Abstract: A circuit is described which makes use of a mathematical transformation based solely on AND and OR connections for the purpose of recognizing patterns, and a process for localizing this pattern within a zone or range. By means of the direct connection of AND and OR gates, a completely parallel processing of each individual bit is achieved in the arithmetic and logic unit so implemented, which signifies a fraction of the processing time as compared to full adders. Simultaneously the equipment is capable of recognizing a specific pattern (object) from a multitude of mutually nested structures (neighborhood) and to localize it by a subsequent procedure.

Abstract: A cable drum arrangement including a brake drum on a stationary support and a brake shoe on a carrier for the cable drum includes a flyweight and a compression spring radially interposed between flyweight and brake shoe which biases the brake shoe toward the brake drum by centrifugal force generated by the fly-weight while a cable unwinds from the drum. Unwinding of the last layer of cable from the cable drum releases a coupling connecting the drum to the carrier, and the resulting, limited, angular displacement of carrier and cable drum causes a cam to stress the spring and thereby to arrest the carrier. During unwinding, the spring reduces braking stress in the cable by damping radial movement of the flyweight during sudden increases in rotary speed.
