Title: Improvements in Throttle Valves.
Filed: 1905-10-31
Granted: 1905-11-30
Abstract: 22,234. Fraser & Chalmers, and Whitmore, F. L. Oct. 31. Rotary or oscillating disk or sector valves.- Throttle valves of the rotary-disk type are provided with means for slightly raising the valve from its seat during the operations of opening and closing. Fig. 1 is an elevation showing the general arrangement; Fig. 3 is a plan showing the actuating- mechanism for the main and pilot valves. The inlet branch (not shown) opens into the chamber 18, Fig. 1, and the steam passes through the valve 2 and out through the bottom of the casing. There is provided a recess 12, in which works a piston 9, the stem of which works in a guide 11 formed by the valve seat, within which also the lower extremity of the valve stem 8 rests. The space 12 below the piston, the space 15 below the valve 2, and the space 18 above the valve are all in communication with the three-way pilot valve 16, the first only of the steam passages being shown in Fig. 1. The operating-mechanism is shown in Figs. 1 and 3. Mounted on a lever 20, secured to the valve stem 8, so as to be free to rotate thereon is a two-armed lever 21 provided with pins 22, 23, to either of which is connected any usual means for operating the valve. The lever 21 carries a dependent trigger 24, which engages in a slot formed in the periphery of the lever 20. Between the levers 20, 21 is a spring connexion 26, which tends to keep one arm of the lever 21 hard against a stop 27 on the lever 20. Attached to the casing is a wedge 30 for throwing the trigger 24 out of the slot in the lever 20. A rod 31 connects the lever 21 to the lever 32 attached to the pilot-valve stem. When the main valve is closed, the pilot valve puts the spaces 12, 15 into communication and the pressure is the same on both sides of the piston, which lies in its lowest position under the action of its own weight. Upon the lever 21 being turned counter-clockwise, the pilot valve is first turned, whereby the space 15 is cut off and the spaces 18, 12 are put into communication. The excess pressure under the piston raises it, and consequently raises the main valve off its seat, until a collar on the piston spindle comes against the stop 35. In this position, the lever 21 will have been just brought to bear upon the stop 27 and the trigger 24 will have engaged the lever 20, so that any further movement of the lever 21 will take the lever 20 with it, thereby rotating the main valve. The reverse action is similar, the trigger being thrown out of engagement by the wedgeshaped projection before mentioned. In a modification, the piston is situated above the main valve and the casing is modified accordingly. The operating-mechanism is the same as that described above. The means described may be used to ease the valve without actually lifting it off its seat.

Patent GB-190525081-A (GB)
Title: Improvements relating to Solvents for Nitro-cellulose in the Preparation of Explosives
Filed: 1905-12-04
Granted: 1906-11-01
Abstract: 25,081. Cocking, A. T., and Kynoch, Ltd. Dec. 4. Nitrocellulose is gelatinized by dissolving it in a mixture of alcohol and acetone, in suitable proportions, the proportion of acetone in the mixture increasing with the degree of nitration of the nitrocellulose. These mixtures of alcohol and acetone are used as a solvent for nitrocellulose in the manufacture of explosives, and, as an example, in the incorporation of nitrocellulose with such bodies as nitroglycerin. In an example, in the case of " Mark " I Cordite," a mixture of 60 per cent acetone and 40 per cent alcohol, as equivalent to 100 per cent acetone, is used for solution or gelatinization just as is done when acetone alone is used. For " M.D. " Cordite," a mixture of 70 per cent acetone with 30 per cent alcohol is used. Nitrocellulose, as used in the manufacture of cordite and containing 90 per cent insoluble in ether-alcohol and 10 per cent soluble, takes 70 per cent acetone to 30 per cent alcohol, and that containing 10 per cent of the insoluble cotton about 40 per cent acetone to 60 per cent alcohol. A certain amount of ungelatinized nitrocellulose may be left in the colloid by using a suitable proportion of acetone to alcohol in the solvent.

