Abstract: A lashing assembly lashes together two or more fiber optic telecommunications cables. The lashing assembly comprises at least a first and a second bobbin. As the cables are passed through the first bobbin, twine pays off from the first bobbin and wraps around the cables in a clockwise helix. As the cables are passed through the second bobbin, twine pays off from the second bobbin and wraps around the cables in a counterclockwise helix. In this way, the twine from the first and second bobbins lash the cables together as the cables are passed through the first and second bobbins.

Abstract: A method and device for adjusting the unstored length of tubing directed to improving the use of infusion sets that deliver fluids to a user. The device includes a storage module and other features for adjusting, storing and securing the length of the tubing. The method of adjusting the length of the tubing to a desired length typically comprises removably attaching the tubing to the adjuster, adjusting the tubing by wrapping the tubing around a hub or post of the adjuster, and fixing the length of the unstored tubing by attaching the tubing to a securing device such as a friction structure or fastener.

Abstract: The present invention relates to a traverse guide of a novel design and construction and a transfer link that together transfer the advancing yarn to a grasping device and, once it has been grasped, back to the traverse guide. The transfer link shifts the advancing yarn from the traverse guide while still positioning the yarn within a virtual controlled zone within which the yarn stays until it is grasped by the grasping device, where after, during the return stroke of transfer link, the advancing yarn is placed back into the traverse guide so that yarn can be uniformly wound on the bobbin.

The supporting surface, on which the bobbin tube is disposed on the nipping ring, is so designed that a relative motion between the bobbin plate and bobbin tube is prevented.

Abstract: According to the invention there is provided a cord rewinder which includes two sets of multiple pulleys, each set being seated at an opposite end of an elongate housing. One set is fixed in place while the other set is biased toward its corresponding end of the housing. When a pull is applied to a cord helically wound around the pulleys and extending along the length of the housing between the pulleys, the biased pulley set moves toward the fixed pulley set releasing the cord. When the pull is removed, the biased pulley set moves back to its end position retracting the cord.

Abstract: A device for retracting and storing a length of hose is provided. The device is housed within a dental cabinet and includes a rectangular compartment formed by integral side walls and front and rear walls. A plurality of spool supports are positioned adjacent to the side walls. A spool is positionable within the compartment. A length of hose anchored at the rear wall is routed under the spool and through an opening in an instrument panel of the dental cabinet. At the distal end of the hose is attached the desired dental tool. In retracted position, the hose hangs in a loop or bight with the spool supported on the bight. The weight of the spool normally keeps the hose under tension. The device is operated by pulling on the distal end of the hose such that the spool is lifted onto and secured by the spool supports. In this position, tension is released from the hose.

Abstract: An above-ground gravity return hose retractor, which is particularly useful in service stations for supplying air and water, encloses the hoses and the retraction mechanism within a cabinet. A block and tackle pulley arrangement, including a vertically movable pulley sheave supported by the hose, is located within the cabinet. The movable pulley sheave has a non-linear, variable weight attached to it in the form of an elongated chain having a first segment of small, relatively lightweight links attached through a limit spring to the sheave. These lightweight links then are attached to an additional segment of chain having intermediate weight links, with the lowermost portion of the chain comprising larger, heavier links. The final link in the chain is attached to the bottom of the cabinet. The full length of the chain is reached just prior to the final extension of the hose. The limit spring then provides a significant increase in resistance to further withdrawal of the hose when the chain is fully extended.
