摘要： A tensile testing system for use with a specimen of rubber or other material having a test region defined on its reduced midportion by a marking or markings of, for example, higher lightness than the other specimen surface. The system comprises a scanning device for repeatedly translating the optical characteristics of the specimen or specimens into an electrical signal as the specimen or specimens are subjected to increasing tensile stress, and a gate circuit for deriving from the output signal of the scanning device its portions corresponding to the test region or regions. The varying length of the test region or regions can be represented either by pulse durations or by pulse numbers. The scanning device can be either an "area scanner" such as a television camera or a "line scanner" such as a solid-state line image sensor. Various embodiments are disclosed.

摘要： A tension tester in which a specimen marked with at least one measuring marking whose optical characteristic is different from that of the specimen's ground color is held by chucks at the ends and subjected to a tensile load by moving one of the chucks; in which, while the specimen is being stretched, the marking is scanned by a scanner to detect a positional change of the marking in the tensile direction; and in which electric signals which are produced due to the difference in the optical characteristic between the marking and the specimen's ground color are processed to determine the tensile characteristic of the specimen. In this tension tester, the scanner consists of a first scanner with its field of view set to the entire elongation range of the specimen; and at least one second scanner having its field of view set only to a low elongation range of the specimen, the second scanner either having a greater number of elements than the first scanner or being adapted to perform a magnified scanning with greater magnification than that of the first scanner.

摘要： A method of measuring or controlling ozone concentration by ultraviolet ray absorptiometry, includes charging air into a testing tank with its temperature controlled, measuring the disturbing gases generated from testpieces such as rubber samples inside the testing tank by regarding them as ozone, subtracting a value representative of the disturbing gases with a calculation circuit from a value indicative of the preexisting state in the tank to set the ozone concentration at zero, generating a necessary quantity of ozone with an ozonizer by using the zero ozone concentration as a reference point, suspending the generation of ozone after the passage of a predetermined time, measuring once again to obtain a new ozone concentration zero value, adjusting the ozone concentration zero value to the new value if there has been a change in the amount of disturbing gases generated, and repeating at least once the operation described above to regulate the ozone concentration to a desired ozone concentration.
