High localized loading, galling, and high torque forces have been generally eliminated or greatly reduced in a two ferrule tube fitting assembly through suitable modification of the rear ferrule so as to redirect the reaction forces acting between the front ferrule and the drive nut. The rear ferrule has a cylindrical interior wall that closely surrounds the tube end and is provided on the interior cylindrical wall with a circumferentially continuous radial recess that is located between the nose and rear wall of the rear ferrule. The rear ferrule also has a radially external wall that is substantially conical and additionally shaped to extend radially outward toward the enlarged diameter portion or flange of the rear ferrule. The rear ferrule further includes a contoured face on the rear driven surface of the ferrule that engages the drive surface of the drive nut.

A suction bell assembly, and an elastomeric liner therefor, are disclosed in which the bell includes a rigid outer shell (10,310) of generally Y-shaped axial cross section with a conical top portion (101) and a cylindrical body portion (106).

The liner also includes an elongated tubular portion 112 spaced normally inwardly from the shell's inner surface, the tubular portion including a resilient annular flange (119) that sealingly engages a shoulder at the lower end of the shell to maintain the liner in an axially stretched and tensioned state. one-way valve means (13,43) is formed integrally with the liner and is disposed at the lower end of the tubular portion below the flange (119). The valve means (13,43) includes a calotte-shaped closure portion (131) having at least one slit (28,438,439) to permit the passage of milk downwardly through the lower end of the liner. In preferred embodiments, each slit (28,438,439) has offset but communicating inner and outer portions (28a,28b,438a,438b, 439a,439b). Means are also disclosed for allowing swivel action of the shell (310) in relation to a connector (32) for detachably connecting the suction bell to a milk-collecting bottle.

A universal block made of concrete designed to be used with different size posts and beams. The pier block is a conical, six-sided structure and includes two concentrically aligned, post-receiving voids designed to receive the ends of a (4x4) or (6x6) inch post. The (6x6) inch void is positioned above the (4x4) inch void. Formed horizontally on the top surface of the pier block are two transversely aligned beam-receiving slots. Each beam-receiving slot includes a narrow and a wide slot longitudinally aligned. The wide slot is positioned above the narrow slot. A vertically aligned drain hole is formed through the pier block from the bottom surface of the (4x4) inch void to the bottom of the pier block, which allows water to drain from the post-receiving voids.

An electromagnet having a conical bore. The conical bore is created by wrapping a conductor around a conically-offset helix. The cross sectional area of the conductor can be varied in order to maintain a desired current carrying capacity along the helix. A single element can be used as the conductor. The conductor can also be created by stacking a series of specially-shaped plates analogous to prior art Bitter-disks.

The pruning manipulator has the characteristics of high automaticity, wide adaptability, energy conservation, environmental protection and the like, and is convenient to popularize and use.

A self contained, hermetically sealed, cigarette shaped nicotine inhaler tube includes a cylindrical wall and formed closed ends. The two or more elements making up the tube are formed and sealed together after forming at a location between the closed ends, capturing a filler within. The filler is in the tube to carry nicotine. The closed ends are recessed from the end of the cylindrical tube and may be truncated conically shaped. The closed ends may be drawn further into the tube using heat and the pressure of a probe. A tool for piercing the ends of the tube includes a supportive cylindrical cavity slightly larger than the tube with a centric spike and a terminal surface in the cavity. The cylindrical wall of the tube is supported by the cavity and the truncated conical shape of the end wall to receive the spike for penetrating the end wall at each end. The terminal surface prevents excessive penetration of the spike.
