Title: Improvements in or connected with the Extraction of Gold from Gold Ores.
Inventor: WORSEY JAMES WESTHEAD
Filed: 1903-06-29
Granted: 1904-09-29
Abstract: 14,398. Worsey, J. W., and Hoal, E. June 29. Gold is extracted from refractory ores &c. by the action of nascent bromide of chlorine, and residual gold is washed out with a solution of ferroprussiate of ammonium and sodium or potassium. For the first treatment, the ore is mixed with a chlorate and bromide of sodium or other alkali, or with a chloride and bromide of an alkaline earth. Dilute hydrochloric, sulphuric, or other acid is added, and the mixture is heated to 150‹ F. and then nearly to the boiling-point. Gold, mixed with lead sulphide, is precipitated from the neutralized solutions by adding a lead salt, followed by sulphuretted hydrogen and agitation with air. The precipitate is treated as usual to recover the gold.

Patent GB-190412667-A (GB)
Title: A New or Improved Appliance for Automatically Recording the Number of Operations of a Machine or other Moving Part.
Inventor: BERRY SAMUEL SIMPSON
Filed: 1904-06-04
Granted: 1905-06-03
Abstract: 12,667. Berry, S. S. June 4. Registering output of, and number and time of working of machines; counting-apparatus; tell-tales for checking servants &c. For recording at a distance electrically the work done or output of a printing; box-making, or other machine, the revolutions of a turnstile, or the rate of progression or stoppages of machines &c., so serving as a tell-tale or check, the recording-apparatus, shown in Fig. 2, and the switch apparatus, shown in Fig. 4, are employed. The drum 7 and its time sheet are driven by suitable clock-work, and the recording- levers 16, Figs. 7 and 9, one for each machine, are actuated by the electromagnets 15 to make strokes on the time sheet. A stroke is made on the record at every operation, or after a definite number of operations. With each impulse of the recording-lever 16, the pawl 26 rotates the wheel 23 and the notched disc 24. This notched disc provides for one stroke in a definite number being of greater length than the others. The extension 14 acts as the pole-piece of the electromagnet 15. As the recording-lever 16 is attracted towards the magnet, the lower end of the lever has a compound movement, towards the magnet and laterally. Associated with each machine is the switch, Fig. 4, operated by a moving or rotary part of the machine. The spring contacts 33 are connected to the recording electromagnet and to a battery. After a number of strokes of the lever 35, the spring-pressed plunger 37, which. is gradually drawn out, is released by the lever 43 slipping over a tooth of the cam-wheel 41. This causes the rubber cap 39 to inflate, and make contact between the contact-blades 33. The fit of the piston 37 is slack so that the deflation of the cap 39 is rapid. The drum 7 carrying the time sheet is provided with the nut 48 on the screw-threaded axle, and the bow spring 49, at the other end, to allow the drum to be adjusted along its axle. The bar 53 holds the recording-levers clear of the drum, when it is turned up. By the use of a divided ring on the drum axle, and two batteries in a divided circuit, one battery is switched on and the other off alternately, to enable them to recuperate.

Title: Improvements in or relating to Friction Driving and Reversing Gear.
Inventor: HAMPSON FRANK GEORGE
Filed: 1904-09-09
Granted: 1905-08-24
Abstract: 19,499. Hampson, F. G. Sept. 9. Driving - gear.- Relates to friction reversing - gearing for launches driven by petroleum-spirit motors and the like. The motor shaft A, Fig. 1, projecting into a fixed casing 0, is secured to a direct driving friction member D with conical driving-surface D', and to a second member E with a conical surface E' for reverse driving. A shell F, sliding on a feather on the driven shaft B, is provided with an internal conical surface F<1> for engaging with the surface D<1>, and with an external surface F' for engaging with conical pinions G. The pinions G are mounted upon studs G' carried by a frame G<2> consisting of inner and outer rings connected by spokes as shown in Fig. 2. The frame G<2> has a slight longitudinal play, but is prevented from rotating by lugs G<3> engaging slots in the casing C. A spiral spring B<3> communicates a thrust to the member F through a ball bearing B<2> which normally keeps the surfaces D', F' in contact for the direct speed. A hand-lever F<4> pivoted at C<3> is forked and connected to a ring F<3> engaging the member F through a ball bearing. When the member F is thrust to the left, the pinions G come into engagement with the rotating surface E', causing the surface F<2> and the shaft B to rotate in the reverse direction. By allowing the frame G<3> to slip inside a brake, the reverse speed may be diminished.

