A method for manufacturing an enamel-coated bullet is described. The method starts with casting a bullet from a metal material and quenching the cast bullet. After the bullet cools, applying a lubricant to the bullet and sizing the bullet to the appropriate caliber and rinsing the bullets in a solvent. Thereafter, applying an enamel coating to the bullets. The coating uses about 1 part by volume lacquer thinner, about 1.5 parts by volume hardener, and about 2.5 parts by volume epoxy paint. The process continues by contacting the bullets with a moving fluid for a sufficient time that they become dry and heating the bullets in an oven at a temperature of between 150 and 250° F. for a time between 20 and 45 minutes. Finally, the process involves applying a lubricant to the coated bullet and resizing the bullet to the appropriate caliber.

An electrochromic element comprises an ion conduction layer between two conducting substrates, at least one of which is transparent. The ion conduction layer contains an organic compound, which has both a structure exhibiting a cathodic electorchromic characteristic and a structure exhibiting an anodic electrochromic characteristic.

The disclosed laryngeal mask airway device includes a rigid airway tube, a mask portion, and one or more optical fibers. The airway tube extends from a proximal end to a distal end. The airway tube defines an internal passage and a first notch. The first notch extends along a length of the tube from a location on the tube towards the distal end of the tube. The mask portion is coupled to the distal end of the airway tube. The mask portion includes an inflatable cuff. The cuff defines a central opening at least when inflated. The mask portion is insertable through a mouth of a patient to an inserted location within the patient. The cuff surrounds a glottic opening of the patient when inflated and when the mask portion is at the inserted location. A sealed airway passage extends from the proximal end of the tube through the internal passage to the glottic opening when the cuff is inflated and when the mask portion is at the inserted location. The mask portion includes an epiglottis elevator bar that extends from a proximal end to a distal end. The distal end of the bar defines an aperture. The bar is positionable in a resting position and an open position. The optical fibers extend from a proximal end to a distal end. A lens is connected to the distal end of the fibers. The fibers extend through the first notch. The lens is disposed near the aperture defined by the bar when the bar is in the resting position. The fibers and lens provide a view of a region that extends from the lens through the aperture defined by the bar.

A preformed wound shield includes a frame formed of one or more layers of suitable material and any suitable covering. Exudate absorbing or transporting material may also be one of two or more layers of material forming the frame.

An activated carbon material derived, for example, by carbonizing and activating a non-lignocellulosic carbon precursor has a structural order ratio less than or equal to 0.08, and a nitrogen content greater than 0.2 wt. %. The activated carbon material can also have a volumetric capacitance greater than or equal to 70 F / cm3, an area-specific resistance less than or equal to 0.1 ohm-cm2 and / or a specific surface area greater than 300 m2 / g, and is suitable to form improved carbon-based electrodes for use in high energy density devices.
