  • Patent number: 11987052
    Abstract: A nozzle plate of a fluid ejection head for a fluid ejection device, a fluid ejection head containing the nozzle plate, and a method for making the fluid ejection head containing the nozzle plate. The nozzle plate includes at least two arrays of nozzle holes on opposing sides of a fluid supply via etched in an ejection head substrate and a photoresist layer attached to an exposed surface of the nozzle plate spanning a section of the nozzle plate between the at least two arrays of nozzle holes. The photoresist layer increases a thickness of the nozzle plate between the at least two arrays of nozzle holes to greater than 25 microns up to about 100 microns.

  • Patent number: 5627340
    Abstract: A plastic floor box assembly for use with electrical raceways installed in concrete floors, having a plastic box, an activation ring, a cover plate for retaining an electrical outlet, and an outlet cover securable to the cover plate. The activation ring is secured within the open top of the floor box by a plurality of retaining clips, having barbs extending outwardly and upwardly therefrom. The barbs allow easy insertion of the activation ring into the box, while preventing withdrawal. In a second embodiment designed for use in tile floors, a pair of support clips are also provided on the activation ring to prevent over-insertion of the ring into the box.

  • Patent number: 4575876
    Abstract: This invention involves a coat with a built-in-sleeping bag. The sleeping bag is attached to an ordinary jacket in place of the back coat lining. When not in use, the sleeping bag is folded inconspicuously inside the back of the coat. When the need arises, the bag may be unfolded and used as a conventional sleeping bag or as a coat-sleeping bag combination whereby the coat's sleeves are used in a normal fashion.
