An A4-size Gestetner offset-printing machine. The Gestetner is a type of duplicating machine named after its inventor, David Gestetner (1854–1939). During the 20th century, the term Gestetner was used as a verb—as in Gestetnering. [1] The Gestetner company established its base in London, filing its first patent in 1879.
The pointing machine is used for making one-to-one copies of existing sculptures and to reproduce models made of plaster, modeling clay or modeling wax in materials like stone or wood. It is not possible to use a pointing machine to produce enlarged or reduced copies; the traditional instruments for this are a set of calipers or a three ...
Vickers values are generally independent of the test force: they will come out the same for 500 gf and 50 kgf, as long as the force is at least 200 gf. [6] However, lower load indents often display a dependence of hardness on indent depth known as the indentation size effect (ISE). [ 7 ]
The Rockwell test does not use any optical equipment to measure the hardness indention, rather all calculations are done within the machine to measure the indention in the specimen. [ 13 ] The equation for Rockwell hardness is H R = N − h ∗ d {\displaystyle HR=N-h*d} , where d is the depth in mm (from the zero load point), and N and h are ...
Deus ex machina in Euripides' Medea, performed in 2009 in Syracuse, Italy; the sun god sends a golden chariot to rescue Medea.. Deus ex machina (/ ˌ d eɪ ə s ɛ k s ˈ m æ k ɪ n ə, ˈ m ɑː k-/ DAY-əs ex-MA(H)K-in-ə, [1] Latin: [ˈdɛ.ʊs ɛks ˈmaːkʰɪnaː]; plural: dei ex machina; 'God from the machine') [2] [3] is a plot device whereby a seemingly unsolvable problem in a story is ...
For planar piezoelectric crystals, φ takes the value φ = Ae/d q, where A is the effective area, e is the piezoelectric stress coefficient [28] (e = 9.65·10 −2 C/m 2 for AT-cut quartz) and d q is the thickness of the plate. The transformer often is not explicitly depicted.
The Blanchard lathe, invented by Thomas Blanchard, revolutionized the process of gun stock making in the 1820s, after it was invented. [3] Blanchard's copying lathe traced a model to turn gun stocks, producing the desired contour automatically. [4]
