Abstract: An improved and optimized design for a universal infusion coffee filter pack designed to fit and provide for consistent brewing of quality coffee in a variety of American style and European style coffeemakers. The infusion coffee pack (34) comprises a first circular piece (40a) of filter paper, having its surface area stretched and increased by at least 3% to form a rounded pocket, and sealed to a second circular piece (50a) of filter paper to form a substantially one half inch (1.27 cm) sealed flange (32) therearound. A metered quantity of coffee grounds (36) is sealed within the rounded pocket, and is provided with a head space (38) of substantially fifty percent or greater of the volume within the round coffee pocket. The first (40a) and second (50a) circular pieces of filter paper each preferably have a diameter of approximately five inches (12.7 cm), and are filled with a metered amount of ground coffee to brew five cups of water. In this optimized design, the presence of the one half inch (1.27 cm) flange (32) in combination with the increased surface area caused by stretching results in a brewed coffee having an increase in soluble solids extraction and a decrease in the standard deviation of soluble solids extraction.

Date Jun. 28, 1990.A two-stage method of producing N2O5 in nitric acid from N2O4 in nitric acid consists of a first production stage in which the anodic oxidation of N2O4 in nitric acid and cathodic reduction of nitric acid are separated by a non-ionic or anionic ion exchange membrane, and a second production phase in which the product of the first stage anodic reaction is subjected to further anodic oxidation, the anodic and cathodic reactions being separated by a cationic ion exchange membrane. The use of a cationic membrane in the second stage promotes, through leakage of N2O4 to the catholyte, an increase in N2O5 concentration and decrease in N2O4 concentration within the anolyte acid while avoiding a significant loss of current efficiency. The two stages may be connected in series and operated continuously to produce a nitric acid solution containing typically 32 wt. % N2O5 and less than 2 wt. % N2O4.

According to the invention, at least part of the cooling air is taken via an exit slot which is divided into individual separately fed segments in the peripheral direction of the film bubble and the supply of additional cooling air via the exit slot is, for example, controlled per segment using radial blowers. In this manner it is possible accurately to regulate the cooling action and thus the film thickness in the individual peripheral regions of the film bubble.
