  • Publication number: 20170055561
    Abstract: Novel products comprising conditioned cell culture medium compositions and methods of use are described. The conditioned cell medium compositions of the invention may be comprised of any known defined or undefined medium and may be conditioned using any eukaryotic cell type. Once the cell medium of the invention is conditioned, it may be used in any state. Physical embodiments of the conditioned medium include, but are not limited to, liquid or solid, frozen, lyophilized or dried into a powder. Additionally, the medium is formulated with a pharmaceutically acceptable carrier as a vehicle for internal administration, applied directly to a food item or product, or formulated with a salve or ointment for topical applications. Also, the medium may be further processed to concentrate or reduce one or more factors or components contained within the medium.

  • Publication number: 20160368024
    Abstract: A screen bar for a bar screen may comprise a steel composite sheet having at least three steel layers: a top layer, a core layer, and a bottom layer. The top, core, and bottom steel layers may be interconnected by roll cladding in a non-releasable manner. In some examples, the core steel layer may have a higher deformability than the top steel layer and the bottom steel layer. Likewise, the top steel layer and the bottom steel layer may have higher hardnesses than the core steel layer. Such screen bars have extended service life and can be manufactured more cost effectively, amongst other benefits. Methods for manufacturing such screen bars may involve a variety of steps including hot rolling and/or heat-treating.
