Ring Binder
Ring binders (loose leaf binders, looseleaf binders, or sometimes called files in Britain) are large folders that contain file folders or hole punched papers. These binders come in various sizes and can accommodate an array of paper sizes. These are held in the binder by circular or D-shaped retainers, onto which the contents are threaded. The rings themselves come in a variety of sizes, including , though other sizes are also available. The rings are usually spring-loaded, but can also be secured by lever arch mechanisms or other securing systems. The binders themselves are typically made from plastic with metal rings. Early designs were patented during the early 1890s to the early 1900s. History American Henry Tillinghast Sisson invented the three ring binder, receivinpatent no. 23506on April 5, 1859. German Friedrich Soennecken invented ring binders in 1886 in Bonn. He also registered a patent on November 14, 1886, for his ''Papierlocher für Sammelmappen'' ("paper hole ...

Lever Arch File
A lever is a simple machine consisting of a beam or rigid rod pivoted at a fixed hinge, or ''fulcrum''. A lever is a rigid body capable of rotating on a point on itself. On the basis of the locations of fulcrum, load and effort, the lever is divided into three types. Also, leverage is mechanical advantage gained in a system. It is one of the six simple machines identified by Renaissance scientists. A lever amplifies an input force to provide a greater output force, which is said to provide leverage. The ratio of the output force to the input force is the mechanical advantage of the lever. As such, the lever is a mechanical advantage device, trading off force against movement. Etymology The word "lever" entered English around 1300 from Old French, in which the word was ''levier''. This sprang from the stem of the verb ''lever'', meaning "to raise". The verb, in turn, goes back to the Latin ''levare'', itself from the adjective ''levis'', meaning "light" (as in "not heavy"). T ...

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...

Sheet Protector
A punched pocket (UK English), plastic wallet (UK English), poly pocket (UK English), slippery fish (Sussex, England), sheet protector (US English), plastic sleeves (AU English), or sometimes perforated document bag, is a flat, slit plastic bag with a perforated edge used to hold paper documents. Physical characteristics Punched pockets are usually transparent or semi-transparent, to allow viewing of the contents of a document without removing it. Color pockets are also available. They protect paper documents from tears, water, food, stains, and fingerprints, and partially prevent such documents from being crumpled. Punched pockets have several holes in the left edge, which allow them to be bound into a file, or a three-ring binder. The holes in the punched pockets dispose of the difficulty of making holes in a paper document. The most commonly used material for punched pockets is polypropylene. However, there are some punched pockets made of polyethylene, cellophane, or other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polypropylene
Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. Its properties are similar to polyethylene, but it is slightly harder and more heat-resistant. It is a white, mechanically rugged material and has a high chemical resistance. Bio-PP is the bio-based counterpart of polypropylene (PP). Polypropylene is the second-most widely produced commodity plastic (after polyethylene). In 2019, the global market for polypropylene was worth $126.03 billion. Revenues are expected to exceed US$145 billion by 2019. The sales of this material are forecast to grow at a rate of 5.8% per year until 2021. History Phillips Petroleum chemists J. Paul Hogan and Robert Banks first demonstrated the polymerization of propylene in 1951. The stereoselective polymerizat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slipcase
A slipcase is a five-sided box, usually made of high-quality cardboard, into which binders, books or book sets are ''slipped'' for protection, leaving the spine exposed. Special editions of books are often slipcased for a stylish appearance when placed on a bookshelf. A few publishers, such as the Folio Society, publish all their books in slipcases. Protective slipcases may be issued for cassettes, compact discs or DVD The DVD (common abbreviation for Digital Video Disc or Digital Versatile Disc) is a digital optical disc data storage format.

Compact Disc
The compact disc (CD) is a digital optical disc data storage format that was co-developed by Philips and Sony to store and play digital audio recordings. In August 1982, the first compact disc was manufactured. It was then released in October 1982 in Japan and branded as '' Digital Audio Compact Disc''. The format was later adapted (as CD-ROM) for general-purpose data storage. Several other formats were further derived, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video CD (VCD), Super Video CD (SVCD), Photo CD, Picture CD, Compact Disc-Interactive ( CD-i) and Enhanced Music CD. Standard CDs have a diameter of and are designed to hold up to 74 minutes of uncompressed stereo digital audio or about 650 MiB of data. Capacity is routinely extended to 80 minutes and 700 MiB by arranging data more closely on the same sized disc. The Mini CD has various diameters ranging from ; they are sometimes used for CD singles, storin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business Cards
Business cards are cards bearing business information about a company or individual. They are shared during formal introductions as a convenience and a memory aid. A business card typically includes the giver's name, company or business affiliation (usually with a logo) and contact information such as street addresses, telephone number(s), fax number, e-mail addresses and website. Before the advent of electronic communication business cards might also include telex details. Now they may include social media addresses such as Facebook, LinkedIn and Twitter. Traditionally, many cards were simple black text on white stock, and the distinctive look and feel of cards printed from an engraved plate was a desirable sign of professionalism. In the late 20th century, technological advances drove changes in style, and today a professional business card will often include one or more aspects of striking visual design. Prior to the COVID-19 pandemic, approximately 7 billion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Book Cover
A book cover is any protective covering used to bind together the pages of a book. Beyond the familiar distinction between hardcovers and paperbacks, there are further alternatives and additions, such as dust jackets, ring-binding, and older forms such as the nineteenth-century "paper-boards" and the traditional types of hand-binding. The term "Bookcover" is often used for a book cover image in library management software. This article is concerned with modern mechanically produced covers. History Before the early nineteenth century, books were hand-bound, in the case of luxury medieval manuscripts in treasure bindings using materials such as gold, silver and jewels. For hundreds of years, book bindings had functioned as a protective device for the expensively printed or hand-made pages, and as a decorative tribute to their cultural authority. In the 1820s great changes began to occur in how a book might be covered, with the gradual introduction of techniques for mechanic ...

Hardback Book
A hardcover, hard cover, or hardback (also known as hardbound, and sometimes as case-bound) book is one bound with rigid protective covers (typically of binder's board or heavy paperboard covered with buckram or other cloth, heavy paper, or occasionally leather). It has a flexible, sewn spine which allows the book to lie flat on a surface when opened. Modern hardcovers may have the pages glued onto the spine in much the same way as paperbacks. Following the ISBN sequence numbers, books of this type may be identified by the abbreviation Hbk. Hardcover books are often printed on acid-free paper, and they are much more durable than paperbacks, which have flexible, easily damaged paper covers. Hardcover books are marginally more costly to manufacture. Hardcovers are frequently protected by artistic dust jackets, but a "jacketless" alternative has increased in popularity: these "paper-over-board" or "jacketless" hardcover bindings forgo the dust jacket in favor of printing the cover ...
