A conveyor with a plurality of article supporting stations has a reciprocatable shuttle mechanism equipped with dogs which engage and advance articles one station on each advance stroke of the shuttle. All dogs are set in article engaging position at the end of each return stroke of the shuttle. A series of accumulating stations extends from the unloading toward the loading end of the conveyor, and accumulating mechanism actuatable independently of the shuttle is operable to reset the dogs of each of these stations to non-engaging position in response to the presence of articles. A control system normally operates the conveyor on a simple cycle of successive advance and return strokes of the shuttle until, with articles detected at the last two stations, the accumulating mechanism is cycled prior to a shuttle advance stroke.

A self-powered and self-contained portable testing apparatus for monitoring critical operating parameters of an aircraft reciprocating engine. The portable testing apparatus is typically used for the running-in of aircraft engines after overhaul, before returning the engines to service. The portable testing apparatus includes a plurality of sensors for sensing and generating analog signals corresponding to temperature at various locations inside and outside the engine. A multiposition selector switch electrically connects to each of the sensors. The switch is designed to select one of the analog temperature signals and to transmit the selected signal to a computer having a display. The computer converts the selected signal into a digital temperature signal and indicates the digital signal in corresponding numerical representation on its display. Also included is a tachometer for measuring and displaying the operating speed of the engine. The tachometer has a memory, and can calculate and store in its memory the average operating speed of the engine and the maximum operating speed achieved during the run-in of the engine.

In a power driven roller conveyor having a plurality of rollers each connected to a shaft and a plurality of driven sprockets one of which is rotatably mounted on each of the shafts, a torque-responsive coupling is interposed between a driving member connected to each sprocket and a driven member connected to each shaft so that the rotation of any roller will be interrupted if the resistance to rotation exceeds a desired value, thereby permitting articles on the conveyor to be stopped and accumulated without undue scuffing and wear on the articles or on the rollers. The coupling consists of a wobble plate which is connected to the driven member for oscillating movement about a center coincident with the axis of the shaft and which has a surface disposed transversely to the axis of the shaft and facing the driving member. The wobble plate is spring urged toward the driving member. A driving ball, rotatably mounted in a socket in the driving member engages and displaces the surface of the wobble plate to an oblique relation with the axis of the shaft, thus forming, a coupling which will transmit motion until the resistance thereto is sufficient to overcome the spring bias on the wobble plate.
