Title: Improvements relating to Electrical Conduit Systems for Tramways and Railways
Inventor: ASPINALL FRANK BOULTON
Filed: 1903-02-09
Granted: 1903-12-17
Abstract: 3042. Aspinall, F. B., and Dallas, J. D. Feb. 9. Electric railways and tramways on the conduit system. Conduits ; conductors.-Relates to a form of conduit designed to prevent it from becoming flooded and so short-circuiting the conductors. Fig. 2 shows a transverse sectional view of the conduit as used on tramways, and Fig. 3 as on railways. Fig. 1 is a longitudinal view of Fig. 2 with the collectors in position. The conductors b are suitably insulated and fixed in inverted troughs a, which are formed in sections. These troughs act like diving-bells, and thus prevent the water from rising in them when the conduit is flooded. The collectors extend below the sides of the trough and are provided with lateral arms which press brushes or rollers p against the underside of the conductors b. These collectors are guided from one section to the next by curved insulating- bridge-pieces i, all the current during this interval being taken temporarily from the other collector. The conduits are fitted at intervals with airtight boxes e, in which connections are made between the conductors b and feeders c, d. The weights u keep the rollers p pressed against the conductors b. The Provisional Specification also states that the current from the feeders to the conductor sections passes through cut-outs, so that in case of a short circuit the cut-outs open and the current then passes to the conductors through a resistance and fuse. If the short-circuit is still too large, the fuse blows and the corresponding section is cut out.
Patent GB-190303657-A (GB)
Title: Improvements in Regulating Devices for Electrically Propelled Vehicles.
Inventor: RAWORTH JOHN SMITH
Filed: 1903-02-16
Granted: 1904-02-11
Abstract: 3657. Raworth, J. S. Feb. 16. Electric m o t o r vehicles. - Relates to methods of controlling electricallypropelled vehicles. The regulating- lever has a fore- and-aft motion and governs the fieldmagnet excitation, and thus the speed of the motor. Another lever for controlling the armature current is connected to the controller casing and is limited in movement by a pin in the regulating - lever, in order that the armature circuit may not be closed until the field is at maximum strength. Fig. 2 shows the application to shuntwound motors. 268 The regulating-lever slides over the contacts g, h in the shunt circuit b of the motors a. The other lever controls a switch sliding on contacts t, u and so regulates the armature current. The switch moving over the contacts t, u may make contact between the blocks t, u<8> which are in circuit with series windings v<1>, and operate the automatic switch 15 which disconnects the armatures from the line. The motors thus provide an emergency brake. The electromagnetic 'switch 1, operated by the shunt field-circuit prevents this action while the field is excited by the shunt winding. The application of this regulating-device to motors with series windings as well as shunt windings is shown in Fig. 5. Here the lever attached to the regulating-lever operates a switch y, but only when the shunt field is very strong. This switch short-circuits the series windings v, which are so wound as to augment the fields when the motors act as generators.

Title: An Improved Method of Refining or Purifying Viscose.
Filed: 1903-09-30
Granted: 1903-11-05
Abstract: 21,030. Viscose Syndicate, and Cross, C. F. Sept. 30. Cellulose.-Consists in purifying and refining viscose solutions, which are obtained by the interaction of cellulose, alkaline hydrates, and carbon bisulphide as described in Specification No. 8700, A.D. 1892, by separating the cellulose xanthate therefrom. The cellulose derivative, either spontaneously on standing at ordinary temperatures, or by heating to about 50‹ C., becomes insoluble in solutions of sodium bicarbonate, which are added for the purpose of precipitating it. The precipitate is then washed with sodium bicarbonate alone, or in addition, sodium sulphite may be used for facilitating the removal of bye-products containing sulphur. Sodium chloride or sulphate solutions may also be used for preventing the rehydration of the derivative while under treatment. The derivative is then treated in a press or centrifugal machine for removing excess of solution, and strong caustic soda is added in sufficient quantity to redissolve the cellulose compound, thus yielding a purified viscose solution.

Title: Improvements in or connected with Corliss Valves.
Inventor: HARGREAVES FRANK
Filed: 1904-07-26
Granted: 1904-09-01
Abstract: 16,466. Hargreaves, F., and Hudson, J. G. July 26. Valves, distributing; stuffing-boxes, substitutes for. -A Corliss valve of the type in which a collar on the valve spindle bears against a bush on the valve bonnet is shown in Fig. 1. When there is a plenum in the cylinder, the collar C presses on the bush D, but, when there is a vacuum, the atmospheric air on the end of the spindle A tends to press the collar from its seat and thus allow leakage. To prevent this, a diaphragm H is arranged as shown, the pin M being adjustable. This diaphragm is larger than the end of the spindle, so that, when there is a vacuum in the cylinder, the collar is still held to the seat D and leakage thus prevented. This device is especially applicable to exhaust valves. A modification of this arrangement may be applied to relieve the pressure between the collar and bush. This is shown in Fig. 2. The plate H in this case is smaller than the end of the spindle A, so that, whether there is a plenum or vacuum in the cylinder, the pressure on the collar is relieved.
