Patent number: 8056985Abstract: A vibratory milling machine has a vibratory housing confined to substantially linear reciprocating motion relative to a base, causing a tool carried by the housing to impact a mineral formation or other work piece substantially in a primary milling direction. The vibratory motion may be generated by two or more eccentrically-weighted rotors rotated by a common drive mechanism. The rotors may be arranged in pairs with the rotors of each pair rotating in opposite directions about parallel axes so that lateral oscillations cancel and longitudinal vibrations in the milling direction reinforce one another. In one embodiment, a hydrostatic fluid bearing is provided between the outer surface of each rotor and the housing.Type: GrantFiled: October 22, 2010Date of Patent: November 15, 2011Assignee: Longyear TM, Inc.Inventors: Jing James Yao, Robert Eugene Able, Louis E. Silay

Patent number: 6921230Abstract: Apparatus and methods for controlling the operation of a pavement surfacing machine are described. One embodiment that controls a pavement surfacing machine having a vehicle moveable in a preselected direction of travel along a pavement surface under the influence of a prime mover and configured to urge a rotatable grinding head against the pavement surface includes at least one sensor configured to measure a preselected operational parameter of the pavement surfacing machine and provide an output representative of the parameter and a controller that is configured to control the rate at which the vehicle moves in response to the sensor output.Type: GrantFiled: December 24, 2002Date of Patent: July 26, 2005Assignee: Diamond Products, LimitedInventor: Louis E. Silay

Patent number: 6615931Abstract: A continuous feed drilling system and controller includes a head assembly having first and second chucks synchronized to rotate at the same rotational velocity. The chucks are independently moveable within the head assembly and their positions are measured by linear transducers. The controller causes the first chuck to engage with a drill stem and begin rotating and advancing. The controller uses the outputs of the linear transducers to determine the linear velocity of the advancing first chuck and synchronize the linear velocity of the first and second chucks. The controller then causes the second chuck to engage the drill stem and causes the first chuck to release the drill stem. The process is repeated, alternating the roles of the first and second chucks, thus creating a continuous drilling motion.Type: GrantFiled: January 7, 2002Date of Patent: September 9, 2003Assignee: Boart Longyear Co.Inventors: William V. Dycus, Louis E. Silay

Patent number: 6186248Abstract: A closed loop control system for a core drilling mechanism automatically controls the penetration rate, the weight on the drill bit, and the torque load applied to the drill string, and maintains all three at or below preselected maximum values. The closed loop control system incorporates a controller that receives sensed information and generates corresponding control signals to control the penetration rate and thus the weight on the drill bit and the torque load through a servo valve in a hydraulic drive circuit. One or more sensors are provided to sense the penetration rate of the drill bit, and are coupled with the controller. Similarly, sensors are provided to determine the weight on the drill bit and the torque load applied to the drill string.Type: GrantFiled: October 22, 1998Date of Patent: February 13, 2001Assignee: Boart Longyear CompanyInventors: Louis E. Silay, Raymond B. McKinley

Patent number: 4588231Abstract: Road or pavement surfacing machine which is towed to and from a work site by a truck tractor or the like and is self-propelled by power driven traction wheels on the machine during road or pavement surfacing operation. The traction wheels and the road or pavement surfacing cutter means of the machine are independently vertically adjustable relative to the main load supporting wheels of the machine, and hence relative to one another, by hydraulic actuator means for the cutter means and additional hydraulic actuator means for the traction wheels.Type: GrantFiled: August 28, 1984Date of Patent: May 13, 1986Assignee: Concrete Safety Equipment, Inc.Inventors: Louis E. Silay, James S. Stein, John J. Kunzweiler
