Abstract: A strain measurement device includes a reference material, and a displacement sensor configured to detect relative changes in distance between the sensor and the reference material. At least one of the displacement sensor and the reference material is coupled with a pre-cured elastomeric material. The displacement sensor generates a data signal to a processor that is configured to determine a strain of another elastomeric material based at least in part on the data signal received from the sensor. A displacement sensor and a reference material may be positioned within an elastomeric material within a casing of a solid rocket motor for determining strain experienced by the elastomeric material, such as the propellant of the solid rocket motor. A method includes installing a sensor of an elastomeric material. Another method includes determining strain of an elastomeric material of a solid rocket motor.

Abstract: Novel process for peeling fruits and vegetables which yields maximum skin removal coupled with minimum weight loss. The primary feature of the invention is loosening the skin by applying multiple heat treatments, each followed by a cooling step. Each of the heatings is ineffective by itself to attain loosening of the skin, but the multiple heatings in aggregate and in conjunction with the coolings yield effective loosening of the skin without cooking the flesh of the fruit or vegetable being peeled.

Abstract: System for peeling fruits or vegetables wherein the peel is loosened by a double treatment with lye, each treatment being followed by a holding period. After the second holding period, the peel is removed directly, that is, without any application of radiant or other heat.
