| 20100236832 | PERCUSSIVE DRILL BIT PROVIDED WITH AN IMPROVED CHUCK ASSEMBLY - A percussive drill bit provided with an improved chuck assembly for a down-the-hole drill hammer. The bit has a head at its forward end with a shank extending from the head. The shank is screw threaded along its length. A reciprocating chuck is provided as a sleeve with internal screw thread as corresponding to those of the shank. The shank is releasably secured in the chuck with the read end of the shank providing a striking face. An arrangement of external splines on the chuck, and a retaining shoulder at its rear end, provide for the required guided movement of the chuck within a drill hammer wear sleeve. | 09-23-2010 |

| 20100011888 | METHOD AND DEVICE TO EXTRACT COMPONENTS CONTAINED IN A FLUID - Applicants' teachings relate to a method and device to extract components contained in a fluid. More particularly, the applicants' teachings are directed towards a method and sampling device for quick extraction of targeted components from their in vivo surroundings. In accordance with various embodiments of applicants' teachings a sampling device and method to extract components, such as, for example, analytes, from a fluid is provided. The device is interfaced with a fluid source, such as, for example, but not limited to, a circulatory system of an animal, to enable extraction of target molecules with minimal loss of fluid (e.g., blood) to the source. The device facilitates an interface between the circulatory system of an animal and a suitable sampling probe such as, for example, a solid phase microextraction (SPME) probe. The targeted compounds are desorbed in small volumes of solvents that can be analyzed with highly specific instruments. In particular, in various embodiments of applicant's teachings a device to extract components contained in a fluid is provided. The device comprises a housing defining a cavity, with the housing having at least one opening to allow fluid flow into and out of the cavity. The device also comprises a probe insertable into the cavity of the housing. Moreover, the device comprises a channel, with the channel adapted to connect the cavity to a fluid pump, so that when the probe is inserted into the cavity the fluid pump causes fluid to flow into and out of the cavity through the at least one opening and contact the probe in the cavity. | 01-21-2010 |
