A Liquid dielectric Transducer
Disclosed herein is a simple low-cost device to measure direct dielectric constant of a given liquid. It converts dielectric constant of liquid into its equivalent capacitance. The device uses carbon/graphite sheet as electrode and electrically insulated material is used as an enclosure. The device maintains constant volume of liquid in it and hence measures exact dielectric constant of the liquid. This device can be used to measure directly the dielectric constant of any liquid of type acidic, basic, corrosive, polymer, toxic etc. The device finds application in measuring quality of water, milk, petrol, diesel etc. It finds application as a sensor in measuring direct dielectric constant of any liquid used in petrochemicals, fertilizers, chemical, textiles, leather and polymer industries etc. Indian Patent application no. is 201611033415.
Detachable Mrudangam
The present invention provides a modified Mrudangam, a south Indian percussion instrument. The modified instrument is travel friendly, whereby the right and left playing drumheads along with the adjacent region of the shell are separated and accommodated into the hollow of the remaining portion of the shell which when attached again restores the shape, dimensions and functionality of the musical instrument. The overall size of the Mrudangam unit has been reduced as it is split down to smaller units that are housed within themselves so that they can be carried / transported conveniently. This has potential application in the field of percussion instrument manufacture by making it not only convenient for travel but also environment friendly by reducing the stress on the trees whose wood is used for making the shell as it requires only small pieces of wood while the conventional design requires lengthy and defect free logs. The invention has been applied for patent protection (Indian Patent application no. 804Del2013).
Clean Self-Draining Water Conservative System for Urinals
Disclosure essentially relates to flow control of water to the urinal. It relates especially to valve control of water released to the urinal or toilet. Standing point of urinal (SPU) on which a person stands to urinate is designed as a module and it controls flow of water as and when a person stands on it. The SPU is solid platform and middle of it is attached to a fulcrum. It operates valve to control the flow of water. Limited amount of water is drained into urinals before use to refresh, during the use to dilute and after use to clean and remain fresh without use of electric, electronic or sensory devices. The unique feature of the system is that it is a simple mechanism free from any maintenance requirement. The invention has been applied for patent protection (Indian Patent application no. 3481Del2012).
Rescue system for parachuting of the aircraft broken during the flight
Disclosed herein is a rescue system for parachuting of aircraft broken during flight, which comprises two parachute cabins and dedicated parachute path for each. Parachutes are located in the roof of the cargo cabin and fixed with the middle frame of the aircraft fuselage. The front-end dedicated parachute path lets the parachute cabin to move vertically down and to lift the frontal part of the aircraft piece. The rear-end dedicated parachute path lets the parachute cabin to move horizontally and to lift the remaining part of the aircraft. Parachute cabin has a strong cap to clear the hurdles on the path, a drogue parachute, a main parachute and thrust rockets to eject the cabin out of the aircraft. A string and string roller enable the main parachute to have free movement and firm connection with the middle frame of the aircraft. As the aircraft is parachuted vertically upright, passengers are seated and communication with the control system can be established. Indian Patent application no. is 2358DEL2014.
