20100308641 | MINING METHODS AND SYSTEMS USING MOBILE CONVEYORS - A conveyor system for an open pit mine may include one or more conveyor lines. The conveyor lines are used to transport material from one location in the mine to another location. The material transported may be a waste material, such as overburden material, or coal. The conveyor lines may move from a first end of the pit to a distal second end. When the conveyor lines reach the second end, they may reverse direction and return towards the first end. During this reversal in direction of travel, equipment may be selectively swapped between the conveyor lines. The conveyor lines may include at least one mobile bridge conveyor. Each mobile bridge conveyor may support one or more conveyors that transport the material. | 12-09-2010 |
20110226591 | VERTICAL PIPE CONVEYOR - A pipe conveyor may include a conveyor belt formed into a pipe-like shape to define a space that contains material to be transported by the conveyor. Along at least a portion of the pipe conveyor, friction drive conveyors or friction tires may be positioned. The friction drive conveyors may include friction drive belts that engage the pipe conveyor belt. Via this engagement, the friction drive conveyors apply a force to the conveyor belt that moves the conveyor belt in a desired direction. Further, when the friction drive conveyors or friction tires are positioned within an inclined vertical section of the conveyor belt, the friction drive conveyors or friction tires vertically lift the pipe conveyor belt via pushing the conveyor belt in a vertical direction, thus assisting a drive pulley that vertically pulls the conveyor belt and material transported on the conveyor belt from a lower elevation to a higher elevation. | 09-22-2011 |
20120061211 | STEEP ANGLE PIPE CONVEYOR - An angle pipe conveyor comprises a conveyor belt or roller belt. The conveyor belt includes a first conveyor belt section and a second conveyor belt section to define a cylinder structure having an overlap thickness based on plural sections of the roller belt with an overlap structure having an oval- shaped cross section. Support elements support the conveyor belt as rollers located on the support elements guide the cylinder structure. | 03-15-2012 |
20120061212 | PIPE CONVEYORS - A conveyor system may include a pipe conveyor with a head end, a tail end, and an inclined section. The conveyor system may also include a conveyor belt comprising a first portion and a second portion, and the conveyor belt may be configured to form a pipe shape when the first and second portions of the conveyor belt are overlapped. In some embodiments, the first portion may include a first type of longitudinal reinforcement elements and the second portion may not include any of the first type of longitudinal reinforcement elements. In some embodiments, the conveyor system may include a material plug configured to circumferentially engage at least a portion of an internal surface of the conveyor belt. | 03-15-2012 |

20080216420 | Method and Apparatus for Forming Cast-In-Place Concrete Window Wells - A method and apparatus for forming cast-in-place window well walls includes first and second forming panel modules each having an inner and outer section. The forming panel modules may be connected together by a spacer panel which extends downwardly to a footing for providing a pier for supporting the window well wall. The forming panel modules are preferably configured with arcuate corners and upper and lower rails to permit stacking of the modules to increase the height of the window well wall, or include additional spacer panels or filler forms to increase the width or thickness of the window well wall. | 09-11-2008 |
20090230283 | FORM CLAMP - A form clamp particularly useful in construction environments for clamping two side-by-side forming panels is provided. The form clamp includes a frame having a first jaw and a slider having a second jaw opposed to the first jaw. The slider is shiftable along the frame, and at least one includes a locating pin configured for receipt in holes in forming panels. | 09-17-2009 |
20100242403 | MULTIPLE DIMENSION BEAM, DECK AND COLUMN SYSTEM - A method, forming panel and system provide for monolithic pouring of concrete columns, beams and elevated decks. The forming panel may be variously sized and dimensioned to serve as a beam forming member or a column forming member, and includes a frame having at least one reinforcing member having a plurality of penetration indicators which are not in registry, at least initially, with any opening in a face plate of the form. The penetration indicators serve as markers and preferably guide templates for drilling openings at preselected locations in the face plate at corresponding to the indicators. The openings so drilled are part of coupler-receiving passages, whereby forms may be variously configured in different dimensions or arrangements. The forms may be configured to provide column form assemblies, beam form assemblies, or receive floor forms in a variety of configurations, and may be readily reconfigured and reused by plugging openings which are in currently undesired locations. | 09-30-2010 |
