Abstract
Abstract A device for regulating the temperature of a container which is surrounded by a good heat-conducting medium attached to an electro-thermic element, and arranged such that the container can be removed from one side of the device and also inserted into the device on the same side. Also, between the outer surface on one side of the device and the good heat-conducting medium the device has heat insulating material, which material has at least one perforation permitting a container to be inserted into and removed from the good heat-conducting medium.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
132 words
A device for regulating the temperature of material in a container which is, in turn, surrounded by a good heat-conducting medium attached to an electro-thermic element and arranged such that the container can be removed from one side of the device and also inserted into the device on the same side, characterized in that between the outwardly directed surface of said side of the device and the good heat-conducting medium an insulation of a predetermined thickness is provided, said insulation having at least one perforation permitting a container to be inserted into and removed from the good heat-conducting medium, and that a gripper is provided, the length of which is at least the same as the thickness of the insulation and by means of which the container can be removed and/or inserted.
Claim 2
Independent Claim
132 words
A device for regulating the temperature of material in a container which is, in turn, surrounded by a good heat-conducting medium attached to an electro-thermic element and arranged such that the container can be removed from one side of the device and also inserted into the device on the same side, characterized in that between the outwardly directed surface of said side of the device and the good heat-conducting medium an insulation of a predetermined thickness is provided, said insulation having at least one perforation permitting a container to be inserted into and removed from the good heat-conducting medium, and that a gripper is provided, the length of which is at least the same as the thickness of the insulation and by means of which the container can be removed and/or inserted.
