Abstract
685,229. Non-metal resistances; temperature variable resistances. WESTERN ELECTRIC CO., Inc. June 23, 1950 [June 28, 1949], No. 15735/50. Class 37. A thermistor, Fig. 5, comprises a layer of sintered particles of selected thermistor material 14, for example one or more of the oxides of manganese, nickel, cobalt, copper, iron or zinc, sandwiched between two-part electrodes with one part of each electrode an inner layer 19 of a sintered mixture of particles of the selected thermistor material 14 and particles of a noble metal, for example platinum or palladium and the other part of each electrode an outer layer 20 consisting wholly of sintered particles of a noble metal, for example platinum or palladium. In Fig. 4 a thermistor is shown associated with a thermal sink and this thermistor is similar to the one in Fig. 5 except that the outer all-metal electrode layers are omitted. As indicated a platinum ribbon 16 welded to the platinumthermistor material electrode layer 15 supports the thermistor above a slot 18 in a block of copper 17 which constitutes the thermal sink. The manufacture of the thermistor shown in Figs. 4 and 5 involves the use of temporary plastic binders in both the thermistor and electrode material layers and the driving out of these binders simultaneously by heat treatment prior to sintering. The binder and solvent of the thermistor and electrode materials may be identical, for example the binder for both with a selected volatile solvent may be isobutyl methacrylate, polyvinyl buteral, polyvinyl chloride, or cellulose acetate (a plasticizer may be added in the case of a polymerized methacrylate). It is, however, stated to be preferable to employ a binder and solvent for one which is mutually insoluble with that of the other; this may be accomplished by using any of the binders given above for the thermistor material and using for the electrode material poloxyethylene with water as a solvent or copolymer butadiene styrene with cyclohexane as a solvent. The thermistor shown in Fig. 5 may be made from composite thermistor-electrode material which reading on to Fig. 5 comprised in the green stage outer electrode layers 20 formed from a paste of platinum black, isobutyl methacrylate and a volatile solvent, inner electrode layers 19 formed from a paste of 75 per cent by volume of platinum black and 25 per cent by volume of a thermistor material mixed with a copolymer butadiene styrene and cyclohexane as a solvent, and a thermistor material layer 14 formed from a paste of thermistor material, isobutyl methacrylate and a volatile solvent. The Specification includes a chart; Fig. 1 (not shown), which particularizes the various production stages..
