Abstract: An apparatus is provided for dissipating heat from a semiconductor device that meets dimensional requirements for the semiconductor device and provides enhanced cooling for the semiconductor device. The apparatus provides a relatively large surface area for transferring heat away from a semiconductor device, and provides for enhanced coolant flow through or around the apparatus. The apparatus includes a channel that may accommodate a heat pipe to further enhance transfer of heat away from the semiconductor device.

Abstract: A fluid pump having a pump housing, and an impeller in the housing and coupled to the drive shaft of a drive motor. An improved main seal is provided in the housing to seal the hole through which the drive shaft extends. The seal includes a carbon seal member having a flat end face in sliding relationship to the flat end face of a ceramic seal rotatable with the drive shaft and the impeller. The seal further includes a pre-loaded element which forces the two seal faces together. An improved mounting bracket is provided to mount the drive motor and the pump housing on a fixed support. The mounting bracket includes a central mounting plate and a pair of inclined, side wings which extend from the pump housing toward the drive motor so as to eliminate the need for a second bracket on the opposite side of the motor.

Abstract: A skim net assembly having an open frame with a number of sides, and a web coupled to the frame at one of the sides. The net is secured in some suitable manner to the frame in alignment with the central opening through the frame so as to trap and collect debris as the skim net assembly moves in the water of debris-containing water in a forward or lateral direction. The cross section of three sides of the frame is blade-like in configuration; thus, the three sides permit a shovel-like action when cleaning a swimming pool which allows debris to be more effectively forced into the net when the assembly is being pushed over the bottom or moved laterally over the bottom surface of a swimming pool. A pole is coupled to the frame in a manner such that the pole is adjustably mounted on the frame for angular movement into any one of a number of operative positions.
