Insight 150 OMR



When you need to collect vast amounts of data quickly and accurately, turn to the iNSIGHT 150 scanner–a high performance scanner with speeds up to 250 pages per minute. The iNSIGHT 150 interprets optical mark read (OMR), hand- and machine-printed characters, bar code, and mark sense. With the iNSIGHT 150, you get the best performance for the price from a trusted source–we've been manufacturing industry-leading scanning systems for more than 50 years.


Save Processing Time:

Capture images and OMR data in a single pass through the scanner. You can gather multiple choice, objective test, or survey responses at the same time you capture images of short answers to constructed response items on tests or comments on survey forms.


Tie Images to Data Records:

Images can be tied to an OMR data record, archived, and retrieved later for review or evaluation. Route essays, survey comments, and other images to reviewers for final evaluations.


Design Forms for Efficiency:

Because the scanner reads both handprint and machine printed characters, you can design data collection forms to be more aesthetically pleasing and make better use of space. End users will also thank you for not requiring them to fill in large bubble grids for name, address, ID numbers, and the like.


Pre-print Encoded Data:

Lessen the amount of data you require from form users by pre-printing encoded data. You can also verify and cross-reference data to external databases by reading pre-printed bar codes, mark sense, and binary coded numbers.

Meet Accuracy Standards:

The following technologies help you meet accuracy standards with the least amount of effort on your part.

* Picture Perfect™ - ensures that hand- and machine-print characters are quickly
and accurately interpreted by minimizing the effects of mechanical distortions.
* Image Quality Sentry™ - minimizes the accumulation of inferior quality images.

These features operate as each sheet is scanned. They are transparent to the user and are designed to improve the accuracy of data without slowing the scanning process. Further, these features minimize the amount of post-processing required; thereby, optimizing the total production.


Fast and Productive:

Our mid- and high-volume iNSIGHT scanners perform many tasks at the scanner, and as a result, improve efficiency and minimize costly errors:

* Dynamic Deskew™ and Image Skew Sentinel features reduce the occurrence of 
sheet skew errors
* Gray-box Search processes only fields that contain data. Or, it can isolate
forms that are missing critical fields, like a signature.
* Optical character recognition (OCR) increases data productivity by reading 
pre-printed characters while scanning in real time. This avoids the need for
pre-slugging data.

Image Formats Meet Industry Standard:

Included with every iNSIGHT system is ScanTools® Plus scanning software for developing forms scanning applications. In addition, the system outputs industry-standard image formats which are fully compatible with most archival/retrieval systems.

ScanTools Plus software verifies booklet identification and sheet sequence as each sheet passes through the scanner–another fail-safe to help ensure that the highest quality data is captured.


Data Collection Methods:

With an iNSIGHT scanner, you choose the methods of data collection that best meet your needs:

* Mark sense (bubbles, checks, tick marks)
* Bar code
* Gray-box search (there/not there)
* Key from image (for open-ended questions or comments)
* Gray-scale image capture for viewing drawings, photographs, and signatures
* Dropout colors to enable both pencil and ink read capabilities
* Handprint and machine print characters interpreted and converted to ASCII data.
* 16-level OMR mark discrimination evaluates the relative darkness of a mark in order to discriminate between smudges and erasures and valid marks.

Knowledge About Textile Machine

YJN DYEING MACHINE



General information:

This new overflow dyeing machine used roller and fabric lifting system. The roller running at variable speeds and the fabric passing through the jet nozzles coordinate rationally. By regulating the nozzle gap, the pump's speed and fabric lifting's speed, it's possible to dye various fabrics with different requirements. Also avoid fabric jam in front of the nozzles and guarantee the great quality of fabric's surface.Front and rear medium-pressure twins jet nozzles system. The front nozzle sprays on the fabric rationally and the rear nozzle sprays on the fabric again and conduct it. The two nozzles in one tube are connected in series and therefore the pressure and flow rate of water for every group of nozzles are distributed evenly with a result of shortening the dyeing batch time remarkable, making the color distribution better and achieving the best dyeing effect.The fabric swing device works at a swing amplitude of 80° and put the fabric in the rear chamber. It avoids the fabric pile from collapsing when at a maximum capacity loading and make sure a better operation of dyeing.For the front nozzle, adjustable pressure rings are added to alter the wrapping angle between fabric and lifting roller so as to reduce the slippage between fabric and roller, enhance the fabric’s lifting force and avoid fray out of friction.The inside rotational cleaning device can be detached and make the clean job better and quicker.Specialized dyeing and finishing pump, professional B model for chemical engineering, is adopted. The body is made with high anti-corrosive stainless steel. The flow rate is regulated with frequency inverter to ensure a better dyeing result. The pump slow-starts with frequency inverter ensure a normal running in a reduplicate way.With a vertical appearance in general, the internal structure is a detachable cylinder to achieve an even circulation of staining solution inside the cylinder and to strengthen the dyeing effect.The tubular grid mesh (Teflon conduit, concave hole separate plate) in the inner layer of lower cylinder body thoroughly improves the dyeing environment of fabric in the cylinder, separates the staining solution from fabric effectively, promotes the regurgitation of staining solution and consequently achieves a lower liquor.

Water Tube Boiler











he industrial water tube boiler typically produces steam or hot water primarily for industrial process applications and is used less frequently for heating applications. In the water tube design, tubes contain steam and/or water and the products of combustion pass around the tubes. Typically, water tube designs consist of multiple drums. A steam drum (upper) and mud drums (lower) are connected by the tubes, which form both the convection section and the furnace area. Packaged industrial water tube boilers are typically rated in pounds of steam per hour output at operating conditions and range from 10,000 to 150,000 lbs/hr. Industrial water tube boilers are noted for their fast steaming capability and high steam quality. Steam is generated very rapidly because of the relatively low water content, thus allowing quick response to changing load demands.

The industrial water tube boiler design makes it capable of generating either saturated or superheated steam. When applications dictate superheated steam, large or fluctuating steam loads, high pressures or high steam quality, an industrial water tube boiler should be considered.....
