    • An improved electrically conductive light bulb base for use with common threaded light bulb sockets currently widely used. The improvement combines a substantial reduction in the amount of thread required, by employing a shorter thread that enlarges or increases in size, in radius, or both. This type of thread is in place of the standard thread in securing the bulb in the socket. Optionally, short portions of thread may be provided on one side of a generally cylindrical, smooth base. The particular advantage is that the bulb inserted by hand can be inserted and secured or released and removed with a minimum number of turns of the wrist.
    • 一种改进的导电灯泡底座,用于目前广泛使用的普通螺纹灯泡插座。 该改进结合了所需螺纹量的显着减少,通过采用放大或增加尺寸,半径或两者的较短螺纹。 这种螺纹代替将灯泡固定在插座中的标准螺纹。 可选地,短的螺纹部分可以设置在大致圆柱形的光滑基底的一侧上。 特别的优点是用手插入的灯泡可以用手腕的最小匝数插入和固定或释放和移除。

    • A method for trimming an undesirable portion of a metatarsal pad of a chicken paw using a power operated rotary knife. The steps of the method include: a) providing a power operated rotary knife including an annular knife blade rotatable about a central axis and defining a central open area; moving one of the rotary knife and the chicken paw with respect to the other to position the rotary knife with respect to a bottom of the chicken paw such that the undesirable portion of the metatarsal pad is within the central open area of the blade and the cutting edge of the blade is proximate to a periphery of the undesirable portion; and moving one of the rotary knife and the chicken paw such that the cutting edge of the blade slices a layer of the metatarsal pad thereby removing at least part of the undesirable portion.
    • 一种使用动力操作的旋转刀来修剪鸡爪的跖骨垫的不希望的部分的方法。 该方法的步骤包括:a)提供动力操作的旋转刀,其包括可围绕中心轴线旋转并限定中心开放区域的环形刀片; 将旋转刀和鸡爪中的一个相对于另一个移动,以相对于鸡爪的底部定位旋转刀,使得跖骨垫的不希望的部分在叶片的中央开口区域内并且切割 叶片的边缘接近不期望部分的周边; 以及移动所述旋转刀和所述鸡爪中的一个,使得所述刀片的切割刃切割所述跖骨垫的一层,从而移除所述不期望部分的至少一部分。
