摘要： A nitrogen-containing ester of a carboxy-containing interpolymer which is particularly useful as a pour point depressant is disclosed. The interpolymer has a reduced specific viscosity of from about 0.05 to about 1 and is derived from at least two monomers, one of said monomers being a low molecular weight aliphatic olefin or styrene and the other of said monomers being an alpha, beta-unsaturated aliphatic acid, anhydride or ester thereof. The nitrogen-containing ester is substantially free of titratable acidity and is characterized by the presence within its polymeric structure of at least one of each of the following groups which are derived from the carboxy groups of said interpolymer:(A) a carboxylic ester group, said carboxylic ester group having at least eight aliphatic carbon atoms in the ester radical, and(B) a carbonyl-polyamino group derived from a polyamino compound having one primary or secondary amino group and at least one monofunctional amino group,wherein the molar ratio of carboxy groups of said interpolymer esterified to provide (A) to carboxy groups of said interpolymer neutralized to provide (B) is in the range of about 85:15 to about 99:1. Lubricant compositions and additive concentrates comprising the foregoing nitrogen-containing ester as well as a process for making such ester are also disclosed.

摘要： The therapeutic laser apparatus includes at least two wands connected to a controller and radiation source via fiber optic cables. The controller and source include at least two infrared wavelength solid-state diode (“SSD”) lasers and at least two visible wavelength SSD aiming lasers. The apparatus further includes a combiner configured to maintain the electromagnetic radiation from one infrared SSD laser coincident with one visible light SSD aiming laser. In the method according to the invention, the visible light SSD aiming laser is used as a pointer so that an operator can position the wands adjacent to the skin of a mammal whereby the beams of infrared treatment lasers intersect at a region inside the body of the mammal.
