Patent number: 7885851Abstract: A method for determining an optimal number of lottery retailers is disclosed. The optimal number of lottery retailers for a region can be determined based households of the same segmentations purchasing lottery products similarly, and there is a strong correlation between lottery agent density (population/retailers) and per capita lottery sales. The lottery agent density (LAD) necessary to produce high per capita sales can be identified and applied to all markets of that household segmentation.Type: GrantFiled: November 17, 2006Date of Patent: February 8, 2011Assignee: Scientific Games International, Inc.Inventors: John Hurt, Michael Dax Flinn, Jim O'Brien

Patent number: 4487274Abstract: A rock drill is provided including a flap valve allowing high cutting speed operation over a range of compressed air pressures. The rock drill further includes a wear sleeve secured to a back head with a chuck to the opposite side, an inner cylinder within the wear sleeve, a valve seat at the inner end of the cylinder with a valve stem extending into the cylinder, and a piston within the cylinder reciprocable from one position where the valve stem engages a bore in the piston to a position where the stem enters a bearing in the cylinder to strike a drill bit held by the chuck. The ratio of the piston head area to its bore area is 9.9/9.95 to 1. The ratio of the piston head length to the stem length is 1.5/1.52 to 1. The ratio of piston head diameter to stem diameter is 1.4/1.43 to 1 and the ratio of piston stem length to the length of stem within the bearing at the point at which the piston strikes the bit is 1.4/1.45 to 1.Type: GrantFiled: July 21, 1982Date of Patent: December 11, 1984Assignee: Weaver & Hurt LimitedInventor: John A.
