    摘要： A polar mount for a satellite dish antenna has the flattened ends of three metal tubes bolted together to form a triangular base having three corners. Three tubular leg members have their corresponding lower flattened ends joined to the respective corners of the base. One leg member constitutes the polar axis shaft. The other two leg members are telescopic and adjustable in length. The upper ends of the two telescopic leg members and the upper end of the polar axis shaft are connected at a common point to create a pyramid-shaped structure. Brackets having bearings mounted to the outside back of the dish and the polar axis shaft extends through these bearings along an axis aligned with a diameter of the dish. The polar axis shaft is at an angle with respect to horizontal corresponding to the degrees of latitude at the antenna location. A tangent to the dish axis is at a declination offset angle relative to the polar axis shaft. The dish rotates on the polar axis shaft through a look angle. The latitude angle is obtainable by bending the polar axis tubular shaft at its flattened end while the other two legs extend or contract. The shaft is directable exactly to true north by shifting said common connection laterally which is accommodated by one of said leg members extending and the other contracting.

    摘要： Phenolic amides, useful as stabilizers for organic materials such as polyols and polyurethanes, possess the general formula ##STR1## wherein n is 0 to 3, R.sub.1 is alkyl of from 1 to about 6 carbon atoms, R.sub.2 is hydrogen or alkyl of from 1 to about 6 carbon atoms, R.sub.3 is hydrogen or hydrocarbyl of up to about 20 carbon atoms, optionally containing one or more heterocyclic groups, R.sub.4 is hydrocarbyl of up to about 20 carbon atoms, optionally containing one or more heterocyclic groups, or R.sub.3 and R.sub.4 together with the nitrogen atom to which they are bonded are joined together to form a heterocyclic group, optionally containing one or more additional heterocyclic atoms.
