Museum of Clockmaking

Uhrenindustriemuseum
They have all the machinery in-house to produce all components (except for the mainspring) to manufacture a simple alarm clock movement. Staffing permitting, the full museum visit includes a demonstration of the lathes, milling machines and punch presses, as well as the assembly and packaging process. In addition, there is a comprehensive display of locally mass-produced clocks from most of the former clock factories of Schwenningen. The museum also puts on temporary exhibitions. *http://www.uhrenindustriemuseum.de Uhrenindustriemusem Villingen-Schwenningen (Website available only in German) Horology. German Clock Museum.

Metronome

metronomicM.M.metronome mark
Mechanical metronomes don't need a battery, but run from a spring-wound clockwork escapement. Most modern metronomes are electronic and use a quartz crystal to maintain accuracy, comparable to those used in wristwatches. The simplest electronic metronomes have a dial or buttons to control the tempo; some also produce tuning notes, usually around the range of A440 (440 hertz). Sophisticated metronomes can produce two or more distinct sounds. Tones can differ in pitch, volume, and/or timbre to demarcate downbeats from other beats, as well as compound and complex time signatures. Many electronic musical keyboards have built-in metronome functions.

Time discipline

Intellectual history of time
Minute hands did not come into widespread use until the pendulum enabled a large leap in the accuracy of clocks; for watches, a similar leap in accuracy was not made possible before the invention of the balance spring. Before these improvements, the equation of time, the difference between apparent and mean solar time, was not even noticed. During the 17th and 18th centuries, private ownership of clocks and watches became more common, as their improved manufacture made them available for purchase by at least the bourgeoisie of the cities. Their proliferation had many social and even religious consequences for those who could afford and use them.

Patek Philippe SA

Patek PhilippePatek Philippe & Co.Patek Phillipe
In 2006, introduced the silicon-based Spiromax balance spring. In 2008, introduced the Pulsomax silicon-based escapement. In 2011, introduced the Oscillomax ensemble, combining the Spiromax balance spring, the Pulsomax escapement, and the GyromaxSi balance. In 2014, created the Grandmaster Chime Ref. 5175, one of the world's most complicated wristwatches (20 complications). On November 28, 2012, the Patek Philippe Star Calibre 2000 Ref. 990/1 was sold at Christie's in Hong Kong for a final price of 3.28 million US dollars (HKD 25,300,000), becoming the most expensive timepiece ever auctioned in Asia.

During his fight with the mainspring Donald responds to the taunting spring by saying "Says who!?" (which is made clear by the spring replying, "Says I!") and then threatens the mainspring, calling it a "snake in the grass". However, due to Donald's unintelligible "duck voice", some believed that he was instead saying "fuck you" to the mainspring and calling it a "son of a bitch". Disney would not have been allowed to release the cartoon in theaters if the foul words were actually used; the Motion Picture Production Code of 1930 was heavily enforced then and would have prevented Disney from doing so.

IS-7

The IS-7 has a total of seven road wheels attached to road wheel arms on torsion bars, limited by volute spring bump stops, and hydraulic shock absorbers. The rear allowed for external fuel tanks to be carried. * British Conqueror heavy tank designed after World War II * Kubinka Tank Museum, Russia. * Part 1 and Part 2 of "Inside the Chieftain's Hatch: IS-7" video reviews IS tank family.

Mido (watch)

Mido
In that same year Mido launched watches with unbreakable mainsprings. This was also the very first time that any watch manufacturer utilized this type of spring within the marketplace. During this time period, Mido used a Robot as its ambassador as a symbol of progress and robustness. A comic strip from this era featured the Mido Robot and its adventures. In 1945, Mido became the first manufacturer to introduce a central-read chronograph wherein the stopwatch function had all its hands arranged at the center. In 1954 the firm launched the world's most efficient winding mechanism. Mido released its Commander model in 1959, which utilized a one-piece case design.

Volute (disambiguation)

Volute spring, a compression spring in the form of a cone. Volute, a spiral or scroll form in the arabesque form of artistic decoration. Volute, a handrail for a bullnose step that is shaped like a spiral; See Stairs. Volute krater, a type of Greek urn. Volute, a scroll shaped carving at the tuning head of stringed musical instruments.

Spring Drive

Seiko Spring DriveSpring drive watch
The Spring Drive uses a conventional mainspring and barrel along with automatic and/or stem winding to store energy, just as in a traditional mechanical watch. However, the conventional escapement and balance wheel in traditional mechanical watches is replaced by Seiko's Tri-synchro Regulator system, a phase-locked loop wherein a rotor, which Seiko refers to as a "glide wheel", is powered by the mainspring barrel via a stator. The "glide wheel" in turn powers a reference quartz crystal and accompanying integrated circuit which controls an electromagnetic brake which then regulates the rotational speed of the "glide wheel".

They were powered by spring mechanisms similar to those of clocks. Mechanical clocks were introduced into Japan by Jesuit missionaries or Dutch merchants in the sixteenth century. These clocks were of the lantern clock design, typically made of brass or iron, and used the relatively primitive verge and foliot escapement. These led to the development of an original Japanese clock, called Wadokei. Neither the pendulum nor the balance spring were in use among European clocks of the period, and as such they were not included among the technologies available to the Japanese clockmakers at the start of the isolationist period in Japanese history, which began in 1641.
