Title: Improvements in the Manufacture of 1.8-amido-naphthol-4-sulphoacid and of Intermediate Products relating thereto.
Inventor: WILLCOX Benjamin
Filed: 1900-09-22
Granted: 1901-07-20
Abstract: 16,921. Willcox, B., [Badische Anilin & Soda Fabrik]. Sept. 22. 1 : 8-Amidonaphthol-4-sulphonic acid and its sulphurous-acid ester are produced as follows :-1 : 8- Naphthylenediamine is dissolved in soda solution and heated with sodium bisulphite in the presence of acetone, or a similar body, first to 60‹ or 65‹ C., whereby a condensation of acetone, or of its bisulphite compound, with the diamine is effected, and the intensely-yellow solution thus produced is then further heated at 95‹ or 100‹ C. for two or three days. After acidifying the product and boiling off the sulphurous acid, a solution is obtained which probably contains the very soluble sulphurous-acid ester of 1 :8-amidonaphthol-4- sulphonic acid. On addition of an alkali, or other saponifying-agent, even at low temperatures, the ester is decomposed, and on acidifying the solution a crystalline precipitate of the 1 : 8-amidonaphthol- 4-sulphonic acid is obtained. The process may be modified by first separately condensing the diamido acid with acetone, and then acting upon the product with bisulphite.

Title: Improvements in Refrigerating Machines.
Inventor: WINDHAUSEN FRANZ
Filed: 1901-02-08
Granted: 1902-02-06
Abstract: 2742. Windhausen, F., and Windhausen, F. Feb. 8. Vapour engines.-In compression refrigerating- machinery using ammonia, sulphurous acid, carbonic acid, &c. as the working medium, the compressor is actuated partly or wholly by a vapour engine, coupled directly or indirectly, and worked by the same working liquid. As shown in Fig. 1, the compressor B, evaporator or refrigerator C, and cooler or condenser A are on the left while the parts on the right include a separate vapour engine F, generator E,and. condenser G,with a pump H to transfer the medium from the condenser to the generator. A single condenser may serve both parts of the apparatus, in which case the pump transfers part of the condensed ammonia &c. to the high tension generator. A steam engine may be used, if required, to supplement the power from the vapour motor and its exhaust steam utilized partly nr wholly for the vapour motor. Live steam or other supply of heat in addition to exhaust steam may be used for heating the generator and the vapours therefrom may be passed through a superheater. Diagrams of these arrangements are given in the Specification. The vapour engine and compressor may be combined instead of being coupled or geared and two of the several combined forms are shown in Figs. 5 and 7. In these one end of the cylinder acts as a motor and the other as the compressor and the expanded gas from the motor end is transferred to the compressor end by a valve on the cylinder or the piston. In Fig. 5, the distributing-valve is of the piston type with two pistons c, d, but the arrangement may be modified for one piston. A relief valve g is placed on the compressor. In Fig. 7, the main piston-rod carries two pistons to isolate the ends as regards heat transmission. The connection between the ends is made by a spring valve s in the piston which opens when the piston reaches the pressure-equalizing passages p<3>. It may, however, be made by a valve similar to the admission valve r, which is opened when struck by the piston and closed by its spring when the pressure is equalized through the passage r<7>. A valve r<6> regulates the equalization and determines the speed. The valves c, d serve as inlet and outlet at the compressor end.

On the index board 2 forming the front of the casing, the candidates' names read vertically to the designations of the organized parties and horizontally to the vacant offices, and the board is scored by corresponding horizontal slots 5 and a terminal vertical slot 6 connecting them. To each candidate is allotted a counter 12,which is mounted in a hinged cradle 17 having a cam slot 22 through its front plate 21, so that, if a slide 10 movable along a horizontal slot 5 is left in the middle of the cam slot, the counter will be shifted from engagement with a fixed locking-peg 20 to engagement with a vertical rack 27. The racks are rigidly connected by a bottom bar 33 and a top bar, and are normally suspended by a latch 26. When the voter has set all the slides as he desires, he lets the racks drop by lifting a frame 29 (which can only move if the handles are set central) against the latch 26. Thus one is added on all the counters in gear with the racks. On opening the door of the polling stall, a bevelled slide 32 linked to it lifts the racks again and a vertical bar is drawn across the index board to return the handles to the departing side of the casing.
