The torsion detection mechanism is constituted of displacement gauges such as a linear variable differential transformer. The displacement gauges are provided on hydraulic cylinders, and detect amounts of displacement relative to the reference lengths of the hydraulic cylinders, respectively. The controller calculates a relative torsional angle between the first attachment member and the second attachment member based on the detected displacement.

摘要： A container end leak testing device used for testing a container end. The container end having a score line defining an opening in the container end and a pull tab. The pull tab used for creating the opening therein. The leak testing device includes a pressure transducer disposed directly above a top of the container end to be tested. The pressure transducer, under computer control, is able to test for small volumes of air pressure leaks, ie. 0.1 cubic centimeters and less. The leak testing device also includes a tester housing, an upper housing member, a lower housing member and a container end test pocket disposed between the two housing members. The upper housing member includes the pressure transducer mounted thereon and having an air passage communicating with the test pocket. Also, the upper housing member includes two downwardly extending guide pins and an air actuated stop pin for centering the container end inside the test pocket. The lower housing member moves up and down in the lower portion of the tester housing. The lower housing member includes a spring biased base plunger for engaging the bottom of the container end and compressing the top of the container end against a flat annular ring disposed in the bottom of the upper housing member. The lower housing member and base plunger include an air passage therein for introducing test air pressure in and around the bottom and sides of the container end to determine if any air passes through any leaks in the container end and is sensed by the pressure transducer.

摘要： A method for non-destructive determination of a fatigue limit for a component includes two sub-methods which may be performed separately, or in any order. A direct-deformation sub-method includes measuring micro-plastic deformation corresponding to each of a plurality of different known values of stress applied to the component, and identifying a critical value of stress corresponding to a change in the relationship between stress and micro-plastic deformation. An internal-friction damping method includes initiating torsional oscillations in the component, measuring an initial angular amplitude of oscillation, A.sub.0, and a final angular amplitude of oscillation, A.sub.n at the end of the number, n, of oscillations. This process is repeated a number of times and, for each pair of measurements, a corresponding measure of damping is calculated. A critical value of initial angular amplitude corresponding to a change in the relationship between amplitude and damping is then calculated. All testing is preferably performed torsionally, thereby making the method applicable to a wide range of real components of different shapes. Applied stresses are limited to below the yield point of the materials tested and do not affect the properties of the material.

摘要： A test procedure for the testing liquid storage tanks, for leakage, comprises: immersing at least part of test equipment in the liquid in question and fixing the equipment in position with respect to the tank; allowing a quantity of the liquid in question to be admitted to a multiplier tube, until the level of liquid in the multiplier tube equates to that in the tank; isolating the liquid in the multiplier tube from that in the tank for an appropriate test period; introducing a predetermined measure (M) of liquid of the same nature as that in the tank into the test equipment to establish a recordable datum level removing the predetermined measure (M) of liquid from the test equipment; re-connecting the liquid in the multiplier tube with that in the tank; waiting a prescribed period of time; taking the same measure (M) of liquid and re-introducing this measured amount into the test equipment; and observing any fall of the meniscus of that measure from the previous datum level, which fall would indicate leakage from the tank. The invention also includes test equipment (9).
