  • Patent number: 4742667
    Abstract: An apparatus for packaging a product in containers includes a sterilization station and a conveyor for intermittently conveying containers to the sterilization station. A vaporizing nozzle communicates with a reservoir of liquid disinfectant containing hydrogen peroxide and a source of compressed air. The nozzle is intermittently opened and closed whereby the compressed air vaporizes the disinfectant and a mixture of liquid disinfectant in fine droplets and compressed air is ejected when the nozzle is open. A tube is connected with its intake end at the nozzle and is disposed parallel to the jet emitted from the nozzle. A heater on the tube heats the inner surface of the tube to a temperature that is sufficient high to rapidly evaporate the disinfectant in the mixture. As a result a mixed flow of compressed air and evaporated disinfectant leaves the output end of the tube and enters the container in the sterilization station.

  • Patent number: 4735777
    Abstract: An apparatus for measuring metabolites contained in human expired air and for measuring metabolites contained in human urine and for extracting a correlation between the metabolite data in the expired air and the metabolite data in the urine is suitable for parallel analysis of the metabolites in human urine and expired air. An atmospheric pressure ionization mass spectrometer is suitable for measuring metabolites in the expired air. By storing reference data showing the relation between the metabolites in the expired air and those in the urine and, by comparing such data with a subject's metabolite data in the expired air and the metabolite data in the urine, abnormality of a subject can be detected.

  • Patent number: 4729875
    Abstract: A device for performing a plurality of immunochemical assays simultaneously comprises a waste reservoir about which are positioned at least two assay tubes connected in series by conduits formed in the base and top of the reservoir structure. A compound syringe is insertable into an opening formed through the top of the waste reservoir, the syringe being held in place by a receiving structure formed in the base of the reservoir and connected to the entrance end of the series of assay tubes. The various compartments of the compound syringe are emptied in sequence to cause the flow of sample and assay reagents to flow through the assay tubes. The device is structured to allow for the reflow of sample through the tubes if desired.

  • Patent number: 4697465
    Abstract: A corrosion coupon holder for inserting and removing a coupon from the interior of a pipeline while under pressure has an elongated housing with a threaded connection at one end and a removable closure device at the other end, the housing connection to be attached to a pipe entry valve which is connected as a branch to the pipeline. The housing other end also carries a guide body having a bore which guidingly and sealingly receives a rod for inserting a coupon having a safety stop element at one end to hold the coupon, the guide body having a split collet associated with the bore with a locking screw mounted to act on the collet to fixedly clamp the rod in the bore of the guide body and the housing having a bleeder valve communicating with the interior to relieve pressure from within such interior.

  • Patent number: 4692415
    Abstract: The present invention provides a process for the determination of cyanamide in plants or plant parts, wherein(a) the cyanamide is extracted from the plants,(b) it is subsequently reacted in aqueous alkaline medium with 1,2-naphthoquinone-4-sulphonate to give 4-cyanimido-1,2-naphthoquinone,(c) this reaction product is separated by high performance liquid chromatography on a reverse phase and(d) it is determined spectrophotometrically at a wavelength of 485 nm or 272 nm.

  • Patent number: 4687637
    Abstract: Apparatus for effecting multiple treatment steps needed to regenerate spent hydrocarbon conversion catalyst. Catalyst is contacted with a hot oxygen-containing gas stream in order to remove coke which accumulates on the catalyst while it is in a hydrocarbon conversion zone. After the coke is burned off in a combustion zone, catalyst is passed into a halogenation zone wherein a halogen is deposited on the catalyst. Catalyst leaving the halogenation zone is passed into a drying zone for removal of water formed in the combustion zone which has remained on the catalyst instead of being carried off with combustion gases. Water removal is accomplished by passing a hot dry air stream through the catalyst in the drying zone.

  • Patent number: 4687643
    Abstract: Apparatus for preparing spherical, submicronic, monodispersed, and non-agglomerated particles of metal oxides by reacing with steam a gaseous stream containing an aerosol of liquid particles of a hydrolyzable metal compound. The apparatus is characterized in that into a duct, in which an inert gas stream containing vapors of a hydrolyzable metal compound flows, there is fed through a nozzle a cold inert gas stream, the temperatures and flows of the two gaseous streams being such as to establish in the duct a temperature lower than the condensation temperature of the metal compound; the mixed gaseous streams having a turbulent flow in the duct, with a Reynolds number equal to or higher than 1800. At the duct outlet, the aerosol of metal compound liquid particles, which has formed in the duct, is caused to react with steam, wherefore solid particles of hydrated metal oxide form, which are subsequently calcined to the oxide.
