The liquid barrier filter: total protection against particulate contaminants.

The design, construction, and operation of a new type of filter that eliminates particulate contaminants from a current of gas is described. It has a yield higher than that of any conventional filter or filtration system. It is believed that a liquid barrier filter provides the best possible protection in all cases where not even a small number of toxic particulates can be tolerated in an atmosphere.

The liquid barrier filter--a new concept to eliminate particulate contaminants from gases.

We have explored the possibility of using a continuous liquid phase of high gas permeability as a filter to remove particulate contaminants from a gas stream. The liquid, a non-toxic perfluorocarbon, severs upstream and downstream gas phases completely. It can dissolve great quantities of gases and pass them, by diffusion, along even a slight partial pressure gradient. The liquid phase remains intact in the process: there is no convective transfer of gas. Particulate contaminants will, on impact with the continuous liquid phase, lose their momentum and be stopped; our results promise near ideal efficacy of capture. We suggest that filters based on this principle be developed to protect against highly toxic particulate contaminants in an atmosphere.

[Phospholipids of pulmonary surfactants and lung elasticity].

We discuss the various preparations of substitute pulmonary surfactant that have been proposed for the treatment of Respiratory Distress Syndrome in premature infants. We than submit some experimental results demonstrating that a preparation of phospholipids in an organic solvent can simulate the behavior of the naturally occurring pulmonary surfactant as a monolayer at an air-water interface.
