    摘要: High molecular weight, colorless polyesters suitable for shaping into filaments and films are obtained using novel catalysts selected from the group consisting of reaction products of specified antimony or zirconium (IV) compounds with (1) a carboxylate of calcium, manganese or zinc and (2) an acid anhydride, alcohol or glycol. The molar ratio of the antimony or zirconium compound to the aforementioned carboxylate is between 1:1 and 1:6. The catalysts are active in both transesterification and polycondensation. The rates of these reactions are more rapid than can be achieved using prior art catalysts.

    摘要: An intrusion-free optical cable of the type wherein one or more signal-carrying optical fibers are carried within an outer cladding which will self-destruct, with or without destruction of the inner signal-carrying fiber, in the event an attempt is made to penetrate the outer cladding and extract a signal. Self-destruction is sensed to indicate that an attempt has been made to penetrate the outer cladding. Various embodiments of the invention are shown including a cladding formed from tempered glass which will shatter when an attempt is made to penetrate it. In another embodiment, a laser is employed which directs a light beam through the cable. This light beam is of sufficient power to melt, or at least raise the temperature of, the cladding or fiber at a point where penetration is attempted such that the severance or rise in temperature can be detected.
