Abstract: An apparatus for removing floating and subsurface contaminants from a machine tool coolant bath is disclosed. The apparatus comprises a floating skimmer for collecting floating contaminants from the surface of the bath connected to an oil trap having an imperforate shell with a fluid tight column extending below the interface. A return conduit and a positive displacement pump are in series with the skimmer and oil trap. A submersible pump is disposed in the bath near the bottom for collection of water and water density contaminants and is connected to a remote filter assembly having a housing and a removable filter element. The filter assembly and the oil trap are both accessible without affecting the operation of the machine.

Abstract: A buffing pad attachment system including a buffing pad and a drive element for use with a power buffer. The drive element has a threaded insert permitting attachment to a power buffer drive spindle and further includes a resilient body with a radial flange for supporting an associated buffing pad. The drive element also has a center body portion with a flexible wall collar with at least one screw threaded surface. The buffing pad includes a radial flange with one surface covered with buffing material, the other surface engaging the drive element support surface and a center portion having a screw threaded cylindrical collar for engagement with the collar on the drive element. Both the pad and the drive element are made from elastomeric materials and may thus be nondestructively separated from each other by unscrewing or, in the alternate, by intentional or unintentional deformation of the collar walls sufficient to disconnect the engaged collars.
