This mounting plate is sandwiched between the flange and an outer face of the hardened plate and has an outer periphery spaced well outward of the flange. A plurality of nuts bear on an inner face of the hardened plate in line with the flange.

Abstract: A gasket system for sealed interfaces utilizes a carrier ring having inner and outer compression stops to account for and control flange rotation effects in order to achieve a uniform and constant gasket seating stress across the sealing region. The inner compression stop provides a fixed fulcrum for flange rotation. The inner and outer compression stops have different heights, dependent upon the characteristic flange rotation, that allow the orientation of the sealing material to be angularly matched to the flange side profile and that allow the sealing material to be fully captured within the sealing region upon full compression, minimizing creep relaxation. A visual compression indicator on the circumference of the carrier ring permits assembly of the interface without the use of specialized or calibrated tools.

Abstract: A connecting plate for connecting I-beams together. The connecting plate contains at least two plates that each have a series of holes drilled in them. These series of holes are drilled offset from each other in each plate. The connecting plate can be in the form of a flat face, an L-shaped plate or a partially H-shaped plate. The offset holes on these plates allow the plates to be connected to a first I-beam first, and then connected to a second I-beam. This design allows a user to forgo coupling the first I-beam, the coupling plate and the second I-beam together all at the same time which improves the safety and efficiency of coupling I-beams together.

Abstract: Couplers for joining actuators to valves are configured to allow their affixment to different makes and models of actuators and valves, thereby allowing an off-the-shelf S coupling solution and avoiding the need to specially construct a coupler which is only adapted to connect whatever valve and actuator that are desired for coupling.
