  • Publication number: 20210323110
    Abstract: A system for polishing a cylindrical lip-seal surface includes a spin platter, a polisher having an abrasive surface, and a fixture. The spin platter rotates about a rotation axis to spin a workpiece, shaped as a hollow cylinder, about a cylinder axis of the hollow cylinder. The fixture holds the polisher against an outward-facing cylindrical surface of the hollow cylinder to polish the cylindrical surface with the abrasive surface while the workpiece is spun by the spin platter. A method for polishing a cylindrical lip-seal surface includes spinning, with a spin platter, a workpiece shaped as a hollow cylinder about a first cylinder axis of the cylinder. The method also includes holding, during the spinning, a polisher having an abrasive surface against an outward-facing cylindrical surface of the hollow cylinder to polish the cylindrical surface.

  • Patent number: 10624376
    Abstract: A process for preparing an aqueous solution of a methylcellulose having anhydroglucose units joined by 1-4 linkages wherein hydroxy groups of anhydroglucose units are substituted with methyl groups such that s23/s26 is 0.36 or less, wherein s23 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 3-positions of the anhydroglucose unit are substituted with methyl groups and wherein s26 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 6-positions of the anhydroglucose unit are substituted with methyl groups, comprises the step of mixing the methylcellulose with an aqueous liquid at a temperature of not higher than 10° C. at a shear rate of at least 1000 s?1.

  • Patent number: 9763457
    Abstract: A food cutter has a base and at least two transverse panels extending from the base and sized to complement a pan. The panels may form a grid with an upper end located in the base. The grid has a lower end with cutting edges adapted to cut food. The upper end may be concave and the lower end is flat. The base is formed from a smooth rigid material and may be covered in a soft pliable material. The grid may be coated with a food safe, non-stick material.

  • Publication number: 20160021916
    Abstract: The palatability of a non-starch water-soluble polysaccharide (A) can be improved by at least partially coating the non-starch water-soluble polysaccharide (A) with a methylcellulose (B) having anhydroglucose units joined by 1-4 linkages wherein hydroxy groups of anhydroglucose units are substituted with methyl groups such that s23/s26 is 0.36 or less, wherein s23 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 3-positions of the anhydroglucose unit are substituted with methyl groups and wherein s26 is the molar fraction of anhydroglucose units wherein only the two hydroxy groups in the 2- and 6-positions of the anhydroglucose unit are substituted with methyl groups, with the proviso that the non-starch water-soluble polysaccharide (A) is different from said methylcellulose (B).
