Vegetable Teratology An Account of the Principal Deviations from the Usual Construction of Plants The attracting masses were 12-in. lead spheres and as attracted balls he used various masses, lead, zinc, glass, ivory, platinum, hollow brass, and finally the torsion rod alone without balls. Encyclopaedia Britannica, 11th Edition, Volume 12, Slice 4 "Grasshopper" to "Greek Language" 2011-11-28T03:00:19.517Z In employing torsion, the end of the vessel is caught with forceps, and the terminal portion twisted round several times. Manual of Surgery Volume First: General Surgery. Sixth Edition. The torsion of silk, though exceedingly small, is quite sufficient to upset the working of any delicate instrument, because it is never constant. Scientific American Supplement, No. 717, September 28, 1889 No torsion in the peristome; undulating membrane is confined to the posterior part of peristome Genus Blepharisma 3. Marine Protozoa from Woods Hole Bulletin of the United States Fish Commission 21:415-468, 1901 Morren draws a distinction between spiral-torsion or spiralism and the less regular torsion spoken of in the preceding section; in the former case not only is the axis twisted, but its constituent fibres also. Vegetable Teratology An Account of the Principal Deviations from the Usual Construction of Plants A slight torsion or twist is given to the gold spring to cause it to bend with a true curvature in the act of allowing the discharging pallet to pass back after unlocking. Watch and Clock Escapements A Complete Study in Theory and Practice of the Lever, Cylinder and Chronometer Escapements, Together with a Brief Account of the Origin and Evolution of the Escapement in Horology Treatment.—If hæmorrhage is still going on, it must be arrested by pressure, torsion, or ligature, as the accumulation of blood in a wound interferes with union. Manual of Surgery Volume First: General Surgery. Sixth Edition. This is because the torsion varies as the fourth power of the diameter. Scientific American Supplement, No. 717, September 28, 1889 And of these machine tools none, or few at least, except those mounted upon a single pedestal, are free from detrimental torsion where the floor upon which they rest is distorted by unequal loading. Scientific American Supplement, No. 643, April 28, 1888 Spiral torsion of the axis would likewise bring about analogous results. Vegetable Teratology An Account of the Principal Deviations from the Usual Construction of Plants The customary frame, strut rods, and torsion rods had been supplemented by the most extraordinary criss-cross of angle-iron braces it has ever been my fortune to behold. The Killer During the twisting some sections took far more torsion than others. Among the Forces It is therefore evident how great is the advantage of reducing the size of a torsion wire. Scientific American Supplement, No. 717, September 28, 1889 It is known that Cavendish was the first who succeeded by means of the torsion balance in effecting fairly precise measurements. The New Physics and Its Evolution The torsion thread itself was not of metal, but glass, according to the excellent suggestion of the late Dr. Ritchie236. Experimental Researches in Electricity, Volume 1 Cavendish, use of the torsion balance to determine the mean density of the Earth, 170. COSMOS: A Sketch of the Physical Description of the Universe, Vol. 1 The method of suspension of the dynamometer allows it to take automatically the inclination of the line of traction without any torsion of the plates. Scientific American Supplement, No. 787, January 31, 1891 To show how the torsion of wires or threads is made use of in measuring forces, I have arranged what I can hardly dignify by the name of an experiment. Scientific American Supplement, No. 717, September 28, 1889 From the knowledge of this torsion the rigidity can be deduced. The New Physics and Its Evolution Electrometer.—The measuring instrument I have employed has been the torsion balance electrometer of Coulomb, constructed, generally, according to his directions235, but with certain variations and additions, which I will briefly describe. Experimental Researches in Electricity, Volume 1 Reich, mean density of the earth, as ascertained by the torsion balance, 170; temperature of the mines in Saxony, 174. COSMOS: A Sketch of the Physical Description of the Universe, Vol. 1 I could have dispensed with much of her torsion with great equanimity. Reveries of a Schoolmaster For this reason spun glass is quite unsuitable as a torsion thread; it is impossible to say what the twist is at any time, and therefore what is the force developed. Scientific American Supplement, No. 717, September 28, 1889 He took two equal weights of a salt of radium and a salt of barium, which he made oscillate one after the other in a torsion balance. The New Physics and Its Evolution The lower part was a glass cylinder eight inches in height and eight inches in diameter; the tube for the torsion thread was seventeen inches in length. Experimental Researches in Electricity, Volume 1 None of these depended for their motive force on torsion like the chief engines used in classic times. The Travels of Marco Polo — Volume 2 The torsion or twisting test is useful in determining the toughness of wood. The Mechanical Properties of Wood Including a Discussion of the Factors Affecting the Mechanical Properties, and Methods of Timber Testing To make this evident, the enormous apparatus you see had to be constructed, and then, using a fine torsion wire, a perfectly certain but small effect was produced. Scientific American Supplement, No. 717, September 28, 1889 On the contrary, the torsion balance seems very much alive. Scientific American Supplement, No. 601, July 9, 1887 By these and the adjusting screws on which the whole instrument stands, the glass torsion thread could be brought accurately into the centre of the instrument and of the graduations on it. Experimental Researches in Electricity, Volume 1 The operation completed, the larger bleeding-points should be secured by exerting torsion with the artery forceps, and the surface oozing stayed by frequent dashing with cold water. Diseases of the Horse's Foot The strain produced by torsion or twisting is essentially shear transverse and parallel to the fibres, combined with longitudinal tension and transverse compression. The Mechanical Properties of Wood Including a Discussion of the Factors Affecting the Mechanical Properties, and Methods of Timber Testing It is further valuable in that its torsion is far less than that of a fiber of the same size of metal or even of glass, if such could be produced. Scientific American Supplement, No. 