  • Patent number: 11946160
    Abstract: An apparatus and method is provided for coating a surface of a material with a film of porous coordination polymer. A first substrate having a first surface to be coated is positioned in a processing chamber such that the first surface is placed in a substantially opposing relationship to a second surface. In some embodiments, the second surface is provided by a wall of the processing chamber, and in other embodiments the second surface is provided by a second substrate to be coated. The first substrate is held such that a gap exists between the first and second surfaces, and the gap is filled with at least one reaction mixture comprising reagents sufficient to form the crystalline film on at least the first surface. A thin gap (e.g., having a thickness less than 2 mm) between the first and second surfaces is effective for producing a high quality film having a thickness less than 100 ?m.

  • Patent number: 5122128
    Abstract: There is disclosed an insert for the orifice of a ruminal bolus. The insert fits within the exit orifice of the ruminal bolus such that the medicated paste being discharged passes through the insert creating a back pressure within the paste compartment of the bolus which improves the performance of the bolus. The insert also prevents foreign objects from becoming lodged in the orifice. The insert consists of a grid-like series of openings with insert members extending into the orifice for a significant portion of the total length. Integral with the insert is a flange which secures the insert within the orifice and prevents it from being removed from the orifice or from being driven into the orifice.
