摘要:
Coating compositions comprising a pigment and starch dispersion of discrete crosslinked starch particles in an aqueous liquid. The dispersion may be used as coating color for paper. A preferred process of preparing the dispersion of starch particles comprises (a) obtaining a mixture of starch and an aqueous liquid; (b) processing the mixture using shear forces in the presence of a crosslinker in an extruder; and (c) injecting a hydroxylic liquid into the extruder and dispersing the mixture inside the extruder or outside the extruder or both inside and outside the extruder to obtain the dispersion.
摘要:
A system and method for transferring digital data via the sub-carrier of a commercial broadcast FM radio station. Digital data generated by an originating subscriber is shaped with substantially a raised cosine response in the time domain. The shaped signal is then pre-emphasized and used to frequency modulate (direct angle modulate) a sub-carrier. The sub-carrier in turn frequency modulates the carrier and the data is transmitted by the radio station along with its commercial program. A receiving subscriber detects the sub-carrier and decodes and displays the originated data.

A system and method for identifying and controlling the movement of various items, e.g., suitcases, associated with respective ones of various individuals, e.g., those desiring to travel on a selected means of transportation such as an airline, railway or the like. The system includes a plurality of programmable fingerprint readers each associated with a respective one of the items, a fingerprint scanner for scanning fingerprints from each individual and associating it with one or more of the items, a CPU for receiving readings from each of the item fingerprint readers and information from the scanner, and a retrieving unit (e.g., such as one owned by the transporting party) which retrieves selected ones of the fingerprint readings stored by the CPU for comparing with also retrieved readings from the respective fingerprint readers when the traveling individual presents an item to the transporting party for travel.
