A flush-diaphragm pickup and a feedback stabilized carrier amplifier are among the features incorporated into an improved variable-reluctance transducer. This low impedance device responds to steady-state as well as transient pressures.
Elimination of starting difficulties in SCR inverters is accomplished by the addition of two taps of the output winding of the inverter. On starting or under transient loads, the two additional taps deliver power through diodes without requiring quenching of SCR currents in excess of normal starting load.
Experimental effect of gas flow transients on heat emission of burning liquid drops in a rocket combustor
A circuit, in a wide bandwidth mode, overcomes transient-producing capacitance switching by maintaining an equivalent voltage at all times. Bandwidth switching may be done at any time, and integrity of the loop lock is maintained.
Adjustment of separated flow regions with respect to pressure, mass, and heat transfer to transient external flow
Supported dual-mode burst diaphragm protects vacuum vessels from transient internal pressures. It forms the interface between the vacuum in the vessel and an external pressure.

Transient pressure transducer evaluation and improvement of laboratory electric equipment and techniques
Transient heat transfer through thin circular pipe due to unsteady flow
Optimum correction of distorted thrust transient measurements
Transient measurement of thermal diffusivity of refractory materials at high temperature
Transient concentration polarization in natural convection electrolysis
Decay function of transient conductivity for lightly doped semiconductors and slightly ionized plasmas
Suppression of relay coil voltage transients by bifilar winding of relay coil
Computer program evaluates heat transfer modes and calculates either the transient or steady-state temperature distributions throughout an object of complex shape when heat sources are applied to specified points on the object. It uses an electrothermal model to simulate the conductance, heat capacity, and temperature potential of the object.
