Abstract: 8767. Dieffenbach, O., and Moldenhauer, W. April 22, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Void. [Published under Patents &c. Act, 1907.] Hydrocyanic acid is produced by passing over highly heated carbon a mixture of hydrogen and nitrogen with carbon monoxide and dioxide. The proportion of hydrogen present is preferably increased, if Dowson gas be used so as to be more nearly equal to the quantity of nitrogen present. The formation of the gas mixture and its subsequent action on the carbon may be conducted in the same apparatus, by passing a mixture of air and water vapour over highly heated carbon. Electric heating is preferable, and, if the electric arc be employed, the electrodes themselves may furnish the necessary carbon. The hydrocyanic acid may be passed into sulphuric acid to form ammonium sulphate.

Filed: 1908-07-21
Granted: 1909-04-29
Abstract: 15,463. Soc. pour l'Industrie Chimique Ó Bale. July 22, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Samples furnished under Section 2 of Patents &c. Act, 1907. p - Aminophenyl - 2 - azimido - naphthalene - and naphthol sulphonic acids.-2 : 5 :7-naphthylamine disulphonic acid is condensed with 2 : 4-dinitro- 1-chlorbenzene, and the resulting dinitro compound is partially reduced to form the p-nitro-o-aminophenyl-2-naphthylamine sulphonic acid, which is then converted into the azimido compound by treatment with nitrous acid, the nitro group being finally reduced ; fusion with caustic soda gives the corresponding naphthol derivative. The Specification in the original form, as open to inspection under Section 91 (3) (a), describes also the production of similar azimido derivatives from 2:1 :5:7- and 2:3:5:7-naphthylamine trisulphonic acids; this subject-matter does not appear in the Complete Specification as accepted. Dyes, artificial.-Azo dyes dyeing cotton various shades of red are obtained by combining p-aminophenyl-2-azimido-5-naphthol-7-aulphonic acid with diazo or tetrazo compounds. According to examples, diazo-m-xylene, diazobenzene, o-diazotoluene, pdiazotoluene, #-diazonaphthalene, p-diazoacetanilide, and the tetrazo compounds from m-azoxyaniline, m-azoxytoluidine, azoxyanisidine, benzidine, and its homologues are used. Mixed disazo dyes are obtained by combining one molecular proportion of a tetrazo compound in any order with one molecular proportion of the azimido body and one molecular proportion of one of the usual components. According to an example, m-azoxyaniline is tetrazotized and combined first with 2:5:1:7- aminonaphthol disulphonic acid and then with the azimido body ; naphthol sulphonic acids, aminonaphthol sulpbonic acids or acidylaminonaphthol sulphonic acids may also be used. The monoazo and disazo dyes described above may be diazotized in substance or on the fibre and combined with any of the usual components. According to au example, the monoazo dye from diazo-m-xylene is diazotized and combined with 1 : 4-naphthol sulphonic acid ; a- or #-naphthol mono- or poly-sulphonic acids, chlornaphthol sulphonic acids, amino- and acidylaminonaphthol sulphonic acids may also be used. Or the azimido body may be diazotized and combined with a suitable component and the monoazo dye thus produced may be combined with a diazo compound. The dyeings from the above-described monoazo and disazo dyes diazotized and developed with #-naphthol yield various shades of red. The azimido body may be diazotized and combined with itself giving a bordeaux-red dye. The Specification in the original form, as open to inspection under Section 91 (3) (a), describes also the use of the azimido naphthol derivatives from 2 : 1 : 5 : 7- and 2 : 3 : 5 : 7- naphthylamine trisulphonic acids in the above processes ; this subject-matter does not appear in the Complete Specification as accepted.

