Abstract: A delayed actuator mechanism with visco-elastic timer is provided including a support section and an actuator section mounted to the support section. A compression spring biases the actuator section in a first state and permits the actuator section to be selectively switched to a second state. In that state a cocked torsion spring urges a detent carried by the actuator into engagement with a shoulder of the support section to restrain the actuator section in the second state. A visco-elastic delay mechanism gradually relaxes the torsion spring until the compression spring overcomes the detent shoulder restraint to abruptly switch the actuator section to the first state.

Abstract: A visco-elastic actuator mechanism including a support section and an actuator section. A visco-elastic adhesive is mounted to one of the sections and is engageable by the other of the sections to hold the actuator in a first state. A spring urges apart one of the sections relative to the other until the actuator is abruptly switched to a second state.

Abstract: A calibration system for a temperature sensing probe in an electronic thermometer, including: a reference temperature element having a characteristic that varies as a function of temperature; a reference temperature sensing circuit, responsive to the reference element, for providing a reference signal representative of the temperature sensed by the reference element; a probe temperature sensing circuit responsive to the probe for providing a probe signal representative of the temperature sensed by the probe; means for releasably interconnecting the probe and the probe temperature sensing circuit; and comparator means for comparing the probe signal representative of the temperature sensed by the probe and the reference signal representative of the temperature sensed by the reference element; the probe temperature sensing circuit being responsive to the comparator means for adjusting the probe signal representative of the temperature sensed by the probe to match the reference signal representative of the temper

Abstract: A piezoelectric circuit breaker including: a line terminal and a load terminal; contact means interconnected between the terminals; means responsive to an increase in load current between the terminals for generating a voltage indicative of an overload current; and piezoelectric bender means responsive to the voltage for deflecting and opening the contact means.

Abstract: In an electron gun assembly comprising at least one oxide coated cathode and a G1 grid, a method of spacing the cathode a predetermined distance from the G1 grid includes the following steps. First, the cathode oxide coating is moistened with water causing it to become electrically conductive. Next an ohmmeter is connected to indicate the electrical resistance between the electrically conductive oxide coating and the G1 grid. The spacing between the cathode and the G1 grid is then reduced until the ohmmeter indicates that there is electrical conductivity therebetween. At this point there is zero spacing between the cathode and the G1 grid. The spacing between the cathode and the G1 grid is then increased by an amount equal to the predetermined spacing. The cathode is then permanently fixed at the predetermined spacing with respect to the G1 grid.
