Tray
A tray is a shallow platform designed for the carrying of items. It can be fashioned from numerous materials, including silver, brass, sheet iron, paperboard, wood, melamine, and molded pulp. Trays range in cost from inexpensive molded pulp trays which are disposable and inexpensive melamine trays used in cafeterias, to mid-priced wooden trays used in a home, to expensive silver trays used in luxury hotels. Some examples have raised galleries, handles, and short feet for support. Trays are flat, but with raised edges to stop things from sliding off them. They are made in a range of shapes but are commonly found in oval or rectangular forms, sometimes with cutout or attached handles with which to carry them. A more elaborate device is the tray table, which is designed to accommodate a tray, or to serve as a tray itself. There are two primary kinds of tray tables. The TV tray table is typically a small table, which may have legs that fold to allow it to be carried like a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TV Tray Table
A TV tray table, TV dinner tray, or personal table is a type of collapsible furniture that functions as a small and easily portable, folding table. These small tables were originally designed to be a surface from which one could eat a meal while watching television. The phrase tray-table can also refer to a fold-away tray, such as those found in front of airline seats. TV tray tables became popular in the 1950s as a way to hold food and beverage items while watching TV, the iconic item being a TV dinner. National advertising for TV tray tables first appeared in 1952, a full year before Swanson introduced the TV dinner in October 1953. A set of four TV tables were sometimes sold mounted on a small rack where they could be hung when not in use. This rack was popularly placed in a corner of the living room. The inventor of TV tray tables is unknown, but it may well be based on the Butler’s tray table. The original, popular models consisted of two pieces: a metal tray with grips m ...

Ute (vehicle)
A ute ( ), originally an abbreviation for "utility" or "coupé utility", is a term used in Australia and New Zealand to describe vehicles with a tonneau behind the passenger compartment, that can be driven with a regular driver's license. Traditionally, the term referred to vehicles built on passenger car chassis and with the cargo tray integrated with the passenger body (coupé utility vehicles). However, present-day usage of the term "ute" in Australia and New Zealand has expanded to include any vehicle with an open cargo area at the rear, which would be called a pickup truck in other countries. Etymology Historically, the term "ute" (short for ' utility vehicle') has been used to describe a 2-door vehicle based on a passenger car chassis, such as the Holden Commodore, Australian Ford Falcon, Chevrolet El Camino and Subaru BRAT. Australian-produced utes were traditionally rear-wheel drive and with the cargo tray integrated with the passenger body (as opposed to a pickup tr ...

Cutting (plant)
A plant cutting is a piece of a plant that is used in horticulture for vegetative (asexual) propagation. A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf pieces, called leaf cuttings, which produce both stems and roots. The scions used in grafting are also called cuttings. Propagating plants from cuttings is an ancient form of cloning. There are several advantages of cuttings, mainly that the produced offspring are practically clones of their parent plants. If a plant has favorable traits, it can continue to pass down its advantageous genetic information to its offspring. This is especially economically advantageous as it allows commercial growers to clone a certain plant to ensure consi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cafeteria
A cafeteria, sometimes called a canteen outside the U.S., is a type of food service location in which there is little or no waiting staff table service, whether a restaurant or within an institution such as a large office building or school; a school dining location is also referred to as a dining hall or lunchroom (in American English). Cafeterias are different from coffeehouses, although the English term came from the Spanish ''cafetería'', same meaning. Instead of table service, there are food-serving counters/stalls or booths, either in a line or allowing arbitrary walking paths. Customers take the food that they desire as they walk along, placing it on a tray. In addition, there are often stations where customers order food, particularly items such as hamburgers or tacos which must be served hot and can be immediately prepared with little waiting. Alternatively, the patron is given a number and the item is brought to their table. For some food items and drink ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molded Pulp
Molded pulp or molded fiber (also spelled as moulded pulp or moulded fibre) is a packaging material, that is typically made from recycled paperboard and/or newsprint. It is used for protective packaging or for food service trays and beverage carriers. Other typical uses are end caps, trays, plates, bowls and clamshell containers. For many applications, molded pulp is less expensive than expanded polystyrene (EPS), vacuumed formed polyethylene terephthalate (PET) and polyvinyl chloride (PVC), corrugation, and foams. Molded pulp is often considered a sustainable packaging material, as defined by the Sustainable Packaging Coalition, since it is produced from recycled materials, and can be recycled again after its useful life-cycle. Molded pulp products can be made waterproof with a spray or dip coating of wax. Types of molded pulp Several types of molded pulp can be manufactured by several processes. Thick-wall These products usually have wall thicknesses of 1.5 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airline Seat
An airline seat is a seat on an airliner in which passengers are accommodated for the duration of the journey. Such seats are usually arranged in rows running across the airplane's fuselage. A diagram of such seats in an aircraft is called an aircraft seat map. Features and amenities Seats are attached to rails underneath the floor which run along the aircraft fuselage. If the airline wants to reconfigure the seating, this is a minor operation. For passenger safety, all airline seats are equipped with seatbelts. Basic amenities Seats are frequently equipped with further amenities. Airline seats may be equipped with a reclining mechanism for increased passenger comfort, either reclining mechanically (usually in economy class and short-haul first and business class) or electrically (usually in long-haul first class and business class). Most aircraft also feature trays for eating and reading, either in the seatback which folds down to form a small table in most economy class ...

