20090140186 | ENERGY EFFICIENT SOLENOID FOR MECHANICALLY ACTUATING A MOVABLE MEMBER - A solenoid actuator includes an electrical circuit with a first power input terminal, a second power input terminal, a first coil wound around a first axis and configured to generate a first magnetic field while electrical current flows through the first coil, and a second coil wound around a second axis configured to generate a second magnetic field while electrical current flows through the second coil. An electric switch connects or disconnects the first coil and second coil in series. Thus, the electric switch can energize or de-energize the second coil. A movable member, such as a rod, bar, spool, or hollow tube, influenced by the magnetic fields generated by the first and second coils is configured to move with respect to the first and second coils from a first position to a second position in response to the magnetic field generated by the first coil. | 06-04-2009 |
20080236771 | SYSTEM AND METHOD FOR CONTROLLING A PROCESSOR INCLUDING A DIGESTER UTILIZING TIME-BASED ASSESSMENTS - A system for controlling a processor having at least one sampling port connected to a stage of the processor in order to sample a reactant product from the processor. The system includes a controller configured to control a processing parameter of the processor based on measurements of at least one property of the reactant product such that changes to the processing parameter maintain a target value for the at least one property of the reactant product. The system further includes a dead time compensator. The dead time compensator is configured, based upon a prescribed dead time related to a time before at least one effect of at least one change to the processing parameter is fully realized, to evaluate the reactant product to determine if the effect has been realized at a plurality of sequential times offset from the dead time. | 10-02-2008 |
