Most often, the type of material being molded, and its attendant viscosity in its liquid form, is the primary factor that leads to the creation of the unwanted mold flash. [3] The process of removing flash, known as deflashing, is commonly performed via cutting, breaking, grinding, or tumbling. Some foundries use robot autogrinders to remove ...
The White Lightning WLAC-1 is an American four-seat single-engined monoplane designed for amateur construction by Nick Jones and sold as kits by the White Lighting Aircraft Corporation of South Carolina. [1] In the 1990s the aircraft design was sold in kit form by Reflex Fiberglass Works of Walterboro, South Carolina. [2]
Material properties (size, color, texture) of fulgurites vary widely, depending on the size of the lightning bolt and the composition and moisture content of the surface struck by lightning. Most natural fulgurites fall on a spectrum from white to black. Iron is a common impurity that can result in a deep brownish-green coloration.
The edges of the hole may be flanged to increase the rigidity and strength of the component. [1] The holes can be circular, triangular, elliptical, or rectangular and should have rounded edges, but they should never have sharp corners, to avoid the risk of stress risers, and they must not be too close to the edge of a structural component.

A flash suppressor, also known as a flash guard, flash eliminator, flash hider, or flash cone, is a device attached to the muzzle of a rifle that reduces its visible signature while firing by cooling or dispersing the burning gases that exit the muzzle, a phenomenon typical of carbine-length weapons. Its primary intent is to reduce the chances ...
Through-hole (leaded) resistors. In electronics, through-hole technology (also spelled "thru-hole") is a manufacturing scheme in which leads on the components are inserted through holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side, either by manual assembly (hand placement) or by the use of automated insertion mount machines.
The flash pan was at first attached to the gun barrel, but was later moved to the lock plate of the gun. A small amount of finely ground gunpowder is placed in the flash pan and ignited. The flash of flame travels through the touch hole igniting the main charge of propellant inside the barrel. Unlike the cannon, it was not necessary (or ...
