An apparatus for fabricating an internally finned pressure vessel includes a plurality of positioning discs, each of the positioning discs defining a plurality of circumferentially spaced slots extending radially into the positioning disc from a perimeter thereof, and one or more rods extending through the plurality of positioning discs, the plurality of positioning discs being held in axial alignment by the one or more rods. A method of fabricating the internally finned pressure vessel includes providing the apparatus, loading a plurality of fins into the slots of the positioning discs, inserting the apparatus containing the plurality of fins into a pressure vessel, attaching the plurality of fins to the pressure vessel by a brazing process, and removing the apparatus from the pressure vessel.

A magnetic hand tool and method of assembly for manipulated conveyance over a surface for magnetic collection of ferrous articles, by which procedure a quick-release cap is used to release any and all collected ferrous material. This tool utilizes an alignment insert in a central opening of the magnet to coaxially align fastener guide holes through polar plates or protective covers on opposing planar sides of the magnet and a fastener guide hole in the insert, whereby insertion of the fastener through the guide holes laterally aligns the components of the assembly. The invention is the release device/cap, that is part of the assembly by means of a self-adhering or hinged cap with a lip, square, circular or other shape, to aid in the separation of ferrous material from the magnetic tool by pushing away the cap from the magnetic hand tool by holding the lip for that purpose. The divots make it that the release lever device/cap is held onto the magnetic hand tool assembly. The separation allows for the ferrous material to fall in the drop collection box by ways of gravitational pull.

The present disclosure relates to a magnetic apparatus for magnetically anchoring ferrous elements (P1), comprising a support structure (11) in which thickness (S) a plurality N of polar units (30A) is housed, said support structure (11) identifies a first and a second side (12, 13) at the opposite surfaces with the greatest extension, each of said plurality N of polar units (30A) comprising a coil (30) having a support (31) of predetermined profile and an electric conductive element (32) wound on said support, a first magnetic core (40) with a first coercive value, generating a first magnetic flow oriented in a first magnetic direction, a plurality of second magnetic cores (90A, 90B) having each its own coercive value, different from said first coercive value. A characteristic of the apparatus is that a first part (90A) of the plurality of second magnetic cores (90A, 90B) generates a second magnetic flow oriented in a second magnetic direction and a second part (90B) of the plurality of second magnetic cores (90A, 90B) generates a third magnetic flow oriented in a third magnetic direction, said third magnetic direction being parallel to said first magnetic direction and of different direction with respect to said second magnetic direction.

A holding device for fastening bar cutters in order for the cutting edges thereof to be coated, wherein the fastening is configured in such a way that a plurality of bar cutters can be arranged in a row such that the cutting faces and tips thereof have the same orientation, and the holding device includes a screen which at least partially protects the cutting faces from the coating, wherein, with bar cutters arranged in a row in the manner described, the top edge of the screen projects beyond the knife tips in such a way that no knife tips protrude.

A magnetic wand is used for adjusting window blinds. The blinds include slats and a slat angle adjustment mechanism. The wand includes an upper housing portion and a handle portion. The upper housing portion has a connecting mechanism disposed on one end and a docking area on a second end. The connecting mechanism is adapted to connect the upper housing portion to the window blinds. A first magnetically attractive element is disposed within the docking area. The handle portion has an end shaped to fit within the docking area. The end includes a second magnetically attractive element. The second magnetically attractive element is adapted to releasably couple with the first magnetically attractive element through magnetic coupling, forming a magnetic joint. That magnetic joint is configured to prevent the handle portion from longitudinally rotating independently relative to the upper housing portion.

A magnetic vise base apparatus for quickly installing a vise on any ferrous surface includes a base having a top platform and a pair of side walls perpendicularly coupled to the top platform. The top platform is configured to receive a vise. A magnet housing is coupled to the base between the pair of side walls. A magnet is coupled to the magnet housing and comprises a pair of ferrous blocks, a non-ferrous median, and a magnetic core. The magnet has a core aperture extending from a front side to a rear side of the magnet housing, fully through the non-ferrous median and partially into each of the pair of ferrous blocks to receive the magnetic core. The magnetic core is rotatable to magnetize and demagnetize the pair of ferrous blocks. A handle is coupled to a magnet rod coupled to rotate the magnetic core.

A jig for clamping that includes two or more clamping aid tools for use and mounting with various common tools, including a carpenter, framing and speed square, and various straight edges for easily and accurately positioning various objects, either flat and/or round, magnetic or not. The clamping aids can clamp to round pipes at correct angles while being fitted, secured and/or welded together.

Present invention disclosed and claimed a magnetic clamping tool where a clamping arm with a clamping finger serves to clamp on a working object in normal, sideways, or even up-side-down orientations, where the movements of the clamping finger is controlled by a first wing screw and the movement of the clamping arm is controlled by a third wing screw. The clamping arm is releasably attached to a bracket which is further releasably attached to a V-pad by a locking nut. An anti-tipping screw provides a counter-balancing force to the biasing force of a helical spring on the bracket, and is most useful when the longitudinal direction of the bracket is at a 90-degree angle with the longitudinal direction of the clamping arm.

The disclosure herein include a magnetic tool for attaching to and moving a ferromagnetic workpiece that may include: a chassis having a magnetic face; a base rotatably coupled to the chassis; and a handle rotatably coupled to the base.
