Abstract: A magnetic compass in which the compass card and magnet are relatively movable with respect to each other such that only the magnet is gimballed to seek alignment with the earth''s magnetic field irrespective of the inclination of the compass card. The compass magnet is rotatably mounted within a gimbal assembly and is operative to become aligned with the axis of the earth''s magnetic field to seek the dip angle of the magnetic field while providing a rotational torque to cause rotation of the compass card to its balanced position indicative of compass heading. In alternative implementation, the compass magnet is maintained in substantially horizontal disposition to enhance the restoring torque.

Abstract: The present disclosure is directed to a method and apparatus for removing shells from crustacea in which the crustacea is compelled to travel a predetermined path while being subjected to an incising action to open the shells and while moving at an increasing rate of speed during the incising action at the conclusion of which the meats and shell fragments are separated by floatation.

Abstract: Apparatus for converting the energy of surface waves in a liquid such as an ocean, comprising a buoyant helical member mounted for rotation about an axis. The pitch of the helical member approximates the length of the expected waves and the member is floated on the surface with its axis oriented so that each wave traverses the helix lengthwise and buoyantly supports successive sections thereof causing it to rotate about its axis. The helix is coupled with rotary driven means such as an electrical generator.

Abstract: Apparatus for converting the energy of surface waves in a liquid such as an ocean, comprising an array of buoyant helical members each mounted for rotation about an axis. The pitch of the helical members equals or is greater than the length of the expected waves and the members are floated on the surface with their axes oriented so that wave length of the waves matches the pitch of the helices times the cosine of the angle between the helical axes and the direction of wave propagation. In one embodiment the array is a large chevron formed of two groups of helical members and is pivotable about the apex of the chevron. In another embodiment the helical members are arranged in zig-zag fashion. Means are provided for adjusting the angles between the arms of the chevron in the one case, and the adjacent arms of the zig-zag in the other case.

Abstract: A method and apparatus for providing a position location based on transmission of substantially parallel, collimated, coherent signal beams from a reference position, the beams being rotated in fixed parallel relation to one another about the reference position. The determination of the distance of the receiving position from the reference position, or the determination of the azimuth of the receiving position from a predetermined reference direction through the reference position, or both, is determined according to incremental angular rotation of the beams independently of the angular velocity of rotation.
