Title: Processes for refining butylacrylate
Inventor: HO FUNGAU
IPC: C07C67/54
Filed: 1997-05-27
Abstract: Crude butyl acrylate streams, e.g., from the reaction of butanol and acrylic acid, are refined using a splitter distillation column to yield a butyl acrylate- and heavies-containing bottoms fraction and an overhead fraction containing dibutyl ether, butyl acetate, butanol and butyl acrylate. The bottoms fraction is then subjected to separation, e.g., by distillation, to separate heavies from the bottoms fractions and to recover butyl acrylate. A  process for the production of butyl acrylate is also disclosed, which process comprises not only the above-mentioned refining steps but also includes the steps of withdrawing from the splitter distillation column the overhead fraction and distilling the overhead fraction to recover a bottoms stream containing butanol and butyl acrylate, at least a portion of which could be recycled for reaction with acrylic acid to make butyl acrylate, and recovering the separated heavies, at least a portion of which could be recycled to a reaction zone for the production of butyl acrylate. At least 10,000 lb(avoir) quantities of a butyl acrylate product comprising at least 99.8 wt.% butyl acrylate and containing not more than about 200 ppm butyl ether and not more than about 200 ppm butyl acetate are producible.

Title: Combined internet and data access system
Inventor: JESKE CHARLES E
IPC: H04L29/08
Filed: 1998-09-23
Abstract: The inventive system and method distributes information between databases (DB) and web servers (102), via a plurality of interconnected platforms (105) or nodes. A session manager,that is resident on only one platform, manages information flow between the databases and the web servers. The session manager uses a manager thread to determine which platform will operate on the request. At least one data gateway (106) resides on each platform. A  processing thread of the data gateway invokes an application module to create an application, which retrieves the requested information from the database.  The processing thread translates the request into a format useable by the application. The processing thread retrieves a dynamic HTML template file and uses the information retrieved from the database to populate the HTML template file to form the response to the request, and passes the request onto the global network server.

Title: Fibre grating stabilized diode laser
Inventor: ROGERS GRANT
IPC: H01S5/40
Filed: 1995-06-28
Abstract: A fibre Bragg grating (34) is used to stabilize the intensity and frequency fluctuations of a diode laser (26). The diode laser is connected with an opto-mechanical apparatus to the fibre which contains the grating. The grating is formed in the guided-mode region of the optical fibre (32). The wavelength of maximum grating reflectivity is selected to lie near the maximum of the diode laser gain bandwidth. The output facet of the diode laser has a reflectivity approximately equal to or greater than that of the fibre Bragg grating. The magnitude. and bandwidth of the grating reflectivity stabilizes the diode laser output without appreciably reducing the optical output power from the end of the fibre. The bandwidth of the optical spectrum of the diode laser is selected depending on the distance of the grating from the diode laser.

Title: Data calls using both constant bit rate and variable bit rate connections
Inventor: BOLDT DEAN
IPC: H04Q11/04
Filed: 2001-01-18
Abstract: A first call processing system advantageously uses a constant bit rate connection and a variable bit rate connection to utilize the bandwidth for a data call.  The first call processing system receives signaling for the data call. The first call processing system then processes the signaling to generate a first instruction to set up a constant bit rate connection for the data call between the first call processing system and a second call processing system. The first call processing system processes the signaling to generate a second instruction to set up a variable bit rate connection between the first call processing system and the second call processing system. Any bandwidth that the data call does not need and use can be utilized for other calls. Thus, the performance of other calls is improved.

IPC: B07C5/342
Filed: 1999-03-29
Abstract: A method of recognising and detecting colours is disclosed, to allow recognition and sorting of objects. Pixels of a colour image of an object to be recognised are received, the hue, intensity and/or saturation of each pixel is determined, the hue, intensity and/or saturation of each received pixel is allocated to a plurality of predetermined hue, intensity and/or saturation bands respectively to obtain hue, intensity and/or saturation distribution values respectively for the colour image, and the distribution values for the colour image are compared with the distribution values from one or more reference objects to determine if the object is recognised as a said reference object. This method of object recognition is independent of the image complexity and the number of colours on the object to be recognised. The method operates to compare a hue signature of the object to be recognised with a hue signature of a reference object.
