Mounted Corkscrew
A mounted or bar corkscrew is a device screwed or clamped to a wall or counter top, used to draw corks from beer, wine or other bottles. History Corks have been used to seal jars and bottles for over 400 years. (Modern, machine made bottles with threaded tops for screw caps date from the 1920s.) Early glass bottles were cumbersome (and possibly dangerous, being hand-blown) to hold, and the simple “T” corkscrew required strength to use. The first mounted corkscrews, made some time in the mid 1800s, were very simple, consisting of a frame incorporating a bracket that held the bottle down and a metal hook that pulled almost any “T” handled corkscrew up. The helix or worm was turned into the cork, then the bottle was held with the protruding corkscrew in the frame, with the lever hooked onto it. Pulling the lever extracted the cork. The mechanical advantage incorporated into these frames consisted of various types of rack and pinion, gear or lever mechanisms. Turning the wo ...

Utility (patent)
In United States patent law, utility is a patentability requirement. As provided by , an invention is "useful" if it provides some identifiable benefit and is capable of use and "useless" otherwise. The majority of inventions are usually not challenged as lacking utility, but the doctrine prevents the patenting of fantastic or hypothetical devices such as perpetual motion machines. The patent examiners guidelines require that a patent application expresses a specific, credible, and substantial utility. Rejection by an examiner usually requires documentary evidence establishing a ''prima facie'' showing that there is no specific, substantial, and credible utility. European patent law does not consider utility as a patentability criterion. Instead, it requires that to be patentable an invention must have industrial applicability. Utility criteria In considering the requirement of utility for patents, there are three main factors to review: operability of the invention, a benefic ...

Point Of Sale
The point of sale (POS) or point of purchase (POP) is the time and place at which a retail transaction is completed. At the point of sale, the merchant calculates the amount owed by the customer, indicates that amount, may prepare an invoice for the customer (which may be a cash register printout), and indicates the options for the customer to make payment. It is also the point at which a customer makes a payment to the merchant in exchange for goods or after provision of a service. After receiving payment, the merchant may issue a receipt for the transaction, which is usually printed but can also be dispensed with or sent electronically. To calculate the amount owed by a customer, the merchant may use various devices such as weighing scales, barcode scanners, and cash registers (or the more advanced "POS cash registers", which are sometimes also called "POS systems"). To make a payment, payment terminals, touch screens, and other hardware and software options are available. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landers, Frary & Clark
Landers, Frary & Clark was a housewares company based in New Britain, Connecticut. The firm traced its origins to 1842, when George M. Landers and Josiah Dewey entered into a partnership named Dewey and Landers, which manufactured various metal products. Eventually, the company was reorganized as Landers, Frary & Clark in 1862. The firm produced a variety of household products and appliances, including many electric appliances. Some of Landers, Frary & Clark's most successful products included the Universal Bread Maker, the Universal Food Chopper, and the Coffee Percolator. In 1965, the majority of the Landers, Frary & Clark was taken over by the J.B. Williams Company of New York, the food chopper division was acquired by the Union Manufacturing Company, and the electrical appliance operations was purchased by General Electric.

Freeport, Illinois
Freeport is the county seat and largest city of Stephenson County, Illinois, United States. The population was 23,973 at the 2020 census, and the mayor of Freeport is Jodi Miller, elected in 2017. Freeport is known for hosting the second Lincoln-Douglas debate of 1858, and as "Pretzel City, USA", due to a popular local German bakery known for its pretzels in the 1850s. Freeport High School's mascot is the Pretzel to honor its heritage. History The community was originally called Winneshiek. When it was incorporated, the new municipality took its name from the generosity of Tutty Baker, who was credited with running a "free port" on the Pecatonica River. The name "Winneshiek" was later adopted, and is preserved to this day, by the Freeport Community Theatre Group. In 1837, Stephenson County was formed and Freeport became its seat of government in 1838. Linked by a stagecoach with Chicago, the community grew rapidly. In 1840, a frame courthouse was erected and the first schoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brass
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] |
Nickel
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cast Iron
Cast iron is a class of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its color when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite "nodules" which stop the crack from further progressing. Carbon (C), ranging from 1.8 to 4 wt%, and silicon (Si), 1–3 wt%, are the main alloying elements of cast iron. Iron alloys with lower carbon content are known as steel. Cast iron tends to be brittle, except for malleable cast irons. With its relatively low melting point, good fluidity, castability, excellent machinability, resistance to deformation and wear resistance, cast irons have become an engineering material with a wide range of applications and are ...

Design Patent
In the United States, a design patent is a form of legal protection granted to the ornamental design of an article of manufacture. Design patents are a type of industrial design right. Ornamental designs of jewelry, furniture, beverage containers (Fig. 1) and computer icons are examples of objects that are covered by design patents. A similar intellectual property right, a registered design, can be obtained in other countries. In Kenya, Japan, South Korea and Hungary, industrial designs are registered after performing an official novelty search. In the countries of the European Community, one needs to only pay an official fee and meet other formal requirements for registration (e.g. Community design at EUIPO, Germany, France, Spain). For the member states of WIPO, cover is afforded by registration at WIPO and examination by the designated member states in accordance with the Geneva Act of the Hague Agreement.
