Abstract: There is described a method for heating a sample material in a sample holder, the method comprising receiving the sample holder in a heating chamber of a heating system, the sample holder having at least one sample recipient with the sample material therein; dynamically forming an individual mini microwave cavity around the sample recipient; and applying microwaves generated by at least one microwave generator directly to the sample.

Abstract: There is described an automated heating system for heating a sample contained in a sample holder, comprising: a heating chamber having at least one opening and adapted to receive the sample holder; a microwave generator in microwave transfer communication with the heating chamber; a conveyor extending into the heating chamber and adapted to receive and transport the sample holder into and out of the heating chamber; at least one microwave barrier movable between an open position to allow access to the heating chamber and a closed position to prevent microwaves from leaking out of the heating chamber when the microwave generator is activated; and a control unit for controlling the microwave generator and the conveyor.

Abstract: An electronic hydrometer for determining the density of a liquid, the hydrometer comprising a housing having a liquid receiving chamber and means to insert a liquid of which the density is to be determined in the chamber. A float having a known weight is disposed in the chamber. A connecting shaft is secured to the float and retained for guided displacement along its longitudinal axis in response to introduction of a predetermined quantity of liquid in the chamber. A sensor is associated with a shaft for detecting a reference position of the shaft. A permanent magnet is mounted in proximity of the shaft and has a magnetic core and a displaceable coil about the core. The coil is secured to the shaft. An electronic circuit means automatically adjusts the value of a current flowing in the coil to displace the coil and the shaft relative to the reference position. The value of the adjusted current is calibrated by the circuit to generate an output signal indicative of the density of the liquid in the chamber.
