Abstract: A loom that includes a first elongated beam having upper and lower surfaces; a second elongated beam having upper and lower surfaces parallel to and spaced from the first beam; a first transverse roller having a first longitudinal axis rotatably mounted on and extending between the first and second beams; a second transverse roller having a second longitudinal axis parallel to and spaced from the first transverse roller rotatably mounted on and extending between the first and second beams; each transverse roller having a peripheral surface formed with a plurality of equally sized and spaced annular grooves, each groove lying in a plane perpendicular to the longitudinal axis of its associated roller; and a disk-shaped thumb wheel having a textured peripheral edge surface fixed to each roller with a center aligned with the longitudinal axis of the roller.

Abstract: A construction system includes an elongated connection stem with a central member having a uniform first transverse dimension and opposed integral end members, each having a uniform second transverse dimension greater than the first, each end member having a longitudinal slot extending from a tip end to the central member and an attachment member having a central through bore slightly smaller than the second transverse dimension. A cross section of each end member is similarly shaped to the central through bore and slightly larger than the central through bore and a cross section of the central member is similarly shaped to the central through bore but of smaller size than the central through bore. In one instance, the attachment member is fittingly received on either of the opposed end members and, in another instance, the attachment member is slidably received on the central member.

Abstract: A frame system for object display includes a main frame with a frame face defining an opening for viewing a display object, a peripheral wall projecting away from the frame face and having first and second opposed segments, the segments formed with first and second female locking features, respectively, a receiving surface for the display object and an easel back selectively mountable on the main frame including a support assembly including a planar support panel and opposed male locking features on the peripheral edge interferingly engageable, respectively, with the female locking features on the opposed segments when the easel back is mounted onto the main frame. The support assembly includes a central panel for biasing the display object into engagement with the receiving surface and a web member extending transverse of the planes of the central panel and the support panel and joining the central panel and the support panel.

Abstract: A novel process for molding articles from superplastic metals. The process is characterized by a fast-cycle utilizing a cooling and high-speed reject steps.

Abstract: During injection molding of a plastic key tag or the like having an integral strap appendage with longitudinally spaced apertures formed therein for accommodating a fastener securing the strap in a looped configuration, a weakened weld line extending between the apertures is created. To discourage eventual splitting of the looped strap along this weld line, a relieved section is molded in the strap at a location calculated to reduce the lateral tensile stresses acting on this weld line.
