Publication number: 20030066616Abstract: A nested rolled paper product is shown in which raised and depressed areas are formed in a sheet. The depressed areas may comprise square shapes, rounded shapes or other geometric shapes that are capable of aligning or nesting in registration when the sheet is rolled to form a reduced diameter rolled product. A high loft through air drying fabric is employed to imprint a high caliper pattern into the sheet in such a way as to nest raised portions, resulting in a more compact product having a minimized roll diameter. Grooves or channels in the sheet are capable of aligning as the sheet is rolled. The resulting rolled product may be toilet tissue, paper towels, or other similar paper products. The final rolled product achieves a minimum roll diameter for a fixed roll length.Type: ApplicationFiled: September 9, 2002Publication date: April 10, 2003Inventors: Richard Wolkowicz, Mark Burazin

By providing a central hub with the plate and sleeve, the central hub provides increased stability and versatility to the sprinkler head. The plate provides additional stability and support to the sleeve, and thus the sprinkler head, rendering the combination better able to operate effectively when high fluid pressures are utilized. The central hub is generally attached to a support structure by some mechanism, such as a leg. The addition of the plate adds versatility by increasing the number and variety of legs that can be used to attach the central hub to the support structure.Type: ApplicationFiled: November 14, 2002Publication date: April 10, 2003Applicant: PNM, Inc.Inventors: Norman J.

Publication number: 20030066663Abstract: The key to this invention of a rotary hand-held tilling and weed removing device is simplicity. The three part design consisting of a 36″ shaft; a “T” shaped handle and two lock collars and only weighing 1.5 pounds makes it a multi purpose garden tool for use with any ⅜ household drill. Easlily attached to the drill chuck, the 2 inch wide rotary arms allow tilling and weed removal in very confined areas and precision control from the shaft handle adds to the ease of use. This simple design does not require blade or tiller bar replacement making it very cost effective. A low carbon, one piece, steel shaft requires no maintenance.Type: ApplicationFiled: September 26, 2001Publication date: April 10, 2003Inventor: Robert McKill

Publication number: 20030066665Abstract: A rock bolter has a turret assembly having a positionable base. The base slidably and rotatably engages a cylindrical member on which a feed track support is affixed. A jack rotatably and slidably engages the cylindrical member, but cannot translate with respect to the base. The jack has a piston connected to the feed track support, and extending or retracting the piston translates the cylindrical member relative to the base to move the feed track support toward and away from a rock surface. A stinger assembly connected to the base engages the rock surface to stabilize the turret assembly. A pivot actuator connected between the base and the jack rotates the jack and the feed track support to selectively place either a drill or a bolt driver in alignment with a desired location on the rock surface.Type: ApplicationFiled: April 17, 2002Publication date: April 10, 2003Inventors: Perry L. Coombs, Ward D. Morrison, Paul R. Bigoney
