    • An oscillating hair dryer nozzle assembly attaches to a hand held electric hair dryer. An oscillating nozzle is pivoted back and forth by forced air generated by an electric motorized fan within the hair dryer. A propeller receives the forced air and rotates a propeller shaft which is coupled to a gear reduction assembly. The gear reduction assembly converts the rotational motion of the propeller shaft into repetitive pivotal movement of the oscillating nozzle. The oscillating nozzle automatically redirects the air flow in a plane. In one embodiment, the nozzle assembly is rotatably attached to the output barrel of a hair dryer body so that the oscillating nozzle can be rotated to pivot and redirect air flow in a different plane.
    • 旋转式吹风机喷嘴组件连接到手持式电吹风机上。 振动喷嘴通过吹风机内的电动风扇产生的强制空气来回摆动。 螺旋桨接收强制空气并旋转传动轴,其连接到齿轮减速组件。 齿轮减速组件将传动轴的旋转运动转换成摆动喷嘴的重复枢转运动。 摆动喷嘴自动重新定向一个平面上的气流。 在一个实施例中,喷嘴组件可旋转地附接到吹风机主体的输出筒,使得摆动喷嘴可以旋转以枢转并在不同的平面中重定向空气流。

    • A pencil has a fixed non-replaceable eraser and a moveable sleeve. The fixed non-replaceable eraser is elongated to provide a larger eraser to pencil ratio in order to have more erase cycles per write cycles. The moveable sleeve can be moved to selectively expose a portion of the eraser. A ferrule couples the pencil body and the eraser together and provides an outer surface to engage an inner surface of the moveable sleeve. In one embodiment, a threaded female slot in the outer surface of the ferrule engages a male threaded tab in the inner surface of the sleeve. In another embodiment, a plurality of concentric slots in the outer surface of the ferrule engage a tab in the inner surface of the sleeve.
    • 铅笔有固定的不可更换的橡皮擦和可动的袖子。 固定的不可更换的擦除器是细长的,以提供更大的橡皮擦到铅笔比率,以便在每个写周期具有更多的擦除周期。 可移动的套筒可以移动以选择性地暴露橡皮擦的一部分。 套管将铅笔主体和橡皮擦结合在一起并提供外表面以与可移动套筒的内表面接合。 在一个实施例中,套圈的外表面中的螺纹凹槽与套筒内表面中的阳螺纹接头接合。 在另一个实施例中,套圈的外表面中的多个同心槽与套筒的内表面中的接头接合。
