Title: Artificial kidney
Inventor: CHEVALLET JACQUES
IPC: A61M1/34
Filed: 1992-09-09
Abstract: An artificial kidney comprises an exchanger (1) having two compartments (2, 3) separated by a semipermeable membrane (4), a first compartment (2) being connected to a circuit (5, 7) for extracorporeal blood circulation, the second compartment (3) having an outlet for draining waste liquid. Means (22, 25) are provided for controlling the flow rate (Q A) of a sterile solution containing a substance (A) to be perfused into the circuit (5, 7) for conveying a flow of blood outside the body, which flow rate is controlled as a function of the flow rate (Q OUT) of waste liquid.

Title: Particulate filtration apparatus and method
Inventor: KALEN BODO
IPC: B04C5/28
Filed: 1992-10-20
Abstract: PARTICULATE FILTRATION APPARATUS AND METHOD            ABSTRACT OF THE INVENTION       A method and apparatus are provided for separating particulate material from hot gas. Provisions are made for accommodating relative thermal expansion between a hot particular laden gas chamber, a particulate discharge chamber and a clean gas chamber.  A main housing supports an interior subhousing supported from the top of the main housing while a further discharge chamber housing is supported from a lower part of the subhousing in such a manner that they are free to expand and contract independently of one another.  Gas and particulate separators which are free from load bearing stresses are designed to receive the particulate laden gas and pass particulates to the particulate discharge chamber for bottom discharge and the gas to the clean gas chamber for discharge at the top of the main housing.  Provisions are made for auxiliary discharge of particulates bypassing the separators at a bottom of the clean gas chamber.  Relative expansion is provided for at the lower extremities of the main housing and subhousing and discharge chamber housing with gas sealing therebetween.  Downward flow of the particulate laden hot gas past the separators is employed to drive the particulates in a direct line to minimize dissipating energy in peripheral or vertical flow.

Title: Wet-base, down-fired water heater
Inventor: STRETCH GORDON W
IPC: F24H1/20
Filed: 1993-01-15
Abstract: A fuel-fired, forced draft water heater is provided with a specially designed burner structure and combustion product flow path  that  permit  the  heater  to  operate  with  improved  fuel efficiency, lowered CO and NOx emissions, and an improved water heat input distribution along the vertical length of the heater.

A submerged vertical burner tube extends downwardly from the vent plenum and has an open lower end extending into a submerged turn bowl disposed at the bottom end of the tank interior.  Extending upwardly from the turn bowl within the tank interior are a plurality of vertical flue tubes that communicate the interiors of the turn bowl and the vent plenum.  A vertically elongated perforated conical burner is disposed within the burner tube and is supplied with a throughflow of a pressurized fuel/air mixture that is ignited by an igniter mounted on the top end of the burner.   During operation of the water heater, hot combustion products discharged from the conical burner are sequentially flowed downwardly through the burner tube into the submerged turn bowl, upwardly through the flue pipes into the vent plenum, and then outwardly through the vent plenum outlet passage.

Title: A process for removal of so2 and nox from combustion flue gases and an apparatus used therefor
Inventor: ZIMEK ZBIGHIEW
IPC: B01J19/12
Filed: 1992-05-21
Abstract: Removal of SO2 and NO x from combustion flue gases is effected to be subjected to irradiation by an electron beam and to the action of microwaves applied in the form of a continuous and/or pulsed stream. The stream of flue gases irradiated by the electron beam in the radiation zone is subjected to the action of microwave energy in the whole cross section of the stream of the flue gases. This results in a decrease in the dose rate "average power of the electron beam" and a reduction in the costs of accelerators while retaining the same removal efficiency. Further, the apparatus for removal of SO2 and NO2 from combustion flue gases is provided in a radiation process in which a stream of accelerated electrons and microwave energy are used simultaneously.

Inventor: CIVANLAR MEHMET R
IPC: H04N19/60
Filed: 1993-05-25
Abstract: Technique améliorée de changement de fréquence efficace. Selon la technique proposée, le nombre de coefficients à inclure dans chaque sous-bloc peut être déterminé au choix, et un code désignant le nombre de coefficients relatifs à chaque couche est intégré en double chaîne au début de chaque séquence vidéo codée. Cette technique fait en sorte que les séries initiales de coefficients d'ordre zéro de la couche peuvent demeurer intactes en formant un sous-bloc pour chaque échelle à partir d'un nombre sélectionné de coefficients pendant un balayage continu. Ces sous-blocs peuvent être décodés selon une méthode conventionnelle, soit par une transformation en cosinus discrets inverse de sous-blocs obtenus par l'ajout de zéros de remplissage, et/ou par l'élimination de coefficients excédentaires dans chacune des échelles. La technique proposée permet d'améliorer davantage la qualité du codage parce qu'un signal implicite de fin de bloc peut être utilisé pour séparer des blocs, ce qui fait en sorte qu'il n'est pas nécessaire, dans la plupart des cas, de transmettre un signal de fin de bloc explicite.
