Abstract: A compact mobile variable angle vibrating screen with an overhead feed conveyor drive system configured to accommodate nesting into the feedbox of the vibrating screen by use of a 90-degree input shaft speed reducer; a V-belt drive and a drive shaft coupling the two and a motor mounted in front of and perpendicular to the head pulley of the feed conveyor, all arranged in a configuration to nest within a feed box of the vibrating screen and to minimize the need for offset feeding with the conveyor.

Abstract: A compact mobile variable angle vibrating screen with an overhead conveyor with an inclined bottom feed support section, an independently positionable intermediate support section, and an overhead head support section where the independently positionable intermediate support section can be relocated to a new position in response to a translation of the bottom feed support structure while maintaining an angular orientation which is half of the angle of inclination of the bottom feed structure.

Abstract: A compact mobile variable angle vibrating screen with climbing and access systems configured to accommodate variable angles and exhibit increased ease and safety for users. The system comprises a stationary ladder and ladder top platform positioned adjacent to a variable angle walkway platform, such that stepping between the platforms is a lateral step when the angle of inclination of the screen is at a halfway point between minimum and maximum inclination.

Abstract: A compact mobile variable angle vibrating screen with fines diverting systems configured to accommodate variable angles and still deliver material, via a plurality of partially nested fines chutes, to a fixed location despite angular adjustment of the vibrating screen. The system comprises a diverting pan attached to the underside and at a top end of a bottom screen and centrally positioned, such that fines material which quickly passes through the several decks encounters the diverting pan instead of falling directly onto a discharge conveyor.

Abstract: A compact mobile variable angle vibrating screen with a suspension and dampening system configured to rapidly accommodate variable angles and exhibit acceptable vibration levels; especially during power up and power down surge vibration at the variable angles. The system comprises a group of bi-directional dual pivot leg vibration damper mechanisms, including nesting tubes, one with holes for receiving pins and the other with a semi-circular cutout at the bottom edge.

Abstract: A mobile variable angle vibrating screen with the ability to process aggregate material in a horizontal orientation and at incrementally higher angles of inclination where changes in angles of inclination can be affected without the need to dismantle the vibrating screen and without the use of hand tools. The variable angle screen being configured: to blend output at all of the various operating angles of inclination, be transportable with a detachable bolt on feeder module; have an overhead feed conveyor which operates at a substantially horizontal configuration and at various operating angles of inclination.

Abstract: An HMA plant which uses incidental heating of metal surfaces in combination with hot exhaust gases to pre-heat and pre-dry virgin aggregate material contained in an enclosed container which permits hot dry air to pass through interstices in the virgin aggregate material stored in the container.

Abstract: An articulating flexible overhead boom disposed on one aggregate processing plant and configured to pivot so as to hold a power cable connecting two adjacent aggregate processing plants at an elevation above the ground so as to permit walking and/or driving a vehicle between the adjacent plants while the connection power cable remains overhead.

Abstract: A warm mix asphalt plant comprising a counter-flow drum, apparatus for precisely metering flows of A/C and water, an asphalt expander with no moving internal parts where a circular curtain of flowing clean water is mixed with a coaxial circular curtain of moving heated A/C to create asphalt foam which is heated and mixed inside a lower portion of the asphalt expander and then distributed to cover aggregate inside the counter-flow drum.

Abstract: An HMA plant which uses incidental heating of metal surfaces in combination with hot exhaust gases to pre-heat and pre-dry virgin aggregate material contained in an enclosed container which permits hot dry air to pass through interstices in the virgin aggregate material stored in the container.

Abstract: A compact modular mobile aggregate processing system configured with no stand-alone inter-plant conveyors for decreasing the footprint of the system and an infinitely adjustable flow diverter(s) for increasing the control of and variation of output characteristics of the system; the system further including specialized folding conveyors.

Abstract: An HMA plant which uses combination direct exhaust heated and indirectly steam heated pre-heating drum in combination with a sealed indirect hot oil heated rotary shaft mixer, where the steam given off from the heated HMA is maintained, separated from the sulfur containing exhaust of a hot oil heater, so as to minimize the production of acid in liquid form.

Abstract: A mobile collapsible screen and cone crusher combination where the screen is pivoted forward and downward for transport and a rubber hopper is coupled to the fines conveyor so as to permit a hinged connection and a sliding connection between the flexible hopper and the fines conveyor. A plurality of flexible matter edge plates are used at the rear of the flexible hopper to facilitate proper compression and expansion of the flexible hopper. A selectable maintenance catch is used to allow the screen to be elevated to an intermediate height for maintenance.

Abstract: A boom truck with splayed forward stabilizers which permits loads to be lifted over the front of the vehicle without a central front jack and further having a pair of rear stabilizers which are separated from the splayed forward stabilizers along a substantial length of and near the rear end of the vehicle frame. The boom truck being made in a process where the attachment of the rear stabilizers is done in a separate and distinct process from the attachment of the splayed forward stabilizers.

Abstract: A T shaped screen panel seal strip for use in spanning between screen support rails in a vibrating screen is disclosed, which has a plurality of notches therein in registration with the screen support rails so that the strip can be placed over either new or existing screen support rails (after having been cleaned of any cushioning cap material). The strip can be metallic or a plastic material. The method includes retrofitting existing screens with a new sealing strip by first removing any cushion cap material and then placing the T shaped seal strip over the support rails.

Abstract: A compact mobile variable angle vibrating screen with a suspension and dampening system configured to accommodate variable angles and exhibit acceptable vibration levels; especially during power up and power down surge vibration at the variable angles. The system comprises a group of bi-directional dual pivot leg vibration damper mechanisms which are effective only during times of excessive vibration such as during the power up and power down vibration surges.
