The problem we are attempting to address through our product, Chroma, is the skilled labor demand in the paint industry in India. By 2020 will have 50 percent of its population in working age group, making it the skill capital of the world. However skilling this population is a challenge considering that 90 percent of them are in the unorganized sector. The remaining population who has received the formal vocational training has picked up the skill through on job training than during their formal training years.

In order to rapidly skill this huge population effectively, Chroma range of simulators are offered to paint training institutes to meet their skilled labor need.

The heart of the product is the 'psychophysics' ...

This machine is designed in such a way that all the three processes:

Roasting of groundnut, Separation of groundnut shells from the groundnut seed, and the oil extraction is done in a single unit without any human interference.

The machine components are:

bowl feeder, crushing rollers, conveyor tray, vibrating tray, hopper and extracting chamber.

The fabricated machine is then tested to establish the influence of moisture content, heating time and temperature on percentage oil yield. The machine has an extraction capacity of 85 kg/hr with the screw shaft rotating at 53 revolutions per minute and a reduction gear to step down the speed of rotation to ratio of 27:1. The roaster was equipped with; a barrel heater. The machine ...

A fixture is a device used for holding the workpiece during the machining operation, more versatile to work as specialized machine tool even with the advancement of manufacturing industries. There is a continued use of fixture either in same form or other, either independently or combination with other system in machining fixture, minimizing work piece deformation due to clamping and cutting file is essential to maintain the machining accuracy. The various methodology used for clamping operation used in different application. The fixture step up for component is done manually for that more cycle time required for loading and unloading the material. There many type of fixtures and our project briefs about V – block fixture that we design and ...

One of the most commonly employed technologies of additive manufacturing is fused deposition modeling (FDM). FDM that employs polymer as the based material has proven to be a powerful method in rapid prototyping. Most of the FDM 3D printer feed stock material is Polylactic Acid (PLA), Acrylonitrile-Butadiene-Styrene (ABS), Nylon and etc. These limited choices of material for FDM printing had limited the option for engineers to create an object with a blend of different materials to create something unique where the object is being optimized not only in terms of shape but also the used of different materials to create an efficient product. Currently, the available 3D desktop printers on the market have a small build volume, mostly only enabling ...

Diamond based winding insulation for electrical machines - ABB Motors and Generators

Electrical conductors for electrical machines, such as electromotor or generator, are insulated for avoiding contact between the single coil and other conductive components of the electromotor for example the stator. For instance, the main wall insulation (e.g.: mica tape and impregnated resin) is used nowadays to insulate a conductor on full potential from the stator core on ground potential.

The principle of using mica tape and resin impregnation has not changed for almost a century and is well established to produce main wall insulation on a complex conductor shape and overall size, such as coils or Roebel bars for large electrical machines. However, these insulations have poor ...

The current invention is an improvement in basic measuring instruments. Like my other disclosure " Optical Illuminated Rule, " it is especially suited to the visually challenged. As with my other design the linear divisions are every 1/16". The uncluttered divisions make it easy to read. Despite the fact that the scale is in 1/16" divisions, it is possible to interpolate measurements to 1/64" without being taxing on the eyes.

The invention consists of a series of kerfs. The kerfs are spaced precisely 1/16" apart and the width of the slot is exactly 1/32". For a millimeter scale, a 1 mm slot every 2 mm is utilized. The invention resembles a comb in appearance.The scale can be read ...

The system design is divided into two sections, Transmitter and Quad Copter Section. Figure shows different blocks in transmitter section and quad copter section and the block connections. Transmitter and Quad Copter communicate with each other using 2.4GHz bandwidth signal in free space. The range of communication is limited. It is dependent on the gain of the transmitter and sensitivity of the receiver.

The transmitter block consists of signal sampler, frequency modulator and band pass filter. Signal sampler samples the signals at different intervals of time (multichannel operation) and frequency modulation is done and middle band frequency of 2.4GHz is selected for the band pass filter. Then the signal is transmitted in free space. The signal will be ...

This project is about the concept of a new engine called variable volume engine. In the variable volume four stroke engines, during the suction stroke there will be one volume and during other three strokes, there will be another volume. Thus the volume of variable volume engine is not constant.

The main aim of this type of engine is to achieve a combined advantage of variable compression ratio and supercharging. It is observed that overall efficiency of the engine is also increased. Thus variable volume engine has the advantage of increased volumetric efficiency due to supercharging and increased efficiency of the engine due to both supercharging and variable compression ratio. Thus the design and analysis of variable volume ...

The purpose of this project is to propose a new propeller-type climbing robot for climbing various types of structures which include significant obstacles, besides inspection of industrial vessels made of various materials, including non-ferromagnetic material. The inspection process includes capturing images of important spots which are prone to corrosion, as well as measuring the vessels' wall thickness.

The design mainly consists of two coaxial upturned propellers mounted on a mobile platform with four standard wheels. A new hybrid actuation system that consists of propeller thrust forces and standard wheel torques is considered as the adhesion system for this climbing robot. This system generates the required adhesion force to support the robot on the climbed surfaces.

Experimental tests to check ...

In a conventional Reciprocating Compressor there are a number of moving parts like the crank, connecting rod, belt drive system, and electric motor which contribute in frictional (mechanical) losses resulting in low efficiency. Also it is bulky in size and high maintenance required as it consists of motor, belt drive system, rotating parts. The capital and running cost of this type of compressor is high. All above disadvantages are overcome by an electromagnetic reciprocating air compressor. It works on the principle of electromagnetism. In this type of compressor almost all moving parts like the motor, belt drive system, crank, and connecting rod are eliminated from a conventional compressor. This result in higher efficiency than conventional reciprocating type compressor. It is ...
