(9.) In a distance and course recorder for ships, a square elliptical or sided box within which is a vertical adjustment device, and carrying on the top retaining dogs or pawls adapted to engage recesses in a square elliptical or sided casing, substantially as set forth and as illustrated. (10.) In a distance and course recorder for ships, a square elliptical or sided casing bolted at its lower end to the flange of the flared upper end of the inlet branch of an inverted U-shaped pipe, and fitting at its upper end neatly within a sleeve bolted to the deck of the ship, substantially as and for the purposes set forth and as illustrated. (11.) In a distance and course recorder for ships, and in combination, a rotator having a rod passing through and secured to a bearing-sleeve, and entering a protector-box in which is a stirrup-adjustment device, a cord or chain leading therefrom through guides and terminating in a short rod having a ball working in a cup in the cover and connected with a spring stirrup-adjustment device through which the rotation imparted by the rotator is communicated to the recording-mechanism, substantially as set forth and as illustrated. (12.) In a distance and course recorder for ships, the combination with a meter having a winding-drum adjustably

secured to a spindle of its mechanism of a carrier adapted to slide on bearings in a guideway in a fore-and-aft line with the keel of the vessel, said carrier having grips to engage the chart, substantially as and for the purposes specified and as illustrated. (13.) In a distance and course recorder for ships, a counterbalanced arm bent round abaft and under the compass-basin, said arm being mounted on a standard secured to the compass card, and carrying a recording-pen on teeth on its lower end, substantially as set forth, and illustrated in Fig. 2 of the drawings. (14.) In a distance and course recorder for ships, a modification of the last preceding claiming-clause wherein the counterbalanced arm is bent round within the basin and abaft the compass-card, substantially as set forth, and illustrated in Fig. 4 of the drawings. (15.) In a distance and course recorder for ships, a carrier having longitudinal recesses in the sides and adapted to travel in a fore-and-aft line with the keel of the vessel between a pair of side guide-rods on a table supported from the compass-basin, said carrier having a pair of adjustable grips, each consisting of a block with depending side flanges engaging the sides of the carrier and provided with a clamping thumb-screw and a flat spring adapted to grip the chart, substantially as and for the purposes set forth and as illustrated.

No. 15542.—23rd October, 1902.—THE CLANCY WHITE-LEAD COMPANY PROPRIETARY, LIMITED, whose registered office is at Hyde Street, Footscray, Victoria (assignees of John Collins Clancy, of Hyde Street, Footscray aforesaid, Analytical Chemist and Metallurgist). An improved process for the manufacture of white-lead (basic carbonate of lead) from lead ores.

Claims.—(1.) An improved process for the manufacture of white-lead (basic carbonate of lead) from lead-ores characterized by (a) mixing lead-sulphate (PbSO₃) with the lead-ore, (b) subjecting the mixture to a heating operation in a converter to convert the lead into oxide, (c) leaching with normal acetate-of-lead solution, (d) passing the gaseous products of decomposition (sulphur-dioxide) into a vat containing basic acetate-of-lead solution, so as to precipitate sulphite of lead (PbSO₃) for subsequent use, (e) precipitating basic carbonate of lead (white-lead) by passing carbonic-acid gas through the solvent solution containing the dissolved lead, all substantially as described and explained. (2.) In a process for the manufacture of white-lead from lead-ores, the employment and subsequent regeneration of lead-sulphite, substantially as and for the purposes described. (3.)
