Abstract: In a noise radar a pseudo-random sequence is generated repeatedly and used to phase modulate a transmitted signal. The transmission is interrupted during a number of periods during each pseudo-random sequence which allows returns from targets to be received from the same antenna as is used for transmission during those periods of interruption. Each transmitted pulse, between successive periods of interruption, contains a different selection of successive digits of the code thus increasing the apparent randomness of the transmitted code and making detection more difficult.

Abstract: Disclosed are oral anesthetic pharmaceutical compositions comprising: (a) from about 0.02% to about 25% of a pharmaceutically acceptable acid salt of a .beta.-aminopropiophenone, such as dyclonine HCl; (b) from about 0.02% to about 20% of saccharin; and (c) from about 1% to about 99% of a pharmaceutically acceptable oral carrier. Also provided are methods for providing an anesthetic effect in humans or animals which comprises orally administering to said human or animal a safe and effective amount of these pharmaceutical compositions. Also provided is a novel process for the manufacture of anesthetic lozenges containing a .beta.-aminopropiophenone along with saccharin.
