Bertha Benz
Bertha Benz (; ; 3 May 1849 – 5 May 1944) was a German automotive pioneer and inventor. She was the business partner and wife of automobile inventor Carl Benz. On 5 August 1888, she was the first person to drive an 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 the company its first sales. Early life and marriage Cäcilie Bertha Ringer was born on 3 May 1849 to a wealthy family in Pforzheim in the Grand Duchy of Baden. Two years before her marriage to Carl Benz, she used part of her dowry to invest in his failing iron construction company. As an unmarried woman, she was able to do so; after she married Benz, according to German law, Bertha lost her legal power to act as an investor. On 20 July 1872, Bertha Ringer married Carl Benz.

Carl Benz
Carl Friedrich Benz (; 25 November 1844 – 4 April 1929), sometimes also Karl Friedrich Benz, was a German engine designer and automotive engineer. His Benz Patent Motorcar 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. 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" and "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 Georg Benz, whom she married a few months later. According to German law, the child acquired ...

Carburetor
A carburetor (also spelled carburettor) is a device used by an 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 tube in the main metering circuit, however 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, however carburetors are still used by some small engines (e.g. lawnmowers, generators and concrete mixers) and motorcycles. Diesel engines have always used fuel injection instead of carburetors. Etymology The name "carburetor" is derived from the verb ''carburet'', which means "to combine with carbon," or in particular, "to enrich a gas by combining it with carbon or hydrocarbons." Thus a carburetor mixes intake air with hydrocarbon-based fuel, such as petrol or autogas (LPG). The name is spelled "carburetor" in American English ...

Bertha Benz Pit Elsasser Wiesloch
Bertha is a female Germanic name, from Old High German ''berhta'' meaning "bright one". It was usually a short form of Anglo Saxon names ''Beorhtgifu'' meaning "bright gift" or ''Beorhtwynn'' meaning "bright joy". The name occurs as a theonym, surviving as Berchta, a figure in Alpine folklore connected to the Wild Hunt, probably an epithet of ''*Frijjō'' in origin. ''Bertha'' appears as a Frankish given name from as early as the 6th century. The monothematic ''Bertha'' as a given name may, however, not originate with the theonym but rather as a short form of dithematic given names including the "bright" element. This is notably the case with the mother of Charlemagne, Bertrada (properly ''berht-rada'' "bright counsel") called "Bertha Broadfoot." Carolingian uses of the name ''Bertha'', as in the case of Bertha, daughter of Charlemagne and Bertha, daughter of Lothair II, are in this tradition. In modern times, the name is associated with an unusually large example of a class ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Test Drive
A test drive is the driving of a motor vehicle to assess its drivability or roadworthiness, and general operating state. A person who tests vehicles for a living, either for an automobile company, automotive media for review purposes, or a motorsports team, is called a test driver. The first test drives of a new production vehicle are made by mainstream automobile magazines and other third parties (not customers) for initial evaluation. Once vehicles are for sale, test drives are also usually allowed by vehicle traders (dealerships) or manufacturers to enable prospective customers to determine the suitability of the vehicle to their driving style. Test drives can also be taken before vehicle repairs to assist in diagnosis or after repair works to ensure that the vehicle has been fully restored. In a broader sense, "test drive" can be used to refer to the testing of anything, such as a computer program, an idea or process, a pair of shoes, etc. See also * Proving ground * Test ...

Automotive Industry
The automotive industry comprises a wide range of company, companies and organizations involved in the design, Business development, development, manufacturing, marketing, and selling of motor vehicles. It is one of the world's largest industry (economics), industries by revenue (from 16 % such as in France up to 40 % to countries like Slovakia). It is also the industry with the highest spending on research & development per firm. The word ''automotive'' comes from the Greek language, Greek ''autos'' (self), and Latin ''motivus'' (of motion), referring to any form of self-powered vehicle. This term, as proposed by Elmer Ambrose Sperry, Elmer Sperry (1860-1930), first came into use with reference to automobiles in 1898. History The automotive industry began in the 1860s with hundreds of manufacturers that pioneered the Brass Era car, horseless carriage. For many decades, the United States led the world in total automobile production. In 1929, before the Great Depression, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gear
A gear is a rotating circular machine part having cut teeth or, in the case of a cogwheel or gearwheel, inserted teeth (called ''cogs''), which mesh with another (compatible) toothed part to transmit (convert) torque and speed. The basic principle behind the operation of gears is analogous to the basic principle of levers. A gear may also be known informally as a cog. Geared devices can change the speed, torque, and direction of a power source. Gears of different sizes produce a change in torque, creating a mechanical advantage, through their ''gear ratio'', and thus may be considered a simple machine. The rotational speeds, and the torques, of two meshing gears differ in proportion to their diameters. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a '' transmission''. The gears in a transmission are analogous to the wheels in a crossed, belt pulley system. An advantage of gears is tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Cooling water is heated by the engine and evaporates from the surface of the hopper as steam. Operation Internal combustion engines are rather inefficient and require 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 water vapour is enough to cool the engine. As the heat of vaporisation (energy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 an historical distinction between the heavy work of the blacksmith and the more delicate operation 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 called variously a smithy, a forge or a blacksmith's shop. While there are many people 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 things ...

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. Use in wedding traditions There is a Weste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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. Pharmacists, therefore, are experts on drug therapy and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
