A hellbox is a receptacle where cast metal sorts are thrown after printing. The job of sorting the type from the hellbox and putting it back into the job case was given to the apprentice, known as a printer's devil. Later, when continuous casting or hot metal typesetting machines such as the Linotype and Monotype became popular, the hellbox was used for storing discarded or broken type that were melted down and recast.
Movable type is the system and technology of printing and typography that uses movable components to reproduce the elements of a document usually on the medium of paper.
Recycling is the process of converting waste materials into new materials and objects. This concept often includes the recovery of energy from waste materials. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution and water pollution.
Typesetting is the composition of text for publication, display, or distribution by means of arranging physical type in mechanical systems or glyphs in digital systems representing characters. Stored types are retrieved and ordered according to a language's orthography for visual display. Typesetting requires one or more fonts. One significant effect of typesetting was that authorship of works could be spotted more easily, making it difficult for copiers who have not gained permission.
A miner is a person who extracts ore, coal, chalk, clay, or other minerals from the earth through mining. There are two senses in which the term is used. In its narrowest sense, a miner is someone who works at the rock face; cutting, blasting, or otherwise working and removing the rock. In a broader sense, a "miner" is anyone working within a mine, not just a worker at the rock face.
In the manufacture of metal type used in letterpress printing, a matrix is the mould used to cast a letter, known as a sort. Matrices for printing types were made of copper.
An em is a unit in the field of typography, equal to the currently specified point size. For example, one em in a 16-point typeface is 16 points. Therefore, this unit is the same for all typefaces at a given point size.
In printing and typography, hot metal typesetting is a technology for typesetting text in letterpress printing. This method injects molten type metal into a mold that has the shape of one or more glyphs. The resulting sorts or slugs are later used to press ink onto paper. Normally the typecasting machine would be controlled by a keyboard or by a paper tape.
Scrap consists of recyclable materials, usually metals, left over from product manufacturing and consumption, such as parts of vehicles, building supplies, and surplus materials. Unlike waste, scrap has monetary value, especially recovered metals, and non-metallic materials are also recovered for recycling. Once collected, the materials are sorted into types — typically metal scrap will be crushed, shredded, and sorted using mechanical processes.
A materials recovery facility, materials reclamation facility, materials recycling facility or multi re-use facility is a specialized waste sorting and recycling system that receives, separates and prepares recyclable materials for marketing to end-user manufacturers. Generally, the main recyclable materials include ferrous metal, non-ferrous metal, plastics, paper, glass. Organic food waste is used to anaerobic digestion or composting. Inorganic inert waste is used to make building materials. Non-recyclable high calorific value waste is used to making RDF and SRF.
A printer's devil was a young apprentice in a printing establishment who performed a number of tasks, such as mixing tubs of ink and fetching type. Notable writers including Benjamin Franklin, Walt Whitman, Ambrose Bierce, Bret Harte, and Mark Twain served as printer's devils in their youth along with indentured servants.
In typesetting, a sort or type is a block with a typographic character etched on it, used—when lined up with others—to print text. In movable-type printing, the sort or type is cast from a matrix mold and assembled by hand with other sorts bearing additional characters into lines of type to make up a form, from which a page is printed.
In typesetting, a slug is any of several kinds of piece of lead or other type metal. One kind of slug is a piece of spacing material used to space paragraphs. In the era of commercial typesetting in metal type, they were usually manufactured in strips of 6-point lead. Another kind of slug is a single sort, bearing a single letter or any other symbol. More recently, a slug can be an entire line of Linotype typeset matter, where a single piece of lead has been cast bearing a line of text.
A Ludlow Typograph is a hot metal typesetting system used in letterpress printing. The device casts bars, or slugs of type, out of type metal primarily consisting of lead. These slugs are used for the actual printing, and then are melted down and recycled on the spot. It was used to print large-type material such as newspaper headlines or posters.
Aluminium recycling is the process in which secondary commercial aluminium is created from scrap or other forms of end-of-life or otherwise unusable aluminium. It involves re-melting the metal, which is cheaper and more energy-efficient than the production of virgin aluminium by electrolysis of alumina (Al2O3) refined from raw bauxite by use of the Bayer and Hall–Héroult processes.
Dry contact may mean any of the following in electronics:
Type casting is a technique for casting the individual letters known as sorts used in hot metal typesetting by pouring molten metal into brass moulds called matrices.
Robert Smail's Printing Works is a fully functional Victorian era letterpress printing works in the small Scottish Borders town of Innerleithen, now preserved by The National Trust for Scotland as an Industrial Heritage museum showing visitors the operation of a local printer around 1900 while still carrying out orders for printing and stationery.
Script typefaces are based on the varied and often fluid stroke created by handwriting. They are generally used for display or trade printing, rather than for extended body text in the Latin alphabet. Some Greek alphabet typefaces, especially historically, have been a closer simulation of handwriting.
In typography, the body height or point size refers to the height of the space in which a glyph is defined.
Appliance recycling is the process of dismantling scrapped home appliances to recover their parts or materials for reuse. Recycling appliances for their original or other purposes, involves disassembly, removal of hazardous components and destruction of the equipment to recover materials, generally by shredding, sorting and grading. The rate at which appliances are discarded has increased due in part to obsolescence due to technological advancement, and in part to not being designed to be repairable. The main types of appliances that are recycled are televisions, refrigerators, air conditioners, washing machines, and computers. When appliances are recycled, they can be looked upon as a valuable resources; if disposed of improperly, they can be environmentally harmful and poison ecosystems.
