Title: Improvements in or relating to the Electrical Igniters of Gas and similar Explosive Vapour Motors.
Inventor: BELLAMY ALFRED ROWE
Filed: 1902-05-15
Granted: 1903-04-09
Abstract: 11,139. Bellamy, A. R. May 15. Gas and explosive -vapour engines, starting in. During normal running, the electric generator for igniting is worked by the cam i raising and suddenly releasing the lever j connected to the armature. To prevent premature ignition at starting, the ignition is retarded by sliding a lever a into the path of an arm m on the lever j, which prevents the rapid return of the lever j until the arm a is moved by the cam d. The first explosion is produced by moving the lever a by hand, and, after the engine is fairly started, the lever a is slid out of the paths of the arm m and cam d, and retained by the pin b<1>.

Patent GB-190303768-A (GB)
Title: Improvements in Processes of Making Pigments.
Inventor: ARMBRUSTER WILLIAM JOSEPH
Filed: 1903-02-17
Granted: 1903-06-04
Abstract: 3768. Armbruster, W. J., and Morton, J. Feb. 17. Pigments.-A pigment, consisting of an intimate mixture of precipitated zinc hydrate and barium sulphate, is prepared by successively precipitating the zinc hydrate and barium sulphate from solutions of zinc sulphate and soluble barium salts. As an example, one molecular proportion of an aqueous solution of zinc sulphate is mixed with two molecular proportions of sodium hydrate. To the solution, when drained from the precipitate, one molecular proportion of barium sulphide is added. After separating the sodium sulphide from the second precipitate, the two precipitates are ultimately mixed together, and the mixture is washed and drained or filter-pressed. The mixture may be calcined so as to convert the zinc hydrate into zinc oxide. Instead of barium sulphide, other salts of barium may be used, such as the chloride, acetate, or nitrate. The proportion of barium sulphate in the mixture may be increased by adding sodium sulphate to the solution after the first precipitation, and correspondingly increasing the quantity of barium salt added. The sodium sulphate used must first be purified from any sulphate of iron which it may contain by the addition of either sodium sulphide or the hydrate of an alkaline earth or alkali metal. On the other hand, the proportion of zinc hydrate may be increased by adding zinc chloride to the original solution. Where barium salts other than the sulphide are used, it is not necessary to separate the solution from the precipitate after the first precipitation.

Granted: 1903-06-25
Abstract: 5950. Gally, R. A. March 14. Music notation.-Relates to music records, diagrams, patterns, and the like, and has for object the recording and illustrating of musical compositions as regards their rhythm, dynamics, part distinctions, and phrasing. Fig. 1 shows a portion of a record, diagram, or pattern, illustrating the forms of marks to indicate the notes. In Fig. 3, the measures, beats and sub-divisions, and cumparison of attack are indicated by the usual transverse lines, and the details of dynamics &c. are shown by lines 17 .... 28, at angles or slants. The angles correspond in degree to the ratio of speed of the recording key to the speed of the paper, a quick attack with strong touch approaching a right-angle. The notes may be marked by the writer instead of by a mechanism controlled by a musical instrument or key. Music sheets, patterns, and records have the notes marked at the sides of the holes to be punched, and the marks remain after the holes are cut, allowing verification.

Abstract: 20,639. Lehmann, E. Sept. 25. Motor road vehicles.-In connection with mechanism for transmitting motion between shafts, means are provided for equalizing the effort transmitted to the driven shafts. Figs. 1 and 2 show the mechanism as applied in transmitting motion from a motor shaft to the driving-wheels of a motor road vehicle.

Patent GB-190328051-A (GB)
Title: Improvement in Synchronising Apparatus for Dynamo-electric Machines.
Inventor: LINCOLN PAUL MARTYN
Filed: 1903-12-21
Granted: 1904-05-05
Abstract: 28,051. Lincoln, P. M. Dec. 29, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Dynamos and motors, synchronizing.-Relates to means for securing synchronism of alternating- current electric machines, especially adapted to the case in which two mechanically-connected machines, such as the parts of a motor-generator, adapted for currents of different frequency, are to be con-- nected in parallel to similar pairs of machines. In such a case it is desirable to run the unconnected machines up to such a speed, before connecting them to the circuits, that, when connected, they are in synchronism with those previously connected. Fig. 1 shows two motor-generators 3, 4, each consisting of a pair of machines 5, 6 adapted to be connected to circuits 1, 2 conveying currents of different frequency suitable for the machines 5, 6. The synchronism indicator consists of two instruments 9, 10 of any ordinary and suitable construction, adapted to actuate two pointers 20, 19 placed one in front of the other in front of a dial 21. The instruments 9, 10 may each consist of a laminated core 11 with a field coil 12, and of an armature wound with two coils 14, 15 placed at right-angles to each other and connected by sliprings 16 to the external circuits. The shaft carrying the pointer 19 and one of the armatures projects through the hollow shaft carrying the other pointer 20 and armature. The potential at which energy is supplied from the circuits 1, 2 to the field coils 12 and from the machines 5, 6 to the armature coils of the instruments 9, 10 is reduced, if necessary, by means of transformers 24, 25. When dealing with single-phase currents, as in the apparatus shown, phase-displacing devices, such as adjustable resistances 23 and inductances 22, must be provided to secure a displacement in phase of about 90‹ in the currents through the coils 14, 15. In the operation of the apparatus for starting, for example, the machines 5, 6 of the motor-generator 4, the corresponding switches 26, 27 are closed, and the pointers 19, 20 observed until they simultaneously indicate synchronism, when the switches 28, 29 may be closed. Otherwise the motor 6 may be connected up to the circuit 2, started, and brought to synchronism by any suitable means. The field of the machine 5 is then excited, and the armatures of both machines connected to the synchronizing-indicator. The switch 28 is then opened, and the motor allowed to slow down until the pointers 19, 20 indicate that the machines are running in proper phase relation, when both switches 28, 29 may be closed. Other methods of manipulating the machines and indicator may also be employed.
