for high-speed precision scales, a load cell using electromagnetic force restoration emfr is appropriate. this kind of system charges an inductive coil, effectively floating the weigh bed in an electromagnetic field. when the weight is added, the movement of a ferrous material through that coil causes a fluctuation in the coil current .
a telescopic sight, commonly called a scope, is an optical sighting device that is based on a refracting telescope. it is equipped with some form of graphic image pattern a reticle mounted in an optically appropriate position in its optical system to give an accurate aiming point.
hyatt roller bearing company was a manufacturer of roller bearings from 1892 to 1916, when it was acquired by general motors.it continued as a distinct division of gm for many years. the company struggled at first, then entered a phase of profitable growth under the leadership of alfred p. sloan later president of general motors . the innovative design of hyatt's roller bearings made them .
inkjet printing is a type of computer printing that recreates a digital image by propelling droplets of ink onto paper and plastic substrates. inkjet printers are the most commonly used type of printer, 2 and range from small inexpensive consumer models to expensive professional machines.
high-precision components of non-standard values may have numerical information printed on them. difference between allowance and tolerance. the terms are often confused but sometimes a difference is maintained. see allowance engineering confounding of the engineering concepts of allowance and tolerance. clearance civil engineering
a kitchen knife is any knife that is intended to be used in food preparation. while much of this work can be accomplished with a few general-purpose knives – notably a large chef's knife , a tough cleaver , and a small paring knife – there are also many specialized knives that are designed for specific tasks.
in the same year, voxeljet celebrated the global premiere of its 3d printer vx1000 at euromold, the trade fair for tooling and mold-making, design and product development in frankfurt am main. by combining high performance and a large build space, this printing system was able to meet the growing requirements of industry.
common types of hydraulic pumps to hydraulic machinery applications are; gear pump: cheap, durable especially in g-rotor form , simple. less efficient, because they are constant fixed displacement, and mainly suitable for pressures below 20 mpa 3000 psi .
the g3 g ewehr 3 is a 7.62×51mm nato, select-fire battle rifle developed in the 1950s by the german armament manufacturer heckler & koch h&k in collaboration with the spanish state-owned design and development agency cetme centro de estudios técnicos de materiales especiales . 2 design details. 3.1 models made under license.
the pcb is clamped, and the nozzles pick up individual components from the feeders/trays, rotate them to the correct orientation and then place them on the appropriate pads on the pcb with high precision. high end machines can have multiple conveyors to produce multiple same or different kind of products simultaneously. inspection
the kyropoulos process is a method of bulk crystal growth used to obtain single crystals. the process is named for spyro kyropoulos wikidata , who proposed the technique in 1926 as a method to grow brittle alkali halide and alkali earth metal crystals for precision optics.
the seal is designed to have a point contact between the o-ring and sealing faces. this allows a high local stress, able to contain high pressure, without exceeding the yield stress of the o-ring body. the flexible nature of o-ring materials accommodates imperfections in the mounting parts.
invar is used where high dimensional stability is required, such as precision instruments, clocks, seismic creep gauges, television shadow-mask frames, valves in engines and large aerostructure molds. one of its first applications was in watch balance wheels and pendulum rods for precision regulator clocks.
a throatless shear is a cutting tool used to make complex strht and curved cuts in sheet metal. the throatless shear takes its name from the fact that the metal can be freely moved around the cutting blade it does not have a throat down which metal must be fed , allowing great flexibility in shapes that can be cut.
the m249 provides infantry squads with the high rate of fire of a machine gun combined with accuracy and portability approaching that of a rifle. the m249 is gas operated and air-cooled. it has a quick-change barrel, allowing the gunner to rapidly replace an overheated or jammed barrel.
