摘要： An eavestrough system comprises a particular eavestrough section having inwardly directed locking flanges adjacent opposed upper edges thereof. This eavestrough section is designed to cooperate with a hidden hook having a cored base portion which cooperates with a cantilevered arm whick supports the eavestrough at the free end thereof. A downwardly opening locking slot is provided at the junction of the arm and base.

摘要： A steel hot water tank having a corrosion inhibiting coating on the interior surfaces of the tank is provided with end portions each having concave interior surfaces. A connecting device is used to permit connection of a precoated tank end to a precoated tank interior whereby the heat of welding the tank end to the tank side wall does not degrade the corrosion inhibiting coating of the tank interior. This construction provides increased volume for the tank compared to existing hot water tank constructions, and enables the use of material thicknesses in the tank ends which may be equal to or less than the material thicknesses of the tank side wall. A process is provided which permits the welding of the tank end to the tank side wall without degrading the corrosion inhibiting coatings previously applied to the parts being assembled.
摘要翻译： 在罐的内表面上具有防腐蚀涂层的钢热水箱具有各自具有凹形内表面的端部。 连接装置用于允许将预涂覆的罐端连接到预涂的罐内部，由此将罐端焊接到罐侧壁的热量不会降低罐内部的腐蚀抑制涂层。 与现有的热水箱结构相比，这种结构提高了罐的体积，并且能够使用罐端部中的材料厚度等于或小于罐侧壁的材料厚度。 提供了一种方法，其允许罐端部焊接到罐侧壁，而不会降低先前施加到正在组装的部件上的防腐蚀涂层。
