This article traces the construction of an acoustic regime in Renaissance Florence that was based on the casting, placement, and ringing of civic bells. In confronting the formidable but mute power of the defensive towers that dominated the city's skyline in the late middle ages, successive republican governments regulated these private towers with ...

The process drawing is defined as a constant meandering between the consciousness or hunch towards an object and the concept of understanding or rationalizing that object. This falls back to a search for form submitting to critical reflection including both intuition and analysis.With Process Drawing, this reflection initially comes from an ideal ...

Plated armature contacts for solid armature electromagnetic railgun launchers
IEEE Transactions on Magnetics, 1995Solid armature firing tests have shown that, under electromagnetic railgun firing conditions, the armature contact areas wear excessively and after transitioning, lose contact with the rail surfaces. It is desirable to maintain rail contact as long as possible.

To increase the transition velocity of solid fibre brush armatures, launch experiments have been performed with an increased armature height of about 15%. However, results of experiments under equal launch conditions did not show higher transition velocities up till now.

In Direct Current machines, we have two types of windings. The first one is field winding and the second one is armature winding. Armature field, and armature reaction is about armature winding. In this chapter, we discuss the issue of armature field, Geometrical and magnetic neutral axis (G.NA & M.N.A), resultant field at load.

Nonlinearities in balanced armature transducers
The Journal of the Acoustical Society of America, 2020Electromagnetic transducers using a balanced armature play an important role in hearing aids and in-ear headphones because they generate required sound output at high efficiency. This paper investigates the transfer behavior at high amplitudes and develops a lumped parameter model of this transducer that considers the nonlinearities caused by the ...

ABSTRACT The sculptor uses the armature to organize and hold together his plastic art. This armature is not seen on the surface of the work, yet it is crucial to the nature and existance of the art object. Cities and their metropolitan areas are not unlike the work of the sculptor, for they too are held together by an unseen armature.

THE purposes of these investigations were: (1) to determine what the maximum temperatures of the copper and iron were, and to compare those maximum temperatures with thermometer readings; (2) to measure the average of the maximum temperatures by resistance and to compare the results with the average secured from the maximum copper temperatures; (3) to ...

Insulation resistance of armature windings
Electrical Engineering, 1934Insulation resistance of the windings of an electric machine may be used as a barometer for indicating the condition of the windings. On the basis of tests on many machines of different types it is recommended that all insulation resistance readings be taken after the application of 500 volts (d-c) for one minute. The slope of the resistance-time curve

In continuing with the previous chapter which discussed armature reaction, this current chapter discusses armature windings. The authors address the issue of lap windings, method of drawing, and making the direction of current. Moreover, they discuss how to find out the location of brush placement. Then then discuss multiplex lap winding, wave winding,
