Devices and methods for tension measurements and applications of same

A device for measuring a tension of a bio-object construct as it is being stretched that includes a microscope, a holding member for accommodating the bio-object, and a probe. The microscope includes a condenser, an objective and a stage positioned therebetween. The stage is movable along a horizontal plane. The holding member is fixable on the stage. The probe has a first end attached to the condenser, and a second end placed in the holding member. The stage operably moves such that the bio-object construct moves toward the second end of the probe and contacts with the second end of the probe, thereby causing a displacement of the second end of the probe and a displacement of the bio-object construct, which are used to measure the tension of the bio-object construct.

THREAD GUIDE WEAR TESTING MACHINE AND THREAD GUIDE WEAR TESTING METHOD

A thread guide wear testing machine wears a test piece by causing a thread to slide while the thread contacts the test piece. The thread guide wear testing machine includes a winding reel winding the thread thereon fed from thread feeder. A winding drum guides the thread fed from the thread feeder to the winding reel. The winding drum has an outer peripheral surface contacting an outer peripheral surface of the winding reel. Specimen holder is on a path of the thread fed from the thread feeder and moves while being wound on the winding reel. The specimen holder holds the test piece in contact with the thread under a predetermined load. Tension adjuster adjusts tension on the thread when the test piece is in contact. Contact retainer retains a state of contact between the winding reel and the winding drum by pressing the winding reel toward the winding drum.

The present disclosure relates to a device which automatically clears high elongation test samples with long tails after breakage from a materials testing device after the testing has been performed. A robotic arm engages the tested specimen and brings it to a specimen clearing device which includes a slot leading to a nip between an opposed drive wheel and driven wheel. A motor drives the drive wheel to move the tested specimen through the specimen clearing device into a scrap bin or similar repository.

Termination installation for long cables
10656033 · 2020-05-19 · ·

A method for creating a composite cable having at least one high-performance termination on at least one end. A high-performance termination is added to an end of a short synthetic tensile strength member. The strength of the tensile strength member and termination is then tested. Once tested satisfactorily, the short cable is spiced onto a long cable of the same type using prior art splicing techniques. The union of the short cable and the long cable creates a composite cable having a high-performance termination on at least one end. In most applications it is preferable to set the length of the short cable so that the interwoven splice will exist at a desired location.

SELF-HEALING METHOD FOR FRACTURED SiC AMORPHOUS NANOWIRES
20200018670 · 2020-01-16 ·

The present invention provides a self-healing method for fractured SiC amorphous nanowires. A goat hair in a Chinese brush pen of goat hair moves and transfers single crystal nanowires under an optical microscope. On an in-situ nanomechanical test system of a TEM, local single crystal nanowires are irradiated with an electron beam for conducting amorphization transformation. Amorphous length of a single crystal after transformation is 60-100 nm. A fracture strength test is conducted on the amorphous nanowires in the single crystal after transformation in the TEM; and fracture strength of the amorphous nanowires is 9-11 GPa. After the amorphous nanowires are fractured, unloading causes a slight contact between the fractured end surfaces; and self-healing of the nanowires is conducted after waiting for 16-25 min in a vacuum chamber of the TEM. Atom diffusion is found at a healed fracture through in-situ TEM representation; and recrystallization is found in the amorphous nanowires. The present invention provides a method for realizing self-healing for fractured SiC amorphous nanowires without external intervention.
