Abstract: An air handling apparatus for a HVAC system of a building. The air handling apparatus includes an enclosure having at least one inlet opening for drawing outside air into the enclosure, and at least one outlet opening for directing air from within the enclosure to outside the enclosure. At least one fan is mounted within the enclosure for drawing air through the enclosure. A burner box is centrally located within the enclosure for heating outside air drawn into the enclosure through the at least one inlet opening.

Abstract: A low profile, high power electrical connector assembly is disclosed. The connector assembly includes a plug and a receptacle connector designed to be mounted on separate printed circuit boards. The plug and receptacle connectors are designed to be mated and thus allow the separate circuit boards to be electrically connected in tandem in either the same plane or perpendicular to one another. The connector assembly includes a plug contact and a receptacle contact provided with cooling slots and an at least partially open rear face configured to permit the dissipation of heat.

Abstract: A plate that is attached to a shaft to remove a door closer from the door completely. A door holder is used to set the plate in an "open" position, out of the way of the door. Once the plate is in the open position, the door is free to open and close without any force on it at all. If there is an emergency, the door holder releases the plate. The door closer then moves the plate against the door and closes the door. Once the door is closed, the plate can be reset by opening the door until the door holder is again engaged. In this way, people can operate the door without exertion while they are protected from emergencies.
