Patent number: 6811637Abstract: A source for supplying lengths of adhesive tape applies such adhesive elements with their outer surfaces facing outwards onto a gripping element consisting of a rotating drum. The drum in question applies the adhesive element on the outer surface of a reel of web material in such a way as to establish adhesive connection with the latter. As a result of a subsequent movement of the drum with respect to the reel, there is formed a loop of web material. Since the loop is separate from the reel, it can undergo a cutting action with the consequent formation of a free flap that can be used for unreeling the web material from the reel. After the web material has been unreeled for a certain stretch and the portion on which the aforesaid adhesive element was applied has been eliminated, on the same web material there may be applied a further adhesive element which is left uncovered for at least part of its surface provided with adhesive.Type: GrantFiled: March 21, 2002Date of Patent: November 2, 2004Assignee: Fameccanica.Data S.p.A.Inventors: Pietro Pelagatti, Giancarlo Casuscelli

Patent number: 6811684Abstract: There is provided a process for converting hydrocarbons using a catalyst comprising macrostructures having a three-dimensional network of particles comprised of porous inorganic material. The particles of the macrostructures occupy less than 75% of the total volume of the macrostructures and are joined together to form a three-dimensional interconnected network comprised of pores having diameters greater than about 20 Å. The macrostructures can be made by forming an admixture containing a porous organic ion exchanger and a synthesis mixture capable of forming the porous inorganic material; converting the synthesis mixture to the porous inorganic material; and removing the porous organic ion exchanger from the inorganic material.Type: GrantFiled: April 25, 2002Date of Patent: November 2, 2004Assignee: ExxonMobil Chemical Patents Inc.Inventors: Gary David Mohr, Wilfried Jozef Mortier, Xiaobing Feng, Per Johan Sterte, Lubomira Borislavova Tosheva

Patent number: 6811685Abstract: A self-cleaning strainer which may be installed upstream of a heat exchanger to prevent debris greater than a critical size from reaching the heat exchanger. The strainer is preferably mounted just upstream of a heat exchanger in order to minimize the possibility of debris reaching the heat exchanger. The strainer comprises a screen element which can be advanced across the flow path of the fluid between two rollers. The screen element is placed so that the fluid must flow across the screen element face to continue through the process pipe; the screen may be perpendicular or parallel to the fluid flow axis of the strainer body or at an intermediate angle to it. Flow blocking members are used so as to direct the flow to pass through the screen element.Type: GrantFiled: August 19, 2003Date of Patent: November 2, 2004Assignee: ExxonMobil Research and Engineering CompanyInventors: Amar S. Wanni, Thomas M. Rudy, Marciano M. Calanog
