  • Patent number: 5832096
    Abstract: A loudspeaker including a voice coil and a counter coil connected in series to receive speaker signals. The counter coil is wrapped on the pole pieces in an opposite direction to the voice coil such that a first magnetic field generated by the voice coil is reduced by a second magnetic field generated by the counter coil. In addition, a stiffened and/or elongated voice coil support is provided to reduce distortion caused by a bowing effect of the voice coil due to a warped stationary magnetic field located in the air gap. An acoustically-transparent basket is also provided which minimizes reflected sound waves to further reduce distortion.

  • Patent number: 5826852
    Abstract: A bird feeder support which is mounted to a surface including a base member. The base member possesses an open channel which is accessible from the outer surface of the base member. An arm having a first end portion, a second portion, and an intermediate portion connecting the first and second end portions, extends from the base member. The arm also possesses at least one flange which is capable of fitting within the channel. The arm is mounted to the base member to permit the flange to extend in one direction and to reverse its orientation within the channel to an opposite second direction. A bird feeder is easily fastened to the arm and is, thus, positioned in two orientations when the flange of the arm is rotated within the channel.

  • Patent number: 5820227
    Abstract: An improved brake equalizer apparatus for equalizing fluid pressure and damping shock waves or pressure surges in fluid lines of a fluid pressure-actuated system, such as a hydraulic brake system. The apparatus has a shorter reaction time than a conventional brake equalizer, and can be manufactured with smaller overall length and weight. An important feature of the apparatus which results in reduced brake equalizer reaction time is an improved brake equalizer piston. The piston of the invention is shorter than a conventional brake equalizer piston (the ratio of the inventive piston's length to the length of the shock absorber which it abuts is substantially less than 0.5, and is preferably equal to about 0.23). The piston of the invention is also lighter than a conventional brake equalizer piston, and is preferably made of a hard, non-compressible, self-lubricating material.
