Abstract: A condensate removal system is provided for use in association or connection with equipment that produces a liquid or condensate during operation. The condensate removal system is configured to receive a liquid or condensate produced by equipment and is configured to induce the liquid or condensate to flow from the system as liquid or condensate droplets and/or liquid or condensate vapor. The system is configured to contain and to vibrate a liquid or condensate received from equipment in an ultrasonic frequency zone to induce the liquid or condensate to form into droplets and/or vapors. The system is configured and arranged to force the droplets and vapors from the system and can be further configured to expel the droplets and vapors to an area external to the system and/or into a duct, for instance, to exhaust the droplets and vapors or to recirculate the droplets and vapor to equipment to provide cooling to the equipment and/or components of the equipment.

Abstract: A fan grill for use with a fan associated with an inlet ring is configured to flush mount in an inlet ring and to serve as a safety guard to help prevent finger insertion into, and to help inhibit debris from entering a fan. The fan grill can impede and disturb gas flow to a fan less than by using a non-flush mounted grill or guard. The fan grill includes radial ribs, concentric circular ribs and radial support ribs to form a grate, and tabs. The tabs and the radial support ribs are configured to bias the fan grill against a wall of an inlet ring to securely connect the fan grill in the inlet ring. The fan grill can be readily installed and securely connected to inlet rings or housings of existing fans.

Abstract: An aircraft duplex hinge assembly (10 or 10') configured for use in aircraft, especially helicopters, having a compound curvature airframe (130) configuration wherein the edges of access panels (100) and the corresponding airframe apertures have a beveled configuration. The duplex hinge assembly (10 or 10') includes dual hinge mechanisms (20) and a latching mechanism (50) to deactivate the duplex hinge mechanism (10) with the access panel (100) in the closed position. The dual hinge mechanisms (20) include a primary mounting bracket (22) secured in combination with the airframe (130), a secondary mounting bracket (24) secured in combination with the access panel (100), and an interconnecting member (26) having a straight segment (30), an arcuate segment (32), and a protective flat segment (34).
