Heavy Vehicle Crash Guard


The present invention relates to the safety impact guard for heavy vehicles. The problem of accident is a very acute in highway transportation. Traffic accident leads to loss of life and property. We cannot avoid accidents completely but impact of accident we can reduce by applying safety measures, safety instrument. Safety impact guard is one of the safety instruments which can reduce collision impact at rear end collision when accident occurs. Also provide safety against under ride crashes which is cause due to passenger vehicle collides with the truck or trailer. Proposed design of safety impact guard includes crushing element as force destroying material. Because of that when rear end collision occurs the force or energy or impact is destroyed due to crushing action.

“TEAM” for Organic Waste Treatment


The present invention relates to the treatment of organic solid wastes through anaerobic digestion within a short retention time of 7 days without mechanical mixing. The two stage process comprises of an Acidification phase in which organic content of solid waste is leached out to make a high strength liquid by decomposition of waste and a Methanation phase in which this high strength leachate is treated in a high rate Upflow Anaerobic Sludge Blanket reactor to produce biogas. The present invention produces non-flowable slurry after waste digestion and recycles water within the process resulting in reduced water consumption and aesthetic conditions around the plant.

Preferential Liquid Line Mechanical Switch over Device


With no concept of fixed water supply through the day, in India it becomes incumbent upon every house owner to not only use the direct supply of clean fresh water but store it in overhead tanks as well. However, the supply of water from two different sources requires an elaborate and complicated network of pipelines along with other associated accessories requiring high capital expenditure. Improper space utilization and loss of aesthetics are also a growing concern among urban population. The device functions in such a way that when fresh or preferred water supply is available, the supply from alternate source is stopped and fresh water is allowed to flow towards the outlet. On the other hand, when supply of fresh water is not available, device shifts supply from fresh water line to an alternate source such as an overhead tank. A transparent indicator with ball arrangement is provided to indicate changeover of water supply from fresh water to overhead water. The device operates based on pressure difference between different supplies.

Rotary Vane Reciprocating Compressor

Rotary vane reciprocating compressor

The present invention relates to a rotary vane reciprocating compressor and, more particularly it has positive displacement and aerodynamic compressors. The rotary vane reciprocating compressor (RVR) is a tradeoff between positive displacement and aerodynamic compressors, which provides higher mass flow rate and pressure ratios, whereas positive displacement compressors handle less mass flow rate at high pressure ratio while aerodynamic compressors handles high mass flow rate at less pressure ratio. It has large applications in various industries like Food industry, Tool Industry, Chemical Industry, Refrigeration, Central Air conditioning etc.
