    摘要: A plastic bag closer slider has a separator normally resting in notches in the tops of slider track strips, when the slider is at a bag-closed stop. As the slider is moved in the bag-opening direction, the separator is cammed downward by ends of the notches to disengage interlocking profile features and open the tag. In another embodiment, notches are omitted. The separator is manufactured with a normally down position but is resiliently biased upward when the bag is closed. As the slider is moved in the bag-opening direction, the pointed end of the separator wedge descends between the strips to open the bag. When the slider is moved in the bag-closing direction, the separator is cammed upward by the drag of the strip tops and the tapering walls of the slider squeeze interlocking profile features together, closing the bag.

    摘要: A method for detecting the presence of antibody to FIV in a biological sample. The method includes the steps of providing a first antigen having a first epitope recognized by the antibody, the first antigen being detectable; contacting the first antigen with the sample under conditions under which the antibody can bind to the first antigen to form an immune complex; and detecting the immune complex. An ELISA test for FIV, using purified FIV antigen, is also described.

    摘要: A slider zipper reclosable fastener wherein the zipper includes fastener strips and closure elements on the fastener strips which are extruede integrally. The closure elements are arranged at particulare angles by extrusion opeining angles in order to increase burst strength. Ridges on the fastener strips and shoulders on the slider hold the slider on the zipper.

    摘要: A method and apparatus for manufacturing recloseable plastic bags with engageable mating profiles where the bags are provided open for the consumer. The profiles are initially provided in the fully engaged condition within an elongate, longitudinally cut tube. The profiles are then periodically fused, tacked, or attached together at the approximate locations where the tube is to be cut into bags. Upon tacking, the profiles are pulled apart by frictionally engaging an area on the outside of the film, near the profiles, and between the tacks. The film is then forced away from the profiles, which at least partially pulls one profile from the other. Thereafter, the tube may be cut and sealed into bags as would otherwise normally occur.
