Title: Projectile retardation system
Inventor: WEBB GLENN EDWARD MARTIN
IPC: F42B10/14
Filed: 1989-10-24
Abstract: A retardation system for use on a projectile launched from an aircraft absorbs the retardation forces, with minimal inertial loss, arms the fuze and erects the fins. A parachute or balloon is attached via lines 3 to an arming cylinder 4, the force on the lines causing the cylinder to slide rearwardly relative to the projectile. This movement causes (i) portion 7 of the cylinder 4 to compress a damper 8 via an arm 10, thus damping launch forces; (ii) lines 16 to erect the fins; and (iii) a ballscrew 11 and a shaft 14 to be screwed into a position to arm the fuze. <IMAGE>

Title: Absorbent sheets for cleaning and absorbing ink from ink-jet printheads
Inventor: DEMARCHI MICHAEL E
IPC: B41J2/165
Filed: 1990-10-29
Abstract: An absorbent sheet is passed through the paper-feed of an ink-jet printer to clean and absorb ink from the print-head at the printing station. As described, such a sheet is employed during start-up routines (to absorb ink ejected during purge of the nozzles). The thickness of the sheet is such as will ensure contact with the nozzles at the printing station (while not being too thick to be transmitted by the paper feeding mechanism) so that wiping of the nozzles takes place as the sheet is transported past the printhead. As described (Fig 3) a backing (paper) (32) has adhered thereto by an adhesive (40) a plurality of strips of absorbent foam (36) which are overlaid by fabric (clean-room lint free fabric) (38). The sheet may bear distinguishing indicia which may be read by a sensor on the printer. <IMAGE>
