Abstract: A tobacco tablet that includes a solid solution of soluble fiber and one or more sugar alcohols, the solid solution having a glass transition temperature of less than 40° C., and tobacco dispersed in the solid solution such that the tobacco is released from the tablet when the tablet is chewed or dissolved within an oral cavity.

Abstract: A tobacco lozenge includes a body configured to be wholly receivable in an oral cavity. The body includes a matrix including a soluble fiber in an amount greater than or equal to 60 weight percent of the body, tobacco plant tissue dispersed in the matrix, and an additive dispersed in the matrix.

Abstract: A nozzle/valve device for a ducted rocket motor is provided. The nozzle/valve device employs a design in which a nozzle throat blockage element can be moved by translational motion within the nozzle throat section of the device. The blockage element is designed so that in the closed position the nozzle throat has a minimum cross-sectional flow area and therefore the nozzle throat is never fully closed. The seals employed in the nozzle/valve device are isolated from contact with reaction products of the gas generator and effective use of minimum amounts of erosion resistant materials is achieved.

Abstract: A nozzle/valve device for a ducted rocket motor is provided. The nozzle/valve device employs a design in which a nozzle throat blockage element can be moved by rotational motion into and out of the nozzle throat section of the device. The blockage element is designed so that in the closed position the nozzle throat has a minimum cross-sectional flow area and therefore the nozzle throat is never fully closed. The seals employed in the nozzle/valve device are isolated from contact with reaction products of the gas generator and effective use of minimum amounts of erosion resistant materials is achieved.

Abstract: A ramjet, swing disc, variable nozzle structure with corrosive resistant, coated graphite inserts positioned within oppositely disposed recesses in the swing disc structure.

Abstract: This device is essentially a butterfly type valve which acts as a flow constriction by rotating a disc body with its planar axis parallel to or at right angles to fluid flow through a channel. The disc body has an additional capability of extending sectors from the body beyond the original boundary or peripheral edge of the body, thereby increasing the restriction of the flow area surrounding the disc.
