Johan Petter Johansson
Johan Petter Johansson (December 12, 1853 – August 25, 1943), sometimes known as JP, was a Swedish inventor and industrialist. He invented a modern adjustable spanner (patents in 1891 and 11 May 1892). He obtained over 100 patents in total. He was born in Vårgårda in western Sweden, the oldest of six children in a crofter's family. His first employment was as an assistant operator of a steam engine at a local peat factory. He left Vårgårda at age 19, in 1873, for Motala to work as a navvy. Following military service in 1874, he moved to Eskilstuna where he worked for the Bolinder-Munktell factory, and in 1878 he moved to Västerås where he found employment at a mechanical workshop. Following that, he worked as a blacksmith at a nearby farm. At this time, he had made a decision to leave Sweden for the United States. This never happened; he was instead offered a more esteemed job by his former employer Munktells, and the offer changed his mind. In 1886 he decided to s ...

19th-century Swedish Inventors
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pendulum
A pendulum is a weight suspended from a wikt:pivot, pivot so that it can swing freely. When a pendulum is displaced sideways from its resting, Mechanical equilibrium, equilibrium position, it is subject to a restoring force due to gravity that will accelerate it back toward the equilibrium position. When released, the restoring force acting on the pendulum's mass causes it to oscillate about the equilibrium position, swinging back and forth. The time for one complete cycle, a left swing and a right swing, is called the Frequency, period. The period depends on the length of the pendulum and also to a slight degree on the amplitude, the width of the pendulum's swing. From the first scientific investigations of the pendulum around 1602 by Galileo Galilei, the regular motion of pendulums was used for timekeeping and was the world's most accurate timekeeping technology until the 1930s. The pendulum clock invented by Christiaan Huygens in 1658 became the world's standard timekeeper, u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armature (electrical)
In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. The armature windings conduct AC even on DC machines, due to the commutator action (which periodically reverses current direction) or due to electronic commutation, as in brushless DC motors. The armature can be on either the rotor (rotating part) or the stator (stationary part), depending on the type of electric machine. The armature windings interact with the magnetic field ( magnetic flux) in the air-gap; the magnetic field is generated either by permanent magnets, or electromagnets formed by a conducting coil. The armature must carry current, so it is always a conductor or a conductive coil, oriented normal to both the field and to the direction of motion, torque (rotating machine), or force (linear machine). The armature's role is twofold. The first is to carry current across the field, thus creating shaft torque in a rotating machine or ...

Bahco
Bahco is a Swedish brand within the hand tool industry, which is now part of ''SNA Europe'', part of Snap-on. Its roots go back to the industrial revolution in Sweden in the late eighteen hundreds, starting with innovations such as the pipe wrench and the modern adjustable wrench. Since then, the product range has expanded with a total assortment of products that today includes over 7000 hand tools. History The early years (1880s – 1950s) The story of Bahco began in 1886 when the Swedish inventor Johan Petter Johansson (1853–1943) established his company ''Enköpings Mekaniska Verkstad'' in Enköping, Sweden. Johan Petter, also known as ''JP'', was an inventor and industrialist. He invented the modern plumber wrench (1888) and adjustable wrench (patents in 1891 and 1892). In 1890 the company's sales and marketing rights for its products were acquired by the businessman Berndt August Hjorth (1862–1937), founder of ''BA Hjorth & Co''. In 1916 Johan Petter Johansson ...

Enköping
Enköping is a locality and the seat of Enköping Municipality, Uppsala County, Sweden with 30,000 inhabitants in 2018. Geography Enköping is situated near Lake Mälaren, about 78 km west of Stockholm. A comparably large number of Swedish cities are located in the vicinity of Enköping. The municipal slogan is therefore "Sweden's Closest City". This expression was created in 1965 when it was discovered by a local business that within a radius of 120 kilometers, one finds 38 Swedish cities and a third of Sweden's population. History Near Enköping, there is some of the best preserved rock art from the Bronze Age present in central Sweden. The city of Enköping itself dates its history back to the 13th century but the city itself did not emerge until about 1250. Enköping was then as now situated by the rich farmlands close to lake Mälaren, leading to a wealthy rural population. The city has also always been a major crossroads for commerce, and excellent communi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
