Title: High temperature injection and vaporization system for gas chromatography
IPC: G01N1/10
Filed: 1980-10-31
Granted: 1984-03-07
Abstract: Sample injection and vaporization system for gas chromatography is capable of continuous injection of a liquid hydrocarbon sample in the -44 DEG  F. to 1074 DEG  F. boiling range from a closed system such as a flowing liquid stream or high pressure sample bomb. The system overcomes the temperature limitations inherent in the seals of existing sample valves and utilizes a syringe to transport a liquid sample from the sample stream to a hot vaporization zone through which a carrier gas is flowing. Insulating means keep the sample block containing the seals, including one which is contacted by both the carrier gas and sample stream, at a sufficiently low temperature to protect the seals.

Abstract: The fluidic oscillator (14) includes a resonant fluid circuit having a fluid inertance and a dynamic fluid compliance. The inertance is a conduit (4) interconnecting two locations (16a, 16b) of a chamber on each side of a working fluid jet issuing into one end of the chamber (3), the inertance conduit transfers working fluid between the two locations. Through one or more output orifices (10), located at the opposite end of chamber (3), the fluid exits from an exit region (11) which is shaped to facilitate formation of a vortex (the dynamic compliance) from the entering fluid. The flow pattern in chamber (3), specially the vortex in exit region (11) provide flow aspiration on one side and surplus of flow on the opposite side of chamber (3), which effects accelerate and respectively decelerate the fluid in the inertance conduit (4) such as to cause reversal of the vortex after a time delay given by the inertance. The vortex in the exit region will cyclically alternate in velocity and direction of rotation to direct outflow through the output orifice such as to produce a cyclically repetitive side-to-side sweeping stream whose direction is determined, at any instant in time, as a function of the vectorial sum, at the output orifice, of the tangential vortex flow spin velocity vector and the static pressure vector and the dynamic pressure component, both directed radially from the vortex. By changing these parameters and by appropriately configuring the oscillator, sweep angle, oscillation frequency, distribution, outflow velocity, break up into droplets, etc. can be controlled over large ranges.

Abstract: Flow-pressure compensated valves are employed in servo-systems for variable displacement pumps to maintain pump discharge pressure above a minimum pressure level and above the load pressure in a fluid actuator, during the working range of the pumps. In addition, such systems may also include a horsepower limiting valve for ensuring that the rating or predetermined range of horsepower consumption of the pumps is not exceeded. Prior art systems normally continually bleed-off pump discharge or load pressure signals when such horsepower requirements are exceeded to, thus, effect an undesirable horsepower loss in the system. In addition, control systems of this type normally cannot be packaged in modular form and are not adapted for use with pumps of various capacities and sizes. The improved fluid circuit (10) of this invention includes a horsepower limiting arrangement (39) for blocking communication of an actuator pressure signal (P<uA>u) to an actuating chamber (37) of a servo-system (24) for a variable displacement pump (11) and to vent the actuating pressure signal (P<uA>u) in response to a pressure control signal (P<uC>u) which indicates that the pump (11) has exceeded its predetermined range of horsepower consumption.

Granted: 1985-05-29
Abstract: A circuit arrangement for determining the polarity and the magnitude of the load current in a reversible d-c controller includes a bridge circuit comprising two pairs of bridge arms connected to opposite terminals of the voltage supply bus. Each pair of bridge arms connected to the same side of the supply bus form a bypass circuit connected across the load. Two diagonally disposed bridge arms each contain a primary winding of a current transformer having two primary windings connected in opposite winding phase. Load current normally flows through either pair of diagonally disposed bridge arms, but during pauses in the load drive, circulates in one of the two bypass circuits. Electronic switches in each of the bridge arms are controlled so that the load current circulates in successive bypass periods in an alternating pattern in the two bypass circuits. When current flows in a bypass circuit, a phase sensitive voltage is induced in the single secondary of the current transformer. Signals from the electronic switches in one of the bypass circuits are fed via digital logic circuitry to a further electronic switch which causes an operational amplifier to invert pulses from that bypass circuit alone. A pulse train having a polarity corresponding to the polarity of the load current is thereby obtained. In a further embodiment, a sample-and-hold stage for determining the magnitude and polarity of the load current is provided.
