  • Publication number: 20170290292
    Abstract: Techniques are disclosed for preventing formation of dags on cattle and other commercially produced animals. The surface of the animal, such as the skin, hide, hair, wool or other covering of the animal, is treated with a low-energy, non-sticking hydrophobic coating. The coating may be made from long-chain hydrocarbons, such as stearates, typically with a terminal metal carboxylate group comprising a variety of low-valence metals, e.g., mono or divalent metals, such as calcium, magnesium, potassium, sodium and zinc. The coating makes it difficult for polar substances, such as water, mud, dirt, waste, soil, manure and feed, collectively termed dag, to adhere to the surface of the animal.

  • Patent number: 8955434
    Abstract: A digital flexography system includes an imaging member with a charge generating layer formed from an array of addressable pixels and a charge transport layer thereon. Ink is delivered to the imaging member using a simple rough donor roll, rather than an anilox roll. Instead of controlling the amount of ink delivered using the anilox roll, the amount of ink is controlled by the pixels on the imaging member.
