Abstract: 634,285. Hygrometers; thermometers. STEWART, Sir F. C. March 16, 1948, No. 7832. [Class 97 (iii)] An instrument for relating or indicating the dew points of the atmosphere and of a space to be ventilated comprises a casing 1 having two compartments respectively connectible to the atmosphere and to the space, a temperaturesensitive element, e.g. a bimetallic strip 6a, 6b and a humidity-sensitive element 7a, 7b linked to one another in each of the compartments, an indicator linked to the elements in one compartment, an indicator co-related to the first indicator and linked to the elements in the other compartment and a scale 13 cooperative with both indicators. Preferably, the indicators are housed in a third compartment of the housing located between the two compartments containing the sensitive elements, the first indicator being in the form of a pointer 10 operated by linkage 8a, 9a under the control of a spring 12a, and the second indicator being constituted by a dial 11 mounted coaxially with the pointer 10 and operated by linkage 8b, 9b under the control of a spring 12b. The third compartment is in communication with the other two compartments and may be connected by a pipe 4 with a source of suction which permits air to be drawn from the atmosphere and from the space to be ventilated, e.g. a ship's cargo-hold into their respective compartments and associated sensitive elements. The series relationship of the temperature and humidity-sensitive elements in each compartment and the approximate linear relationship between humidity, dry-bulb temperature and dew-point enable the pointer 10 and a pointer marked on the dial 11 to indicate on the scale 13 the dew-points of the atmosphere and the cargo-space respectively. The dial may be divided into areas marked " ventilation " and " no-ventilation " as shown indicating when it is permissible to ventilate the cargo-space with atmospheric air without condensation of moisture in the hold, i.e. when the atmospheric dew-point is lower than the hold dew-point. A cock 14 enables a common source of air supply to be connected to both compartments for calibration purposes.
