  • Publication number: 20190142646
    Abstract: A modifiable bandage system; the modifiable bandage system is a modifiable bandage that includes a malleable material, an attached absorbent material, and a removable backing. The malleable material includes a longitudinal severable indicia that defines a severable-longitudinal area. The malleable material further includes a transverse severable indicia that defines a severable-transverse area. The modifiable bandage system functions such that absorbent material may be extended longitudinally by removal of the severable-transverse area and coupling multiple modifiable bandages. Further, the absorbent material may be extended transversely by removal of the severable-longitudinal area and coupling multiple modifiable bandages. The modifiable bandage system is useful for covering various sizes of wounds.

  • Patent number: 5697836
    Abstract: The method of processing poultry comprises the slitting of a poultry carcass along at least one lateral side from the thoracic inlet to the midline of the abdomen, to permit separating a breast portion of the poultry carcass from the back by hinging along an opposite lateral side from the cut. This opens the carcass for evaluation of bacterial contamination of internal organs. The location of the cut is along a line where few bones need to be severed, and the internal organs are not broken or torn, which is a major cause of contamination in conventional poultry processing methods. The longitudinal cut extends from the neck to the pubis and when the breast portion, including the wing on the lateral side where the cut is made is moved, air sac membranes and fat layers will contain the intestines and form separation planes to separate the breast portion from the liver, spleen, heart and intestines. The processing can be mechanized.
