Abstract: A heddle shaft (1) with heddles (3) that are supported with little play or free of play has at least one heddle support rail (7), which is supported movably for elastically tensing the heddles (3) as a whole, or has at least one movably supported part (55). A spring means (16, 56) serves to exert a tensing force on the heddle head (5) of each heddle (3) for supporting that heddle without play. This makes a high operating speed of a power loom, provided with such a heddle shaft, possible without the heddles digging into the heddle support rails and without producing excessive noise.

Abstract: A bead stringing apparatus that enables the user to quickly restring pre-strung beads, of the type that are on temporary strings, commonly available in bead stores. The connectors on the apparatus pull both ends of the temporary string in a taut position over an open work space. This aligns the pre-strung beads automatically along the temporary string allowing them to be restrung easily by a permanent string or wire. The user can quickly resting rows of the pre-strung beads by putting their wire through the aligned holes and when the wire exits a row of the pre-strung beads the user can add in other loose beads on their wire to go in and between the pre-strung beads. This allows the user to create infinite designs and patterns of beadwork. The open work space around the pre-strung beads provides flexibility and ample room for the newly incorporated loose beads to hang down onto the permanent wire out of the way of the beading process.

Abstract: Two layered beads (B) arranged between two neighboring warps (tx-1) and (tx) are woven by inserting a weft (yx) through center holes (2) of the beads in (B) in a forward direction or in a backward direction and turning the weft (yx), around one of the warps (t). A two layered beaded fabric is obtained by repeating the movements of the weft (yx). A three layered beaded fabric can be obtained in the same manner as the two layered beaded fabric.

Abstract: A collapsible loom, comprising a folding loom, a removable weaving assembly, including a warp beam (26) with its warps, harness shafts (38), a reed (52), and a cloth beam (19) with its cloth, wherein the removable weaving assembly, which is detachable and transferable to another loom, further includes bars (30) confined in a bar cassette (31), transfer bars (37), tying members (32) for treadles (15), and a number of harness shafts (38) actuated by the treadles (15).

Abstract: The beading loom with a removable warp thread cartridge has warp threads mounted in a cartridge that is removably received in a frame of the loom, allowing the user to bead the threads in a conventional manner, but without having to wrap the threads on the loom manually. Once finished with one beading product, the user may then remove the cartridge from the loom and replace the beaded project with a fresh cartridge of warp threads. The frame has an elongated base having an adjustable length along the longitudinal direction.

Abstract: A loom and method of weaving, the loom having a frame and a member rotatably mounted on the frame. The rotatable member including a chin bar and a heddle. The loom is mountable on an operator's shoulders so that the operator may apply a force to the chin bar of the rotatable member, moving the heddle. Also a tandem loom having a frame supporting two rotatable members, for manipulating the two heddles by multiple operators.

Abstract: A woven plastic bag fabric and method for weaving using a frame with a moveable upper bar, at least two continuous ribbons of plastic bag, by winding a first ribbon without cutting around a post in the fourth frame side around a long post in the first frame side, then another post in the fourth frame side and around a short post in the first frame side until all posts in the first and fourth frame side are used. The movable bar is raised to form a space. A second ribbon is tied to either a second or third frame side, and the second ribbon is threaded through the space around a right edge post, the moveable bar is lowered to form a second space, the second ribbon is threaded through the second space and the threading and movement is repeated until all edge posts are used forming the fabric.

Abstract: A novel rod linkage for driving a heddle shaft includes at least one strap (16), which for damping oscillation has a sandwich structure (37) oriented in the longitudinal direction (L) of the strap assembly (16). The sandwich structure includes at least one rigid element (27), extending in the longitudinal direction, which is joined to one end (17) of the strap assembly (16); a second rigid element (31), likewise extending essentially in the longitudinal direction, which is joined to the other end (19); and a two-dimensional damping element (34), again extending in the longitudinal direction, disposed between the first two. The element (34) exclusively effects the mechanical connection of the two parts (16a, 16b) of the strap assembly (16). Preferably, no additional connecting elements, such as rivets, screws, or other rigid connections, between the rigid elements (27, 31) are provided.

Abstract: A bead-weaving system including a multiplicity of beads for spacing apart a multiplicity of warp threads, wherein the beads are pierced by a hole in their diameter and threaded on a weft thread by a needle and positioned between each warp thread, the needle having a body including an end portion having an eye for passage of a weft thread and another end portion including a bead holder extending along the another end portion to hold the beads in selected positions along the another end portion and a point.

Abstract: Disclosed is a method of drilling, desmearing, and additively circuitizing a printed circuit board. The printed circuit board is drilled under conditions which produce glass and polymer smeared vias and through holes. The particulate debris is removed by vapor blasting the drilled printed circuit board. Next the printed circuit board is soaked in a solvent to swell the drill smear on the circuit interplanes of the printed circuit board. This solvent is then removed by entrainment in a gas, and a stream of an aqueous, acidic, oxidizing solution is passed through the printed circuit board holes to remove swollen smear in the thru holes and produce an etchback of conductors. After a water rinse an aqueous reducing solution is passed through the printed circuit board to reduce and remove aqueous acidic oxidizing solution, e.g., residual aqueous acid oxidizing solution. The printed circuit board is rinsed to remove the aqueous reducing solution.

Abstract: The weft yarn picking channel is constructed for use in pneumatic weaving machines. In one embodiment, the picking channel is formed of discrete guide elements of wire construction which are secured on a sley. In another embodiment, the guide elements can be incorporated in a reed via bends in the reed wires.

Abstract: A hand loom of improved and simplified construction in which the course of travel of the warp threads during the weaving operation is similar to conventional looms. However, the loom of the present invention is provided with a beater which is mounted for horizontal reciprocation so that the beater is maintained parallel and square with the warp threads at all times during such reciprocal movement. The beater is mounted directly adjacent the front harness at a point proximate the greatest opening of the shed.The present loom also has a plurality of harnesses of novel construction, with each of the harnesses being actuated by its own individual lifting means. Thus, a lifting lever, having an elongated arm and an upstanding leg, is positioned beneath each harness and is adapted to raise a selected harness when the outer end of the lever arm is depressed by the operator.
