Abstract: Self cooling and self heating beverage containers utilizing water, the boiling point of which has been lowered by a vacuum as the working cooling fluid. A dessicant in a separate container sorbs the vapor generated by the boiling water. The sorption of vapor by the dessicant raises the temperature of the dessicant and limits its vapor sorbing abilities. Provision is made to lower the temperature of the dessicant chamber. In one version of the invention the dessicant chamber is constructed of good heat conducting material, and is immersed in a water bath, to lower the temperature of the dessicant chamber. Alternatively, the outside surfaces of the dessicant chamber are coated with a wick like material. Pre-packaged water is provided to wet the coated dessicant chamber surfaces. The dessicant chamber is then cooled by natural evaporation of the water. In a related improvement, a beverage to be heated is used instead of water as the cooling medium.

Abstract: A flow selector and regulator for use in an I.V. administration arrangement which includes the capability of establishing the flow rate without calibration at the time of use and then automatically maintaining that flow rate regardless of changes in fluid pressure in either or both of upstream or downstream of the regulator. The regulator utilizes a diaphragm which is not subject to stretching or material stress prior to use to control an orifice. The regulator is capable of being calibrated at the time of manufacturer directly in terms of flow rate, something which is not possible in prior such devices. The diaphragm is clamped at the rim and has an arcuate torus facing the inlet and a bulbous central section which controls flow through an outlet orifice. Liquid bypasses the diaphragm through the rim. Other embodiments incorporate the regulator into a drip chamber and reduces the number of parts of the regulator to three members which can be snapped together.
