History Early years In the 1970s, James Dyson bought a The Hoover Company, Hoover Junior vacuum cleaner, which lost suction after a period of use. Frustrated, Dyson emptied the disposable paper bag to try to restore the suction but this had no effect. On opening the bag to investigate, he noticed a layer of dust inside, clogging the fine material mesh. Later, Dyson was working on his ballbarrow at ...

Trade Name
A trade name, trading name, or business name is a pseudonym used by companies that do not operate under their registered company name. The term for this type of alternative name is fictitious business name. Registering the fictitious name with a relevant government body is often required. In a number of countries, the phrase "trading as" (abbreviated to t/a) is used to designate a trade name. In the United States, the phrase "doing business as" (abbreviated to DBA, dba, d.b.a., or d/b/a) is used,Pinkerton's, Inc. v. Superior Court'', 49 Cal. App. 4th 1342, 1348-49, 57 Cal. Rptr. 2d 356, 360 (1996) (collecting cases and explaining term of art "doing business as" (DBA)). among others, such as assumed business name or fictitious business name. In Canada, "operating as" (abbreviated to o/a) and "''trading as''" are used, although "''doing business as''" is also sometimes used. A company typically uses a trade name to conduct business using a simpler name rather than using their for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sawmill
A sawmill (saw mill, saw-mill) or lumber mill is a facility where logging, logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes (dimensional lumber). The Portable sawmill, "portable" sawmill is simple to operate. The log lies flat on a steel bed, and the motorized saw cuts the log horizontally along the length of the bed, by the operator manually pushing the saw. The most basic kind of sawmill consists of a chainsaw and a customized jig ("Alaskan sawmill"), with similar horizontal operation. Before the invention of the sawmill, boards were made in various manual labour, manual ways, either wood splitting, rived (split) and plane (tool), planed, hewing, hewn, or more often hand sawn by two men with a whipsaw, one above and another in a saw pit below. The earliest known mechanical mill is the Hierapolis sawmill, a Roman water-powered stone mill at Hierapolis, Asia M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centrifugal Force
Centrifugal force is a fictitious force in Newtonian mechanics (also called an "inertial" or "pseudo" force) that appears to act on all objects when viewed in a rotating frame of reference. It appears to be directed radially away from the axis of rotation of the frame. The magnitude of the centrifugal force ''F'' on an object of mass ''m'' at the perpendicular distance ''ρ'' from the axis of a rotating frame of reference with angular velocity is F = m\omega^2 \rho. This fictitious force is often applied to rotating devices, such as centrifuges, centrifugal pumps, centrifugal governors, and centrifugal clutches, and in centrifugal railways, planetary orbits and banked curves, when they are analyzed in a non–inertial reference frame such as a rotating coordinate system. The term has sometimes also been used for the '' reactive centrifugal force'', a real frame-independent Newtonian force that exists as a reaction to a centripetal force in some scenarios.

Cyclonic Separation
Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of air filter, filters, through vortex separation. When removing particulate matter from liquid, a hydrocyclone is used; while from gas, a gas cyclone is used. Rotational effects and gravity are used to separate mixtures of solids and fluids. The method can also be used to separate fine droplets of liquid from a gaseous stream. Operation A high-speed rotating (air)flow is established within a cylindrical or conical container called a cyclone. Air flows in a Helix, helical pattern, beginning at the top (wide end) of the cyclone and ending at the bottom (narrow) end before exiting the cyclone in a straight stream through the center of the cyclone and out the top. Larger (denser) particles in the rotating stream have too much inertia to follow the tight curve of the stream, and thus strike the outside wall, then fall to the bottom of the cyclone where they can be removed.

Powder Coating
Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint, which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then Powder coating#Curing, cured under heat or with ultraviolet light. The powder may be a thermoplastic or a thermosetting polymer. It is usually used to create a thick, tough finish that is more durable than conventional paint. Powder coating is mainly used for coating of metal objects, particularly those subject to rough use. Advancements in powder coating technology like UV-curable powder coatings allow for other materials such as plastics, composites, Carbon-fiber reinforced polymer, carbon fiber, and medium-density fibreboard (MDF) to be powder coated, as little heat or oven dwell time is required to process them. History, properties, and uses of powder coating The powder coating process was invented around 1945 by Daniel Gustin and received US Patent 2 ...

Fusion Bonded Epoxy Coating
Fusion bonded epoxy coating, also known as fusion-bond epoxy powder coating and commonly referred to as FBE coating, is an epoxy-based powder coating that is widely used to protect steel pipe used in pipeline construction from corrosion. It is also commonly used to protect reinforcing bars (though being phased out as of 2005) and on a wide variety of piping connections, valves etc. FBE coatings are thermoset polymer coatings. They come under the category of ''protective coatings'' in paints and coating nomenclature. The name ''fusion-bond epoxy'' is due to resigning cross-link and the application method, which is different from a conventional paint. In 2020 the market size was quoted at 12 billion dollars. The resin and hardener components in the dry powder FBE stock remain unreacted at normal storage conditions. At typical coating application temperatures, usually in the range of , the contents of the powder melt and transform to a liquid form. The liquid FBE film wets and flo ...

Ballbarrow
The Ballbarrow was a variation of the wheelbarrow design, by James Dyson released in 1974 in the UK. It featured a moulded plastic wikt:hopper, hopper on a steel frame and a spherical plastic wheel, allowing increased manoeuvrability. Dyson said that the surface area of the ball, larger than that of a conventional design, made the ballbarrow easier to use in soft soil and more laterally stable with heavy loads on uneven ground. The original design featured a galvanised steel or copper hopper, forming integral rear legs. Conventional barrows use a bend in the frame to form these legs. Later the design was changed to a plastic hopper, with an optional clip on height-extension piece. The Ballbarrow won the Building Design Innovation Award in 1977. Dyson continued with the ball-wheel concept in his design for the Trolleyball boat launcher in 1978, and the List of Dyson products#DC15, DC15 vacuum cleaner in 2005. Dyson claimed his failure to maintain control of his invention by assign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HVAC
Heating, ventilation, and air conditioning (HVAC ) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and healthy building conditions are regulated with respect to temperature and humidity, using fres ...
