Abstract: A door system includes a header having a guide rail that has a central portion having a notch. A panel hanger is slidably coupled to the header. A door panel has a handle end portion releasably coupled to the panel hanger and a pivot end portion pivotably coupled to the panel hanger. The panel hanger and the door panel slide in unison between a closed position and a fully open position along a longitudinal plane. An interlock plate is positioned to extend upwardly from the door panel, and has a downwardly extending guide slot that slidably receives the guide rail of the header. When the door panel is in the fully open position, the interlock plate is aligned with the notch of the guide rail of the header in a direction orthogonal to the longitudinal plane to facilitate a pivoting of the door panel away from the longitudinal plane.

The method may further include pivoting the first door to the closed position, and pivoting a second door about a second pivot axis from a closed position to an open position when the first door is in the closed position such that the second door acts as an outlet facing in a direction opposite the first door. The method may additionally include pivoting the second pivot axis about the first pivot axis when pivoting the second door, the second door being of a smaller size than the first door and forming at least a portion of the first door.

Abstract: Disclosed is a modular assembly device for providing adequate and efficient ventilation, temperature control, and insulation in poultry houses. The disclosed invention relates to an automated or manually-operated modular shutter system for tunnel ventilation in poultry houses, the system being self-sealed by the poultry house's internal negative static pressure. All the shutters in a modular shutter unit are designed to open and close in unison by means of specially-designed hinges and hinge spacers. In the preferred embodiment, there are four shutters per modular shutter unit, all of the same construction and dimensions. The shutters are designed with beveled horizontal edges and end cap seals, which together provide an efficient and practically airtight fit against each other when closed. The shutters are also of sufficient thickness to accommodate internal insulation if necessary to raise the insulation values needed for the poultry houses in cold winter months.

Abstract: A structural element for the fabrication of a panel of a sectional door, which is movable between a closed and an open position along a predetermined pathway. The sectional door possesses a shell, generally of metal, having two mutually parallel sides, bent back on themselves, thus essentially creating structural elements aligned somewhat perpendicularly to the predetermined pathway. When in the closed position, the shell is characterized by forming an outer door surface which is external to the space to be closed, and forming an internal door surface opposed thereto.

Abstract: An active rinse shield designed to protect electrofill chemical baths from excessive dilution during rinse sprays on the semiconductor wafer. The shield uses overlapping blades to cover the bath, making a physical barrier between the bath chemistry and the wafer rinse water. The blades are interconnecting ribs that actuate around a common pivot axis. A linear mechanical actuator controls the blade movement, moving the top-most blade, which in turn, moves an adjacent lower blade. Each upper blade is interconnected to an adjacent lower blade by upper and lower ledges, a pivot boss and interlocking cut, and a curved ledge on each blade's body surface. The interconnecting features allow the blades to move one another out for extension or in for retraction. The interlocking blades are inclined above one another, forming grooves to redirect the rinse water away from the chemical bath.
