Abstract: A facility for selecting advertising outlets on which to place advertising messages for an advertiser is described. For each of a first group of advertising outlets, the facility assesses the rate at which visitors to the advertiser also visit the advertising outlet. The facility selects an advertising outlet among the first group having the highest assessed rate. For each of a second group of advertising outlets, the facility assesses the tendency of a high-performing advertising outlet to drive its visitors to the advertising outlet among the second group of advertising outlets. The facility selects an advertising outlet among the second group to which the high-performing advertising outlet has the greatest assessed tendency to drive its visitors.

Abstract: A method of forming a joint between a workable tubing of a first diameter and a tubing of a second, larger diameter proceeds with the formation of a bell in the end of the workable tubing. The workable tubing is clamped, with the end of the workable tubing located in a cavity of a die. A mandrel is spun, and inserted into the end of the workable tubing. The mandrel has a pilot tip, and a forming land. The forming land expands the end of the workable tubing as the mandrel is spun. A bell is formed in the workable tubing, which has an outer diameter substantially equal to the inner diameter of the second, larger tubing. The workable tubing is freed from the clamp and die, and the bell is inserted into the second, larger tubing. The two tubes are brazed, without need for a bushing.
