Abstract: An efficient high-temperature water vapor generator is used to de-contaminate soil. The vapor generator includes a combustion chamber and a surrounding structure, wherein a cavity is located therebetween. Water is routed through the cavity and into the combustion chamber, where water vapor and heat are generated in the presence of fuel, ignition and air. The generated heat pre-heats the water in the cavity, thereby creating an efficient system. The water vapor is forced into a vapor tube (which has openings for emitting the vapor), thereby heating the vapor tube to temperatures of 800° F. or greater. A soil tube having lifting paddles located therein surrounds the vapor tube. Contaminated soil enters one end of the soil tube. The soil tube is rotated, thereby moving the contaminated soil into contact with the vapor tube (decontaminating the soil). The lifting paddles move the soil toward the second end of the rotating soil tube.

Abstract: A system for continuously varying valve-opening overlap in reciprocating internal combustion engines changes the path of the timing belt (16) that drives the intake valve camshaft (26). An idler wheel (44) mounted on a pivoted arm (48) turns against the timing belt. At low engine speeds, the sprocket wheel idles against the timing belt. At higher engine speeds, increased engine oil pressure causes a hydraulic cylinder (58) to force the sprocket wheel against the timing belt, changing its path. As the path of the belt is changed, the intake valve position is advanced with respect to the position of the crankshaft (12). The exhaust valve position remains the same relative to that of the crankshaft. Thus at above-idle speeds, intake-exhaust valve overlap is present. Since the amount of belt path deviation is related to engine oil pressure, and thus engine speed, valve overlap varies smoothly as a function of engine speed. A tensioner (30) maintains proper belt tensioning at all times.

Abstract: An internal combustion engine having a camshaft which is translatable between first and second positions to control an engine operating characteristic. The camshaft is rotationally driven from the engine crankshaft, and includes an oil pump member in fluid communication with the oil sump of the engine. During rotation of the camshaft, the oil pump member pumps oil from the oil sump to various lubrication points in the engine, and also generates an oil pressure which acts upon at least a portion of the camshaft. At low engine speeds, the oil pressure is insufficient to translate the camshaft. However, at high engine speeds, the oil pressure is sufficient to translate the camshaft axially during running of the engine, and the camshaft returns to its initial position when the speed of the engine decreases. Translation of the camshaft may facilitate an automatic compression and/or vacuum release feature, a low and high speed cam switching feature, or a low oil shutdown feature, for example.
