Abstract: ABSTRACT OF THE DISCLOSURE           This invention is directed to a process for preparing glycidyl derivatives of compounds having at least one aromatic hydroxyl group or aromatic amine group per molecule by reacting at least one compound having at least one aromatic hydroxyl group or aromatic amine group per molecule with an excess of at least one epihalohydrin in the presence of an alkali metal hydroxlde and subsequently recovering the glycidyl derivative product.  The process is characterized by (1) conducting the reaction in the presence of an organic solvent which codistills with water and said epihalohydrin at a boiling point below the boiling point of the lowest boiling compound among the compo-nents in the reaction mixture; (2) conducting the reaction at a temperature and a reduced pressure suffi-cient to provide a distillate with a boiling point of from 45°C to 80°C; (3) employing said alkali metal hydroxide as an aqueous solution and adding said aqueous alkali metal hydroxide in a continuous manner over a period of from 0.5 to 10 hours; (4) continuously remov-ing water by means of codistillation at a rate such that the water content of the reaction mixture is less than 6 percent by weight; and (5) separating the water from the codistillate and returning the solvent and epihalohydrin to the reaction mixture.  The process of this invention maximizes the epihalohydrin yields and produces epoxy resins low in hydrolyzable halide.

Abstract: RASTER SCAN DIGITAL DISPLAY SYSTEM    WITH DIGITAL COMPARATOR MEANS                    Abstract In a bit mapped raster scan digital display system, a number of maps each contain a single component of the display data and are read together to provide sets of bytes, each set representing eight pel defining groups.  A compare system is provided for determining when a pel group in a set of bytes compares with a reference pel defining group.  For the, or each, pair of maps, the compare system compares all bits of the two bytes of data with the associated bit of the reference group to provide outputs when a corresponding bit in each of the bytes compares with the two reference bits.  When more than two maps are employed the compare outputs related to all of the pairs of maps are combined to provide an output signal when a pel group in a byte from the maps compares with the reference bits.  In a modification of the system the comparison can be made between one or more of the maps and the corresponding bit or bits of the compare data.
