Title: Improvements in the Treatment of Flue Gases.
Inventor: DAVIS FREDERICK WILLIAM
IPC: B01D47/06
Filed: 1918-05-21
Abstract: 127,095. Davis, F. W. May 21, 1918. Potassium and sodium salts. - Flue gases containing steam, such as the gases from kilns in which wet slurry is burnt in the manufacture of Portland cement, or from kilns or furnaces used for dehydrating aluminium hydroxide, are passed through an apparatus such as that shown in the Figure. The gases are drawn by a fan F through a chamber B, in which dust &c. is deposited, and then through a chamber C, where they are washed by sprays of water issuing from a pipe, as shown, the quantity of water employed being so regulated that the temperature of the gases is reduced below the boiling-point of water, but no substantial quantity of the steam therein is condensed. The gases and steam pass through baffle-plates E to the fan and exit shaft G. The soluble matters such as the salts of sodium and potassium, are dissolved in the spray water, which collects in the bottom of the chamber C and passes thence to a filter H and cooler J. from which it is returned by a pump K back to the spray pipe, or, when sufficiently concentrated, it is passed to a tank 0, in which the solids in solution crystallize. The apparatus may be fitted with a thermometer for indicating the temperature of the gases; and the chamber C may be fitted with an inspection window and with a water gauge by which the depth of liquid in the bottom of the chamber may be ascertained.

Abstract: 541,876. Extraction of phenolic bodies from mineral and tar oils. STEAUA ROMANA SOC. ANON. PENTRU INDUSTRIA PETROLEULUI. May 10, 1940, No. 8484. Convention date, May 12, 1939. Drawings to Specification. [Class 91] The polymerization product which is obtained when cracked benzine is treated with decolourizing earths, for example according to the Gray system, is distilled, and the distillation product in which are concentrated all condensation products of a phenolic nature is treated with alkali lye. This treatment effects an extraction of all compounds of an acid character. The lye, the strength of which is preferably between 35‹ and 42‹ Be, may be diluted with water to form an aqueous solution which on treatment with an acid separates into two layers, the upper layer consisting of the extracted organic acidic substances. Specification 499,312 is referred to.

Further, the sections may be annular members inclined to the axis of the cylinder. In all embodiments, the maximum current to the sections is limited by resistances which may, in the last described embodiment, be housed in the electrode body, current supply to the electrode being by a single collecting ring.

Title: Improvements in Devices for Throwing Successively a Series of Projectiles by Means of Centrifugal Action.
Inventor: FRISCH AUGUST
IPC: F41B3/04
Filed: 1917-06-23
Abstract: 133,074. Frisch, A. June 23, 1917. Machine guns.-Relates to centrifugal machine guns having a rotary radial guide-race for the projectiles, and consists in providing an horizontal guide-race in a wing rotating about a vertical axis, so that rotation about a vertical axis is imparted to small flat projectiles as they roll successively outwards in the guide-race. Fig. 1 shows a vertical section through one form of the gun, which, in use, is mounted on a tripod 10, Fig. 2, the front and rear legs of which are each pivoted to trunnions 9 on the gun. Disk-shaped projectiles 6 with bevelled edges are fed upwards through a hollow spindle 1, which is rotated by an electric motor 13 within a casing 3, and which carries at its upper end a wing with arms 2 having radial grooves 5 to guide the projectiles outwards towards the opening in the casing 4 through which they are discharged. The grooves 5 also support a carriage 22 which is reciprocated in the guides. as the wing is rotated, by the action of a wormwheel 20 moving round a fixed worm 15. The worm-wheel 20 is mounted on a shaft 18 rotating in bearings in a bracket fixed to the arms 2, and carries eccentrics 21 engaging the carriage 22. The uppermost projectile is threaded on to a pin 25 and is moved into the guide 5 by the carriage 22. The pin 25 is mounted on a lever 24 which is rocked to release the projectile by the contact of the lever with the core of a solenoid 27 depressed when the circuit through the solenoid is closed by operating a. switch 29<a> on the handle of the sighting-device 29. The sighting-device is carried by an arm 16 which, together with an arm 26 carrying the solenoid is movable about a vertical axis to vary the angular position at which the projectiles are released. The projectiles are fed to the hollow spindle 1 from magazine elements 35 which are rotatably mounted in disks 34, and, when brought in turn beneath the central tube 1, they rotate with it. When the magazine elements are empty, arms 38 on the spring platform 36<a> engage with a pawl 40 and release the upper disk 34, which, under the action of torsion spring 41, rotates on a shaft 32 to bring the next magazine element into position. The elements are closed at the top by covers 36 which are moved aside by a projection 42 on the spindle 1. In a modification, the central spindle is rotated by a friction disk adjustable to vary the speed of rotation, and the release of the projectile is effected by mechanical means from a trigger on the sighting-device.

Title: Improvements in electric regulators

Filed: 1926-04-07
Abstract: 250,590. Allmõnna Svenska Elektriska Aktiebolaget. April 11, 1925, [Convention date]. Regulation, automatic.-In a regulator having an auxiliary member, responsive to a quantity associated with the normally regulated quantity to prevent the former from exceeding a limit, the auxiliary member is arranged so that it is in equilibrium in any position between certain limits. In the example given, a vibrating regulator arm 41 which is normally responsive to voltage coils 32, 35 and is controlled by the difference in tension between springs 43, 71, the latter normally reacting on a fixed abutment 72, is made responsive to values of excessive current by a spring 74, the normal tension of which does not exceed that of the resultant of springs 43, 71 but which increases above it under the influence of an auxiliary current-controlled member such as an induction disc 77. This remains in equilibrium over a considerable range of movement since the spring anchorage, which below the critical value of the current lies upon a cylindrical portion of a core 76, at higher values passes on to a spiral portion such that the torque on the disc 77 remains the same as the spring is stretched to its limit. In a modification employing electromagnetic traction on the spring 74 a progressively decreasing air-gap may be employed. If the limited quantity be a mechanical one, such as speed, the current relay may be replaced by mechanism, such as a centrifugal governor. In polyphase systems a relay may be associated with each phase all operating upon a common control member.
