  • Device used in the retrieval of climbing equipment
    Patent number: 5873613
    Abstract: A small flexible device (12) is used in conjunction with various sized elastic bands (18), one of which is attached to a climbing sling (19). The large diameter end (14) of the retrieval device (12) contains an insertion notch (13) to facilitate the entry of a climbing rope. The rope is inserted the length of a longitudinal through hole (16), by use of the retrieval devices' (12) longitudinal slot (15). The retrieval device (12) is constructed with a small diameter end (17) opposite a large diameter end (14). The small diameter end (17) first passes through the large loop (21) of two loops previously formed in a sling (19) using an elastic band (18). The large diameter end (14) of the retrieval device (12) being smaller than the large diameter loop (21) of the sling (19) passes through the loop (21) unimpeded. The small diameter end (17) of retrieval device (12) then enters the small diameter loop (20) in the sling (19), the diameter of this loop (20) having been previously formed with an elastic band (18).

  • NMR surface coil positioning device
    Patent number: 4684894
    Abstract: A positioning device for a surface coil used in NMR scanning is described. A non-metallic container allows a MRI surface oil to reside therein. An elongated rod extending through an opening on a side of the container is attached to the coil. A clear cover is placed over the container which is then placed under the patient. As the NMR scanning is performed for medical diagnosis, the coil is adjusted to the desired position by movement of the rod.
