Likewise, a flexural set exists between the second and third rigid elements. Meanwhile, the rigid elements have section moduli sufficiently great as to be orders of magnitude larger than the flexural stiffness or section modulus of the flexures, thus providing flexures that operate in the elastic mode and introduce no joint type accuracy errors in adjustment. | 08-09-2012 |
20120255290 | LATCHING ACTUATOR - A latching actuator capable of repeated operation in a cryogenic, remote, or difficult-to-access environment, capable of enduring many cycles without user intervention or maintenance, capable of latching in a fixed position without consuming additional power, or to operate independent of external environmental conditions. In selected embodiments, a latching actuator may comprise an expansion chamber that houses a working substance capable of undergoing a phase change, a logic mechanism, a biasing assembly, and an output pin. In one embodiment, a wax motor may provide the motive force to toggle a latching mechanism. An actuator may be capable of positioning an output pin in two or more discrete latching positions and may be used to create a thermal connection between two structures, to engage or disengage a clutch, or to position an optical element in an optical instrument. An actuator may also be used as a launch lock apparatus. | 10-11-2012 |
20130242419 | KINEMATIC OPTIC MOUNT - A two-axis, optical mount provides two flexural elements monolithically and homogeneously formed of a single material with, and interconnecting, three rigid segments. Between each pair of rigid segments, beginning with the first and second, a set of extensions is formed to have a cross section that permits simple, easy, independent adjustment therebetween. Likewise, a flexural element exists between the second and third rigid elements. Meanwhile, the rigid elements have section moduli sufficiently great as to be orders of magnitude larger than the flexural stiffness or section modulus of the flexural elements, thus providing flexures that operate in the elastic mode and introduce no joint type accuracy errors in adjustment. | 09-19-2013 |

20130160644 | SYSTEM AND METHOD FOR IMPROVING THE PERFORMANCE OF DESICCANT DEHUMIDIFICATION EQUIPMENT FOR LOW-HUMIDITY APPLICATIONS - A method and apparatus for energy-efficient desiccant dehumidification of air or other gases to low humidity levels is disclosed. The method and apparatus includes a desiccant rotor (wheel) having more than one dehumidification zone or sector. Separate dehumidification sectors may be used to dehumidify separate air or gas streams, or they may be used to dehumidify a single air or gas stream by passing it through more than one sector. All or a portion of the discharge air or gas from a dehumidification sector is used for all or a portion of reactivation inlet air or gas prior to heating. The desiccant wheel may include more than one reactivation sector, with separate air or gas sources for each sector. The desiccant wheel may include a purge sector between the reactivation and dehumidification sectors to improve the thermal efficiency of the dehumidification process. | 06-27-2013 |
20140345153 | METHOD AND DEVICE FOR MOISTURE DETERMINATION AND CONTROL - The present invention relates to a method for moisture determination and control using real time measurement of the moisture content of the material being processed. The present invention also provides a device that is used for moisture determination and control based on real time measurement of moisture content of a material being processed. The present invention is particularly suitable for controlling the moisture content of a material in a drying process, such as in a drying hopper, where the material moisture content is measured at an inlet and an outlet of the drying process. The drying process is further controlled by anticipating the drying load by measuring the moisture content of the incoming material to be dried. | 11-27-2014 |
20150153051 | APPARATUS AND METHOD FOR CONTROL OF SOLID DESICCANT DEHUMIDIFIERS - The present invention generally discloses desiccant dehumidifiers control systems. In particular, the present invention relates to solid desiccant dehumidifiers which use a rotor (commonly called a wheel) to dehumidify a process airstream. The invention provides a novel apparatus for control of desiccant dehumidifiers and to an improved method of control of such dehumidifiers, and also to dehumidifiers provided with such control systems. | 06-04-2015 |
