Royal Air Force officer with 1958 pattern holster. A standard set of 1958 Pattern webbing as issued to most British personnel consisted of a belt, a yoke that supported the attachment of a shovel or pick, two ammunition pouches to carry magazines for the L1A1 self-loading rifle, Sterling submachine gun, or L4A1-A9 machine gun, linked 7.62mm ammunition for the L7A1/A2 general-purpose machine ...
A beltweigher or belt weigher, more commonly known as a belt scale, is a piece of industrial control equipment used to measure the mass and flow rate of bulk material traveling over a conveyor belt. [1] Invented by Herbert Merrick in the early 1900's, belt weighers are commonly used in plants and heavy industries, such as mining. [2]
These checkweighers are known also as belt weighers, in-motion scales, conveyor scales, dynamic scales, and in-line scales. In filler applications, they are known as check scales. Typically, there are three belts or chain beds: An infeed belt that may change the speed of the package and to bring it up or down to a speed required for weighing.

People demonstrating a Schmidt–Cassegrain telescope at a sidewalk gathering. The Schmidt–Cassegrain design is very popular with consumer telescope manufacturers because it combines easy-to-manufacture spherical optical surfaces to create an instrument with the long focal length of a refracting telescope with the lower cost per aperture of a reflecting telescope.
The Burroughs B6x00-7x00 instruction set includes the set of valid operations for the Burroughs B6500, [1] B7500 and later Burroughs large systems, including the current (as of 2006) Unisys Clearpath/MCP systems; it does not include the instruction for other Burroughs large systems including the B5000, B5500, B5700 and the B8500.
The atomic length scale is ℓ a ~ 10 −10 m and is given by the size of hydrogen atom (i.e., the Bohr radius, approximately 53 pm).; The length scale for the strong interactions (or the one derived from QCD through dimensional transmutation) is around ℓ s ~ 10 −15 m, and the "radii" of strongly interacting particles (such as the proton) are roughly comparable.
The Taylor microscale is the intermediate length scale at which fluid viscosity significantly affects the dynamics of turbulent eddies in the flow. This length scale is traditionally applied to turbulent flow which can be characterized by a Kolmogorov spectrum of velocity fluctuations. In such a flow, length scales which are larger than the ...
