Abstract: The bond strength between an elastomeric material and a secondary material is improved by applying a coating of isocyanate onto the surface of the elastomeric material prior to bonding the secondary material to the surface of the elastomeric material. The isocyanate is applied to the surface of the elastomeric material by exposing the elastomeric material to an atmosphere containing isocyanate vapor which is substantially uniformly distributed throughout the atmosphere and causing the isocyanate to deposit onto the surface of the elastomeric material. Then casting a second material onto the isocyanate coated surface.

Abstract: Disclosed is a novel method for cleaning an electrostatic precipitator by directing a stream of cleaning gas through a flexible tube positioned inside the electrostatic precipitator. The stream of gas causing the flexible tube to move randomly directing the stream of gas at the precipitator plates with sufficient force to dislodge particles adhered to such plates.

Abstract: The present invention discloses a novel injector for the introduction of iron-containing vapor into a stream of heated oxidized gas wherein the injector has a least two passageways, one for the passage of the iron compound containing vapor and the other for the passage of an insulating gas.

Abstract: An improved method of manufacturing superfine iron oxide particles by introducing a gas mixture of a non-oxidizing gas and an iron-containing compound into a stream of heated oxidizing gas, wherein the improvement resides in the use of an insulated injector to introduce the gas mixtures into the heated oxidizing gas stream.

Abstract: The present invention discloses a method and apparatus for the production of vapors of a liquid iron compound. The apparatus contains a vertical evaporator element which has an internal heating unit and an apparatus for introducing a regulated amount of the liquid iron compound onto the surface of the evaporator element. The evaporator element being enclosed in a gas tight housing into which a purge gas may be introduced to carry the resultant vapors out of the housing to a reactor chamber.Also disclosed is a method for evaporating a liquid iron compound comprising placing the liquid iron compound onto the surface of the heated evaporator element, thereby causing the iron compound to vaporize and then carrying the vaporized iron compound out of the evaporator with a purge gas.Further disclosed is a method for forming iron oxide using the evaporator.

Abstract: An improved hull is disclosed for use on an inboard boat of a relatively increased length, the hull having a generally deep V-shaped bottom surface at the bow slowly transitioning to a relatively flat stern to provide increased lift as compared to conventional inboard boats, to provide a smooth ride yet permit maximized speed and stability for water skiing use, to provide the desirable handling characteristics (such as for turning and maneuverability) found in an inboard boat of relatively shorter length, and to produce a minimal wake for water skiing purposes. The hull is formed with a series of longitudinally-aligned pairs of strakes which, over the majority of their respective lengths, have a negative strake angle. Through the specific placement, the longitudinal commencement and termination, of the respective pairs of strakes, they provide increased lift, improved turning ability, and reduced wake side spray.

Abstract: A method for making a ferric oxide burning rate enhancing catalyst that results in a smaller particle size high surface area catalyst. The method comprises diluting a gaseous iron-containing compound with an oxygen-containing gas at a temperature such that the rate of oxidation is negligible and oxidizing the diluted gaseous iron-containing compound in an oxygen-containing environment. Ferric oxide particles are formed, suspended in the oxygen-containing environment.

Abstract: A method of making a ferric oxide burning rate catalyst that results in a highly active, finely divided burning rate enhancing catalyst. An iron-containing compound that is capable of vaporization at a temperature below about 500.degree. C. is vaporized. A mixture comprising the vaporized iron-containing compound is combusted with a gas that is capable of supporting combustion in an oxygen environment and does not condense below about 100.degree. C. The ferric oxide burning rate catalyst made by this process is particulary adapted for use in a composite solid rocket propellant. This process provides an ultra pure, highly active, finely divided burning rate catalyst.

Abstract: A highly active, finely divided ferric oxide burning rate catalyst and method for making the same. The catalyst is made by vaporizing an iron-containing compound that is capable of vaporization at a temperature below about 500.degree. C., and is capable of forming ferric oxide when reacted with an oxygen-containing atmosphere at temperatures below about 500.degree. C. The iron-containing compound is then oxidized in an oxygen-containing atmosphere. The ferric oxide burning rate catalyst made by this process is particularly adapted for use in a composite solid rocket propellant. This process provides an ultra pure, highly active, finely divided burning rate catalyst.

Abstract: A plastic composite sabot (1) includes an integrally molded rearwardly located deformable shoulder (6) which engages the grooves (10) in a rifled barrel (7). The sabot also includes mid and forward sections (4) and (5) which engage the lands (11) in the rifled barrel, and, an axially disposed projectile retaining chamber (13). An obturator (17), attached by pins to the sabot, drives the sabot and projectile through the barrel on firing. Utilizing a unitary plastic composite sabot substantially lessens manufacturing costs and increases projectile stability while reducing overall weight, thereby optimizing projectile velocity and accuracy while minimizing costs.

Abstract: A continuity tester specifically for tracing wiring and circuit paths on electronic printed circuit board assemblies that will not harm semiconductors or respond to resistances of more than a few ohms. The invention electronically divides the probe voltage down to less than 0.25 volts so that semiconductors cannot be biased into conduction when probed resulting in zero induced test current through them. A low impedance input responses to low resistance wiring continuity only, eliminating false responses that can be caused by measuring through a component. A grounding means is provided to prevent damage from static electric discharges by connecting the probes through a high value resistor to workstation ground.
