Abstract: Disclosed is a method and apparatus for selectively distributing on a multiple channel television system information previously transmitted and received in the Baudot code. The transmitted information is encoded into a sequence of Baudot characters to include a combination of figure shift and/or letter shift characters which identifies the category or type of information contained in the sequence. Upon receipt, the sequence is decoded to determine the category of information contained therein and then the information is applied to one of a plurality of storage areas in memory, with the particular storage area selected being dependent upon the determination of the information category. After an information sequence has been received, decoded and stored in one of the storage areas, it is then applied to one or more selected channels of the multiple channel television system for display on television receivers tuned to those selected channels.

Abstract: A hearing aid system and method includes apparatus for receiving a spoken speech signal, apparatus coupled to the receiving apparatus for determining at successive intervals in the speech signal the frequency and amplitude of the largest formants, apparatus for determining at successive intervals the fundamental frequency of the speech signal, and apparatus for determining at successive intervals whether or not the speed signal is voiced or unvoiced. Each successively determined formant frequency is divided by a fixed value, greater than 1, and added thereto is another fixed value, to obtain what are called transposed formant frequencies. The fundamental frequency is also divided by a fixed value, greater than 1, to obtain a transposed fundamental frequency.

Abstract: A counter current decantation system for the fluid separation of liquids or solids having different densities or absorptive capacities wherein the material to be separated is placed in an inclined separator having a series of decantation pipes, each of which is connected at the bottom thereof to a pump for pumping a fluid mixture upstream at varying pressures. The separation fluid enters the separator at the bottom with sufficient force to form a mixture with and agitate the material to be separated. Lighter material is caused to rise toward the fluid surface and the heavier material is caused to settle to the separator floor by gravity. The force supplied is sufficient to cause the fluid mixture to pass forwardly through the length of the separator and thus the fluid mixture has a tendency to flow downstream toward the bottom end of the separator.
