  • Patent number: 6030673
    Abstract: Compositions, methods, and systems for manufacturing articles, particularly containers and packaging materials, having a particle packed, highly inorganically filled, cellular matrix are disclosed. Suitable inorganically filled mixtures are prepared by mixing together a starch-based binder, a solvent, inorganic aggregates, and optimal admixtures, e.g., fibers, mold-releasing agents, rheology-modifying agents, plasticizers, coating materials, and dispersants, in the correct proportions to form an article which has the desired performance criteria. The inorganically filled mixtures have a predetermined viscosity and are heated between molds at an elevated temperature and pressure to produce form-stable articles having a desired shape and a selectively controlled cellular, structure matrix. The molded articles may be placed in a high humidity chamber to obtain the necessary flexibility for their intended use.

  • Patent number: 6030467
    Abstract: The present invention relates to a surfactant solution, and to using an aqueous solution of the surfactants, optionally with an antifoaming additive, for removing or washing MFAC contaminants from equipment, sludge, scale, and soil, among others. Examples of MFAC and related contaminants that can be removed by practicing the invention include at least a member of the tetraalkylleads, including but not limited too, tetramethyllead, trimethylethyllead, dimethyldiethyllead, methyltriethyllead, and tetraethyllead. While any suitable surfactant can be used for practicing the invention, an aqueous solution containing at least one member from the group of nonionic alcohol ethoxylates, including but not limited to the polyethoxylated aliphatic alcohols, is particularly effective at removing MFAC contaminants.

  • Patent number: 6026746
    Abstract: In offset presses in which the printing cylinder is provided with a tensioning spindle or reel rod the printing plate usually has a hooked edge which is inserted in a gap in the printing cylinder. The printing plate is then wrapped around the plate cylinder for insertion in the spindle within the plate cylinder. The tensioning spindle carries a slot for receiving an end of the printing plate. After insertion of the plate end in this receiving slot partial rotation of the spindle tightens the printing plate. A substantial amount of skill is required to fix a printing plate on a printing cylinder. It is not easy to align the gap in the printing cylinder with the slot in the tensioning spindle. Two hands are usually required. Herein the tensioning spindle end shaft carries a pinion capable of moving a rack associated with it when the tensioning spindle is partially rotated. A spring is installed to oppose the rack movement.
