Abstract: A fuel gel including an alcohol, a nontoxic denaturant, a thickening agent, and at least one neutralizing agent is disclosed. An exemplary formulation includes corn-based ethanol, denatonium benzoate, acrylic acid homopolymers, diisopropanolamine, corn-based glycerin, and distilled water.

Abstract: A biodiesel candle formed of a wick and a fuel composition having at least one fatty acid methyl ester, at least one antioxidant, and at least one chelating agent. The biodiesel candle may further include at least one monobasic ester, at least one secondary alcohol, and/or at least one additional fuel, such as mineral oil. The resulting candle features a reduced production of incombustible free radical polymers during use.

Abstract: The invention is a conveyor control system having self-propelled vehicles having wheels, each driven by a motor (14) to move along rails. The system includes power rails (18) for supplying power to the vehicle (12) and at least one command rail (20, 21) which transmits a constant command signal indicative of requested speed. The command rail (20) is comprised of isolated sections of rail for carrying different command signals along each isolated section to enable the vehicle (12) to travel at different speeds dependent on which section of rail the vehicle is within. The command signal may be in the form of an analog signal on one rail (20) or a digital signal on two rails (20, 21). Each vehicle (12) includes a control circuit (22) which interprets the command signal to drive the vehicle (12) at the requested speed. An override circuit (28, FIG. 2b, FIGS. 3 and 4) senses external activity for proper control of the circuit.

Abstract: The invention is a conveyor assembly (10) having a vehicle (12) which moves about a track (18). The track (18) includes rails (20) extending therealong for supplying power and command signals to the vehicle (12). The rails (20) are separated into isolated sections separated by buffers (24) with each section supplying electrical signals. The vehicle (12) includes at least two contacting pads (32, 33) for contacting a rail (20) and conducting the electrical signal on the rail (20) to the vehicle (12). The contracting pads are spaced a distance such that at least one contacting pad (32, 33) is in electrical connection with the rail (20) so that the vehicle (12) continuously receives the electrical signals. The receiver (34) of the vehicle (12) receives the signals from both contacting pads (32, 33) and combines the signals while preventing back feeding to the other contact pad (32, 33).
