System for Measuring the Concentration

of an Additive in a Mixture

US 2014/9194858

Classification Oil and Testing for Contamination

Abstract: An apparatus and method for determining a concentration of an additive in a mixture is provided. The apparatus for determining the concentration of an additive in a mixture comprises a distillation system, a filtration system, a detection system and a fluid transportation system. An alternative apparatus is a portable apparatus comprising a distillation system, a filtration system, a detection system and a fluid transportation system removably coupled to a portable container. A method for determining the concentration of the additive in the mixture includes concentrating the additive in the mixture, removing the additive from a fraction of the mixture and measuring a spectral signature of both the non-additive fraction of the mixture and the mixture. A spectral signature value of the non-additive fraction of the mixture to the mixture is determined and then compared to spectral signatures of a plurality of reference mixtures containing known concentrations of the additive.

Where are we on this Technology Package?

Fuel Analyzerr: Current methods employed for measuring concentration of corrosion inhibitor/lubricity improver (CILI) in fuel involves several time consuming steps requiring a large consortium of laboratory instruments.  This self-contained portable instrument that measures CILI in less than 5 minutes, with 5ppm accuracy, and requires very little skill to operate. This system utilizes patent pending sample preparation and differential spectral technology, that achieves accuracies previously not possible. The size, portability, ease of use and price point this system will allow fuel suppliers to qualify fuels at the point of use in the U.S. and internationally.  Our technology currently measures corrosion inhibitor and lubricity indicator in fuels. However, with additional short-term development, the same technology can be used to quantify other fuel additive concentration and quality metrics. This is a novel test kit technology. It is a suitcase-sized instrument operable by a technician. Advantages.This kit provides a path for measuring low concentrations of CILI in minutes, whereas available techniques require skilled labor, several steps and laboratory equipment.

Low Temperature Smoke 

US 2017/9617195 

Entertainment, Leak Detection, Marking, Wind Indication, Security, Obscuration

A smoke producing method and device of the present disclosure produces a non-incendiary, organic-polymerization based, smoke-producing reaction. The method of generating smoke comprises initiating a frontal polymerization reaction by heating a composition comprising a monomer compound that exothermically polymerizes upon initiation with an initiator compound and an initiator compound that initiates polymerization of the monomer compound present at a mass concentration that is at least five percent of the mass concentration of the monomer compound. The polymerization of the monomer compound is exothermic, and in one embodiment the concentration of initiator compound is at least five percent of the concentration of monomer compound. The smoke mainly comprises thermal decomposition products of the initiator compound.

This method for opaquing visible and infrared radiance is being explored.

Capsaicinoid Smoke 

US 2017/0267602 

Flameless Obscurant

A smoke producing method and device of the present disclosure produces a non-incendiary, organic-polymerization based, smoke-producing reaction. Some versions of the smoke are effective carriers for capsaicinoid compounds. The method of generating smoke comprises initiating a frontal polymerization reaction by heating a composition comprising a monomer compound that exothermically polymerizes upon initiation with an initiator compound and an initiator compound present at mass concentration that is at least five percent of the mass concentration of the monomer compound.
