  • Patent number: 4584438
    Abstract: An electromechanical transducer converts an electrical signal into distortion free sound. Two equal coils are mounted on a sleeve within separate magnetic circuits. The coils are wound in identical mirror image symmetry and the magnetic circuits are disposed symmetrically of the sleeve. The application of an electric signal at the terminals of the coils causes the sleeve and diaphragm to reciprocate linearly under balanced forces within the air gap defined by the magnetic circuits.
    Type: Grant

  • Patent number: 4036510
    Abstract: A safety ski binding wherein the boot is releasably mounted on a sole plate which in turn is releasably secured to the ski so as to be released therefrom upon the application of forces of predetermined magnitude and direction. The sole plate may be mounted on the ski by two pairs of mounting elements, one of said mounting elements in each pair being carried by said sole plate, the other mounting element in each said pair being adapted for mounting on said ski. Said pairs of mounting elements may be positioned in fixed spaced relation on opposite sides of the longitudinal center of said sole plate. One or both of said pairs of mounting elements may include a plunger of low profile not projecting above the upper surface of the sole plate. One or both of said low profile plungers may be positioned below said upper surface of said sole plate.
    Type: Grant

The sole plate may be mounted on the ski by two pairs of mounting elements, one of said mounting elements in each pair being carried by said sole plate, the other mounting element in each said pair being adapted for mounting on said ski. Said pairs of mounting means may be positioned in fixed spaced relation on opposite sides of the longitudinal center of said sole plate. One or both of said pairs of mounting elements may include a plunger of low profile not projecting above the upper surface of the sole plate. One or both of said low profile plungers may be positioned below said upper surface of said sole plate.
