    • Satellite tracking apparatus for use on board ship as part of a maritime communications satellite terminal is disclosed. A directional antenna which is adapted to be trained in the direction of the satellite so as to be in communication therewith is mounted so as to be positioned about three axes, namely train, elevation, and cross-level axes. The mount also has a fourth axis which is parallel to or collinear with one of the other axes. This fourth axis may be a level axis which is movable with the antenna. A stable platform is movable with and rotatable about the level axis. Sensors on this platform provide outputs to servo controllers which rotate the antenna about the elevation and cross-level axes to maintain the platform stable. An azimuth sensor such as a gyro compass and sensors responsive to angular motion with respect to the train axis may also be mounted on the platform and provide outputs to a servo controller which controls the bearing or azimuth position of the antenna. An open loop control is provided for the level axis which establishes an equivalent angle between the stable platform and the true elevation line of sight (an angle equal to but opposite from the true elevation angle to the satellite). A mislevel is thereby created and sensed by the sensor for the elevation axis which provides an output that activates the elevation axis servo controller to reduce the mislevel to zero and null, thereby achieving the desired elevation of the antenna. The antenna is stabilized and decoupled from the motions (roll, pitch and yaw) of the ship and changes in the ship's heading, in that the sensors are mounted on the stable platform which moves with the antenna. The need for coordinate conversion computers responsive to sensors strapped down to the deck or other ship structure and for alignment of the antenna axes with the pitch or roll axis of the ship is also eliminated. The rotation of the antenna about its boresight axis is eliminated; thus avoiding misalignment between the polarization of the antenna and the satellite signals.

    • The method of bonding a pocket blank to a garment portion of the present invention comprises the steps of providing a pocket blank at a first station. The pocket blank is conveyed to a second station. The bottom and side margin tabs of the pocket blank are folded over the pocket body. Heat and pressure are utilized to apply a strip of heat fusing adhesive to a top margin tab of the pocket blank. Heat and pressure are also applied to the folded over side and bottom margin tabs to crease the same. Next, the top margin tab bearing the adhesive is folded over and heat and pressure are applied to bond the same to the pocket body. Heat and pressure are applied to fuse strips of the heat fusing adhesive to the side and bottom margin tabs of the pocket blank. The prepared pocket blank is then conveyed along the path of travel to a third station where an overlaid garment portion is heat and pressure bonded to the prepared pocket blank.A preferred apparatus for carrying out the method of bonding a pocket blank to a garment portion of the present invention is also set forth.
