A shaft sealing apparatus has a housing having axial symmetry about the axis of a shaft disposed therethrough. A seal ring supporting member is slidably disposed about the shaft and is enclosed by the housing. Seal rings are disposed in the seal ring supporting member. A means for moving the seal ring supporting member along the axial direction is provided so that the amount of overlapping area between the seal rings and a sealing portion of the shaft may be controllably varied.

Shaft sealing apparatus using a fluid sealing system

An impingement separator for gas-liquid mixtures, in which at least two separating elements are spaced apart and held upright substantially in parallel to each other so as to provide a passage or passages for liquid-carrying gases. Each element consists of two outer plates bent in a zigzag fashion and spaced in a substantially parallel fashion with horizontal slits formed in the plate portions where the direction of the flow along the plate surfaces is deflected, and a bent inner plate intervening between the outer plates thereby defining liquid passages each facing one of the slits, so that an upward or downward stream or streams of the mixture impinge upon the baffling sections of the outer plates and the liquid is thereby separated out into the liquid passages through the slits and is collected away from the fluid.
