Abstract: The present disclosure provides a dispensing system for a fuel additive. This dispensing system comprises two subsystems, one being located in a vehicle and the other located in a fuel pump. The dispensing system of the present disclosure dispenses a liquid fuel additive into a fuel additive storage container of a vehicle at the time the vehicle is fueled at a fuel pump. According to the present disclosure, the fuel additive is a solution of urea, water and a monohydric or polyhydric alcohol. A gasoline performance enhancer may also be used as a fuel additive in the dispensing systems of the present disclosure.

Abstract: Process and apparatus are provided for blending a fuel which includes a No. 2 fuel oil component and a No. 1 fuel oil component, with the No. 1 fuel oil component being added to provide a fuel mixture which will not freeze or form solid wax particles above a predetermined temperature. The process includes lowering a temperature of a sample of the No. 2 fuel oil component, detecting a change in wax crystal concentration of the No. 2 fuel oil component sample by detecting a predetermined rate of change in viscosity of the sample or by detecting a predetermined viscosity level of the sample as the temperature thereof is lowered, and measuring a temperature of the No. 2 fuel oil component or bath in which it is cooled, when the change in wax crystal concentration is detected. A percentage amount of the No. 1 fuel oil component to be mixed with the No.

Abstract: A hydraulic shock absorber has an adjustable connection to the exercise lever to provide variable resistive forces to exercise, and alternately the shock can be mounted to the exercise lever as a dead weight and a pulley-cord system added, so that a multiplicity of exercises can be performed with the same basic unit.

Abstract: 4.times.8 Plywood sections are interconnected by a system of tabs and latches, and a spring suspension system is provided beneath the interconnected sections.

Abstract: The invention relates to a gymnastic balance beam of extruded aluminum with a bottom and end closures. The beam is of a general U-shape with the bottom plates secured to a flanged portion of the beam. The beam can be selectively covered with padding if desired.

Abstract: The vaulting board has leaf springs with rollers at their opposite ends, and the effective length of the leaf springs can be changed by changing the roller spacing.
