Activated Flux for TIG Welding ofStainless Steels transferred toADOR Welding Pvt Ltd., Pune

The present invention would reduce thedistortion of tungsten inert gas welds andproduce welds with mechanical propertiesthat are nondegradable through the use offlux.

Oxygen sensors for On-BoardOxygen Generating SystemThe present invention would do to monitorthe performance of the On-Board OxygenGenerating System (OBOGS) continuouslywith an oxygen sensor.

Potentiometric oxygen sensors usingZirconia electrolyte

An oxygen sensor using yttria stabilizedzirconia solid electrolyte has beendesigned and developed for thispurpose

The response time for a change inoxygen concentration is rapid to alertabout the failure of OBOGS

This technology is being used in light combatair craft (LCA), Tejas. This sensor is requiredfor monitoring oxygen levels in the cockpit ofLCA, when it flies high altitudes. (DEBEL -DRDO Laboratory, Banglore)

High Volume Air SamplerThe present an indigenous invention would be used for collection of air particulates/suspended particle matters in any filter paper medium.

Wireless Remote for safer operation: With the remote device the air sampler can be operated within 20m radius. The remote connects to the embedded controller in the air sampler through Bluetooth connectivity

Timer: The remote has an inbuilt start, stop and pause timer, with which the sampler can be operated for desired time

Flow: It has an inbuilt flow indicator which displays the current flow rate and with the help of embedded controller the data is also shown and logged in the remote unit

Accumulated Flow: It logs the flow for the set time and calculates the accumulated flow automatically using a logarithm which is coded in the remote

GPS / Location: The remote has a GPS which logs approximate coordinates when the sample is taken. This feature would be helpful when the sampling is done in outdoor environments

Flow Controller: It has a flow controller with a precise flow from 40 to 100 CFM [1100 to 2800 lpm] can be achieved precisely

Data Logging: It has a data logging feature which logs date, time, set timer, logging time, flow, location and accumulated flow for the set time
