Abstract: A triangular retractable safety marker provides motorists and motorcyclists with advance warning of disabled vehicles and/or work zone areas. The device has been designed to withstand reasonable winds through the use of two base supports, a lower portion and two sets of lower, middle and upper risers. The risers allow for the device to easily expand to height consistent with traffic engineering design standards for triangles when in operation and then compact when it is in storage. The two base supports in are designed not only to provide the necessary structural stability but to also open and close about the retractable risers thus providing for additional compactness. The upper part of the lower portion along with the two sets of lower, middle and upper risers have reflective decals affixed to them to correspond with standard triangle design.

Abstract: A multi axial asphalt heater for re-heating and recycling of old and new asphalt for permanent joint free repairs and restorations. It is possible to adjust the heating elements mechanically up and down off the asphalt surface with the lever arm mechanism. The provision of rotational movement of the heating elements permits the device to be retracted into a transport configuration. Forward and reverse motion of the heating elements permits a graduate heating process to be performed. The fold-up design with radially shaped adjustable hinges provide various angularity adjustments not only for compact convenience but also for establishing specific heat clearances, avoiding shut down delays and overheating.

Abstract: A contouring device and method for contouring three-dimensionally curved surfaces includes an elongated contouring assembly that is supported at opposite ends by a pair of fluid cylinders. The fluid cylinders are controlled to raise and lower the ends of the contouring assembly independently of each other, thereby allowing the contouring assembly to create a three-dimensionally curved surface as it passes over an area to be contoured. The control of one of the fluid cylinders is based on a comparison of the measured position of a first end of the contouring assembly with a profile of the surface to be leveled that is stored in a computer memory. The measurement of the position of the first end of the contouring assembly is achieved by a tracking device which tracks the position of a target positioned on the first end of the contouring assembly and which determines the three dimensional position of the target.
