Title: Speech synchronized animation
Inventor: GASPER ELON
IPC: G06T13/00
Filed: 1987-11-24
Granted: 1991-04-16
Abstract: ABSTRACT      A system for providing randomly-accessible animated objects having synchronous audio and visual features suitable for use as an education system or video entertainment system is provided.  The speech sounds and the associated visual and behavioral characteristics of language are broken into their constituent parts to produce encoded communication patterns and characteristics associated with speech.  In response to coded input signals representing speech sounds or combinations of s peechsounds forming words, a coded model is constructed including a voice and animated visual image having synchronized audio and associated visual characteristics to speak the sound or words which were input. A user is presented with a viewing screen having several rows of what are perceived to be domino-like tiles each inscribed with one or more letters.  An animated character including a talking head is also displayed on the screen.  The user selects tiles with a mouse or other input device and moves the tiles about the screen to form words or other combinations of letters.  As a tile is selected, the animated character pronounces the name and sound of the letter inscribed on the tile.  When words are formed, the animated character pronounces the words or the sound of the character combinations formed.

Title: Method of reducing no_ emissions from a stationary combustion turbine
Inventor: PILLSBURY PAUL W
IPC: F23R3/40
Filed: 1988-03-17
Granted: 1991-08-27
Abstract: ABSTRACT OF THE DISCLOSURE           Hydrocarbon fuel is combusted in a combustion turbine by a method which produces NOX emmissions below an ultra-low standard. In the method, first, a mix of hydrocarbon fuel and air in a primary flow thereof is burned in a primary combustion zone so as to produce a flow of hot gas of a temperature above that required for an efficient catalytic reaction and which contains NOX at levels below a low standard but above the ultra-low standard. Next,  the hot gas is mixed with hydrocarbon fuel  in  a  secondary  flow  thereof  in  a  mixing  and vaporization  zone  to  provide  a flow of  heated fuel mixture of a  temperature  above  that required for an efficient  catalytic  reaction.  Thereafter,  the  heated fuel mixture is inefficiently catalytically reacted in a first  catalytic  element  fuel  to  provide  a  flow  of effluent gas of a temperature above that required for an efficient catalytic reaction and which contains NOX at levels below the ultra-low standard and CO and unburned hydrocarbons   (UHC)   at  levels  above  a  acceptable standard. Then, the CO and UHC in the effluent gas flow is mixed in a mixing completion zone to produce a flow of heated mixed effluent gas of a temperature above that required for an efficient catalytic reaction. Finally, the   heated   mixed effluent   gas   is   efficiently catalytically oxidized in a second catalytic element to provide a flow of exhaust gas having emmissions which contains NOX at levels below the ultra-low standard and CO and UHC at levels below the acceptable standard.
