Abstract: An automatic observation system for observing objects such as microorganisms contained in a liquid supplied from a container. A sample of the water is fixed between two glass plates, one of which is movable relative to the other by a plunger. A condensor lens is also carried by the plunger. Light from a continuous-output illuminating source is applied through the condensor lens via an optical fiber.

Abstract: A dry deodorizing apparatus. More particularly, it relates to a dry deodorizing apparatus wherein bad smell components in the gas to be treated is oxidized and removed by ozone and bromine and hydrobromine acid and, in addition, the ozonizing material such as ozone and bromine entrained by the air to be treated is removed with an adsorbent or a decomposing agent so that no secondary environmental pollution due to ozonizing material takes place.

Abstract: A water producing apparatus for extracting water from moisture-laden ambient air including a plurality of circumferentially spaced chambers packed with an adsorbent for adsorbing moisture in the air, a driving mechanism for bringing one or more of the chambers into and out of communication with a first and second desorbing section, a mechanism for passing ambient air through the chambers not in communication with the desorbing section, whereby moisture from the ambient air is adsorbed on the adsorbent and subsequently removed from the adsorbent in each chamber as that chamber is brought into communication with the desorbing sections, a recycling duct connecting the post-desorbing section to the predesorbing section to complete a desorption circuit, a mechanism for circulating air through the circuit to remove water from the adsorbent, a mechanism for heating the air in the circuit, and a mechanism for removing water from the circuit.

Abstract: A water producing apparatus for producing liquid water from a moisture in the ambient air by an adsorbent. Two columns holding the adsorbent are combined with a blower for feeding the air into the column and a condenser for condensing the desorbed steam obtained by heating the adsorbent adsorbing water. The blower and the condenser are commonly used for the two columns so as to minimize pipes and to save a consumption of energy caused by a pressure loss.

Abstract: Sulfur oxides are removed from waste gases containing the same by scrubbing the waste gas with an aqueous scrubbing solution containing the aluminate of sodium, potassium or ammonium and an additional compound selected from the group consisting of aluminum sulfate and alum.
