Filed: 1979-10-01
Abstract: A gas analyzer and gas analyzing method are described of the non-dispersive infrared type wherein infrared energy is passed through a sample cell containing an unknown mixture of gas. The infrared energy passing through the cell is received by a detector and an electrical signal is produced representative thereof. A rotary filter wheel positions at least one filter in the path of the infrared energy, resulting in a pulsating detector output. The electrical signal is processed to produce an output indicating the concentration of the constituents of the gas mixture in the sample cell. Synchronization with the processed electrical signal is obtained by deriving synchronizing pulses directly from the electrical signal produced by the detector.

Abstract: A feed gas is passed to a pressure swing adsorption system, each bed of which undergoes a processing cycle that includes (1) pressurization (2) copurge at upper adsorption pressure, (3) countercurrent depressurization, including, in some embodiments, evacuation to a lower subatmospheric desorption pressure. By recycling effluent gas released upon copurge and countercurrent depressurization for use in the pressurization or the copurge step, the more readily adsorbable component of the feed gas is advantageously recovered at high purity and at high recovery levels. Enriched less readily adsorbable component is also recoverable as coproduct effluent at relatively high recovery levels. The process can be advantageously employed for the separation and recovery of product nitrogen from air.

Abstract: Apparatus and accompanying methods for inclusion in a Coriolis meter that substantially eliminate temperature induced measurement errors which might otherwise be produced by performance differences existing between the separate input channels contained in the meter. Specifically, two pairs of input channels are used in the meter. In operation, the meter repetitively measures the internal phase delay of each of these pairs and then subtracts the delay associated with each pair from actual flow based measurement data subsequently obtained therefrom. While one channel pair is measuring actual flow, the other channel pair is measuring its internal phase delay, with the channels being continuously cycled between these functions. Because both channel pairs are cycled at a sufficiently rapid rate, the current value of the internal phase delay for each of the pairs accurately reflects any temperature induced changes then occurring in the performance of that pair thereby eliminating substantially all temperature induced error components from the flow measurements subsequently obtained therefrom. In addition, the meter measures flow tube temperature in a manner that removes temperature induced errors therefrom.

Abstract: A method is provided for multiplying the number of copies of a target polynucleotide sequence comprising a series of primer hybridization, extending, and denaturing steps to provide an intermediate double-stranded DNA molecule containing a promoter sequence (through the use of a promoter-sequence-containing primer) incorporated upstream from the target sequence. The double-stranded DNA intermediate is then used to grow multiple RNA copies of the target sequence. The resulting RNA copies can be used as target sequences to produce further copies. Multiple cycles of this sort can thereby exponentially increase the number of target sequence copies.

However, existing methods are either inherently unsafe because they bring concentrated hydrogen peroxide into contact with a concentrate of transition metal decomposition agents for peroxide and a purification resin which acts as a source of carbon, or are unable to attain the desired impurity level. In the instant purification process, the hydrogen peroxide solution is passed through a membrane having a very small pore size which contains an ion exchange resin that is capable of removing alkali and alkaline earth metal ions from solution. The feed solution in characterized in that it contains no more than a small proportion by weight of transition metals that catalyse hydrogen peroxide decomposition compared with the total metals content. The feed solution in some embodiments results from a prior treatment of an iron or copper contaminated solution with a dispersion of stannic oxide.

Abstract: A limited backflow reflux valve for connection between a syringe, catheter, and bulk container of injection fluid. The reflux valve permits injection of fluid from the syringe through the catheter into the patient, and also permits refilling of the syringe from the bulk container, without disconnection of any tubing. The reflux valve also permits a limited volume of fluid to backflow from the catheter into the syringe, so that the catheter may be checked for patency, but prevents any further backflow along this path after this limited volume. Therefore, the limited backflow reflux valve not only permits injection through the catheter, but also permits both withdrawal of blood from the patient and refilling of the syringe from the bulk contrast media container, without requiring disconnection of the catheter or other tubing and without risk of contamination of the syringe or introduction of air, increasing the efficiency of the injection process, enhancing safety, and reducing waste of injection fluid.
