  • Patent number: 4569617
    Abstract: The invention relates to a pile construction comprising a number of steel tube sections (1) that are joined together. Each tube section (1) is formed with joining portions (2, 4) in its respective ends. One joining portion is constituted by a male end (2) having a conical envelope surface (3) and the other portion by a socket end (4), the interior surface (5) of which is conical in correspondence to the conicity of the male end (2). When the tube sections (1) are joined the male end (2) of one section interacts with the socket end (4) of the next section, so that a stiff joint is obtained.

  • Patent number: 4480655
    Abstract: A liquid-plug-creating device includes a collection tank or basin into which liquid flows such as the outflow from sanitary appliances. From the outlet at the bottom of the tank a riser extends upwardly at an acute angle to the horizontal. At the opposite end from the tank outlet, the riser terminates in a bend which reverses the direction of flow through the riser into a downwardly extending vertical pipe. A U-shaped piece of pipe with a horizontal outlet is connected to the lower end of the vertical pipe and provides a special form of trap. When the tank and the riser are completely filled with liquid, any additional liquid added exceeding a minimum flow, causes a liquid seal to be formed in the piece of pipe at the lower end of the vertical pipe. The excess flow creates a vacuum in the vertical pipe which sucks the liquid through the riser out of the tank in the manner of a siphon. The liquid immerges from the device in the form of continuous plugs with high kinetic energy content.
