Bertha Benz
Bertha Benz (; ; 3 May 1849 – 5 May 1944) was a German automotive pioneer. She was the business partner, investor and wife of automobile inventor Carl Benz. On 5 August 1888, she was the first person to drive an Internal combustion engine, internal-combustion-engined automobile over a long distance, field testing the Benz Patent-Motorwagen, inventing brake lining and solving several practical issues during the journey of 105 km (65 miles). In doing so, she brought the Patent-Motorwagen worldwide attention and got their company its first sales. Bertha Benz was not allowed to study in the Grand Duchy of Baden, and her financial and practical engineering contributions have long been overlooked until the 21st century. Early life and education Cäcilie Bertha Ringer was born on 3 May 1849 to a wealthy carpenter family in Pforzheim. She was the third of nine children. Her father, Karl Friedrich Ringer, a master builder and carpenter, and her 20 year younger mother, Auguste Fri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Carl Benz
Carl (or Karl) Friedrich Benz (; born Karl Friedrich Michael Vaillant; 25 November 1844 – 4 April 1929) was a German engine designer and automotive engineer. His Benz Patent-Motorwagen from 1885 is considered the first practical modern automobile and first car put into series production. He received a patent for the motorcar in 1886, the same year he first publicly drove the Benz Patent-Motorwagen. His company Benz & Cie., based in Mannheim, was the world's first automobile plant and largest of its day. In 1926, it merged with Daimler Motoren Gesellschaft to form Daimler-Benz, which produces the Mercedes-Benz among other brands. Benz is widely regarded as "the father of the car", as well as the "father of the automobile industry". Early life Carl Benz was born Karl Friedrich Michael Vaillant on 25 November 1844 in Mühlburg, now a borough of Karlsruhe, Baden-Württemberg, which is part of modern Germany. His parents were Josephine Vaillant and a locomotive driver, Johann Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Gottlieb Daimler
Gottlieb Wilhelm Daimler (; 17 March 1834 – 6 March 1900) was a German engineer, industrial designer and industrialist. He was a pioneer of internal-combustion engines and automobile development. He invented the high-speed liquid petroleum-fueled engine. Daimler and his lifelong business partner Wilhelm Maybach were two inventors whose goal was to create small, high-speed engines to be mounted in any kind of locomotion device. In 1883 they designed a horizontal cylinder layout compressed charge liquid petroleum engine that fulfilled Daimler's desire for a high speed engine which could be throttled, making it useful in transportation applications. This engine was called Daimler's Dream. In 1885 they designed a vertical cylinder version of this engine which they subsequently fitted to a two-wheeler, the first internal combustion motorcycle which was named the Reitwagen, Petroleum Reitwagen (Riding Car) and, in the next year, to a Coach (carriage), coach, and a boat. Daimler call ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Gear
A gear or gearwheel is a rotating machine part typically used to transmit rotational motion and/or torque by means of a series of teeth that engage with compatible teeth of another gear or other part. The teeth can be integral saliences or cavities machined on the part, or separate pegs inserted into it. In the latter case, the gear is usually called a cogwheel. A cog may be one of those pegsDefinition of "cog" in the ''Oxford Learner's Dictionary'' online. Accessed on 2024-07-29.Definition of "cog" in the ''Merriam-Webster Dictionary'' online.

Hopper Cooling
Hopper cooling is a simple form of water cooling used for small stationary engines. The defining feature of hopper cooling, amongst other water-cooled engines, is that there is no radiator (engine cooling), radiator. Cooling water is heated by the engine and evaporation, evaporates from the surface of the hopper as steam. Operation Internal combustion engines are rather inefficient and require Internal combustion engine cooling, cooling to dispose of the waste heat they generate when running. Water-cooled engines remove this heat from around the cylinder head by surrounding it with a water jacket. In most familiar engines today, this water is circulated from the hot parts of the engine to a radiator, where it gives up its heat to the air. In early and low powered engines with hopper cooling there is little circulation. Water is instead slowly boiled off, with the heat of vaporisation needed to boil the water coming from the engine heat. The loss of heat with this departing wat ...

Blacksmith
A blacksmith is a metalsmith who creates objects primarily from wrought iron or steel, but sometimes from #Other metals, other metals, by forging the metal, using tools to hammer, bend, and cut (cf. tinsmith). Blacksmiths produce objects such as gates, grilles, railings, light fixtures, furniture, sculpture, tools, agricultural implements, decorative and religious items, cooking utensils, and weapons. There was a historical distinction between the heavy work of the blacksmith and the more delicate operations of a whitesmith, who usually worked in Goldsmith, gold, Silversmith, silver, pewter, or the finishing steps of fine steel. The place where a blacksmith works is variously called a smithy, a forge, or a blacksmith's shop. While there are many professions who work with metal, such as farriers, wheelwrights, and Armourer, armorers, in former times the blacksmith had a general knowledge of how to make and repair many things, from the most complex of weapons and armor to simple ...

