Abstract: A locking mechanism for a casement window assembly includes a housing adapted to be mounted on the window assembly, an actuator operably connected to the housing and pivotable about a fulcrum, and a linkage member having a first channel and a second channel. The housing has an elongated opening having opposed ends. The actuator includes an actuator body having a first pin and a second pin located thereon. The linkage member is connected to the actuator such that the first pin is received in the first channel and the second pin is received in the second channel. Pivoting the actuator about the fulcrum causes the first pin to move within the first channel and the second pin to move within the second channel, moving the linkage member along the opening, from one end of the opening to the other end of the opening.

Abstract: A galley waste disposal system is provided for use with an existing vacuum collection system. The galley waste disposal system includes a basin for receiving galley waste and a discharge valve connected between the basin and a collection tank. The discharge valve is vacuum-operated and has an actuating port. An electrically-operated vacuum control valve is connected between the actuating port and a vacuum source. A flush element is also provided that is actuatable to produce a discharge command. A controller is operably connected to the control valve and is selectively operable in response to the discharge command to place the actuating port in fluid communication with the vacuum source, thereby to open the discharge valve. In addition, the discharge valve, vacuum control valve, and controller may be housed in an enclosure suitable for mounting remotely from the basin.
