Abstract: Products containing carbon fibrils having a morphology of vermicular tubes that are free of a continuous thermal carbon overcoat and have graphitic layers, wherein the length of the projection of the graphitic layers on the fibril axis extends along the axis for a distance of at least two fibril diameters. The fibrils are used to form composites, adsorbents and mats.

Abstract: A method of forming and using a metal I-beam includes hot rolling an elongated metal workpiece to establish a web and a pair of flanges on the edges thereof. The web is formed with elongated reinforcement of solid cross-section having a generally straight longitudinal axis oriented generally parallel to the flanges. The hot rolled I-beam is cooled without forming substantial waves in the web and the I-beam is subsequently secured in a building construction or other structural product. The method involves the longitudinally oriented reinforcing means which preferably are one or more elongated laterally projecting ribs having such mass that the average temperature of the web prior to cooling will be sufficiently close to the average temperature of the flanges prior to cooling that the formation of waves within the web during cooling will be resisted. The reinforcement if preferably coextensive with the I-beam. The web is preferably substantially continuous.

Abstract: A volume of carbon fibrils that includes a multiplicity of fibrils having a morphology consisting of vermicular tubes that are free of a continuous thermal carbon overcoat and have graphite layers that are substantially parallel to the fibril axis and a process for preparing such fibrils.

Abstract: A berm clearing attachment for removable securement to a road clearing vehicle, such as a bulldozer, road grader, hi-lift, dump truck, tractor, or skid-steer loader, for side or lateral dozing accumulated dirt and debris off of roads and road berms and away from guiderails by reciprocating laterally with respect to the longitudinal axis of the road clearing vehicle as the vehicle travels on the road and road berm. The berm clearing attachment includes a support framework removably securable to the front of the road clearing vehicle, and when used with the skid loader, the support framework would be removably securable to the front mounting plate of the loader.
