    • A mixture of two materials flows through a first measuring station which includes a Venturi meter for obtaining and measuring a pressure difference .DELTA.p that is representative of mass flow rate of the mixture and velocity. The mixture then flows through a second measuring station which includes a temperature differential flowmeter in which a predetermined amount of heat is supplied to heat the flowing mixture and raise its temperature to obtain and measure a corresponding change in temperature that is related to the mean density of the mixture and also the square of the mass flow rate. These values .DELTA.p and .DELTA.t are inputs to computer means which functions to solve a third order polynominal or cubic equation and express that solution in terms of the mixture ratio and flow rates of the individual components and the flow rate of the mixture itself.

    • The quality of heat insulation materials is tested and/or compared in a portable structure in which two heat insulation materials are subjected simultaneously to heat flow from a single common metal-clad heating element and the quantity of heat flow through said material is measured and compared. In one case the portable structure has two conveniently accessible cavities within which equal amounts of such insulation, in flat form, may be placed in contact with corresponding opposite sides of a single common metal-clad planar heat source. In a modification of the invention two tubular insulating materials each of the form and type for insulating pipe, is placed around a metal-clad round heating element and the amount of heat flowing from the heating element and through a corresponding one of said materials is measured and compared using individual thermopiles secured to the outer surface of each material.

    • Disclosed is a device for simultaneously heating and cooling adjacent food portions. A first module defining a first hollow chamber is formed into a substantially planar surface for supporting the food portion to be cooled. The first chamber contains a vaporizable substance in equilibrium with vapor. A second module defining a second hollow chamber is likwise formed into a substantially planar surface for supporting the food portion to be heated. The second chamber contains a sorbent and is evacuated. The chambers are fluidly interconnected by a conduit having a normally closed valve to prevent egress of vapor from the first chamber. In use, the valve is open, allowing vapor from the first chamber to flow into the evacuated second chamber. The resulting drop in pressure allows the vaporizable substance in the first chamber to change phase into vapor, thereby cooling the first chamber and its associated food portion. Moisture in the vapor entering the second chamber is absorbed by the sorbent, which evolves chemical reaction heat, thereby heating the second chamber and its associated food portion. The first and second modules of the present invention may be conveniently placed in adjoining pockets of a foam container for containing the cold and hot portions of a sandwich or other fast food.
    • 公开了一种用于同时加热和冷却相邻食品部分的装置。 限定第一中空室的第一模块被形成为用于支撑要冷却的食物部分的基本平坦的表面。 第一个室含有与蒸气平衡的可蒸发物质。 限定第二中空室的第二模块似乎形成为用于支撑待加热的食物部分的基本平坦的表面。 第二个室含有吸附剂并被抽真空。 这些室通过具有常闭阀门的管道流体地互连,以防止蒸气从第一室排出。 在使用中,阀是打开的,允许来自第一室的蒸汽流入抽空的第二室。 所得到的压力下降允许第一室中的可汽化物质将相变为蒸气,从而冷却第一室及其相关食品部分。 进入第二室的蒸气中的水分被吸附剂吸收,吸附剂会释放化学反应热,从而加热第二室及其相关食品部分。 本发明的第一和第二模块可以方便地放置在用于容纳夹心或其它快餐的冷热部分的泡沫容器的相邻袋中。

    • A disposable heating device is disclosed that includes a container having a first zone, a second zone and a third zone. A fuel is contained within the first zone and an oxidizing agent contained within the second zone. A first frangible separator disposed between the first zone and the second zone. The first frangible separator is manually operable to provide communication between the first zone and the second zone thereby defining a reaction zone. A second frangible separator is responsive to an exothermic chemical reaction within the reaction chamber. The second frangible separator is operable to provide communication between the reaction chamber and the third zone. Communication between the first zone and the second zone allows mixing of the fuel and the oxidizing agent to initiate an exothermic chemical reaction and an environmental parameter associated with the exothermic chemical reaction operates the second frangible separator.
