Title: Improvements in Water Closet Flushing Apparatus and the like.
Inventor: WILLIAMS HENRY MARTYN
Filed: 1899-12-05
Granted: 1900-02-17
Abstract: 24,185. Williams, H. M. Dec. 5. Water-waste preventers.-Regulator valves in service pipe. Fig. 1 shows a plan partly in section. When the balanced lever 16 is raised, a cam on its axis acts upon the end of a stem 10, and opens the valve 4 against a spring 12 and allows a flush to pass which, as it passes the end of a pipe 9 leading to the crown of the closet outlet siphon, exhausts the air and starts the basin discharge. Automatic closure of the valve 4 is effected by the leaking of water into a vessel 19<a> on the end of the lever 16. The weight of this water ultimately lowers the lever 16, and leaves the spring 12 free to close the valve. The time of the flush is regulated by a screw 23 which controls the flow of water into the vessel 19<a>.

Title: Improvements in the Production of Dye-stuffs.
Filed: 1900-02-15
Granted: 1900-05-12
Abstract: 3041. Lake, H. H., [Chemical Works formerly Sandoz]. Feb. 15. Dyes, artifcial.-New dyes of the oxazine group, which dye wool in an acid bath, as well as with chromium mordants, bright blue shades fast to light and milling, are produced by substituting for one of the hydroxylic hydrogen atoms in gallocyanine, or its derivatives, or its condensation products with amines or phenols, an alkylsulphonic radicle XSO2, in which X represents the residue of benzene, toluene, or xylene. This is effected by acting upon the gallocyanine in an alkaline solution with an aromatic sulphochloride. For example, gallocyanine sodium salt is produced by acting upon the hydrochloride with sodium carbonate, and it is heated with benzene sulphochloride at 70‹-80‹ C. for about six hours. The dye, which is soluble in water, is then precipitated by common salt. The dyes obtained from prune, gallamine blue, and the like are rendered soluble by heating them in alcoholic solution with sodium bisulphite, or bisulphite compounds of the gallocyanines may be used instead of the gallocyanines themselves. Mordant-dyeing thiazines, viz., the brilliant alizarine blues, may also be similarly converted into more brilliant and greener dyes.

Inventor: BEAUREGARD VICTOR
Filed: 1900-05-16
Granted: 1900-07-07
Abstract: 9074. Beauregard, V., and Gooding, C. S. May 16. Door-closing apparatus; door checks.-Consists of an adjustable link 5, pivoted to the door frame and also to the end of a piston cylinder 1. A toothed casing 18, containing a spiral spring, is fixed by the bracket 21 to the back of the door 23. One end of the spiral spring is fixed to the casing, while the other end is connected to a boss forming part of the end of the cylinder 1 ; the spiral spring thus always tends to decrease the angle between the link 5 and the cylinder 1, and close the door. Slamming of the door is checked by the air enclosed between the piston 27 and the cylinder, the piston being forced in by the teeth on the casing 18 acting on the rack 25. The escape of the air is regulated by a screw valve 3. When the apparatus is mounted on the other side of the door, the positions of the link 5 and the cylinder 1 are interchanged. Either the checking or the closing part of the apparatus may be used by itself.
Patent GB-190009344-A (GB)
Title: Improved Vacuum Evaporating Apparatus for Separating Common Salt (Chloride of Sodium) from Solutions, especially from Brine.
Inventor: VIS GERHARD NICOLAAS
Filed: 1900-05-21
Granted: 1900-09-29
Abstract: 9344.. Vis, G. N. May 21. Evaporating brine.-Relates to the vacuum apparatus, preferably arranged for multiple-effect, for the evaporation of brine and other solutions containing common salt, which is described in Specification No. 16,738, A.D. 1899. That Specification describes a method of periodically discharging the separated salt from the evaporators A through the tube C into a tank, by admitting air into the evaporators so as to destroy the vacuum. This invention consists in providing electrical means for operating the cocks on the airadmission pipes, the electrical device being itself operated by variations in the vacuum caused by periodically working the vacuum pump faster than the normal rate. The cock 11 of each air pipe is provided with a slotted arm 10, which is fitted on a pin which is fixed on a core 9, which lies within two solenoids 4, 6 which lie in two circuits comprising also a battery 3. Connected with the upper part of the evaporator A is a tube 1 closed at its upper end and with its lower open end dipping into an open tube 2 containing mercury. The wire 5 is passed through the upper end of the tube 1, and extends downwardly to a point just above the normal level of the mercury in the tube 1. The wire 7 extends downwardly in the tube 2 to a point just above the normal level of the mercury in this tube. The wire 8 extends downwardly nearly to the bottom of the tube 2, and is always in contact with the mercury. In the position shown, the cock 11 is closed. When the pump is worked faster, the vacuum is increased, and the mercury rises in the tube 1 and completes the circuit through the solenoid 4, so that the core 9 is moved to the right hand and the cock 11 is opened. The consequent destruction of the vacuum causes the mercury to fall in the tube 1, and to rise in the tube 2, so as to close the circuit through the solenoid 6, whereby the core 9 is drawn back again and the cock 11 is closed. The vacuum being restored, the mercury assumes the level shown, and the cock remains closed until the pump is again worked quickly.

