Traditional pressure-boundary piping gaskets, such as pipe flanges and valve body-to-bonnet joints, can leak due to many factors. Chief among these are (i) improper initial gasket seating stress (GSS) sufficient to form a seal and (ii) failure to maintain the initial GSS in-service due to creep relaxation of the gasket sealing material over time.
GSS is a function of the design pressure for the system. To obtain the desired GSS, the required torque on the closure fasteners, fastener number and diameter, the 'nut' or 'K' factor pertaining to various factors including friction, are all taken into consideration. This produces ...

My name is Troy McCurry.I was a Tool Designer for the Jacobs Manufacturing Co. from 1993 thru 1998. In 1998 Jacobs Manufacturing Co. moved all production off-shore. 300 American jobs left as well.I can only assume this was impacted by the cost of producing a drill chuck in the USA and competing with other companies manufacturing drill chucks off-shore.
Now ask yourself what if it was not that way?
Now we have the “Little Mac” style of Power drill chucks. This product is covered under patent # 6,637,756. From the commonality of parts to the compact styling and reliability ...

Our reliance on fossil fuels has been a problem for generations and in the near future we will see a global crisis resulting from this dependence. The barriers to our society moving beyond fossil fuels to renewable sources of energy include both the cost and the inefficiency of the existing renewable energy systems. The ideas that I am presenting will address these issues.
Wind farms in their current incarnation are effective in only one direction and they are massive in size. To improve the efficiency of the conventional wind turbines, I propose a closed design that incorporates a system ...
A new approach for enhancing joints’ properties based on the epoxysiliconorganic glue by simultaneously integrating micro- and nanosized fillers into a glue formulation has been proposed. It has been revealed that it results in a more than threefold increase in the glue joint’s thermoresistability.
The toughness of the found glue seam structure should raise compared with the standard formulation due to the fact that nanoparticles tend to fill the free space between microparticles of the typical microfiller.
Fig. 1 (a,b) illustrates how micro- and nanoparticles may increase the toughness of a glue seam when simultaneously introduced into a glue ...
If anything good could be said about the oil spill in the Gulf of Mexico, it would be that it has alerted us to our unpreparedness. It is my intention to remedy that with this device.
The device is designed so that when it is lowered into an open pipe and its threaded shaft is rotated, it will expand to grip the pipe and plug the open end. It requires rotational force alone to operate and it is designed in a way that reduces the chance of malfunction. It is also easy to use, and therefore less subject to ...

In normal Scuba device when the tanks are emptied we have to go to land to charge the tank with compressed air which allows less time to be spent underwater.
This Equipment allows more time to be spent in water by charging the tank in the sea itself. The Equipment consist of air compressor, battery and tank.Whenever the air in the tank is emptying the diver comes to the surface and fill the tank with air by using compressor rather than going to charging station on the shore. This similar to current Scuba equipment except it has compressor ...
The Energy Information Administration of the US Department of Energy reported the electrical consumption of the US in 2001 as 1,140 billion kilo-watts/hr.
16% of the reported usage is air-conditioning and refrigeration or 182.4 billion Kw/hr.
An article in the Refrigeration News reported that an estimated 30% of serviced AC was improperly charged or installed.
If an average unit size is 2.9 Kw (for 4000 hours), that is about 15,724,138 units out of 107 million US households. The article eludes to the fact that about 4.7 million units at 2.9Kw, are using more power than required.
If the units ...

It is in a form of a wristwatch which is tied over the wrist of all passengers individually at the security check. It is locked on the wrist and can be opened using a password only at disembarkation point. This system contains an injectable tranquilizer inside it. If the passenger tries to remove it, the injection system operates at once and tranquilizes the person. This system can also be operated with the help of global satellite network anywhere in the world, on ground level or when in the air. It can even be operated manually by any crew within ...

Power system automation is something that will prevent electrical thefts, accidents and also provide automatic billing and load management. In this work we have actually built three systems -- a basic system, enhanced system and further enhanced system. The last two systems have communication capabilities which will transfer meter readings from a subscriber to the main sub station. During this process electric thefts or accidents are detected by performing computation on these readings and appropriate action is taken. Signals are transmitted using only one wire and hence on total we have three wires including the neutral and the power line. ...
* Here is a product that speeds and improves work, manufacturing, or scientific research processes.
* The novel backpressure regulator that opens or "cracks" at low pressures in chemical environments is the "Magnetic Backpressure Regulator".
* The novel Magnetic Backpressure Regulator keeps a constant pressure on items upstream of it. It is a normally-closed valve that opens when the pressure goes above a threshold value, thus maintaining a constant backpressure.
* The novel Magnetic Backpressure Regulator comprises a conduit for channelling a fluid under pressure, a regulator for exhausting the ...
