摘要： A skylight structure is formed with condensate channels at the upper portions of the purlins and rafters adjacent glazing panels supported by them. Preferably, the condensate channels and the means for interconnecting the purlin and rafters are concealed. The preferred structural members used as rafters and purlins have hollow closed tubular bodies.

摘要： A tine for a rotary spader which is intended for mounting on a horizontal drive shaft as one of a plurality of units spaced endto-end distinguished by a flat body, a set of four blades of dogleg shape presenting a sharpened leading edge and with each blade having a straight tip portion which is angled retreatingly to produce a swastika-like shape. The blades and body are formed integrally of a single plate of metal and each top portion is bent over at an angle along a bending line which is generally perpendicular to the tip axis, adjacent blades being bent in opposite directions.
摘要翻译：一种用于安装在水平驱动轴上的旋转式撑杆的齿，其作为由平坦主体区分开的端对端的多个单元之一，一组四条腿状的刀片呈现锋利的前缘并且每个叶片具有直的尖端部分，该直的尖端部分后退成角度以形成十字形。叶片和主体由单个金属板一体地形成，并且每个顶部沿着大体上垂直于尖端轴线的弯曲线以一定角度弯曲，相邻的叶片沿相反方向弯曲。

摘要： A control device for a heating unit in an electric range in the form of a low-power resistor and switch in a tubular capsule recessed in a convenient position near the unit. The capsule has a presented wall which is flexible so that a portion of the resistor therein may be shorted out to change the resistance value simply by pressing at a desired point along the length of the capsule. The capsule is sealed and contains a fluid so that when the capsule is pressed at a second point, for example, at the end of the capsule, pressure is developed resulting in release at the first point. The resistor is controllingly included in the input of a solid-state circuit having the heating unit in the output.
