Abstract: A rapid response self-closing pressure equalization vent employs a frame supported in a compartment divider and a movable vent portion having a periphery sealingly engaging the frame in a closed position. Multiple resilient extension elements are attached to the frame and engage the movable vent portion for even displacement around a periphery of the movable vent portion relative to the frame to an open position responsive to a pressure differential on the movable vent portion. The resilient extension elements retract upon equalization of the pressure differential to reseat the movable vent portion in the frame.

Abstract: A computer implemented method for automatically stacking beams from a continuously moving live deck, wherein the method involves sequentially receiving a plurality of beams onto a stacking fork assembly, pivoting the stacking fork assembly from a receiving position to a stacking position forming a tier of beams, placing the tier on a pair of bidirectional moving members, moving the tier away from the stacking fork assembly, rotating the stacking fork assembly back to the receiving position to sequentially receive another plurality of beams, pivoting the plurality of beams forming a second tier, moving the first tier back to contact the second tier, moving the contacted first and second tier away from the stacking fork assembly enabling a third or fourth tier to be formed and contact the first and second tiers, forming a bundle.

Abstract: A collet mechanism that holds a cannula during molding of a syringe includes first and second arms that form an internal cavity. Each arm has a proximal end and a distal end. The first and second arms are in a closed position when the distal ends are moved toward the internal cavity and are in an open position when the distal ends are positioned away from the internal cavity. First and second cannula guides respectively are mounted proximate the distal ends of the first and second arms and extend into the internal cavity. The first and second cannula guides clamp a portion of the cannula to hold the cannula when the first and second arms are in the closed position.

Abstract: Methods are provided of forming a plurality of fan-shaped effusion holes on a combustor having a surface, each hole having an outlet on the combustor surface. The method may include rotating the combustor relative to a laser beam, and positioning the combustor to a first position where the laser beam is at a first predetermined angle relative to the combustor surface. The laser beam is pulsed at the combustor surface to form a first plurality of trepan cuts. The first predetermined angle is adjusted to a second position where the laser beam is at a second predetermined angle relative to the combustor surface. The laser beam is pulsed at each trepan cut of the first plurality of trepan cuts, to thereby form a cut for at least a portion of the fan shape of each effusion hole outlet, wherein each cut overlaps a trepan cut of the first plurality of trepan cuts.

Abstract: The specification describes techniques for isolating noisy subcircuits in integrated analog/digital devices. Isolation is obtained using a modification of triple well isolation wherein the deep isolation implant is restricted to the digital circuits only to prevent noise from the digital circuits from propagating to the analog sections through the buried implant. Resistor sections are also separated from the buried isolation implant.

Abstract: A method of shrinking an existing mixed signal IC containing analog and digital circuitry includes the step of first enlarging (growing) the analog circuitry by a first ratio, followed by the step of recombining the enlarged analog circuitry with the existing digital circuitry and, then, optically shrinking the recombined analog and digital circuits by a second ratio. In one embodiment the analog circuits are enlarged by a factor that will offset the subsequent optical shrink. As a result, the analog circuitry is essentially unchanged on silicon, while the digital circuitry will be smaller, thereby making the overall chip smaller.
