  • Patent number: 7975528
    Abstract: A method and apparatus for monitoring and determining fuel vapor recovery performance is disclosed. The dispensing of liquid fuel into a tank by a conventional gas pump nozzle naturally displaces a mixture of air and fuel ullage vapor in the tank. These displaced vapors may be recovered at the dispensing point nozzle by a vapor recovery system. A properly functioning vapor recovery system recovers approximately one unit volume of vapor for every unit volume of dispensed liquid fuel. The ratio of recovered vapor to dispensed fuel is termed the A/L ratio, which should ideally be approximately equal to one (1). The A/L ratio, and thus the proper functioning of the vapor recovery system, may be determined by measuring liquid fuel flow and return vapor flow (using a vapor flow sensor) on a nozzle-by-nozzle basis. The disclosed methods and apparatus provide for the determination of A/L ratios for individual nozzles using a reduced number of vapor flow sensors.

  • Patent number: 7975564
    Abstract: A method and apparatus for increasing the size of small particles for a condensation particle counter, in which method a particle containing aerosol flow is divided into a sample flow and a sheath flow. The sheath flow is filtered, saturated with vapor and formed to a vortex flow in a saturator which vortex-flow continues in a condenser. The sample flow is introduced to the center of the vortex flow of the saturated sheath flow in the condenser for causing the vapor in the saturated sheath flow to condense on the particles in the sample flow thus increasing the size of the particles.

  • Patent number: 7971485
    Abstract: A method of testing an elongate wooden element includes injecting an input acoustic signal into the element, detecting a return acoustic signal at a surface of the element, and determining a spectral profile for the return signal. In at least a predetermined range in the spectral profile, each resonance peak is detected whose amplitude exceeds a first predetermined value, and from the resonance peaks so detected the number of higher peaks is determined whose amplitude exceeds 3 dB. For each of said higher peaks a quality factor Q is calculated, a mean quality value Qm is determined, and Qm is then compared with a predetermined value to provide an indication of the presence or absence of external decay of the element. A ratio R of the number of higher peaks to the number of resonance peaks detected, and the statistical spread S of the average Q for the spectral profile, are calculated and compared with a predetermined boundary function Fn(R,S) to determine acceptability or unacceptability of the pole.
