The method and apparatus disclosed herein relates to a precision generator and distributor device for plasma and plasma discharge arc as it particularly applies to electro-thermal chemical gun system operations. A self-adjusting filament erodably controls the formation, energy content, consistency and dimension of a plasma arc in a capillary. Specifically, in cooperation with radially and longitudinally formed perforations in the capillary wall, the filament enables the distribution of a predetermined amount of plasma and plasma-ignited chemical fluid into segments and regions of a combustible chemical in a contiguous chamber to thereby control combustion and increase piezometric and ballistic efficiency of the gun system. More specifically, the filament enables the creation of a plasma arc that is sustainable, definite and consistent and one which yields high pressure and temperature at a reduced ohmic resistance for a given power supply.

A burner system has a control system which operates to prevent startup of the burner if an airflow switch indicates presence of combustion air flow before startup of a blower which provides the air flow. If the airflow switch later indicates absence of air flow before startup, then startup can proceed normally without operator intervention. Power for startup is supplied through the normally closed contacts of a safety relay. The winding of the safety relay receives power through the airflow switch. When the airflow switch is closed the safety relay winding is energized, opening the normally closed safety relay contacts and thereby blocking burner system startup, but only unit the airflow switch opens.

A device which can be held in the fingers of one hand has a thin front edge and an underside curved surface which conforms generally to the contour of a wrapped roll of coins and when the roll is held by one hand, the device is held in the other hand and the front edge slipped under an exposed edge of the roll wrapping and then advanced or moved by either rotating the roll of coins or moving the device under the wrapping to separate the wrapping from the roll of coins to expose the coins.

A resilient wire clip goes around the mouth of a gas latern mantle to hold the mantle securely in place around the opening of the tube and can be manually expanded to release the mantle when it has to be replaced.
