Shelby Tube Sampler. Utilized in the 'Standard Practice for Thin-Walled Tube Sampling of Soils for Geotechnical Purposes' (ASTM D 1587 [5]). This sampler consists of a thin-walled tube with a cutting edge at the toe. A sampler head attaches the tube to the drill rod, and contains a check valve and pressure vents.
The test uses a thick-walled sampling tube, with an outside diameter of 5.01 cm (2 in) and an inside diameter of 3.5 cm (1.375 in), and a length of at least 60 cm (24 in). The sampling tube is driven into the ground at the bottom of a borehole by blows from a hammer with a mass of 63.5 kg (140 lb) falling a distance of 75 cm (30 in). The sample ...
A thin walled beam is a type of beam (structure) that does not have a solid cross sectional area. The cross section of thin walled beams is made up from thin panels connected together. Typical closed sections include round, square, and rectangular tubes. Open sections include I-beams, T-beams, L-beams, and so on.
Drill pipe, is hollow, thin-walled, steel or aluminium alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus. It comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2).

Such wet liners had been used in high performance engines for many years, but this was an early example of them for a low-cost, mass-production engine. Particularly with the advanced grinding techniques necessary to make such a thin-walled tube with good concentricity and surface finish, other manufacturers saw them as over-complex.
