Abstract: A seal (8) which is produced from an elastomer and comprises a contact plate (9) which rests against the outside of the housing and forms a sealing surface (10) surrounding an outlet orifice (12) is inserted into an orifice (7) at the lower end of a housing (2) of an ink cartridge (1). A ring (11) adjacent to the top of the contact plate (9) surrounds a passage connecting to the outlet orifice (12) and leading into the interior of the housing and carries an all-round collar (13) projecting over the edge of the orifice (7) on the inside of the housing, so that the seal (8) is snapped into the orifice (7). Once the ink cartridge (1) has been inserted into a receptacle (24) of an adapter (22), with which it forms an inkjet printing head, the sealing surface (10) presses against a frame which surrounds a receiving orifice (27) of the adapter (22), which receiving orifice is connected to a nozzle plate, so that the ink path is reliably sealed.

Abstract: A system that allows a team of geographically dispersed users to collaboratively analyze a mishap event. The system includes a reconfigurable ontology, including instances that are related to and characterize the mishap, a semantic network that receives, indexes and stores, for retrieval, viewing and editing, the instances and links between the instances, a network browser interface for retrieving and viewing screens that present the instances and links to other instances and that allow editing thereof, and a rule-based inference engine, including a collection of rules associated with establishment of links between the instances. A possible conclusion arising from analysis of the mishap event may be characterized as one or more of: not a credible conclusion; an unlikely conclusion; a credible conclusion; conclusion needs analysis; conclusion needs supporting data; conclusion proposed to be closed; and an un-reviewed conclusion.
