  • Patent number: 6545855
    Abstract: An apparatus (100) for reducing inductance in a capacitor having a first terminal (12) and a spaced-apart second terminal (14), includes a first conductive plate (120) and a second conductive plate (140). The first conductive plate (120) is electrically coupled to the first terminal (12). The second conductive plate (140) is electrically coupled to the second terminal (14) and is disposed in parallel with the first conductive plate (120) so as to overlap at least a portion of the first conductive plate (120). An insulating member (122 and 142) is disposed between the first conductive plate (120) and the second conductive plate (140). The insulating member (122 and 142) insulates the first conductive plate (120) from the second conductive plate (140).

  • Patent number: 4629841
    Abstract: A hermetically sealed float switch having a bistable ball cage therein. The ball cage is free to pivot between either of two spring biased, over center positions responsive to the position of a ball which is free to roll from either end of the race through the cage to the other end of the race. An over center spring holds the ball cage in its last operated position. A safety arm prevents the ball cage from changing its attitude in any manner which, if uncontrolled, might permit the ball to escape into an inoperative position which might capture it behind the ball cage. Adjustment is provided for the on and off levels of the switch responsive to tether length.
