The invention is a passive control technique effective in eliminating reverse flow instability. The invention preferably includes two flow stabilizers each preferably having a planar face. The flow stabilizers are disposed at an exit end of an injector so that the planar faces oppose each other and diverge in a direction normal to the flow of the gas passing through the injector.

Stabilizer for submerged gaseous jets in liquids

An electro-optic memory effect providing for storing, erasing and rewriting igital information relies upon a ferroelectric polymer, polyvinylidene fluoride. Recent development of tri-fluoroethylene copolymers of this material with Curie temperatures below the melting point provides a means of selective writing, storage and erasure. The advantage of the polyvinylidene fluoride material for optical recording is its high chemical and physical stability. This material provides a mechanism for bit-by-bit erasure and long time storage of information.
