Tool Chest
A toolbox (also called toolkit, tool chest or workbox) is a box to organize, carry, and protect the owner's tools. They could be used for trade, a hobby or DIY, and their contents vary with the craft. Types A toolbox could refer to several types of storage to hold tools. It could mean a small portable box that can carry a few tools to a project location or a large storage system set on casters. Modern toolboxes are predominantly metal or plastic. Wood was the material of choice for toolboxes built beginning in the early 19th century. Toolboxes can be mainly divided as 5 types. They are: * Plastic * Steel * Aluminium * Waterproof * Cantilever Small portable toolboxes are sometimes called hand boxes or portable tool storage. Most portable toolboxes have one handle on top and a lid that opens on a hinge. Many have a removable tote tray that sits on a flange inside the lip of the box, with a single larger compartment below. The tote tray helps organize smaller parts a ...

20060513 Toolbox
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler". Six is a con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Repair Kit
The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure, and supporting utilities in industrial, business, and residential installations. Over time, this has come to include multiple wordings that describe various cost-effective practices to keep equipment operational; these activities occur either before or after a failure. Definitions Maintenance functions can defined as maintenance, repair and overhaul (MRO), and MRO is also used for maintenance, repair and operations. Over time, the terminology of maintenance and MRO has begun to become standardized. The United States Department of Defense uses the following definitions:Federal Standard 1037C and from MIL-STD-188 and from the Department of Defense Dictionary of Military and Associated Terms * Any activity—such as tests, measurements, replacements, adjustments, and repairs—intended to retain or restore a func ...

Gang Box
Gangbox (also gang box) is a colloquial term utilized in the construction industry, referring to a toolbox A toolbox (also called toolkit, tool chest or workbox) is a box to organize, carry, and protect the owner's tools. They could be used for trade, a hobby or DIY, and their contents vary with the craft. Types A toolbox could refer to several typ ... or workbox that can be accessed by multiple workers. Origin The word gangbox may have been derived for several reasons. Firstly, "gang" can be used to refer to the group of tools utilized for a particular project, thus making the receptacle in which they are stored the "gang box". Secondly, a gang can refer to a group of workmen or tradesmen, hence the name for where their materials or tools are kept is the gang's box. The boxes are known for their rugged design and tough security. Sailors would store important tools in a secure lockers that were easily accessed by the crew but tough enough to survive unwanted access from ...

Global Variable
In computer programming, a global variable is a variable with global scope, meaning that it is visible (hence accessible) throughout the program, unless shadowed. The set of all global variables is known as the ''global environment'' or ''global state.'' In compiled languages, global variables are generally static variables, whose extent (lifetime) is the entire runtime of the program, though in interpreted languages (including command-line interpreters), global variables are generally dynamically allocated when declared, since they are not known ahead of time. In some languages, all variables are global, or global by default, while in most modern languages variables have limited scope, generally lexical scope, though global variables are often available by declaring a variable at the top level of the program. In other languages, however, global variables do not exist; these are generally modular programming languages that enforce a module structure, or class-based object-oriente ...

Subroutine
In computer programming, a function or subroutine is a sequence of program instructions that performs a specific task, packaged as a unit. This unit can then be used in programs wherever that particular task should be performed. Functions may be defined within programs, or separately in libraries that can be used by many programs. In different programming languages, a function may be called a routine, subprogram, subroutine, method, or procedure. Technically, these terms all have different definitions, and the nomenclature varies from language to language. The generic umbrella term ''callable unit'' is sometimes used. A function is often coded so that it can be started several times and from several places during one execution of the program, including from other functions, and then branch back (''return'') to the next instruction after the ''call'', once the function's task is done. The idea of a subroutine was initially conceived by John Mauchly during his work on ENIAC, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shopping Carts
A shopping cart (American English), trolley (British English, Australian English), or buggy (Southern American English, Appalachian English), also known by a variety of other names, is a wheeled cart supplied by a shop or store, especially supermarkets, for use by customers inside the premises for transport of merchandise as they move around the premises, while shopping, prior to heading to the checkout counter, cashiers or tills. Increasing the amount of goods a shopper can collect increases the quantities they are likely to purchase in a single trip, boosting store profitability. In many cases customers can then also use the cart to transport their purchased goods to their vehicles, but some carts are designed to prevent them from leaving either the store or the designated parking area by magnetically locking the wheels. In many places in the United States, Canada and the United Kingdom, customers are encouraged to leave the carts in designated areas within the parking l ...

Tradesperson
A tradesman, tradeswoman, or tradesperson is a skilled worker that specializes in a particular trade (occupation or field of work). Tradesmen usually have work experience, on-the-job training, and often formal vocational education in contrast to an apprentice, who is learning the trade. As opposed to a craftsman or an artisan, the occupation of a tradesman is not necessarily restricted to manual work. History In Victorian England: :The terms "skilled worker," "craftsman," "artisan," and "tradesman" were used in senses that overlap. All describe people with specialized training in the skills needed for a particular kind of work. Some of them produced goods that they sold from their own premises (e.g. bootmakers, saddlers, hatmakers, jewelers, glassblowers); others (e.g. typesetters, bookbinders, wheelwrights) were employed to do one part of the production in a business that required a variety of skilled workers. Still others were factory hands who had become experts in some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyester
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less Fireproofing, fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Textile
Textile is an umbrella term that includes various fiber-based materials, including fibers, yarns, filaments, threads, different fabric types, etc. At first, the word "textiles" only referred to woven fabrics. However, weaving is not the only manufacturing method, and many other methods were later developed to form textile structures based on their intended use. Knitting and non-woven are other popular types of fabric manufacturing. In the contemporary world, textiles satisfy the material needs for versatile applications, from simple daily clothing to bulletproof jackets, spacesuits, and doctor's gowns. Textiles are divided into two groups: Domestic purposes onsumer textilesand technical textiles. In consumer textiles, aesthetics and comfort are the most important factors, but in technical textiles, functional properties are the priority. Geotextiles, industrial textiles, medical textiles, and many other areas are examples of technical textiles, whereas clothing and ...

Medical Bag
A medical bag (doctor's bag, physician's bag) is a portable bag used by a physician or other medical professional to transport medical supplies and medicine. Traditionally, the medical bag was made of leather, opened on the top with a split-handle design. During the American Civil War, physician's medical saddle bags were used. Modern medical bags are made of various materials and come in various designs that can include many pockets, pouches, and zippered or hook-and-loop openings. Indigenous North American medicine men and shamans use a medicine bag. A battle bag is used in the military. Popular culture The original Wonder Woman comic book character carried a medical bag (as a Lt. Nurse) in which she carried her costume and accessories. In 1955, the MV Joyita charter boat was found partially submerged after being missing for 5 weeks. Among the items found onboard was a doctor's bag containing a stethoscope, a scalpel, and four lengths of blood-stained bandages. In the tele ...

Apron
An apron is a garment that is worn over other clothing to cover the front of the body. The word comes from old French ''napron'' meaning a small piece of cloth, however over time "a napron" became "an apron", through a linguistics process called rebracketing. It may have several purposes, typically as a functional accessory that protects clothes and skin from stains and marks. However, other types of aprons may be worn as a decoration, for hygienic reasons, as part of a uniform, or as protection from certain dangers such as acid, allergens or excessive heat. It can also be used at work stations to hold extra tools and pieces or protect from dust and unwanted materials. As a top layer that covers the front body, the apron is also worn as a uniform, adornment, ceremonial garb (e.g. Masonic apron) or fashion statement. Apron styles can be practical, fashionable, and sentimental. Apron styles There are many different apron forms depending on the purpose of the apron. A basic di ...
