Patent MX-9703267-A (MX)
Title: Fuel pretreater apparatus and method.
Inventor: PANTONE PAUL
Filed: 1995-11-06
Abstract: A novel fuel pretreater apparatus and method for pretreating alternate fuel (63) to render it usable as the fuel source for an internal combustion engine (20). The apparatus includes a volatilization chamber (12) into which the alternate fuel is received. An exhaust plenum (17) encloses the volatilization chamber so that thermal energy supplied by exhaust from the internal combustion engine can be used to volatilize the alternate fuel. A bypass stream of exhaust is diverted through the alternate fuel in the volatilization chamber and is used to carry the volatilized fuel through a reactor prior to its being introduced into the internal combustion engine. The reactor is interposed in the exhaust conduit and is prepared from a reactor tube having a reactor rod mounted coaxially therein in spaced relationship. The exhaust passing through the exhaust conduit provides thermal energy to the reactor to pretreat the alternate fuel.

Title: Matched permeability liner/absorbent structure system for absorbent articles and the like.
Inventor: PAUL SUSAN CAROL
IPC: A61F13/15
Filed: 1998-06-19
Abstract: The present invention is directed to a matched permeability liner/aborbent structure system, suitable for use in absorbent articles, in which the permeability of the bodyside liner is correlated with the permeability of the subjacent layer of the absorbent structure, such as a surge layer. The inventors have observed that by appropriately matching the permeability of the liner material to the permeability of the subjacent layer, liquid intake performance of the liner and subjacent layer materials can exceed liquid intake performance of the subjacent layer material alone. Thus, in accordance with an embodiment of the present invention, the permeability of the bodyside liner is set within a specified range of that of the subjacent layer such that the liner/subjacent layer liquid intake performance is improved. In accordance with another embodiment of the present invention, the permeability of the bodyside liner is matched to or correlated with the permeability of the subjacent layer such that the liner/subjacent layer liquid intake performance is improved at least about 50 percent over the liquid intake performance of the subjacent layer alone. In accordance with yet another embodiment of the present invention, the permeability of the liner material is matched to or correlated with the permeability of the subjacent layer such that liquid intake performance of the liner/subjacent layer combination is improved at least about 65 percent over the liquid intake performance of the subjacent layer alone. As disclosed herein, by properly selecting the permeability of the liner material, as compared with the permeability of the subjacent layer material, the liquid intake rate of the liner material not only does not limit or inhibit liquid intake into the subjacent layer and underlying components of the absorbent structure, but provides an unexpected increase in liquid intake performance over that of the subjacent layer alone. The bodyside liner and subjacent layer can suitably be formed of fibrous nonwoven webs.

Title: Rapid direct cooling of cracker effluent - to avoid tar and coke deposition
IPC: F28C3/06
Filed: 1974-02-20
Abstract: Cooling process is applicable to the cooling of cracker effluent from the prodn. of ethylene. The assembly is connected to the end of the effluent pipe; the gases enter the cooling chamber and the rapid cooling oil is pumped simultaneously into a reservoir from which it flows over an annular ring to form a film over the inner wall of the chamber. This film prevents the accumulation of tars, heavy polymers, coke and other constituents which may foul the walls of the cooling chamber. The film may be 1/4" thick and the combined gas and liq. effluent, now partially cooled, leave at the lower end of the transfer pipe. Fouling of the walls being prevented, there is no risk of blockage and the rate of transfer of heat through the walls is not affected.
