Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: An electrical connector system for use with independently heated hoses includes a first electrical connector, a second electrical connector, a third electrical connector, and a fourth electrical connector. The first electrical connector includes a first key that mates with a second key of the second electrical connector. The third electrical connector includes a third key that mates with a fourth key of the fourth electrical connector. The first and second keys differ from the third and fourth keys, ensuring the electrical connectors are correctly connected.

Abstract: An apparatus for permitting both base and flush mounting a device to a surface is disclosed. The apparatus comprises a case housing a device and a frame. The frame is configured to attach to the case in both a base mounting and flush mounting configuration.

Abstract: A trailer door fastener includes a T-nut and a bolt. The T-nut includes a large washer face with a hollow cylinder extending coaxially from and perpendicular to the washer face. The hollow cylinder contains internal threads running the entire length of the hollow cylinder. The bolt includes a large head with a shank extending coaxially from and perpendicular to the head. On the shank adjacent the head is a knurled portion with grooves running parallel to the axis of the shank. The remainder of the shank has external threads running from the end of the knurled portion opposite the head to the end of the shank opposite the head. The bolt is inserted through aligned holes in the hinge plate and the door panel from the outside of the trailer such that the knurled portion traverses the interface between the hinge plate and door panel. This provides a greater surface area on the bolt to withstand shear forces at the interface.

Abstract: This invention relates to improved apparatus and process for manufacture of tunnel modules and tunnel sections used to build underwater tunnel tubes. A collapsible fixture is situated to roll up flat steel plate into a circular shell for the tunnel modules. A hydraulic cylinder is utilized to adjust the diameter of the fixture without collapsing it, in order to close any gaps between the ends of the plate when it is rolled into a shell.
