A joint fastening system employs a lock bolt having a pull stem and locking threads inserted through a bore in a joint having fay sealant between layers. A collar is received over the pull stem to engage the threads, the collar producing tension on the threads to generate clamp force sufficient for fay sealant squeeze out.

System and method for mounting one or more photovoltaic modules includes one or more flexible rods, including a first end and a second end opposite the first end, each of the one or more flexible rods further including an inner core and a first jacket surrounding the inner core between the first end and the second end. The first end is configured to be attached to at least one photovoltaic module using one or more first adhesive materials. The second end is configured to be inserted into at least one hole of a modular rail and attached to at least the modular rail using one or more second adhesive materials. The one or more flexible rods are configured to allow at least a lateral movement in a first direction between the photovoltaic module and the modular rail and support at least the photovoltaic module in a second direction.

A device and corresponding methods for applying a coating material are disclosed. The method may include applying a first coating material on a threaded region of an opening in a multi-piece assembly, and inserting at least one fastener to the threaded region. The fastener may include a mating thread selectively secured to the threaded region of the opening to create a first friction interface between the fastener and the multi-piece assembly. The method may further include tensioning the fastener between a load surface of the multi-piece assembly and the mating thread. In one example, the load surface may define in part a second friction interface between the fastener and the multi-piece assembly that is spaced away from the threaded region such that the first coating material does not influence the second friction interface. In another example, the first coating material may be applied in a substantially uniform thickness.

A cap for use in covering a portion of a fastener protruding from a surface is provided. The portion includes threads. The cap includes an interior, a base that at least partially delimits the interior, a threaded receptacle on the interior configured to threadably engage the portion of the fastener, and a seal coupled to the base to engage the surface.

In an ultrasonic transducer assembly, a conformable ultrasonic transducer has a piezoelectric layer and electrodes able to conform to curved surfaces, and a clamp for pressing the transducer into ultrasonic contact with a curved surface. Conformability is ensured with a thin, porous piezoelectric layer and suitable electrical conductors and insulators. The ultrasonic transducer may operate without further thermal shielding under harsh environments and/or at high temperatures.

An anchor for lightning protection systems include a base and pad that extend over a sufficient area and a sufficient bearing length to hold in shear and in tension against the weight, shear force, and moment of cables, points, and other components of a lightning protection systems. The mounting anchor is non-penetrating, and adheres to a vertical surface almost immediately without requiring damage to structures, long term support over days waiting for cure, and works in overhang situations as well. An integrated clip may be constructed with the base from sheet material. Adhesion of the base to a cover material on a wall or parapet may be promptly followed by snapping cable into clips formed monolithically with the base.

A manufacturing method of a casing is provided. First, a plate, a frame and a main shell are provided, wherein the plate has an adhering region and at least one thermal fusion region, and the frame has a first surface and a second surface opposite to each other. Then, the plate is stacked on the first surface of the frame, wherein the thermal fusion region is overlapped with the frame, and the adhering region is not overlapped with the frame. The main shell is adhered to the adhering region of the plate and the second surface of the frame. The thermal fusion region is fixed to the frame by thermal fusion. In addition, a casing manufactured through the above-mentioned method is also provided.

The present invention discloses a system for securing at least one fastener to an implant. At least one adhesive capsule is inserted in a recess preferably located along a longitudinal axis of the implant. The at least one adhesive capsule may be inserted in the recess and held in place therein by a holder. A plurality of adhesive capsules and holders may be inserted in one or more recesses located substantially along the longitudinal axis of the implant. The at least one adhesive capsule preferably has a casing housing an adhesive material configured to be pierced by the at least one fastener to secure the at least one fastener to an aperture of the implant. The casing of the adhesive capsule may form an annular passageway to receive a guide wire for aiding the insertion of the capsule in an implant having a longitudinal bore along at least a portion thereof.

A method of connecting and using a safety cover for a socket that includes a front plate connected to a rear box using one or more screw-headed bolts includes the steps of loosening, but not removing, the one or more screw-headed bolts connecting the front plate to the rear box, moving the front plate outward away from the rear box so that a frame included with the safety cover can be slid onto the front plate, sliding the frame onto the front plate so that a lip included with the frame is disposed between the front plate and the rear box, and tightening the one or more screw-headed bolts so that the front plate is connected to the rear box with the lip from the frame gripped between the front plate and the rear box.

A system for use in covering a portion of a fastener protruding from a surface is provided. The system includes a cap that includes an interior, a base that at least partially delimits the interior, and pawls on the interior. The system may also include a tooth configured to be associated with the fastener and configured to positively engage the pawls.
