Abstract: 3455. Canellopoulos, J. M. Feb. 13. Gas valves and cocks; diaphragm valves.-To allow of public and other lamps fitted with automatic igniting devices, of the kind described in Specification No. 17,791, A.D. 1902, being lit and extinguished from a distance by varying the pressure of the gas in the mains, each burner is provided with a diaphragm valve a, which may be adjusted by means of a spring k and a nut l. When the gas pressure in the mains is within the limits for which the burner is adjusted, the gas traverses the pipe m, the passages s, t, c, d and the tubular valve f to the chamber q, whence it passesby the channels g, h to the burner. Upon increasing the pressure of the gas in the mains sufficiently to overcome the combined pressure of the spring k and of the air entering through the apertures v, y, the diaphragm a is raised, and, forcing the end of the tubular valve f upon its seating e, cuts off the supply of gas and extinguishes the burner.

Patent GB-190307353-A (GB)
Title: Manufacture of Green Dyestuffs of the Anthraquinone Series.
Inventor: IMRAY OLIVER
Filed: 1903-03-30
Granted: 1904-02-11
Abstract: 7353. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. March 30. Dyes, artificial.-The 1 :4 : 5 : 8-leuco-alpha-tetra-oxyanthraquinone (obtained by nitrating anthrarufin or chrysazin or the ethers thereof, and reducing the dinitro-alpha-dioxyanthraquinones or their ethers obtained), is heated with aromatic amines, producing dialphylamidodioxyanthraquinones as condensation products. These are easily sulphonated, the sulphonic acids yielding difficultly-soluble alkalineearth salts. The dyeings are clear yellow-green shades, and the aqueous solution of the sulphonic acids of the dye-stuffs is yellow-green, which by adding caustic alkali turns blue. Examples :-(1) The leuco body is heated with aniline hydrochloride and aniline for several hours at 100‹-120‹ C. while stirring. The product is filtered, and the residue washed and dried, forming dianilidodioxyanthraquinone, which crystallizes from hot benzene in brassy needles, and dissolves in concentrated sulphuric acid to a pure green. The base is sulphonated by heating with sulphuric acid, and the dye-stuff precipitated with salt as a dark-green crystalline powder. The acid potassium salt crystallizes as black needles. The dyestuff dyes wool in an acid bath a pure green tint, and chromium-mordanted wool a more yellowish tint. Sulphonation may also take place at ordinary temperature with fuming sulphuric acid. (2) The leuco body is heated with p-toluidinehydrochloride and p-toluidine at 100‹-120‹ C. while stirring. The product is diluted with alcohol, and filtered, leaving dark-blue bronze-lustred needles. The acid potassium salt of di-p-toluidodioxyanthraquinone sulphonic acid crystallizes from water in black needles, soluble in concentrated sulphuric acid. The dyeings are purer and yellower than the above. (3) The leuco body is heated with alpha-naphthylamine hydrochloride, alpha-naphthylamine, and glycerine for several hours to 100‹-140‹ C. while stirring. The product is diluted with alcohol, filtered, and the residue washed and re-crystallized from benzene. The di-alpha-naphthylidodioxyanthraquinone crystallizes in dark prisms, and is soluble in benzene to a green, and in concentrated sulphuric acid to a blue, solution. Tha sulphonic acid is obtained, and the green solution precipitated with common salt. The dye-stuff dyes wool somewhat duller shades than the p-toluidine dye-stuff.

Title: Stoppering Device for Preserve Jars and the like
Inventor: MARTINI HERMANN
Filed: 1903-06-30
Granted: 1904-04-28
Abstract: 14,590. Martini, H. June 30. Stoppers.-In a stoppering-device for vessels containing liquid alimentary products, or solid products preserved in a liquid medium, means are provided whereby air may be exhausted from the filled and closed vessel without the application of heat. An arched cover a, Fig. 14, consisting of an elastic membrane, is fitted over the vessel, a packing-ring e, retained in the flanged edges of the cover, pressing upon the edge of the vessel. The cover a is provided centrally with a dome b, having an opening c in its upper portion. Fitting over the dome b, is a casing g, containing a spring- controlled valve q, adapted to press in an airtight manner upon the dome b. The valve q consists of an elastic ring, fixed around, or seized in an airtight manner by, a disc z, and the casing g is covered by a plate h provided with central openings. A chamber l is inserted beneath the dome, and retained by spring portions m, Fig. 3. Within the chamber l is arranged a float t provided centrally with a flared opening, and covered by an elastic plate v. After the vessel has been filled, and the stoppering-device placed in position, air is exhausted by suitable means through a tube y. When the air is exhausted, the cover a sinks, and the liquid rises in the dome and lifts the float, so that the elastic plate v bears against and conforms to the inner surface of the top of the dome. The valve q is kept firmly seated by the spring u, and the pressure of the atmosphere. To open the vessel, the rod s is pulled so as to open the valve, when the cover becomes arched upwards, and the whole can be removed and used again. Means may be provided for locking the valve so as to prevent it becoming loose during transport. In a modification, a float t<1>, Fig. 17, is used, this float consisting of an elastic body filled with air, and having its weakest cross-section at the liquid level S. When the vessel is exhausted, the air inside the float expands, and presses the float tightly against the cylindrical walls of the dome.

