Abstract: A fuel injector includes a collar, which may be formed of a porous, sintered material, the collar being located around the needle and allowing a restricted fluid pathway, such as orifices through the collar, between first and second volumes of fuel, the collar being located in a section of the nozzle body which has a greater cross-sectional area than the rest of the bore.

Abstract: An apparatus for moving the esophagus includes an elongate body having a distal tip, a controlled curvature section, and a flexible section. A handle is coupled to the flexible section to adjust the curvature of the controlled curvature section. The length of the controlled curvature section is less than the length of the thoracic portion of the esophagus. Further, a method of adjusting the curvature of the esophagus during a therapeutic procedure in a treatment area outside of the esophagus includes positioning within the esophagus an elongate body having a distal tip, a controlled curvature section, and a flexible section and adjusting the curvature of the controlled curvature section to increase the distance between the esophagus and a treatment area outside of the esophagus.

Abstract: Reticulated vitrified carbon compositions which contain particles of Cu, Sn, Zn, Pb, Ni, Fe, or alloys or mixtures thereof dispersed therein and reticulated vitreous carbon compositions wherein some or all of said metal or alloy particles have been converted into salts or mixtures of salts thereof. Processes for the preparation of such compositions.

Abstract: A carbon based electrode for the electrochemical reduction of sulfur or oxygen, which comprises an electrode core and, in electrical contact therewith, a structure comprising a porous particulate activated carbon bonded with a polymeric binder material, characterised in that the structure is at least 1 mm thick, in that the particulate activated carbon is prepared from a lignocellulosic material and has the following properties: i) a particle size in the range of from 200 to 850 &mgr;m; ii) a pore volume of from 0.45 to 1.0 cm3 per gram; iii) a surface area in the range of from 800 to 1500 m2/g; and in that the binder is used in an amount not exceeding 25% by weight based upon the mixture of activated carbon and binder material.
