Abstract:

A portable workstation for beadcrafting operations is provided. The workstation includes a base including at least one receptacle for holding parts such as beads, preferably in a desired pattern. A cover interfittable with the base includes a seal portion that engages and surrounds the receptacle so as to maintain the parts in their desired position, despite movement of the workstation.

Abstract:

A design board container enabling the arrangement and temporary positional securement of beading elements is provided. The container includes a base member and a lid member preferably in hinged relationship with one another. The base member and lid member include a design liner and lid liner, respectively, formed of a resiliently deformable and preferably compressible material. The liners are preferably substantially planar, i. e. , a flat surface, so as to allow for free form designing unconstrained by preset channels. By closing the container, the lid surface engages the design surface and beading elements such that the beading elements deform the design liner and are positionally secured between the design liner and the lid liner. The surfaces of the lid liner and the design liner preferably comprise gripping members, such as filamentary or hair-like elements.

International Classification:

B42F 1/08

US Classification:

Abstract:

The present invention is directed toward a bead securement device comprising a tension spring, a first cover and a second cover. The first cover and the second cover are removably secured to the tension spring. In use, a force is exerted on the spring through the covers causing the spring to deform and the gaps between the plurality of coils on the spring expand. Once expanded, the filament may be passed in between one of these gaps so that when the force exerted on the end members of the spring is released, the filament is squeezed between the coils of the spring and held in place. The filament can be easily removed by using the covers to manipulate the end members of the spring.

Abstract:

A bead crimping tool for crimping a bead element and method for use, wherein the tool includes a base handle, a crush plate member, a pair of opposed pincer members, an actuator handle, and a crush arm member. The bead element is placed on the crush plate and preferably secured in place by the crush arm. Crimping the bead includes squeezing of the actuator handle. During a first portion of such actuation, a cam portion of the actuator handle cases the pincer members to impart a lateral compressive force to a lateral portion of the bead element sufficient to collapse the bead element in a lateral direction. During a subsequent second portion of the single actuation cycle, the crush arm is caused to impart a longitudinal compressive force about a top portion of the bead element sufficient to compress the collapsed bead element in a longitudinal direction.

Abstract:

An extensometer having a loop of a single-mode optical fiber. At least two points of the loop are attached to desired locations on a specimen. Light is transmitted through the loop and the transmitted optical power is measured by a photodetector. The deformation of the specimen causes the size and shape of the loop to change, which changes the transmitted optical power. The change in optical power is related to extension or compression using calibration curves. The sensor works on the principle of transmitted power modulation through the curved section.
