  • Patent number: 8002869
    Abstract: An air cleaner includes a housing and an access cover. The internal volume of the housing can be reached through an opening in a side wall of the housing. A filter element having fluted filter media is removable and replaceable from the air cleaner. The housing is constructed and arranged to cam the element into sealing engagement with the housing. The access cover includes structure to help support and ensure proper seating of the filter element within the housing. A method of installing the filter element in the air cleaner includes sliding a portion of the filter element against a slide surface in the housing. A method of servicing an air cleaner includes tilting the filter element against a tilt surface in the housing to release a seal between the filter element and the housing. The filter element can have a handle to assist in servicing of the air cleaner.

  • Patent number: 6652784
    Abstract: Methods for selectively moving a microelectronic-device substrate assembly in a processing machine having a first side, a second side opposite the first side, and a processing path extending from the first side to the second side. The processing machine can also include a cassette proximate to a second side of the processing station that moves to position a substrate at the processing path. In one aspect of the invention, the substrate handling apparatus includes a guide member attached to the processing machine, an arm slidably attached to the guide member, and a clamp attached to the arm. The guide member is generally fixedly attached to the processing machine, and the guide member generally has a shape corresponding to the processing path. The arm can include a first section moveably attached to the guide member to translate along the guide member, and a second section projecting from the first section to position at least a portion of the second section at least proximate to the processing path.