Title: Improvements in Electric Train Control Systems.
Filed: 1904-09-10
Granted: 1905-09-09
Abstract: 19,573. British Thomson-Houston Co., [General Electric Co.]. Sept. 10. Motors, controlling.- Relates to the control of the motors on electricallypropelled cars by successively - operated electromagnetic switches controlled from a masterswitch in the multipleunit system described in Specification No. 24,770, A.D. 1902, and comprises means for preverting resistances from being cut out except when the motor circuit is energized, means for enabling the driver to break the control circuits simultaneously at each car, and also an interlocking contactor construction. As shown in Fig. 1, electromagnetic switches R<1>-R<7> have contacts to bridge the resistances R<a>-R<g> in the motor circuit, and switches S, P, P', in conjunction with the switch B, effect the series and parallel relations of the motors M', M<2>, a throttle magnet coil O, the action of which is explained in Specification No. 26,465, A.D. 1903, reverser switch electromagnets W, W<1>, master-switches K, K<1>, and line contacts T<1>-T<4>. The switches R<1>-R<4> not only cut in or out the resistances, but are provided with other contacts which open and close the retaining- circuits for the other magnets. Included in and controlling the circuits of the switches R<1>-R<4> is a relay Q controlled by current in the motor circuit drawn from the line contact T', the arrangement being such that, when no current flows in the motor circuit, the resistance-controlling circuits are interrupted, Arranged between the motor controller and reversing switch and the train-wires is a cut-out U, shown in section in Fig. 6, having a series of fixed contacts u<1>, u<2>, with terminals u<3>, u<4>, and movable contacts u. When connection is made between these contacts, a spring 16 is placed under tension, but rotation of the contacts u to the 'off' position is prevented by means of a stop U', forming part of the core of a solenoid U<3>, engaging an arm U<2> on the shaft of the contacts U. By operating the switch U<4>, the motorman may at any time cut out the control circuits by energizing the trainwire 6. Fig. 9 shows in detail a main contact and its interlocks, the particular contact represented being the contact B, which is so constructed that during change from series to parallel, which is effected without opening the motor circuit, the series contact S is not opened until the bridging- contact B is fully closed, and the actuating-circuit of the contact B is not broken at b<2> until the maintaining-circuit is made at b<1>. The movable contacts b<10>-b<40>, adapted to engage the fixed contacts b<1>-b<4>, are loosely assembled on a rod 10<1> with intercepted springs 15<1>, 16<1>, their movements being limited by stops 11<1>-14<1>. The lower end of this rod and the movable portion 41 of the contact B are connected to the core 3<1> of the actuating-coil by levers 17<1>, 19<1>, the former by a hook 21<1> on a link pivoted at 8<1>.

Title: Improvements in or connected with Rock Drills.
Inventor: HOLMAN JOHN HENRY
Filed: 1904-09-21
Granted: 1905-07-27
Abstract: 20,390. Holman, J. H., and Holman, J. M. Sept. 21. Rock drills.-In a rock drill, the valve-chest has a special form, and two sets of ball valves in connection with each end of the distributing-valve put the space at each end of the valve in connection with the exhaust twice during each stroke, so that the inlet port is closed before the piston stroke is finished. The valve-chest cover f, Fig. 1, has inclined ends which bear on the wedge-shaped rubber buffers e, the end of the liner b being closed by metal buffer-plates d. Assuming the piston k to be at the right-hand end of the drill cylinder and the valve c at the extreme left, the piston will be impelled forwards until the inclined shoulder, through the medium of the ball j<1>, exhausts the motive fluid from the right of the valve c. The fluid passes through the port o, past the valve j and balls j<1>, i<1>, and finally through the port m<1> into the exhaust port l. The pressure of the fluid being reduced, the valve c moves until it covers the upper end of the port o, and prevents further exhaustion of the motive fluid. The supply through the port n is also cut off. The piston k continues its forward movement and lifts the ball i<1>, which opens the valve i and completes the exhaustion of the fluid from the right of the valve c by way of the ports p, m<1>. The valve c then completes its travel to the right, and the motive fluid passes through the port q to reverse the piston. Fig. 2 shows the body u fitted with independent slides t, in which the drill cylinder is movable by means of a screw, Fig. 1. The grooves v, w of each slide and corresponding face differ in width, so that a fine or coarse adjustment can be obtained by adjusting either slide. The twist spindle Y', Fig. 3, carries springs Y<2> and semicircular pawls Y, and is embraced by the ratchet-wheel z.
