Title: Measurement of corrosion with curved ultrasonic transducer; rule-based processing of full echo waveforms; preprocessing and transmitting echo waveform information
Inventor: COBB WESLEY N
IPC: E21B47/08
Filed: 1988-11-03
Granted: 1993-03-23
Abstract: ABSTRACT OF THE DISCLOSURE    An acoustic transducer having a curved surface to match the inner or outer surfaces of a target surface such as a cylindrical borehole tubular is disclosed.  A sequence of excitation pulses causes the  transducer  to  launch  a  series  of  high-frequency,  short duration acoustic energy pulses toward the tubular.   The characteristics of the tubular surfaces, including the location, area and depth  of  any  corrosion  pits  on  the  tubular surfaces, are determined from a full echo waveform. A  rule-based  Expert  System  analyzes  the  full waveform  of  the  echo  pulses  returned  from  the tubular to determine the most likely characteris-tics of the surfaces which produced the full echo waveform.   More specifically,  the Expert System uses expertise about the acoustic properties of the target medium, as well as constraints chosen by an expert,  to determine which signal structures are informational  and  which  signal  structures  are confounding,   The present invention also involves preprocessing and transmitting information.   The present invention reduces the absolute amount of information that is transmitted without reducing the amount of meaningful  information  that  is conveyed.   The present  invention transmits more meaningful information  than  conventional transmission systems.   It also reduces the amount of information processing at the destination.            A41.1.WP

Inventor: WESTDORP RUDY
IPC: C21D11/00
Filed: 1988-11-09
Granted: 1993-03-09
Abstract: ABSTRACT OF THE DISCLOSURE        A method for bringing a plurality of steel slabs to rolling temperature uses a furnace having a controllable energy supply.  To accommodate variation of slab temperature at entry, especially mixing of cold and hot slabs, at least one virtual slab corresponding to a group of the steel slabs is determined, and the energy supply is adjusted in dependence on the desired mean temperature at exit from the furnace of the virtual slab.  Suitably the furnace has at least two zones each with an individually controllable energy supply, and virtual slabs are determined for the slabs in each zone.          Then the energy supply in each zone is adjusted in dependence on the desired mean temperature at exit from the furnace of the virtual slab of that zone and preceding zones.

Granted: 1992-11-10
Abstract: ABSTRACT The present invention is a channel changing system in a mobile unit communication system comprising a plurality of radio base stations making communication with movable stations through radio channels and a center station for accommodating such base stations and connecting these base stations with the public telephone network. The center station is configured comprising a private branch exchange for accommodating the public telephone network and the lines extending from a plurality of base stations and a controller for controlling changing of communication channels by supervising the signal receiving condition between a movable station and a plurality of base stations. The controller is configured so that it issues a channel changing command by detecting, based on the signal receiving condition, that a movable station has transferred to the radio zone of an adjacent base station from the radio zone of a certain base station, while the private branch exchange conducts line changing depending on such command through the extension transfer to the line of adjacent base station from the line to the relevant base station.

Abstract: A method of making coreless hollow filament bundles comprises winding a hollow filament 20 around a drum 22 having a number of axially extending vanes 24. The winding is formed in layers, each layer being a helix and adjacent layers being wound in opposite directions axially of the drum so that all the turns of the helix forming one layer cross all the turns of the helices forming the adjacent layers. The winding is then slid along the drum so that it is axially collapsed and forms an annular rope around one end of the drum. The annular rope is then cut into segments, each segment being the length of rope between adjacent vanes 24. Each segment forms a filament bundle and the ends of the filament lengths in each bundle are potted in the usual way.
