  • Truck for railway vehicle
    Patent number: 4776283
    Abstract: In a truck for a railway vehicle having a plurality of wheels-and-axles, an arrangement is provided for permitting each wheel-and-axle an optimal steering operation when the truck runs on a curved track, and to simplify the construction of journal box locator. Each journal box is located and fitted to a truck frame by the journal box locator for locating and fitting the journal box to the truck frame in such a fashion that the orbit of movement of the journal box expands upward with respect to the center axis of the truck, and permits the relative displacement between the journal box and the truck frame by elastic deformation of elastic members.

  • Articulated link for the connection of two ends of the track of a tracked vehicle
    Patent number: 4775198
    Abstract: An articulated element of a track comprising two parallel faces consisting of two superimposed parts with holes for articulation bolts. The contact sides of the articulation parts have teeth which mesh with one another and move parallel to the pivoting plane. To lengthen the articulation element, the teeth move transversely and are undercut in such a way that under the effect of a tractional force they bring together the parts of the faces of the articulation elements. To facilitate the manufacture of this articulation element and to reduce its cost, the flanks (9,10) of the teeth (5) and the toothspaces (1) are straight over the whole of their length and end freely on their longitudinal side (7 and 8).

  • Wafer handler
    Patent number: 4773687
    Abstract: A wafer handling technique allows for picking up a wafer from its front side. One or more vacuum ports pull the periphery of the wafer into contact with a ledge raised from a broad surface, providing a friction force that prevents lateral movement of the wafer. A port in the broad surface of the handler flows pressurized gas onto the wafer, thereby preventing contact between the handler and the interior of the wafer. The handler may be sized to be relatively thin, and to cover less than half of the surface of the wafer, thereby allowing for readily loading wafers back-to-back in a furnace boat.

  • Robotic end of arm tooling internal gripper
    Patent number: 4770456
    Abstract: The present invention provides an end of arm tooling (EOAT) internal gripper device for a robot. The EOAT of the present invention provides a gripper portion which can be elastically deformed by being extended or retracted by an internal rod actuator. Extension of the actuator rod causes the gripper portion to assume a smaller dimensional shape for insertion into a workpiece cavity. Retraction of the actuator rod causes the gripper portion to increase in dimension therefore engaging and gripping the workpiece. The EOAT of the present invention is extremely useful in applications requiring large amounts of compliance, delicate handling, and/or in environments wherein an air supply is not available or desirable.

  • Passively activated prehensile digit for a robotic end effector
    Patent number: 4770455
    Abstract: A common hydraulic reservoir holds one or more rows of slidable pistons or "fingers" in a base, or "hand". The individual fingers in each row expose graduated cross-sectional fluid application areas to the hydraulic fluid in the reservoir, with the smallest fluid application area in the center of the row and graduating to progressive larger fluid areas towards both ends of each row. The fingers are elongated pistons. Exposed outer ends of each piston extending away from the reservoir, house a transverse pad to contact an object to be held. The transverse pads are universally ball-joint and spring-center mounted in a longitudinally located opening at the outer tapered end of each finger. Simple and effective capacitance metering in the reservoir is provided for each finger.

  • Holding device for pick-up, transport, and deposit of small components
    Patent number: 4770454
    Abstract: The invention refers to a holding device consisting of holding head and holding shaft for pick-up, transport, and targeted deposit of small components, namely preferably for supplying circuit boards with electrical SMD switching elements.According to the invention, the holding head is designed so that upon a pressure in the direction of the components to be picked up, a bistable switching element is activated and consequently, the adhesion of the component as well, and upon the next pressure in the same direction, it is again deactivated. This saves specific control actions to activate and deactivate a compressed air source or other adhesive devices.

  • Cable catch, clamp and cut (grapple)
    Patent number: 4768820
    Abstract: A grapple of rugged construction capable of being towed along the ocean bed for recovery of underwater communication cables; having a scoop with suitable inserts to furrow and "scoop up" cable. Guided, cable is forced into a "floating" and "stationary" clamping assembly. Cable tension acts against a spring-loaded trigger releasing liquid/gas actuating a "wedge/block" via a gas cylinder and piston. The "wedge/block" driven between "floating clamps" having interchangeable inserts, firmly clamps the cable. A signal is transmitted. If the cable is to be uncut the CCC&C is hauled aboard tow vessel, cable intact. If desired to cut cable on a particular side of CCC&C before recovery, diagonally-opposed knives and liquid/gas cylinders are pre-set before submergence. Cutting is accomplished by release of liquid/gas to "hydraulic fluid/gas cylinders" with free-floating pistons.
