IPC: A62D1/00
Filed: 1953-07-23
Abstract: A powder consisting at least predominantly of individual crystals of sodium bicarbonate of an axial length ranging between 0.01 and 0.1 m.m. obtained by artificial crystallization which have not been crushed, is used for fire-extinguishing purposes.  The ratio between the sizes of the largest and smallest crystals preferably should not exceed 10:1, and in an example is 2:1.  Other fire-extinguishing salts may be added in minor proportions.  A very small percentage of a water-repellant substance such as paraffin wax, stearic acid or a stearate, e.g. of magnesium may be added.

IPC: F23N3/00
Filed: 1924-09-02
Abstract: 221,503. Thomas & P. LevÛque, M. Sept. 3, 1923, [Convention date]. Air supply, regulating.-In a furnace supplied. with air under pressure, the fire-box door and a damper in the air supply conduit are connected so that when the door is open the damper is closed and means are provided for ensuring reengagement of the co-operating parts during closing of the door so that when the door is fully closed the damper is open. As shown, thepivoted damper 4 in the compressed air conduit 3 is connected by a lever 14 to a rod 12 which is slotted at 16 to engage with a pin 17 on the furnace casing and is provided with a groove 11 to accommodate the end 10 of the usual pivoted fire-door handle 7. In operation, when the handle 7 is lifted to disengage it from the catch 9, the rod 12 is lifted but not sufficiently to close the damper 4 completely, the final closing movement being effected by the pressure in the conduit 3. The extra movement of the damper is permitted by the slot 16 and ensures that the rod 12 is in such a position that on closing the door 1, the handle 7 re-engages in the groove 11.

Patent GB-585765-A (GB)
Title: Grid control for static current converters
IPC: H02M1/04
Filed: 1944-11-02
Abstract: 585,765. Converting. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Nov. 2, 1944, No. 21438. Convention date, Nov. 25, 1943. [Class 38 (ii)] In a grid-controlled static current converter, in which the voltage active in effecting the commutation decreases during the commutation, such as an inverter or frequency changer, the grid potential of the relieving valve path at the instant of initiating the commutation is derived from a voltage in the main circuit determining the commutation in such manner that the grid potential follows the instantaneous variations of that main circuit voltage. Curves I, II, III represent anode voltages in a threephase system of three valves, the thick lines showing when the valve paths are open. By the control circuit of the grid 2 of the main valve in phase II, the grid 2 is respectively positive and negative when auxiliary valves 5, 4 are open. The potential across part of a resistance 13 connecting grid 2 and anode 3 is balanced against the suitably phased voltage from a secondary of a transformer 16 which is shown in Fig. 1 by curve A drawn to a scale enlarged in the ratio of the whole resistance 13 to its tapped part. The resultant of these two voltages is applied to the grid of an auxiliary valve 17. This grid becomes positive at the instant the balance is reversed, shown at a and passes an impulse through transformer 10 to make the grid of valve 4 negative whereby the main valve is ignited. An advantage of having curve A sinusoidal is that, if the valve in phase I has failed to ignite, then at b the valve in phase II will take over the load from phase III. Other circuits are described, Figs. 3, 4, 5 (not shown), in which the sinusoidal voltage A is replaced by a voltage of wave-form B, resulting from the addition to a steady D.C. potential of one half of a sine wave, the top portion of which is cut off by the relieving action of a glow-discharge lamp. In these cases it is also arranged, by the effect of the addition of a small inductance to the lower end of resistance 13, that the primary ignition impulse is released only when the time derivative of the voltage effecting commutation is negative. Fig. 6 shows the xesistance 13 and small inductance 18 connected in series between anode and cathode of the main valve, and so connected to the auxiliary'valve 17 that the instant of initiation of commutation is determined by a given proportion prevailing between the voltage and its time derivative. The invention may be applied to a system of valves with igniter anodes instead of grids.

Title: Recovery of acetylene
IPC: C07C7/11
Filed: 1960-06-21
Abstract: <PICT:0883200/IV (b)/1> Acetylene is recovered from a gas stream also containing water, diacetylene and other heavier acetylenes by (1) contacting with a first stream of lean solvent selective for acetylene to remove water, (2) contacting the dried gas with a stream of acetylene-rich selective solvent to absorb diacetylene, and some of the other heavier acetylenes, (3) contacting the resultant gas with a second stream of lean selective solvent to absorb acetylene and remaining heavier acetylenes, (4) stripping the resultant solution to recover acetylene and a third stream of lean selective solvent, (5) combining a minor portion of this third stream with the wet and diacetylene-rich solvents from steps (1) and (2) and (6) stripping this solvent to remove water and acetylenes.  A gas stream containing acetylene, e.g. from a pyrolysis operation, in line 1 is mixed with dimethylformamide in line 2 in an amount of 0.25% mol of the solvent in the main absorption step or 0.6-2 mols per mol of water in the gas.  The mixture is cooled to -20 DEG F. to 20 DEG F., and the gas and liquid separated.  The gas in line 7 is contacted in tower 8 with dimethyl-formamide containing acetylene from line 9 in an amount of about 1.4% mol of the total acetylene-rich solvent from absorber 12 or 3-20 mols per mol of diacetylene under conditions such at - 20 DEG F. to 20 DEG F. and 14.7-50 p.s.i.a.  The gas leaving by line 11 is contacted in absorber 12 with fresh solvent from line 13. Acetylene-rich solvent leaving the bottom is divided, part being sent to absorber 8, the remainder passing first to carbon dioxide stripper 17 where by heating carbon dioxide and some acetylenes are removed and returned to absorber 12.  The solution is then stripped in stripper 22 to recover acetylene and some heavier acetylenes by line 23, the stripper having a bottom temperature of about 326 DEG F. and a top temperature about 250 DEG F. at 20 p.s.i.a.  The lean solvent is passed to holding tank 30 part being bled off by line 28 in an amount of 0.32% mol of that passing to tank 30 or 0.5%-4% wt. of that used in the main absorption step. Diacetylene-rich solvent from absorber 8 is heated and flashed in drum 33, e.g. at 14.7-50 p.s.i.a. and 120 DEG F.-180 DEG F. to remove other acetylenes which are returned by line 34 or alternatively water is added to displace other acetylenes.  The solvents from lines 6, 36 and 28 are combined and stripped in column 38, e.g. with methane from line 39, water being added by line 41.  Gases are removed overhead and pure solvent recovered by line 43.  The column may have a bottom temperature of 300 DEG F.-400 DEG F. and a top temperature 80 DEG F.-150 DEG F. at atmospheric pressure.
