The Wedco Nozzle is a CARB compliant spill-proof gas can nozzle. With the nozzle in place you can invert your gas can and it will not leak. Then simply push the nozzle lock and push the nozzle against the rim of the filling throat of the tank you're filling to start the flow of fuel. If you lift the nozzle away from the rim the flow stops.

A shaper is a reciprocating machine tool in which the ram moves the cutting towel backwards and forwards. A shaper is intended to produce flat surfaces. A planer is used to produce horizontal, vertical or inclined flat surfaces. A planer is used to work on heavy and large work pieces that cannot be accommodated on the table of a shaper. A slotter is also called a vertical shaper. The difference between a shaper and a slotter is the direction of the cutting action of the tools.

10 or above is common place. 11 is industry standard. So if you go into an elevator and it says it can hold a maximum of 20 persons with weight 1,500kg and that elevator has a factor of safety of 10, it can hold 200 persons or 15,000kg before it fails.

To find the formula in which to check the concentricity and position of something then one must calculate the position. In order to calculate the position, think of it as a function of velocity.

1 ksi is equal to 1,000 psi

§ Screw threads have better compression strength than other threads.

§ Due to low thread angle there is no radial pressure on nut.

§ Due to smaller angle, the lead of screw is less.

Bend meter is a type of pipe which are bend may be sharply or 90 degree .

In fluid mechanics we calculate the losses inside the pipe .in which losses are more.

A saw blade sharpening machine is used for sharpening the saw blade. Nowadays, the advantages of a saw blade sharpening machine includes the adjustment rod arrangement- the reasonable arrangement of rod makes the operator easily to adjust the tooth cutting angle , the backlash angle, tooth depth and tooth pitch. Furthermore, the thickness adjustment of saw blade, which obtained patent in many countries, that the blade was hold by two moving devices at the same time and move to the central of the machine for grinding; thus, there is no requirement to manually adjust the thickness of the blade. And it also can reduce the grinding noise.

Take SU-850 (which made by Eyan Co., Ltd - www.eyan.com) for example, it has a Continuously Variable Speed Drilling function. By using the converter to control the grinding speed, it can adjust the required grinding speed according to the tooth pitch difference.

Today, Saw Blade Sharpening Machine uses computer to simulate and design the professional tooth profile cam in order to make the grinding simpler, faster and more accurate.

Impingement plates are installed on the tube side of a bundle. It is between the tubes and the inlet nozzle and serves to slow down and/or disperse the liquid as it enters the exchanger. This prolongs the life of the tubes in this area which, in turn, extends the life of the bundle.

AH36 has a 51ksi min yield, so a Grade 50 ASTM steel like A-572 for plates or A-992 for w-beams would be equivalent.

Whirl velocity of a turbine is determined by how fast the turbine can turn when it is moving. This is a factor considered with airplane manufacturing. Whirl velocity is the number of times in a second that a turbine can rotate, moving at a given speed.

The operation of the pump, though a bit complex, is an interesting one. As shown in the figure, the circular ring, which accommodates the slippers is concentric with the central valve arrangement . Due to this, the piston doesn't have any relative reciprocating motion inside the cylinder. No oil is pumped or sucked in and although the pump is rotating no fluid is delivered, during this state. But this is only until the arrangement is concentric. As soon as the circular floating ring is pulled to the right the pistons in the cylinder undergo a reciprocating motion.

The lower piston moves inwards and discharges fluid through the lower port. The piston moves till the horizontal position and then moves outwards in the opposite direction, drawing in fluid through the upper ports. Thus in this way the top ports act as suction ports and the lower ports act as discharge ports. If the circular ring is pushed to the left direction, the suction and discharge ports are reversed.

All the variable displacement pumps are positive displacement pumps, with a constantly rotating arrangement and a variable discharge design. If the system has more than one pump, a non reversing locking gear is provided, which prevents the reverse operation that might take place at times when only one pump is operating. Moreover, the arrangement is such that as soon as the pump is stopped the locking gear would come into action .

GM500M: Mechanical and Material Requirements for Metric Externally Threaded Fasteners.

This standard covers the mechanical and material requirements for six property classes of carbon and alloy steel externally threaded metric fasteners in nominal thread diameters M1.6 to M36, inclusive, suitable for use in general engineering applications. Products included are bolts, screws, studs, U-bolts and sems and hardness of HRC39 max. Tapping screws, thread rolling screws, self drilling tapping screws and set-screws are NOT included.

The term "stud" as referred to herein applies to a cylindrical rod of moderate length, threaded on either one or both ends or throughout its entire length. It does not apply to headed, collared or similar products which are more closely characterized by requirements shown herein for bolts.

For specification purposes, this standard treats U-bolts as studs. Thus, wherever, the word "studs" appears, "U-bolts" is also implied. U-bolts covered by this standard are those used primarily in the suspension and related areas of vehicles. (Designers should recognize that the "U" configuration may not sustain a load equivalent to two bolts or studs of the same size and grade; thus actual load carrying capacity of U-bolts should be determined by saddle load tests.)

Requirements for the 6 property classes, 4.6, 4.8, 5.8, 9.8, and 10.9 are essentially identical with requirements given for these classes in ISO 898/1 and ASTM F568.
