it's the determination of which machine is idle or should perform certain tasks.

The use of gunpowder started in Europe during the late 13th century. It was Roger Bacon, who introduced gunpowder and in 1353 the first gunpowder cannon was invented by Berthold Schwarz.

There are approximately six million fire hydrants installed in the US. The first fire hydrants, called fire plugs, were in use beginning in the 17th century.

CK Jeans denim fabric feels very good because it contains both cotton and stretch material that causes it to fit well. These jeans can be quite expensive, but they look great on many body types.

1 psi = 27.68 in. H2O so 15 (27.68)= 415.2 in H2O

classification timber is based on diff rent purpose

Moulten plastic is injected at high pressure into an injection mould tool. The plastic cools inside the tool and takes the inverse form of the cavity machined into the tool. The process takes several stages: 1/ Closing - The tool is closed (the 2 halves are brought together) and clamped under high force. This force is maintained until the end of step 4 2/ Injection - Plastic is injected into the tool at pressure (up to about 2000 bar thus high clamping force required in step 1) 3/ Hold Pressure - Plastic shrinks as it solidifies. The pressure of moulten plastic is maintained for a period of a few seconds (depends on part) to keep filling the tool as this happens. 4/ Cooling - The tool remains closed whilst the plastic cools and becomes solid enough to be ejected. 5/ Opening - The tool is opened. 6/ Ejection - The part is ejected from the tool. The process continues at step 1. The total time for these 6 steps is usually between about 8 seconds and 3 minutes depending on the thickness of the part being moulded. (Steps 3 & 4 take much longer with thick parts.) Times of 20 to 40 seconds are typical.
Plastic injection molding is a complex and intricate process. Simply put, the injection molding uses a plunger to force hot, liquid plastic into a mold cavity.

Retrievable corrosion probes is meant for high pressure (3600 to 6000 psig).

Retractable corrosion probes is meant for pressure about 1500 psig.

It is possible to apply paint to galvanized steel. It must first be primed with a special primer. You must use a paint designed for this purpose.

Tungsten has a very high melting point that's around 3500degrees, its used in radioactive equipment like x-ray machines so it can withstand electron beams and what not....

They are currently made from aluminum. Historically, steel or brass was used.[1]

It is actually FIAT's Betim plant in Brazil.

It doesn't appear regular epoxy paint will work for inhibiting mold growth, but there are epoxy wall coatings that have a mold inhibitor in them. One of them is called The Basement Doctor Epoxy.

Butt joints in furniture making is the joining of two pieces of wood, end to end without the assistance of a joining device such as fingers, dovetails, or box joining. Generally, the use of dowels or biscuits is encouraged to improve the strength of the joint. A butt joint without such reinforcement devices is the weakest form of joint, and may fail if stressed.

Both Profibus(PA) and FF H1 started off in the same working group and have much in common: the physical medium on which both operates is in accordance to IEC 1152-2 intrinsically saftey. Profibus DP which is used in 90% of profibus applications use either RS-485 or an Optical fibre link. When comparing thir implementation on the data layer in Profibus the input and output blocks are located in the controller itself. The controller(master) fetches the data from the field instruments. However no control blocks are moved into instruments. In FF, the input blocks along with the control block are moved into instruments consequently implementing 'control in the field'. The number of devices per segment/loop also varies in Profibus VS FF H1, with the later having a max of 127 and being limited to 32 due to bottleneck of RS-485 and FF to 31 itself. But practically FF system recommends no more than 12 devices per loop with a cycle time of 0.5s while profibus supports 24 with a delay of 400ms.

if you have a base line of say 10FT then all you have to do is go to your stop point and count back say 3FT then go back to you stop point and go up 4FT then all you have to do is make your 5FT mark from the 3FT to the 4FT and then you should have a right angle...

in wire cut, a wire is passed through a metal or is placed next to it. the wire works as one of the electrodes while the work piece would be the other one; using andielectric liquid to isolate the wire from the work piece. the electricity is conducted in the wire. as the wire gets closer to the work piece the electricity (electrons) tend to jump from the wire to the work piece in order to create a complete electrical circuit that's when a spark is formed. the dielectric helps us by isolating the wire from the work piece as long as it can, so we can have enough difference in potential between two electrodes before the spark is formed, it works like capacitor stopping the current from going through it until it collapses at a potential and enough current passes through at once. A collateral effect of this passage of current is that material is removed from both the electrodes.
