DEFINITION

Classification: 102/289

Having embedded reinforcing or burning control means:

(under subclass 283) Subject matter including structural means within the form to (a) strengthen the form, (b) change the surface burning area of the form, or (c) change the burning rate of the form.

(1) Note. The form material can be heated to the ignition temperature where it contacts the structural means heated by conduction from the burning propellent or heated by the ignited structural means ignited by the burning form. This heating changes the burning surface area of the form and the burning rate of the form.

(2) Note. The "structural means" excludes flakes, powders, chips, or particles of metal used as a burning rate additive in the propellent composition.

(3) Note. The "structural means" includes metallic wires, fiber glass strands, sheets of corrugated metal, wire screen, hardware cloth, or the like.

(4) Note. The "structural means" includes form supporting means which inherently reinforces the form or it may be a burning front guide means which functions to direct the flame front through a preselected path in the propellent form.
