Patent GB-190404770-A (GB)
Title: Improvements in Automatic Regulators for Alternating Current Motors.
Filed: 1904-02-26
Granted: 1904-12-31
Abstract: 4770. British Thomson-Houston Co., [General Electric Co.]. Feb. 26. Motors, controlling.-Repulsion motors are controlled by automatically and gradually shifting the position of the brushes. In Fig. 1, the power circuit is represented by thick, and the control circuit by thin lines, and the ring B carrying the brushes b, b is connected by a chain, belt, or toothed gearing to an armature E carrying a weight W the torque of which for each position of the arm F balances the torque produced by the coils E, C. In the starting position, the arm F is held by a clip f, and contacts 7, 8 are bridged by the bar I, the brushes b, b being inclined at 90‹ to the line of magnetization; on closing the switch s, the current going to the earth G, through contacts 7, 8, energizes the coil A, and closes the contacts 3, 4 by the bridge a. The current then flows from T through the coil E to the ground, and also through the field coil S, coils C, and solenoid D, which then pulls back the clip and releases the lever F. The lever then falls, being balanced all the time by the torque of the coils C, E, till the stop f<1> is reached and the motor runs at full speed. To stop the motor, the switch s is opened, the bridge a falls, and the stator being no longer excited the motor comes to rest ; at the same time the current flowing through the coils c turns the armature E till the clip f catches the lever F and the coils are cut out. By changing the gear between the coil E and ring B, any acceleration may be produced, and, if desired, the relative connections between the coils C, c, and E may be varied. As several motors may be controlled by one switch s, the system is suitable for governing trains.

Title: Improvements in Elastic-fluid Turbines.
Filed: 1904-06-23
Granted: 1905-05-18
Abstract: 14,244. Warwick Machinery Co., [General Electric Co.]. June 23. Steam &c. turbines. - The efficiency of elasticfluid turbines is increased by decreasing the frictional losses due to the fan or blower-like action of the buckets and also to the friction between the wheel and the surrounding motive fluid. The base 1, Fig. 1, of the machine, which may be connected to a condenser or to the atmosphere, is surmounted by a casing 2 enclosing the second-stage wheel, upon which rests another casing 3 which encloses the first-stage wheel. Between the casings is a diaphragm 4, provided with nozzles for admitting the motive fluid to the second-stage wheel. The wheels 7 are provided with peripheral rows of buckets 8 and are secured together by bolts 9. Rings 10 divide the spaces between the wheels from the steam spaces. The casing supports nozzles 11, Fig. 6, containing preferably several passages or sections, each controlled by a separate valve actuated by some form of governor, but two or more sections may have a common valve. A frame 13 carries adjustable intermediate buckets 12 which cover an arc somewhat greater than that covered by the nozzles. Detachable plates 14, Fig. 2, are provided to allow of the clearances being observed. Smooth plates 15, 16, 17, 18, supported by the base 19, Fig. 1, are in close proximity to the idle buckets of the wheels. Cylindrical walls 20 extend wholly or partly around the wheels, and between these and the smooth plates are passages 21 through which water may escape. Attached to the plate 18 is a segmental plate 22 which prevents the formation of eddy currents in a radial direction, and the passages 23 fixed to the underside of this plate convey motive fluid from the centre of the wheel chamber to the passages 5. To regulate the passage of fluid from one wheel compartment to another, valves, operated by means external to the wheel casing, may be provided. In this particular case, flat slide valves operated by bandwheels on screwed rods are shown. A small valve is used for drawing-off water that has collected inside the casing.

