Abstract: Shrimp processing apparatus to peel shrimp along with methods for peeling shrimp are described herein. The shrimp processing apparatus may be provided in systems including one or more processing stations configured to peel individual shrimp, where peeling may involve removal of shell segments on the dorsal surfaces of the shrimp abdomen and/or removal of pleopods/swimmerets on the ventral surfaces of the shrimp abdomen and, optionally, separation of shell segments. The processing systems and methods may, in one or more embodiments, include apparatus for and methods of measuring the shrimp.

Abstract: An arrangement for signalling to supervisory equipment in a repeater in a digital transmission system. A digital data test sequence comprising a plurality of multi-bit words each accompanied by a parity check bit is fed to the transmission systems. Digital supervisory signals modulate the test sequence and periodic parity violations are imposed on the test sequence. A first counter counts the periodic violations imposed on the test sequence and a second like counter counts errors in the test signals returned from the system.
