A magnet release device and of the type having a hinge barrel 11 or hinge post 13 affixed to the periphery of the magnet, using a rotating lever arm A 15, which is cam shaped with a leverage tool port 26.

A jig has a frame, a carrier and a hood latch supporting assembly. The frame has two first shafts and a bracket attachment portion. The carrier has two sliders and a second shaft. The two sliders are fitted to the first shafts for movement in a Z-direction along the first shafts. The second shaft is perpendicular to the first shafts. The two sliders and the second shaft are rigidly fixed to one another. The hood latch supporting assembly has a second slider and a latch support portion. The second slider is fitted to the second shaft for movement in an X-axis direction along the second shaft. The latch support portion is coupled to the second slider for movement therewith. The frame assembly allows movement of a latch mechanism loosely fitted to a bracket during alignment of the latch mechanism to the bracket.

A method of milling a piece of raw steel stock comprising: arranging a minimum of four solid pole extensions on top surface segments of a magnetic chuck such that the solid pole extensions are relatively evenly distributed under a piece of raw steel stock and within 2 inches of a perimeter of the piece of raw steel stock; arranging multiple mobile pole extensions beneath the piece of raw steel stock and on every other top surface segment of the magnetic chuck under the piece of raw steel stock that is not occupied by the solid pole extensions but beneath the piece of raw steel stock, each of the multiple mobile pole extensions having a biased top portion that contacts the piece of raw steel stock; and milling the piece of raw steel stock with a face mill that generates steel chip as swarf.

Holders for nanofiber sheets that can reduce the probability of damage to a nanofiber sheet during transport, handling, or experimental preparation are described. These holders can improve the convenience with which nanofiber sheets can be manipulated. Holders generally include two features: an outer case and a clamp disposed within the outer case. The clamp, which can be embodied in any of a variety of ways, mounts to a peripheral edge at one or more locations on the nanofiber sheet. The nanofiber sheet is held fixed in place within the outer case and is suspended within the chamber defined by the outer case and the client.

Apparatus and methods for aligning heavy metal plates during tank construction using an alignment device, which is temporarily attached to the heavy metal plates with a pair of locking members pivotably coupled to a frame and a pair of adjustable alignment members attached to the frame between the pair of locking members. The alignment device may be attached to the heavy metal plates without the inefficiencies, hazards and other disadvantages associated with welding.

An electric permanent magnet chuck, comprising a casing (1), the casing being provided thereon with at least one open inner cavity; reversible magnetic material (2) is provided at a lower portion of the inner cavity, and a coil (3) is arranged in the inner cavity along an outer wall of the reversible magnetic material; a magnetic pole (4) is superposed and fixed in the inner cavity, an annular groove being provided at a lower surface of the magnetic pole, and permanent magnetic material (5) that matches the annular groove being disposed in the annular groove. The electric permanent magnet chuck has the advantages of a simple structure, low processing difficulty, good sealing performance, small magnetic loss and so on.

An embodiment of the present disclosure provides a welding fixture, including: a base; a supporter; a fixing device arranged to fix a member to be welded on the supporter; and a damping hinge which includes a first hinge plate, a second hinge plate and a pivot, the first hinge plate being fixed to the base, the second hinge plate being fixed to the supporter, wherein each of the first hinge plate and the second hinge plate has a pivot hole and is connected to the pivot via the pivot hole, and wherein the pivot is fitted into the pivot hole of each of the first hinge plate and the second hinge plate by interference. An embodiment of the present disclosure provides a welding method using the welding fixture.

A transfer device includes first and second transfer members which are movable into a first transfer state on opposite sides of a first transfer plane (P1). The first transfer member includes first magnetic field sources that form a first magnetic field array for retaining the tire component with a first magnetic attraction force (F1), while the second transfer member includes second magnetic field sources that form a second magnetic field array for retaining the tire component with a second magnetic attraction force (F2) that is larger than the first magnetic attraction force (F1) at the first transfer plane (P1), wherein in the first transfer state the second magnetic field array is offset with respect to the first magnetic field array.
