Abstract: An ink let recording medium of this disclosure has a substrate and at least one or more ink receiving layers on the substrate, in which a first ink receiving layer which is the outermost surface layer contains anionic inorganic particles having an average particle diameter of 3.0 ?m or more, a binder, a cationic polymer, and a polyvalent metal salt, the content of the polyvalent metal salt based on the anionic inorganic particles in the first ink receiving layer is 5 mass % or more and 40 mass % or less, the content ratio of the polyvalent metal salt to the cationic polymer in the first ink receiving layer (Content of polyvalent metal salt/Content of cationic polymer) is 1.0 or more and 8.0 or less, and the arithmetic average roughness Ra of the surface of the recording medium is 1.0 ?m or more.

Abstract: Embodiments provide treated print media, treatment compositions, and methods for forming treated print media. In some embodiments, a treated print medium may include a substrate and a treatment layer on the substrate, the treatment layer including microfibrils and an ink-fixing agent. Other embodiments are described and claimed.

Abstract: The invention is directed to a method for preparing a polymer derived from an animal protein, such as in a feedstock derived from animal by-products. The method involves hydrolyzing proteins present in a feedstock to obtain hydrolyzed proteins, wherein hydrolysis is conducted under conditions sufficient to digest the proteins and destroy pathogens; extracting a protein fraction from the hydrolyzed proteins; and treating the protein fraction with a crosslinking reagent to form the polymer. The crosslinking reagents may include epoxies. The polymer may be further processed to form a thermoset plastic. The polymer may be used as an adhesive, or in the preparation of a natural fiber composite material.

Abstract: A printing portion of a time recorder having belt printing types comprises a plurality of hour-use belt printing types arranged in a row on a surface of a first belt and gradually fed by hour unit in accordance with a time signal, a plurality of minute-use belt printing types arranged in a row on a surface of a second belt and gradually fed by minute unit in accordance with a time signal, and urging and rotating means for urging printing typefaces of the printing types arranged on the first and second belts against a printing surface of a time card inserted into the time recorder and rotating the same in order to effect a printing on the printing surface of the time card.

Abstract: An apparatus for registering cards for printing in time recorders and the like uses a punch and die to form perforations which are co-linear with the printed information on the card. The perforations are sensed on subsequent insertions of the card and are used to prevent further insertion of the card and register the card in position so that each printing on the card will be made below previous printings.
