Abstract
Abstract A novel apparatus cell in which the internal temperature thereof is maintained constant. The apparatus cell embodies a double-walled pot-shaped housing of heat conducting material with the hollow compartment between the double walls being filled with a heat-insulating material. A plate member also formed of a heatconducting material and heated by a locally concentrated heat source serves to close the pot-shaped housing. A pot-shaped cover member also formed of heat conducting material having a collarshaped marginal edge portion is provided, the cover member and particularly the edge portion thereof bearing upon the edge or marginal portion of the plate member. The space between the potshaped cover member and the plate member is at least partially filled with a heat insulating material. The apparatus cell of the instant invention provides a notable advantage in that only one heat source and one thermostat with an associated sensor is required, and, in the preferred inventive embodiment, the heat source comprises a transistor mounted upon the plate member, the transistor being connected in the final stage of a thermostatcontrol amplifier.