Patent GB-190321094-A (GB)
Title: Improvements in Water-gauges.
Inventor: DITNER ALBERT
Filed: 1903-10-01
Granted: 1903-11-05
Abstract: 21,094. Ditner, A., and Engasser, E. Oct. 1. Water-level indicators.-The escape of steam and water from water gauges when the glass breaks is automatically prevented by providi n g self - acting valves outside the steam and water passages. The piston b works within the casing a which is secured to the cock-attachment u. The piston-rod e passes through the neck y, and terminates in a conical valve c. The tube d leads to the boiler direct. The spring f normally keeps the piston down, but, on the glass breaking, the pressure forces up the piston b until the valve c sits in its seat t, and thus prevents further escape of steam or water. An exactly similar device is adapted at the other end of the gauge. Instead of using the springs f, the pistons b may be loaded, and the tube d may lead to the cock-attachment u, instead of direct to the boiler.

Title: Improvements in or relating to Blind Stitch Sewing Machines.
Inventor: NORTH WILLIAM STANLEY
Filed: 1904-04-26
Granted: 1904-06-09
Abstract: 9555. North, W. S. April 26. Blind-stitching machines; double-loop stitching- machines; needle shields.-In a blind-stitching machine, the curved needle F, Fig. 8, is attached to the swinging arm G and works in guides c to prevent buckling when passing through thick material. The looper 14, Fig. 17, pivoted in the ball sleeve 17, is provided with a to-and-fro and an up-and-down motion by the crank 10, and is moved to take and leave the thread loops by the crank 16, which carries the pivot 17. The looper has a thread of its own. Work-supports.-The work-support is pivoted at D<2> and is held in position by a spring and plunger 44 which holds a projection D<3> against an adjustable stop near a cam 34. The support may be lowered by a hand-lever E<1> or a foot-treadle, either of which can independently rotate the camlever 34. To lock the support in its lowest position, the lever E' is depressed until the toggles 27 pass the centre, and, in order to be able to raise it by the treadle, a spring 47 is arranged to press the toggles back when the weight is relieved by the treadle. To prevent breaking the needle, a stop is automatically inserted behind the projection D<3> while the needle is in the cloth and so prevents the lowering of the work-support. Feed.-The machine has an upper and a lower feed. The lower dogs, which project through the V-shaped ridge E on the work-support, are moved to and fro by a crank 48 and up and down by a crank 54, Fig. 9. The upper dogs 56, acting on the surface of the material, are fixed to a shaft 59 which is mounted in levers 60 and caused to oscillate about 62 by the shaft u.. A small rotational movement, given to the shaft 59 by a crank 72 through a link and crank, causes the dogs to move up and down. The crank 72 is normally locked with crank 73, but, when the work-support is lowered, a projection 77, Fig. 8, rotates a lever 74 and withdraws a catch from a slot 75 in the crank 72. In this way, the upper feed-dogs are automatically released and are raised by the spring 76 when the work-support is lowered.

Patent GB-190410199-A (GB)
Title: Improvements in or relating to Automatic Weighing Machines for Weighing Oil and the like Liquids
Inventor: HIPKINS WILLIAM EDWARD
Filed: 1904-05-04
Granted: 1905-02-08
Abstract: 10,199. Hipkins, W. E. May 4. Liquid-weighers; automatic-feed weighers.-Relates to apparatus for weighing oil and like substances, and consists essentially of a weigh-beam A, Fig. 2, a delivery shoot D with valve H, a hopper C, Fig. 6, and a valve or piston P, for delivering the substance after weighing. If the scale-pan is loaded while the hopper on the other end of the balance near the projection M<1>, Fig. 2, is empty, the latter end rises and the projection M' is brought into contact with the spring F, thus forcing the socket F<1> and plate E<1> into a position slightly above that shown, and opening the valve H to its fullest extent. The roller L then rides on the roller G'. Liquid is discharged into the hopper until the combined weight of the liquid and valve &c. is greater than that in the scale-pan, whereupon the hopper side of the beam falls and partially closes the valve, as shown. The links I, I<1> partly straighten out, and the stud K sliding to the end of the slot K<1> prevents the beam from falling any further. The liquid now flows in slowly, until the projection M', by falling with the beam, engages one end of the trigger G, thus freeing the roller G<2> from the roller L, and allowing the links I, I' to come into line and the valve to close completely. As the link I' falls, the end J<2> of a lever 0 pivoted at J<3> falls also ; and the other end rises, and with it the finger T<1>, Fig. 6, thus releasing the togglelever S from the spindle Y and allowing it to fall slightly. This throws the valve P open, and most of the liquid escapes from the orifice W the remainder being caught in the narrow-necked funnel V<1>, and serving, by its weight, to counterbalance the weight of the arm X and to prevent the return of the valve P during the draining operation.
