Granted: 1903-12-10
Abstract: 3182. Ransford, R. B., [Cassella & Co., L.]. Feb. 10. Acetyldiamidophenolsulphonic acid - Acetyl-pamidophenol is introduced at 40-90‹ C. into sulphuric acid of 66‹ BÚ., and heated for about two hours at 95‹ C. After cooling to 0‹ C., a mixture of sulphuric and nitric acids is added at from 0-5‹ C. After twelve hours, the nitrated mixture is diluted with ice-water, and, keeping the temperature below 30‹ C., sufficient zinc dust for complete reduction is slowly introduced. The difficultlysoluble monoacetyldiamidophenolsulphonic acid separates as colourless needles. The salts are easily soluble in water. Dyes, artificial.-Diazotization of the sodium salt of the foregoing sulphonic acid yields an easily-soluble yellow-coloured compound, which forms colouring-matters with phenols and amines. On mixing with #-naphthol and caustic soda at 0‹ C., with neutralization of the alkali after twelve hours, a dye is obtained which dyes wool in an acid bath a dull claret shade and, on being afterwards treated with chromate, is turned into an intense blue-black. The dye has excellent levelling properties. Similarly, dioxynaphthalenes, amidonaphthols and their sulphonic acids, give dark bluish shades.

Title: Improvements in Apparatus for the Reproduction and Amplification of Sound
Inventor: LAUDET GEORGES
Filed: 1903-07-10
Granted: 1904-07-07
Abstract: 15,294. Laudet, G. Dec. 6, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Sound-magnifying appliances: brass and like wind instruments.-Sonorous waves of any origin effect the expansion, combustion, and explosion of gases, vapours or liquids, in suitable chambers, thereby producing sound waves of the same pitch but increased amplitude, which may issue from resonators. For waves capable of such collection, a membrane A, Fig. 1, is employed, and its vibrations cause the expansion or explosion in the chamber D of gases, liquids, or vapours, such as hydrogen, acetylene, coal gas, ether, petrol, alcohol, or the like, which enter by the pipe B and fill the chamber C. The roughened sides of the chamber D increase the effect, and there may also be single or multiple resonators above this chamber. A metallic gauze screen, Fig. 3, may be arranged between the parts E, F to check the violence of the expansions or explosions, and there may also be a valve S with rod attached to the centre of the membrane for impeding the passage of the fluids into the chamber D. A second pipe K permits the introduction of a second fluid which has already had sonorous vibrations imparted to it, which may be harmonics of the note received by A, so as to produce a resultant compound wave. Where the sound-producing body to which the apparatus is to be applied has a vibrating surface or membrane, the membrane A may be dispensed with, and this is the case when applied to telephones, phonographs, reed instruments, and the like.

Title: Improvements in Automatic Weft-replenishing Looms.
Inventor: WALKER ALBERT EDWARD
Filed: 1904-06-29
Granted: 1905-06-01
Abstract: 14,630. Walker, A. E., Walker, A., and Walker, G. June 29. Loom shuttle-changing mechanism; shuttle boxes; swells.-Consists of improvements in the shuttlechanging mechanism of the rotary-box type described in Specifications No. 16,156, A. U. 1901, and No. 15,234, A.D. 1902. A ledge 230, Fig. 5, is formed on the front wall 231 of each compartment of the shuttle box. When a compartment is in the upper or weaving position, the ledge retains the shuttle therein and acts as a screed, and, when the compartment is in the front or receiving position, it acts as a shuttle-retaining ledge. When a full shuttle is presented for delivery into the front compartment of the box, the edge of the shuttle presses against the lower edge of an incline 233 formed on the swell 40, so that the swell is raised to allow the shuttle to enter the box. Instead of or in conjunction with this arrangement, the headpiece 6 of the shuttle feeder may have fixed upon it a projecting piece 237, which acts upon an inclined piece 238 on the swell to raise the latter. The shuttle passes over the ledge 230 and falls below it. The spring fingers 19 in the shuttle feeder are made capable of self-adjustment to the level of the edge of the front wall of the shuttle box, by carrying them through elongated holes in the front of the feeder, and providing each finger with a spring-controlled saddle which embraces its upper surface but permits a vertically-yielding movement. The ends of the fingers 19 are shaped to fit recesses 240 formed on the edge of the front wall of each compartment of the shuttle box, the recesses being curved outwardly on their lower edge to raise or position the fingers 19. When the shuttle box has only two compartments, the used shuttle is discharged from the rear compartment, and the auxiliary spring acting upon the swell, as described in Specification No. 16,156, A D. 1901, is dispensed with. In a four-compartment shuttle box, the auxiliary spring may be employed to retain the shuttle until it is in the bottom compartment. In adapting the shuttle-feeding device to a lay carried by two swords at each end, Fig. 11, a construction which maintains the lay in parallel planes, the feeder 6 is pivoted at 245 in such a manner that the fingers 19 pass into the feeding position in the arc described by the edge of the front wall 231 of the receiving-compartment, and the fingers are placed in the feeder so that they retire on the chord x y of the arc. The arms 6<a> of the feeder are curved outwardly at 6<b> to the right and left to permit a used shuttle, when leaving the lay, to pass between them to a receptacle carried by the feeder or fixed to the loom frame. The shuttle-changing mechanism may be used in conjunction with a rotary or drop box at the other end of the lay. In the Provisional Specification, it is stated that leather bands are riveted to the receiving-shoot under the shuttle box and the receptacle under the feeder, to receive the discharged shuttles lightly and noiselessly.
