    摘要： A fretted neck of a guitar having a plurality of strings spaced above the fretboard and a capo selectively movable along the length of the neck for retaining all of the strings in abutting relationship to the fretboard. The capo includes a clamp frame having a generally horizontally extending portion that mounts a retainer bar and a generally vertically extending portion, a finger operated clamp member, and a torsion spring mounting the clamp member on the clamp frame and resiliently urging it to a clamping position, and the torsion spring being mounted on the clamp frame. In one embodiment the retainer bar mounts a roller for each string while in a second embodiment the retainer bar mounts rollers with one of the rollers being of a length to extend across two strings. In a third embodiment the retainer bar mounts two plastic inserts that have downwardly extending rectangular teeth for holding the guitar strings against the fretboard.

    摘要： A self-contained, implantable device for controlling passage of material through internal body conduits, and in particular to control the material passage through a closure point commonly referred to as a sphincter, such as flow through the urethra from the bladder, movement through the bowel, or flow of medications from an artificial conduit that is implanted. The magnetic occluding device comprises a fixed magnetic pressure plate assembly, positioned on one side of a conduit, and a permanent magnet on an opposite side of the conduit. The permanent magnet can be moved so that the magnetic force between the pressure plate and the magnet can be altered from a position wherein the attraction between the movable magnet and the pressure plate carries the conduit between the magnet and the pressure plate to collapse to close off flow through the conduit, to a position wherein the conduit can open. The position of the magnetic poles of the movable magnet is changed either by being rotated or displacing it laterally with the pressure plate so the magnets tend to at least slightly repel each other when the conduit is to be opened. Control of the magnetic force is achieved to insure that the flow of blood in the conduit is not cut off.
