| 20110204892 | SPIN ECHO SPI METHODS FOR QUANTITATIVE ANALYSIS OF FLUIDS IN POROUS MEDIA - A method of measuring a parameter in a sample by imaging at least a portion of the sample using a spin-echo single-point imaging (SE-SPI) pulse sequence. This method involves applying a pure phase encoding to the SE-SPI pulse sequence, acquiring a multiplicity of echoes, and determining the spatially resolved T2 distribution. In another embodiment, individual echoes are separately phase encoded in a multi-echo acquisition and the SE-SPI pulse sequence is a hybrid SE-SPI sequence. In another embodiment, an external force can be used to build up a distribution of saturations in the sample, and a T2 distribution can be measured for the sample, which is then used to determine a parameter of the sample. A spatially resolved T2 distribution can also be measured and a resulting spatially resolved T2 distribution used to determine the T2 distribution as a function of capillary pressure. | 08-25-2011 |

| 20100148777 | MAGNET ARRAY - A magnet array is disclosed which is suitable for inter alia producing a remote field for use in unilateral magnetic resonance. In the “Magnet Array”, two separated magnets, which are magnetized along a substantially same collinear magnetization direction, produce a field with a local maximum centered above and between them. The field produced by the two separated magnets is substantially parallel to the collinear magnetization direction of the two separated magnets. A third magnet is centered between the two separated magnets. The third magnet has a magnetization direction which is substantially parallel to the collinear magnetization direction of the two separated magnets. The third magnet produces a field which is substantially parallel to the collinear magnetization direction of the two separated magnets, and adds to the increasing field below the local maximum point produced by the two separated magnets. The field of the third magnet, which decays with distance, adds to the increasing field below the local maximum point. The position of the third magnet is selected in order to generate a total field which has at least one of its first and second spatial derivatives with respect to the distance above the magnet array substantially equal to zero. | 06-17-2010 |

| 20080303520 | Methods suitable for measuring capillary pressure and relative permeability curves of porous rocks - Single-shot methods suitable for determining capillary pressure and relative permeability curves are proposed. For steady-state gas flow, with stationary water or oil remaining in a porous rock core and the outflow boundary condition (capillary pressure is zero) is maintained by washing the outlet face of the core with the stationary phase, the gas pressure distribution, P(x), is determined by SPRITE (Single-Point Ramped Imaging with T | 12-11-2008 |

| 20110226556 | DETACHABLE BOOM APPARATUS FOR FORK TRUCKS - A boom apparatus is provided for a fork truck having an elevator frame, a carriage movable via the elevator frame, and fork-supporting transverse members on the carriage. The apparatus includes a boom mount mechanically attached to the transverse members, and a boom mechanically attached to the boom mount. The boom mount includes a vertical plate, and top and bottom braces forming opposing hooks for engaging the transverse members. The top brace also includes a narrow section with horizontal hole that aligns with holes in brackets on the boom. A lock pin extends through the aligned holes to lock the boom to the mount. The mount includes a bottom T pin that fits into a slot at the boom's bottom to secure the boom in a vertical orientation on the mount. By this arrangement, the boom and boom mount can be securely and easily attached to a fork truck without welding. | 09-22-2011 |
