Title: A New Method of Producing Occulting Lights for Lighthouses, Beacons, Buoys, and other Lights.
Inventor: WIGHAM JOHN RICHARDSON
Filed: 1898-03-10
Granted: 1899-02-18
Abstract: 5841. Wigham, J. R. March 10. Revolving lamps or lanterns.-Relates to lamps or lanterns for lighthouses, beacons, buoys, or other lights in which the frame carrying the occluding or coloured screens is revolved by the escape of the heated products of combustion or hot air without the aid of fans or louvres. The revolving frame K carrying the occluding or coloured screens N is mounted upon a steel pivot P, and is provided with a number of curved tubes T. The products of combustion or the hot air escaping from these tubes cause the frame K to revolve. The usual chimney is supplemented by a conical flue C to deflect the ascending gases towards the lower ends of the tubes T.

Patent GB-189907979-A (GB)
Title: Improvements relating to Methods of and Means for Regulating Electric Motors.
Inventor: LUNDELL ROBERT
Filed: 1899-04-15
Granted: 1899-07-29
Abstract: 7979. Lundell, R. March 3, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Motors, controlling.-Relates to the regulation of one or more electric motors on the series-parallel principle. Each motor is provided with two arma. ture windings, connected to separate commutators, and with a compound wound field magnet. By means of suitably-arranged resistances, the fieldmagnet strength is changed from a strong shunt and weak series for the lower speed combinations to a weak shunt and strong series for the higher speed combinations. These changes are effected by a controller of the ordinary type. Fig. 4 shows the various combinations of the motor circuits as the controller cylinder is rotated in passing from the lower to the higher speed. The motor is supposed to be used in connection with a divided storage battery for the propulsion of electric vehicles and similar uses. In the first or low-speed position, the two commutators C' and C' are in series and the batteries in parallel ; the resistances R, R<1> in series with the shunt winding 0 are short-circuited, and the series winding T is shunted through a low resistance R<3>. In the second position, the shunt field is weakened by the resistance R and the motor speed is increased. In the third position, the batteries are changed from parallel to series, and the shunt field is raised to its maximum strength, while more current is caused to pass through the series field coil by introducing a second resistance R<2> in series with R<3>; under these conditions, the motor speed is again increased. In the fourth position, the shunt field is weakened, and a further increase of speed follows. In the fifth position, the armature circuits are changed from series to parallel, and a strong current is sent through the series field windings, the shunt field having only a moderate excitation. Finally, in the sixth position, the motor is practically converted into a series motor. Two motors of this description may be employed in combination.

Title: Improvements in Hydraulic Presses, particularly adapted for Extracting Oil from Oleaginous Seeds.
Inventor: EUSTON ALEXANDER
Filed: 1899-08-22
Granted: 1899-09-30
Abstract: 17,013. Euston, A. Aug. 22. F a t t y oils, extracting. Relates to hydraulic presses particularly adapted for the extraction of oil from oleaginous seeds. Fig. 3 shows a horizontal section of the press. Each plate F is provided with lugs f which embrace guide-rods G, and has ribs f<1> along its side and front edges. The back is open to allow the escape of the expressed oil. Corrugated panels F<1> are made in the surface of each plate. Each plate is supported by four rotatable supports H, mounted on the columns A, provided with projections h which may be turned simultaneously to support or release the plate, by means of the handles j. Fig. 7 shows a support consisting of a slide M, which is operated by the movement of the bent rod N. Another modification is described in which the plate is supported on bellcrank levers pivoted to collars on the columns. By any of these arrangements the plates may be supported, when the ram has reached its highest point, and may be released one at a time for the removal of the pressed cakes as the ram descends. A modification is described in which the plates are automatically released, one at a time, as the ram descends, by means of a dog operated by rack- and-pinion mechanism, which actuates the rods connected to the plate supports.

Title: Improvements in and relating to Rove Stop Mechanism for Spinning Machines.

Granted: 1900-07-28
Abstract: 3234. Fraser, J., Fraser, J. G., and Walker, H. Feb. 19. Stop-motions; delivery, stopping.- When the rove R breaks, the eye a', through which it passes to the retaining rollers, is moved sideways so as to cause the rove to pass from between the rollers c, d, and simultaneously that part of the rove which has already passed the retaining - rollers is held by heckle pins l. The eye a<1> is formed on a lever a, which is pivoted at b<1>, is weighted or actuated by a spring, and is normally held in the position shown by the upper end of a rod f, which is connected with the detector lever h. This lever also carries the heckle pins l. During the time that the parts are being re-set in their working position, the rod f is held up by the end of a spring f<4> which engages with a projecting stud e. Three modifications are described. In two of these, the tumbling lever is fitted behind the retaining-rollers, and in the third between them. Two of these modifications also involve the motion of the detector lever h sideways, instead of in a vertical plane.

Title: The Manufacture or Production of New Coloring-matters of the Acridine Series.
Inventor: NEWTON HENRY EDWARD
Filed: 1900-06-18
Granted: 1901-05-04
Abstract: 11,035. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. June 18. Alkyluted tetramidodiphenylmethanes dyes, artificial.-Relates to the formation of asymmetricallyalkylated diamidoacridines representing yellow dye-stuffs for leather. The bases used are either di- or tri-alkylated tetra-amidodiphenylmethane or its homologues, obtained from formaldehyde, an asymmetrically-dialkylated m-diamine, and a non- or mono-alkylated m-diamine ; or corresponding nitrated and reduced alkylated diamidodiphenylmethane derivatives. In an example, a solution of dimethyldiamidophenyl-o-tolylmethane in sulphuric acid is slowly mixed in the cold with a mixture of nitric and sulphuric acid, and the dinitro compound formed is precipitated in icewater, neutralizing with sodium carbonate. The product is recrystallized from acetone, dissolved in hydrochloric acid, and reduced in the cold with zinc dust. This product is filtered and precipitated with caustic-soda lye, and can be further purified by recrystallization from a chloroform solution. The salts of the bases obtained are transformed into acridine derivatives on boiling with water, either in open vessels or in an autoclave under pressure. This reaction is accelerated by the presence of mineral acids, zinc chloride, &c. The oxidation of the resulting acridine leuco bases, to form corresponding colouring-matters, begins on exposure to air, and is accelerated by the use of ferric chloride &c. As an example, a solution of dimethyltetra-amidophenyl - o - tolylmethane in sulphuric acid is boiled in a lead-lined vessel, cooled, and mixed with calcined sodium carbonate sufficient partially to neutralize the acid, and also sodium, zinc, and ferric chlorides, when the dyestuff is precipitated as a reddish-brown resinous mass, which soon solidifies to a red crystalline mass giving an orange-yellow solution in water.

Water-tube boilers.-The front header is divided into a middle and two lateral portions, the partitions rising into the steam drum. Either the middle or the lateral divisions may serve for downflow. The tubes are divided by partitions in the heating-chamber, into corresponding groups. Water enters the steam drum through the pipe M, which extends to the rear. It flows forwards beneath an arched and perforated partition G<1> and, in the arrangement shown, descends into the lateral divisions of the front header. Thence it passes through the lateral group of tubes to the rear header, which is freely mounted to allow for expansion, and returns through the central group of tubes to the central division of the front header.
