    摘要： A two-way diverter valve and amplifier, for use with high velocity, high temperature gases in which relatively weak pneumatic control signals are amplified, both as to pressure and flow rate, without the use of mechanically moved parts. A bistable fluid amplifier has its branches coupled to vortex fluid amplifiers which include secondary nozzles through which fluid feeds two conduits each of which terminates in a pneumatic actuator. An additional pair of vortex amplifiers are provided which afford pneumatic pressure relief and prevent overpressure developing in the actuators.

    摘要： Fluidic devices having a fluid inlet, first and second fluid passages having outlets, means for generating a negative pressure in reference to atmospheric pressure at the second fluid passage as fluid passes through the first fluid passage outlet. The first fluid passage outlet is provided with valves to divert the flow of fluid from the first to the second fluid passage.

    摘要： A transfer element for a measuring or control device which is operated by the flow of a pressure medium, in which a jet apparatus of a type known as such is employed for bringing at least two fluid-pressure values into operative association with each other which may be applied by separate conduits so as to serve selectively as a main jet pressure, as a back pressure, or as a suction pressure and may be controlled by a throttle valve in each conduit.

    摘要： A method for implementing a logic operation employs an all fluid-based no-moving part micro-mechanical logic family of microfluidic bubble logic devices that are constructed from complex sequences of microfluidic channels, microfluidic bubble modulators for programming the devices, and microfluidic droplet/bubble memory elements for chemical storage and retrieval. The input is a sequence of bubbles/droplets encoding information, with the output being another sequence of bubbles/droplets. For performing a set of reactions/tasks, the modulators program the device by producing a precisely timed sequence of bubbles/droplets, resulting in a cascade of logic operations within the microfluidic channel sequence, utilizing the generated bubbles as a control. The devices are based on the principle of minimum energy interfaces formed between the two fluid phases enclosed inside precise channel geometries. Various devices, including logic gates, non-volatile bistable memory, shift registers, multiplexers, and ring oscillators have been designed and fabricated.
