A magnetized pipe stand assembly includes a tripod that has a central stanchion which has a telescopically adjustable height. An adjusting screw is adjustably positioned in the second portion of the central stanchion. The adjusting screw is movable either upwardly or downwardly in the second portion of the stanchion. A pipe holder is coupled to the adjusting screw and the pipe holder has a pair of plates being perpendicularly oriented with each other to support a pipe. A pair of electromagnets is each integrated into a respective one of the plates of the pipe holder. Each of the electromagnets produces a magnetic field when the electromagnets are turned on to magnetically to restrain the pipe on the pipe holder thereby facilitating the pipe to be precisely welded.

Magnetic coupling devices are disclosed having magnetic field sensors. The magnetic coupling device may include degaussing coils wrapped about pole extension shoes of the magnetic coupling device.

A magnetic clamping device is provided with a magnetic force generating mechanism at which a housing cover body comprising soft magnetic material is arranged centrally at a hollow housing portion, a nonmagnetic metal frame body comprising a nonmagnetic body is made to engage with the outside circumference thereof, a plurality of arcuate nonreversible permanent magnets are arranged in annular fashion within an annular magnet housing space at the back of this nonmagnetic metal frame body, a reversible permanent magnet and a magnetic polarity switching coil disposed peripherally with respect thereto are provided at the back of the housing cover body, and a base cover body that blocks a back opening of the hollow housing portion is provided, the magnetic clamping device being characterized in that the metal frame body is joined in integral fashion to the housing cover body and the baseplate.

Support blocks for printed circuit boards (PCB's) and printed circuit board assemblies (PCBA's), wherein the support blocks are produced from a 3D printing process. The support block including a bottom surface having a vacuum connection; a top surface having at least one vacuum hole; at least one recessed surface that is offset from the top surface; and at least one vacuum channel extending from the vacuum connection to the at least one vacuum hole.
