  • Patent number: 4691464
    Abstract: A flexible fabric covering for avian decoys for enhancing the life-like accuracy of the decoy. Markings are illustrated on the exterior of the covering and represent the surface features of a wildfowl. A reflective iridescent panel is attached to the covering at substantially the location of a duck's secondary feathers to mimic the iridescence of the secondary feathers.

  • Patent number: 4303067
    Abstract: A flexible bag for dispensing medical liquid, such as intravenous solutions, to a patient. The bag has an improved additive port for periodically injecting medication or other liquid into the bag through a puncturable, resealable plug. The additive port includes a flexible support tube segment sealed between opposed walls of the bag and a substantially stiffer puncture tube sealed to an outer end of a port tube segment, which substantially stiffer puncture tube is in turn sealed to a tear-off closure. A puncturable, resealable plug is held against an integral puncturable (nonresealable) diaphragm of the puncture tube by the retaining member sealed within the puncture tube. This construction provides more reliable, leak proof sealing between components of an additive port of a medical liquid bag.
