  • Patent number: 5347830
    Abstract: An adsorption cooling apparatus includes a hermetically sealed cylindrical capsule that contains a first thermal medium, a moisture absorber on its first side and an adsorbent on its second side. The capsule reciprocatively moves and slidably contacts with a cooling vessel containing a low temperature thermal medium on the first side and with a heating vessel containing a high temperature thermal medium on the second side. The capsule is cooled by an external airflow when it is moved to the cooling vessel, so that the first thermal medium absorbed in the moisture absorber evaporates and the low temperature thermal medium in the cooling vessel is cooled because of the latent heat of evaporation of the first thermal medium. The so cooled low temperature thermal medium is utilized for cooling the object to be cooled. The first thermal medium having evaporated from the moisture absorber is adsorbed by the adsorbent.

  • Patent number: 5347844
    Abstract: The invention concerns a process and a device for splitless vaporizing injection of samples into equipments of gas chromatographic analysis.The technique is applied specially when liquid samples generate volumes of vapors which cannot be housed inside the vaporizing chamber.Inside the vaporisation chamber, kept at high temperature, evaporation of the sample solvent forms a cool zone where the solutes are retained while the solvent vapors expand out of the vaporizing chamber and leave the injector. The sample liquid is kept in place within the vaporization chamber by suitable obstacles or by a packing material. At the end of solvent evaporation, i.e. when cooling ceases, the injection zone returns to the regulated injector temperature and the compounds to be analysed are transferred to the column by the carrier gas.

  • Patent number: 5347860
    Abstract: This invention provides a device and method for measurement of the actual on-bottom time of a sampling otter trawl used for benthic sampling. The device uses passive measurement of the actual on-bottom time without cables and wires connected to the ship, and is small enough to be mounted on a standard otter trawl door without affecting its net-towing function. The apparatus consists of a sealed bottom contacting and counting sensor which totalizes and displays the accumulated on-bottom time. Power is supplied from a self-contained battery which may be automatically recharged by a solar cell. In operation, a flexible trigger arm is mounted so as to extend below the runner on the bottom edge of the trawl door. When bottom contact is first made, the trigger arm bends and mechanically causes a magnet to move sufficiently close to actuate a magnetic switch inside a transparent electronic data module. An electronic counter inside the module will count minutes and seconds as long as the magnetic switch is closed.

An air pump pressurizes the probe, increasing the pressure up to the point at which the liquid is completely displaced from the probe and bubbles of air evolve from the end of the probe. At that point the pressure is proportional to the height of the liquid in the tank. A pneumatic connection from the probe to the reporting unit refers the pressure to a piezoresistive pressure transducer working in concert with an electronic process controller. The controller produces a voltage output which is reported as a digital numeric readout, reading in volts or in programmed engineering units. Jittery variations in the least significant figure of the numeric readout, which are associated with the evolution of air bubbles from the end of the probe, are eliminated by adding an air tank buffer to the pneumatic system.

  • Patent number: 5347864
    Abstract: An improved liquid level measuring apparatus having a plurality of spaced reed switches having a microprocessor attached to the liquid level measuring sensor apparatus. The switches are wired together in parallel and in sets and are addressed by a shift register for providing a parallel to serial shift of the switch status position to the microprocessor. This allows a reduction in the number of conductors existing the sensor and providing an output signal indicating the vertical position of a float relative to the switches. A microprocessor control notes any inoperative switches, disregards the reading of the inoperative switches in calculating liquid level, and provides stored information to the measurement process for compensating for defective switches.

  • Patent number: 5347867
    Abstract: An accelerometer implementing a capacitive transducer, including circuitry for reducing the effective loading capacitance on a movable vane. The capacitive transducer includes a pair of shields, including an inner shield driven by the output of a unity gain amplifier which is coupled to the movable vane, and a second outer grounded shield isolated from and encompassing both the driven shield and the capacitive transducer. Thus, the accelerometer reduces both the effective parasitic loading capacitance by taking advantage of the well-known Miller theorem, while implementing a second grounded shield without affecting the parasitic loading capacitance to reduce EMI. A more linear capacitive based accelerometer is realized which can be practically implemented in vehicles, including vehicle performance analyzers used in automobiles for detecting changes in G-forces experienced during acceleration and deceleration of the vehicle.

  • Patent number: 5347874
    Abstract: A mass flowmeter has a flow tube inserted within the confines of a conduit containing a material flow. Mass flow information is derived for the material flow within the conduit by generating mass flow information for the material flowing within the smaller flow tube positioned within the conduit and then by adjusting the calculations for the flow tube to represent mass flow information for the conduit. In accordance with a first embodiment of the invention, a pressurized cover is positioned around the flow tube to isolate the exterior surface of the flow tube from the material in the conduit. The space between the exterior of the flow tube and the cover is pressurized to a pressure equal to that of the material in the conduit. Both sides of the flow tube walls are at the same pressure so that a flow tube comprised of thinner and more flexible material may be used.

  • Patent number: 5347876
    Abstract: A temperature time-of-flight (TOF) sensor is combined with a nozzle of known flow area to create a TOF flowmeter. The TOF measured by the flow sensor provides a measure of gas volumetric flow rate. A TOF sensor has of a pulse heated wire and a single temperature sensor downstream of the wire. This single temperature sensor arrangement allows the accurate measurement of gas velocities much lower than the previously demonstrated limit of 0.3 m/s. The TOF sensor combined with a nozzle creates a new device such that the TOF measured with this device provides a measure of the gas flow rate rather than just the gas velocity. More than one nozzle in series is combined to achieve high flow measuring ranges. Compensation for variations in the thermophysical properties of the gas being metered is provided by pulsing the heated wire and measuring sensor outputs when both are immersed in the gas at zero velocity.
