    Abstract: An improved ionization type smoke detector which is specifically designed to be independent of variations in atmospheric pressure and to be highly sensitive to smoke. A number of factors are involved in choosing optimum design parameters for an ionization smoke detector which has minimum sensitivity to pressure and which also has a maximum sensitivity to the presence of smoke. Several equations are described which aid in the design.

    Abstract: A continuous flow method and apparatus for the determination of glucose in a biological fluid by the oxygen depletion method is provided. The biological fluid sample, along with a carrier solution, are combined and introduced into a chamber containing gel-immobilized glucose oxidase. The mixture is caused to flow sequentially through the immobilized glucose oxidase and a connecting passage the outlet of which is disposed such that the fluid impinges on an oxygen-permeable membrane where the oxygen diffusing therethrough drains sensed electrochemically. The effluent solution drians and the system is regenerated by flushing with a quantity of the reagent solution. The glucose oxidase is immobilized in a manner which allows many tests to be run without any significant loss of enzyme thereby accomplishing a considerable cost reduction in the tests.

    Abstract: A viscosimeter and a densitometer are provided through use of a transducer or transducers to provide energy transductions and for providing vibratory energy. In this way, either shear wave energy or longitudinal wave energy or both can be imparted to the surrounding fluid. Indications from the transducer or transducers provide representations of either the fluid viscosity or the fluid density.
