  • Publication number: 20080245128
    Abstract: An apparatus for forming a metal reinforcing bar incorporates a multi stage forming line forming a termination on an enlarged end portion of the bar. The termination is shaped to form part of an interlock to connect the bar to another member. In one form, the forming line includes a forming station where the termination is at least partially formed by a forging process.

  • Patent number: 6038489
    Abstract: In a machine tool, a component such as a grinding wheel acts on a workpiece to form the latter into a circularly asymmetric shape, for example, a crankpin. Movement of the grinding wheel is controlled by a control signal which is derived from theoretical relative positions and positional velocities of the grinding wheel relative to the workpiece. In the course of at least one revolution of the workpiece, the respective positions of the grinding wheel relative to the workpiece are measured for each of a succession of angular positions of the workpiece. The measured positions are compared with corresponding theoretical positions and data indicative of any differences are stored, and then used to modify the control signal during a subsequent revolution of the workpiece so as to compensate for any of said differences and thereby reduce the magnitude of any error which would have resulted from the measured positional differences.

  • Patent number: 5702226
    Abstract: The present invention relates to a tire dolly (10) comprising a cross member (12) which comprises a cross member axle (12A). The cross member (12) further comprises a cross member left tire (12CL) securely mounted on a left distal end of the cross member axle (12A) by a cross member left axle cap (12AL) and a cross member right tire (12CR) securely mounted on a right distal end of the cross member axle (12A) by a cross member right axle cap (12AR). The tire dolly (10) further comprises a left fork (14L) which comprises a left fork shaft (14LA) securely mounted at an inner distal end onto the cross member (12). The left fork (14L) further comprises a left fork roller (14LB) rotatably longitudinally disposed upon the left fork shaft (14LA). The left fork (14L) further comprises a left fork cap (14LD) securely mounted at an outer distal end of the left fork shaft (14LA) functioning to retain the left fork roller (14LB) thereon.