Title: Improvements in Wireless Signaling.
Inventor: FESSENDEN REGINALD AUBREY
Filed: 1908-11-24
Granted: 1909-11-24
Abstract: 25,305. Fessenden, R. A. Dec. 23, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Wireless signalling; switches.-In a system of wireless signalling using undamped waves, a rapidly rotating commutator 20, 21 is arranged to shortcircuit periodically parts of an inductance 19 in the main oscillating circuit, so that cycles of waves having frequencies of; say, 100,000 ; 100,100 ; and 100,200 are continuously emitted and are received by a heterodyne receiver 45, through the coil 46 of which flow currents of the same frequencies produced locally at the receiving station by a commutator rotating synchronously with that at the transmitting-station. Signals are given by interrupting the short-circuits of the parts of the inductance 19 by means of electro - magnetic switches 38, 39 controlled by the sending-keys 40, 41. The depression of the key 41 results in the transmission of cycles of waves having frequencies of 100,000, 100,000 and 100,200, which interfere with the local currents in the receiver and produce beats having a frequency of 100, which note is taken to represent a " dot." In the same way, the depression of the key 40 causes the emission of waves having frequencies of 100,000 ; 100,000 and 100,000, which produce beats having a frequency of 200, this note representing a" dash." The commutator-shaft 20<a> is rotated by a motor 22, the speed of which is regulated by a tuning- fork 25 as described in Specification No. 26,552, A.D. 1902. If the commutators at the transmitting and receiving stations are not in phase, musical chords are produced in the receiver 45, and the commutator brushes 26, 27, carried by a gearwheel 29, are adjusted, until a minimum sound is heard, by means of the keys 30, 31, which actuate a clutch mechanism 34 and bring a disk on a threaded-shaft 34<a> into contact with one of the rotation friction disks 34<c>. The electro-magnetic switch 43, Fig. 1, connecting the antenna to the transmitting or receiving systems, is controlled by a switch 50. Fig. 2 shows the arrangement for duplex working. The oscillating circuit containing the capacity 18 and inductance 19 includes also the primaries of four transformers, the secondaries of which are in series with the fixed coil 64 of the receiver and the primary of the oscillation-transformer 65. The coil 44 is connected through inductance and capacity to the middle points of the latter circuit as shown.

Title: Improvements in and relating to the Continuous Dyeing of Skeins.
Inventor: REGORDOSA JUAN
IPC: D06B3/08
Filed: 1909-04-20
Granted: 1910-03-10
Abstract: 9307. Regordosa, J., and Regordosa, L. April 20. Hank type.-In a machine for dyeing skeins, wherein these are carried on frames fixed to endless parallel chains, cords, or belts, the row of skeins is agitated as it enters the bath, at a point near the surface thereof. The circulating and agitating apparatus referred to is carried by a framework F, mounted on wheels p, which run on rails r, so that the whole can be run from over one vat f to over any other f<1>, the frame h, which carries the immersing-rollers d, d<1>, d<2>, being raised clear of the vat walls; weighted rollers u, on the same axis u<1>, which moves in a vertical slot v, rest on the top part of the chains c, allowing them to yield to the oscillations imparted to the chains, and taking up the slack caused by raising the frame h. Several means of producing the agitation of the supporting - belts c, carrying the skeins a on frames b held by carriers e, are described, as follows. (1) To-and-fro movement perpendicular to the plane of the chains c. A roller z, with larger end-disks z' opposite the chains e, is hung by arms g<2> on a shaft g<1> outside the chains c, in conjunction or not with a second roller x slung on arms x<2> behind the chains c. The second pair of arms x<2> are connected by rods x<1> to the first pair g<2>, and the shaft g<1> is oscillated by a rotating disk k through an eccentric pin, an arm kl, and a lever. (2) Horizontal to- and-fro movement perpendicular to the direction of the last movement. The reciprocal motion from the disk k is passed through a bellcrank lever to a horizontal and longitudinally movable rod provided with forks which embrace the chains c. (3) Semicircular movement. The rollers z, x are replaced by bars 7, 4, Fig. 5, of which one carries a roller 8 opposite one chain c, and the other a roller opposite the other chain c. The carrying-arms 3, 6 are connected by a rod 2 pivoted so that, when one roller 8 pushes the corresponding chain c in one direction, the other roller pushes the other chain in the opposite direction. An alternative method of obtaining a semicircular movement is described. As the skeins leave the liquid, they pass between draining-rollers i and loose circular brushes j, which oscillate longitudinally and oppositely under the action of the rotating disk k, acting through a rod l and a double bellcrank lever. One of the lower immersing-rollers d also receives a longitudinal oscillation from the shaft of one of the brushes j through a suitably fulcrumed lever.
