Abstract: A method of producing a measuring tape may include providing a cupped blade with substantially uniform cupping over a longitudinal length of the cupped blade, applying a stress relief operation to a selected portion of only a convex side of the cupped blade to increase curvature of the cupped blade in the selected portion of the cupped blade where the stress relief operation includes bead blasting the selected portion via a dual nozzle shot peening assembly to define a combined bead blast area that is substantially centered with respect to a longitudinal centerline of the blade, and operably coupling the cupped blade to a reel assembly and providing the cupped blade and reel assembly within a housing to define the measuring tape device.

Abstract: A front wheel double suspension triangle frame for four-wheel drive automobile having a z shaped double layered triangle frame, a lower platform of which is connected with a shock absorber and the outer end thereof is secured onto a joint of a lower seat on a spindle knuckle of a hub, a short ratchet arm and a long ratchet arm are formed on the inner end of the above end face to extend upward obliquely at the same angle of elevation and pivotally connected with a beam so as to raise the chassis; an upper triangle frame pivoted on the seat of the automobile body; and a steering joint equal to the height between the upper and lower end of the lower triangle frame and pivoted between the steering joint of the upper triangle frame and an upper seat of the spindle knuckle of the hub for the upper and lower triangle frame to keep them horizontal.
