Abstract: The present invention relates to a process for preparing magnetite (Fe3O4) or derivatives thereof, comprising the steps: a) preparing an aqueous solution A of a Fe(III) salt, b) preparing an aqueous solution B of an iodide salt, c) mixing solutions A and B to obtain a first precipitate, d) separating the first precipitate to obtain a filtrate, e) hydrolyzing the filtrate obtained in step d) by adjusting the pH to about 8.5-9 or above, preferably 9, in order to obtain a second precipitate, and f) separating the second precipitate.

Abstract: A filter apparatus has a housing, an inlet port on one side of the housing and an outlet port on an opposed side of the housing. Sheet media is disposed in the housing having a first opening through the sheet media. Also dispersed in the housing is a bag media comprising an enclosed bag with a second opening into the bag. The first opening and the second opening are connected in fluid communication with each other and the sheet media is disposed before the bag media in the direction of flow through the housing so that both media are mounted inside the housing. Some fluid entering the inlet passes through both openings and through the bag media and into the outlet, and other fluid entering the inlet passes through the sheet media and then to the outlet.

Abstract: An automated and flexible architecture is provided that enables a plurality of component tests to be executed in various testing orders while imposing a test framework to mitigate adverse effects or results on previously developed tests. In one aspect, a computerized test system is provided. The system includes a test engine to execute a plurality of component tests. One or more application programming interfaces (API) are provided to selectively determine at a subset of the tests to execute, an execution order of the tests, or a fault response for the tests, if desired. The API determines a phase execution for the tests, where the phase execution can include a set up phase, an execution phase, a validation phase, a publishing phase, and a clean up phase, for example.

Abstract: A lip seal has an internal spring element disposed in an elastomeric ring.

Abstract: An automated data generation system and methods are provided to facilitate generation of test data sets for computerized platforms while mitigating the need to store massive quantities of potentially invalid test data. In one aspect, a computerized test system is provided. A rules component is provided to specify one or more data domains for a test data set. A data generator employs the rules component to generate the test data set, where the test data set is then employed to test one or more computerized components.

Abstract: A fluid filter includes a filtered flow and a bypass flow. In particular, a fluid filter insert includes a first end cap, a second end cap, a screen disposed between the first and the second end caps, and a filter media surrounding the screen. Further, a method of filtering a fluid includes passing a first portion of the fluid through a fluid filter inlet, passing a second portion of the fluid through a filter media, and passing the first and the second portions through a filter outlet. In addition, a fluid filter includes a bypass inlet, a filter media inlet coaxial with the bypass inlet, an outlet axially spaced from the bypass inlet, and a housing surrounding the bypass inlet, the filter media inlet and the outlet. Further, the fluid filter provides that the bypass inlet is dimensioned to permit a predetermined amount of flow.
