Patent GB-421379-A (GB)
Title: Improvements in or relating to the production of cellulose from lignocellulosic materials
IPC: D21C3/20
Filed: 1933-06-12
Abstract: <PICT:0421379/IV/1> Lignocellulosic materials are subjected to treatment with organic solvent compositions capable of dissolving lignin therefrom so that the dissolved lignin is removed from contact with the materials after at most a period short compared with the time taken for a substantially or nearly complete extraction of the lignin.  Suitable solvents are alcohols, poly-alcohols such as ethylene glycol, diethylene glycol, or glycerol, acetone, dioxane, or other solvent described in Specification 416,416, [Group VIII]. These may be used alone, in admixture with each other, or with water. According to one method, the lignocellulosic material is subjected to the action of the solvent intermittently for short periods, for example of 10 to 20 minutes, the liquor being run off and replaced by fresh solvent after each extraction.  Instead of using fresh solvent, the used liquor may be cooled to separate the dissolved lignin, and re-used.  For example, a battery of autoclaves may be employed, and the liquor discharged from one autoclave may be fed, after cooling to precipitate the lignin and re-heating, to the next, and so throughout the battery.  In another method, the materials are subjected to an uninterrupted treatment with the solvent, for example, the solvent may be caused to flow through the materials continuously, or at intervals, e.g. of 5 to 20 minutes.  Using the apparatus described, solvent is pumped by means of the pump 28 from the storage vessel 6, through the heater 7 to the extraction tower 3, which contains the cellulosic material supported on a wire mesh 9.  The pressure is increased by means of an air compressor connected with the inlet 12. The solvent passes through the cellulosic material into the cooling and settling vessel 5.  The pressure in this vessel is p  about atmospheric pressure.  Condensed solvent in the vessel 5 flows through the overflow into a storage tank 6, as do also solvent vapours condensed by the condenser 21.  The pump is operated so that the level of liquid in the storage tank remains practically constant. The extraction may follow a preliminary treatment with water, dilute alkalies or acids.  The solvent may be employed together with small quantities of acid or basic substances, e.g. hydrochloric or sulphuric acid or an organic acid such as formic or acetic acid, or oxides or hydroxides of alkali or alkaline earth metals.  Proportions of 0,1 per cent or less are mentioned.  The cellulose may, after suitable pretreatment, be employed for the production of cellulose esters or ethers. Specifications 249,173, [Class 2 (ii)], 398,801 and 416,549 also are referred to.

Title: Improvements in or relating to self-closing cocks
IPC: F16K21/12
Filed: 1932-06-02
Abstract: 402,757. Slow-closing cocks. HAMILTON, W., Woodlands, Wadhurst, Sussex. June 2, 1932, No. 15700. [Class 135.] Relates to a self-closing cock of the type in which the flow of liquid is cut off gradually by a main valve retarded by a plunger moving in a dash-pot communicating with the inlet. According to the invention, the cock comprises a dash-pot plunger adapted to act as a sealing- valve after the main valve is closed, a stem carried by the plunger to act as the main valve, a release valve so constructed and arranged relatively to the main valve and plunger as to provide communication between the dashpot and liquid outlet, and a carrier or cage member in which the main valve slides, and which is formed to mask and unmask the valve according to the position of the plunger and stem. In the form shown in Fig. 1, the main valve consists of a tube 6 having grooves 8 which allow water to flow from the inlet 2 between the valve and the ported cage 9 and out through the passage 25 in increasing quantities as the valve is depressed. A plunger 5 attached to the tube 6 is adapted to move in a dash-pot 4. Initial movement of the knob 7 opens the relief valve 14 in the plunger 5, and allows water to pass between the stem 21 and the tube 6 and through holes 27 to the outlet 25, further movement of the knob 7 bringing it in contact with the upper end of the tube 6 and opening the main valve. Any water leaking through the bushing 28 of the main valve when the valve is open escapes through holes 32 in the ring 30 which holds the cage 9 in position, and escapes by the outlet 24. On releasing the knob 7, the valve 14 closes immediately under the action of its spring 16, and the valve 6 is slowly returned to the closed position by water accumulating below the plunger 5. After the main valve has closed the washer 5A contacts with the ridge 13 and forms a seal. In the modified form shown in Fig. 2, the stem of the main valve tube 44 is tapered so that when depressed, it admits water from the inlet 35, through holes 50 in the dash-pot cylinder 39, between the valve and the bore of the cage 40, and through holes 56 to the lower part 38 of the outlet. The closing action of the dash-pot is assisted by a spring 48, and the plunger 45 seats on a washer 46 on the cage 40. Leakage through the gland 43 forming the upper part of the cage 40 escapes through the upper part 37 of the outlet.
