| 20110145028 | ESTABLISHMENT AND SUSTENANCE OF KNOWLEDGE CONTINUITY PROCESS - A system and method for establishment and sustenance of Knowledge Continuity Process in a phase wise manner within an organization and/or among multiple organizations comprising knowledge drivers, business drivers, a leadoff team, a knowledge expert team, a knowledge administrator, knowledge distillation and diffusion, learning's from the past archive, business leagues, expert knowledge base, knowledge delivery characterized in that said system and method comprising: identifying a predetermined stage “n” of the organization; forming the leadoff team of individuals from the organization and from knowledge vendor; linking the knowledge drivers with the business drivers by said leadoff team; measuring a stage ‘n+1’ of the organization by individuals of the knowledge vendor; and providing a continuous improvement. | 06-16-2011 |
| 20090166162 | Contact Actuating Mechanism for Switching Device - According to one embodiment of the present invention, a contact actuating mechanism is provided with a rotary contact to make and break electrical contacts. An operating knob is connected an operating lever and to a connecting link through a U-shaped pin. The operating lever is engaged with a lock lever. The connecting link is also coupled to the rotary contact through a pivot so that the operating knob is moved to displace the connecting link to move the rotary contact to make and break with electrical contacts. | 07-02-2009 |
| 20090165349 | Integrated Contact Indication and Label Holder - The embodiment provide an assembly of contact indication and label holder using the same component for switching devices to provide safety indications to the technicians or end users. The assembly comprises of a tag and label holder. Tagging arrangement consists of an indication window for indication status of MCB i.e. ON/OFF and two hinges for holding label holder. The component also has two windows, which are intended for locking of label holder and groove for holding indicating paper. The user can write details on this indicating paper i.e. with which place it is connected and other details. The label holder has an inbuilt lens for giving contact indication a zooming effect for clear differentiation between red and green color of indication flag. | 07-02-2009 |
| 20090133862 | THREADED CHANNEL CLOSURE FOR TUBULAR HEAT EXCHANGER - Threaded channel closure for tubular heat exchanger comprising channel header wherein the gasket is provided at the shoulder of the channel, tongue of the diaphragm is provided to apply pressure on the gasket to achieve the sealed joint, outer compression ring provided at back side of the diaphragm and being loaded by push bolts, provided at the periphery of threaded lock ring, outer compression ring being supported by channel cover, which is kept in position by threaded lock ring, characterized in that, the channel header being provided with plurality of radial holes on its periphery, approximately at the centerline of the width of the outer compression ring in its assembled condition; the outer compression ring being provided with plurality of radial through holes matching the set of holes in number as well as angular position. | 05-28-2009 |
| 20090120608 | SEAL FOR TUBULAR HEAT EXCHANGER - Seal for tubular heat exchanger comprising groove with an inner edge; tongue of the diaphragm having front face extending in the radial direction and inner edge parallel to the axis of the channel; the face extending beyond the radial width of the groove in inward direction and overlapping the face of the shoulder of the channel in which the groove being provided. The tongue of the diaphragm being thus kept away from entering the groove; the diaphragm having flexibility to permit deflection of the tongue, the tongue of the diaphragm being loaded from outer side by the internal compression ring, the said internal compression ring being loaded in turn by the threaded push bolts/rods being fitted in the threaded holes on periphery of the threaded lock ring. This load is ultimately transferred to the joint between the gasket and face to achieve leak-proof joint. | 05-14-2009 |
| 20090095453 | SEALING ARRANGEMENT FOR INTERNAL TUBESHEET FOR TUBULAR HEAT EXCHANGERS - Sealing arrangement for an internal tubesheet for tubular heat exchangers comprising, a gasket fitted between a shoulder and a tubesheet, the gasket being made of spiral wound construction but without any metallic rings and without any locating groove in the adjoining components. On the outer side of the tubesheet, a channel box is provided with its inner face resting on a shoulder provided on an outer diameter of the tubesheet while the outer face of the channel box is reduced in diameter and arranged to align with the centerline of the push bolts, the outer face of the channel box resting against and attached to an annular ring and the push bolts being provided in threaded holes that reach up to the outer face of an internal flange. The push bolts, when tightened, load the annular ring, which in turn loads the gasketed joint through the channel box and the tubesheet. | 04-16-2009 |
