20100005898 | System and method for conditioning and detection of moisture damage in asphalt mixes - An apparatus and method for determination of susceptibility of asphalt concrete materials to moisture damage. An asphalt sample of known bulk specific gravity (density) is placed inside a chamber filled with water, which is capable of heating the sample to a pre-determined temperature. The chamber is pressurized by introduction of air pressure to a flexible membrane that decreases the volume within a chamber containing the sample and water, increasing the pore pressure in the sample. The pressure is then released and allowed to come to ambient pressure. This process is repeated a predetermined number of times (cycles). When a selected number of cycles are complete, the asphalt sample is removed from the chamber and its bulk specific gravity (density) measured again. The difference between the density before and after conditioning is an excellent method of rating the degree at which moisture would deteriorate asphalt samples due to introduction of moisture. The cyclic nature of the increased/decreased pore pressure is observed to significantly decrease bulk specific gravity (density) for poor quality asphalt designs. Furthermore, the sample conditioned by this method can be used for other conventional mechanical test methods, such as tensile strength and modulus determination. Computerized controls are used to automate the procedure and to record and display data from sensors. | 01-14-2010 |

20090295052 | Device For Displacing Jaws Of A Clamp - A mechanical device for displacing jaws of a spring biased clamp includes a housing for receiving handles of the spring biased clamp. The housing has a platform moveable toward and away from a wall to move the handles of the clamp toward and away from one another, to move the jaws of the clamp away from and toward one another, respectively. A control member activates and deactivates a force applying member operationally connected to the platform, wherein activating the force applying member moves the platform toward the wall and deactivating the force applying member moves the platform away from the wall of the housing. The device is used to apply clamps to marginal edge portions of a stack of two one or more sheets to provide a clamped subassembly. The clamped subassembly in one embodiment is laminated to provide an aircraft transparency. | 12-03-2009 |

20100225529 | UNSWITCHED, ULTRA LOW POWER, LONG RANGE RADAR SYSTEM - An ultra low power, long range, robust radar system, for applications such as ionospheric sounding. The HF transmit signal and the received (reflected) signal are both unswitched and high frequency and share a path to a common loop antenna. The transmit signal originates at a local oscillator (LO), and is sufficiently low power to not saturate the receive signal path. A balun divides the local oscillator signal between the transmit path forward to the antenna and a mixer path, and also divides the received signal between the mixer path and the LO path. A mixer converts the mixed LO and received signal to baseband. | 09-09-2010 |