Title: Improvements in Apparatus for Advertising, or Making Announcements, and the like.
Inventor: ADAMS FRANCIS HAMP
Filed: 1905-08-22
Granted: 1906-09-02
Abstract: 17,013. Adams, F. H. Aug. 22. Advertising; displaying. - Advertisements or the like are displayed on rotatable carriers behind openings preferably one e above and one below a clock, which controls clock-work or electric means for changing the advertisements and opening and closing shutters to expose and cover the advertisements periodically. The chiming of the clock each quarterhour is arranged to take place just t before or while the advertisements are exposed. In the apparatus shown, the axle of the minute-hand of the clock 5 carries a disk 17 with four pairs of pins 18 which in turn engage and depress a lever 19, thus through levers 20, 22 lifting a lever 23 so as to bring a pin 25 on that lever out of engagement with another pin 26 on the fly 28 of the spring motor 24. When this happens, the spring motor rotates the gear-wheels on the axes 29, 32, 27<*>; a cam on the axis 32, engaging a piece 35 on the lever 23, then keeps the lever 23 raised while the pinion 37 rotates a crank 38 through half a revolution, thus operating a rod 39 and, through a lever 40, rocking shaft 41, lever 43, and chain or the like 44, raising the shutter 12, and at the same time, through shaft 41, levers 45, 46, 47, rocking shaft 48, lever 49, and chain or the like 50, raising the shutter 13, thus displaying two advertisements on the plates 1 through openings 10, 11. During this time, the motor 24 has rotated the wheel 36 one-sixteenth of a revolution, thus bringing pins 51 nearly into engagement with levers 52, 53. The motor 24 is then stopped by the pin 25 on the lever 23 until the lever 19 is again operated, when the crank 31 is again given a half-revolution, thus allowing the shutters 12, 13 to fall by gravity. At the same time, the rotation of the wheel 36 causes one pin 51 to lift the end of the lever 52 free from a slot in a disk 55 and another pin 51 to engage the lever 53, which drives the disk 55 and therefore the carrier 3 by means of one of the pins on the disk, thus changing the advertisements on both carriers, the upper one 2 being connected with the lower one by cranks 8 and rods 9. Electric lights may be employed within the apparatus, and the current may be regulated by the motion of the shutters. The Provisional Specification states that folding doors or bands with openings alternating with solid parts may be used, that the doors or shutters may be normally held closed by springs or weights, and that the bands may receive from the clock mechanism a continuous or alternating motion ; also that the advertisements may be carried on endless bands passing over rollers, that the movements of the doors, shutters, or the like may be effected from the clock mechanism by any suitable means, such as mechanical gear, or electro-magnetic devices energized and de-energized by means of circuits made and broken by the clock-work at the requisite times.

Title: Improvements in Moulding Baths and other Large Articles in Sand
Inventor: DUPONT PAUL
Filed: 1905-11-29
Granted: 1906-06-07
Abstract: 24,746. Dupont, P. Nov. 29. Moulding.-Moulds for baths and other large articles are formed by apparatus and a process which are improvements on those described in Specifications No. 25,772, A.D. 1903, and No. 3Q4, A.D. 1904. Separate patterns formed from a master pattern are used for the formation of the two parts of the mould upon independent presses. The coniform compressors are modified in construction and shape and are retained in the moulds during casting, thus reducing the amount of sand required. The patterns are withdrawn and the mould parts assembled by aid of a carriage with a special stop. A sand mould is formed on a master pattern of the same thickness as the baths to be produced. The outer part is pricked all over the moulded surface and over part of the parting- surface by a shouldered needle to enable a layer to be removed with a trowel as indicated by the dotted line in Fig. 40. The mould is assembled and a casting taken. This casting is placed in a frame and supported externally by sand, and a paste which will solidify without shrinkage is filled into the interior and into a small flask placed above the flange formed at a, Fig. 40, on the casting. The resulting pattern E, Fig. 43, is covered by strip metal F of the thickness of the bath secured in place by bolts in holes d. The strip metal is cut from laminated sheets, and the edges are suitably profiled for uniting by soldering. In the case of sheet iron, autogenous soldering is employed. The casting is then fitted on a false flask, with its internal surface upwards, and the space underneath is filled with a solidified mixture. The coniform compressor l, Fig. 11, for the external mould is formed of sheet iron suitably stayed, carries removable flanged sheet-metal vent and gate formers g, h, and is held against the upper press beam K by suspension links k engaging a bar i. After compression, the bar is withdrawn and the compressor l descends with the pattern for'the removal of the formers g, h, which are replaced by wooden pieces for the completion of the gates by hand: The finished mould is raised and is held by its trunnions r and the links k against the beam K, and the platform and pattern are lowered away. The carriage J is located under the press by a square stop which can be turned out to contact with a column of the press. The internal mould, which has meanwhile been produced in another press, is brought underneath,' located by the stop, and raised for attachment to the other part. Loose patterns are used in forming the exterior mould part which remain in the sand after the removal of the main pattern and are then replaced by core pieces to form projections with bolt holes for the attachment of feet. The compressor for the interior mould part has a volume calculated as in the abovementioned Specifications, but is formed as a sharpedged prism. The method of fastening the flasks together and to the patterns is illustrated in the Specification.
