Pumps, for example, bilge pumps, comprise a pump housing including an inlet and an outlet, a motor and an impeller assembly coupled to the motor for pumping liquid which passes through the outlet. The motor is advantageously cooled by pumped liquid while being protected from the pumped liquid. Further, the motor is turned on and off in response to actual operating conditions, thereby increasing pump life and reducing overall power consumption. The pump provides contoured facing surfaces which provide a dynamically efficient flow path for the pumped liquid. In addition, a switch housing is preferably provided to allow liquid to contact an activator assembly which turns the motor on.

A vehicular external rearview mirror system comprises a twin-arm assembly comprising a pair of parallel support arms connected at one end to a base attached to the vehicle and movably connected at another end to a reflective element assembly through a movable support bracket. The support bracket supports a reflective element assembly and is attached to the twin-arm assembly through a pair of integral bearings which translate along the arms to extend or retract the reflective element assembly. In one embodiment, the bearing imparts a friction force to the arm to enable the bracket to be moved along the arm under the influence of an extension/retraction force, but to maintain the bracket at a selected position along the arm when the force is removed. In another embodiment, the bearing is adapted for frictionless translation of the bracket along the arms under the influence of a powerextend actuator. In yet another embodiment, the bearing is integrated into the movable support bracket for frictional support of the bracket on the arms.

A fractal fluid distribution system for use in a vessel is described wherein two phases are distributed separately and then finally mixed in a set of stacked fractal plates which are off set from one another by rotation around a central axis. Each of the two phases is fed from the top of the vessel. The flow paths of each individual phase have approximately the same length. A header is provided to allow feeding the two phases separately without interference with the final distribution outlets.

A rearview mirror tilt actuator comprises a clutch assembly that selectively transfers torque from an actuator motor to one of at least two output shafts based upon the speed of the motor. One output shaft can pivot the mirror about a first axis of rotation; another output shaft can pivot the mirror about a second axis of rotation. One output shaft can pivot the mirror housing; the other output shaft can extend and retract the mirror housing. At a low speed, the clutch assembly is disengaged, thus only the first output shaft is activated. At a high speed, the clutch assembly is engaged, thus both output shafts are activated. The mirror assembly described herein also has an improved mass configuration which allows for lower moments of inertia in the direction of mirror travel.

A tip (10) for the dispensing of a material such as from a syringe (31) has an inlet end (11) and an outlet end (12) and a body (13). The tip (10) is also provided with a cap (50) that physically engages and cooperates with at least one nub (51) to improve the removable securing of the cap (50) to the tip (10). The cap (50) covers the outlet end (12) and has an interior surface (52) dimensioned to physically contact the nubs (51) when in place upon the tip (10).

The invention provides an ultrasonic dental scaler insert having a soft grip, and a method of making it. In the method a soft grip member is provided having an elastomeric wall affixed to a rigid wall. This soft grip member is then connected to an ultrasonic dental scaler insert to form an ultrasonic dental scaler insert having a soft grip.

An exterior rearview mirror assembly for use on an automotive vehicle comprises a base member having a mounting plate for fixedly securing the mirror assembly to the side of the vehicle and a base plate extending outwardly therefrom. An elongated support arm has a first end pivotally coupled to the base plate and an opposite second end supporting a concave mirror housing. The mirror housing includes a peripheral rim defining an opening for receiving a reflective glass mirror pane. The mirror pane includes a directional indicator for providing directional signaling of the intended vehicle path. The mirror assembly further includes a puddle lamp for illuminating areas adjacent to the vehicle for entry and exit and for signaling rearward of the vehicle. Finally, the mirror assembly includes a display panel operatively connected to the vehicle for displaying information indicative of the vehicles operating conditions.
