Abstract

353,275. Thermostats. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. Aug. 11, 1930, No. 24062. Convention date, Feb. 27. [Class 64 (ii).] A thermostat, more particularly for piezoelectric crystals, comprises a thick-walled container of good heat conductivity, surrounded by a heating coil which is enclosed by a sleeve of material of good heat-conductivity so that heat generated by the coil may be rapidly dissipated outwards. A copper block K, is provided with a space Q for the crystal, closed by a .stopper V, and is surrounded by a heating coil H controlled by a thermometer T. The coil H is surrounded by a sleeve K2 of material of good conductivity, and loss of heat above and below the block K1 is prevented by insulating layers F, J.
