    • A window drain for preventing stains on a building wall and damage caused by frozen rain water, which is installable and sealable easily without impairing the appearance of a building. The present invention relates to a window drain adapted to be positioned at the portion beneath each vertical post of a sash window frame comprising a vertical portion, a sloping portion, a front portion and a horizontal portion for latching itself to an upper portion of an external wall. Further, the present invention relates to the window drain, wherein the horizontal portion has a notch at an end thereof and a sealing pocket. Further, the present invention relates to a window drain, further comprising upstanding portions to regulate a stream of water so that the water is kept between the upstanding portions, at both ends of the window drain wherein one upstanding portion is located at the inner side of the vertical portion of a sash window frame, and the other upstanding portion is located at the outer side of the vertical portion of a sash window frame.
    • 用于防止建筑物墙壁上的污渍和易受冻雨造成的破坏的窗户,易于安装和密封,而不会损坏建筑物的外观。 本发明涉及一种适于定位在窗框框架的每个垂直柱下方的部分处的窗口排水口,其包括垂直部分,倾斜部分,前部分和水平部分,用于将其自身锁定到外部的上部 壁。 此外,本发明涉及窗口排水,其中水平部分在其一端具有凹口和密封袋。 此外,本发明涉及一种窗排水装置,其还包括直立部分以调节水流,使得水保持在直立部分之间,在窗口排水的两端处,其中一个直立部分位于 窗框框架的垂直部分,另一直立部分位于窗框框架的垂直部分的外侧。

    • A method of inspecting storage tanks for leaks by means of pressure decrease and increase in the tanks, in which a part of a liquid 6 stored in a tank 1 is discharged to put the tank 1 under vacuum and variations in the pressure in the tank 1 with time are checked, the pressure in the tank 1 is thereafter increased to the level of the atmospheric pressure, and then the liquid which was discharged from the tank is poured back thereinto to put the tank under pressure and variations in the pressure in the tank with time are checked. The method is done by an apparatus designed for inspecting storage tanks for leaks by means of pressure decrease and increase in the tanks, having an air pipe (2), a measuring pipe (3), a liquid feed pipe (4), a liquid suction pipe (5) and an air-tight container (7), which are communicated with a tank (1) to be inspected, a pressure regulator pump (8) connected to the air-tight container (7), and a manometer (11) and a recording air gauge (10) connected to the measuring pipe (3).
