Title: Improvements in Process for the Recovery of Precious Metals from Ores and Material containing same.
Inventor: WALKER ARTHUR HENRY
Filed: 1906-02-27
Granted: 1907-02-27
Abstract: 4 7 9 6. Walker, A. H., [Just, J. A.]. Feb. 27. Gold salts; silver salts; copper salts; sulphates; sulphides; chlorides; phosphates. - In a process for recovering gold, silver, and other precious metals from ores &c. without chlorination or roasting, and without the use of a high temperature, the ore is ground and sulphuric acid is added to decompose the baser sulphides present. When the action has ceased, an oxygen-bearing salt and more sulphuric acid are added, and the temperature of the mixture is raised to 180-200 F. The oxygenbearing salt is preferably added in portions at a time, the amount of such portions being increased towards the last stage of the process when the acid is concentrated, loss of oxygen being thereby prevented. The temperature of the mixture never exceeds 250 F. Air is allowed access to the mixture during the whole of the operations. Instead of employing a nitrate and sulphuric acid, nitrosulphonic acid may be used. Phosphoric or other acid may be employed instead of sulphuric acid. In either of these cases, copper is also converted into soluble salts. Whan the mixture has become concentrated to from one-half to one-third of its original volumn, the heating is stopped and the precious metals are found in the solution. The solution is diluted with water or acidulated water, and decanted or filtered. The residue is washed and the washings added to the solution, or they may be used, alone or with sulphuric acid, for diluting the concentrated solution in the original extraction vessel. The gold and silver, or both, may be obtained in the metallic state or as sulphides or other salts from the solution. The silver may be precipitated as chloride, care being taken to avoid access of hydrochloric acid in the solution, and the gold separated in metallic form by iron &c. The sulphuric acid is thus recovered and may be re-used, any ferrous sulphate present being oxidized to ferric sulphate before using.

Title: Improvements in and relating to Apparatus for Automatically Checking and Registering the Issue of Tickets.
Inventor: STOCKALL JAMES JOHN
Filed: 1906-03-05
Granted: 1906-10-18
Abstract: 5319. Stockall, J. J., and Stockall, T. J. March 5. Printing on tickets.-Tickets are endorsed by a printing or perforating machine fitted with means for registering the issue and value of each ticket. A lever g, Fig. 1, with cam-piece c mounted upon a rock-shaft f, operates a plunger b, which carries in addition to the perforators or type a number of circuit - closing devices, connected to counting- apparatus. The shaft is locked by a pawl s acting on a cam v, until the ticket has been fully inserted so as to push back the lever t, controlled bya spring u. The lever moves between stops, and an arm w, Fig. 3, carrying a trip-lever x over a notched segment 2, ensures a full stroke ; the trip-lever is centred by springs y with stops z.

Title: Improvements in and relating to Signal Systems for Railways and the like.
Filed: 1906-10-24
Granted: 1907-09-12
Abstract: 23,686. British Thomson - Houston Co., [General Electric Co.]. Oct. 24. Automatic systems.-The system described in Specification No. 20,542, A.D. 1906, in which both track rails are electrically continuous for both power and signal current, is modified for working on short sections. The relays are connected to the track in pairs between the transformerd which, as in the previous system, supply current of different frequencies, each relay being arranged to respond only to current of one frequency. In the present system, each signal is controlled by one relay only. The train H in the position shown short-circuits the relay F<4>, which is operated by current from the transformer E<3>. The signal G<4> stands at danger' until the train has passed so far beyond the point where the relays F<3>, F<4> are connected to the track that the relay F<4> is energized to close the circuit to the signal mechanism. The relay F<3> is de-energized when the train is approaching the point where it is connected to the track. The sections, therefore, overlap to a certain extent, and this overlap is longer when a train approaches a block from the relay end than when it approaches from the transformer end. To prevent a signal from moving to 'danger' before a locomotive has passed, the signals are set back from the relays and transformers, and are situated further from the relays than from the transformers.

