    摘要： A method for cleaving one or more optical fiber(s) at an angle to the optic axis is provided and includes clamping the optical fiber(s) with its coating stripped to expose its distal end. An axial force and/or a bending force is applied to the optical fiber to create internal stresses in the fiber. A sharp blade is provided in an orientation such the blade edge is perpendicular to the optical fiber. The blade is further orientated such that a plane bisecting the blade angle formed between two polished surfaces of the blade is slanted relative to the longitudinal axis of the fiber. The at least one optical fiber is scratched with the sharp blade to create a non-perpendicular cleave having a controlled shape in the region of the scratch. A method of splicing the fibers and a tool for cleaving the fibers are also provided.

    摘要： A method of making steel fibers, preferably for use as a concrete additive, and for the supply thereof in making steel fiber concrete, characterized in that to form the steel fibers (2) first a sheet-metal strip (1) is notched either on one face or both faces so as to form steel-fiber wires (4) that are initially connected together by webs (5), and that further, for subsequently converting the webs (5) into thin easily mutually separable separation webs forming separation surfaces that are fracture-rough and low in burring upon separation, the steel-fiber strip is subjected to a flexing process in which each web (5) is subjected to multiple bending deformations about its longitudinal axis in such a way that incipient cracks are produced at the webs (5) due to fatigue fracture and thus the separation webs are produced.

    摘要： A device and method for cleaving a sample includes: creating an indentation on a top surface of the sample by applying a downward force along a vertical axis, the axis arranging perpendicularly to the top surface of the sample; providing a breaking pin and arranging the breaking pin under the sample to touch the bottom surface of the sample at a position that is directly opposite from the indentation; and, applying a downward force on the sample by providing a left side and right side breaker pin wherein the downward force comprises a left-side downward force extended through the left-side breaker pin and right-side downward force through the right side breaker pin, further the pins that provide the left-side and right-side downward force are disposed on a breaker bar and arranged to be on opposite sides of a vertical axis that extends through the indentation on the top surface.

    摘要： Methods of cutting laminate strengthened glass substrates are disclosed. A method is disclosed which includes providing a laminate strengthened glass substrate having a glass core layer with first and second surface portions, and at least one glass cladding layer fused to the first surface portion or the second surface portion of the glass core layer. The glass core layer has a core coefficient of thermal expansion that is larger than a cladding coefficient of thermal expansion. The method further includes forming an edge defect on the laminate strengthened glass substrate, heating first and second regions of the laminate strengthened glass substrate on the at least one glass cladding layer. The first and second regions are offset from first and second sides of a desired line of separation, respectively. The method further includes propagating a crack imitated at the edge defect between the first and second regions.

    摘要： Methods and apparatuses for separating sheets of brittle material are disclosed. According to one embodiment, a separation apparatus for separating a sheet of brittle material includes a first separation cam positioned adjacent to a sheet conveyance pathway and a second separation cam positioned opposite from and downstream of the first separation cam. The first and second separation cams may be rotated such that the contact faces of the separation cams periodically extend across a centerline of the conveyance pathway. Rotation of the first and second separation cams may be synchronized such that at least the portion of the contact face of the first separation cam and at least the portion of the contact face of the second separation cam periodically extend across the centerline of the conveyance pathway at a separation time and periodically do not extend across the centerline of the conveyance pathway at a non-separation time.
