Abstract: ABSTRACT         Disclosed is a centering and clamping device consisting of:  a disk elevator, a disk support, a disk centering assembly, a disk clamping assembly, and a disk rotating assembly.  In operation the disk is raised out of the disk insert tray cartridge by the disk elevating means and raised upward to engage a taper on the spindle of the device spin motor, moving upward until the cooperation between the taper on the spindle neck and the tapering on the disk centering collar cause the disk to move laterally until precisely centered on the spindle.  Thereafter, the continued upward movement of the disk on the elevator lifting assembly causes a magnet located on the disk support assembly to come into magnetic contact with a steel plate on the spindle platform, thereby securely clamping the disk to the spindle for rotation.  Thereafter, the elevator assembly is moved downward clamping the disk from the disk support assembly, thereby allowing free rotation of the spindle disk and disk support means relative to a stationary elevator assembly.  For removal, the above described procedure is reversed with the elevator moving slightly upward clamping into the disk support assembly, thereafter the entire assembly moving downward removing the disk from the spindle and moving further downward until the disk rests securely in a cartridge for removal from the device.

Abstract: ABSTRACT         A roller-reamer stabilizer having a plurality of roller cutters mounted in recesses in the supporting body such that each roller is free to rotate in its own bearing blocks.  The cutters and bearing blocks are provided with air bleed lubrication and cooling from a central bore in the supporting body as is common and well known in the art.  The present invention deals with the supporting body of a roller-reamer stabilizer of the near bit type and in particular one that would be used in the mining blast hole drilling industry.  This supporting body is characterized by having a profiled lower end having maximum diameter outer surfaces separated by minimum diameter relief areas.  The maximum diameter surfaces are, respectively, aligned with the cutters and extend upwardly from near the lower surface of the body to encompass the lower bearing blocks.  The minimum diameter relief areas extend further up the body and terminate level with the upper bearing blocks.  This configuration reduces the wear experienced in the vicinity of the lower bearing blocks.

Abstract: ABSTRACT     An operator for a rolling door having a curtain barrel shaft rotatable for actuating the door includes a drive gear adapted for connection to one end of the curtain barrel shaft and a second gear adapted for connection to one end of an idler roller.  The idler roller in use engages one surface of the door and extends horizontally across the top of the door opening.  A third gear is rotatably mounted in the region of the drive gear and the second gear and an electric motor is provided to rotate this third gear.  In one version of the invention there is a moveable fourth gear in meshing engagement with the third gear and driven thereby.  The fourth gear can be swung from a first position where it is in meshing engagement with the second gear to a second position where it is in meshing engagement with the drive gear.  A chain loop connectable to the door is driven when the second gear and the idler roller rotate and it is provided to close the door even under pressure.  In a second version, a floating clutch drive system employing an endless chain is employed to selectively drive either the shaft about which the door is rolled or the chain loop.

The laser beam is projected against the range of over 30% and below 80% of the thickness of the butted edges including the central portion of the thickness to melt the butted edges by the combined heating action of the laser beam and high-frequency current.  The corners are heated and melted by means of high-frequency electric resistance heating, so that the butted edges of the workpiece can be melted uniformly through the entire range of thickness.