Garter
A garter is an article of clothing comprising a narrow band of fabric fastened about the leg to keep up stockings. In the eighteenth to twentieth centuries, they were tied just below the knee, where the leg is most slender, to keep the stocking from slipping. The advent of elastic has made them less necessary from this functional standpoint, although they are still often worn for fashion. Garters have been widely worn by men and women, depending on fashion trends. Garters in fashion In Elizabethan fashions, men wore garters with their hose, and colourful garters were an object of display. In Shakespeare's ''Twelfth Night'', "cross braced" garters (a long garter tied above and below the knee and crossed between), as worn by the character Malvolio, are an object of some derision. In male fashion for much of the 20th century a type of garter for holding up socks was used as a part of male dress; it is considered somewhat archaic now.

Pharmacy
Pharmacy is the science and practice of discovering, producing, preparing, dispensing, reviewing and monitoring medications, aiming to ensure the safe, effective, and affordable use of medication, medicines. It is a miscellaneous science as it links health sciences with pharmaceutical sciences and natural sciences. The professional practice is becoming more clinically oriented as most of the drugs are now manufactured by pharmaceutical industries. Based on the setting, pharmacy practice is either classified as community or institutional pharmacy. Providing direct patient care in the community of institutional pharmacies is considered clinical pharmacy. The scope of pharmacy practice includes more traditional roles such as compounding and dispensing of medications. It also includes more modern services related to health care including clinical services, reviewing medications for safety and efficacy, and providing drug information with patient counselling.

Apothecary
''Apothecary'' () is an Early Modern English, archaic English term for a medicine, medical professional who formulates and dispenses ''materia medica'' (medicine) to physicians, surgeons and patients. The modern terms ''pharmacist'' and, in British English, ''chemist'' have taken over this role. In some languages and regions, terms similar to "apothecary" have survived and denote modern pharmacies or pharmacists. Apothecaries' investigation of Herbal medicine, herbal and chemical ingredients was a precursor to the modern sciences of chemistry and pharmacology. In addition to dispensing herbs and medicine, apothecaries offered general medical advice and a range of services that are now performed by other specialist practitioners, such as surgeons and Obstetrics and gynaecology, obstetricians. Apothecary shops sold ingredients and the medicines they prepared wholesale to other medical practitioners, as well as dispensing them to patients. In 17th-century England, they also contro ...

Ligroin
Ligroin is the petroleum fraction consisting mostly of C7 and C8 hydrocarbons and boiling in the range 90‒140 °C (194–284 °F). The fraction is also called heavy naphtha. Ligroin is used as a laboratory solvent. Products under the name ligroin can have boiling ranges as low as 60‒80 °C and may be called light naphtha. The name ''ligroin'' (or ''ligroine'' or ''ligroïne'') appeared as early as 1866.The name "ligroin" was coined in the United States: * From p. 349: ''"Ligroine; der in Amerika erfundene Name für einen der flüchtigeren Teile des rohen Petroleums, … "'' (Ligroin: the name that was coined in America for one of the more volatile parts of crude petroleum, … ) Early use in English: * From p. 389: "Dr. Van der Weyde then exhibited some samples of the products of distillation of tar, and a safety-lamp for burning the lighter hydro-carbons, which is mainly a reproduction of the "Ligroine" lamp invented and put into the market first by C.

Carburetor
A carburetor (also spelled carburettor or carburetter) is a device used by a gasoline internal combustion engine to control and mix air and fuel entering the engine. The primary method of adding fuel to the intake air is through the Venturi effect or Bernoulli's principle or with a Pitot tube in the main metering circuit, though various other components are also used to provide extra fuel or air in specific circumstances. Since the 1990s, carburetors have been largely replaced by fuel injection for cars and trucks, but carburetors are still used by some small engines (e.g. lawnmowers, generators, and concrete mixers) and motorcycles. In addition, they are still widely used on piston-engine–driven aircraft. Diesel engines have always used fuel injection instead of carburetors, as the compression-based combustion of diesel requires the greater precision and pressure of fuel injection. Etymology The term ''carburetor'' is derived from the verb ''carburet'', which means "to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
