Abstract: An apparatus and process is provided for the removal of hydrogen sulfide from gases and for restoration of hydrogen sulfide removal capacity in nitrogen-treated carbonaceous chars which have become exhausted for hydrogen sulfide capacity when used for the removal of hydrogen sulfide from gas streams. The apparatus has a matrix of removable canisters which contain the nitrogen-treated carbonaceous chars.      This process entails directing the gas containing hydrogen sulfide through the canister, washing the spent carbonaceous char with water by flushing/ dynamic washing through the canister to remove the majority of the hydrogen sulfide reaction products. By the use of this process a significant proportion of the original hydrogen sulfide capacity of the nitrogen-treated carbonaceous char is recovered and the canisters can be recycled a large number of times.

Abstract: Selection of a call-center agent (106-108) to handle a call is based on which available agent's handling of the call will tend to optimize call-center performance criteria such as efficiency (e.g., minimize per-call handling time) or derived benefit (e.g., maximize revenue). Each agent has a service profile for each type of call that they handle. A service profile (400-402) comprises present values of a plurality of service metrics, such as proficiency, profitability, customer satisfaction, and agent satisfaction. When a call of a particular type becomes available, the present values of the service metrics of the service profile (400-500) of that call type of each agent who is available to handle the call are combined (304) into a score according to one of a plurality of formulas which corresponds to that call type, and the agent with the best score is assigned (306) to the call. When the assigned agent finishes handling the call, his or her performance is evaluated (202-206) based on the service metrics, and the valuations are used (210) to revise the present values of the service metrics of that agent's service profile. The revision process gives (208) more weight to valuations of more-recently-handled calls to reflect both long-term and short-term agent performance trends and variations.

Abstract: The invention concerns a tracheal tube (1) that closes the trachea liquid-tight, comprising a cuff (5) blocking the trachea below the glottis and through which a respiration cannula (1) is passed. A tampon vesicle (7) made out of flexible material which expands as fluid flows through is cranially placed above the cuff. When filled, said vesicle differs in shape from that of the cuff. This tracheal tube must be improved so that a patient can be intubated for a long period of time with the minimum of suffering and with a reduced risk of infection. According to the invention, this is accomplished by the fact that the tampon vesicle (7) once filled rests directly on the cuff (5), the tampon vesicle is made out of a foil-like material and its filled size is designed to fill the subglottic region.

Abstract: A pressure relief valve such as is used to relieve over-pressure in the passenger compartment of an automotive vehicle has valve flaps which are retained in connection with a housing by molded-in-place retainer strips. The valve is manufactured by an injection molding tool having a pair of mold halves defining a first mold cavity for forming the housing and a second mold cavity for forming the flaps. After the housing and flaps have set, the mold is opened, with the housing remaining in contact with one mold half and the flaps remaining in contact with the other mold half. One mold half is then moved relative to the other to place the housing and the flaps in alignment with one another, and the mold halves are closed again to place the flaps inside the housing and define a third mold cavity extending along the lines of desired attachment between the flaps and the valve seats. A third quantity of thermoplastic material is injected into the third mold cavity where it sets to form the retainer strips, bonding with the edges of the flap and the adjacent edges of the valve seat. The third mold cavity also extends around a peripheral flange surrounding the housing, forming a seal which is bonded to the housing. The part is complete when ejected from the mold, with no additional assembly required.

Title: Hierarchical data storage system and data caching method
Inventor: ABE TSUYOSHI
IPC: G06F12/08
Filed: 1999-08-06
Granted: 2001-12-11
Abstract: In a hierarchical data storage system that supplies data, on request, from a library apparatus in which the data are stored on removable media and from a high-speed cache device, the requests are analyzed to select the most frequently requested data and predict the system's least busy periods. During each predicted least busy period, data are copied from the library apparatus to the cache device, if necessary, so that all of the selected most-frequently-requested data are stored in the cache device. Data are not transferred from the library apparatus to the cache device at other times, thereby avoiding unnecessary cache replacements and improving the efficiency with which requests can be served.

Abstract: The object of the present invention is to provide a blade for a combined cycle gas turbine that can be effectively cooled with a proper amount of steam.      The blade for the gas turbine according to the present invention includes an internally formed coolant steam passage (a) for cooling the blade with coolant steam flowing through the coolant steam passage (a), and is characterized in that this ratio (t/c) of blade thickness (t) of the gas turbine blade to chord length (c) thereof is not greater than 0.15.      Assuming that the flow rate of the coolant steam flowing through the coolant steam passage (a) is constant, the flow speed of the coolant steam increases as the ratio (t/c) becomes smaller.      Further, the heat transfer rate at an inner wall surface portion of the blade similarly increases. Accordingly, by selecting the ratio (t/c) to be not greater than 0.15, which corresponds to a minimum heat transfer coefficient (a1) demanded in view of the cooling performance of the gas turbine blade, not only can the gas turbine blade be effectively cooled but a low steam flow rate appropriate for the combined cycle can also be sustained. In particular, the ratio (t/c) should fall within a range of 0.10 to 0.15 in order to realize effective reutilization of the recovered coolant steam.
