19. Power to apply this Act to other fluids. THE SCHEDULE. 74 Petroleum, [ACT VIII ACT No. VIII of 1831. PASSED BY THE GOVERNOR GENERAL OF INDIA IN COUNCIL. (Received the assent of the Governor General on the 5th February, 1881.) 19. The Governor General in Council may, from time to time, by notification in the Gazette of India, apply the whole or any portion of this Act to any inflammable fluid other than petroleum, and may by such notification fix, in substitution for the quantities of petroleum fixed by sections four, five and eight, the quantities of such fluid to which these sections shall apply. The Governor General in Council may by a like notification cancel any notification issued under this section. --- THE SCHEDULE. Specification explanatory of the Test Apparatus. The following is a description of the details of the apparatus: The oil-cup consists of a cylindrical vessel 2" diameter, 2 1/6" height (internal), with outward projecting rim 5/16" wide, 3/8" from the top and 17/8" from the bottom of the cup. It is made of gun-metal or brass (17 B. W. G.), tinned inside. A bracket, consisting of a short stout piece of wire, bent upwards and terminating in a point, is fixed to the inside of the cup to serve as gauge. The distance of the point from the bottom of the cup is 11/2". The cup is provided with a close-fitting overlapping cover made of brass (22 B. W. G.) which carries the thermometer and test-lamp. The latter is suspended from two supports from the side by means of trunnions, upon which it may be made to oscillate: it is provided with a spout the 1881.] Petroleum. 81 the mouth of which is ⅓" in diameter. The socket which is to hold the thermometer is fixed at such an angle, and its length is so adjusted, that the bulb of the thermometer, when inserted to its full depth, shall be 1½" below the centre of the lid. The cover is provided with three square holes, one in the centre ⅕" by ⅔", and two smaller ones, ⅕" by ⅕", close to the sides and opposite each other. These three holes may be closed and uncovered by means of a slide moving in grooves, and having perforations corresponding to those on the lid. In moving the slide so as to uncover the holes, the oscillating lamp is caught by a pin fixed in the slide, and tilted in such a way as to bring the end of the spout just below the surface of the lid. Upon the slide being pushed back so as to cover the holes, the lamp returns to its original position. Upon the cover, in front of, and in line with, the mouth of the lamp, is fixed a white bead the dimensions of which represent the size of the test flame to be used. The bath or heated vessel consists of two flat-bottomed copper cylinders (24 B. W. G.), an inner one of 3" diameter and 2½" height, and an outer one of 5½" diameter and 5⅔" height; they are soldered to a circular copper plate (20 B. W. G.) perforated in the centre, which forms the top of the bath, in such a manner as to enclose the space between the two cylinders, but leaving access to the inner cylinder. The top of the bath projects both outwards and inwards about ⅔", that is, its diameter is about ⅔" greater than that of the body of the bath, while the diameter of the circular opening in the centre is about the same amount less than that of the inner copper cylinder. To the inner projection of the top is fastened, by six small screws, a flat ring of ebonite, the screws being sunk below the surface of the ebonite to avoid metallic contact between the bath and the oil-cup. The exact distance between the sides and bottom of the bath of the oil-lamp is 1½". A split socket similar to that on the cover of the oil-cup, but set at a right angle, allows F 82 Petroleum. [ACT VIII allows a thermometer to be inserted into the space between the two cylinders. The bath is further provided with a funnel, an overflow pipe, and two loop handles. The bath rests upon a cast-iron tripod stand, to the ring of which is attached a copper cylinder or jacket (24 B. W. G.), flanged at the top, and of such dimensions that the bath, while firmly resting on the iron ring, just touches with its projecting top the inward-turned flange. The diameter of this outer jacket is 6½". One of the three legs of the stand serves as support for the spirit-lamp, attached to it by means of a small swing bracket. The distance of the wick-holder from the bottom of the bath is 1". Two thermometers are provided with the apparatus, the one for ascertaining the temperature of the bath, the other for determining the flashing-point. The thermometer for ascertaining the temperature of the water has a long bulb and a space at the top. Its range is from about 90° to 190° Fahrenheit. The scale (in degrees of Fahrenheit) is marked on an ivory back fastened to the tube in the usual way; it is fitted with a metal collar fitting the socket, and the part of the tube below the scale should have a length of about 3½" measured from the lower end of the scale to the end of the bulb. The thermometer for ascertaining the temperature of the oil is fitted with collar and ivory scale in a similar manner to the one described. It has a round bulb, a space at the top, and ranges from about 55° F. to 150° F.; it measures from end of ivory back to bulb 2½". Directions for applying the Test.
