Abstract: Security apparatus for preventing deception of a coin acceptor unit by use of a moving magnetic field which a thief may produce by moving a hand magnet near the coin acceptor unit to induce currents in the mechanism's circuitry to cause a false determination that a proper coin has been received and allow unpaid operation of the controlled machinery; said apparatus having circuitry elements to detect a moving magnetic field and upon detection of said field to turn off power needed for operation of the coin acceptor unit and the machinery, and to keep said power off for a predetermined time out period, and to restore the coin acceptor unit to normal settings, allowing normal operation of the coin acceptor unit and machinery after expiration of said time out period, until such time as a moving magnetic field is again detected.

Abstract: Apparatus for lifting and transporting drywall panels on a lift platform has a pair of panel-supporting legs of square metal tubing attachable to side rails of a lift platform. Each of the legs is connected to the rails by an upper clamp at the top of the leg and a lower clamp at a middle location. A panel-receiving U-shaped channel is located on the opposite side of the leg, away from the rails. The lower clamp has a standoff member included in its connection to the leg, which serves to project the bottom of the legs outward at an angle. Rollers at the top and bottom of the legs provide low-friction rolling contact for weight bearing surfaces, and other rollers are placed to keep panels away from contacting the legs or other surfaces.

Abstract: A work transfer apparatus is equipped with a work feeder 23, a rotatable turn table 11 formed several work-storing pockets 11a at its outer periphery and a separation mechanism 24 provided between the work feeder 23 and the turn table 11. The separation mechanism 24 has a communicating passage 24a. A work detector (15a, 15b) is provided in the work-storing pocket 11a. A work stopper 14 is provided at the work feeder 23 on an upstream side of the work detector (15a, 15b), for separating a preceding work W1 and the succeeding work W2.

Abstract: For a point-of-sales rug selection from a stack thereof, a method of working a raised stack from the bottom up so that a rug assuming successively the bottom position is permitted to descend, each in turn, to a floor display position and, after the first descent using lowering cables, the cables having a length portion in a taut vertical condition to serve as tracking guides for the vertical descent by gravity of successive rugs.

Abstract: Apparatus for accumulating successive stacks of superimposed sheets on discrete pallets employs a conveyor which delivers a continuous imbricated stream of sheets to a stacking station where a pallet descends with an elevator and gathers a first stack. A separating finger is inserted into the accumulation of sheets at the stacking station at a level above the topmost sheet of the fully grown first stack.
