Abstract: A fastener-installation system is described that includes a driver to drive a fastener into a structure and a fastener feeder to load the fastener into a loaded position of the driver. The fastener feeder includes a fastener magazine to hold a plurality of fasteners. The fastener-installation system further includes a driver head having a plurality of jaws moveable between a closed position and an expanded position. In the closed position, the plurality of jaws form a piercing tip to pierce material of the structure. Further, the jaws spread apart the material of the structure when the jaws move from the closed position to the expanded position to create a path through the material through which the fastener is driven.

Abstract: A method of using a retention clip to secure hardware is provided. The retention clip may include a support surface having an aperture extending through the support surface. The retention clip may further include two anti-rotation surfaces extending from the support surface in a non-parallel direction, and at least one angled tab extending from the support surface in a non-parallel direction towards the aperture of the retention clip. The at least one angled tab may be elastic below a preset load placed on the at least one angled tab, and the at least one angled tab may deform and lose its elasticity above the preset load.

Abstract: A retention clip for hardware may include a support surface having an aperture extending through the support surface. The support surface may surround an entire perimeter of the aperture. The clip may further include at least one anti-rotation surface extending from the support surface in a non-parallel direction, and a plurality of angled tabs extending from the support surface in non-parallel directions towards the aperture. At least a portion of each angled tab may be disposed directly below the aperture. The tabs may be elastic below a preset load placed on the tabs, and the tabs may deform and lose their elasticity above the preset load.

Abstract: Low density alkaline earth metal sulfate fillers are used at levels below 40 phr in polyvinyl chloride thermoplastic resin formulations to improve processibility of the resin formulation and produce a thermoplastic material having retention of elongation and penetration resistance superior to known high temperature PVC thermoplastic materials.

Abstract: Magnesium oxide and a zinc salt are reacted with one another to form a magnesium zinc complex salt which is added to a halogen-containing plastic composition to serve as a smoke and/or fire retardant during combustion of the plastic. This magnesium-zinc complex salt is normally added along with an antimony compound but may be used alone if desired.

Abstract: Zinc is added to a halogen-containing plastic composition with or without a flame retardant additive to serve as a smoke suppressant during combustion of the plastic.
