No. 17049.—29th September, 1903.—JOHN JACOB MEYERS, Capitalist, of 520, Parrott Building, CHARLES FRANKLIN HUMPHREY, of 302, Claus Spreckels Building, Attorney-at-Law, JOHN ELISHA SILLS, of 520, Parrott Building aforesaid, all of San Francisco, California, United States of America (assignees of George Clark Richards, of 664, Washington Street, Oakland, California aforesaid, Inventor). Deep-well pump.

Claims.—(1.) The combination with the discharge-tube of a well, of a pump-barrel telescoping with said tube, means for locking the parts together, and a plunger adapted to disengage the barrel from the tube and allow the barrel to be withdrawn to the surface independent of the tube. (2.) A deep-well-pump apparatus characterized by a tubing having a channelled section, a pump-barrel movable in the tubing, a latching device engaging said channelled section for holding the barrel in place, and a plunger adapted to engage said latching device to release the barrel and allow it to be withdrawn through the tubing. (3.) A deep-well pump characterized by a stationary valved pump-barrel section, a discharge-tube, a hollow valved plunger telescoping with the pump-barrel, and hollow removable shoes carried by the plunger and having a tapered edge co-operating with the barrel to clean the parts and prevent wear. (4.) In a deep-well pump, the combination with the pump-barrel, a discharge-tube and plunger, of a relief-valve located in the tube remote from the surface of the well and having a discharge exterior to the tube, and means for operating said valve. (5.) In a deep-well pump, the combination of a pump-barrel, a discharge-tube, a plunger, a plunger-rod, upper and lower valves operable by said plunger-rod, said upper valve comprising two separable sections embracing the plunger-rod and adapted to hold a packing, said valve having symmetrical ends, and having a limited movement in unison with the rod.

No. 17050.—29th September, 1903.—CLINTON EMERSON DOLBEAR, of Terminal Island, Los Angeles, California, United States of America, Chemical Engineer. Process of manufacturing caustic soda.

Claims.—(1.) The method of producing caustic soda from alkali earth, which consists in converting the alkali earth into an alkaline solution, thence subjecting the solution thus formed to the action of caustic lime in order to convert the said solution to a solution of caustic soda, and thence reducing the caustic soda held in solution to a condition of dryness. (2.) The method of producing caustic soda from an alkali in its natural condition, which consists in subjecting a solution of such alkali to the action of caustic lime, whereby the alkali-solution is converted into a solution of caustic soda.
(Specification, 4s.)

No. 17051.—29th September, 1903.—JACOB DAVID WOLF, of 111, Hatton Garden, London, England, Gentleman. Improvements in or relating to the separation of metals from their ores.

Claims.—(1.) In separating mineral constituents of ore from gangue, the employment of oil or grease treated with chloride of sulphur. (2.) The process of separating mineral constituents of ore from gangue, which consists in agitating pulps or the like with oil treated with chloride of sulphur, and running off the floating oil carrying the values. (3.) In separating mineral constituents of ore from gangue, the employment of a mineral oil such as heavy petroleum, mixed with a small proportion of animal or vegetable oil, and thereafter sulfo-chlorinated. (4.) In separating mineral constituents of ore from gangue by means of oil, passing the oil through warm water to remove suspended particles of gangue therefrom. (5.) In separating mineral constituents of ore from gangue, agitating pulps with oil until all the values are taken up, and thereafter passing the oil upwards through a tank of warm water to remove suspended particles of gangue therefrom, substantially as described. (6.) In separating mineral constituents of ore from gangue by means of oil, recovering oil from the waste pulps by blowing up through them currents of air, with or without steam, substantially as described.
