Abstract: Filter and manifold compensation assemblies for thermal compensation of a filter cavity and a manifold which include at least one a lever element pivotally coupled to the filter or manifold at a first pivot point, an anchoring element pivotally coupled to the lever element at the second pivot point and secured to the housing of the filter or manifold, and a thermal expansion element having a lower coefficient of thermal expansion than the filter cavity or manifold and pivotally coupled to the lever element. The relative thermal expansion of the thermal expansion element in comparison with the thermal expansion of the filter or manifold causes the lever element to articulate and to displace the housing for thermal compensation. The degree of each displacement is proportional to the ratio between the distance between the second and first pivot points and the distance between the second and the third pivot points.

Abstract: A hybrid switch actuator having six positions that are stable in the absence of current and in which displacement occurs between an initial position and a target position under the action of a current. The actuator includes a stator and a rotationally moveable rotor package. The stator has six pole shoes. Each pair of opposed pole shoes is equipped with a common exciting coil. The rotor package has two pairs of rotor poles magnetized transversely in alternate directions and a permanent magnet ring and two end caps adapted to be engaged around said permanent magnet ring. Each end cap is associated with two rotor poles having maximum radius regions that correspond to the area of each of the stator pole shoes and reduced radius regions positioned adjacent the maximum radius regions such that each rotor pole can be precisely aligned with each stator pole shoe.
