1. Title of Invention: Modified Low Cost Solar Water Purifier

Modified Low Cost Solar Water Purifier

Inventor Name: - DANISH AHMED, Associate Professor

Status: - PATENT GRANTED 

Patent Number: 359965

Brief Introduction: -

The water purifier is more useful in remote areas where there are no sources of fresh water supplies. It consists of a sedimentation tank, solar evaporator, collection system and thin film evaporation trays. With this equipment, we can purify even very muddy water to get 100 % pure water containing no suspended or dissolved impurities using solar energy. It consumes no power and hence is eco friendly. The unit is presently being used in NIT campus to produce distilled water for laboratory use. Thorough experimentation has been carried out regarding quality and quantity of water treated by this unit.

 2. Title of Invention: Low Cost Gas Vent for LPG Heaters

 Low Cost Gas Vent for LPG Heaters

Inventor Name: - DANISH AHMED, Associate Professor

Status: - Published in the Patent Office Journal Issue 12/2020 pp. 45, Dated 20-03-2020

Application Number: 202011010017

Date of Filing: - 03-03-20 

Brief Introduction: -

We often experience indoor air pollution while using an LPG heater. We can sense some form of smell and head aces after using the LPG heater. Vented heaters are available, but are very costly and their gas consumption is very high. The idea is to provide a vent to our already existing heaters. But it would result in a huge heat loss. So, expulsion of harmful gases, yet retaining the heat was a challenge. The gas vent designed has heat absorbers inside whereas heat radiating fins are provided from outside. With this arrangement, the heat is trapped inside the room whereas harmful gases are expelled out. Thorough experimentation using various gas meters and temperature meters has been done. The thermal efficiency noted varies from 85% to 90 %. The vent is very easy to install and can be done by the consumer once mass production starts. The life span of the product 15 to 20 years if used properly and the initial cost is affordable even by a lower middle-class family.

3. Title of Invention: Portable  Low  Cost  Instant  Water  Filter

Inventor Name: - DANISH AHMED, Associate Professor

Status: - Published in the Patent Office Journal Issue 38/2020, Dated 18-09-2020

Application Number: 202011034204

Date of Publishing: - 18/09/20 

Date of Filing: - 10-08-20 

Brief Introduction: -

The portable Low Cost Instant Water filter has been designed to be carried while travelling. It can be carried in the back pack and used any time. It has to be filled with any raw source of water and high pressure filtration process will give us a glass of pure water under one minute where as normal gravity filter would take around  sixty minutes plus  to deliver the same quantity of water. It filters 99.90 % of suspended impurities including bacteria. Two variants have been designed and fabricated. One is the Solo variant of  300 ML capacity and other is the Family Variant of around 800 ML capacity. Food Grade materials have been used for fabrication.

4. Title of Invention: Four Digit Very Low Cost Electronic Combination Lock 

Inventor Name: - DANISH AHMED, Associate Professor

Status: - Published in the Patent Office Journal Issue 42/2020, Dated 16-10-2020

Application Number: 202011039589

Date of Publishing: - 16/10/20 

Brief Introduction: -

The low cost combination electronic lock can be installed on cupboards, drawers, storage boxes . In the figure, it is installed in a demo plastic box. The lock can be opened by only the person who knows the number combination. The combination switches are located on top left corner(4 Nos). They are actually fan regulators connected in series. Putting the right combination completes the circuit to open the lock. A small DC motor and gear system is also put in place. The normal combination lock costs rupees five thousand plus. This one can be made for under rupees five hundred. If the combination numbers are exposed, they can be easily changed within minutes by the user.

5. Title of Invention: Low Cost Atmospheric Water Extractor 

Inventor Name: - DANISH AHMED, Associate Professor

Status: - Published in the Patent Office Journal Issue 44/2020, Dated 30-10-2020

Application Number: 202011043979

Date of Publishing: - 30/10/20 

Brief Introduction: -

In certain places, there is not a single drop of water to sustain life. The humidity of the atmosphere can be trapped by this invention, which uses simple materials and concepts, The yield can be around 150 ml per M2 of the setup area at 80% relative humidity. It yields water due to solar energy. No maintenance, no operation procedure, simply automatic. You have only to go and fetch water from it. I have used a combination of four local absorbent , cheap, throw away materials. No high costs involved. A working prototype has been used and tested to arrive at the expected yield. The output water is free from all impurities and is potable.