Abstract: 14,581. Watson, F., Moulding, W., and Howard & Bullough. June 25. Guards; belt forks, operating; starting and stopping gear.-A locking-device for the guards and starting and changing mechanism of machinery comprises a push-bar 1, Figs. 3 and 5, suitably mounted in a bracket 2 and ordinarily kept in its ' out' position by a spring 3. A hinged finger 4 abuts against a spring 5 on the locking-bar 6. In applying the invention to the stripping-cover of a carding-engine, Fig. 1, the locking-bar 6 engages with a stud 7 on the cover guard 8 or other mechanism. Connected to the finger 4 is a flat spring 9 ; if the bar 1 is pushed when the card cylinder 10 is in motion, the spring 9 and finger 4 are carried round as shown in broken lines, Fig. 3 ; but if the cylinder is stationary, the finger 4 presses the spring 5 and puts the rod 6 out of engagement with the guard. A permanent cover 12 is provided. An arrangement is also described whereby the fork 11 cannot move the belt to the fast pulley when the guard is not in position. The connecting-rod 19 operates the lever 18, on which is an obstructing lug 20, Fig. 1. When the guard 8 is lifted, the lug 20 is brought into the path of the strap fork and prevents it from moving so long as the cover guard is open.

Granted: 1908-04-16
Abstract: 27,447. Siemens Bros. Dynamo Works, and Clift, A. S. Dec. 12. ELectricallly - actuated apparatus ; brakes. - In electric winding-apparatus fitted with air or other pressure brakes, the brakes are applied and the power is cut off automatically if the air pressure or the exciting current should fail, or by hand in case of emergency. A cylinder b containing a piston a is connected through a two-way valve m either to the source of pressure or to the atmosphere. The valve may be operated by a handle p, or by the dropping of the armature of the solenoid l. If the air pressure fails, or the valve m is operated, the piston a is forced down by a weighted lever c. The catch d is disengaged, and the hand-lever t is swung over by the weight e, the movement being transmitted by levers and a link to a trip gear h, connected to a valve on the brake cylinder. This valve is opened and the pressure is relieved, the brake being applied by a falling weight. By means of an adjustable pin j on the lever t, the arm k is forced over so as to open a cut-out in the circuit of the motor armature, or of the field of the variablevoltage generator.

Granted: 1909-02-18
Abstract: 1191. Howard, S. Jan. 18. [Patent of Addition to No. 12,738, A.D. 1906.] Automatic instruments.-An expression device by which any note or series of adjoining notes can be distinguished from the rest of a chord by being muted or left unmuted, as described in Specification No. 12.738, A.D. 1906, is arranged to operate pneumatically. A muting-flap e<1>, Fig. 3, is brought into action, or a lever e is moved to shorten the stroke of the piano hammer b, when suction is admitted by a tube k to collapse a pneumatic c, one of these muting-devices being provided for each two notes, or for more than two in the end parts of the register. The tubes k are connected to apertures g, Fig. 2, in a valve box f, which is exhausted through apertures h, and each end of the valve box is fitted with a sliding valve l, which is controlled by a lever at the front of the instrument to admit atmospheric pressure through a groove m to any number of the apertures g. Thus the notes corresponding to the apertures g between the two valves l are muted, the rest being fully sounded ; but the arrangement may be varied to reverse this effect. The valves l are each made in two spring-separated parts to maintain a good fit with the valve box. Alternatively, a rotary form of valve may be used. There may be two valve-boxes for controlling different parts of the register. Pressure may be used instead of suction, and in that case the ends of the valve box may be fitted with exhaust boxes for admitting suction to the grooves m. The pneu. matics c may act on the hammers directly. The invention is applicable to separate players. According to the Provisional Specification, a safety-valve may be provided, and each muting-device may be governed by an independent slide valve.
