Title: Thermal print head control for printing serial bar codes
Inventor: HELMBOLD JAMES E
IPC: G08B5/22
Filed: 1990-01-22
Abstract: A printer for printing serial bar codes on a web of record members with a thermal print head is shown. The thermal print head is driven by a series of pulses having a constant duty cycle for each row of information printed. However, the number of pulses in the series is varied from row to row, in accordance with the status of the current row being printed as a bar row or a space row; with the status of at least one row immediately preceding the current row and at least one row immediately succeeding the current row; and with the number of bar rows previously printed.      By varying the number of pulses applied to the thermal print head and thus the amount of energy applied thereto, discontinuities in the serial bar code and any information, such as a human readable character, printed adjacent thereto are minimized.

Title: Solventless silicon release coating
Inventor: KESSEL CARL R
IPC: C09J7/02
Filed: 1991-02-07
Abstract: ABSTRACT OF THE DISCLOSURE          This invention relates to solventless , curable polyorganosiloxane compositions, and in particular, to solventless, curable polyorganosiloxane compositions that can be used to prepare release coatings.  Solventless silicone compositions generally provide release surfaces that exhibit a sticky or rubbery feel, which is disliked by users of certain types of transfer tapes.  Users of large transfer tapes, e.g., tapes consisting of a layer of a pressure-sensitive adhesive borne on a removable silicone release liner, prefer to place the tape on the desired substrate, then press the tape down firmly with their hand or forearm, remove the silicone release liner, and then press the second substrate in contact with the exposed surface of the tape.  The users desire that the release liner exhibit a slippery feel so that the friction between the liner and their hand or forearm not bring about chafing of the skin. This invention provides curable, solventless, liquid  polyorganosiloxane compositions for providing release coatings that exhibit a slippery feel.  The composition comprises (a) a first polydiorganosiloxane terminated by silyl groups having one reactive group; (b) a second polydiorganosiloxane terminated by silyl groups having one reactive group, the reactive group of (a) being the same or different from the reactive group of (b), said reactive groups of (a) and (b) being reactive with one another to form a covalent bond; (c) a polydiorganosiloxane having three or more reactive groups that are reactive with either the reactive group of (a) or the reactive group of (b) or both to from a covalent bond; and (d) a catalyst for effecting the reaction of the reactive groups of (a), (b) and (c) to form covalent bonds.  When coated an a substrate and cured, the composition provides release liners for pressure-sensitive  adhesive tapes and pressure-sensitive adhesive transfer tapes.
