Abstract: In a nuclear process control system, a priority logic module (PLM) is provided. The priority logic module comprises a plurality of input ports, each input port associated with one of a plurality of priorities, a plurality of output ports, and a test mode select port associated with a test mode select signal. The test mode select signal selects one of a normal mode or test mode, each mode being associated with matching signals received by the input ports to signals sent by the output ports. The priority logic module further comprises a configurable priority logic circuit, wherein the priority logic circuit maps one of the input ports to one of the output ports.

Abstract: A lightweight, portable hoisting apparatus which is easily securable into a standard receiver hitch of a truck or other vehicle which can be used for hoisting heavy objects such as motor vehicle engines and the like, a vertically extendable main support member preferably formed of box tubing is included which is obliquely oriented with respect to the ground at 70-90 degrees. A mounting head is slidably engageable with respect to the lower portion of the main support member and includes a mounting housing defining a vertical channel therein for receiving the main support member and a mounting arm extending outwardly to engage the vehicle hitch. A boom arm is pivotally mounted to the upper end of the main support member and includes a load attachment means preferably at the outermost end thereof.
