Abstract: An acoustic transmitter is employed in a borehole logging tool for generating low frequency acoustic energy waves. A tube of piezoelectric material is sealed at both ends and filled with liquid. A pliable boot surrounds such piezoelectric tube. At least one passageway communicates the inside of the piezoelectric tube with the inner surface of the boot.

Abstract: An empty container detector for use with a drip chamber comprises a photoelectric transducer associated with the fluid container which generates a variable control signal to alternately indicate whether the light path of the photoelectric transducer is being refracted by a fluid. A second photoelectric transducer is associated with the fluid container above the fluid level in the container to establish a reference signal which is modulated by drops falling into the container and which has a component corresponding to the condition wherein the light path is not refracted or attenuated by the presence of a fluid. Electrical means are provided to connect the first photoelectric transducer to the second photoelectric transducer to linearize and normalize the reference signal with the control signal. A comparator is associated with the photoelectric transducers and connected to an alarm which indicates when the control signal is substantially equivalent to the reference signal and thus indicating the lowering of the fluid level below the light path of the first photoelectric transducer. Another comparator is associated with the photoelectric transducers to count modulations in the reference signal as indicative of the drops entering the container.

Abstract: An amplifier includes first and second transistors having emitters connected to a first current source, feedback from the second transistor collector to its base being supplied through a base-emitter path of a first Darlington pair in series with a first diode. A second current source is connected to the first Darlington pair emitter. Third and fourth transistors have emitters connected to a third current source with feedback supplied from the fourth transistor collector to its base through a second Darlington pair and a second diode. The second Darlington pair emitter is connected to a fourth current source and resistively coupled to the first Darlington pair emitter. Constant currents are supplied to the second and fourth transistor collectors and an input voltage across the first and third transistor bases controls allocation of current between the first and second Darlington pair emitter-collector paths to produce a differential output current proportional to the input voltage when both Darlington pairs are on. When the input voltage is highly negative, the first Darlington pair turns off and a biasing circuit reverse biases the first diode to prevent the second transistor from saturating and substantially discharging capacitance at the base of the first Darlington pair. Thus, the first Darlington pair can rapidly turn on when the input voltage is subsequently driven more positive. When the input voltage is highly positive, another biasing circuit reverse biases the second diode to prevent the fourth transistor from saturating.
