A conveyor includes elongated and curved first and second structural beams. Each beam includes a plurality of support tabs projecting outwardly therefrom in opposite directions and the tabs support a corresponding endless belt along the entire length thereof. The two belts operatively connect to at least one drive mechanism and define a conveying path from a first end of the beams to the opposite end. The beams are oriented such that the spacing between the two belts remains relatively uniform along the conveying path. The size, shape, orientation, and spacing of the support tabs cause the endless belts to twist in orientation, preferably by about 180&#xb0; between entrance and exit ends of the conveying path. During driving of the belts, the belts cause an article held therebetween to change angular orientation as the belts convey the article from the entrance to the exit of the conveying path.

A portable curb ramp (1) for wheeled vehicles and equipment (4) having a curb conforming contact surface (7) and a planar road contact surface (6) on an underside and a sloping top surface (5) to allow tires (3) to transverse from a road surface up and over a curb (2). The sloping top surface (5) may have a plurality of transverse ridges (8) for improved traction. The underside curb conforming contact surface (7) may have a lip which extends over the top of the curb and one or more ridges (9) on the planar contact surface to reduce slippage of the ramp on a road surface. Magnets (13) attached to the planar contact surface allows the ramp to be secured to metal surfaces (14) on the wheeled vehicle and equipment so the ramp is readily accessible. The curb conforming contact surface (7) may have two low bearing side walls (16) with a hollow cutout (12) in between in order to reduce the weight of the ramp.

A package banding machine for wrapping each of plural packages with a band. The machine includes a package conveyor for continuously moving successive packages in-line in a machine direction at a set line speed. A series of band transfer heads connected to a transfer head conveyor are provided for transferring separate package bands from a supply source into overlying proximity with each package's obverse face, the transfer head conveyor also moving at the set line speed. A band forming head is cooperatively associated with the band transfer head, the forming head functioning to deform each band around against opposed side faces of a package after the transfer head has positioned the band against the package's obverse face. The machine includes a first flap folder for folding one end of the package band against a reverse face of the package while the package is continuously moving in the machine direction, and also includes a second flap folder for folding the band's other end against the package's reverse face while the package is moving in the machine direction. Preferably the band is oriented generally parallel to the machine direction when the band is positioned against the package' s obverse face so that the first flap folder can fold the band's one end in a counter-machine direction, and so that the second flap folder can fold the band's other end in the machine direction.

There is provided a lens generating apparatus and method for generating a surface on a lens blank, or other workpiece, of a wide range of shapes utilizing rotary movement of the components without a linear way system. The lens generating apparatus includes a rotatable tool support spindle which rotates a spheric tool about a first axis. The tool spindle is directly carried by a high torque, low inertia, direct drive servo motor which rotates the first rotational axis of the spherical tool about a second rotational axis. A workpiece spindle holds the workpiece and rotates it about a third axis which generally lies in the same plane as the first axis. The workpiece spindle is rotatably supported by a second high torque, low inertia, direct drive servo motor which rotates the third rotational axis about a fourth axis. The orientation of the first and third rotational axes are controlled by a CNC computer which controls the rotation of the two direct drive servo motors in dependence upon the rotational orientation of the workpiece. The spherical tool is controlled so as to follow a predetermined three dimensional tool path relative to the lens blank.

A connecting rod fracture machine for fracture separating the caps and bodies of integrally formed connecting rod workpieces includes a cryogenic cooling station for embrittling the large ends, a fracture station for fracture separation of the embrittled cap and body portions, a warming station for returning fractured assemblies to ambient temperature and transfer mechanism for moving the workpieces between stations. The fracture station includes separable pilots for receiving the large end bores of the pieces to be fractured, an impact separation ram for rapidly separating the pilots to effect fracture separation and anti-rotation clamp means movable with the respective pilots and requiring linear separating motions of the caps from the connecting rod bodies.

Connecting rod fracture machine

A fixture and mechanism for guiding and installing body bound bolts in the bolt openings of engine connecting rods and the like. The device uses an air cylinder to advance an impact hammer driving push rods to engage the bolts. The air cylinder applies only a moderate force sufficient to advance the impact hammer to a position to impact the bolts. The impact force of the pneumatic air hammer is required to advance the bolts into press fitting engagement within the connecting rod openings. The method of using impact forces to drive the bolts into press fitting engagement while advancing the impact hammer with a lower force air cylinder accomplishes installation of the bolts with a relatively small and low cost fixture and equipment as described.
