A fixed line style string trimmer head. A fixed-line string trimmer has a trimmer head that takes pre-cut line inserts. There is no wound spool of line in the trimmer head; the user instead feeds the pre-cut line in to the appropriate slots, making the trimmer easier to feed line into and troubleshoot than a bump feed system.

The Mitsubishi Astron or 4G5/4D5 engine, is a series of straight-four internal combustion engines first built by Mitsubishi Motors in 1972. Engine displacement ranged from 1.8 to 2.6 litres , making it one of the largest four-cylinder engines of its time.
It was developed specifically to be transversally installed in front-wheel-drive cars, unlike the preceding 4D5-series which remained in production for commercial vehicles. The 1.8 TD power figures are comparable to those of the 22 percent larger, 2.3 liter 4D55, with more low-down torque and while being much smoother. [ 6 ]
A ten-blade saw demonstrated by FirstEnergy in 2017. An aerial saw is a saw which is flown through the air. The aerial saw may also be known as a helicopter aerial saw.. Large aerial saws are flown by helicopter to trim trees in remote locations when they overgrow power lines, pipelines or other infrastructure.
The Astron was unveiled in Tokyo on December 25, 1969, after ten years of research and development at Suwa Seikosha (currently named Seiko Epson), a manufacturing company of Seiko Group. Within one week 100 gold watches had been sold, at a retail price of 450,000 yen ( US$1,250 (equivalent to $10,386 in 2023)) each (at the time, equivalent to ...
[7] [15] [16] Equivalently, by this definition, one au is "the radius of an unperturbed circular Newtonian orbit about the sun of a particle having infinitesimal mass, moving with an angular frequency of 0.017 202 098 95 radians per day "; [17] or alternatively that length for which the heliocentric gravitational constant (the product GM ...
A road verge is a strip of groundcover consisting of grass or garden plants, and sometimes also shrubs and trees, located between a roadway and a sidewalk. [1] Verges are known by dozens of other names such as grass strip, nature strip, curb strip, or park strip, the usage of which is often quite regional.
General parameters used for constructing nose cone profiles. Given the problem of the aerodynamic design of the nose cone section of any vehicle or body meant to travel through a compressible fluid medium (such as a rocket or aircraft, missile, shell or bullet), an important problem is the determination of the nose cone geometrical shape for optimum performance.
