For certain angular relative positions of the ring and the chuck driving element, the north poles of one are face-to-face with the south poles of the other; displacement from such position causes torque on the order of tell to twenty inch pounds to be imparted to the chuck driving element. The chuck driving element rotates with the magnet ring until the resistance of a cap being threaded on the container exceeds a predetermined torque limit, after which the magnet ring rotates relative to the essentially stationary chuck driving element. The ring magnets may be in an axially misaligned position to reduce and control maximum torque value.

Abstract: Iron ore, coal and oxygen are fed to a reactor to produce iron and a fuel gas. The fuel gas leaves the reactor at a temperature of at least 200.degree. C. and is passed through a hot filtration apparatus. The resulting hot, filtered gas then passes through a heat exchanger. A heat exchange fluid, preferably a stream of nitrogen at above ambient pressure passes through the heat exchanger countercurrently to the hot filtered as stream. The heat exchange fluid is thereby heated. The hot heat exchange fluid stream is then expanded with the performance of external work in an expansion turbine, for example it may be used in the generation of electrical power. The hot, filtered, fuel gas may be sent for power recovery downstream of the heat exchanger or may be separated into its constituent components. If the heat exchange fluid is nitrogen it may be separated from air in the same plant that is used to feed the reactor with oxygen.

Abstract: The position of the normal airflow shock pattern in the airflow inlet of a supersonic aircraft jet engine assembly is detected by a light beam position sensor assembly. A narrow band coherent source light beam is angularly transmitted across the engine assembly airflow inlet and is angularly refracted by the normal shock pattern.

Abstract: A NO.sub.x absorbent (17) is disposed in an exhaust passage of an internal combustion engine. This NO.sub.x absorbent (17) absorbs the NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (17) is lean and releases the absorbed NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (17) becomes rich. It estimates the amount of NO.sub.x absorbed in the NO.sub.x absorbent (17) from the engine load and the engine rotational speed and when the amount of the estimated NO.sub.x becomes the maximum NO.sub.x absorption capacity of the NO.sub.x absorbent (17), makes the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (17) rich.

Abstract: In an internal combustion engine equipped with a turbocharger and a compression release engine brake, excessive stress in the engine and engine brake during operation of the engine brake at relatively high engine speeds is prevented by limiting the intake manifold pressure increase produced by the turbocharger, particularly at higher engine speeds. When the engine brake is turned on, a pressure sensor is enabled to sense the gas pressure in the intake manifold. When the pressure sensor detects that the intake manifold pressure is above a predetermined threshold level, the pressure sensor applies gas from the intake manifold to a pneumatic actuator. The pneumatic actuator opens a pressure relief valve which releases gas from the intake manifold to the ambient atmosphere.
