| Patent Application Name and Description |
Status |
| An automated fluid mixer providing output at controlled temperature. An invention is disclosed which maintains nearly constant outlet temperature when fed from two inlet fluid streams at different temperatures. The outlet fluid temperature is sensed by an enclosed mass of air which expands as mixed fluid flows in contact with the heat conductive gas enclosure. Expansion of the gas operates a mechanism to affect the mixture ratio sufficiently to maintain a constant outlet temperature. |
Accepted. Patent to be sealed.

| Enhanced efficiency system for air / fluid circulation An energy efficient system of fluid circulation (for use in large volumes) is described using the example of room air fans (only for better visualization). Conventional air circulation systems in large spaces consist of ceiling fans which all rotate in the same direction, i.e., CCW as looked at from below. Each fan while imparting an axial velocity to air also imparts a small but non negligible component of rotation to the air in the CCW direction. In a region midway between two adjacent fans (“M” in diagram 1), this circulatory component of velocity due to the two adjacent fans is in opposite directions. This results in loss of energy. This wastage is proposed to be eliminated by installing “Inverted Circulators (“I” in diagrams 2, 3) at each alternate location. These special fans are designed to rotate in the CW direction. This makes the circulatory component of flow due to two adjacent fans to be in the same direction in the intermediate region and hence add up. Further the pitch of the blades is reversed in comparison with the conventional fans. Hence the axial velocity imparted remains downwards as for the conventional fans |

| Device For Aiding Peripheral Blood Circulation By Electromechanical Means. A device to aid blood circulation in limbs by affecting venous flow. A true peristaltic pressure wave is simulated by a phased pressurization of a plurality of sets of constrictors encircling the limb. The phase relationship between the constrictors of a set can be optimized, as also the pressure and its peak value. When all the constrictors operate in phase the device can be used to relieve fatigue in a limb, especially legs and feet. By changing the relative phases of the constrictors of a set, the peristaltic motion can be reversed, thus increasing pressure in a limb or extremity, (impeding venous flow). This could be used to enlarge capillaries under proper conditions. |

| Wearable Electrically Heated Footwarmer. A wearable electrically powered foot warmer which may go under or over the regular socks and can operate even when the wearer moves either on foot or in a vehicle. Suitable non-obtrusive cabling provides power from the mains, a car battery, suitable mobile telephone charger, or a suitably located rechargeable battery, which can itself be charged from any of the above sources. |
In process with Patent Office.A floor version was marketed with encouraging results.
