Abstract: A porous intermediate compact is first prepared from metal particles, carbon and a temporary binder. The compact is then heated to remove the binder and then infiltrated with the vapor of a metal having a melting point lower than the compact.

Abstract: The improved friction facing has a porous, resilient fused metallic matrix with a second metal having a lower boiling point being infused into and alloyed with the matrix.

Abstract: A sliding lock mechanism is mounted behind the front wall of the chassis, and associated openings are provided in the front and side walls of the chassis to respectively provide operator access to the lock mechanism and allow it to be reciprocally moved so as to extend through the side wall opening to engage a flange surface of the cabinet to thereby lock the chassis in its installed position. A fastener is also provided in the front wall opening to secure the locking member in its engaged position.

Abstract: The intermediate partition of a room air conditioner is provided with a downwardly extending slot in its upper edge such that installation and removal of the motor, with its attached fans, can be easily accomplished without removal of the partition. A filler plate is provided for insertion into the slot after the motor has been installed into its mount in the outdoor section.

Abstract: The discharge air sweep mechanism for an air conditioner is provided with slippage in its drive linkage such that the position of the vanes can be manually adjusted when the drive motor is turned off, or if the vanes become jammed during normal air sweep operation, the drive motor can continue to operate without damage to the mechanism. In one form of linkage, frictional engagement is provided by a pair of arms that are biased together with engaged member disposed therebetween, with the engaged member being allowed to slide between the arms upon the occurrences of either of the above mentioned conditions. Vane stop means is provided to automatically recalibrate the relative positions when normal air sweep operation is resumed.

Abstract: The fan drive motor mount of a room air conditioner is mounted on the base pan with the edge of one U-shaped member fastened directly to the base pan and with the side walls of the other U-shaped member partially overlapping the side walls of the first member and having means to secure the two members in an adjustable manner such that the first and second members can be appropriately spaced so as to accommodate any of various sized motors.

Abstract: Integrally formed with a molded plastic housing for a room air conditioner, is a pair of axially spaced walls whose inner edges closely surround the periphery of the condenser fan such that the dead air space created between the walls tends to prevent the recirculation of air around the fan periphery when the fan is in operation.

Abstract: A duct adapter for use in conjunction with an air conditioning unit is disclosed. This adapter attached to a discharge opening of a Packaged Terminal Air Conditioning unit and acts to divide the stream of conditioned air into multiple streams, one being discharged into the enclosure containing the air conditioning unit and a separate stream being discharged into an extension duct for delivery at a distant location. The extension duct is attached to a bracket fixed to the side of a through-the-wall sleeve, while the end of the extension in a slidable engagement so that the unit may slide out of the sleeve while the extension remains fixed to the sleeve.

Abstract: Apparatus for regulating air flow through a housing is disclosed. A baffle assembly including a ramp-like keeper is provided such that detents on the keeper contact the edge of the baffle to secure the baffle in position. When the baffle reaches a top position along the keeper it contacts a cam and returns to its initial position. The combination arrangement is utilized to either regulate the flow of air being discharged from the unit or to divert air between multiple outlets in the housing.

Abstract: A plastic sleeve assembly and an air conditioning unit are disclosed for mounting the air conditioning unit in a through-the-wall application. The sleeve assembly includes flange members with screw holes therethrough and standoffs about the screw holes, such that the air conditioning unit, having an L-shaped sealing flange thereon, when inserted into the sleeve and fastened thereto, causes the standoff on the flange to be in compression and not tension as the standoff makes contact with the L-shaped sealing flange when a fastener secures the air conditioner in the sleeve.

Abstract: A discharge air assembly for use in a room air conditioning unit is disclosed. The discharge air assembly includes both horizontal and vertical louvers for directing the air being discharged in any direction. The horizontal louvers are mounted in V-shaped slots defined by a vertical support member and are secured thereto by a louver retainer which via frictional fit maintains the louvers in the desired position. Additionally, control knobs mounted for sliding displacement are utilized to effect rotational displacement of the vertical air deflectors. The entire assembly is arranged as a subassembly which can be mounted with any room air unit having a discharge opening of a selected size.

Abstract: Apparatus and a method are disclosed for mounting a grille assembly to a sleeve designed for installation of an air conditioning unit. Rotatable mounting channels are secured to brackets of the grille assembly and may be manipulated from the interior of the sleeve to allow the grille assembly to be secured to the sleeve from the interior of the building. The sleeve includes a sleeve flange coacting with the grille flange and a channel support member having notches for receiving the rotatable mounting channels of the grille assembly for affixing the grille assembly to the sleeve.

Abstract: Apparatus and method for the assembly of an air conditioning unit including a tube sheet isolator. An electrically and thermally insulative isolator is provided for securing an aluminum heat exchanger to a steel component of the unit. The tube sheet isolators further serve to allow various subassemblies of the air conditioning unit to be slidably engaged to secure the components relative to one another.

Abstract: Apparatus for mounting a door for pivotal movement in an air conditioning unit. This door has as a portion thereof a pivot assembly having a series of contact surfaces which engage a series of surfaces of a top support so that the door may be rotated relative to the top support. The entire mechanism is formed of two components which, when assembled, provide a rotational mechanism hidden from view. An over center pressure applying means to secure the door in the fully open position is additionally disclosed.

Abstract: Apparatus for securing a front cover to an air conditioning unit is disclosed. This apparatus includes a front cover having pivoting means and including a fastening lip for securing the unit in the closed position and a flange for securing the unit in the service position. An air conditioning unit assembly is additionally provided having a pivot means for coacting with the cover and a control panel extension for securing the flange of the cover to maintain the cover in the service position. A support lip is also provided for coacting with the fastening lip of the cover to maintain same in the closed position.

Abstract: Apparatus for regulating air flow through a housing is disclosed. A damper assembly including a bowed leaf spring is provided such that the leaf spring contacts the edge of the damper to secure the damper in position. The combination arrangement is utilized to either regulate the flow of air being discharged from the unit or to divert air between multiple outlets in the housing.

Abstract: A duct adapter for use in conjunction with an air conditioning unit is disclosed. This adapter attaches to a discharge opening of an air conditioning unit and acts to divide the stream of conditioned air into multiple streams, one being discharged into the enclosure containing the air conditioning unit and a separate stream being discharged into a duct for delivery at a distant location. Means for attaching the adapter to the air conditioning unit and a damper assembly therein are additionally disclosed.
