Abstract: Tris(2-hydroxyalkyl)isocyanurates are reacted with alkylene oxides to obtain tris( Beta -hydroxyalkyl)isocyanurate-alkylene oxide adducts, which can be polymerized with polycarboxylic acids. The resultant polyesters are useful as electrical insulating material in wire enamels and varnishes, casting resins, and for making ester-imide copolymers. High alkylene oxide-content isocyanurates are good functional fluids and lubricants.

Abstract: The vehicle sensitive retractor has a pendulum assembly which includes a pendulum dome. A support for the pendulum assembly includes a substantially cylindrical support member having a substantially circular line of contact at its upper end upon which the pendulum dome is disposed. Prior to actuation, the pendulum assembly has an infinite variety of operable static positions to which the pendulum assembly is adjustable according to the position in which the retractor is oriented by virtue of installation in the vehicle. As a result, the retractor may be tilted for installation without having to redesign the pendulum assembly and support. An actuating means is disposed above the pendulum dome. The actuating means is disposed in an unlocked position when the pendulum assembly is in any one of its infinite variety of operable static positions. The actuating means is moved to a locked position by the pendulum assembly during emergency situations to lock a reel and prevent further unwinding of a safety belt from the reel.

Abstract: This pyrotechnic composition is adapted, upon combustion, for generating a low-flame temperature, non-toxic gas for inflating a vehicle safety bag or other inflatable device. The composition comprises: a fuel, such as a carbonaceous material, aluminum or magnesium; an inorganic oxidizer, such as a metal chlorate, a metal perchlorate, a metal nitrate, ammonium chlorate, ammonium perchlorate or ammonium nitrate; and a coolant or combined binder and coolant, such as magnesium carbonate, magnesium hydroxide or a mixture of magnesium hydroxide and magnesium carbonate. A typical example of this composition comprises: carbon as the fuel; potassium chlorate as the oxidizer; and magnesium carbonate or a mixture of magnesium hydroxide and magnesium carbonate as the binder-coolant. One may use as much of this later mentioned binder-coolant as is necessary to obtain the desired binding properties in the composition, without raising the flame temperature of the gas to an unacceptable level.

Abstract: A method of producing a concentrated sodium carbonate solution low in calcium from calcined natural trona to minimize the deposition of pirssonite on the surfaces of processing equipment exposed to the solution from which the insoluble impurities, normally present in natural trona, have been separated. The method comprises dissolving the calcined trona in a hot aqueous medium to form a concentrated solution containing insoluble impurities and soluble calcium salts and adding an amount of pirssonite effective to insolubilize the major portion of the soluble calcium in the sodium carbonate solution. The pirssonite may be added to the calcined trona either before, during or after its dissolution. The pirssonite may also be added by recycling excess muds back to the sodium carbonate solution from which the insoluble impurities have not been separated. In addition, the sodium carbonate solution may be aged in the presence of the contained insoluble impurities prior to their separation from the sodium carbonate solution to reduce the amount of soluble calcium salts.
