The minutes of the meeting of the Core Group of RuTAG IIT Delhi held on March 15, 2017 were already circulated to all the members/participants of the Core Group. No comments were received. Hence, the minutes of the last meeting were deemed as confirmed. 

2. Status of On-going Projects

2.1 Adaptation of Sheep-hair Shearing Machine Developed by IIT Delhi. PI: Prof. S. K. Saha 

Prof. Saha informed that most of the components (e.g., flexible shaft, fork, combs, cutters, etc.) were developed except the barrel and its machining which are underway. Field testing of indigenous Motor, Flexible drive, Combs and Cutters was done at Barot, Himachal Pradesh during May 24 – 25, 2017. Total 5 combs and 7 cutters were tested over more than 60 sheep. Things were functioning well. Second test was done at CSWRI, Bikaner on August 25, 2017. Order of 100 sets of comb and cutter was placed with one vendor.

Decision: Committee appreciated the work done by the team.


2.2  Design and Development of efficient and less polluting potters kiln furnace at Bharatpur. P.I: Prof. M. R. Ravi and Prof. Sangeeta Kohli.

Prof. Ravi told that a large number of potters cluster exists in and around Bharatpur, Rajasthan. Existing Kilns are less efficient and more polluting. Three B. Tech students along with Mr. Satendra Rana (an Ex Student of IIT Delhi) and Mr. Davinder Pal Singh visited Bharatpur and Kauruli on February 25, 2017 to collect data related to the existing furnace at Unch village in Bharatpur and carried out energy audit of the existing furnace. CAD model and construction drawing of improved potters kiln furnace were done. Actual construction will start soon by Lupin Foundation.

Decision: Committee noted the said work. 

2.3 Design of an LPG-fired Pottery Kiln for the Pottery Cluster at Uttam Nagar, Delhi. P.I: Prof. M. R. Ravi and Prof. S. Kohli, ME, IIT Delhi

Prof. Ravi informed the members that the pottery cluster at Uttam Nagar uses powdery biomass fuel for their kilns. Sometime ago, the National Green Tribunal has ordered that firing of all these kilns be stopped with immediate effect. A team with Prof. Ravi visited the cluster on February 22, 2017. Two vendors for the fabrication of LPG furnace were shortlisted.

Decision: Committee noted the work. 

2.4 Improvements to the Batasha and Gajak making Stove at Karauli, Bharatpur, Rajasthan. P.I: Prof. M. R. Ravi and Prof. S. Kohli

Prof. Ravi mentioned that the problem came from Society for Sustainable Development, Karauli, Bharatpur. The team who visited the potters kiln in Bharatpur also visited Karauli. The team was disappointed as no Gajak manufacturer and Batasha unit was available.

Decision: Since requirement of furnace improvement was expressed by Batasha manufacturer, Dr. Vinay Gupta will be requested to check if the unit where he is working on Batasha making processes will help in furnace testing or not. It was noted that Gajak requires a different process. Hence, it should be considered as a different project. Mr. Azad and Mr. Hemant will explore possible collab- orators for it.



2.5 Improvement in the Batasha making process. P.I: Dr. Vinay Gupta, HoD, IEC Greater Noida, U. P.

Dr. Vinay Kumar visited several Batasha making units near Noida and Agra. He proposed several CAD models of the processes. Soon one of it will be shortlisted for prototyping.

Mr. S. R. Azad added that his organization will provide handholding for the reduction of drudgery in making Gajak and Batasha. He will find clusters in Madhya Pradesh.

Mr. Hemant expressed his willingness to help in Rajasthan.

Decision: Committee acknowledged the work and accepted the advice of Mr. Azad and Mr. Hemant to study the possibility of identifying Batasha clusters in M. P. and Rajasthan. 

2.6 Proposal for providing contemporary design opportunities and business models for Bharatpur Marble Works. P.I: Dr. Jyoti Kumar, IDDC, IIT Delhi

Mr. Abhishek Dahiya (a student under Dr. Jyoti Kumar) explained that Rajasthan is widely known for its stone sculpting works. However, developing new marble design is still a challenge to the artisans. Therefore, design students visited stone carving units in Baharatpur. Later, Mr. Raj Kumar Gupta and few students created many CAD models for the real prototypes. However, faculty mem- bers who are already working in the said area must be identified and contacted, specially Dr. Gazala Habib must be further updated to find the possibility of taking it as a RuTAG Project.

