Feb 25, 2005

Appl. No.:

11/067439

Inventors:

Robert W. Erickson - Georgetown TX, US

International Classification:

A01D 34/53

US Classification:

56249

Abstract:

An apparatus for cutting and clearing brush, trees and land debris includes a housing adapted for mounting to a carrier and a rotor assembly with a predetermined plurality of cutting tools mounted for rotation within the housing and driven by a gearbox and a motor combination. A tubular frame mounted to the housing above the rotor guides pushes the material for contact with the cutting tools mounted on the rotor. A movable front flange provides directional control for processed material discharge. A plurality of cutting tools are attached to a bottom portion of the housing for decreasing the size of the processed material. A plurality of a plate like members are attached to the bottom portion of the housing for limiting a size of the unprocessed material and for guiding the material into the housing for contact with stationary and rotating cutting tools. At least one deflector within the housing reduces the speed of the processed material for increased contact with the cutting tools.

Assignee:

River City Manufacturing, Inc. - Austin TX

International Classification:

E21C 35/183

US Classification:

299106

Abstract:

A cutting tool for use on earth working and land clearing equipment includes a working body portion having a cavity disposed therein which begins at a peripheral edge of a first end and extends inwardly towards a second end of such working body portion. The cavity is provided with a cutting portion disposed at an acute angle about such peripheral edge. A mounting shank extends outwardly from and is attached to the second end of the working body portion for enabling attachment of the cutting tool to a tool holder used on such earth working and land clearing equipment. At least one pin member engaging the complimentarily aligned grooves within an aperture of the tool holder and an outer surface of the shank portion is used to securely retain the cutting tool within the tool holder.

Inventors:

Robert Erickson - Georgetown TX, US

International Classification:

E21C025/10

US Classification:

299106000

Abstract:

The present invention provides an improved retaining system for securing a cutting tool to a support block. The retaining system includes at least one groove, having a first predetermined shape, formed in an outer surface of a shank portion of the cutting tool. The groove is formed in a direction transverse to a longitudinal axis of the shank. There is at least one groove, having a second predetermined shape, formed in a surface of a bore formed through an axis of the support block for receiving the shank portion of the cutting tool. The at least one groove formed in the outer surface of the shank portion of the cutting tool is radially opposed to the at least one groove formed in the surface of the bore formed through the axis of the support block when the shank portion is inserted into the bore of the support block. The final essential element of the retaining system is at least one pin member engageable with each of at least one groove formed in the outer surface of such shank portion of the cutting tool and the at least one groove formed in the surface of the bore formed through the axis of the support block for securing the cutting tool to the support block.

International Classification:

E21C 35/19

US Classification:

299106000

Abstract:

An improved retaining system for securing a cutting tool to a support block rigidly attached to an outer surface of a carrier. The retaining system includes a first groove formed in an outer surface of a shank portion of the cutting tool in a direction transverse to a longitudinal axis of the shank portion. There is a second groove formed in a surface of a bore formed through an axis of the support block for receiving the shank portion of the cutting tool and formed generally perpendicular to a rotational axis of such carrier. The first groove is radially opposed to the a second groove when the shank portion is inserted into the bore of the support block. The final essential element of the retaining system is a pin member engageable with each of the first groove and the second groove for securing the cutting tool to the support block.

US Classification:

83651, 175427

Abstract:

A cutting tool for use on earth working and land clearing equipment includes a working body portion having a continuous slot formed transversely therethrough in open communication with the first end and an exterior surface thereof. A cutting insert having a V-shaped notch formed in the front cutting end thereof is positioned and rigidly secured within the slot. A mounting shank extends outwardly from and is attached to the second end of the working body portion for enabling attachment of the cutting tool to a tool holder used on such earth working and land clearing equipment.

Abstract:

The present disclosure relates to methods and systems for developing, implementing, transforming, and governing a business model of an enterprise. In some embodiments, a method of implementing and managing a business model of an enterprise includes defining a business model using a business model tool that is executed by a computer, wherein the business model is based on interrelated business strategy, business goal and business constraint data, and includes a business service, inputting into the computer a first set of data representing a benchmark performance value of the business service, and operating the enterprise in accordance with the business model. The enterprise is monitored to determine an actual performance value of the business service, and the actual performance value and the benchmark performance value are processed in the computer to affect a comparison therebetween. The business model is modified based on the comparison.

International Classification:

B28C 546

US Classification:

366 25

Abstract:

An apparatus for controlling the angular velocity and slope angle of a hot mix asphalt drum as a function of the temperature gradient across the drum outlet. Uneven gas outlet temperature indicates that the veil of RAP (Recycled Asphalt Pavement) in the drum is insufficient. The veil is increased by increasing drum speed. The complete recycled asphalt pavement hot mix asphalt plant uses uneven gas outlet temperatures to change drum operating parameters.

Cyclean, Inc. - Round Rock TX

International Classification:

US Classification:

366 7

Abstract:

A process for the production of hot mix asphalt (HMA) by the treatment of virgin material alone or adding reclaimed or recycled asphalt pavement (RAP) (up to 100% of the HMA). The HMA is first heated in either a parallel or a counter flow rotating drum which is supplied with hot combustion gases generated by a remote low NO. sub. x burner. The process is controlled by a micro-processor which controls RAP temperature, mixture gradation, emissions and production rate as a function of measured drum conditions such as temperature at the drum inlet, drum speed, drum slope, drum RPM, output hydrocarbons, drum gas outlet temperature, and amount of aggregate added.
