Abstract: Embodiments of the present invention provide modular grid systems for use with aperture-forming devices. The modular grid system includes a plurality of modular grids, wherein each modular grid includes an outer frame, an outer partial ring coupled to the frame, and at least one inner partial ring coupled to the outer partial ring via at least one securable connection, wherein the outer partial ring and the at least one inner partial ring form arcs of greater than 180 degrees but less than 360 degrees. Each modular grid is coupled to an adjacent modular grid. In some embodiments, the outer frame comprises a removable bar. In some embodiments, the plurality of modular grids are oriented in the same direction. In some embodiments, the modular grid is configured to couple to an aperture-forming device, where the aperture-forming device has a diameter ranging from 2 to 6 inches.

Abstract: This patent application is for devices and methods for forming lifting pockets in concrete structures. In some embodiments, a lifting hook or other lifting device may engage rigid or flexible cables or other structures accessible in the pocket to facilitate movement of the concrete structure.

Abstract: Devices and methods for twisting yarn may twist a strip of material, such as a paper strip, into a yarn, such as a paper yarn. Such devices and methods may involve positioning a pad formed from a roll of the material horizontally in a yarn twisting device, such that the strip of material is unwound and drawn from an outer circumference of the pad, but down through the center of the pad, and subsequently through a rotating yarn twister.

Abstract: A re-pulpable paper tape capable of use in paper pulp bailing applications is disclosed. The paper tape comprises a paper web having a first width, the paper web longitudinally folded to a final width that is less than the first width to form a folded paper tape; the folded paper tape having an outer surface and inside surfaces; and a re-pulpable adhesive applied to the paper web such that the adhesive covers substantially the entire inside surfaces of the folded paper tape, wherein the folded paper tape is strong enough to be used in paper pulp bailing applications. Methods of manufacturing folded paper tape capable of being used in paper pulp bailing applications are disclosed. Systems for bailing paper pulp utilizing folded paper tape are disclosed.

Abstract: Method and apparatus for binding a bundle using an elongate flat strap having a heat sensitive adhesive thereon. The apparatus includes mechanism for driving the strap in a loop around the bundle, a gripper for gripping an end of the strap, mechanism for drawing the strap taut about the bundle, and heated press elements for clamping adjacent overlapping portions of the strap together to reactivate adhesive in the strap to bond the overlapping sections together. A cutter severs remainder portions of the strap.
