  • Patent number: 7678236
    Abstract: Disclosed is a system and method of data transmission/reception in which picture signals are encoded into image data, the attribute information of the image data is obtained, meta data are generated from the attribute information of the image data. The image data and the meta data are transmitted separately. With this system and method of data transmission/reception, when predetermined conditions are satisfied, i.e. only when a moving body is detected or abnormal data or data including significant information are detected, image data and meta data are transmitted. Therefore, since not all the data are transmitted, the amount of transmitted data is reduced. As a result, the amount of data accumulated in data recipient can be reduced and the load of data analysis operation can be alleviated. In addition, the burden on an operator visually monitoring image data can be eased. Furthermore, inadvertent failure in checking abnormal data or data including significant information can be prevented.

  • Patent number: 6660130
    Abstract: Prior to carrying out a gaseous phase chemical reaction, a liquid phase organic compound which is prone to degrade is vaporized at elevated pressures with the aid of a second compound which together with the organic compound produces a mixture having a boiling point less than that of the organic compound. In one embodiment of the invention, vaporization is effected by co-vaporizing a mixture of the two compounds in a vaporiser. In another embodiment, the first compound is injected into a hot gaseous stream and undergoes atomization into droplets which then vaporize within the gaseous stream. The second compound is used to assist the atomization process and/or to sweep atomized droplets of the first compound away from hot surfaces where the first compound would otherwise tend to undergo degradation if the droplets are allowed to reside in contact with such surfaces.

  • Patent number: 4808270
    Abstract: For the preparation of an ether, e.g., tertiary amyl methyl ether, an olefin-containing feed stream is catalytically etherified with an alcohol, e.g., methyl alcohol. The etherification product is fractionally distilled into an overhead fraction containing essentially unreacted, light hydrocarbons and unreacted alcohol and into a bottoms fraction containing essentially the desired ether. The overhead fraction is condensed and cooled to resultant immiscible phases, of which one contains essentially the alcohol and the other contains essentially the hydrocarbons, are removed separately from each other. Water may be added to the overhead stream to facilitate the formation of the two liquid phases.

  • Patent number: 4581133
    Abstract: An apparatus (10) for use with a dry cleaning system having a filter for filtering the dirty solvent comprises a first pressure vessel (28) for vaporizing the filtered solvent and a second pressure vessel (58) for condensing the vapors into purified liquid solvent for collection and reuse. The upper end of the second pressure vessel (58) is upset to provide an annular chamber about the upper end of the condenser coil (76) which extends in closely spaced apart relationship into the reduced lower end of the second pressure vessel, so that clogging is avoided and better contact with the condenser coil and thus more complete condensation is achieved. In the preferred embodiment, the apparatus 10 includes a valve arrangement (104, 106, 108 and 118) by which the filter can be backflushed with hot fluid, such as steam in order to recover solvent from the saturated filter and render it safe for ordinary disposal.
