Title: Decoding device capable of forwardly and backwardly reproducing pictures with a high quality
Inventor: OHTA MUTSUMI
IPC: H04N19/44
Filed: 1990-05-14
Granted: 1993-09-07
Abstract: Abstract of the Disclosure:         In a decoding device for decoding an input signal into a decoded signal, a delay circuit delays the decoded signal into a delayed signal with a delay equal to a frame period of a digital video signal which is encoded into an encoded signal by interframe predictive encoding.  A forward filter of a predetermined filtering characteristic filters the delayed signal into a first filtered signal.  An adder adds the input signal to the first filtered signal to produce an added signal.  A subtracter subtracts the input signal from the delayed signal to produce a subtracted signal.  An inverse filter filters the subtracted signal into a second filtered signal.  Responsive to a mode signal, a selector selects one of the added and the second filtered signals to produce, as the decoded signal, the added and the second filtered signals when the mode signal indicates that the input signal is produced in a forward direction from a leading part to a trailing part of the encoded signal and when the mode signal indicates that the input signal is produced in a backward direction reversed relative to the forward direction, respectively.  Another inverse filter may be inserted between the delaying circuit and the subtracter.  In this case, the subtracter and the second filter are replaced in position with each other.

Title: Municipal waste thermal oxidation system
Inventor: POPE G MICHAEL
IPC: F23G5/16
Filed: 1990-10-30
Granted: 1995-04-11
Abstract: An air-starved, batch burn, modular, municipal waste incinerator. It is designed to oxidize unsorted loads of heterogeneous materials in quantities ranging from 5 to 500 tons per 12 to 15 hours. The unique aspect of this system design is that through research in air mixing, air turbulence, and temperature control, it is possible to burn this material with a highly favorable stack emission product, without the need for bag houses, dry scrubbing, or other elaborate down stream air processing equipment. The incinerator includes a primary combustion chamber connected to a secondary combustion unit by a gas transfer tube. Solid material in the primary is oxidized - or gasified - without live flame. This flammable gas stream is vented into the secondary for ignition. Combustion gases from the primary chamber are completely burned in the secondary combustion unit as the gases pass upwardly through the air mixing ring and tangentially disposed re-ignition burners. The tangential orientation of the re-ignition burners forms a vortex of flame through which the combustion gases travel before exiting from the stack.

Title: Cone shaped flocculation tank
Inventor: KALLIS LYLE GRANT
IPC: B01D21/08
Filed: 1993-07-02
Granted: 2000-06-13
Abstract: When drilling wells a drill fluid is used to lubricate the drill bit and remove the drilled out material from the bottom of the drill hole. In this invention a partly cylindrical and partly conical vertical tank, capable of being moved from site to site, permits the contaminated drill fluid to be cleaned for re-use in the drilling operation, thereby permitting less drill fluid to be used in each drilling operation. The contaminated drill fluid is introduced into the tank at its middle, through an input centrifuge pipe which enlarges and circles the inside of the tank. The centrifuge pipe has slots along its bottom. As the contaminated drill fluid is pumped into the tank the drilled out material settles out and the clear fluid rises to the top of the tank, is retrieved through the output pipe and re-used. The intake of the output pipe is directed upwards and flanged outwards to form a bowl like effect.

Abstract: Un filtre à onde acoustique de surface (SAW), ou d'autres filtres d'amplificateur FI groupés, est suivi d'une chaîne d'amplificateurs FI et d'un second détecteur ménagés dans les limites d'un circuit intégré monolithique. La chaîne d'amplificateurs FI comprend trois amplificateurs différentiels, couplés à un émetteur, dont chacun présente un gain de tension pouvant être multiplé par vingt environ, et montés en cascade l'un après l'autre. Il est possible de commander automatiquement le gain de tension des deux premiers amplificateurs différentiels couplés à un émetteur. Des amplificateurs à collecteur commun sont utilisés pour tamponner l'application des signaux de sortie équilibrés provenant de chacun des amplificateurs différentiels couplés à un émetteur à l'amplificateur différentiel successif ou un second détecteur (DET). Des réponses de courant équilibrées aux potentiels à polarisation directe sur lesquels les signaux équilibrés fournis au second détecteur sont respectivement superposés sont extraites par un filtrage passe-bas (LPF) sur-puce et n'utilisant pas de condensateurs de dérivation FI hors puce. Ces réponses de courant équilibrées sont réalimentées aux émetteurs des transistors dans les amplificateurs (Q68, Q69) à collecteur commun utilisés pour coupler le premier amplificateur différentiel couplé à un émetteur et à régulation de gain dans la chaîne d'amplificateurs FI, au second amplificateur différentiel à régulation de gain dans la chaîne d'amplificateurs FI. Ceci complète une boucle de réaction à couplage direct afin de réduire les différences entre les potentiels de polarisation directe sur lesquels les signaux équilibrés fournis au second détecteur sont respectivement superposés.
