Generic trademark in the context of "Ouija"

A photocopier (also called copier or copy machine, and formerly Xerox machine, the generic trademark) is a machine that makes copies of documents and other visual images onto paper or plastic film quickly and cheaply. Most modern photocopiers use a technology called xerography, a dry process that uses electrostatic charges on a light-sensitive photoreceptor to first attract and then transfer toner particles (a powder) onto paper in the form of an image. The toner is then fused onto the paper using heat, pressure, or a combination of both. Copiers can also use other technologies, such as inkjet, but xerography is standard for office copying.

Commercial xerographic office photocopying gradually replaced copies made by verifax, photostat, carbon paper, mimeograph machines, and other duplicating machines.

A cultipacker is a piece of agricultural equipment that crushes dirt clods, removes air pockets, and presses down small stones, forming a smooth, firm seedbed. Where seed has been broadcast, the roller gently firms the soil around the seeds, ensuring shallow seed placement and good seed-to-soil contact.

The term cultipacker is almost exclusively applied to ridged rollers, while the terms field roller or land roller may refer to either a smooth or a ridged roller. Some farmers treat the terms as mutually exclusive, but many others treat the ridged tools as a class of field rollers. For example, C.H. Wendel's Encyclopedia of American Farm Implements and Antiques covers the whole category as land rollers. The term cultipacker appeared in English around 1914 and probably originated as a brand name of the C.G. Dunham Company of Berea, Ohio, which advertised "Culti-Packer" models starting around that time. That company did not have the ridged-roller subcategory to itself by any stretch, as Wendel's book demonstrates, but for whatever reason, its name for its version stuck well in many minds. By the 1920s and ever since, it has been widely used in a genericized sense, at least in some regions of the U.S. if not nationwide. In Britain, an equivalent tool is usually called a Cambridge roller or Cambridge roll; D.J. Smith's Discovering Horse-drawn Farm Machinery says, "The Cambridge roll, named after its makers, was a ring roller made up of numerous equally spaced rings or ridges."

Kerosene, or paraffin, is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from the Greek κηρός (kērós) meaning "wax"; it was registered as a trademark by Nova Scotia geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage.

Kerosene is widely used to power jet engines of aircraft (jet fuel), as well as some rocket engines in a highly refined form called RP-1. It is also commonly used as a cooking and lighting fuel, and for fire toys such as poi. In parts of Asia, kerosene is sometimes used as fuel for small outboard motors or even motorcycles. World total kerosene consumption for all purposes is equivalent to about 5,500,000 barrels per day as of July 2023.

Gouda cheese (/ˈɡaʊdə/ , US also /ˈɡuːdə/ ; Dutch: [ˈɣʌudaː] ; Dutch: Goudse kaas, "cheese from Gouda") is a creamy, yellow cow's milk cheese originating from the Netherlands. It is one of the most popular and produced cheeses worldwide. The name is used today as a general term for numerous similar cheeses produced in the traditional Dutch manner.

Adobe Photoshop is a raster graphics editor developed and published by Adobe for Windows and macOS. It was created in 1987 by Thomas and John Knoll. It is the most used tool for professional digital art, especially in raster graphics editing, and its name has become genericised as a verb (e.g., to "photoshop" an image, "photoshopping", and "photoshop contest") although Adobe disapproves of such use.

Photoshop can edit and compose raster images in multiple layers and supports masks, alpha compositing and several color models. Photoshop uses its own PSD and PSB file formats to support these features. In addition to raster graphics, Photoshop has limited abilities to edit or render text and vector graphics (especially through clipping path for the latter), as well as 3D graphics and video. Its feature set can be expanded by plug-ins; programs developed and distributed independently of Photoshop that run inside it and offer new or enhanced features.

Detonating cord (also called detonation cord, detcord, detacord, blasting rope, or primer cord) is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite). With the PETN exploding at a rate of approximately 6,400 m/s (21,000 ft/s), any common length of detonation cord appears to explode instantaneously. It is a high-speed fuse which explodes, rather than burns, and is suitable for detonating high explosives. The detonation velocity is sufficient to use it for synchronizing multiple charges to detonate almost simultaneously even if the charges are placed at different distances from the point of initiation. It is used to reliably and inexpensively chain together multiple explosive charges. Typical uses include mining, drilling, demolitions, and warfare.

"Cordtex" and "Primacord" are two of many trademarks which have slipped into use as a generic term for this material.

The Photostat machine, or Photostat, was an early projection photocopier created in the decade of the 1900s by the Commercial Camera Company, which became the Photostat Corporation. The "Photostat" name, which was originally a trademark of the company, became genericized, and was often used to refer to similar machines produced by the RetinalGraph Company or to any copy made by any such machine.
