Abstract: An engine controller executes the feedback control of an amount of the fuel injected, such that an air-fuel ratio (A/F) of the exhaust gas approaches a theoretical ratio. The amount of the fuel injected is as a function of a changeable feedback correction factor (FAF). When the engine is in a predetermined condition in which the engine controller interrupts the feedback control, a secondary air supplier supplies secondary air from an intake passage to an exhaust passage, and changes the A/F ratio of the exhaust gas. Furthermore, when the engine controller executes the feedback control operation, the secondary air is temporarily supplied to the exhaust passage, for the purpose of diagnosis of the supplier. The diagnostic system detects a first feedback correction factor before the secondary air is supplied, and a second feedback correction factor after the secondary air has been supplied, and calculates a deviation value therebetween.

When the engine is in a predetermined operating condition, the system effects changeover from the first air-fuel ratio control to a second air-fuel ratio control which is responsive to the output from the downstream O.sub.2 sensor for controlling the air-fuel ratio of the mixture by means of the air-fuel ratio correction value.

Abstract: A process is disclosed for the purification of natural gas in which the reduction of the nitrogen content of a natural gas stream is achieved by a combination of absorption, purification, flashing, and reflux steps. More specifically, the process achieves the rejection of inert components such as nitrogen from natural gas without operating in the cryogenic temperature range. The process uses a lean solvent to absorb the non-rejected components in a recovery zone of an absorber and uses a portion of the off-gas from the flashing zone to purify the rich solvent in a purification zone of the absorber. In a further embodiment, solvent entrained in off-gases from low and medium pressure flash zones is recovered in a high pressure flash zone by washing the off-gases with recovered lean solvent.

Abstract: A fabric washing machine includes a container to receive fabrics and washing fluid. An SRM is operatively connected to oscillate and rotate the container. Ribs formed on the center post of the container agitate the fabrics and fluid as the container is oscillated. Just prior to a spin extraction operation the container is oscillated with an asymmetric pattern that travels further in one direction than in the other. To minimize wrapping of the fabrics about the center post the asymmetric pattern is periodically reversed. Also, just prior to the spin operation the motor is operated at a constant torque and the time to accelerate the container from one speed to a higher speed is measured one or more times. The inertia of the load, and thus the size of the fabric load, is calculated from the time measurements. The motor then is operated at a constant torque to accelerate the container from a threshold speed for a predetermined period of time and the final speed of the container is measured.

Abstract: When an upper limit float switch Fu is closed after a lower limit float switch Fl is closed according to a rise of the level of water in a water tank 60, a solenoid water valve WV is closed and power supply to an electric motor for driving an auger 40 and a compressor connected to an evaporator 30 is then allowed. When the lower limit float switch Fl is opened, the solenoid water valve WV is opened and power supply to the electric motor and compressor is cut off. When the lower limit float switch Fl is opened, a time set longer by a predetermined time than the time for the water level in the water tank 60 to reach the upper limit from the lower limit is measured. When the lower limit float switch Fl is kept open due to suspension of water supply, the solenoid water valve WV is closed in response to the completion of measurement of the time. This can suppress power consumption of the solenoid water valve WV.

Abstract: Long products are hot rolled and sized by being subjected to progressively diminishing area reductions in a succession of at least three mechanically interconnected two roll passes driven by a common mill drive. The area reductions are achieved by imparting a first cross sectional configuration to the products rolled in the first roll pass, and by imparting a different second cross sectional configuration to the products being rolled in each of the second and third roll passes. A wide range of product sizes is accommodated by selectively adjusting the speeds at which each of the roll passes is driven by the common mill drive in order to vary the drive speed ratios between successive roll passes.
