International Classification:

E21C 25/00

US Classification:

404 90, 404 94, 299 411, 175 15

Abstract:

A method and apparatus for working asphalt pavement, comprising one or both of a mechanical, hydraulic, electric, or pneumatic means for providing high-speed rotation; a rotary tool comprising a first end comprising a working surface and a second end adapted for connection to the means for providing high-speed rotation; and a screed, cooperatively arranged with the rotary tool, and comprising a working surface adjacent the working surface of the rotary tool, wherein the rotary tool is spun at high speed and applied to the asphalt pavement, frictionally heating the asphalt pavement to a temperature sufficient to work the pavement locally adjacent rotary tool and the screed. The screed and rotary tool comprising abrasion resistant materials selected from the group consisting of high-strength steel, hardened alloys, cemented metal carbide, polycrystalline diamond, and cubic boron nitride. The rotary tool and the screed apparatus may comprise a closed loop control system.

Robert P. Chase - Provo UT, US

International Classification:

E21C 3/00

US Classification:

299100, 299 70

Abstract:

A formation breaking apparatus with increased wear-resistance is disclosed. In one aspect of the invention, the apparatus has an assembly attached to an end of an articulated arm. The assembly has an actuator in mechanical communication with an axially guided penetrator. The penetrator may have a body intermediate a proximate end and a distal end; the proximate end being adapted to communicate with the actuator, and the distal end comprising a hard material with a hardness of at least 63 HRc.

Appl. No.:

8/806852

Inventors:

Robert B. Chase - San Diego CA

International Classification:

H01M 1046

US Classification:

320104

Abstract:

A system for "refueling" an electric vehicle includes a traction battery on a tray that is slidably disposed in a battery compartment of the vehicle and that is electrically connected to the traction motor of the vehicle. When the battery is depleted, the vehicle stops at an energy replenishment center which stores charged replacement traction batteries. The traction battery is electrically disengaged from the motor and the tray in the vehicle is slid out of the vehicle onto a dolly or into a receptacle of a carousel. Then, the replacement battery tray, which is disposed on another dolly or in another receptacle of the carousel, is juxtaposed with the battery compartment and slid into the compartment. Next, the fresh battery is electrically engaged with the motor, and the vehicle quickly resumes its journey. The depleted battery is recharged at the energy replenishment center and reused on a subsequent vehicle.
