Abstract: A modular link conveyor system (10) for transporting articles is provided having a plurality of modular link sections (15) providing a support surface for the articles and wherein one or more rollers (30) are positioned in the underside of selected link sections (12) to provide support by rolling on a guide rail (25, 26) of the conveyor system (10). Each link section (12) includes at least one interengaging apex (13) and leg portion (14) having a matching hole (22) and slot (21) for receiving a transverse rod (20) to permit side flexing action. An enclosure (36, 37) for each roller (30) provides protective encapsulation along at least the two sides and substantially around the rolling face to prevent debris build up. Advantageously, at least one roller (30) is mounted in each side link section (13, 14) that also provides a depending arm (28) and transverse tab (29) for lateral guiding action. The link sections (15) are combined to form a composite link and a cover plate provides an extended support surface.

Abstract: A jet nozzle is provided for drilling holes through the earth, such as drainholes around a well. The nozzle may include orifices for discharging fluid to drive the nozzle forward and includes a disk or other device having orifices to produce a swirling motion to fluid in the body of the nozzle. Swirling fluid is discharged from a front orifice and an extension is placed forward of the front orifice to confine the swirling fluid in a radial direction.

Abstract: A jet nozzle (60) is provided for drilling holes through the earth. The nozzle (60) may include orifices (68) for discharging fluid to drive the nozzle forward and includes a disk (70) or other device having orifices (80) to produce a swirling motion to fluid in the body of the nozzle. Swirling fluid is discharged from a front orifice (74) and an extension (76) is placed forward of the front orifice to confine the swirling fluid in a radial direction.
