It works on rainfall rate. When the rainfall is more then the wiper actuates very quickly. When the rainfall is slow it means the wiper moves slowly. According to intensity of rainfall the wiper works. it consists of sensors, actuators and cup and wiper mechanism . it has been proved working in Adams simulation and Pro E and Catia modelling. It is very useful in the automation field.

The main difference of these pumps' design compared with the gear pump is the presence of big teeth and big cavities in the gears. The pitch of big teeth and big cavities is greater than the pitch of small teeth in 3, 5, 7 or more times. Besides, the addendum diameter of big teeth is greater than the addendum diameter of small teeth. This simple change in the gear pump design gives the following advantages:

Higher suction lift and ability to deliver high viscous liquids at higher RPM, because high volume of the pocket between two opposite big teeth generates high vacuum at the suction port enabling speed increase when delivering viscous liquids compared with the same liquid pumped ...

Educational CNC machine tools nowadays, it is important to reduce costs This also applies to education and specialized education, courses for CNC machine operators.

Project Objective: Reducing the cost of equipment for CNC training centers, increasing the number of training centers for CNC machine operators, facilitating access to such training, and reducing the cost of such courses will result in a reduction in unemployment. Availability learning to use CNC machines in schools (for youth).

3D technology allows the production of models of existing machines and devices in a reduced scale, while maintaining full functionality. This is an excellent addition to the computer simulation. This year the first construction of such a device was made. It is ...

The Electronic Throttle Control System (ETCS) / Throttle-By-Wire (TBW) / Drive-By-Wire (DBW) all are same species. Nowadays almost all modern automotive engines are outfitted with DBW technology. A DBW system regulates the throttle plate angle by using a servo motor to adjust the inlet airflow rate of an IC engine. It is a complex Throttle Control System as compared to traditional Drive-By-Cable Mechanical Throttle Mechanism. It provides a great freedom to Engine Management System. A State-of-the-Art discrete PID controller is pertained for throttle servo mechanism. The redundancy incorporated in the system for safety reason and the deficiency of Idle Air Control (IAC) valve makes the thing more exigent.

Say Good Bye to Old Mechanical Cable Throttles. It’s fairly possible ...


Industrial pipelines carrying fluids, gas (methane) or liquid (oil), are subject to
rupture from natural or artificial disasters. Consequent contamination, fire
or explosion can be alleviated by prompt valved shutdown of the flowing fluid.
Such shutdowns are now controlled by "central computer" systems. There
is a strict limit of how fast this can safely be accomplished since the abrupt
cutoff of flow can cause shock waves in gas and water-hammer in liquids.
Each exhibits great pressure spikes and could cause further ruptures of
the line. Means and method of ameliorating this is described herein.

First: For prevention of the initial shock, one, preferably more, diversion
valve(s) and for each, ...

Iron filing determination in tea is a need of the hour as FSSAI has introduced the limit at 150 ppm. To date there is no such equipment to measure iron filing in tea. This instrument gives a hassle-free and nondestructive technique to measure the same. The principle and technology:

Neodymium magnetic quadrupole is applied surrounding a tunnel made of non-magnetic material in such a way that the field force becomes maximum in the center of the tunnel. The tunnel is placed vertically so that on loading a sample, the paramagnetic materials present will be retaining in the field where as the rest of the sample will be delivered through the lower end of the tunnel by gravity. On removing ...

Extreme Power Free-Piston Engine
6.0 hp/lb - Highest efficiency - Small & Robust
The pistons of free-piston engines transfer the combustion pressure directly into hydraulic pressure, without a crankshaft mechanism. They are therefore inherently very simple, robust, light and efficient. Their major drawback is the insufficient control of the piston velocity and compression ratio, determined by the combustion and hydraulic forces and the mass of the piston (spring/mass system).

The new compression ignition, 2-stroke, hydraulic free-piston engine consists of a cylinder with two opposing pistons, an exhaust-gas-driven impulse charger, and an ultra-high pressure peripheral fuel injection system. Additional new sub-concepts improve the capabilities of the free-piston engine significantly.

The pistons have a hydraulic section with two opposing ...

One and a half months back one Ms. Juli Boruah (27) came to me. She lost her two hands in a road accident. From that day onwards she has had to depend on others to feed her, to clean her etc. Many times she slept with empty stomach for not getting a helping hand to feed her. With the ornamental hand she is wearing, she cannot perform these tasks. The brave girl wanted me to design a device so that she can have her food independently and also can clean her up. She also did mention it that she has tried her level best with many big institutions already but nothing came out.

The biggest challenge was that it should ...

One of the most challenging factors that hampers our smooth livelihood is the large scale destruction of the river coast, affecting the sociology-economic balance of our economy as well as  creating border disputes among various states and countries. The process of conceptualist and other currently available processes may not protect the river coasts from causing severe consequences for the ecological balance. After all it will be entangled by the rules and regulations of land acquisition and also it is very much expensive.

To overcome these complex problems I’ve come out with a jubilant and overwhelming idea of “Floating Embankment Guard” placed along the river coast without affecting the original soil embankment of the river that will really solve the ...

Using the highly articulated All-Terrain Hex-Limbed Extra-Terrestrial Explorer (ATHLETE) robotic mobility system as a precision positioning tool, a variety of print head technologies can be used to 3D print large-scale in-situ structures on Earth and other planetary surfaces such as the moon or Mars. In effect, in the same way CAD models can be printed in a 3D printer, large-scale structures such as walls, vaults, domes, berms, paving, trench walls, and other in-situ derived elements can be FAXed to the planetary surface and built in advance of the arrival of crews, supplementing equipment and materials brought from prepared sources.

The ATHLETE is a six-limbed wheel-on-limb robotic mobility platform that is capable of transporting large cargo efficiently on both rolling ...
