380,169. Resistance coatings and deposits. FOWLER, L. J., 20B, Anerley Park, London, BELL, C. C. M., Corrie Lodge, Virginia Water, Surrey, and CRIT. TALL & CO., Ltd., R., 43, Bloomsbury Square, London. June 23, 1931, No. 18144. [Class 37.] A panel for heating buildings has metal to form the heating resistance sprayed on one side from a spray which moves along a predetermined path. Alternatively the metal may be sprayed on to paper or other light material, which is afterwards attached to the panel. A layer of insulating material may be attached to the back of the panel and behind this may be placed a layer of heat resisting material, or a single layer of material may serve both purposes. Alternatively the panel, after having been sprayed with metal, may be dipped in an insulating liquid which will form a solid insulating film on drying. A sheet of heat insulating material may then be attached to the back of the panel. |
