Abstract: A readily portable tank type pressurized working fluid dispenser is provided. The tank dispenser contains an internal membrane as separator that functions to isolate the working fluid to be dispensed from the pressurizing delivery fluid, e.g., compressed air, that vents the servicing fluid.

Abstract: A radial-type bearing which includes an outer tube-like member rotatable about a center axis and having an inner cylindrical bearing surface. An inner shaft-like member is disposed within the outer rotatable member. The inner member is stationary or non-rotatable and is generally coaxial with the outer rotatable member. A plurality of bearing pads have operative positions radially between the outer and inner members. The bearing pads are pivotally mounted on the stationary inner member for tilting movement in response to rotation of the outer member. The pads have outer bearing surfaces complementary to the inner bearing surface of the outer rotatable member.
