Inversions of 10 Link 12 Joint 3 F Compound Kinematic Chains
Abstract: Author’s objective is to prepare a catalogue of equivalent and distinct mechanisms in 10 link 12 joint 3 F compound kinematic chains. It will help the new researchers/designers to select the best mechanism kinematic chain and mechanism to perform the desired task at the conceptual stage of design. The suggested technique is based on the visualization of the coefficients of polynomials of the edge-edge matrix. These coefficients have been used …

Preparation of Phase – Pure Nanocrystalline Anatase and Rutile TiO2 using Hydrolysis of TiCl4 in presence of surfactants
Abstract: Hydrolysis of TiCl4 was carried out in two different ways to prepare nano crystalline TiO2. In the first method the hydrolysis of TiCl4 was carried under high acidic conditions at low temperature. In the second method hydrolysis was carried out using (NH4)2SO4 as an additive. It can be seen that the hydrolysis of TiCl4 under high acidic conditions promotes the growth of rutile phase of TiO2, where as hydrolysis in …

QUALITY IMPROVEMENT IN THE FABRICATION OF NUCLEAR VESSEL OF 20MNMONI55 LOW ALLOY STEEL
Abstract: 20MnMoNi55 is very critical material to weld, as the material is grouped into the P3 category according to the ASME Standard, which has lower weldability then other steel. The various parameters affecting the welding of 20MnMoNi55 like Welding current, welding speed, Voltage, Wire feed rate, stick out etc. should be in optimizing range. In this research paper, the attempt has been made to optimize the welding process parameter using Design …

Selection and Mechanism of using active gas in GTAW Process – A review
Abstract: Gas tungsten arc welding process is known for its good quality welds. However, the lack of penetration of the process leads to low productivity. Many techniques have been implemented in the past to improve the joint penetration and thereby the productivity of GTAW process. In one of the technique, active gas like Carbon dioxide, Nitrogen or Oxygen is used in some proportion along with the inert gas. This addition of …
