Abstract: Fastening art with double nuts for a dual-threaded screw structure is provided, in which loosening is not created even if the structure is subjected to vibration. A spring washer is caused to intervene between the nuts, when double nuts of an inner nut and an outer nut are screwed onto a thread portion on which dual-threaded screw is formed. Only by tightening the outer nut, also the inner nut is tightened and the spring washer is compressed. Both axial force for clamping the fastened member and axial force between the nuts can be secured with the spring washer, so that loosening does not occur easily.

Abstract: An adjustable flow restrictor includes a nut, an adjustment screw, and a sleeve. The adjustment screw installs into the nut whereby the adjustment screw and the nut define a pathway therebetween. Adjustment of the adjustment screw relative to the nut varies the pathway with respect to a length thereof. The sleeve fits over the adjustment screw and mates with the nut in order to define a chamber with an outlet. The pathway receives therein a liquid conveyed to the nut and communicates the liquid to the chamber for exit therefrom via the outlet. Adjusting the length of the pathway sets the volumetric flow rate of the liquid traversing the pathway such that the liquid exiting the outlet flows therefrom at a desired volumetric flow rate.

Abstract: This invention builds up on technical features and on the industry experience with the use of Merlin™ family connectors. In addition to friction, structural means utilized to transfer high torsional loads include interlocked thread systems and may also include: dog-clutch teeth, shear pins, keys and splines, all used in isolation or in arbitrary combinations. Static and fatigue bending load capacities of the connectors remain high, while the axial load capacities may or may not be high, depending on the design requirements. Connectors according to this invention can be built as new, carefully optimized designs. In some cases upgrading existing Merlin™ family connector designs to increase they torque transfer capacities may be also feasible.

Abstract: A fastening system has a conditioner clamp and a penetrating fastener. The conditioner clamp has an upper assembly and a lower assembly attachable together to define a conductor cavity therebetween. At least one threaded opening provides ingress into the conductor cavity. The penetrating fastener is extendable through the at least one threaded opening. The penetrating fastener has a threaded bolt and a penetrating portion with a proximal end at a second end region of the threaded bolt and a distal end spaced therefrom. The penetrating portion has a frustoconical configuration terminating at a tip portion. The tip portion is configured to penetrate into a conductor positioned within the conductor cavity.
