Abstract: An apparatus for placing auger type anchors into the earth includes a machine frame that supports an elongated housing. The housing has upper and lower end portions. An anchor holder is positioned at the lower end of a tubular member rotatably mounted in the housing for holding an anchor and rotating it during placement. A plurality of drive wheels carried by the frame transport the housing between upper and lower positions. The wheels are loaded with adjustable compression springs so that extensive pressure can be applied from the drive wheels to the housing for gripping and driving the housing during insertion. A gear train interconnects the driving wheels so that all of the driving wheels rotate at the same rotational speed.

Abstract: An apparatus for drilling boreholes into the earth includes a mobile carrier with a frame that supports an elongated housing. The housing has upper and lower end portions. An drill pipe section holder is positioned at the lower end of a tubular member rotatably mounted in the housing for holding a drill pipe section and rotating it during placement. A plurality of drive wheels carried by the frame transport the housing between upper and lower positions. The wheels are loaded with adjustable compression springs so that extensive pressure can be applied from the drive wheels to the housing for gripping and driving the housing during insertion. A gear train interconnects the driving wheels so that all of the driving wheels rotate at the same rotational speed. Water is supplied to the housing via a bore that communicates with openings and a bore of the tubular member. The tubular member bore conveys the water to multiple sections of drill pipe (i.e.

Abstract: An apparatus for placing geophones beneath the surface of the earth includes a machine frame that supports an elongated probe rod. The probe rod is dimensioned to reach a selected subterranean earth layer. The rod has upper and lower end portions. A geophone holder is positioned at the lower end of the rod for holding a geophone and its cable. A plurality of drive wheels carried by the frame transport the rod between the upper and lower positions. The drive rollers include at least an opposed pair of upper wheels and an opposed pair of lower wheels. The wheels are loaded with an adjustable spring pusher so that extensive pressure can be applied from the drive wheels to the pipe for gripping and driving the pipe even when muddy. A gear train interconnects all of the driving wheels so that all of the wheels rotate at the same rotational speed. A gear train preferably includes six gears including a pair of upper gears, a pair of lower gears, and a pair of intermediate drive gears.

Abstract: A segmented barrel extruder device for extrusion and having a plurality of segments enclosing an extruder barrel aligned on an axis. The segments include axially perpendicular rectangular end flanges having exposed sides and a central portion for housing an extruder barrel. The flanges have aligned straight line paths for fluid flow in a plane perpendicular to the axis. Accordingly, the paths each intersect two exposed sides without intersecting the central portion. The segments also include an extruder bore between the flanges. The segments have a housing having straight axial channels which are connected to the paths in the flanges to conduct fluid from points along one path in each path to of points along a corresponding path. The extruder bore also includes a centered portion aligned with the flange central portion and a radial feeder device. The radial feeder device includes a seal and a mount which is adapted to mount the seal without sealing force on the bore.

There is also provided an extruder barrel insert sized to fit in the centered portion of the barrel having a key for preventing rotational movement.

Abstract: A segmented extruder device for extrusion along a longitudinal axis. The device has a plurality of segments enclosing a barrel aligned on the axis. The segments each include a pair of axially perpendicular end flanges for each segment. Each of the flanges have exposed sides and a central portion for housing an extruder barrel. The flanges have a plurality of straight line paths for fluid flow into and out of the flanges in a plane perpendicular to the axis. A port is provided to give access to each straight line path from at least one side of each flange. A housing portion is placed between each of the pair of flanges for housing the extruder barrel. The housing has a plurality of straight axial channels operably connecting the flanges to conduct fluid along the barrel from each of the straight line paths in one flange to a corresponding straight line path in the other flange. Finally, the device includes an inlet and an outlet for introducing fluid into and removing fluid from selective paths and channels.
