Speed Indicator. THE SPEED INDICATOR. Four hemispherical cups A are mounted on four radiating arms B, which are secured to a vertical stem C, and adapted to rotate in suitable bearings in a case, which, for convenience in explaining, is not shown. On the lower end of the stem C, is a small bevel pinion, which meshes with a smaller bevel pinion within the base.
The head of this crank-pin is first made spherical, then faced off at an angle with the axis of b, and in the sloping face is firmly fixed the long screw, S, forming the support for the moon, M, which is caused to rotate about the axis of S, by means of the wheel, F, equal to and engaging with D. The upper end of S projects slightly through a perforation in the moon, and to it the hemispherical black shell or cap, G, is fixed by the screw, K; this cap represents the unilluminated part of the moon, and since G, s, b, and B, are in effect but one piece, the cap moves precisely as the crank does.
If you wish to give me a real proof of friendship, have the kindness to write out for me such an abstract, and I shall have a hemispherical map colored for myself accordingly and add it to Lesage's Atlas, since, in view of my residence abroad for so much of the year, I am compelled to think more and more of my general need of a compendious and tabulated traveling library.
And, since a ray perpendicular to a plane, and coming from a very distant source of light, is nothing else, according to the precedent Theory, than the incidence of a portion of the wave parallel to that plane, I supposed the straight line RC, parallel and equal to AB, to be a portion of a wave of light, in which an infinitude of points such as RHhC come to meet the surface AB at the points AKkB. Then instead of the hemispherical partial waves which in a body of ordinary refraction would spread from each of these last points, as we have above explained in treating of refraction, these must here be hemi-spheroids.
The cause was tried, and the tribunal condemned the offender. We find near Turmero and the Hacienda de Cura other zamangs, having trunks larger than that of Guayre, but their hemispherical heads are not of equal extent. The culture and population of the plains augment in the direction of Cura and Guacara, on the northern side of the lake.
The vault, if there was one, over the semi-circular exedrae must have been hemispherical. From the number of roofing tiles of local stone, shaped into hexagons, found, I think these arcades were roofed in with them, placed overlapping each other, giving a very good effect.
Sometimes it is a troop of stout Franciscan friars, in sandals and brown robes, each carrying his staff and wearing a brown broad-brimmed hat with a hemispherical crown. Sometimes it is a band of young theological students, in purple cassocks with red collars and cuffs, let out on a holiday, attended by their clerical instructors, to ramble in the Cascine.
Such an array of beards! spade-shaped, hammer-shaped, dagger-shaped, triangular, square, peaked, round, hemispherical, and forked. But chief among them all, was old Ushant's, the ancient Captain of the Forecastle. Of a Gothic venerableness, it fell upon his breast like a continual iron-gray storm. Ah! old Ushant, Nestor of the crew! it promoted my longevity to behold you.
A heavy block of granite forms the summit of this pier, and on this block rests the equatorial telescope. Around this structure a circular tower is built, with two or more floors which come close up to the pier, but do not touch it at any point. It is crowned with a hemispherical dome, which, I may remark, half realizes the idea of my egg-shell studio.
The anemometer of the "Robinson" type, having four little hemispherical cups revolving horizontally, furnishes the first hint of another principle of construction adapted to the generation of electricity.