Silver
Silver is a chemical element with the Symbol (chemistry), symbol Ag (from the Latin ', derived from the Proto-Indo-European wikt:Reconstruction:Proto-Indo-European/h₂erǵ-, ''h₂erǵ'': "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal. The metal is found in the Earth's crust in the pure, free elemental form ("native silver"), as an alloy with gold and other metals, and in minerals such as argentite and chlorargyrite. Most silver is produced as a byproduct of copper, gold, lead, and zinc Refining (metallurgy), refining. Silver has long been valued as a precious metal. Silver metal is used in many bullion coins, sometimes bimetallism, alongside gold: while it is more abundant than gold, it is much less abundant as a native metal. Its purity is typically measured on a per-mille basis; a 94%-pure alloy is described as "0.940 fine". As one of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sowing
Sowing is the process of planting seeds. An area or object that has had seeds planted in it will be described as a sowed or sown area. Plants which are usually sown Among the major field crops, oats, wheat, and rye are sown, grasses and legumes are seeded and maize and soybeans are planted. In planting, wider rows (generally 75 cm (30 in) or more) are used, and the intent is to have precise; even spacing between individual seeds in the row, various mechanisms have been devised to count out individual seeds at exact intervals. Depth of sowing In sowing, little if any soil is placed over the seeds, as seeds can be generally sown into the soil by maintaining a planting depth of about 2-3 times the size of the seed. Sowing types and patterns For hand sowing, several sowing types exist; these include: * Flat sowing * Ridge sowing * Wide bed sowing Several patterns for sowing may be used together with these types; these include: * Regular rows * Rows that are ...

Plug (horticulture)
Plugs in horticulture are small-sized seedlings grown in seed trays filled with potting soil. This type of plug is used for commercially raising vegetables and bedding plants. Similarly plugs may also refer to small sections of lawn grass sod. After being planted, lawn grass may somewhat spread over an adjacent area. Plug plants are young plants raised in small, individual cells, ready to be transplanted into containers or a garden. "An alternative to field-grown transplants is the use of container-grown, or plug plants. Plug plants rooted in soil-less media offer the advantage of being grown under controlled environmental conditions that practically ensure that the..." Professionally raised vegetable/flowering plants in controlled conditions during their important formative period (the first 4–6 weeks) can help to ensure plant health and for plants to reach their maximum potential during the harvest/blooming period. Establishing a garden using plug plants is often easier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plastic
Plastics are a wide range of synthetic or semi-synthetic materials that use polymers as a main ingredient. Their plasticity makes it possible for plastics to be moulded, extruded or pressed into solid objects of various shapes. This adaptability, plus a wide range of other properties, such as being lightweight, durable, flexible, and inexpensive to produce, has led to its widespread use. Plastics typically are made through human industrial systems. Most modern plastics are derived from fossil fuel-based chemicals like natural gas or petroleum; however, recent industrial methods use variants made from renewable materials, such as corn or cotton derivatives. 9.2 billion tonnes of plastic are estimated to have been made between 1950 and 2017. More than half this plastic has been produced since 2004. In 2020, 400 million tonnes of plastic were produced. If global trends on plastic demand continue, it is estimated that by 2050 annual global plastic production will reach over 1,1 ...

Corrosion
Corrosion is a natural process that converts a refined metal into a more chemically stable oxide. It is the gradual deterioration of materials (usually a metal) by chemical or electrochemical reaction with their environment. Corrosion engineering is the field dedicated to controlling and preventing corrosion. In the most common use of the word, this means electrochemical oxidation of metal in reaction with an oxidant such as oxygen, hydrogen or hydroxide. Rusting, the formation of iron oxides, is a well-known example of electrochemical corrosion. This type of damage typically produces oxide(s) or salt(s) of the original metal and results in a distinctive orange colouration. Corrosion can also occur in materials other than metals, such as ceramics or polymers, although in this context, the term "degradation" is more common. Corrosion degrades the useful properties of materials and structures including strength, appearance and permeability to liquids and gases. Many ...

Brass Tray Inlaid With Silver, Egypt Or Syria, 19th Century, HAA I
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
