Louis Heinrici
Louis Heinrici (1847 - c.1930) was a German industrialist and manufacturer. Personal life Louis Heinrici was born on 30 July 1847 in Torgau and died c.1930 in Zwickau. He married Marie Elisabeth (Born Deustler) with whom he had three sons: Joseph Hans Louis Heinrici, Ernst Hermann Heinrici and Rudolf Heinrici. Business In 1876, Louis Heinrici began to manufacture hot air engines, and other small engines, initially in rented rooms. His first factory building was built in 1884 in Zwickau (Saxony). The factory started with two workers, a lathe and a forge. The official company name was: Louis Heinrici, mechanical workshops for precision work, Zwickau in Saxony. The hot-air engines produced by Heinrici, as a mass-produced product, were widely used in the commercial and private sectors because they served as inexpensive and reliable sources of power. In 1914, the factory had areas for metalworking, plumbing, a paint shop, another building for the turning shop and a laboratory and tr ...

Torgau
Torgau () is a town on the banks of the Elbe in northwestern Saxony, Germany. It is the capital of the district Nordsachsen. Outside Germany, the town is best known as where on 25 April 1945, the United States and Soviet Armies forces first met near the end of the World War II. History The settlement goes back to a Slavonic settlement named Turguo in the shire of Neletici. There was presumably a wooden Slavonic castle located on the site of the present-day Hartenfels castle. In the 10th century it fell under the rule of the Holy Roman Emperors, and a stone castle was built, around which the settlement congregated. A market is attested in 1119. The town was located on the important trade-road, the via regia Lusatiae inferioris, between Leipzig and Frankfurt an der Oder that crossed the river Elbe at a ford east of Torgau. Torgau belonged to the duchy of Saxe-Wittenberg, which in 1356 was raised to be the Electorate of Saxony. After the last Ascanian duke died without is ...

Zwickau
Zwickau (; is, with around 87,500 inhabitants (2020), the fourth-largest city of Saxony after Leipzig, Dresden and Chemnitz and it is the seat of the Zwickau District. The West Saxon city is situated in the valley of the Zwickau Mulde (German: ''Zwickauer Mulde''; progression: ), and lies in a string of cities sitting in the densely populated foreland of the Elster and Ore Mountains stretching from Plauen in the southwest via Zwickau, Chemnitz and Freiberg to Dresden in the northeast. From 1834 until 1952, Zwickau was the seat of the government of the south-western region of Saxony. The name of the city is of Sorbian origin and may refer to Svarog, the Slavic god of fire and of the sun. Zwickau is the seat of the West Saxon University of Zwickau (German: ''Westsächsische Hochschule Zwickau'') with campuses in Zwickau, Markneukirchen, Reichenbach im Vogtland and Schneeberg (Erzgebirge). The city is the birthplace of composer Robert Schumann. As cradle of Audi's forerunner ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Air Engine
A hot air engine (historically called an air engine or caloric engine) is any heat engine that uses the expansion and contraction of air under the influence of a temperature change to convert thermal energy into mechanical work. These engines may be based on a number of thermodynamic cycles encompassing both open cycle devices such as those of Sir George Cayley and John Ericsson and the closed cycle engine of Robert Stirling. Hot air engines are distinct from the better known internal combustion based engine and steam engine. In a typical implementation, air is repeatedly heated and cooled in a cylinder and the resulting expansion and contraction are used to move a piston and produce useful mechanical work. Definition The term "hot air engine" specifically excludes any engine performing a thermodynamic cycle in which the working fluid undergoes a phase transition, such as the Rankine cycle. Also excluded are conventional internal combustion engines, in which heat is added to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dynamo
file:DynamoElectricMachinesEndViewPartlySection USP284110.png, "Dynamo Electric Machine" (end view, partly section, ) A dynamo is an electrical generator that creates direct current using a commutator (electric), commutator. Dynamos were the first electrical generators capable of delivering power for industry, and the foundation upon which many other later Electric power conversion, electric-power conversion devices were based, including the electric motor, the Alternating current, alternating-current alternator, and the rotary converter. Today, the simpler alternator dominates large scale Electricity generation, power generation, for efficiency, reliability and cost reasons. A dynamo has the disadvantages of a commutator (electric), mechanical commutator. Also, converting alternating to direct current using rectifiers (such as vacuum tubes or more recently via Solid state (electronics), solid state technology) is effective and usually economical.

Engineers From Saxony
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professional pr ...

1930 Deaths
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * January 1 – Year of the Five Emperors: The Roman Senate chooses Publius Helvius Pertinax, against his will, to succeed the late Commodus as Emperor. Pertinax is forced to reorganize the handling of finances, which were wrecked under Commodus, to reestablish discipline in the Roman army, and to suspend the food programs established by Trajan, provoking the ire of the Praetorian Guard. * March 28 – Pertinax is assassinated by members of the Praetorian Guard, who storm the imperial palace.
