Methods, systems, and apparatus described herein relate to a conformable cold plate for fluid cooling applications. An example method includes re-shaping a tube to contour non-uniform surfaces; and assembling a fluid cooling assembly using the re-shaped tube, the re-shaped tube capable to transfer fluid for cooling of one or more devices.

A solid actuator has an actuator structural unit, a top plate and a base plate. A hollow cylinder part made of maraging steel is heated to a predetermined first temperature at which the maraging steel is in an austenitic state. A corrugated tube is shaped from the hollow cylinder part by a shaping process, while the maraging steel is still in an austenitic state. The corrugated tube is cooled such that the maraging steel is in a martensitic state. The actuator structural unit is inserted into the corrugated tube. The top plate and the base plate are fixed to the corrugated tube such that the actuator structural unit is clamped between the top plate and the base plate at a predetermined pre-tension.

The invention concerns a process for roll straightening crankshafts (8, 8) using crankshaft deep rolling tools (1 to 7), in particular work rollers (18,19) which, while the crankshaft (8, 8) is rotated about its axis of rotation (21), are pressed into the recesses (14 to 17) or radii that delimit the bearing pins (Hi, Pi) on either side with a roll straightening force (27, 30) that constantly fluctuates around the circumference of a bearing pin (H.sub.1 to H.sub.5, P.sub.1 to P.sub.4). Roll straightening is carried out by determining the individual vector (34) of the runout by size and direction (35) at each main bearing (Hi) of the crankshaft (8, 8). The largest (45) or resulting vector (25) is determined from the individual vectors (34), then the main bearing pins (Hi) and crankpins (Pi) of the crankshaft (8, 8) are roll straightened with a roll straightening force (27, 30, 49, 50) the size (25) and direction (26) of the largest (45) or resulting vector (25) of which is between 0 and a multiple of the largest (45) or resulting vector (25).

A device for cold working pipe elements has two or more cams, each having a gear which meshes with a pinion to turn all of the cams. Each cam has a cam surface with a region of increasing radius and may have a region of constant radius extending around a cam body. Each cam also has a traction surface extending around a cam body. A discontinuity in each cam surface is aligned with a gap in the traction surface of each cam. The discontinuities and gaps provide clearance for insertion and removal of the pipe element between the cams to form a circumferential groove when the cams are rotated.
