  • Patent number: 4957200
    Abstract: A water distillation apparatus has an outer chamber and an inner chamber suspended within the outer chamber by support arms. The inner chamber suspends a heating element to create steam. Heat is transferred from the inner chamber to the outer chamber, wherein the heated water in the outer chamber is allowed to degassify. Degassification removes unpleasant tasting chemicals from the water before distillation. Openings are provided for air circulation to remove the gasses. A condenser is also suspended by the support arms. The stem exits the inner chamber and goes into the condenser. A fan provides air circulation through the condenser. The outer chamber is not penetrated by any openings, thereby precluding the possibility of any leaks. The support arms bear on the outer chamber walls; the inner chamber is removed from the outer chamber for cleaning simply by lifting up. In one embodiment the outer and inner chambers are made of a ceramic material to better regulate heat transfer.

  • Patent number: 4205750
    Abstract: A container for holding articles and a method for forming this container. The container comprises a support structure having a first bag disposed inside of the support structure and a second bag sealed closely about the outside of the support structure. The first bag is sealed about the articles and bonded to the second bag to hold the container in one piece after the bags have been opened to reach the articles. The method comprises the steps of sealing the first bag about the articles and placing it in the support structure; sealing the second bag about the support structure; shrinking, by heating, the second bag until it forms a closely fitting sealed surface about the support structure; and forming a bond between the first and second bags to hold the container in one piece after it is opened.
