| 20090154994 | Computer Assisted Driving Of Vehicles - Disclosed herein is a system and method for computer assisted driving of vehicles. The system disclosed herein provides an array of sensors positioned in the vehicles at strategic points for capturing vibrations and sound induced, when the vehicles move over pavement surfaces marked with predefined patterns of peaks and troughs. The sensors further measure frequencies of these vibrations. An onboard computer on the vehicle matches the captured frequencies and sound against pre-specified frequencies to obtain unique frequency signatures for the segment of the pavement traversed by the vehicle. Navigational data and geographical data associated with the unique frequency signature are used to provide assistance in driving of vehicles. | 06-18-2009 |
| 20100158609 | Permeable Paver And Manufacturing Method Therefor - A permeable paver having water permeability of on average about 1 inch per hour and compressive strength of an average of about 8000 psi, the paver manufactured by forming the mixture into predetermined sizes, shapes and colors as desired, utilizing a hydraulic-type or equivalent compacting block forming machine. | 06-24-2010 |
| 20110013985 | Apparatus for shaping pavement - An apparatus for shaping pavement, the apparatus comprising: a pavement-shaping member for receiving a flow of shapeless pavement material and generating a flow of shaped pavement material; and a paving machine mount, operably coupled to the pavement-shaping member, for coupling the pavement-shaping member to a paving machine, the pavement-shaping member comprising a concave pavement-shaping surface being disposed at a pavement ramp angle less than about 45 degrees and having a single radius of curvature less than about 60 inches. | 01-20-2011 |
| 20140154010 | PAVEMENT EDGE FORMING APPARATUS FOR PAVING MACHINE - A paving machine includes a screed. The screed further includes an endgate, a mount, a platform, and a pavement edge forming member. The pavement edge forming member has a longitudinal member and a shaping plate coupled to the longitudinal member and is inclined at an angle to a non-paved surface. The shaping plate is configured to form a ramped surface between a mat and the non-paved surface. | 06-05-2014 |
| 20150078824 | ADJUSTABLE EDGE FORMING APPARATUS FOR PAVING MACHINE - An edge forming apparatus for a paving machine forms margins of road paving materials concomitantly with a paving operation. A tube member having a slidably engaged elongated member is included. Lock plates, having lock-plate openings, are positionably engaged with the elongated member. A shaping plate is adjustably coupled with the lock plates and includes offset strips, with apertures, fixedly attached thereto. An offset pin is selectively positioned in the lock plates and extends through the lock-plate openings and the apertures. The lock plates are positionably movable with the elongated member, positioning the shaping plate in one of a retracted position and an angled position. The shaping plate is restricted from substantial rotation through an engagement of the shaping plate with the tube member through a non-rotatable fit between the tube member and the elongated member in response to contact between the shaping plate and the road paving materials. | 03-19-2015 |
| 404097000 | Manually propelled | 2 |
| 20090297269 | MOTOR-POWERED, POLE-MOUNTED CONCRETE FINISHER - A motor-powered concrete finisher, having a motor and a rotatable circular disc powered by the motor are attached at the end of a counter-balanced extension pole. A handle may be provided at or near the balance point of the extension pole. The motor may be disposed on the rear end of the extension pole, to assist in counterbalancing the weight of the circular disc, hub, front end of the extension pole and other weight on the front end of the extension pole. An angled gear drive on the front end of the extension pole, driven by a shaft extending through the extension pole, has an attachment hub at its end for attachment of the circular disc. The motor may be an internal combustion engine. The concrete finisher may be a weed trimmer having the weed trimmer attachment replaced by a rotatable circular disc. | 12-03-2009 |
| 20140105683 | MULTIPLE-AUGER CURB FORMING AND EXTRUDING APPARATUS - A manually operable and steerable curb extrusion device for extruding curb, barrier, wall, gutter or the like from concrete, cement or some other moldable building material. The curb extrusion device has a segmented vibrating hopper into which building materials are placed to fall onto a plurality of tapered counter rotating vibrating augers which compact and force the building material through an extrusion mold where it is shaped before extrusion; the number of augers adjustable and selected to provide the amount of building material required to be extruded. | 04-17-2014 |
| 404098000 | Curb or gutter | 4 |
| 20100021235 | Curb and Gutter Forming Machine - A curb forming machine for use by a single operator to form curved curbing includes a single rotatable curb-forming roller, a handle assembly for pulling and maneuvering the roller, and a motor for rotating the roller. The roller includes a generally cylindrical body, a neck at one end of the body, and a shaping surface, all of which are coaxial. The motor rotates the roller so that the lower periphery of the roller moves toward the direction of pulling to shape and smooth wet concrete into curbing. An overflow guard prevents wet concrete from flowing over the roller onto the finished curb, and an alignment device extends outwardly from the roller to contact a form member. A curb forming method includes pulling and steering such a roller around a curved form, including around tight curves in the form. | 01-28-2010 |
| 20120009014 | Hand-operated concrete curb forming machine - A hand-controlled, curb forming machine that is transformable between different widths and geometries, and between different wheel configurations, to accommodate different concrete curbing. A downwardly projecting, rotating head that rotates about an axis perpendicular to the slab shapes raw concrete into appropriately styled and contoured curbs. A machine frame slidably receives an adjustable, wheeled subframe. A roller on the opposite frame side rides on an opposite curb form. A pivoted handle is reversible. The electric motor is adjustably secured to the frame by a mounting plate movable within follower slots in the frame. A removable adaptor plate disposed on an opposite frame end supports the machine when not in use, but can be removed for normal curb work exposing a form riding roller. When the machine is deployed with monolithic curbs without rebar, the adaptor plate can mount to the subframe to raise the machine by lowering the wheels. | 01-12-2012 |
| 20140377002 | CURB FORMING MACHINE - A curb forming machine with parts which may be mounted in different positions on a frame so that curb may be laid on the left or right side of the frame outside the frame, and on the left or right side inside the frame. A feed hopper delivers curb forming material either directly to an auger housing, for curb formed inside the frame sidewalls, or first to a side chute and then to the auger housing, for curb formed outside the frame sidewalls. A curb forming mold is attached to the auger housing. Adjustable height wheels allow the machine to move along a surface for forming curb. | 12-25-2014 |
| 20150354149 | Frame Width Adjustment By Steering - A self-propelled construction machine includes machine frame that is laterally extendible to adjust a width of the machine frame. A frame lock can selectively lock and unlock the machine frame to permit the width adjustment. A controller includes a frame extension mode configured to steer at least one ground engaging unit to provide a lateral force to adjust the width of the machine frame as the machine is driven across the ground surface by the ground engaging units. | 12-10-2015 |
