摘要： AN IMPLEMENT FOR CUTTING INIFORM SHORT LENGTHS OF YARN FROM A STRIP OF MATERIAL OR YARN SKEIN FOR USE IN MAKING HOOKED RUGS IS DISCLOSED. ROTATION OF A MEMBER CAUSES YARN TO BE FED OVER A CHANNELED SURFACE BENEATH AN OSCILLATING BLADE IN THE ROTATING MEMBER AND CUT OFF AT A PREDETERMINED POINT IN EACH ROTATION. THE LENGTH OF THE CUT OFF PIECES MAY BE ALTERED BY INSERTION OR REMOVAL OF A COLLAR AT THE HUB OF THE ROTATING MEMBER

摘要： A solar energy collector includes a housing having a cover transparent to solar energy. A solar energy absorber is enclosed within the housing just beneath the cover. The absorber is formed to define a plurality of narrow fluid channels of triangular cross section which are disposed in close proximity to each other. The triangular cross section fluid channels are defined by a serpentine-shaped metal top sheet which is secured to a flat metallic bottom sheet. The upper ridges of the fluid channels are disposed in proximity to and support the cover. The geometric relation between the fluid channels, the narrow air spaces defined between the fluid channels and the cover is such as to provide a low cost, high efficiency panel.
摘要翻译：太阳能收集器包括具有对太阳能透明的盖的壳体。一个太阳能吸收器被封闭在壳体正下方的盖子之下。吸收器被形成为限定了彼此紧密配置的多个三角形横截面的窄流体通道。三角形横截面流体通道由固定在平坦的金属底片上的蛇形金属顶片限定。流体通道的上脊设置在盖子附近并支撑盖子。流体通道之间的几何关系，流体通道和盖子之间限定的狭窄的空气空间是提供低成本，高效率的面板。
