Abstract: A release coating composition containing about 50 to about 75 wt. % of an epoxy functional silicone; about 8 to about 25 wt. % of a reactive solvent; about 5 to about 25 wt. % of a reactive diluent; about 6 to about 12 wt. % of a wax-treated silica powder; and, about 2 to about 4 wt. % of a photoinitiator is disclosed. The composition is useful in preparing a low-gloss release coating for use on linerless labels.

Abstract: A pair of compact, energy-efficient, intelligent, wireless transceiver units are designed to replace the cable that interconnects a portable bar-code scanner, keyboard, and display or other host to a portable bar-code printer or the like. When reset, the units exchange linkage packets and thereby exchange addresses. Thereafter, the two units communicate in an error-free fashion with each other, even in the presence of noise and interference, by exchanging addressed packets containing error detection information. Alternate transmission frequencies are selected when transmissions cannot be received at one frequency. The host unit may maintain independent linkages with multiple printers or the like, with a switch on the host unit selecting the desired printer. Power usage is minimized by shutting down transmitters, receivers, serial port drivers, and microprocessors whenever possible, and for extended periods when data is not being transmitted.
