Abstract: A hardhat shell has a suspension that is secured to the shell by a hanger. The suspension has a horizontal band portion for extending around a user's head, and the suspension is positioned within a hardhat shell. At least one hanger is connected to the suspension for securing the suspension to the shell. Each hanger has a hook at a first end of the hanger, a latching surface located towards the middle of the hanger, and a lever arm at a second end of the hanger. At least one mount is formed on the inner surface of the shell. Each hanger is configured to securely engage a respective one of the mounts, with the latching surface of the respective hanger being in frictional engagement with the respective ledge surface of the mount. By manually pivoting the hanger, a user can cause the latching surface to disengage from the ledge surface.

Abstract: A method and apparatus for soldering wires of components on PC boards to a lead frame. Wires from the electronic components on a PC board supported by a fixture are led through respective pathways and particularly plated grooves on each side of the PC board. The wires within the pathways are held there by being adhered to a temporary fixture beneath the board until the wires are later affixed in their grooves by dipping the sides of the PC board in a solder pool. The excess wire tails are cut away. The PC board is then mounted on a lead frame, and the leads of the lead frame are aligned with respective pathways of the PC board. The PC board and lead frame are then dipped in solder which electrically connects the wires in their respective pathways to the leads of the lead frame.