Title: Improvements in Lixiviation Apparatus more particularly adapted for use in the Extraction of Sodium Nitrate from Caliche.
Inventor: HUNT WILFRED
IPC: C01D9/02
Filed: 1906-03-23
Granted: 1907-01-10
Abstract: 7007. Hunt, W., [Love, R. T.]. March 23. Extracts, decoctions, and infusions.-Relates to lixiviation apparatus for use in the extraction of sodium nitrate from caliche or in similar processes, such as the extraction of sodium carbonate in the Leblanc process, and consists in providing beneath the false bottoms of the bathing-tanks chambers, heated preferably by steam pipes or coils ; the extracting - liquor passes up through the false bottoms and the material treated and returns directly from the upper parts of the tanks through pipes or passages to the heating- chambers. In the apparatus shown in Fig. 2, beneath each tank is a chamber 14 containing plates 15 which carry tubes 16 ; steam is admitted to the space outside the tubes and between the plates by a pipe 17, an air-escape pipe 18 and a pipe 19 for discharge of condensed water being provided also. Liquor is run into the tank from the gutter 12 (of which there may be a series) by the gutter 37 into the gutter 25 above the surface of the material in the tank; from here it passes by the pipe 24 to beneath the lower plate 15 in the heating-chamber ; it then rises up through the tubes 16 and through the false bottom 21, becoming divided into four separate streams by means of radial partitions at the top of the heating- chamber and the radial bearers 22 which support the plates of the false bottom. When the tank is full, the supply is shut off and the valve 30 is opened, the valve 29 leading to the next tank being meanwhile kept closed ; circulation is then set up, the liquid rising through the aperture controlled by the valve 30 and flowing along the gutter 25 to the pipe 24 and so back to the chamber 14. The solution may be run off from the top of the tank by the stand-pipe or to the next tank through the aperture controlled by the valve 29, or from the bottom of the tank through the aperture controlled by the valve 34 ; or it may be discharged through the outlet 26. By means of this system of gutters and valves the usual operations, such as treating the fresh charge with the weak solutions used as final washings of other charges, are readily effected. Instead of using steam in the chamber 14, the beat of combustion from, say, a liquid-fuel burning-apparatus may be received therein : in another form of apparatus the chamber contains ordinary steam coils. In a third form of apparatus in which rectangular tanks are used, the heating-device consists of a series of horizontal pipes extending longitudinally beneath the false bottom ; these pipes open at one end into boxes connected to the steam supply ; in this apparatus the pipes which connect the upper gutters with the space below the false bottom are at the alternate ends of the successive tanks.

Window blinds. - The non - winding end of a blind roller a turns on a pivot c attached to a flat spring e secured to a bracket g, so that when the end e' of the spring is pulled outwards the roller may be detached. The axle k at the winding end turns in bearings in a bracket n, and is provided with a square or equivalent inner end i so as to cause the roller to turn with it. Arms or projections are secured to the axle k on the part between the bracket and the roller, and on the outside of the bracket at p<1>, and are adapted to engage with the upper arms s<1> of a pivoted lever r, the lower arms of which form a cord guide s, preferably bushed with lead so as to tend to keep the arms s<1> in engagement with the projections. The outer part l of the axle is also square, and is provided with a split pin q or a cotter to hold the arms p in place. The inner arms may be replaced by a collar, in which case only one-half of the lever r is provided. In a modification, the pivot at the non- winding end is fixed to the bracket g, and the axle k is capable of lateral movement so as to allow of the disconnexion of the roller. In this case, the arms are formed by grooving the axle throughout its length. Lateral movement is normally prevented by an eyelet o<1>, to which the end of the cord is secured and which is placed close to the inner face of the bracket n. When the cord is unwound, the eyelet may be moved so that it lies in one of the grooves in the axle, which may then be withdrawn from the roller and bracket. The invention is stated to be applicable to rollers having means of the kind described in Specification No. 22,551, A.D. 1906, for securing the blind to the roller.
