Abstract: VOICE SYNTHESIZER                 ABSTRACT OF THE DISCLOSURE       A voice synthesizer that is responsive to sequences of digital input command words to phonetically synthesize human speech. The system includes control circuits that are responsive to the input command words to introduce an articulated silent pho-neme into the speech pattern, vary the duration of each phoneme produced, as well as to vary the overall sate and volume of the speech generated. In addition, the design utilizes inflection assign-ment for individual phonemes and also employs a glottal waveform which is more representative of human glottis action. The inven-tion also incorporates resonant suppression into the vocal tract to simulate the dampening effect due to the opening of the glottis, and provides closer simulation of human energy content at higher fre-quencies to improve the quality of the speech generated.

Abstract: BACON ANALOG PROCESS ABSTRACT OF THE DISCLOSURE Disclosed is an improved bacon analog and a process for preparing it. The bacon analog comprises: (1) a fat phase based on a heat coagulable component selected from the group consisting of egg albumen, blood albumin and combinations of these, a water-soluble, film-forming component such as gelatin, and a fat compo-nent; and (2) a lean phase based on a loose oil-in-water disper-sion of a heat coagulable protein component such as egg albumen and a fat component which comprises a blend of palm oil with a partially hydrogenated soy bean oil. The lean phase, due to the oil blend, the loose dispersion and deaeration, when used with the particular fat phase formulation, has a chewy texture much like natural bacon. Moreover, the product responds to frying by browning and crinkling much like natural bacon. The novel pro-cess calls for deaerating the lean phase, and dry blending the gelatin with the other fat phase dry components prior to adding water in preparing the fat phase.

Abstract: ABSTRACT OF THE DISCLOSURE          An electric cribbage board is described wherein the score for each player is shown by the illumination of a respective one of a number of lightable indicator devices forming a respective "track" or "street".  The board is arranged to illuminate two successive devices in each track, the leading device indicating the total game score, while the trailing device indicates the just preceding total score.          Facilities are provided for displaying and therefore checking a hand count before it is added to the respective total score count for each player so as to light the appropriate indicator.          The board avoids the need for mental computation as is required with completely manual cribbage boards, or known electro-mechanical cribbage boards, and thereby assists in eliminating incorrect hand and total score counts during playing of the card game of cribbage.

Abstract: Abstract A method and apparatus is disclosed for effecting ac-celerated chemical reactions between reactants at elevated tem-peratures and pressures including the wet oxidation of mate-rials in waste streams.  A reactor has a through pipe that ex-tends down into a cased hole in the earth and back up, the hole providing a subterranean housing for but separate from said re-actor.  Apparatus pumps a controlled flow of influent fl~id with reactants down the pipe at a selected pressure and flow rate for enhancing the reaction to form a hydrostatic column of fluid that is of sufficient depth to exert a pressure and provide a temperature sufficient to cause reactants to react at an accel-erated reaction rate and to achieve the necessary retention time to substantinlly complete the reaction.  Heat is released in the reaction zone to heat the fluid.  Apparatus controls the temper-ature of the fluid in the reaction zone by adding heat for start-up and selectively adding or removing heat to maximize the reaction rate and to prevent boiling of the fluid.  When a gas is used as a reactant, apparatus forms enlarged gas bubbles at approximately the ground surface level that are pumped down with the influent fluid to cause intense mixing, contacting, and a chemical reaction in the reaction zone to maximize reaction rates and minimize power requirements for pumping.
