摘要:
The present invention provides a process for preparing carbocyclic or heterocyclic nitrites by the vapor phase contact ammoxidation of carbocyclic compounds or heterocyclic compounds, in which the reaction is carried out effectively without the increase of the amount of ammonia or oxygen used or the introduction of steam to give the nitrites as the objective products stably with the passage of time in a high yield with a high selectivity. A process for preparing carbocyclic or heterocyclic nitrites comprising subjecting the corresponding starting carbocyclic or heterocyclic compounds to ammoxidation via the vapor phase catalytic reaction in a fluidized bed reactor, in which the reaction is carried out in the presence of a metal oxide fluidized bed catalyst containing vanadium and/or molybdenum as the catalyst, oxygen-containing gas being supplied through an oxygen-containing gas inlet provided at the bottom of the fluidized bed reactor, the starting cyclic compound and ammonia being supplied at a level higher than the oxygen-containing gas inlet, a fluidized bed being formed so that the ratio of the amount of catalyst (Wb) fluidized at a level higher than the inlet of the starting cyclic compound to the amount of catalyst (Wa) fluidized at a level higher than the oxygen-containing gas inlet in the reaction zone is in the range of Wb/Wa=0.01-0.95 by weight.

摘要:
A managing computer adds a bulk-sales negotiation ID to a bulk-sales negotiation to distinguish the bulk sales negotiation from a normal sales negotiation. An amount of scheduled shipment and completed shipment for the bulk sales negotiation is managed by a bulk-sales-negotiation managing unit based on the bulk-sales negotiation ID. The managing computer obtains an amount of completed shipment of a regular negotiation by subtracting an amount of completed shipment of the bulk-sales negotiation from a total amount of completed shipment. The managing computer calculates a seasonal index based on an amount of completed shipment according to a stratification of products to design a sales plan. The managing computer adds an amount of schedule shipments of the bulk sales negotiation to the sales plan.

The present invention is an Emergency Response Center (ERC) which provides a variety of emergency and information functions in public environments. The ERC operates in a number of modes, including Information Mode, Emergency Response Mode, Security Mode, and Surveillance Mode. The Emergency Response Center functions are software selectable on a large video touch screen. A video screen displays emergency information to users and allows videoconferencing with various authorities as well as any individuals that own the account and apparatus. News, maps, weather, store directories, and other non-emergency information are also displayed by the ERC. The ERC can conduct surveillance of passersby using video cameras configured to stream and record the area in the vicinity of the ERC. The ERC can also scan employee IDs, capture employee facial images, and register employee data in the ERC database. An ERC server allows remote administration of the ERC.

摘要:
The present invention is a reverse vending machine which accepts non-metallic and metallic beverage containers for processing. The beverage containers are inserted by the user into an intake chute, where they are then compacted, sorted, and deposited in storage bins contained in the machine. A number of additional functions are provided by the reverse vending machine, including a self cleaning system, a video screen for displaying information to users, a bar code scanner for scanning bar codes, a user ID reader, and a coupon printer for issuing coupons to users. All transaction information is processed by a computer and stored electronically. The invention automatically returns non-empty containers and containers with unacceptable or unreadable bar codes to the user. The user is also provided warning messages when the storage bins are nearly full, or when a container is jammed in the machine.
