Abstract: A die transfer system for transferring workpieces through successive dies stations in a stamping press includes an elongated finger bar having spaced fingers for engaging workpieces at successive die stations. A drive module for reciprocating the finger bar laterally into and out of engagement with the workpieces at the die stations, and for lifting the workpieces above the level of the die stations for longitudinal transfer between die stations. The drive module has a crank arm coupled to the drive shaft for rotating the crank arm about an axis parallel to the finger bar. A cam plate is coupled to the finger bar and mounted for movement lateral to the crank arm axis and the finger bar. A cam follower is mounted on the crank arm and disposed in a slot on the cam plate, such that rotation of the drive shaft rotates the crank arm and propels the cam follower along the slot to move the cam plate and finger bar horizontally and vertically in sequence.

Abstract: Apparatus for preventing runaway of trolleys in a power-and-free conveyor system that includes a friction bar that extends lengthwise of the free conveyor track on a side of the track remote from the power conveyor for motion lengthwise of the track at an acute angle to the direction of motion of the trolleys along the track. The friction bar is releasably biased laterally outwardly from the track and in a direction lengthwise of the track opposed to the direction of trolley motion on the track so that trolleys may travel freely along the free conveyor track past the bar.

Abstract: An above ground storage container assembly comprises a steel tank for volatile liquid housed within a concrete vault. The walls of the vault are spaced from the tank to provide an air envelop around the tank. The air envelop is vented to prevent the tank from rusting or corroding. Lifting bars are anchored in the vault so that the entire assembly may be raised. A spill trap surrounds the fill opening from the tank and also surrounds a drain hole with removable plug.

Abstract: A power drive unit for aircraft cargo handling systems that includes an electric motor and a drive roller mounted on for rotation about an axis parallel to the motor output shaft for engagement with cargo to be driven by the unit. A planetary gear differential and a torque control arrangement couple the motor output shaft to a self-erecting mechanism for lifting the unit into engagement with cargo, and to the drive roller for propelling the cargo. A scrub sensor is coupled to the drive roller for modulating application of electrical power to the motor when the drive roller is scrubbing against cargo engaged by the roller.

Abstract: An improved wheel disc and disc and and rim wheel assembly, and method and press apparatus for manufacturing the same. The wheel disc is adapted for telescopic press fit precision mounting into a mating wheel rim to form the wheel assembly. A flat disc blank is progressively die formed into a disc preform having a cross-sectional contour proximating that of the finished disc. The disc preform is then placed in a segmental expand punch and die tooling of the press apparatus which operates to apply radial expansion pressure to substantially the entire inner circumference of the peripheral flange portion of the disc preform to thereby permanently deform the same into a finished flange portion on the disc having precision finished predetermined dimensions.

Abstract: There is disclosed an apparatus for use in a bag forming/filling/sealing machine for controlling the operations of a film transportation motor (10) and an article transportation motor (18) based on the operation of a sealer driving motor (25) which is driven at a cyclic variable speed. The rotation cycles of the respective motors (10, 18, 25) are determined, based on a reference pulse which is generated by a crystal oscillator (28) and input to a central processing unit (27). When a value of the length of articles (19) to be packaged is input to the central processing unit (27), the central processing unit (27) specifies constant speeds of the film transportation motor (10) and the article transportation motor (18) and a cyclic variable speed of the sealer driving motor (25).

Abstract: A force motivating a strut to incline itself in the running direction (front-and-rear direction) of a movable main body is produced by impact stress caused by accelerating, decelerating or stopping the operation of a delivery device. Such force can securely be received by a bottom frame structure as well as by a reinforcing structure of the portions of projected corner members protruding in the running direction which are formed integrally with a cylindrical body of the strut at respective corners thereof. A force motivating the strut to incline itself in the direction orthogonal to the running direction is produced by inward/outward load delivery operation by means of a delivery instrument provided on a carriage. Such force can also securely be received by the bottom frame structure as well as by the reinforcing structure of the portions of the projected corner members protruding in the orthogonal direction.

Abstract: The subject matter of this invention relates to a method of making glass fiber mat reinforcement material with a thermoplastic adhesive powder. Fiberglass strands are chopped and randomly air dropped onto a Teflon.RTM. coated conveyor belt to form a loose mat. A water mist is then applied to the loose mat and transport belt, before a powdered adhesive is dispensed. Heat is applied to plasticize the adhesive and finally the adhesive is solidified by cooling. The adhesive will then release from the transport belt and is adhered to the material forming the fiberglass reinforcement mat.

Abstract: A die transfer system for transferring workpieces through successive die stations in a stamping press includes an enlongated finger bar having spaced fingers for engaging workpices at successive die stations, a first drive mechanism for reociprocating the finger bar longitudinally for transferring workpieces between successive die stations, and a second drive mechanism for reciprocating the finger bar laterally into and out of engagment with the workpieces at the die stations. The second drive mechanism has at least two finger bar drive modules coupled to the finger bar and spaced from each other lengthwise of the finger bar. A drive shaft extends between and interconnects the two drive modules. Each of the drive modules has a crank arm coupled to the drive shaft for rotating the crank arm about an axis parallel the finger bar. A cam plate is coupled to the finger bar and mounted for movement lateral to the crank arm axis and the finger bar.

Abstract: In accordance with the present invention, a novel composite prosthesis comprises a vein and a cylindrical-shaped member. The vein is a vein segment removed from a patient and the cylindrical-shaped member, preferably an expandable stent, is glued, sutured, or in some other fashion affixed to the outside surface of the vein. The vein segment of the combination is referred to as a vein graft or vein implant to distinguish it from the vascular structure into which it is inserted as a part of the combination. This composite prosthesis is then introduced inside a body passageway, such as diseased arterial segment or inside a saphenous vein graft segment which by-passes an arterial segment. It may be introduced by placement over a balloon catheter. When the balloon is inflated the stent and vein graft expand. The stent prevents recoil and keeps the vein graft tissue in place, while the vein graft forms a new inner lining for the vessel.

Abstract: In one method of making the wheel the parts are temporarily assembled in a fixture with the connector flanges movably engaged with one another, and the center part is precision located relative to the rim in a predetermined orientation relative to the rim bead seats by bodily shifting of the center part as and if necessary relative to the rim to accomplish such alignment. The parts are then permanently assembled in fixed relationship while so located by permanently securing the connector flanges together in a non-take-apart mode to provide a final predetermined permanently fixed orientation of the center part relative to the rim bead seats.
