Abstract: A control for stopping the rotation of the output shafts of a plurality of multiplexed motors configured in columns and rows with the first connector of each motor in a given column connected in parallel and with the second connector of each motor of a given row of motors connected in parallel. Each motors includes a switch positioned to be actuated when the output shaft of the motor is in its home orientation. One contact of the switch is connected to a first contact of the motor and therefor receives power when the switch for the column is energized. The second connector of each switch in a given row are connected in parallel to a detector for detecting a change in electric potential. The detector will detect a change in potential when the rotating shaft of an energized motor rotates its output shaft to its home position thereby closing its associated switch.

Abstract: An electric switch having a circuit breaker includes a manually operable actuator that moves one contact between a first and a second position. A bimetal member moves another contact between a first and a second position in response to an electric current above a given threshold passing therethrough, and the movement of this contact to the second position releases a catch that retains a spring loaded indicator in its retracted position. The two contacts abut one another closing the circuit when both contacts are in their first positions. An excessive current will therefore break the circuit and release the indicator to move to the extended position. The releasable catch resets after the bimetal member has cooled and it will again retain the indicator in the retracted position when it is subsequently manually depressed.

Abstract: A falling object, such as a product falling from a magazine to a discharge chute of a vending machine, is detected using a rectangular light curtain having parallel sides. A plurality of light emitters are positioned along one side and a plurality of receptors are positioned along another side opposite the emitters. A timing circuit momentarily illuminates the emitters one at a time at a time while an electronic controller examines the outputs signal from all the receptors. Where one of the receptors fails to receive a signal from one of the emitters an object is presumed to have interrupted the signal. To work properly the electronic controller must complete a cycle of illuminating all the emitters within the time frame that a falling object interrupts the light curtain.

Abstract: An air-seal structure for pneumatic nailers includes a valve member movably engaged with the end cap of the nailer and a plurality of paths defined radially through a skirt portion of the valve member. The paths are in communication with air release passage defined in the end cap. A seal is mounted to the skirt portion of the valve member and closes the paths. The seal contacts an end of the cylinder when the trigger is not squeezed. The seal is sucked due to the difference of pressure so that it will not be loosened during movement of the valve member. A cushion member is connected to a disk member on the inside of the end cap so as to absorb shocks when the piston returns back to the ready position.

Abstract: A locking device is adapted for releasably locking a seat post relative to a seat tube of a bicycle frame, and includes a tubular body with a lower surrounding member to be secured to the seat tube. An upper surrounding member extends upwardly to terminate at an upper surrounding edge, and has an accommodating space for the seat post, and a slit extending downwardly from the upper surrounding edge. A plurality of protuberances are disposed on and project radially and inwardly of an inner surrounding wall surface of the upper surrounding member, and are angularly displaced from each other. Right and left jaw members are respectively attached on the upper surrounding member, and are moved by a tightening member toward each other to narrow the slit so as to bring the protuberances to abut against the seat post.

Abstract: The invention is a wheeled folding tray cart and method. The wheeled folding tray cart comprises a collapsible wheeled framework pivotally supporting a set of split shelves, each split shelf comprises a pair of half shelves. The wheeled folding tray cart moves between an open operating position wherein the set of split shelves are held in spaced-apart, stacked, horizontal orientation within the collapsible wheeled framework and a closed storage position wherein the collapsible wheeled framework is collapsed in manner to move each half shelf pair into an accordion-like, inverted “V”-shaped or accordion like configuration. An extension coiled spring attached to the collapsible wheeled framework assists in the movement of the wheeled folding tray cart between open operating position and the closed storage position. A sheath encloses at least a portion of the spring to provide resistance to the spring's movement to limit potential operator exposure to pinch injuries.
