An amputation system includes a cutting element having a cutting blade traversing a V-shape. The V-shape has a vertex and an angle in a range of 90-120&#xb0;. A rod, rigidly coupled to the cutting element, has its longitudinal axis aligned with the vertex so it bisects the angle of the V-shape. A barrel having a bore receives at least a portion of the rod therein wherein the rod's outboard end resides in the bore. An energetic energy source, positioned in the bore adjacent to the rod's outboard end, generates a pressure force that is incident on the rod's outboard end. The pressure force is one that peaks within 0.5 milliseconds to propel the rod from the bore at a velocity in a range of 300 to 1000 feet per second.

An apparatus for curing cylindrical shaped elements having a liner, especially a liner of a rocket motor sleeve, where the cylindrical shaped elements are cured during rotation in a horizontal orientation. Horizontal rotation produces a liner with a substantially uniform thickness. The apparatus is mobile, compact, and has built-in robust safety mechanisms not compromised by the heat used to effect a cure. The cylindrical rollers are easily cleaned with minimal cross-contamination of one lot to another. Dripping of elastomeric materials from one assembly of rollers onto a stackable assembly of rollers below is eliminated. Each stackable assembly of rollers is independently controlled where each assembly is driven by its own motor, so rotation of one assemble does not affect another assembly of rollers.

An ignition element is provided for integration into a primer assembly. The ignition element includes an electrode housing including at least one cavity and an electrode disposed in the electrode housing. The electrode housing and electrode are electrically isolated from each other using insulators. A bridgewire and a primary ignition charge are located in the cavity such that upon application of current to the electrode the pyrotechnic ignition charge is ignited. A headstock is provided, and the electrode housing is threadably disposed within the headstock. Burst disks cover the cavity and separate the ignition charge from a primer charge containing powder disposed in a single booster holder.

A mechanical coupling arrangement includes first and second pins and a sphere. When coupled, the pins are longitudinally aligned and include partial portions that face one another. The second pin's partial portion includes a recess formed therein that faces the first pin's partial portion. The recess is spherically-shaped to be smaller than a hemisphere. A sphere is ring-staked into the first pin's partial portion and is seated in the recess.
