No. 11465.—21st March, 1899.—HARRY PHILLIPS DAVIS, of 327, Neville Street, Pittsburg, Pennsylvania, United States of America, Electrical Engineer, and FRANK CONRAD, of 709, Whitney Avenue, Wilkinsburg, Pennsylvania aforesaid, Electrical Engineer. Improvements in electric motors and meters adapted for use with alternating currents.

Claims.—(1.) An electric motor or meter constructed and operating substantially as described. (2.) In an electric meter of the kind described, a closed circuit coil, which is acted upon inductively by the current flowing through one of the magnetizing coils so as to distort the magnetic field passing through the secondary member, and thereby cause a tendency for the secondary member to rotate sufficient to overcome the mechanical friction of the pivots.

No. 11466.—21st March, 1899.—BENJAMIN GARVER LAMME, of 230, Stratford Avenue, Pittsburg, Pennsylvannia, United States of America, Electrical Engineer. Improvements relating to the conversion and distribution of electric currents.

Claims.—(1.) For polyphase currents, a rotary transformer having a rotary or stationary multipolar field-magnet either without magnetizing coils or provided with coils each wound in a closed circuit or forming part of a closed circuit, and a rotary armature wound with coils, to which the polyphase current mains are connected, substantially as described. (2.) For polyphase currents, a rotary transformer having a rotary or stationary multipolar field-magnet, and a rotary armature wound with coils, the width of each coil being considerably less than the distance between the centres of the field-magnet poles, for the purpose specified. (3.) A rotary field-motor having a primary member provided with a winding, each coil of which embraces a circumferential core-space the width of which is either materially greater or materially less than that obtained by dividing the whole circumference by the number of poles, substantially as described for the purpose specified. (4.) A system of distribution in which translating-devices arranged on a three-wire or similar system are fed from the direct-current side of a rotary transformer supplied with energy from a stationary transformer or auto-transformer to a point intermediate of the terminals of which the neutral wire of the three-wire or like system is joined. (5.) The system of operating an electric motor at different speeds by reducing its counter electro-motive force substantially as described. (6.) The improved rotary transformer or rotary field-motor, constructed substantially as described with reference respectively to Figs. 1 to 4 or to Fig. 6 of the drawing. (7.) The various systems of distribution described with reference to Figs. 23 to 26 of the drawings.

No. 11480.—23rd March, 1899.—EMIL KREUSER, of Mechernich, Rhine Province, Germany, Retired Director of Royal Mines. Improvements in electro-magnetic apparatus for separating ores.

Claims.—(1.) An electro-magnetic ore-separator, consisting of two opposite revolving iron cylinders of ⊥ or ⊥ shaped section, and wound as bar magnets, the said cylinders being arranged either vertically or in an inclined position one above the other, and the polar distance between the cylinders being maintained by means of abutting distance-rings substantially as described. (2.) In an electro-magnetic ore-separator such as is referred to in the first claim, arranging the polar distance-rings so as to be changeable, in order to enable the polar distance to be varied substantially as described. (3.) In an electro-magnetic ore-separator such as is referred to in the first and second claims, utilising the said polar distance-rings as frictional gear for transmitting the rotary motion imparted to the one magnet cylinder to the other one, so that by employing distance-rings of different diameters for the two cylinders their relative speeds can be correspondingly varied, substantially as described. (4.) In an electro-magnetic ore-separator such as is referred to in the first claim, forming the polar surfaces of the upper cylinder with flutings or milling, and covering the polar surfaces of the lower cylinder with diamagnetic material in order to increase the magnetic action of the upper roller upon the ore, substantially as described. (5.) In an electro-magnetic ore-separator such as is referred to in claims 1 to 4 providing inclined shoots for receiving the separated ores, which shoots are adjutably arranged to extend to the strongest magnetic field between the cylinder magnets, substantially as described. (6.) In an electro-magnetic ore-separator such as is referred to in the preceding claims, arranging only the upper magnet cylinder to act as an electro-magnet, while the lower iron cylinder, constructed without a diamagnetic covering, is made to serve as an armature, substantially as described. (7.) In an electro-magnet ore-separator such as is referred to in the preceding claims, arranging the magnet cylinders both with end poles and with an intermediate pole, which is made of a less diameter or greater diameter than the end poles, whereby the separate polar distance-rings are dispensed with, substantially as and for the purpose described. (8.) In an electro-magnetic ore-separator operating with two magnet cylinders, increasing the useful effect of the pair of magnet cylinders by arranging them vertically or in an inclined position one above the other, the combination therewith of a diamagnetic covering for the lower cylinder poles, on to which the crushed ore is directly delivered, the upper cylinder alone serving to attract the ore, and having its polar surfaces formed with flutings or milling, while the distance between the poles of the cylinders is regulated by polar distance-rings which at the same time serve to transmit the rotary motion from the one magnet cylinder to the other, substantially as described.

No. 11485.—27th March, 1899.—PETER STEPHENSON, of Greymouth, New Zealand, Seaman. An improved fire-escape.

Claims.—(1.) The use of the upper block A, as described, to retard the motion of wire-ropes in fire-escapes. (2.) The use of the hardwood brake B, as described, to retard, control, regulate, and stop the motion of wire-ropes, especially those of small size. (3.) The use of the whole apparatus, as described, as an improved fire-escape.

Improvements in or relating to the treatment of ores, and the precipitation of precious metals from their cyanide-solutions.

Claims.—(1.) In the treatment of ores or tailings containing the precious metals, the employment of metallic carbides which produce a hydrocarbon gas when brought into contact with water. (2.) In the treatment of ores or tailings containing the precious metals, the employment of acetylene or similar hydrocarbon gas. (3.) In the precipitation of the precious metals from their cyanide-solutions, the employment of acetylene or similar hydrocarbon gas, with or without oxygen. (4.) The precipitation of the precious metals by the addition of a metallic carbide, which produces a hydrocarbon gas when brought into contact with water, to their cyanide-solutions. (5.) The treatment of ores or tailings containing the precious metals by finely dividing the ore, mixing it with a metallic carbide, which produces a hydrocarbon gas when brought into contact with water, and moistening the mixture substantially as described.
