A spring tool for actuating explosive fasteners for driving nails into a substrate is disclosed. For the tool to operate at its maximum potential the firing pin guide should be pushed securely against the rear of the fastener and the tip of the fastener should be pushed securely against the substrate. The action of the operator pushing the tool forward to actuate the tool moves the trigger body forward while compressing the firing spring until the trigger body travels the exact distance needed to release the trigger ball. The trigger body must also be in optimal rotational orientation with the tool and means for accomplishing the alignment is disclosed.

For a spring tool for actuating explosive fasteners to operate at its maximum potential the firing pin guide should be pushed securely against the rear of the fastener and the tip of the fastener should be pushed securely against the substrate. To achieve this, the action of the operator pushing the tool forward to actuate the tool moves the trigger body forward while compressing the firing spring until the trigger body travels the exact distance needed to release the trigger ball. A step or backstop insert is added to the inside of the trigger body such that at the exact distance where the trigger ball is released, the step contacts the rear of the firing pin guide so that all internal components of the tool to form a solid (contacting) stack, from the tip of the fastener to the end cap of the tool.

An improved tool for installing an explosively driven fastener as well as an improved explosively driven fastener for use therewith are disclosed. The fastener includes a nail having a head with an explosive load attached thereto in a plastic cap that includes a buffer. The tool has a plurality of concentric cylinders and springs including a muzzle for receiving the fastener head and explosive load. A spring actuated firing pin ignites the load causing it to explode and drive the nail out of the tool. The explosion also automatically resets the tool. The tool and the fastener provide many advantages over existing explosively driven fasteners and the tools used to install them.

A stilt comprises a floor platform, a shoe platform, parallel supports extending between the platforms, a leg support extending above the shoe platform, and a yoke connecting the leg support to the shoe platform. The pair of parallel supports is substantially vertically mounted supports pivotally connecting the floor platform and the shoe platform. The vertical supports are spring-biased so as to maintain the vertical supports and the platforms in a parallelogram configuration. The leg support is mounted to one of the vertically mounted supports and to the shoe platform. The mounting includes a capturing bracket for engaging the lower end of the leg support. The yoke engages the leg support at the attachment to the shoe platform. A key closely engages depressions in the yoke and the leg support to resist twisting of the leg support.

The present invention advantageously provides several systems and methods for solving the trombone routing issues within an IMS/MMD network. These approaches avoid trombone routing, speed up handoff, and increase the efficiency of signaling and overall performance of an IMS/MMD network. These solutions can broadly be divided into the following categories. Piggy-backing SIP registration over MIP (Split at FA); Selective Reverse Tunneling and Tunneling between FA and P-CSCF; the SIP-based mobility protocol; use of CoA during SIP registration and call up in MIPv6; Piggy-backing SIP registration when HA and S-CSCF Co-exist; Using Dynamic Home Agents in MIPv4 FA-CoA; and the Interceptor-Caching Approach.

A punch for making holes in sheet stock is disclosed having three main components, a frame, a lever arm, and a plunger. The frame defines a tool head with a handle extending therefrom. The tool head defines a lower jaw and an upper jaw. The upper jaw is spaced apart from the lower jaw to define a first slot opening into the tool head from the first lateral side between the upper jaw and the lower jaw. The stock to be punched can be received and positioned by the slot. A plunger is mounted in the lower jaw for sliding movement toward the upper jaw. A lever arm extends into the tool head and actuates the plunger around a pivot point in the tool head upon being urged toward the handle.

Punch

A lock assembly comprising a housing, a control mechanism, one pin or two pins supported by the housing for shifting movement of the pin or of the two pins in a direction transverse to direction of movement of the control mechanism between a locked position and an unlocked position and a spring for each pin for enhancing the shifting movement of the corresponding pin toward the unlocked position and for automatically returning the corresponding pin toward the locked position upon release of the control mechanism. When the control mechanism is pushed manually, the pressure which is exerted upon pushing the control means compresses the spring around the pin or two pins which each shifts in a direction transverse to direction of movement of the control mechanism between the locked position and the unlocked position. Meanwhile, shifting of the pin or of the two pins permits the sliding of a cut-out section of the control mechanism until the pin or pins strike against the cut-out sections of the control mechanism. As soon as the movement is stopped, the pin or two pins which are acted on by the spring assume a position which assures locking. As soon as the control mechanism is released, the pin or two pins immediately and automatically return to the locked position again.
