An apparatus for manufacturing a bracket-integrated double-layer door impact beam is provided. The apparatus includes a lower mold having a lower cavity formed with a base material molded to have a U-shaped cross section and a predetermined length. The base material is seated on the lower cavity. A lower electrode terminal is disposed in the lower mold to contact the base material. An upper mold has an upper cavity therein and is coupled with the lower mold to pressurize both end portions of the U-shaped cross section of the base material inward to form the base material with an O-shaped cross section. An upper electrode terminal is disposed in the upper mold to contact the base material.

A tool assembly for forming a workpiece with an outer surface into a housing with a non-round design outer profile. The tool assembly includes a number of jaw segments, each jaw segment having an internal surface for engaging the outer surface. The jaw segments are movable between a first condition and a second condition, in which the internal surfaces of the jaw segments substantially define the design outer profile of the housing. Each internal surface has a preselected end point associated therewith defined by a radius centered on the preselected end point that is substantially coincident with the portion of the design outer profile defined by the internal surface. Each jaw segment is movable toward the preselected end point therefor when moved from the first condition to the second condition, and away from the preselected end point therefor when moved from the second condition to the first condition.

The invention relates to a heat transfer tube (9) for falling film evaporation having a heating medium surface (21) to be heated by a heating medium, a falling film surface (20) to have spent liquor passing over it, and being made from an sheet metal material. The falling film surface of the heat transfer tube is equipped with a multitude of wire bumps (WB), each wire bump being spaced apart along the longitudinal axis (CC) of the heat transfer tube from a neighbouring wire bump by 3-300 mm, said wire bumps (WB) having a height (h) in the range 0.3 to 5.0 mm, a width (w) in the range 0.3-5.0 mm, and an inclination angle (a) versus a plane orthogonal to a longitudinal axis (CC) of the heat transfer tube in a range of 0-70 degrees. The invention also relates to a method for manufacturing said heat transfer tube.

This invention relates to a solenoid housing and to a method for providing a solenoid housing having the base, wall, center pole, and flange integrally connected as a single piece. The instant invention provides for mounting protrusions and window for electrical leads as an integral part of the housing and manufacturing process.

The invention relates to a heat transfer tube (9) for falling film evaporation having a heating medium surface (21) to be heated by a heating medium, a falling film surface (20) to have spent liquor passing over it, and being made from an iron based high alloy stainless steel material with an alloy content above 16.00% for Chromium and above 1% for Nickel. The falling film surface of the heat transfer tube is equipped with one or several protrusions/indentations forming a multitude of stamped bumps (SB) on the envelope surface of a heat transfer tube such that the distance between adjacent stamped bumps (SB) along a line on the envelope surface parallel to the longitudinal axis of the heat transfer tube is within the range of 3 to 250 mm, said stamped bumps (SB) having a height (hp) in the range 0.3 to 5.0 mm, a width (wp) in the range 1.0-20 mm, and an inclination angle (a) versus a plane orthogonal to a longitudinal axis (CC) of the heat transfer tube in a range of 0-70 degrees so that each stamped bump (SB) is inclined and extends along at least a portion of the heat transfer tube or extend within a plane orthogonal to the longitudinal axis of the heat transfer tube. The invention also relates to a method for manufacturing said heat transfer tube.