Title: Improvements in Machines for Folding Table Napkins and other Articles of Linen or the like.
Inventor: COLLON EUGENE
Filed: 1901-01-18
Granted: 1902-01-18
Abstract: 1218. Collon, E. July 10, A.D. 1900, [date applied for under Sec. 103 of Patents &c. Act, A.D. 1883]. Folding napkins &c.-Relates to improvements on the invention described in Specification No. 2711, A.D. 1900, for folding table napkins and other articles of linen &c. The article to be folded is pushed along a table c until its edge is at about the position z over the carrier cylinder b, which is covered with a layer of felt. The counterweighted roller v, carried on an arm of the lever Wand actuated by a cam x, is then depressed to press the article against the cylinder, which then carries it under the spring-pressed roller a. By the further rotation of the cylinder, the article is fed under the knife e until one-third of its length rests on the pivoted-platform d. When in this position, the end of the platform d is moved from the cylinder by cam action, and the knife is at the same time actuated to crease or fold the article at one-third of its length. The partially-folded article is then carried by the cylinder b under the end of the platform d and under the roller f to a second similar folding-arrangement, by which a second fold is made. The folded article then drops down along guide-plates 1, 2, which, by cam action, are moved apart to allow the article to fall in an uncrumpled condition on an endless belt i, by which it is carried to a corresponding machine for making corresponding folds transversely. It is finally allowed to fall into a receptacle provided with movable lateral sides, and a movable bottom counterbalanced by weights.

Title: Improvements in Match-making Machinery
Inventor: DININNY JR FERRAL CARLTON
Filed: 1901-08-16
Granted: 1901-11-16
Abstract: 16,509. Lake, H. H., [Dininny, F. C.]. Aug. 16. Cutting-up, splitting, and slicing.-A machine for use in making matches comprises apparatus for cutting splints from veneers, means for ejecting the splints from the cutting-apparatus and delivering them to receivers, and apparatus for introducing the splints into carriers or frames. The veneers 26 are fed intermittently along a trough 25 by means of one of two pushers 34, attached to handles 35 which are loosely mounted on lugs 33, forming parts of racks 32, one at each side of the trough. By this means a new set of veneers can be inserted in the feed trough behind a previous set, and the whole can be fed forwards without interrupting the operation of the machine. The lugs 33 slide along fixed side rods 30, and the racks are actuated by pawls 36 connected to oscillating arms 37, to which motion is transmitted from an eccentric on the main shaft 4. Either pawl 36, together with the retaining-pawl 43 used in connection therewith, may be thrown out of action by means of pins mounted on shafts 44, provided with handles 49. The leading veneers are successively fed to series of rotary cutters 6, by a plunger 28, actuated by an eccentric or shaft 4. The splints cut from the veneers are pushed away from the cutters by series of slotted teeth 78, Fig. 10, projecting from plates 77, into the space between the cutting-edges of the several cutters. Projections 80, carried by bars 79 secured within recesses in the cutters, serve to force the splints into recesses 51, beneath which is a plate 57 for temporarily supporting the splints. Instead of teeth 78, a series of spring tongues secured to the cutters may be employed. The reservoirs are movably connected to carriages 84, which are reciprocated by means of cams 54, levers 88, and links 89, and the receivers are mounted to travel along divergent guideways 52, formed in a table 2. When the carriers are moved in opposite directions by means of the links 89, the receivers gradually separate as they travel along the guideways, and are brought over perforated carriers or frames 58, to which are attached perforated locking-plates 110, 111, Fig. 23, which are movable relatively to the frames, and to each other. The perforations in the locking-plates are extended laterally and are formed with rounded shoulders 118. The splints are forced into the frames by reciprocating plungers 60, actuated by means of cams 63. An intermittent motion is given to the carriers by means of reciprocating racks 71, which engage with racks 70 mounted on the sides of the frames.

