摘要： An assembly controls the liquid level in a vessel in which a submersible pump is disposed. The assembly has a switch housing and a float housing, arranged proximate to each other. A switch in the switch housing selectively energizes a motor associated with the pump. When a float disposed in the float housing moves in response to a change in the liquid level of the vessel, the movement is coupled to the switch by a pair of magnets arranged in attractive relationship to each other. One of the magnets is in the switch housing and the other is in the float housing. The magnets interact by providing force fields that acts through a wall that separates the switch housing and the float housing. A lever on which the switch housing magnet is positioned tilts the magnets away from alignment as they approach each other, reducing the increase in attractive force therebetween.

摘要： An equalizer bank with interference reduction is disclosed. The equalizer bank with interference reduction comprises a front-shelving filter, a plurality of peak filters, a rear-shelving filter and a plurality of compensators. The center frequency and the quality factor of each compensator are designed intentionally to be identical to those of the corresponding peak filter. When a user selects a specific gain level, the corresponding parameters that determine the peak filter and the compensator are retrieved directly and a complex calculation is skipped. Therefore, an audio signal can be equalized more efficiently with lower hardware cost.

摘要： An electric motor includes a stator, a housing supporting the stator and having a bearing seat with an inner surface and an inner end, a bearing having an outer surface, a shaft rotatably supported by the bearing, and a rotor supported by the shaft. The motor also includes a tolerance ring having an interior surface, an exterior surface disposed against the bearing seat inner surface, and a plurality of elastic corrugations. Each of the elastic corrugations projects radially from the interior surface, defining a shoulder section disposed between the bearing and the inner end of the bearing seat. The shoulder section generates a spring force against the bearing to axially and radially support the bearing and to axially preload the bearing.

The seal locates between the bearing shaft and the cone for sealing lubricant therein. The seal includes at least one rigid seal ring having a cemented carbide body and an annular PCD face located on it. The mating face may also be of a PCD material. The cemented carbide body contains a binder that migrates into the PCD face while the PCD face is being formed. A binder-free region is leached on the surface of the PCD face.
