Abstract: A method of making a brush seal includes the steps of providing a plurality of brush filaments, and bonding a flexible plastic backing and a flexible plastic retainer to the filaments to secure the filaments together and form a flexible brush seal. A flexible brush seal adapted to provide a seal between a movable member and a structure includes a plurality of brush filaments; a flexible backing securing together the brush filaments; and a flexible plastic retainer bonded to the filaments, the retainer being adapted for mounting on an exterior surface of the structure.

Abstract: A method of pointing an antenna at a transmitter comprising the steps of: (a) varying the azimuth of the antenna dish a predetermined number of degrees in a first direction from a predetermined azimuth angle; (b) measuring a first signal strength of an incoming signal received by the antenna dish; (c) varying the azimuth of the antenna dish the same predetermined number of degrees in a second direction from the predetermined azimuth angle, where the second direction is opposite to the first direction; (d) measuring a second signal strength of the incoming signal received by the antenna dish; and (e) comparing the first signal strength to the second signal strength, and if the first signal strength substantially equals the second signal strength, the current predetermined azimuth angle represents the optimal angle of azimuth for the antenna dish.
