    • A tree trimming apparatus may include a first frame portion and a second frame portion that are spaced apart from each other. Each frame portion may have a generally circular shape so that the entire frame of the apparatus may be positioned around the trunk of a tree. A vertical actuator connects the first and second frame portions and may operate to increase or decrease the distance between those portions. Further, a horizontal actuator may be positioned on each of the portions with each horizontal actuator operating to extend into the interior of each frame portion and engage a tree trunk. Additionally, a cutting device may be positioned on the first frame portion to assist in the cutting or trimming of the tree.
    • 树修剪装置可以包括彼此间隔开的第一框架部分和第二框架部分。 每个框架部分可以具有大致圆形的形状,使得装置的整个框架可以位于树的树干周围。 垂直致动器连接第一和第二框架部分,并且可以操作以增加或减小这些部分之间的距离。 此外,水平致动器可以定位在每个部分上,每个水平致动器操作以延伸到每个框架部分的内部并且接合树干。 另外,切割装置可以被定位在第一框架部分上以辅助切割或修剪树。

    • An air conditioning unit with a protective cap for preventing the intrusion of sun, rain, snow, debris, and the like, into an updraft fan housing and an area proximate heat exchange coils is disclosed. The cap comprises a cap member and a hinge member having a first and second a side. A shoulder member enables a secure attachment of the cap member to the second side of the hinge member. The second side of the hinge member is securely attached to the shoulder member to enable the cap member to pivot relative the first side of the hinge member. The first side of the hinge member is securely attached to the air conditioning unit proximate the exhaust opening of the air conditioning unit to enable the cap member to pivot open upon activation of the updraft fan moving ambient air out of the exhaust opening and to pivot to a closed position upon deactivation of the updraft fan causing the movement of the ambient air to stop. The cap prevents the intrusion of the debris, rain, snow and sun into the exhaust opening of the air conditioning unit during the deactivation of the updraft fan and deflects sound generated by the updraft fan during the activation of the updraft fan.
    • 公开了一种具有用于防止太阳,雨,雪,碎屑等入侵的保护盖的空调单元进入上升气流风扇壳体和靠近热交换盘管的区域。 盖包括盖构件和具有第一和第二侧的铰链构件。 肩部构件能够将盖构件牢固地附接到铰链构件的第二侧。 铰链构件的第二侧牢固地附接到肩部构件,以使盖构件相对于铰链构件的第一侧枢转。 铰链构件的第一侧在靠近空气调节单元的排气口处紧密地附接到空气调节单元,以使得盖构件能够在上升气流风扇启动时将环境空气从排气口移出并枢转到 在上升气流风扇停用时,关闭位置使得环境空气的运动停止。 在上升气流风扇停用期间,盖子防止碎片,雨,雪和太阳侵入空调单元的排气口,并在上升气流风扇的启动期间偏转由上升气流风扇产生的声音。
