  • White Paper: the KCC Scientific Model 1900W-UNV Clock Winder for Standard Electric Clocks Ken Reindel, KCC Scientific Updated 1-26-13
    White Paper: The KCC Scientific Model 1900W-UNV Clock Winder For Standard Electric Clocks Ken Reindel, KCC Scientific Updated 1-26-13 The purpose of this White Paper is to help provide some background on Standard Electric Time master clock, what a Model 1900W-UNV Clock Winder can do for it, and how the Model 1900W-UNV works. Historical Perspective. From the 1880s and beyond, inventors became interested in applying the principles of telegraphy to horology. The idea of a battery-wound master clock which would drive multiple slave clocks, effectively communicating the time signal to them, began to take shape. Additionally, it became fascinating to inventors that the “slave” clocks could be very simple with no escapements or springs, no internal batteries, and requiring little if any maintenance. Charles Warner, who founded the Standard Electric Time Company in 1884,1 was one such inventor. Very early on, Standard Electric borrowed heavily from the Self Winding Clock Company for the design of its master clock movements. Master clocks would have the characteristics described above and relied on special contacts to drive the slaves. Later on, this same concept would be extended to driving program wheels and punched tape ribbons within the clocks themselves, to provide bell timing and other electrical sequences to businesses, schools, etc. For example, many such clocks have been found in schoolhouses and were at one time responsible for ringing bells at the proper times throughout different parts of the building to send students to the next class, as well as driving classroom slave clocks. Standard Electric’s master clock movements eventually took a shape similar to that of the slave clocks: simple, elegant minute impulse ratchet designs for winding the 60, 72, or 80 beat pendulum movements.

  • Remembering the First Battery-Operated Clock
    © 2015 Antiquarian Horological Society. Reproduction prohibited without permission. ANTIQUARIAN HOROLOGY Remembering the first battery-operated clock Beverley F. Ronalds* Francis Ronalds invented a reliable electric clock in 1815, twenty-five years before Alexander Bain’s patent. It was powered by dry piles, a modified form of battery that has extremely long life but the disadvantage that its electrical properties vary with the weather. Ronalds had considerable success in creating regulating mechanisms for his clock to ensure accurate time-keeping in all meteorological conditions. He did not go on to commercialise his ideas, although others made and sold comparable timepieces on the Continent. This year marks the bicentenary of the with the electrically dissimilar metals. The publication of the first battery-operated dry pile was found to have an electric clock. It was rediscovered in the 1970s by potential difference or voltage across its two Charles Aked, Council member of the ends but, unlike Volta’s pile, did not exhibit Antiquarian Horology Society and first an electric current when the terminals were Chairman of the Electrical Horology Group, joined in a circuit.

  • Oscillations[2] 2.0.Pdf
    Team ______________ ______________ Oscillations Oscillatory motion is motion that repeats itself. An object oscillates if it moves back and forth along a fixed path between two extreme positions. Oscillations are everywhere in the world around you. Examples include the vibration of a guitar string, a speaker cone or a tuning fork, the swinging of a pendulum, playground swing or grandfather clock, the oscillating air in an organ pipe, the alternating current in an electric circuit, the rotation of a neutron star (pulsars), neutrino oscillations (subatomic particle), the up and down motion of a piston in an engine, the up and down motion of an electron in an antenna, the vibration of atoms in a solid (heat), the vibration of molecules in air (sound), the vibration of electric and magnetic fields in space (light). The Force The dynamical trademark of all oscillatory motion is that the net force causing the motion is a restoring force. If the oscillator is displaced away from equilibrium in any direction, then the net force acts so as to restore the system back to equilibrium. Definition: A simple harmonic oscillator is an oscillating system whose restoring force is a linear force − a force F that is proportional to the displacement x : F = − kx . The force constant k measures the strength of the force and depends on the system parameters. If you know the force constant of the system, then you can figure out everything about the motion. Examples of force constants: k = K (mass on spring of spring constant K), k = mg/L (pendulum of length L), k = mg/D (wood on water, submerged a distance D).

  • Time in the Theory of Relativity: on Natural Clocks, Proper Time, the Clock Hypothesis, and All That
    Time in the theory of relativity: on natural clocks, proper time, the clock hypothesis, and all that Mario Bacelar Valente Abstract When addressing the notion of proper time in the theory of relativity, it is usually taken for granted that the time read by an accelerated clock is given by the Minkowski proper time. However, there are authors like Harvey Brown that consider necessary an extra assumption to arrive at this result, the so-called clock hypothesis. In opposition to Brown, Richard TW Arthur takes the clock hypothesis to be already implicit in the theory. In this paper I will present a view different from these authors by taking into account Einstein’s notion of natural clock and showing its relevance to the debate. 1 Introduction: the notion of natural clock th Up until the mid 20 century the metrological definition of second was made in terms of astronomical motions. First in terms of the Earth’s rotation taken to be uniform (Barbour 2009, 2-3), i.e. the sidereal time; then in terms of the so-called ephemeris time, in which time was calculated, using Newton’s theory, from the motion of the Moon (Jespersen and Fitz-Randolph 1999, 104-6). The measurements of temporal durations relied on direct astronomical observation or on instruments (clocks) calibrated to the motions in the ‘heavens’. However soon after the adoption of a definition of second based on the ephemeris time, the improvements on atomic frequency standards led to a new definition of the second in terms of the resonance frequency of the cesium atom.

  • Variable Time and the Variable Speed of Light Edward G
    Variable Time and the Variable Speed of Light Edward G. Lake Independent Researcher August 14, 2018 [email protected] Abstract: Einstein’s Special and General Theories of Relativity state that time is a variable depending upon motion and gravity. The theories also state that the speed of light is variable. Einstein’s theories are being verified virtually every day. Yet, a few physicists still argue that time does not vary, and many physicists appear to inexplicably argue that Einstein’s theories state that the speed of light is invariable. This is an attempt to clarify what Einstein wrote and show how experiments routinely confirm that the speed of light is variable. Key words: Speed of Light; Time; Time Dilation; Relativity; Einstein. I. Measuring the speed of light. The fact that the speed of light is variable is demonstrated almost every day. No matter where you measure the speed of light, if you measure it correctly, you will get a result of 299,792,458 meters per second. Does this mean that the speed of light is the same everywhere? No. It means the speed of light per second is the same everywhere. And, according to Einstein’s Theories of Special and General Relativity, the length of a second can be different almost everywhere. That means that if you measure the speed of light to be 299,792,458 meters per second in one location, and if you also measure it to be 299,792,458 meters per second in another location, if the length of a second is different at those two locations, then the speed of light is also different.
