An apparatus and method for a switch that is activated by a predetermined mechanical load includes a first layer of plastic material, a second layer of plastic material, a layer of elastomeric material having first and second surfaces, the first surface bonded to the first layer of plastic material by a layer of adhesive material and the second surface of the elastomeric material bonded to the second layer of plastic material by a layer of adhesive; and a conductor disposed in contact with one or more of the layers of material wherein a conductive path of the conductor is broken when at least one of the adhesive bonds is displaced by the predetermined mechanical load.

Force activated switch

A baffle system is provided for insertion into a stirred vessel. In order to be able to be inserted through the relatively narrow orifice at the opening of the vessel, the baffle system is collapsible. Due to the structure of the baffle system, it may be inserted through the narrow orifice and then be manipulated, via articulated joints, such that it rests adjacent to the wider walls of the vessel.

Collapsing and telescoping baffles for stirred vessels

This invention relates to a smoke-producing composition containing a dye 1,4,- benzenedicarboxylic acid. The acid is useful for purging slag and solid clinker while lowering the steady state burning temperature of the composition. The coloring agent used by the composition does not degrade. The acid is an efficient coolant for the composition and takes advantage of sublimation reactions to produce the properties enumerated here.

Colored smoke-producing composition

The composition of this invention is a colored-smoke pyrotechnic for use as rocket fuel which can propel a 500 gram grenade assembly along a trajectory of about 100 meters while producing a trail of intensely colored, highly visible smoke. The composition contains ammonium sulfamate, potassium chlorate, sucrose, and an organic dye. The sulfamate ingredient functions as a primary reactant, and forms a large quantity of smoke and other gaseous by-products. The potassium chlorate and sucrose exists as a mixture, and when burning produces a large amount of energy which initiates the reaction sequence. The organic dye in the composition is volatilized by the heat, and subsequently condenses in the exhaust plume to color the smoke trail.