Title: An Improved Process for the Production of Nitric Acid and Apparatus therefor.
Inventor: PAULING HARRY
Filed: 1902-08-21
Granted: 1903-06-04
Abstract: 18,427. Pauling, H. Aug. 21. Electric furnaces.-An arc furnace for use in the production of nitric acid by the direct union of nitrogen, oxygen, and steam consists of a chamber having carbon electrodes 5, beneath which are heat regenerators 2, 3, separated by a wall 4, and cut up into intercommunicating compartments 8, 9, 10,11. These gradually diminish in size towards the inlet and outlet passages 6, 7. The compartments 8, 9,10,11 are first heated up by passing air through the furnace alternately in the direction of the arrows I and of the arrows II. When the compartments nearest the carbons are almost as hot as the arcs themselves, the process of making nitric acid is proceeded with, either with the continued use of the arcs, or after withdrawing the electrodes. In the latter case, the chambers gradually become cooler, and after a time have to be re-heated as before.

Title: Improvements in or relating to the Extraction of Precious Metals from Ores.
Inventor: WEBB CHARLES HENRY
Filed: 1902-11-07
Granted: 1904-02-06
Abstract: 24,417. Webb, C. H. Nov. 7. Filters of large capacity.-In extracting precious metals, such as gold and silver, from their ores by solutions of cyanide, bromine, chlorine, or iodine, the crushed ore is charged into a rotating cylindrical vat provided with filtering-devices. The solution is agitated with the ore under air pressure, and the filtrate is preferably drawn off by a suction pump, and, after precipitation of the metal, is returned to the vat. Figs. 1 and 3 show a construction of filter vat. The cylindrical vessel or vat a is supported in slings b carried over pulleys on a shaft, and is rotated by suitable gearing. Within the vat a grating is formed by a number of strips of wood f secured to the inner surface at an angle to the axis. Over the strips a layer of filter cloth or other porous support g, such as coco-nut matting, is fixed, and on it may be placed a layer of sand &c. j, kept in place by wire gauze or the like k. A central cylindrical filter may also be fitted within the vat. The ore is introduced and the residues removed through manholes z, and the solution or water through a pipe t. Air is forced into the vat by means of the pump n, the valves being suitably manipulated. The de-oxygenated air is allowed to escape through a valve y operated by a star-wheel at intervals. The filtrate is drawn off after a certain interval through the pipe k<1> by the same pump n or another pump, and discharged into a tank s for recovering the metal. The cylinder is rotated, while the solution is being withdrawn, so that a layer of slime accumulates over the filter surface and assists the filtration. The solution is then run into a tank s<1>, and pumped back to the tank u for re-use.

Abstract: 27,253. Lake, H. H., [Stone, J. S.]. Dec. 10. Telegraphs.-In a syntonized system of wireless telegraphy, one or more circuits acting inductively on each other are used in connection with the vertical conductors of the transmitter and receiver to ensure exact tuning and selective telegraphy. Fig. 7 shows one arrangement of a transmitter. Oscillatory currents generated in the coil I<II> by the battery, automatic break p, and condenser C", induce oscillatory currents of higher potential in the circuit I<11>2, I<1>1. In this circuit are a sparkgap s, an inductance coil L', and a condenser c<1> in shunt with the spark-gap. The high-frequency oscillations induced by the passage of sparks are communicated by induction to a third circuit I<1>2, I1, L, and from the latter to the vertical conductor. The receiver, Fig. 8, has a similar arrangement of circuits to take up the oscillations from the vertical conductor v and impress them on the coherer K in the last circuit. Modifications are described in which two or more sets of differentlytuned circuits act on the same vertical conductor, thereby making it possible to transmit and receive more than one message simultaneously.
