48657107, Sep 12, 1989

Filed:

Mar 31, 1988

Appl. No.:

7/175711

Inventors:

David B. Aaron - University City MO
John D. Wiley - Madison WI

Assignee:

Wisconsin Alumni Research Foundation - Madison WI

International Classification:

C23C 1434

US Classification:

20419212

Abstract:

A magnetron sputtering apparatus is formed with a plurality of cells each for generating an independent magnetic field within a different region in the chamber of the apparatus. Each magnetic field aids in maintaining an ion plasma in the respective region of the chamber. One of a plurality of sputtering material targets is positioned on an electrode adjacent to each region so that said ions strike the target ejecting some of the target material. By selectively generating each magnetic field, the ion plasma may be moved from region to region to sputter material from different targets. The sputtered material becomes deposited on a substrate mounted on another electrode within the chamber. The duty cycle of each cell can be dynamically varied during the deposition to produce a layer having a graded composition throughout its thickness.

International Classification:

B28C 546
B28C 702

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.

Robert Erickson - Georgetown TX

Assignee:

Cyclean, Inc. - San Fernando CA

International Classification:

B28C 546

US Classification:

366 25

Abstract:

An apparatus for the treatment of 100% reclaimed asphaltic pavement (RAP) uses low temperatures and no direct radiation from a burner flame to the RAP. The RAP is first heated in a counter flow drum which is supplied with hot combusting gases generated by a remote low NOx burner. The temperature of the drum input gases is preferably around 1100 degrees F and the output temperature of the gases may be 100 degrees F or less greater than the input temperature of the RAP. The RAP may be heated with a microwave oven to raise the RAP to a final temperature, although this step is not absolutely necessary in the counterflow design of this invention.

Mike Miles - Georgetown TX

Assignee:

Cyclean, Inc. - Round Rock TX

International Classification:

B28C 546

US Classification:

366 25

Abstract:

Apparatus which controls recycled asphalt production rate, emissions, mix and output temperature in an asphalt mixer. Computer flow charts show control decisions based upon measured parameters which include drum slope, drum RPM, gas volume into the drum, gas volume out of the drum, drum inlet gas temperature, drum outlet gas temperature, hydrocarbons in the exhaust, and recycled asphalt outlet temperature.

Assignee:

Cyclean, Inc. - Round Rock TX

International Classification:

B01D 5304

US Classification:

95117

Abstract:

An apparatus and process is provided for the production of hot mix asphalt (HMA) by the treatment of virgin material alone or adding reclaimed or recycled asphalt pavement (RAP) of up to 100% of the HMA comprised of reclaimed asphaltic pavement (RAP). 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 temperature of hot gases entering the drum is from about 400. degree. to 2,000. degree. F. , and the temperature of gases exiting from the drum is from about 130. degree. to 220. degree. F. The HMA material optionally can be subjected to microwave radiation to raise the material to a final temperature, or optionally to only reorient the dipolar molecules of the material without any measurable heating of the material. The exhaust gas is treated and made environmentally safe. The hot gases exiting from the drum are passed through a knockout box and then through a baghouse having acrylic bags coated with a protective layer of particulate material.
