Abstract: ABSTRACT OF THE DISCLOSURE     An annular chamber in a housing has inlets at both ends.  A central segment of the chamber has on its inside wall a groove tapering toward the inside and leading at its base to a centrally located output passageway.  Disposed in the groove and central segment of the chamber is an annular gate ring which has a T-shaped radial cross-section.        There is sufficient clearance between the ring and the walls to permit the ring to move freely a short distance axially within its confinement.  Pressure from one or the other direction of the chamber causes the ring to deform itself against one or the other side of the groove so that the top part of the T-shaped radial cross-section closes off the chamber to the other side.

Abstract: ABSTRACT          A SMOKING PIPE HAVING AN ADJUSTABLE/REMOVABLE FILTER INSERT      The idea behind this invention is to prevent to a great extent the amount of nicotine, tar and moisture absorbed through tobacco smoking from reaching the mouth.  The filtering can be adjusted to let through a minimum amount of nicotine and tar to let the individual appreciate the taste of tobacco without absorbing any appreciable amount of lung damaging nicotine and tar or gradually if desired by decreasing the filtering to let through a greater amount of nicotine to appease the lust of the heavier smoker accustomed to heavier absorbtion of nicotine.      The main purpose of the filtering, however is to allow the individual to smoke as heavily as desired but at the same time preventing the harmful intake of tobacco nicotine and tar from reaching the lungs, thus reducing to a very great extent the harmful resulting damage to the lungs of the addicted pipe smoker.  This method of filtering adjustment will help the heavy smoker to accustom himself through the introduction of a filter adjustment gradually to get used to smoking with a filter.

The planetary gear system is contained in a gear housing detachably secured to the converter housing.  The planetary gear system has an output shaft carrying an output gear meshing with an idler gear which is in turn in meshed relationship with a driven gear of a final drive unit.  The aforesaid gears are of the helical type and are rotatable about parallel axes, with a resulting axial thrust on the output shaft in a direction towards the planetary gear system during rotation of the output gear in the forward direction.  The output shaft is journalled between first and second thrust bearings, with the first thrust bearing being carried on a hollow member detachably fixed to the converter housing and protruding axially therein to support the torque converter stator on a one-way clutch.  The second thrust bearing is radially and axially supported exclusively by the converter housing and is provided with a loading capacity greater than that of said first bearing.
