Allosteric Control through Mechanical Tension
Physical Review Letters, 2005Conformational changes of proteins modulate their function. In allosteric control, the conformational change is induced by the binding of a signaling molecule. Here we insert a "molecular spring" on the enzyme guanylate kinase, to control the conformation of this protein. The stiffness of the spring can be varied externally, which allows one to exert a

Bolt Tension Control with a Direct Tension Indicator
Engineering Journal, 1973Achieving the minimum required bolt tension in a high strength bolted friction-type joint is a primary factor, since the slip resistance of the joint is dependent on the bolt tension. Current specifications require that high strength structural bolts be tightened to at least 70 percent of the minimum required tensile strength.

Manufacturing Science and Engineering, 1999
Abstract This paper analyzes the current coil-winding machine to determine the wire tension occurring at various locations along the winding apparatus. The goal is to make possible design improvements for better wire tension control at the armature to prevent wire breakage and to enable high-speed winding.
