Abstract: Method and apparatus for enabling ultrasonic inspection of a changing, insufficiently defined or unknown shape (e.g., a variable radius or a noncircular radius caused by the use of soft tooling) at a rate that meets production requirements. The apparatus comprises a linear ultrasonic array (i.e., sensor) incorporated in a toppler, which in turn is slidably supported by an oscillating sensor mechanism carried by a traveling trailer vehicle. As a result of this arrangement, the sensor can undergo a back-and-forth sweeping motion coupled with motion along the spar radius. The sensor is further able to displace radially relative to a sweep pivot axis and rotate (hereinafter “topple”) about a topple pivot axis. In this manner, the orientation of the sensor can adjust to the contour of the inspected surface as the sensor scans.

Abstract: An aircraft fuel contaminant tester has an upper transparent chamber for viewing a first sample of aviation fuel, a lower chamber, a fuel cell drain valve actuating device for loading the upper transparent chamber. A thumb actuated valve halts flow of fuel from the upper chamber into the lower chamber until actuated by the pilot after viewing contaminated fuel in the upper transparent chamber. The larger lower chamber permits several samples of fuel to be repeatedly drained from the fuel tank and examined merely by manually actuating the valve without the undesired discarding of any fuel. When the fuel in the last batch of sampled fuel, viewed in the upper chamber, is free of contaminants, the inspection process ends and the tester is inverted, draining the sampled fuel from both chambers, usually at one time only, to eliminate the repeated discarding of the fuel from the commonly used sampler cup.

Abstract: The invention relates to a method and a device for identifying a damaged bearing (4a, 4b) of a rotating shaft (1). According to the invention: the rotational speed (n) of the shaft (1) is determined; the alternating component (nAC) of the rotational speed (n) is determined, together with a smooth curve (h) of said alternating component (nAC) of the rotational speed (n); the smooth curve (h) is converted into the frequency range and a frequency response (B) of the value of the smooth curve (h) is determined. Said frequency response (B) of the value of the curve is monitored for the passing of a threshold value (G1, G2, G3, G4) and if said threshold value (G1, G2, G3, G4) is exceeded, a damaged bearing (4a, 4b) is identified. The invention thus provides a method and a device for identifying a damaged bearing (4a, 4b) of a rotating shaft (1) of a motor, which do not require a vibration sensor (11) to identify a damaged bearing (4a, 4b) of said shaft (1).

Abstract: An object of the invention is to realize high-accuracy analysis of a flue gas in terms of a trace amount of ammonia so as to control the level of ammonia gas to be added to a flue gas NOx removal apparatus. Since the ammonia gas to be determined is a highly absorbable, the gas component is considerably adsorbed on a surface of the flue gas sampling tube during sampling of flue gas. When a conventional sampling method including heating a gas sampling tube is employed, the amount of sampled gas is reduced through adsorption during gas sampling, failing to obtain concentration values at high accuracy. Thus, a high-accuracy gas sampling method replacing a conventional, heating-based method includes completely washing out, with an absorption liquid therefor serving as a washing liquid, a target ammonia gas deposited on the inner wall of a flue gas sampling tube (2), whereby the gas component is thoroughly collected. Through analysis of the thus-obtained washing liquid, high-accuracy analysis can be attained.
