Abstract: Processes for the desulfurization of high end point naphtha, such as naphtha fractions having an ASTM D-86 end point of greater than 450° F., greater than 500° F., or greater than 550° F., and containing hindered sulfur compounds, are disclosed.

Abstract: The present invention is an improved slip forming device for forming a concrete curb having a desired profile. The device consists of a hopper portion and a removeable extruder portion, the extruder portion being adapted and configured to extrude the concrete curb having the desired profile. The hopper portion of the invention has a top, an open bottom, side walls and a back wall having an opening. The extruder portion of the invention has a front wall, a back wall, a closed top, and open bottom and side walls. The front wall of the extruder has a front opening and the back wall of the extruder has a rear opening, the top and side walls of the extruder forming a channel between the front and rear openings of the extruder. The rear opening of the extruder is substantially in the form of the desired profile. The front wall of the extruder is releasably mounted to the back wall of the hopper such that the front opening of the extruder is in communication with the opening of the hopper.

Abstract: A car wash wheel push roller dolly (20) is used for transporting a vehicle by pushing the vehicle wheel on a horizontal track in a car wash system consisting basically of a polyurethane dolly body (22) with an integrally formed upward portion (36) and a gusset (38) connecting the front to the rear. A front axle (40), a first rear axle (42) and a second rear axle (44) are all integrally formed with the dolly body and extend outwardly from each side of the body at right angles. Each distal end of the axles include a groove (46) adjacent to their ends. A pair of front rollers (50) are disposed on the front axle, next to a pair of conveyer chain links (48) also a pair of first rear rollers (52) and second rear rollers (54) engage their respective axles with all of the rollers attached with retaining rings (60). When a vehicle is positioned on the car wash endless chain conveyer horizontal track (58) and the chain links are attached to the endless chain, the vehicle may be pushed forward by the dolly.