717, September 28, 1889 It is applied in those varieties of the torsion balance in which there are two parallel beams, connected by either four or six wires. Scientific American Supplement, No. 601, July 9, 1887 The upper end of the glass thread was attached, as in Coulomb's original electrometer, to an index, which had its appropriate graduated circle, upon which the degree of torsion was ultimately to be read off. Experimental Researches in Electricity, Volume 1 "The tarnal old thing's bewitched, I believe," said Frank, allowing his sister to interfere and quietly untwist and turn right side out the various parts which he had put wrong by all sorts of torsion. The Atlantic Monthly, Volume 04, No. 21, July, 1859 Figure 20 Effect of torsion on different grades of hickory. The Mechanical Properties of Wood Including a Discussion of the Factors Affecting the Mechanical Properties, and Methods of Timber Testing Even if it is only halved, the torsion is reduced sixteenfold. Scientific American Supplement, No. 717, September 28, 1889 Terrier speaks of splenectomy for torsion or twisting of the pedicle, and such is mentioned by Sir Astley Cooper, who has found records of only four such cases. Anomalies and Curiosities of Medicine It would bear torsion through four revolutions or 1440�, and yet, when released, return accurately to its position; probably it would have borne considerably more than this without injury. Experimental Researches in Electricity, Volume 1 One of the methods consists in continuing the torsion until the part held in the forceps is detached. The Dog Figure 49 Making a torsion test on hickory. The Mechanical Properties of Wood Including a Discussion of the Factors Affecting the Mechanical Properties, and Methods of Timber Testing So great has the difficulty been in finding a fine torsion thread that the attempt has been given up, and in all the most exact instruments silk has been used. Scientific American Supplement, No. 717, September 28, 1889 The axillary artery was seen lying in the wound, pulsating feebly, but had been efficiently closed by the torsion of the machinery. Anomalies and Curiosities of Medicine It might be supposed that the torsion of the wire would appreciably affect the result. Scientific American Supplement, No. 447, July 26, 1884 This consisted simply of a coil of thick conductor suspended by a torsion wire, and opposed laterally to a fixed coil of wire of high resistance. Scientific American Supplement, No. 384, May 12, 1883 Soft iron soon loses the structure, or becomes enfeebled, under the constant to and fro torsions requisite where we desire a constant change of polarity, as described later in the magnetic bells. Scientific American Supplement, No. 392, July 7, 1883 Owing to its fineness, its torsion would be extremely small, and the more so because glass is more easily deformed than metals. Scientific American Supplement, No. 717, September 28, 1889 These are entirely unaffected by the torsion of the interorbital part of the skull. Hormones and Heredity In reality, however, the torsion was very small. Scientific American Supplement, No. 447, July 26, 1884 Heat, ligation, pressure and torsion are the different methods recommended. Common Diseases of Farm Animals We must therefore give it two entire turns or twists to the right, and strongly magnetize it on the north pole of the magnet while under torsion. Scientific American Supplement, No. 392, July 7, 1883 I imagine many physicists must have turned to this material in their endeavor to find a really delicate torsion thread. Scientific American Supplement, No. 717, September 28, 1889 Heat also has a disturbing effect, and makes itself felt in the torsion of the fiber and the cage surrounding the lever. Scientific American Supplement, No. 275, April 9, 1881 Coulomb was the maker of the first instrument for measuring a current, which was known as the torsion balance. Steam, Steel and Electricity This monstrosity, called biastrepsis, consists of strongly marked torsions as are seen in many species with decussate leaves, though as a rule it is very rare. Species and Varieties, Their Origin by Mutation On restoring the wire to its original place, it will be extremely flexible, and we may now superpose several contrary polarities under contrary torsions, as already described. Scientific American Supplement, No. 392, July 7, 1883 To illustrate the movement of torsion in the spine, or its rotation round its own axis. A Practical Physiology The lever placed at equal distances from the fixed balls communicates, by the medium of the torsion wire, with the positive pole of a battery, P, the other pole being to earth. Scientific American Supplement, No. 275, April 9, 1881 Any special occasion of expansion or exuberance, of depression, torsion, or introspection, was sufficient to call it forth. Literary Lapses We have dealt with torsions and fasciations and with seedling variations at some length, in order to point out the phases needing investigation according to recent views. Species and Varieties, Their Origin by Mutation Its free motion differs entirely from that given it by torsion or stress. Scientific American Supplement, No. 392, July 7, 1883 This peculiar change of position requires a considerable amount of torsion in the pulvinus. The Power of Movement in Plants But by the time the flowers have expanded, the five stigmas twist round so as to face the circumference, owing to the torsion of that part of the style which lies beneath the stigma. The Different Forms of Flowers on Plants of the Same Species In the vegetative reproduction of this Veronica the torsion appeared in the first, also in the second and third year, but with diminishing intensity. Darwin and Modern Science More than once I have had occasion to deal with the phenomenon of torsions, as exhibited by the teasels and some other plants. Species and Varieties, Their Origin by Mutation The superposed magnetism then becomes a single directive force, and we can then by a few vibrations or torsions reduce the rod to its ordinary condition. Scientific American Supplement, No. 392, July 7, 1883 The amount of charge in each jar was determined by bringing a proof-plane into contact with its knob and measuring by a torsion balance the charge taken away. Faraday as a Discoverer Thus we can understand the meaning of the torsion of the styles in the long- styled flowers alone, as well as their divergence in the short-styled flowers. The Different Forms of Flowers on Plants of the Same Species Hard steel preserves its structure, but its molecular rigidity is so great that we obtain but mere traces of any change of polarity by torsion.
