Patent number: 7459011Abstract: The natural gas arriving through pipe 1 is deacidified by being brought into contact with a solvent in zone C. The solvent charged with acid compounds is regenerated in zone R. The acid gases, released into pipe 5 upon regeneration, include a quantity of solvent. The method enables the solvent contained in the acid gases to be extracted. In zone ZA, the acid gases are brought into contact with a non-aqueous ionic liquid whose general formula is Q+ A?, where Q+ designates an ammonium, phosphonium, and/or sulfonium cation, and A? designates an anion able to form a liquid salt. The solvent is removed from the acid gases evacuated through pipe 6. The ionic liquid charged with solvent is regenerated by heating in an evaporator DE. The ionic liquid regenerated is recycled through pipes 8 and 9 to zone ZA. The solvent is evacuated through pipe 13.Type: GrantFiled: February 14, 2005Date of Patent: December 2, 2008Assignee: Institut Francais du PetroleInventors: Renaud Cadours, Fabrice Lecomte, Lionel Magna, Cécile Barrere-Tricca

Patent number: 7381776Abstract: The invention provides crosslinked rubber moldings for golf balls obtained by spherically molding and crosslinking a rubber composition containing a base rubber, a co-crosslinking agent and a crosslinking agent, then impregnating the crosslinked rubber molding with a rubber compounding chemical and inducing a chemical reaction. The rubber compounding chemical-impregnated crosslinked molding has a higher surface hardness than the crosslinked molding prior to impregnation. The invention also provides a method for manufacturing such crosslinked rubber moldings for golf balls. The invention enables a sufficient rise in the surface hardness of the core to be achieved, thus increasing the degree of freedom in the design of the golf ball.Type: GrantFiled: April 8, 2005Date of Patent: June 3, 2008Assignee: Bridgestone Sports Co., Ltd.Inventors: Atsushi Nanba, Jun Shindo

Patent number: 7377966Abstract: An adsorptive filter/member for adsorbing a gaseous adsorbate. The filter includes two layers of a flexible polymeric material to form an area therebetween. Fasteners are located at predetermined areas across the two layer outer surfaces, the fasteners extending from the outer surface of one layer to the outer surface of the other layer. The fasteners subdivide the area into a plurality of substantially enclosed chambers. Adsorptive media is disposed within each of the plurality of chambers. The chambers are adapted to substantially evenly distribute adsorptive media throughout the filter. Throughbores extend through the filter, and receive attachment members for mounting the filter to a surface. A gaseous adsorbate flow path is in gaseous communication with one of the outer surfaces of the two layers. Each of the two layers' polymeric materials includes pores that are permeable to the gaseous adsorbate, yet are substantially impermeable to the adsorptive media.Type: GrantFiled: August 26, 2004Date of Patent: May 27, 2008Assignee: Honeywell International, Inc.Inventors: Robert L.

Patent number: 7377958Abstract: An apparatus is provided for removing airborne moisture from a designated area. In one embodiment, the apparatus includes a bucket, a liquid absorption medium (such as ground corn cobs) placed in the bottom of the bucket to form a media bed, a tray placed over the absorption media bed, and a moisture absorption medium (such as calcium chloride) placed in the bucket over the tray. A method is also provided for absorbing moisture from a humid environment using the apparatus. When the apparatus is exposed to humid conditions, the CaCl2 will absorb moisture and become hardened. As the CaCl2 media hardens, it will expand. However, its lateral expansion is restricted by a side wall of the tray. Over further time, the CaCl2 will begin to dissolve into a brine. The brine will gravitationally seep through the through-openings in the tray and be captured by the corn cob medium.Type: GrantFiled: February 17, 2005Date of Patent: May 27, 2008Inventor: Joaquin P. Cunanan
