Abstract: A record (100) may include a disk (102), an embedded electronic authentication tag (104), a cover (106) between the disk and the electronic authentication tag, and one or more record labels (108A, 108B). The disk, electronic authentication tag, and cover have a spindle hole (114) and a common centerline (116). The electronic authentication tag contains a unique identification code pointing to information regarding the record stored as a non-fungible token. This information may be used to verify the authenticity and ownership of the record. A puck used to create the disk may include segments of different colors so that, when the record is pressed the different segments produce a visual pattern unique to that record. A picture may be taken after pressing, recorded, recorded as part of the information in the non-fungible token, and later used to verify the authenticity of the record.

Abstract: A method and apparatus for the bonding of one or more material layers to a display panel which yields a resulting bonded assembly which is transparent and substantially free of optical defects such as entrapped dirt and air bubbles. During the bonding process of the present disclosure, a moving dispensing probe, or needle, dispenses a liquid bonding material into an air gap between the surfaces to be bonded in a manner which continuously touches (wets) each surface simultaneously. By simultaneously wetting each surface, and by dispensing the liquid bonding material in a predetermined pattern between the surfaces, the introduction of entrapped dirt and the formation of air bubbles is prevented as the two mating surfaces are subsequently pressed together and the adhesive is cured.

During the bonding process of the present disclosure, a moving dispensing probe, or needle (200), dispenses a liquid bonding material (110) into an air gap (300) between the surfaces to be bonded in a manner which continuously touches (wets) each surface simultaneously. By simultaneously wetting each surface, and by dispensing the liquid bonding material (110) in a predetermined pattern between the surfaces, the introduction of entrapped dirt and the formation of air bubbles is prevented as the two mating surfaces are subsequently pressed together and the adhesive is cured.

Abstract: The use of Na.sub.2 CrO.sub.4.10 H.sub.2 O as a heat storage medium is disclosed. Various amounts of Na.sub.2 SO.sub.4.10 H.sub.2 O may be included to provide a melting temperature between 19.degree. C. and 31.9.degree. C. A lower melting temperature can be obtained by adding CO(NH.sub.2).sub.2. Paper sludge or waste products from the processing of sugar cane or peat can be added to increase viscosity. Auxiliary liquids such as trichlorethylene and tetrachlorethylene or silicone oils can be added to maintain pumpability of the compositions.

Abstract: A method of electroplating a crack-free hard chromium deposit comprises having present in the electroplating bath a complex halogen-containing compound which disassociates in an aqueous solution while maintaining the bond of a halogen in the complex. A plating voltage is used which periodically superimposes high voltage pulses on the base voltage.
