    • An air duct comprises a duct wall bounding an airflow channel that extends through the air duct along a flow path. The airflow channel has a plurality of cross-sections that are bounded by the duct wall and that are perpendicular to the flow path. A first one of the cross-sections has an aspect ratio that is less than two. A second one of the cross-sections has an aspect ratio that is greater than four and a minimum dimension that is less than three-quarters of an inch. A third one of the cross-sections has an aspect ratio that is less than two. The second cross-section is positioned between the first and third cross-sections along the flow path. The air duct channels air beneath a door, thereby allowing a vacuum or blower tool to operate in one room while the vacuum or blower device operating the tool operates in a different room.
    • 空气管道包括一个管道壁,该管道壁沿着一个流动通道延伸穿过空气管道。 气流通道具有由管道壁限定并且垂直于流动路径的多个横截面。 横截面中的第一个具有小于2的宽高比。 横截面中的第二个横截面的长宽比大于4,最小尺寸小于四分之三英寸。 横截面中的第三个宽高比小于2。 第二横截面位于沿着流动路径的第一和第三横截面之间。 空气管道在门下方通风,从而允许真空或鼓风机工具在一个房间中操作,而操作该工具的真空或鼓风机装置在不同的房间中操作。

    • A pet grooming tool, for use with a furry pet such as a dog or cat having loose hair and non-loose hair, is adapted for removing the loose hair from the pet. The grooming tool comprises an elongate handle portion extending generally along a handle axis, and a pet engageable portion secured to the handle portion. The pet engageable portion includes a blade portion and a plurality of teeth. The blade portion includes a blade edge. The teeth extend from the blade edge. The pet engageable portion is secured to the handle portion in a manner so that pulling the handle portion generally along the handle axis while the pet engageable portion is in engagement with the pet causes the blade portion to engage the loose hair of the pet and pull it from the pet without cutting or pulling the non-loose hair from the pet.
    • 宠物美容工具,用于与毛发宠物如具有松散头发和非松散头发的狗或猫一起使用,适于从宠物中去除松散的头发。 整修工具包括大致沿着手柄轴线延伸的细长把手部分和固定到把手部分的宠物可接合部分。 宠物可接合部分包括刀片部分和多个齿。 叶片部分包括叶片边缘。 齿从叶片边缘延伸。 宠物可接合部分以这样的方式固定到手柄部分,使得当宠物可接合部分与宠物接合时,大致沿着手柄轴线拉动手柄部分,使得刀片部分接合宠物的松散头发并将其拉动 从宠物没有切割或从宠物拉起非松散的头发。
