Title: Locking Bolt.
Inventor: DAELMANS HENRI
Filed: 1897-11-11
Granted: 1898-01-01
Abstract: 26,275. Daelmans, H. Nov. 11. Sliding bolts.-A bolt A, sliding in guides E, can be locked by a hasp plate B engaging in a lock D on the plate F. The bolt may be locked in the shot or retracted positions, rendering the fastening reversible either as a lock or fastening.

Title: The Manufacture of p. monoalkylamido p. oxydiphenylamines and Dyestuffs therefrom.
Inventor: RANSFORD ROBERT BOLTON
Filed: 1901-04-17
Granted: 1902-02-27
Abstract: 7919. Ransford, R. B., [Cassella & Co., L.]. April 17. Monoalkyl-p-amido-p-oxydiphenylamines are produced either by reducing the products obtained by a joint oxidation of monoalkyl-p-phenylenediamine and phenol, cresol, o-chlorophenol, or salicylic acid, or preferably by oxidizing monethylaniline, for example, with p-amidophenol by means of sulphuric acid and potassium bichromate, and then reducing the products by adding sodium sulphide to the mixture. Monometbyl- and monoethyl-p-amido-poxydiphenylamine form colourless crystals, which melt respectively at 171‹ C. and 130' C. Dyes, artificial, which dye unmordanted cotton reddish-blue, pure blue, and greenish-blue shades, are produced by heating the foregoing monoalkylated - p - amido - p - oxydiphenylamines with sodium sulphide and sulphur at 115‹-120‹ C. for six to ten hours. The melt is best desiccated in vacuo, and the crude product may be used as it is. For obtaining the pure dye, the melt is dissolved in water containing common salt or calcium chloride whereby the dye is precipitated. Alternatively, the melt is neutralized by an acid, the raw leuco compound which is precipitated is separated from inorganic salts, and dissolved in diluted hydrochloric acid, and the leuco compound is then salted out, or the dye is precipitated by oxidizing-agents.

Granted: 1902-01-23
Abstract: 10,412. Akt.-Ges. fiir Zink-Industrie vorm. Wilhelm Grillo and Schroeder, M. May 20. Catalysis; sulphuric anhydride.-Porous contact substances for use in catalytic processes, such as in the manufacture of sulphuric anhydride, are prepared from liquid, pasty, or like substances or from crystals which dissolve in their water of crystallization, by forcing or drawing a gas through the material, so that, during evaporation, a number of pores, blow-holes, or passages are formed in the body. A suitable apparatus is shown, in which a rotary blower a forces air through tubes c in a furnace d, and thence through a tube e having a thermometer f to the lower part of a vessel g having compartments i<1>, i<2>, i<3>, each compartment having a perforated bottom h<1>, h<2>, h<3>. One perforated bottom h<1> is first put into place, and a thin layer of some suitable material, such as the dry salt employed, placed thereon. The contact material, such as magnesium sulphate, clay, loan, gypsum, or asbestos powder, mixed or sprinkled with a platinum-salt solution, is then gradually added, until, in consequence of the air, heated to about 200‹-300‹ C., passing through, a thick layer of porous material is finally obtained. The second and third layers, or as many more as are required, are then similarly prepared, one at a time. The cover and an exit tube k are then put in place, and the material and apparatus are ready for use in catalysis. Reference is made to Specification No. 25,158, A.D. 1898.
