Title: Method and system for controlling liquid fuel and vapor flow during refueling of a motor vehicle fuel tank
Inventor: BENJEY ROBERT P
IPC: B60K15/04
Filed: 2003-01-30
Abstract: A vapor vent system for a fuel tank having a vapor vent valve in the top of the tank with its outlet connected to a storage canister. In one embodiment the vent valve outlet is connected to the canister through a hose which is also connected to the filler tube for vapor recirculation. In another embodiment a conduit is connected at one end through the tank wall and the opposite end to the filler tube for vapor recirculation. A nozzle seal is provided in filler tube above the recirculation connection. The filler tube is sized, below the one-way valve connection, to effect a dynamic seal with refueling nozzle discharge to entrain vapor from the recirculation connection valve and any air leaking past the nozzle seal in the upper end of the filler tube and to create a negative pressure when vapor recirculation is cut off to ensure activation of the automotive nozzle shutoff.

Title: Hybrid neuroprosthesis for the treatment of brain disorders
Inventor: KOVACS LORANT
IPC: A61K9/22
Filed: 2001-08-09
Abstract: A miniature apparatus for the treatment of brain disorders is provided which is a combination of electronic and pharmacological devices placed and powered entirely within the human body. The apparatus is based on the dual, electrical-molecular, nature of intercellular communication in the brain. The hybrid neuroprosthesis monitors the electrical activity of a dysfunctioning brain area, analyzes the incoming electrical signals, and delivers drug molecules into the dysfunctioning area to correct its function. The apparatus delivers drugs into the brain in such a way that the timing and duration of the drug deliveries are determined by the brain's own electrical activity. The hybrid neuroprosthesis includes: (a) an electrophysiological recording electrode implanted in a dysfunctioning brain site; (b) a miniature electrical signal conditioner to amplify, filter and digitize the incoming electrophysiological signals; (c) a cannula or catheter implanted in the dysfunctioning brain site;  (d) a miniature, refillable pump for driving drug solutions through the cannula or catheter; (e) a microcontroller which analyzes on-line the digitized electrophysiological signals and either activates or inactivates the pump on the basis of the analyzed electrophysiological data; (f) a miniature radiotelemetry system which provides data transfer between the apparatus and the outside world; and (g) a rechargeable power supply to power the components of the apparatus. The recording electrode can be complemented with a neurochemical sensor to transmit not only electrophysiological but also neurochemical information from the dysfunctioning brain area to the microcontroller. The components of the apparatus are encapsulated in medical grade silicon.

Title: Method for the regeneration of residues containing sulfur and an atomizing burner suited for executing the method
Inventor: GRUENIG HEINZ
IPC: F23G5/14
Filed: 2001-09-07
Abstract: In a prior art method for regenerating a residual substance that contains sulfur, a drop stream containing the residual substance is introduced into a reactor, fed to a reaction zone comprised of hot flue gases, which are produced by combusting a fuel, and are heated therein in order to thermally cleave the sulfurous compounds of the residual substance. Expanding upon this, an increase in performance and an improvement in the economic viability of the method are attained by introducing a drop stream containing fuel into the reactor at the same time as the drop stream containing the residual substance and feeding it to a pre-reaction zone, which is produced by introducing an oxygen-rich gas stream, whereby the residual substance is, in part, thermally cleaved inside the pre-reaction zone and is subsequently fed to the reaction zone. An atomizing burner, which is suited for carrying out said method and which has a long serviceable life, is characterized in that a protective gas nozzle, which coaxially surrounds the inner nozzle, is provided between said inner nozzle and the outer nozzle, and in that the inner nozzle is connected to an inlet for a residual substance/fuel mixture, and the outer nozzle is connected to an inlet for an oxygen-rich gas stream.
