TL;DR: In this paper, an instrument for monitoring the deterioration of articles held in storage in particular, food in cold storage, comprises an input circuit including a temperature sensor and arranged to produce an output proportional to the rate of change at the sensed temperature of a property of the article, the output of the circuit being connected to the input of a linear amplifier.
Abstract: An instrument for monitoring the deterioration of articles held in storage in particular, food in cold storage, comprises an input circuit including a temperature sensor and arranged to produce an output proportional to the rate of change at the sensed temperature of a property of the article, the output of the circuit being connected to the input of a linear amplifier, the output of which is integrated by an integrating device. As shown, a Wheatstone bridge includes a thermistor and is arranged to produce an output which is a quadratic function of the temperature in degrees Celsius, and the integrating device is a mercury coulometer display.

TL;DR: In this paper, a mercury coulometer is provided with a bore having a capillary central portion and end portions which are sufficiently enlarged that the gravitational force acting on the mercury is sufficient to cause it to penetrate the coulometers electrolyte before the electrolyte reaches the electrical contacts.
Abstract: A mercury coulometer is provided with a bore having a capillary central portion and end portions which are sufficiently enlarged that the gravitational force acting on the mercury is sufficient to cause it to penetrate the coulometer electrolyte before the electrolyte reaches the electrical contacts. This feature prevents undesirable chemical reactions between the electrolyte and the contacts and, thus, permits the coulometer to be reused.

TL;DR: In this article, the authors describe a coulometer with a spacing member placed in the electrolyte between the mercury columns to prevent them from being brought into mutual contact, which has a dimension of about 80 - 90 percent of the inner diameter in the direction of the diameter of the bore.
Abstract: A mercury coulometer prepared by sealing in a bored capillary tube a pair of spatially disposed mercury columns with an electrolyte interposed therebetween and drawing out an electrode from said both mercury columns, characterized in that the coulometer has a spacing member placed in the electrolyte between the mercury columns to prevent them from being brought into mutual contact. The inner diameter of the bore is from 0.1 to 2 mm and the spacing member has a dimension of about 80 - 90 percent of the inner diameter of the bore in the direction of the diameter of the bore.
