Abstract: A telescopic manipulation arm includes a module formed by two segments and a toggle joint. All movements of the toggle joint are transmitted across the module by identical mechanisms in such a way that the friction and inertia are the same for each movement. These mechanisms incorporate shafts positioned equidistantly of an axis in the lower segment and shafts positioned equidistantly of the axis in an upper segment. Shafts are provided for carrying identical pinions, which engage on identical toothed gears, and which are also engaged on substantially identical pinions rotatable with the shafts.

Abstract: A system for controlling x, y and z directional movement of a point adjacent to the free end of an arm composed of a plurality of interconnected articulated arm segments mounted for movement relative to at least three axes and providing for individual, independent control of movement of the point in any selected one of the x, y or z directions by controllably relatively adjusting the relationships between the segments. The system is particularly suitable for use in equipment when the arm incorporates a boom and stick such as backhoes or the like.

Abstract: Transferring device for a semiconductor wafer or like part includes a rotatable carrying arm rotatably for carrying a semiconductor wafer or part from its initial position and through a first angle. The rotatable carrying arm has a holding portion for a wafer or part, and a cam follower portion. A motor rotates the rotatable carrying arm through an angle slightly greater than the first angle slightly past a desired position for the wafer. Then, an eccentric cam returns the carrying arm through a second, incremental angle, for bringing the carrying arm, and, hence, the wafer held thereby, to the desired position.

Abstract: A rapid coin acceptor is disclosed which is capable of discriminating valid coins or tokens from counterfeit coins or tokens and for accepting the valid coins or tokens as they fall by gravity through the device. The coin acceptor includes a coin introduction chute which receives coins or tokens and directs the coins by gravity feed to a coin sensing gate which is positioned in vertical registry below the bottom of the coin introduction chute. The coin sensing gate is equipped with a plurality of sensors to sense various parameters of the coin or token for authentication purposes as the coin or token drops through the coin sensing gate. The coin sensing gate is designed of height between one and one and one-half times the diameter of the coin to assure substantially instantaneous response to prevent the rapid insertion of a spurious coin from defeating the sensor control.

Abstract: The apparatus described measures the angle of rotation necessary to rotate a cable end from a first angular position, wherein the cores of the cable end have a certain position independent of their color, to a desired angular position, at a measuring station. The cable end is then brought into an aligning station where a rotational movement through the measured angle occurs. Subsequent to core color identification, the cable end is further turned, if required. There is provided for the scaning of the position of the cores a rotatable and axially slidably mounted scanning element which is coupled with an angle of rotation signal generator, which element contacts individual cores by means of scanning fingers or engages in the external intermediate spaces of the cores. During the scanning process the scanning element is disconnected from all drives.

Abstract: A locking device for a hydraulically operated dump truck secures the lift cylinder against unwanted oscillation when the dump body is in the lowered travel position by securing the top of the cylinder to the doghouse of the dump body. The cylinder is connected to the bottom of the dump body for lift purposes and pivots away from the doghouse during lifting.

Abstract: A bale handling apparatus for receiving, transporting, discharging, and feeding of large round bales of hay is provided. The apparatus includes an upwardly open semi-cylindrical cradle rotatably supported above a trailer frame on a scissor device attached to the trailer frame and an undercarriage slideably mounted on the trailer frame. A restraining bail is pivotally mounted to the top of the cradle for restraining the bale of hay as the cradle is rotated. A hitch mechanism is attached to the trailer for connecting the apparatus to a towing vehicle.As the invention moves in a rearward or forward direction the undercarriage slides along the frame causing the scissor to open and close, and thereby raising or lowering the cradle into engagement or disengagement with the underlying surface, causing rotation of the cradle for receiving, transporting, and discharging the bale of hay.

Abstract: A coin slide [10] is provided having an apparatus for rejecting magnetic coins and magnetic slugs and comprises a housing [11], a mounting flange [12] and a track [16]. A slide or carrier [21] is slidably received within the track [16] and has slots [23] for carrying coins standing vertically on edge along a horizontal coin path. A cylindrical permanent magnet [33] is positioned above the coin path for lifting magnetic coins and magnetic slugs at least partly out of the coin path to prevent the slide from carrying the coins farther along the coin path. An elongated cylindrical stop [34] provides a positive barrier against which magnetic coins and slugs which have been lifted by the magnet can engage to prevent further insertion of the slide [21].

Abstract: A force feeling type master/slave manipulator detects a positional difference, a speed difference, and a force difference between the master and slave machines. The position difference and force difference are combined in a weighted manner and the output is used to drive an actuator on the control lever of the master machine to provide a force feeling feedback effect. The position difference is also combined in a weighted manner with the speed difference and the speed of the working machine to provide a sum value. The load force is subtracted from the sum value and the result is used to provide a signal for driving the actuator of the working machine. As a result, stable operation of the control lever is provided, natural vibration of the working machine is reduced and the working machine is stabilized against large inertial loads.

A release lever normally abutting against the engaging bar is displaceable by a biasing force larger than the biasing force applied to the engaging bar. An operating portion for operating the release lever is connected thereto through a wire and a spring connected with the wire.

Abstract: An end effector (10) is pivotally affixed to a robot arm (12) and comprises a platform (28) and a catcher (42). In operation, the end effector (10) picks up an integrated circuit slice (S), tilts the platform (28) away from the horizontal, causing the slice (S) to slide into an indexing surface (47) of the catcher (42). This places the slice (S) in a predetermined position relative to the robot arm (12) allowing for precise placement of the slice (S) at a workstation (106).
