Abstract: Hydrogen gas is generated on demand by reacting hydrochloric acid (haloacid) and a pure metal by flowing the acid upwardly through a bed of metal particles held on a distributor plate within a sliding tray. The tray reciprocates in a retaining vessel. A port in the retaining vessel can be aligned with a drain port in the sliding tray (below the distributor plate) so that the solution in the bed can be shunted directly to an annulus between the retaining vessel and the reactor jacket, thereby eliminating contact of acid and metal and stopping the generation of hydrogen. A coolant may be circulated in the base of the retaining vessel to control the temperature of the acid as it enters the bed, thereby helping to control the reaction rate.

Abstract: An improved process and apparatus for making carbonated beverages in which water is mixed with a syrup and the resulting mixture is carbonated and filled into containers in a filling line, the improvement is the following:a sample of beverage is continuously removed before the beverage is filled into containers and then the sample is passed into a cell of a photometric analyzer and the concentration of syrup is photometrically measured which generates a signal; the signal is fed to a process controller which compares the signal to a signal stored in the controller having been generated by the photometric analyzer of an analysis of a sample of a standard beverage containing a predetermined level of syrup concentration and precisely determines the deviation of syrup concentration of the sample from the standard; a trim amount of water is added to the beverage to control the syrup concentration of the beverage to the concentration level of the standard; and the beverage is passed through a static-in-line mixer t

Abstract: An exhaust gas purifying apparatus employing a 3-way catalyst has either a Y-type zeolite or a mordenite as an adsorbent for adsorbing a harmful component in exhaust gas which is disposed at the upstream side of the catalytic converter so that, when the exhaust gas temeprature is not higher than a specific temperature, a harmful component is adsorbed by means of the adsorbent, whereas, when the exhaust gas temperature exceeds the specific temperature, the harmful component desorbed from the adsorbent is introduced into the catalytic converter. Further, an activated carbon trapper and a by-pass are provided in parallel at the upstream side of the adsorbent so that the flow paths of exhaust gas are selectively switched from one to the other in accordance with the level of the exhaust gas temperature.

A rigid receptacle is in fluid communication with the other of the portions of the cavity.

Abstract: A process and an apparatus for performing analyses in liquid chromatography, by means of a pump capable of drawing a fluid and injecting it at high pressure, through at least a control valve, into a separation column. To obtain maximum precision as required by the analysis, before each analysis or each group of analyses, or with respect to each fluid used, a pump stroke is performed with the pump delivery side shut off in order to record and memorize the characteristics of compressibility of the fluid. These characteristics are kept into consideration in the subsequent operative stages to obtain an exactly constant delivery of the feed pump to the separation column.

The unit includes apparatus for selectively extracting, handling, heating, and reinserting a tube from the magazine. The tubes are heated to drive off the contents and flushed to clean the inside of the tubes.

Abstract: A system for detecting trace concentrations of an analyte in air and includes a preconcentrator for the analyte and an analyte detector. The preconcentrator includes an elongated tubular container in which is disposed a wettable material extending substantially the entire length of the container. One end of the wettable material is continuously wetted with an analyte-sorbing liquid, which flows to the other end of the container. Sample air is flowed through the container in contact with the wetted material for trapping and preconcentrating the traces of analyte in the sorbing liquid, which is then collected at the other end of the container and discharged to the detector. The wetted material may be a wick comprising a bundle of fibers, one end of which is immersed in a reservoir of the analyte-sorbing liquid, or may be a liner disposed on the inner surface of the container, with the sorbing liquid being centrifugally dispersed onto the liner at one end thereof.

Abstract: A thin, convoluted wall member disposed upstream of the inlet of a diffuser generates large-scale vortices having axes in the downstream direction. The vortices enhance mixing within the diffuser and can also energize the boundary layer, thereby improving diffuser performance and delaying the onset of stall. Greater diffusion angles without stall are possible. The member itself creates low losses.
