BIODIGESTER TECHNOLOGY.
Dec 16, 2015

Presented by Dr. Lokendra Singh on 16th December 2015

Biodigester technology has potential to eliminate wide-spread pollution resulting from untreated human excreta and making India cleaner, fulfilling the aspirations of the nation towards 'Swachh Bharat'. The currently publicized making of pit-toilets in rural setting needs to be looked into from the perspective of wide spread ground water pollution that will result from such toilets in near future. The faecal containing watery matter is likely to percolate further down from the pit and may be drawn in the drinking water through nearby hand pumps or bore wells. It is known that consumption of faecal contaminated water invites a plethora of diseases. Thus, by adopting a time tested sustainable and indigenous technology of biodigester, safe "disposal" of human waste is ensured. This will contribute towards a safer and healthy environment of the country. 

Auxetic Textiles: Concept & Applications.
Dec 9, 2015

Presented by Dr. Mahuya Ghosh on 9th December 2015

Auxetic textiles, a category of new generation textiles, are non-conventional materials having Negative Poisson’s Ratio (NPR). Auxetic textiles can be manufactured from auxetic fibres /or auxetic yarns /or adopting normal fabric formation technologies (warp and weft knitting, weaving) employing normal yarns but adopting special constructions. These textile materials have many enhanced properties, e.g., high shear resistance, high indentation resistance, Synclastic curvature, fracture toughness, energy absorption properties, variable permeability, high volume change, etc. Evidently, this group of textiles has diverse and wide spectrum application potential starting from protective textiles, medical textiles up to aerospace applications.

Process and Quality control in jute spinning by using statistical technique.
Dec 2, 2015

Presented by Mr. Debiprasad Gon on 2nd December 2015

Presentation contains various statistical techniques employed to maintain quality of products in a continuous process from Batching to Spinning

Broadly, this involves the application of various techniques and services to optimise the product quality to ensure the connotation of quality as fitness-for-use'. The quality assurance would mean optimisation of quality within given sets of constraints. These constraints, apart from functional limitations, may be related to mechanical capabilities, human skills etc. However, the constraint of cost is almost universally present in this problem of optimisation.

Second part of the presentation includes on assuring quality in yarn production, quality has to be considered with due importance right from the raw material to the finished product i.e. yarn. Basically, each production position can be considered as a potential source of disturbance. The success in preventing the yarn quality downgrading depends not only on the right selection of raw fibre quality but also much on monitoring of each processing stage to ensure an early recognition of faulty running production process and undertaking of the corrective measures to eliminate the faults or to minimise their intensity.

TRANSDUCER & ITS APPLICATION
Nov 18, 2015

Presented by Shri Utpal Bannerjee on 18th November 2015

An awareness program based on the area of major hardware components of any kind of instrumentation project; how the components work; how the energy received by the connected sensors are processed in analogue or digital processing system; what major criteria are to be considered; how electronic sub systems work as input & output device; which transducer or sensor should be chosen for optimum performance and so on.  

In order for an electronic circuit or system to perform any useful task or function it needs to be able to communicate with the real world through some device.Since a transducer or sensor receives its input signal from a source of invisible energy like electrical or magnetic field; heat; sound; light etc. it should be able to communicate with the real world through a device called instrument or equipment. 

 

ENERGY MANAGEMENT IN JUTE MILLS
Nov 11, 2015

Presented by Mr. Debabrata Samanta on 11th November 2015

The study was carried out in four jute mills on the consumption of electrical energy in 4.25” SD (two legged flyer) spinning frames. It has been observed that in place of existing 15HP motor, the spinning frames can be safely run with super efficient 12.5 HP motor which can save 8-10% electrical energy. Schedule of preventive maintenance and overhauling is required to be followed for the long term benefit.

ENZYMATIC RETTING OF JUTE RIBBONS
Oct 30, 2015

Presented by Mr. Samar De on 30th October 2015.

The feasibility study of enzymatic retting of jute ribbons has been presented. It has been observed that appropriate enzymes can ret jute ribbons within 8-10 days depending on doses of enzyme application & retting ambience.

Introduction of An Autolevelling System in Jute Carding Machine
Oct 14, 2015

Presented by Mr. Suvankar Bej on 14th October 2015.

Carding of Bast Fibres (like Jute) is the most complicated stages of fibre processing. The extent of irregularity in Finisher Drawing Sliver are mainly depends on the Carding process.The Concept of new advance Autolevelling technique has illustrated in this presentation.

Studies on isolation and estimation of Lignin in Jute
Oct 7, 2015

Presented by Mr. Rajkumar Paral on 7th October 2015.

The morphology of jute and importance of lignin in the structure was discussed. A critical review on the isolation techniques and its drawbacks were related to the developed method of rapid lignin estimation from jute. The method of dewaxing jute and standardization of lignin estimation was reviewed.
