Title: Improved Means for Effecting the Air-tight Closure of Jars and other Receptacles.
Inventor: BRUECKMANN FRANZ
Filed: 1898-02-09
Granted: 1898-03-12
Abstract: 3299. Br³ckmann, F. Feb. 9. Stoppers.-Relates to means for effecting the airtight closure of jars &c. from which the air is exhausted by boiling &c. The neck A and cover B are shaped so that when fitted together, as shown, they form a groove a, in which is inserted an elastic washer C of any desired sectional form. Before the fitting of the parts together, the washer is temporarily placed in the shallow groove E. To prevent displacement of the cover during boiling &c., it is held in position by the frame or yoke D. Two or more vessels may be placed one on top of the other and encircled by a single yoke. During boiling &c., the air &c. escapes past the washer C, and during cooling &c. the washer contracts inwardly and forms a tight joint. When desired, a washer of cork &c. may be interposed between the mouth rim of the vessel and the cover.
Patent GB-189814721-A (GB)
Title: Improvements in Compound Locomotive Engines.
Inventor: SMITH WALTER MACKERSIE
Filed: 1898-07-04
Granted: 1898-09-03
Abstract: 14,721. Smith, W. M. July 4. Compound engines.-Relates to improvements in compound locomotives of the kind described in Specification No. 20,769, A.D. 1890. Steam is admitted to the receiver by a reducing or pressureregulating valve so as to maintain automatically the pressure in the receiver at a predetermined amount, which can be increased at will when it is desired to increase the power of the engine. In order to enable such engines to start easily, each end of the high-pressure cylinder is connected to the receiver by a pipe or passage controlled by a non-return valve. Fig. 1 shows a transverse section through the smoke-box of a three-cylinder engine embodying the invention, with a single central high-pressure cylinder, and two outside low-pressure cylinders. The cylinders are constructed and arranged so that the one (or two) inside high-pressure cylinders 1 are secured to the main frames 15 independently of the outside cylinders 2, 3, and the receiver 4 is formed partly by the exhaust chamber of the highpressure and partly by the steam chests of the two low-pressure cylinders, so that connecting- pipes are dispensed with. A valve 1<b >for admitting steam and air is provided to destroy the vacuum in the high-pressure cylinder when running without steam. The non-return valves 7<a> and their connecting-passages 8<a>, 10<a> are disposed as shown, so as to be easy of access. An improved valve for admitting steam direct to the receiver is shown in Fig. 8. Boiler steam enters by the pipe 21, and passes to the receiver by the pipe 22 at a reduced pressure, owing to the throttling action of the valve 23. This valve tends to close under the action of steam pressing on the upper surface of the piston 25, which steam is admitted by a spring-closed valve 29. Means may be provided for altering the pressure of the spring on the latter valve, and thereby regulating the receiver pressure. The valve 23 is cushioned by liquid contained in the space 28, and by flexible washers 33. A valve 26 closes on a seat as shown, to prevent the escape of boiler steam when the valve 23 is closed. In order to avoid the use of rocking shafts and the like in the valve gears, the centre-lines of the inside cylinder and its piston valve are made to converge on the crank axle as described in Specification No. 22,868A, A.D. 1896, and the valve motion is disposed so that its centre line is towards one side, the valve spindle being connected to the motion by a crosshead.

Title: A Machine for Making Pasteboard Box Blanks.
Inventor: BINDER JOHANN
Filed: 1898-09-02
Granted: 1899-07-15
Abstract: 18,798. Binder, J. Sept. 2. Feeding sheets.-In making pasteboard boxes, the blank is carried by means of a reciprocating carriage K, Fig. 3, under the die or head F, Fig. 1, by which the blank is grooved transversely, then under a corresponding die, by which it is grooved longitudinally, and finally under the cutting-head, and is then ejected from the machine. The carriage consists of a frame having a series of spring grips k<4>, which grip the blank until it is carried past spring stops k<6> on the frame. The carriage is then reversed for a short distance, until the blank abuts against the stops, when the blank is in position to be operated upon. When the first grooving operation is completed, the carriage is reversed to its first position, and then in the next forward movement a fresh blank is fed, and the first blank is carried forward by the spring grips k<4> for the next operation, and so on.

Abstract: 12,658. Dobbie, J. C. June 17. Sounding-apparatus. -Relates to apparatus in which water is forced into a cylinder according to the depth of immersion, and consists in the provision of means for the escape of the air as the sounder is drawn up. The water passes in through a tube D and nipple E which is closed at the end but perforated with a ring of holes at E'. The holes are surrounded by a flexible sleeve F, which prevents the return of the water. These parts are fitted to the pivoted cap A'. A parachute valve may be substituted for the arrangement described. An air-vent tube B<1> facilitates the pouring out of the water when the instrument is brought on board.

Patent GB-190013664-A (GB)
Title: The Manufacture and Production of New Intermediate Products and of New Azo Colouring Matters therefrom, the use of these Dyes in Dyeing and their Treatment on the Fibre.
Inventor: JOHNSON JAMES YATE
Filed: 1900-07-30
Granted: 1901-01-05
Abstract: 13,664. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. July 30. Dyes, artificial.-Relates to the production of a new class of azo dyes which are characterized by possessing a sulphurous-acid phenolic ester group which renders the dyes more soluble in water than the corresponding dyes which do not contain this group. The sulphurous-acid group may be split off with production of the less soluble products, and, when this is effected after the dyeing operation, a high degree of fastness against milling and soap is developed in some cases. The sulphurous-acid group may be split off from the dyes when in solution by alkalies, acids, or a suitable oxidizing-agent, such as sodium-cupric glycerate, but after dyeing the best results are obtained by the use of cupric acetate, a further lake formation or other change being also produced by this reagent in some cases. The sulphurous acid esters employed are produced as described in Specification No. 1387, A.D. 1900. (1) Monoazo dyes are produced as follows :- The sulphurous acid ester of 1 : 8-amidonaphthol is diazotized and run into an alkaline solution of #-naphthol, whereby an orange-red wool dye is obtained. In a similar manner dyes may be obtained from m-phenylenediamine, resorcin, or 2 : 3- dihydroxynaphthalene instead of #-naphthol, and from the diazo compound of the sulphurous acid ester of 1 : 5-amidonaphthol or its sulphonic acid, or of 1 : 8-amidonaphthol-5-sulphonic acid, or of the product obtained by the action of sulphurous acid upon m-toluylenediamine, instead of the diazo compound of 1 : 8-ami donaphthol. A violetred dye is obtained by combining the diazo compound of the sulphurous ester of 1 :8 amidonaphthol with 1 : 8-amidonaphthol-4-sulphonic acid, or 1 : 4-naphthol sulphonic acid in alkaline solution. (2) Disazo dyes are produced as follows :-The diazo compound of the sulphurous acid ester of 1 : 8-amidonaphthol is combined with 1 :8-amidonaphthol-4-sulphonic acid, and the product is further combined with diazobenzene. The dye yields on wool a blue-black shade which is changed to a red-brown of greater fastness by subsequent treatment with copper acetate. Diazotized aniline is combined first with 1 :8-amidonaphthol-4- sulphonic acid in acid solution, and the product is combined with 1 : 8-amidonaphthol sulphurous acid ester in alkaline solution. This dye yields on wool a blue-black which is changed by copper acetate towards green. Diazotized 1:8-amidonaphtholsulphurous-ester-5-sulphonic acid is combined with alpha-naphthylamine, and the product is further diazotized and combined with 1 :4-naphthol sulphonic acid, whereby a violet wool dye is obtained, or with alpha-naphthylamine whereby a reddish-black wool dye is obtained.
