Section 1. Nature of the test-apparatus

(5) the thermometer for indicating the temperature of the oil in the oil-cup; The clockwork arrangement, by which during the operation of testing the slide is withdrawn, and the test-flame dipped into the cup and raised again as the slide is replaced, is provided with a ratchet key for setting it in action for each test, and with a trigger for starting it each time that the test-flame is applied. II.—Directions for drawing the Sample and preparing it for testing. (4) the tripod stand with jacket and spirit-lamp for heating the water-bath; (1) the oil-cup; 1. Nature of the test-apparatus.—The instrument employed is the Abel-Pensky petroleum testing apparatus, fitted with an additional thermometer to indicate the temperature of the oil in close proximity to the walls of the cup. This thermometer has a cylindrical bulb, $\frac{3}{4}$ inch in length and $\frac{5}{16}$ inch in diameter. It is scaled from 45° to 165° Fahrenheit, ten degrees on the scale occupying $\frac{3}{8}$ inch. The thermometer is held vertically in a socket attached to the cover of the oil-cup in such a position that the bulb is $\frac{1}{16}$ inch from the side of the cup. (The thermometer can be removed and the orifice which is provided for it closed by means of an india-rubber plug, if the apparatus is required for testing petroleum in the ordinary way.) (3) the water-bath or heating vessel; (8) the dropping bottle or pipette for replenishing the test-lamp; and (2) the cover, with slide, test-lamp, and clockwork arrangement for opening and closing the holes in the cover and for dipping the test-flame; (7) the thermometer for indicating the temperature of the oil before it is poured into the oil-cup; (6) the thermometer for indicating the temperature of the water in the water-bath; THE FIRST SCHEDULE. TESTING. (See section 3.) I.—Nature of the Test-apparatus. The apparatus consists of the following parts:— The cover is provided with three holes, one in the centre and two smaller ones close to the sides. These are closed and opened by means of a pivoted slide. When the slide is moved so as to uncover the holes, the suspended lamp is caught by a projection fixed on the slide, and tilted in such a way as to bring the end of the spout just below the surface of the lid. As the slide moves back so as to cover the holes, the lamp returns to its original position. Upon the cover, in front of and in a line with the nozzle of the lamp, is fixed a white bead, the diameter of which represents the size of the test-flame to be used. The water-bath or heating vessel is so constructed that, when the oil-cup is placed in position in it, an air-space or air-chamber intervenes between the two: consequently, in applying the test under ordinary circumstances, the heat is transmitted gradually to the oil from the hot water through the 1899.] Petroleum. 109 (The First Schedule.—Testing.) the air-space. The water-bath is fitted with a socket for receiving a long bulb thermometer, to indicate the temperature of the water. It is also provided with a funnel, an overflow-pipe and two handles. The water-bath rests upon a tripod stand, which is fitted with a copper cylinder or jacket, so that the bath is surrounded by an enclosed air-space, which retains and regulates the heat. One of the legs of the stand serves as a support for a spirit-lamp, which is attached to it by a small swing bracket. 1. (1) This Act may be called the Indian Petroleum Act, 1899; and (2) It shall come into force at once. (3) Sections 1 to 3, section 25, and all the provisions of this Act in so far as they relate to dangerous petroleum and the importation of petroleum, extend to the whole of British India. The rest of this Act extends only to such local areas as the Local Government may, by notification in the local official Gazette, direct. 1. Drawing the sample.—In all cases the testing officer or some person duly authorized by him shall personally superintend the drawing of the sample from an original unopened tin or other vessel. An opening sufficiently large to admit of the oil being rapidly poured or cyphoned from the tin or other vessel shall be made. Two bottles, each of the capacity of about forty fluid ounces, are to be filled with the oil. One of these, the contents of which is intended to be preserved for reference in case of need, is to be carefully corked, the cork being well driven home, cut off level with the neck, and melted sealing-wax worked into it. The other bottle may be either stoppered or corked. 1. Preparing the water-bath.—The water-bath is filled by pouring water into the funnel until it begins to flow out at the overflow-pipe. The temperature of the water at the commencement of each test, as indicated by the long bulb thermometer, is to be 130° Fahrenheit, and this is attained in the first instance by 110 Petroleum. [ACT VIII (The First Schedule.—Testing.) by mixing hot and cold water, either in the bath or in a vessel from which the bath is filled, until the thermometer which is provided for testing the temperature of the water gives the proper indication; or the water is heated by means of the spirit-lamp (which is attached to the stand of the apparatus) until the required temperature is indicated.
