摘要:
Substantially linear olefin polymers having a melt flow ratio, I10/I2, ≧5.63, a molecular weight distribution, Mw/Mn, defined by the equation: Mw/Mn≦(I10/I2)−4.63, and a critical shear stress at onset of gross melt fracture of greater than about 4×106 dyne/cm2 and their method of manufacture are disclosed. The substantially linear olefin polymers preferably have at least about 0.01 long chain branches/1000 carbons and a molecular weight distribution from about 1.5 to about 2.5. The new polymers have improved processability over conventional olefin polymers and are useful in producing fabricated articles such as fibers, films, and molded parts.

A networked boiler system includes a first boiler, at least one secondary boiler in operative connection with the first boiler and having a plurality of internal sub boilers, a boiler control connected to one of the first or secondary boilers, and an external control connected to one of the first or secondary boilers. The boiler control enables the first boiler to control a boiler parameter of the first boiler, the at least one secondary boiler, and the plurality of internal sub boilers of the at least one secondary boiler. A method of operating a networked boiler system includes the steps of connecting a first boiler to at least one secondary boiler, the secondary boiler including a plurality of nested sub boilers; connecting the first boiler to an external control; and with a boiler control connected to one of said first boiler and said at least one secondary boiler, controlling a boiler parameter of said first boiler, said at least one secondary boiler, and said plurality of nested sub boilers of said at least one secondary boiler.
摘要:
The present invention generally relates to improvements in chainsaws. In particular, the present invention relates to mechanisms for preventing the chain of a chainsaw from falling off the guide bar of the chain saw. According to one embodiment, a magnetic chainsaw chain retention mechanism comprising a magnetic guide bar is provided. The mechanism maintains the chain of a chainsaw on the chainsaw guide bar during use of the chainsaw. As heat expands the overall length of the chain while the chainsaw is running, a magnetic force attracts the chain to the guide bar thus preventing it from falling off. In another embodiment, a magnetic chain is provided, such that the chain remains attracted to the guide bar, wherein, a magnetic force attracts the chain to the guide bar if and when it expands thus preventing it from falling off the guide bar.
