    • A foam-filled cap sealing ink-ejecting nozzles of an inkjet printhead in a printing mechanism has a two-layer structure, with an outer skin layer of an elastomer, and a second foam core layer inside the skin. The skin defines a sealing lip that surrounds the nozzles when the cap is in a sealing position to avoid unnecessary drying of the ink. The skin has an interior surface that defines a cavity under the sealing lip. The foam core, located within the cavity, may be formed by expanding a foam preform or by injecting raw foam into the cavity. An insert may be molded into the cap structure for use in mounting the cap in the printing mechanism. An optional backing layer molded to the structure is used to attach a vent basin to the cap. A method of constructing this cap, and a printing mechanism having this cap, are also described.
    • 打印机构中的喷墨打印头的泡沫填充盖密封喷墨喷嘴具有双层结构,弹性体的外表皮层和皮肤内部的第二泡沫芯层。 当帽处于密封位置时,皮肤限定围绕喷嘴的密封唇,以避免墨水的不必要的干燥。 皮肤具有限定在密封唇下方的空腔的内表面。 位于空腔内的泡沫芯可以通过将泡沫预制件膨胀或通过将原始泡沫注入空腔来形成。 插入件可以模制到盖结构中,用于将盖安装在打印机构中。 使用模制到该结构的任选的背衬层将排气孔附接到盖上。 还描述了构造该盖的方法和具有该盖的打印机构。

    • A structural joint system connects hollow structural members that provide load transfer and alignment for the connection between structural members is described. The structural members may comprise a plurality of beams each having a first and second structural members. A first and second members being joined may or may not be axially aligned.In some embodiments, the structural joint includes a first structural member having a first mating face at one end of the first structural member, the first mating face having a two dimensional profile, a second structural member having a second mating face at one end of the second structural member and positioned proximate to the first mating face of the first structural member, the second mating face having a two dimensional profile that is similar to the two dimensional profile of the first mating face, a splice plate secured to the first structural member at the first mating face and removably secured to the second structural member at the second mating face, and fasteners that secure the splice plate to the first structural member and removably attach the splice plate to the second structural member.
