NNPB = Narrow Neck Press and Blow.
This is a glass bottle forming process,wherein very light weight glass bottles are made compared to the traditional blow and blow process of making glass bottles.
NNPB bottles are lighter by around 30% compared to Blow and Blow process,and the bottles produces have evenly distributed glass,and so stronger than blow and blow glass bottles.
But this process requires hitech glass forming machinery,expensive mould items and very skilled labour.
Most of the renowned glass bottle making companies are now making bottles using this technology.
What does the schematic drawing look like for an auto-retract clamp and drill hydraulic circuit?
If one takes a look at the schematic drawing of an auto-retract clamp and drill hydraulic circuit, one will see the single-acting clamp cylinder and quarter of an inch operator control valve. It also has double-acting work cylinder, as well as quarter inch air sequence valve.
What is the difference between injection molding and transfer molding?
The difference is within the machine and process
The presses used for injection molding are horizontally operated with a unique material delivery system. The thermoset compound is fed and injected with a high speed reciprocating screw, or a plunger system that reduces glass degradation for better part strength. The major advantages of injection molding:
The presses used for transfer molding are vertically operated and equipped with a hydraulic transfer system and controls. The thermoset compound is loaded into a chamber known as the transfer pot. The mold is then closed and a transfer plunger forces the compound from the pot through the runner system and gates into the mold cavities. The major advantages of transfer molding:

What might be causing a hissing noise in a shock absorber during rebound?
A cracked air cylinder could cause a hissing sound in a shock absorber during rebound. Another possible cause could be the seal.
How do you calculate the invert elevation of a manhole?
Invert elevations can usually be found directly on as-built drawings of the sewer facility. The simplest way to calculate an invert elevation of a manhole is to measure the depth of the manhole from the surface to the pipe invert. The invert elevation equals the ground or rim elevation minus this depth.
If you do not know the rim elevation or invert elevation, a surveyor must measure the invert and/or rim elevation with reference to a nearby elevation benchmark (see: http://commons.wikimedia.org/wiki/Image:Elevation_Benchmark.jpg). Also, upstream and downstream invert elevations in a manhole typically differ by about 0.1 feet.
(engineering) A small-flow valve connected to a fluid process vessel or line for the purpose of bleeding off small quantities of contained fluid.
some one that deal in or makes jewellery,my father is one so i know,and it kind of obis if u know enof English and if u don't then good luck with ur life....:|
It depends on which Directive the vessel has to be compliant with. For instance, to comply with CE/PED, the test pressure shoud be 1.43 times the maximum operating pressure.
Significance of grain size analysis?
grain size analysis is used to accertain the various sizes that are available in a particular sample of soil since it is required to calculate the strenght of concrete mix and also the king of soil that the sample is.
How are Allen head bolts made?
First, a round bar is cut to the correct length of the bolt. A hex head is then hot forged onto the end of the cut rod. Then, high speed blades are used to cut the correct threading onto the bolt.
Why the gas engine hunting while running?
Regarding to my experience ,there are some possible cause for this issue : 1. Engine : Death Ignition /Spark Plug,which is lead to unbalance power on crank shaft.Long term operation in this situation might lead to broken/damage shaft. 2.Low pressure on 1 or more combustion chamber,due to leaking on piston rings.It is also could make unbalance on mechanical operation of the engine. 3.False setting on Actuator,which lead the false response/compenstion time of the fuel demand. 4.Broken governor ( false setting) : try to adjust the gain and stability setpoint. Please note : Adjust engine stability first by set-up gain & Stability.After stability obtain,adjust the speed to the nominal speed ( ie : 1500 rpm).Initial speed setting is the factory setting,so it won't far enough from your nominal setting point. 5.Bent actuator linkage ,it is causing the compenstaion curve is not in good order.Please check for the linkage. 6.In case of the engine is the prime mover of a generator,electrical cause might lead to this situation ; ie : unbalance of excitation on the field winding.The possible source could be ,unbalance value of the insulation which lead on unbalance magnetic flux. Hints : on AVR ; try to adjust STAB ( Stability ) setpoint if available. 7.Ground faulty on speed input device ( MPU = Magnetic Pick-Up Unit ) .Check the +/Ground impedance value and compare to the -/Ground impedance value.It should not to be zero.That's why it is better to have coaxial signal cable on this input,to avoid any ground noise.If you have power analyzer,check for the signal noise. Last,but I hope it is not the last clue is mechanical damage on flywheel,which leads to bad signal from MPU.manually rotate the crankshaft and see the condition of the flywheel for any mechanical damage posibility. For initial action : try to disconnect the engine from the driven load.See; if the hunting is gone ,the hunting must be comes from the load side.But if the hunting still present ,it must be comes from the engine itself.

What will be next step in your millwright career?
Millwright works with heavy equipment in many different types of fields such as manufacturing and construction. Once they are done receiving the minimum of a high school diploma, for a millwright is to find a mentor in the field and work as apprentice to gain valuable experience.
How do cotton picking machines work?
The basic principal of the cotton picker has remained unchanged from the days it was pulled by horses. The picker has a drum mounted vertically that has rows of spindles. The spindles have gear teeth on the base and are pointed with tiny teeth. The drum rotates the Spindles around from front to back, while the spindles are rotated on their axis. The Spindles have small teeth that grab the cotton as they rotate to the front of the drum. When the drum rotates to the aft position, the Spindles are rotated in opposite direction and the cotton is brushed off of them, falling into a bin.

What homemade additive can you add to gasoline to get better mileage?
Fuel additives are used to improve an automobile's environmental performance and increase its mileage. Some homemade fuel additives are ethanol and a mixture of acetone, xylene and cycle oil.
pipe a fill 1/4th part in 7 mins and pipe b in 7.5 mins hence both tank will fill 1/4th of tank in 7+7.5/4 = 3.6 mins

Can metal bottle caps be recycled?
Yes, they are usually made of thin aluminum, and can be recycled just like aluminum cans.
