Publication number: 20070227355Abstract: The invention relates to a method for displacing acid gas constituents from natural gas to acid gas removal installations equipped with Claus installations with free capacities. To this end: a portion of the acid gas is removed from a first flow of natural gas containing acid gas; the acid gas removed from the first flow of natural gas is fed to at least one other acid gas removal installation, whereby this feeding results in the acid gas removed from the first flow of natural gas being mixed with at least one second flow of natural gas with which it is transported to at least one other acid gas removal installation. The removal of the acid gas contained in the first flow of natural gas is preferably carried out by means of an absorption method during which the portion of the acid gas to be removed is washed out from the first flow of natural gas by means of a regenerated non-chemically acting absorbing medium.Type: ApplicationFiled: November 27, 2004Publication date: October 4, 2007Inventor: Johannes Menzel

Publication number: 20070227356Abstract: A gas-solids reaction system is provided for improving product recovery in a multiple reactor reaction system. The solids of the product gas-solids flows from the multiple reactors are separated out in a separation vessel having a baffled transition zone. Additional product vapor is stripped from the solids as the solids pass through the baffled transition zone. The solids are then returned to the multiple reactors.Type: ApplicationFiled: March 28, 2007Publication date: October 4, 2007Inventor: James H. Beech

Publication number: 20070227357Abstract: System for separating a gas mixture comprising a plurality of separation stages, each having a reference number n from 1 to N, inclusive. Each stage has a housing, a turbomolecular pump assembly therein having inlet and outlet ends, a first chamber adjacent the inlet end and having an inlet port and a first outlet port, and a second chamber adjacent the outlet end and having a second outlet port. The inlet port of a separation stage n is connected with the first outlet port of an adjacent stage n+1, and the second outlet port of the stage n is connected with the inlet port of the stage n+1. The inlet port of any stage may serve as a feed port. The first chamber of stage n=1 and the second chamber of stage n=N have first and second product outlets, respectively.Type: ApplicationFiled: March 31, 2006Publication date: October 4, 2007Inventor: Wayne McDermott

Publication number: 20070227363Abstract: An espresso-coffee making apparatus comprising a brew water tank at least one heating device for the purpose of heating the brew water, and a pump operatively engaged to the brew water tank with both its inlet and outlet. The pump outlet is attached to a housing such that the pump's discharge moves past the heating device for effective mixing at the heat source. The housing may also include turbulators for further enhanced mixing. Thus, maximum temperature homogeneity within the brew water tank is achieved. The apparatus may further comprise a biasing device operatively engaged to a piston-type pump via a linkage mechanism. Wherein the biasing device is energized by the operator, by means of a lever and the pressurized water produced used to brew espresso. Further, the pressure of the water produced by the pump is modified by the linkage mechanism such that the brew pressure as a function of displaced liquid is controlled. Thus more optimal brewing pressure profiles can be achieved.Type: ApplicationFiled: April 3, 2007Publication date: October 4, 2007Inventor: Raffaello Verna

Publication number: 20070227364Abstract: In a steam cooker, for heating of a food which is a mass of granular matters or linear matters such as rice or chow mein, a steam superheater is not turned on or is turned on with a very weak electric power so that steam supplied from steam supply pipes (94A to 94C) is substantially not superheated. Steam of 80° C. to 90° C. derived from the steam supply pipe (94B) is jetted out right downward from an opening (111a) of a steam jet pipe (111). Then, steam located around an end portion of the steam jet pipe (111) in a tray-shaped case (51) is pulled in by steam jetted out from the opening (111a), so that a large amount of steam is jetted against a bowl of rice or a dish of chow mein. As a result, surfaces of, for example, rice grains are prevented from immediately going beyond 100° C., so that condensation at the surfaces of the rice grains is efficiently achieved, and supply of condensed latent heat and penetration of condensed water (hot water) to the rice grains is efficiently achieved.Type: ApplicationFiled: May 16, 2005Publication date: October 4, 2007Inventors: Yuji Andoh, Shinya Ueda, Kazuyuki Matsubayashi
