Abstract: Embodiments of the present invention are directed to an apparatus, system and associated method of operation that allows medium weight Class II equipment to be shock tested using a Medium Weight Shock Machine (MWSM) in a manner that adequately simulates the required shock response exhibited when subjected to underwater explosion (UNDEX), Heavyweight testing utilizing a FSP. Advantageously, such an apparatus, system and associated method allows for testing of Class II medium weight (e.g., about 500-4500 lbs.) equipment (e.g., submarine and surface vessel equipment) utilizing an MWSM instead of Heavyweight testing utilizing a Floating Shock Platform (FSP). Testing of Class II medium weight equipment in this manner significantly reduces cost of testing such equipment and increases safety associated with testing such equipment.

Abstract: A vehicle turn-table (10) comprises a detector (60), which has a device for calculating the position of a vehicle to be driven accurately onto a table (30), and a turning table (30) which turns in response to the calculating device of the detector. A pair of movable belts (40, 41) are provided on the table to lead the front (A, A') and the rear wheels (B, B') of the vehicle to the table, and if, when the front wheels of the vehicle are on the detector, the vehicle is out of position, the calculating device calculates a center point of the vehicle, and then computes the turning direction and range of the table from the center point. The table (30) is then caused to rotate until the wheels of the vehicle and the belts are in alignment.

Abstract: A turntable, for a vehicle such as an automobile, which employs several detectors arranged to determine whether an automobile is located on the turntable in a desired position. Since the desired position depends on the size of the automobile, at least three detectors are used, one for small, one for medium, and one for large automobiles. The output of the detectors is displayed by visual indication. When an automobile is detected in a proper position, the driver may energize the turntable driving motor to rotate the turntable any desired amount, for example, 180 degrees. As the turntable approaches the angular position in which it is to stop, a cam-follower signals the approach to that position, deenergizing the motor and may apply a brake. The turntable, however, coasts to its final position where a plunger is biased into a socket to lock the turntable. Upon restarting the turntable, the plunger is removed from the socket.

Abstract: A monorail track switch and method is disclosed wherein the track switch senses the approach of a train and automatically aligns itself to accommodate passage of the train.

Novel structure and method is also provided for lowering the movable track section onto rollers to facilitate movement and thereafter lifting the track section into horizontal alignment with the train path. Electronic lockout circuits prevent a train from overrunning the switch when the switch is in a nonaligned position.
