Abstract: The invention concerns a method of reducing the organoleptic effect of undesirable aldehydic components in a triglyceride or derivative thereof by addition of a reaction product of an amine and an organoleptically acceptable aldehyde. The triglyceride may be a food or food component such as an edible fat or a surface active agent such as a detergent. The reaction product may be incorporated in the perfume or flavour to be added to the triglyceride or derivative thereof without distorting their organoleptic effect.

Abstract: A measuring tank capable of providing accurate measurement of liquid contained therein even when not in an upright position having a rear wall connected to left and right side walls and a front wall connected between said side walls and having a generally concave shape with a sight glass affixed thereto adjacent its closest approach to the rear wall. The volume of the tank to the left and right of a plane passing through the centerline of the sight glass being equal and the volume of the tank to the front and rear of a plane passing through the centerline of the sight glass parallel to the rear wall being equal.

Abstract: An automated eddy current fastener hole inspection apparatus and method for providing an automatic indication of the presence of a crack in structural members. The device automatically advances the probe of an eddy current instrument in a hole in the structural member, induces an eddy current, detects the eddy current signal produced by the eddy current instrument, digitizes the eddy current signal, analyzes the digitized signal for the presence of a characteristic signature corresponding to the effect of a crack in the structural member upon the eddy current signal, and alerts the operator of the presence of a crack or of noise conditions in the eddy current signal which may mask the presence of a crack. The device is responsive to contiguous repetitions of the characteristic signature of a crack within predetermined time windows to distinguish between data corresponding to a bona fide crack in the structural member from data produced by the effect of noise, dirt, grease, etc. upon the eddy current signal.
