Abstract: Embodiments of an ultra-fine-grained, medium carbon steel are disclosed herein. In some embodiments, the ultra-fine grained steel can have high corrosion fatigue resistance, as well as high toughness and yield strength. The ultra-fine grained steels can be advantageous for use as sucker rods in oil wells having corrosive environments.

Abstract: The invention relates to a container arrangement for fluids that contain gas, comprising a casing. Said casing is made of a pressure-proof collapsible material, and surrounds at least two chambers. The first chamber is used to receive and release the fluids containing gas via a first connection. The second chamber is a pressure chamber that is provided with a second connection for applying pressure. A flexible wall is arranged between the first chamber and the second chamber. The invention further relates to a method for transporting and releasing liquids containing gas into or from a pressure-proof collapsible casing, in addition to a corresponding pressure-proof, flexible non or slightly elastic covering. A container arrangement for liquids containing gas that has a simple construction, is easy to produce, fill, transport, empty and dispose of or recycle is provided due to the above mentioned invention.

Abstract: Disclosed is a table with a table top which is connected via a table leg to a pedestal which can be placed on the ground. Between the table top and the pedestal is arranged a swivel joint, by means of which the table top is pivotable relative to the pedestal about at least one swivel axis aligned perpendicular to the lengthwise extension of the table leg. The table has a catch device adjustable between an open position and a closed position for the swivel joint by means of which the table top is fixable in different swivel positions relative to the pedestal. The table top is connected so that it is rotatable about a rotation axis oriented more or less perpendicular to its horizontal plane and is drive connected to the catch device so that said catch device is adjustable between the open position and the closed position by turning the table top about the rotation axis.
