Patent GB-190228487-A (GB)
Title: Improvements in Means for Controlling Variable Speed Dynamos
Inventor: LEITNER HENRY
Filed: 1902-12-24
Granted: 1903-11-05
Abstract: 28,487. Leitner, H., and Lucas, R. N. Dec. 24. Dynamos, regulating.-Consists of a device for controlling dynamos which are liable to be driven at variable speeds, such as those actuated from the axles of railway trains or by wind power, whereby more or less resistance is put in series with the field winding or windings by means of a centrifugal governor or equivalent device. As applied to a shunt-wound machine a, one end l of the field winding is connected with a brush b and the other end through a long resistance wire f, arranged, as shown, with contacts at different parts of its length; through a lever d by way of a contact-piece d<1>, and thence to the other brush b<1> by way of a lead l<2>. The governor does not appreciably move the lever d, by means of a sleeve c' attached to them both, until the dynamo has attained the speed which gives its normal voltage. An increase of speed causes more of the resistance wire f to be put in series with the feld winding, and a diminution withdraws it. The contacts must be so arranged as to put in the right amount of resistance wire f for the changing speeds. With a serieswound dynamo, the resistance f may be employed to shunt the series windings, and, with a compound-wound machine, it may be used to shunt the series winding as well as to vary the resistance in series with the shunt winding. The resistance wire may revolve with the governor, and be varied by a contact revolving with it controlled by the governor. The Provisional Specification describes a method in which the wire is arranged preferably spirally on a disc, a number of contacts on the wire being brought out approximately radially along the disc, which revolves with the governor by suitable connections, either at the same speed as the dynamo or at a speed proportional to it. Current is brought to the wire at the centre of the disc by means of a brush and slipring or other means, and similarly to the governor ; or one or other may receive current from a brush on the shaft. The contact on the governor is near the centre of the disc when the dynamo starts, and, as it moves out radially when the dynamo speeds up, more and more resistance is introduced into the field circuit. The contact on the governor is of sufficient width to bridge two or more contacts on the disc so as to prevent any break in the circuit. To counteract the gyrostatic effects of high speeds, the resistance wire may be similarly arranged on a slightly-hollow cone, so as to increase the pressure between the wire and governor contacts as the latter moves out from the centre. A solenoid or other electromagnetic device may be used to operate the movable contact across the disc. The resistance wire may be embedded in insulating- material or otherwise suitably insulated if desired.

Title: Improvements relating to Wireless Telegraphy.
Inventor: BROWN SIDNEY GEORGE
Filed: 1903-06-25
Granted: 1904-06-25
Abstract: 14,190. Brown, S. G. June 25. Telegraphs.-The receiving-circuit of a wireless telegraphic system includes a pair of positive and negative contacts b, a, Fig. 4, of which one, preferably the lower, consists of lead oxide or peroxide, such as occurs on secondary-battery positive plates, on a lead base, and the other of lead, copper, mercury, or other suitable metal. These contacts are connected in a local circuit containing a battery d and a galvanometer relay, or a telephone e and the suspended coil f of a direct-writing receiver. The contacts a, b may be cut out of circuit at the contacts ax, b<x> oi a hand-switch, the contacts ax, b<x> being connected, as shown, to the aÙrial and ground wires i, k, or vice versÔ. The current in the local circuit is varied by the action of the Hertzian waves on the contacts a, b. When the contact a is of mercury, it is sealed in a tube which may be tilted to vary the pressure on the contact b. The contacts a, b are preferably dry, and may be placed in a vacuum or in oxygen &c. or under paraffin, oil, wax, water, or an electrolyte, or may be soaked in oil or wax; the action may be steadied by shunting the contacts with a condenser, and the contacts may be heated or cooled. Both contacts may otherwise be of lead coated with lead oxide or peroxide, or a flake of lead peroxide may be placed between two lead contacts; antimony, manganese, manganese dioxide, and bismuth peroxide may also be used, or the negative contact a may be of lead coated with reduced lead oxide from a secondary-battery negative plate. The contacts a, b are arranged, in the " radioscope " shown in Figs. 1 and 2, within a metal case c and on a pillar a<3>, the lower contact b being adjustable vertically by a screw b<3> acting on the collar b' carrying it, and the upper contact a by a clamping-screw a<4> which secures its slotted spring carrier a<1>. Contacts d<1>, d<2>, e', i, k on the base are arranged to be connected to the circuits as shown in Fig. 4, and a switch h is provided for throwing the apparatus into or out of operation. When the switch h is in the position shown in Fig. 2, the contacts a, b are in circuit, but, if it is moved towards the right, the circuit is broken at the contacts a<x>, bx and a circuit is completed through a contact a<0> and the frame of the instrument to the ordinary spark-coil appliances s used in transmitting signals. The peroxide may be produced commercially by electrolysis, and applied to a platinum base. The contact b is conveniently formed from a small piece of a thin sheet of lead upon which the oxide has been deposited in an electrolytic cell. The life of the contact is increased if the sheet lead is burnished before treatment in the cell and if the dilute acid is maintained at its boiling point from the time the deposit begins to form until the deposition is finished ; a small current only is used in this case. The deposit obtained may be polished slightly by rubbing before being used.

Title: Improvements in Trolleys for Electric Traction.
Filed: 1903-08-04
Granted: 1903-10-08
Abstract: 16,939. Lake, H. H., [Trolley Supply Co.]. Aug. 4. Collectors.-- R elates to an automatic spring actuated reel f o r arresting and pulling down the trolley by means of the rope, when it leaves the trolley wire. Fig.1 shows a vertical and Fig. 2 a horizontal section of the arrangement. It consists of a weak spring 10 which is connected to the reel 19, and a stronger one 15 which is fixed to the casing at its outer end, and to the arbor 14 and disc 12 by a ratchet arrangement. When the trolley leaves the wire, the reel commences to revolve rapidly, throwing the pawls 66, into the position indicated by broken lines in Figs. 3 and 4. The pawls catch the lever 61 and press it forward, thus forcing the bolt 43 inwards to liberate the locking-lever 34. The spring 35 presses this lever round so that its projections 32, 33 force out the bolts 29, which, engaging with the teeth 42 on the reel, connects the two springs which pull the trolley down. After the bolt 43 has been pressed inwards, it engages with the groove on the disc 12, shown in Fig. 6, and is drawn further inwards. When the trolley is being pulled down, the motion of the reel and disc 12 is reversed, thus forcing the bolt 43 outwards again into its position for disengaging the two springs. The tension of the reel spring is adjusted to keep the rope just taut when the trolley is on the wire. The casing can be quickly fixed in a frame 75 on the car by the device shown in Figs. 8 and 9. The projection 81 is pressed in the slot 79, and the casing turned so that the projection passes into the inner groove 80, and the whole is then locked by the latch 82 and spring 84.
