Granted: 1994-04-05
Abstract: ABSTRACT           In a connector (or adaptor) that acts as a conduit for the filtration of fluids from a monitor, in microbiological analysis, plastic multi-purpose adaptors are generally used. In this invention the adaptor/connector is milled from a solid piece of stainless steel and features a circular flange and a male leur tip.  The connector is then bored to create a straight bore channel.  The connector is designed to allow filtration through the membrane filter in the monitor at a much faster rate than the traditional plastic adaptors.  The one piece construction and ease of sterilization reduces the possibility of the bacterial growth that may adversely affect microbiological results.

Granted: 1997-05-27
Abstract: A method of forming high temperature resistant coatings from a quantity of composite particles, each comprising very small magnetic particles in a ceramic matrix by plasma spraying the composite particles onto a surface. Typically, the surface to be coated is pre-treated by a combination of solvent cleaning and abrasion, such as by- grit blasting. In some cases the surface is coated with a thin electrically conductive transition layer having a coefficient of thermal expansion intermediate those of the surface and the composite coating. A quantity of finely divided composite particles are then prepared, each of the particles comprising a ceramic matrix containing plural spaced very small magnetic metal particles. In some cases, a small quantity of smaller pure matrix particles or lower melting particles are mixed with the composite particles to improve bonding. The composite particles are plasma sprayed onto the surface to be coated at temperatures such that only the surfaces of the composite particles are melted, thereby permitting higher magnetic material loadings without forming an excessively electrically conductive coating. The resulting coating is durable, has high temperature resistance and absorbs incident microwave energy.
