibodies specific to acetylsalicylic acid to attach to the solid matrix coupled with the acetylsalicylic acid derivatized protein, the incubation occurring for at least 24 hours at a temperature range of from about 4. degree. C. to about 42. degree. C. ; thereafter, incubating the solid phase bound with specific antibodies present with radioactively labelled antibodies specific to acetylsalicylic acid derivatized protein obtained from a test animal for a sufficient period of time to allow binding between the labelled antibodies and the matrix; separating the mixture into distinct liquid and solid phases; and measuring the radiation emitted from at least one of the separated phases.

Abstract:

A seal ring system is provided. The seal ring system comprises a segment defining a slot, a pedal along the slot, and an opening offset from the slot. A retention fastener may be disposed in the opening. A seal ring system is also provided comprising a first segment defining a first opening, a second segment defining a second opening, and a retention fastener extending through the first and second openings. The retention fastener configured to allow relative radial movement of the first segment and the second segment. A seal is further provided comprising a seal ring having a central axis, a petal extending radially inward with respect to the central axis of the seal ring, and a sealing disk axially proximate the seal ring. The sealing disk may have a seal shoe configured as a primary seal. The petal may extend toward the seal shoe.

Abstract:

A seal support structure is provided for a circumferential seal. In one embodiment, the seal support structure includes an engine support structure, a seal support, and a shoulder joining the engine support and seal support. The shoulder offsets the engine support from the seal support, and the shoulder and the seal support structure are configured to dampen vibration for the circumferential seal. The seal support structure may employ one or more dampening elements or materials to interoperate with a seal support structure to dampen vibration to a seal system.
