Abstract: A filtering apparatus with interconnected, rotatable drive wheel apparatus and driven wheel apparatus for rotating a pump impeller (32), preferably dual drive and driven pulley wheels (36 and 40) and an interconnecting belt (41) is described. A motor (13) is mounted on the underside (12a) of a housing (12) adjacent an outside sidewall 100a of a tank (100) which rotates the drive pulley wheel (40), the belt (41) and the driven pulley wheel (36). The driven pulley wheel (36) is mounted on a shaft (33) supporting a submerged impeller (32) inside a pump body (15). The filtering apparatus with the drive and driven wheel (36 and 40) provides positive fluid flow without priming and good balance for the filtering apparatus when mounted on the tank (100).

Abstract: A tooling aid for a machine tool includes an indicating platform adapted for use with a dial indicator for indicating whether the head of the machine tool is square to the work table. The indicating platform includes a top member which defines a flat, smooth surface. Support members connected to the top member space the top member parallel to the surface of the work table. The arm of the dial indicator rides on the top member as the head of the machine tool is rotated about the work table to provide a measure of the degree of squareness of the head with respect to the work table.

Abstract: A device for mounting an antenna or the like has a base plate, a top plate detachably connectable to the base plate and a swiveling or rotatable antenna-receiving member. The member is securely retained between the base plate and top plate. The present device is particularly efficacious in mounting a citizen's band radio antenna to the trunk lid of an automobile.