Decision: Committee suggested Mr. Hemant and Mr. Azad to explore the possibility of stronger handholding in this project, and also try to fetch data related to the emission of marble dust. Mr. Dahiya was asked if the mask design can be looked into by Dr. Jyoti Kumar as well or not.

3. Completed Projects

3.1 Improvement of Furnace for Bangles making and improving the working conditions of artisans. PI: Prof. S. Kohli, Co-PIs: Prof. M. R. Ravi and Prof. S. K. Saha

Prof. Kohli told that two furnaces were installed at Unch village during May 4-8, 2017. One is fitted with refractory material directly, and the other one is fitted over the clay core. Tests were conducted. About 75% of fuel savings was recorded. Unfortunately, one of the groups using clay core furnace stopped using it but the other group continuously used the furnace which is without clay core. After using it for nearly five months, faults in the refractory material started to surface. Mr. Davinder Pal Singh visited site and found discrepancies in the refractory material. He told artisans to stop using the furnace but they continued to use. Eventually the furnace was permanently damaged. Representative of two refractory companies were then called. While efforts are to make this up, Lupin was asked to revive the other furnace which is left idle for a long time. Extension of the project was sought till March 31, 2018 to reconstruct with an additional budget of Rs. 1.5 lakhs.

Mr. Hemant informed that both the groups will start the idle furnace soon, probably by the end of this month.

Decision: The Committee acknowledged the situation and agreed to extend the project till the said date along with additional budget. 

3.2 Design and Development of a Low Cost Ground Water Level Measuring Device. P.I: Prof. A. K. Gosain (Civil Engg. Deptt.).

Prof. Saha told that probe was designed and tested successfully at Chirawa district on July 06, 2016.

Decision: Since the project objectives were met it should be closed. A final report will be sent to the PSA’s office. 

4 New Project Likely to be taken up

4.1 Low cost high productive loom is required as Tara loom is expensive for poor weavers.

Prof. Saha mentioned that the said problem was raised during RuTAG’s regional workshop at Bikaner. Two weaving clusters (Khadi Mandir Industrial Area in Bikaner and Napasar, a nearby village having handloom cluster) were visited by the RuTAG team. Weaver at Napasar told that the cost of the Tara loom should be reduced to make it more affordable. Also, they would like to have some intervention in solar-based loom to make it more user-friendly. At Khadi Mandir a weaver wanted intervention in treadle operating loom. Dr. Arun Kumar was asked to share the complete information of the Tara loom for the exposures to the students, e.g., for optimization, etc.

Major Chatterjee added that both the cluster visited were having different requirements. Hence, a comprehensive view can be taken by probably visiting the sites by Prof. R. Chattopadhyay and Dr. Arun Kumar.

Dr. Arun Kumar added that there is very little scope in further reducing the cost. He is ready to visit the sites. He has no problem in sharing the details of the Tara loom for academic studies.

Decision: Committee agreed for further investigation of the project for better understanding of the problem definition. Prof. R. Chattopadhyay will be requested to take a lead in it. 

4.2 Automatic self-filling syringe with bottle feed attachment which accurately delivers selected dose from 0.25 ml to 10 ml for sheep or any animal vaccination.

Prof. Saha told that this problem was raised by the scientists of ICAR during the regional workshop at Bikaner.

Mr. Davinder Pal Singh added that the same problem was mentioned by the scientists at Hissar Sheep Breeding Farm. Actually, a product with Rs. 25K exist. They wanted to reduce the cost.

Decision: Committee felt that a commercial product is available in the market. Hence, to reduce its cost may not be so easy. CBME of IIT Delhi will be contacted, if any help is available in that direction.

4.3 Safe and reliable method for lifting water from underground storage tanks around Ra- jasthan as it clams many lives every year.

During the workshop in Bikaner, it was mentioned that every year many lives are lost while fetching water from the underground storage reservoirs located outside homes. RuTAG team suggested to install the Treadle pump for taking out water from the storage tank.

Decision: Committee agreed to the solution. 

5 Reporting
