Abstract: A distributed control system (DCS) of an industrial process plant includes a data center storing a plant information model that includes a description of physical components, the control framework, and the control network of the plant using a modeling language. A set of exposed APIs provides DCS applications access to the model, and to an optional generic framework of the data center which stores basic structures and functions from which the DCS may automatically generate other structures and functions to populate the model and to automatically create various applications and routines utilized during run-time operations of the DCS and plant. Upon initialization, the DCS may automatically sense the I/O types of its interface ports, detect communicatively connected physical components within the plant, and automatically populate the plant information model accordingly. The DCS may optionally automatically generate related control routines and/or I/O data delivery mechanisms, HMI routines, and the like.

Abstract: A long range artillery shell (1) comprising rocket propellant material (10), a rocket motor nozzle (14) and base bleed propellant material (12). Ignition of the rocket propellant material (10) is delayed until the base bleed propellant material (12) has substantially finished burning. The base bleed propellant material (12) may be housed in the same chamber and behind the rocket propellant material (10) in order to provide support to the rocket propellant material (10) during launch. The two propellant materials (10, 12) may be separated by a thermal ignition barrier (18) to prevent premature rocket ignition.

Abstract: A multi-segment seal ring for rotary equipment of the type involving a relatively large-diameter rotary cylinder supported with its axis horizontal by one or more fixed housings, seals being employed between the cylinder and at least one of the housings. One problem in equipment of this type is the practical impossibility of manufacturing and maintaining the cylinder as a perfect cylinder and special sealing structures are typically employed to accommodate out-of-round conditions of the cylinder, an example of which forms the subject matter of copending U.S. application, Ser. No. 618,984, filed June 8, 1984, now U.S. Pat. No. 4,502,702. The present invention provides improvements in the configuration and sealing of the gaps that occur at the overlapping, radial interfaces between neighboring segments, particularly to the end of increasing the efficiency of the equipment by eliminating or at least minimizing packing of treated material in the gaps.

Abstract: A seal assembly for effecting a seal between a stationary housing and a rotatable cylinder includes a plurality of arcuate segments radially disposed about the outer circumference of the cylinder. Each segment has an axial sealing surface defining a radius approximately equal to that of the rotatable cylinder and additionally has an end section for overlapping adjacent segments thus creating a gap and radial interface between the adjacent circumferentially disposed segments. The sealing assembly additionally comprises means for sealing the gaps formed by the adjacent overlapping segments, apparatus for tensioning the segments radially about the outside circumference of the cylinder and studs for removably attaching each segment to the housing while concurrently permitting radial displacement of each segment independently from its adjacent segments.
