Abstract: Apparatus is disclosed which provides an improved means of measuring the operating characteristics of a multiplicity of thermocouple reference junctions. The apparatus allows accurate sensing of temperature through use of both a measurement and reference junction thermocouple arrangement. The reference junction thermocouples are collectively encased and surrounded by an insulating medium which on one side abuts a metal plate serving as a heat sink of appreciable mass. The operating temperature of the heat sink is then monitored by a temperature sensitive resistor. Voltage drop across the resistor is convertible into a measure of system calibration.

A pneumatic cylinder is connected with the plunger at the opposite end of the bore for reciprocating the plunger in the bore to project the recess into the vessel to receive a sample of liquid therein, and to then move the recess from the vessel and to an intermediate point in the bore whereat a housing outlet port receives the sample.

Abstract: A thin plate-like rotor is mounted on a hub which in turn is attached to the shaft of a motor which drives the rotor at a predetermined rotational speed about a spin axes. A framework is provided for mounting the motor. The rotor has a damping face and an opposite signal face. A damping plate is mounted on the hub in close spaced relation with the damping face. A spring member is disposed between the hub and the rotor so that the rotor is free to move in restrained rotational fashion about one diameter of the rotor. Surrounding air is pumped through the space between the damping face and the damping plate to provide damping of the motion of the rotor about the one diameter. Pickoffs are mounted in the framework in close spaced relation to the signal face of the rotor. The pickoffs provide output indicative of the spacing between the signal face and the pickoffs which corresponds to angular velocity inputs about the separate axes disposed orthogonally with the spin axes.
