    摘要: Magnetic means and apparatus for implementing rail bonds and rail feeds. A rail bond embodiment comprises an electrical conductor. Mechanically and electrically coupled to each end of the electrical conductor is a magnet that comprises a magnetic material that is plated with an electrically conductive material. In an alternative embodiment, the magnet comprises a magnetic material that is disposed between two pieces of steel or other metal. In operation, the two magnets are attached to two rail sections, across a joint separating the rails, via the attractive magnetic force between each magnet and its associated rail. In this way, the electrical circuit comprising the rails is maintained.

    摘要: A method and system for in vivo dermal absorption testing of a laboratory animal uses a mask and harness for protecting the respiratory tract of the animal when the animal housed within a sealed chamber with a hazardous test vapor introduced in the chamber. Because of the difficulty of getting a good seal with a protective mask on a laboratory animal, this system is designed with an air leak from inside the mask into the chamber. To ensure that the test vapor does not infiltrate the mask nor leak from the chamber, the vapor is maintained at a negative pressure within the chamber as compared to the external atmospheric pressure and air is supplied to the mask for the animal to breathe at a positive pressure and at a greater rate than that needed by the animal.
