Title: Airway vent
Inventor: WEBB WALTER L
IPC: F24F13/065
Filed: 1999-03-01
Granted: 2005-12-06
Abstract: The present invention is a heating and cooling airway vent (12) that provides improved airflow directional control and is easier to manufacture, assemble, and install in building airway systems. The airway vent (12) includes a housing (14) having a number of fixed louvers (16) as well as a plurality of rotatable circular openings (18) in which circular inserts (20) are rotatably mounted. The circular inserts include curved louvers (22) that are angled with respect to the vertical and that are curved slightly outward. The circular inserts (20) can be rotated to direct their louvers (22), and hence the issuing air, in any desired direction. The circular inserts (20) are snap-locked into the housings (14). The vent (12) includes one or more dampers (26) operated by a damper switch (28). The damper switch (28) is connected to the housing using a guide slot (46) having ridges (48) that aid a user in keeping the damper switch (28) in a particular position. The vent housing (14), the circular inserts (20), and dampers (26) are all injection molded of a suitably rigid plastic.

Abstract: The present invention provides a method for preparing [F-18]-fluoride ion which comprises the step of bringing [O-18]-enriched water containing [F-18]-fluoride ion formed by proton irradiation of [O-18]-enriched water into contact with a strongly acidic cation exchange resin to remove impurity cations, the step of then bringing the [O-18]-enriched water contain-ing [F-18]-fluoride ion treated above into contact with a weakly basic anion exchange resin to make [F-18]-fluoride ion adsorbed to the resin and, along therewith, to recover the [O-18]-enriched water which has passed through the resin, and the step of eluting and collecting the [F-18]-fluoride ion adsorbed to the weakly basic anion exchange resin. According to the method for preparing [F-18]-fluoride ion of the present invention, [F-18]-fluoride ion can be collected at a high collection efficiency even from a larger amount (about 2 ml or more) of [O-18]-enriched water containing [F-18]-fluoride ion than the amount in prior method, and moreover expensive [O-18]-enriched water can be recovered and reused in the preparation of [F-18]-fluoride ion.

Title: Hydrocarbon conversion using large crystal zeolite catalyst
Inventor: SMITH ROBERT S
IPC: C07C2/66
Filed: 1997-10-17
Granted: 2008-08-26
Abstract: A process for converting hydrocarbons by contacting a hydrocarbon feedstream under hydrocarbon conversion conditions with a large crystal zeolite catalyst. The large crystal zeolite of the catalyst used in the hydrocarbon conversion process is made by heating an aqueous zeolite synthesis mixture under agitation to a temperature equal to or less than the effective nucleation temperature of the synthesis mixture. After this step, the aqueous synthesis mixture is heated in the absence of agitation to a temperature equal to or greater than the effective nucleation temperature of the aqueous zeolite synthesis mixture. The process finds particular application in hydrocarbon conversion processes where reduced non-selective acidity is important for reaction selectivity and/or the maintenance of catalyst activity, e.g., toluene disproportionation, dealkylation, alkylation, and transalkylation.

Abstract: A baled crop material processor for disintegrating baled crop material comprising a container, a disintegrator, a discharge opening and means for manipulating the crop material for disintegration by the disintegrator. The container, receives and contains the crop material. The disintegrator comprises a flail roller that is mounted within the container and has a number of flails pivotally mounted about it. The flail roller rotates about its own longitudinal axis in either a clockwise or counter-clockwise direction. The discharge opening is at the bottom of one of the side walls to discharge the disintegrated crop material either to the left or to the right of the processor and in a bidirectional processor, the operator may alternate between sides. The manipulation means comprises manipulator rollers having paddles positioned at an angle to the length of the roller to rotate the crop material without substantially breaking the crop material apart. The paddles are channel shaped with outwardly curved ends to grasp the baled crop material for rotation and then to pull out of the crop material due to the curved end as the roller is rotated. Further, the angled paddles guide the crop material longitudinally toward the centre of the crop material processor away from the front and back walls. Moreover, the sidewalk of the container are shaped to have a protrusion projecting into the container in close proximity to the paddles, a spacing below the protrusion to prevent the accumulation of loose material, and outwardly sloped wall portions above the protrusion.

Abstract: Method of producing liquefied natural gas (LNG) whereby refrigeration for cooling and liquefaction is provided by a mixed refrigerant system precooled by another refrigeration system. At least one liquid stream is derived from the partial condensation and separation of the mixed refrigerant at a temperature higher than the lowest temperature provided by the precooling system when the mixed refrigerant is condensed at a final highest pressure. When the mixed refrigerant is condensed at a pressure lower than the final highest pressure, condensation is effected at a temperatures equal to higher than the lowest temperature provided by the precooling system. The mixed refrigerant liquid is used to provide refrigeration at a temperature lower than that provided by the precooling system.

Abstract: Selective edge softening and selective edge dithering is introduced into an image representation to improve local control where halo problems are expected. Selective areas of dilation are isolated and separately dithered or halftoned, the result of which is then swapped back into or substituted for the stored original image. In this manner misregistration and color plane-to-plane interactions can be compensated for in plural image forming station architecture systems. The same technique is also valuable in monochrome systems as an aid to overcoming edge displacement and slow toner problems when the selective edge softening is selectively applied to edges which are in particular perpendicular to the fast scan direction.
