  • Patent number: 6050261
    Abstract: A backframe for a self contained breathing apparatus (SCBA) is formed of a molded shell having some depth, and a closure plate fixed to the shell to provide an enclosed volume. The molded shell with the closure plate yields a good weight-to-strength ratio, and provides a water- and dust-resistant enclosure for control components of the SCBA. A water-tight battery compartment is enclosed within the shell so the batteries are separated from other components. A low air pressure alarm provides an auditory signal, and may also include a tactile signal. A buddy breathing hose can be pulled from the backframe to provide a reasonable length tether; and, by connecting two such buddy breathing hoses, twice the length is provided.

  • Patent number: 6010431
    Abstract: A hand stretching method and apparatus mimics a well known exercise to reduce the problems with repetitive stress injury. A body of resiliently deformable material has flat and parallel top and bottom surfaces, with a cutout at one edge of the body. A user's hand is placed on the body, with the palm of the hand spanning the cutout. By pushing down on the hand, the opposite sides of the palm are urged apart, opening the carpal tunnel and relieving compression on the blood vessels and nerves. A user may place one hand on each surface of the body and urge the hands towards each other for treatment of both hands simultaneously. The body is preferably made of an expanded polymeric material such as polyurethane. Layers having different compression factors may be utilized; and, darker colored surface layers of material may be adhered to the top and bottom surfaces so the surfaces will not readily show dirt.

  • Patent number: 6000272
    Abstract: A vehicle repair rack having a platform for receiving vehicles for straightening is tilted as it is raised from the floor for easier loading of low vehicles, without the vehicle's bottoming out. The repair rack uses a parallel linkage to raise the platform. The platform is one link of the parallel linkage; and, the link that is parallel to the platform is allowed to elongate as the platform is raised, thereby causing the platform to move into non-parallelism with respect to the elongated link, so the platform is tilted. The parallel linkage includes legs as the other two links, and a connecting rod between the two legs is the elongating link. One end of the connecting rod has a slot that allows the connecting rod to move axially to a limited extent for the elongation.
