    摘要: Spherically polymerized polyolefins can be advantageously stabilized by being treated with at least one emulsion or dispersion containing a stabilizer or a mixture of stabilizers and an amine of formula I ##STR1## wherein R.sub.1 is C.sub.1 -C.sub.20 alkyl which may be substituted by --OH, or is C.sub.3 -C.sub.50 alkyl which is interrupted by one or more oxygen atoms, or is C.sub.1 -C.sub.8 alkoxy, and each of R.sub.2 and R.sub.3 independently of the other is hydrogen or has one of the meanings indicated for R.sub.1, or R.sub.2 and Rphd 3, together with the nitrogen atom to which they are attached, form a 5- to 7-membered heterocyclic ring.

    摘要: A fireplace cooking range and room air heater, in one embodiment installed in a conventional fireplace and in another embodiment freely standing, has: a bottom fire chamber; a cooking range-air heater having a spaced porous grill and spaced above the bottom fire chamber, surrounding walls extending up from the fire chamber and spaced about surface structures of the cooking range-air heater and then converging for exiting the combustion gases into a flue; a flue for carrying the combustion gases out of a dwelling; non-combustible sealing material, as necessary, positioned about the flue to prevent room air from escaping up and around the exterior of the flue; entry doors to close the cooking range-air heater at its room side; entry doors to close the fire chamber at its room side; a room air intake located below the entry doors of the cooking range-air heater and at the top of the fire chamber; and a draft regulator to control the quantity of room air flowing through the room air intake, then flowing down inside of the closed entry doors to the fire chamber, thereby keeping soot and other particles from collecting on the inside surfaces of the closed entry doors, which are often made of tempered glass so the fire may be observed and enjoyed.
