  • Patent number: 7081206
    Abstract: The filter removes volatile, particulate and water-based contaminants from a fluid, such as lubricating oil, of a different density than the contaminants. The device has a cone shaped, jet-propelled, helical-spiral wiper rotor creating centrifugal forces that separate the volatile and heavier particulate matter. Ports in a base assembly facilitate removal of the separated contaminants. A settling tank with vertical grid filter minimizes turbulence for further separation of heavier particulate matter. A volatile tank with vertical grid filter and flow restrictor minimizes turbulence to allow volatiles to rise from the fluid. A filter tank filters out remaining particulate matter from the fluid. A combination of flow restrictors and baffles minimize cross-contamination, thereby maximizing purity of oil returned to the engine. The collection tanks are easily cleaned and reused. The compact design minimizes oil volume necessary for purification.

  • Patent number: 5134826
    Abstract: A panel connector for interconnecting and supporting panels along their side edges to form space divisions. The panel connector comprises a structural connecting post having a supporting bottom end and a securing top end. The connecting post has opposed parallel side walls with a first pair of side walls having hook receiving apertures spaced in groups along the connecting post. A clamp bracket is secured in the top corner of at least one panel to be secured to the connecting post. A clamp is associated with the bracket and has a hooking element which engages with the apertures in the top end of the connecting post and with hook cavities in the clamp bracket to rigidly connect the panel to the connecting post. The side edge of the panel is also provided with a hooking clamp spaced from the top end to engage with further hook receiving apertures provided along the connecting post.
