A process is disclosed for converting a bis-(diol) terephthalate to dimethyl terephthalate, by interchange in a methanol medium in the presence of magnesium methylate as catalyst. In this way dimethyl terephthalate may be regenerated from scrap of polyterephthalate or copolyterephthalate filaments or films, for the purpose of manufacturing fresh polyterephthalates or copolyterephthalates which can...

PURPOSE:To improve the detecting efficiency of defects by executing all instructions than a branch instruction forcedly in the order of addresses in a program stored in a read-only memory (ROM). CONSTITUTION:A branch instruction control circuit 4 is formed to save the succeeding address of a branch instruction of a program counter 2 in a stack memory 3 at the execution of the branch instruction su...

A light transmitting panel composed of at least two panes held in spaced relation by a spacer assembly to define at least one space between panes is given improved sound damping properties by employing panes which exhibit at least two different masses per unit surface area, by causing the space between panes to be sealed from the external atmosphere, and by filling this space with a gaseous medium...
