Patent number: 4167837Abstract: A method and apparatus are disclosed for grinding a surface upon a workpiece having disparate grindability characteristics. A mechanical cam is used in the preferred embodiment to model the characteristics of a cylindrical surface and is rotated with the workpiece. The cam imparts motion to a follower which in turn imparts the motion to a pulse generator. Electrical signals which are dependent upon the angular orientation of the workpiece and the grindability characteristics of a circumferential sector of the workpiece in grinding contact with an abrasive wheel are produced by the pulse generator and used to partially control the infeed movement and the interface force between the workpiece and the abrasive wheel.Type: GrantFiled: February 6, 1978Date of Patent: September 18, 1979Assignee: Cincinnati Milacron-Heald Corp.Inventor: Herbert R. Uhtenwoldt

Patent number: 4164391Abstract: A conveyor apparatus for carrying workpieces on flat trays has two parallel chains with tray supports connected at equal intervals between the two chains. Each tray support has a clamping device for clamping and releasing flat silicone rubber covered trays against itself. Cams are located between the chains to operate the clamping device to release the tray (for travel through a separate path) at one point in travel and later (when the tray returns from its separate path) to clamp it again. The conveyor is shown as combined with up-and-down elevator means in an oven to give a boustrophedontic path to a plurality of workpieces being heated on trays in the oven: the trays are released and clamped at the entrance to and exit from the oven to allow movement of the trays by the elevators through up and down paths at the release and clamping stations.Type: GrantFiled: March 17, 1978Date of Patent: August 14, 1979Assignee: Cincinnati Milacron Inc.Inventors: Walter D. Howard, David I. McDonald

Patent number: 4163581Abstract: A base member is mounted on the driven element of a mining machine or the like. A bit holder is affixed to the base member in such a way that the bit holder may be readily removed and replaced. The base member and bit holder having cooperating abutment surfaces to sustain much of the resultant cutting forces encountered during operation. A connecting pin is provided to maintain the bit holder in position on the base member. Retaining means are provided for the connecting pin. Such retaining means are located between the ends of the connecting pin so as to lock the connecting pin in position without having to have either the connecting pin or the retaining means extend laterally from the joined bit holder and base member. The connecting pin and its retaining means may readily be removed when it is time to replace the bit holder.Type: GrantFiled: May 4, 1977Date of Patent: August 7, 1979Assignee: The Cincinnati Mine Machinery Co.Inventor: Claude B. Krekeler

Patent number: 4133625Abstract: A machine for automatically forging and thermoforming of hollow thermoplastic biaxially oriented articles has a carrier assembly to carry, lock and unlock forging dies, indexing means to move the carrier assembly and dies past a series of work stations, and an article unloading means. Three work stations are in the automatic machine: forging where the die parts are locked together and the workpiece is forged into engagement with the die; thermoforming to which the die with the workpiece (now called a preform) gripped therein is moved into register with thermoforming mold means; and article ejecting means which include mechanical means for unlocking the die and removing the hollow article therefrom. The carrier assembly is so supported that the strains of forging and thermoforming are taken up by frame tie rods rather than the die mounting means.Type: GrantFiled: August 2, 1977Date of Patent: January 9, 1979Assignee: Cincinnati Milacron Inc.Inventors: Arnold L. Kellermann, David I. McDonald

Patent number: 4123642Abstract: Apparatus for obtaining full tooth width induction hardening of gear teeth. The method comprises attaching gear teeth shaped non-magnetic material templates to the opposite sides of the gears in close proximity to but spaced from the sides of the gear teeth. The gear teeth are then progressively induction hardened by passing a current intensifier between the aligned teeth of the templates and the gears while maintaining current flow to the intensifier for the full width of travel of the intensifier between the gear teeth. In the preferred embodiment the faces and roots of the templates are slightly undersize relative to the faces and roots of the gear teeth and the tops of the teeth of the template are slightly oversize and extend beyond the tips of the teeth of the gear.Type: GrantFiled: December 13, 1976Date of Patent: October 31, 1978Assignees: Cincinnati Steel Treating Company, General Electric CompanyInventors: Howard W. Dammel, Robert M. Frantz, James H. Luke, William G. Skrzypczyk

Patent number: 4121142Abstract: The present invention is a DC motor drive circuit in which each end of a center tapped supply transformer is connected through a pair of back-to-back thyristors to corresponding ends of a center tapped choke coil. The motor armature is connected between the two center taps. After each zero crossing of an AC input signal, a ramp signal is generated. The ramp is comprised of two linear segments of different slopes to improve the linearity of the output of the thyristors as the conduction angle approaches the zero crossing point. Comparator circuits are responsive to the ramp signal and a command signal for generating trigger pulses to the thyristors. The comparators are biased so that with no command signal present, the comparators operate the thyristors to produce a small alternating loop current through the transformer and the choke with each half cycle of the AC input signal. This maintains conduction through all the thyristors without dithering the motor armature.Type: GrantFiled: September 20, 1977Date of Patent: October 17, 1978Assignee: Cincinnati Milacron Inc.Inventors: Alfred Harold Morser, Roy Gibson, Paul Szekely, Bruce Trayton Parker

Patent number: RE30016Abstract: A method and apparatus are disclosed for modifying command signals representing predetermined positions of a machine element relative a workpiece as a function of measurable unprogrammed changes in the relative position therebetween. The machine element is responsive to a servomechanism circuit which in turn responds to a control device producing the command signals to command motion of the machine element to programmed points relative to the workpiece. The servomechanism circuit produces interrupt signals for transferring the command signals thereto. A measuring circuit is responsive to the unprogrammed change in relative position between the machine element and the workpiece and is operative to produce feedback signals representing the direction and magnitude of the change in relative position. A first circuit is responsive to the measuring circuit for producing a first signal representing a current unprogrammed change in relative position with reference to a predetermined point.Type: GrantFiled: October 19, 1977Date of Patent: May 29, 1979Assignee: Cincinnati Milacron Inc.Inventor: Richard E. Hohn
