Abstract: A filter apparatus is provided. The filter apparatus includes a filter element. The filter element includes filter media supported in a frame construction. The frame construction having opposed side panels and a rectangular border flange along a first end. The rectangular border flange projects outward from and extending around the opposed side panels. The first end is an inlet end or an outlet end of the filter element. The filter apparatus includes a filter frame adapter formed separately from the frame construction and secured to the frame construction to adapt the filter element for a different mounting interface. The filter frame adapter includes a pair of complimentary adapter flanges each projecting outward relative to one of the opposed side panels. The adapter flanges are at a second end that is opposite a first end. The second end is at the inlet end or the outlet end.

Abstract: A door stay device for automatically locking a door in an open position includes a first component adapted to be attached to a stationary support, the first component including a plate having a curved cam edge with a radius matched to a swinging movement of the door between closed and open positions. The plate has a slot open at the cam edge at a location corresponding to the open position of the door. A second component is adapted to be secured at a lower or upper edge of a door, the second component having a locking member arranged to move into the slot when the locking member is aligned with the slot and the door is in the open position.

Abstract: Embodiments of the present invention include a filter clamping device for use in a filtering system that provides filtered intake air for a power generation facility. In some embodiments, a filter clamp is provided, which includes an over-center action mechanism that locks the clamp in place against the filter gasket. Some embodiments also include a camming surface that provides gradually increasing pressure on the filter gasket as the clamp is engaged. The clamp may also include a stop that engages the filter frame at a predetermined position and determines, in part, the amount of clamping pressure applied to the filter.

Abstract: A method for designing an air intake apparatus. The method includes receiving an indication of a requirement. A number of structural members to be used in the air intake and, optionally, one or more dimensions corresponding to the structural members are determined based at least in part on the requirement. A three-dimensional model of an air intake is generated based at least in part on the plurality of structural members and presented. One or more two-dimensional models may be generated based on the three-dimensional model and may further be output as manufacturing diagrams.
