Abstract: An automated activity-based management system and method (10) for making thereof are provided. A business organization has costs associated with its employees, facilities, equipment, and overhead to produce products or provide services. Such a business organization typically generates traditional general ledger accounting information (152) and human resources information (150). This traditional accounting information (150, 152, 154) is used along with information directed to activities, equipment usage and facilities utilization to generate costs associated with activities performed by the organization. A computer workstation (40) with a graphical user interface (42) is used to accept entries of activity information (74). The activity information and traditional accounting information are fed to a relational database (12). The information is processed and costs associated with the employee, facilities, equipment, and overhead components (20, 22, 24, 26) of activities are computed.

Abstract: A substance delivery and filter system for use in delivering or conveying a dry, fluid powder substance from a closed container to an open receptacle is provided. The delivery and filter system includes a filter housing having a heavy particle cyclone separator, a fine particle filter bag assembly, a substance inlet port positioned just above the heavy particle cyclone separator, a substance outlet port positioned at the bottom of the cyclone separator, and a filtered air outlet port communicating between the clean side of the filter bag assembly and the outside environment. The powder substance in the container is entrained in an air stream and introduced into the filter housing through a conduit connected to the substance inlet port. The heavier substance particles fall downwardly from the swirling air stream caused by the cyclone separator and are discharged into an open-air receptacle from the substance outlet port.

Abstract: A device which permits the conveyance of a dry fluid substance from one receptacle to another without the release of a significant amount of dust into the surrounding atmosphere is provided. The device is a housing with an interior volume divided into two sections and having an access opening and a discharge opening. A dry fluid substance is introduced into the device and into an inner chamber within the interior volume of the device which guides the substance from the access opening to the discharge opening and causes the separation of particulate matter from the substance. The particulate matter dispersed from the substance is drawn by a vacuum applied to the housing from the inner chamber into the filter chamber where the particulate matter is retained on a plurality of fine filter bag assemblies.

Abstract: A device which permits the conveyance of a dry fluid substance from one receptacle to another without the release of a significant amount of dust into the surrounding atmosphere is provided. The device is a housing with an interior volume divided into two sections and having an access opening and a discharge opening. A dry fluid substance is introduced into the device and impinges against an orifice wall having a plurality of orifices therethrough, each sized to slow conveyance of the substance through the housing. The contact with the orifice wall causes the separation of fine particulate matter from the substance. The fine particulate matter dispersed from the substance is drawn by a negative pressure applied to the housing from the inner chamber into the filter chamber where the particulate matter is retained on a plurality of fine filter bag assemblies.

Abstract: A filter system that is portable and has no moving parts usable for industrial purposes to filter dry fluid substances such as Barite, Hemitite, cement and the like. Within a filter housing are a cyclone separator for removing heavier substance and a fine filter for filtering lighter powdery substance. The inlet to the housing is connectable to the vent of a storage receptacle to which substance is being transferred under the power of a blower. The blower creates the stream that causes substance to flow through the filter system so that no other power means is required. To purge the filter system, a normally capped outlet is connected directly to the storage receptacle and a vent port from the filter housing is connected directly to the blower means. The blower means is operated in spurts to create bursts of air in a direction opposite to the filtering direction to dislodge powder from the fine filter and blow the powder and heavier particles from the filter housing directly into the storage receptacle.
