Abstract: A portable, double bevel, combination table saw and slide miter saw comprising a horizontally disposed working platform with an elongated slot, is supported by a frame. A saw assembly is pivotably mounted beneath the working platform, with a saw blade that protrudes through the slot to cut a workpiece on the platform whereby stationary workpiece operations as well as moving workpiece operations may be executed. The stationary workpiece operations are executed from one side of the platform, and moving workpiece operations are executed from the opposite side of the platform, with separate appropriate controls on each side. The possibility of interference between saw assembly parts and the underside of the work platform inherent in double bevel configurations is avoided by the self-adjustment of the maximum depth for the workpiece bevel cuts.

Abstract: A flush control mechanism for a toilet and associated method that enables the toilet to be flushed with either a long flush cycle for solid wastes or a short flush cycle for liquid wastes. The present invention includes a nonbouyant flush valve that controls the duration of the flush cycle. A handle assembly is provided that is rotatably manipulative around its longitudinal axis from a set orientation to a rotated orientation. The handle assembly is also reciprocally manipulative along its longitudinal axis from an extended position to a retracted position. A first mechanism is coupled to the handle assembly and the flush valve for temporarily maintaining the flush valve in an open condition when the handle assembly is rotated into its rotated orientation. The flush valve remains open until the tank drains to a first level.

Abstract: An improved control system for a plurality of magnetic disc storage devices which connects one of said devices to a central processing unit for the transmission of data records to or from the central processing unit. The improvement comprises a unit logic controller connected to each disc storage device for receiving and storing priority control information and sector address information associated with a seek operation for a data record address. The unit logic controllers raise an alert signal when the data record address being sought is near the read-write head. The disc storage device having the highest priority associated with its alert signal is connected to the central processing unit for the transfer of data records by the control system. The improved control system requires that the central processing unit be connected to the disc storage device and the unit logic controller for the minimum amount of time during the process of locating a desired data record.
