Title: Process for the recovery of sulphur dioxide from gases
IPC: C01B17/60
Filed: 1941-02-06
Abstract: 547,001. Sulphur dioxide. FEENY, C. J.. (Consolidated Mining and Smelting Co. of Canada, Ltd.). Feb..6, 1941, No. 1600. Drawings to Specification [Class 1 (ii)] Sulphur dioxide is absorbed and liberated in a continuous process in a cycling ammonium, bisulphite-ammonium sulphite solution, the total weight of ammonia in these compounds being 8 to 13 per cent. of the weight of solution and the cycling solution in the absorption stage being maintained nearly saturated with respect to ammonium sulphate and unsaturated with respect to the other salts present. The cycling solution is withdrawn from the absorption stage, heated to expel sulphur dioxide and water vapour until the ratio of sulphur dioxide in ammonium bisulphite to that in sulphite is reduced to not less. than approximately 87:13 and cooled to crystallise an amount of ammonium sulphate equivalent to that formed by oxidation in the preceding stages, the sulphate is removed, the solution replenished with water and ammonia and returned to the absorption stage. Specification 489,745 is referred to.

Title: Improvements in or relating to electrical overload protective systems
IPC: H02H7/26
Filed: 1947-01-17
Abstract: 620,439. Electromagnetic switches; protective cut-out systems. RUDD, C. H. Jan. 17, 1947, No. 1603. [Class 38(v)] In a protective system, each of a number of overload relays, located at successive points of a supply system to be protected, has a solenoid adapted to increase the operating time of the relay in response to a current transmitted over auxiliary contacts, which close immediately on an overload, of the relay succeeding it in the system, so that the relay nearest to the fault will operate before the others. In the application to a radial feeder 1 with a branch feeder 2, the current flowing from left to right, the auxiliary contacts A of the branch relay Rl nearest to the junction are in parallel with those of the relay R immediately to the right of the junction, either of the relays being able on fault to energize the coil S of the relay R immediately to the left of the junction, according as to whether the fault is in the branch 2 or the right-hand portion of the feeder 1. On a fault at F, on the branch, the contacts A, of the relays R to the left of the junction and those of relay R1 next to the junction, close to energize the coils S of the preceeding relays R, which operate after a time delay and only if the relay R1 next to the junction fails to clear the fault. The system may be applied to a radial feeder without a branch feeder, by the omission of the relays R1, Fig. 1, (not shown). The invention may be applied to a ring-main feeder with or without a branch feeder, Figs. 3 and 4 (not shown), by the use of directional and overload relays, wherein the contact device A of each relay comprises a contact which can selectively engage either of two fixed contacts, according to the direction of current flow, to increase the time-delay of the relay immediately to the left or right of the said relay. In the application to the protection of a number of feeders connected by a common bus-bar, Fig. 5, (not shown), one of the fixed contacts of each device A is replaced by a number of contacts equal to one less than the number of feeders and in series with the coils S of the other feeders, so that on a fault in one feeder, the time delays of the relays in the other feeders are increased. Electromagnetic relays.-The time setting devices, Fig. 6, may comprise quadrants Q which rotate on overload. thereby permitting contacts A to close. Each quadrant carries two adjustable members M, N, adapted selectively to actuate the tripping contacts T, according to whether the coil S is de-energized or energized. The contacts T are carried by the pivoted armature P of the coil S, so that when this is energized, the contacts T are moved into the path of the member N. In a modification, Figs. 8, 9 (not shown), members M, N of equal length are arranged on either side of the quadrant Q, the armature P and contacts T moving sideways when the coil S is energized.

Abstract: 181,322. Williams, F. P. Habicht-, (known as Habicht, F. P.). June 1, 1921, [Convention date]. Void [Published under Sect. 91 of the Act]. Propelling, steering, and manoeuvring by air jets.-In ships propelled by air jets, a compressor forces air beneath the hull into a perforated pipe or channels formed by keels. the bottom of the hull sloping upwardly and rearwardly from the position at which the air conduit passes through the hull. Steering is effected by controlling the port and starboard jets. The air to the channels is controlled by a valve in the compressor suction or delivery pipes,. or by valves in the branch delivery conduits in accordance with the varying water pressure in the outboard passages. The boat k, Fig. 1, has a compressor e delivering to a perforated pipe h. In the modification, Fig. 4, the compressor delivers to a forward or rear channel d<1>, d formed between depending keel members c, the depth of the keels increasing from the compressor position forwardly and aft respectively. Instead of one channel between two keels, there may be a number of longitudinal channels between a number of keels, steering being effected by controlling the air jets. When the ship is out of trim the water pressure in the channels is unequal, and when there is a separate compressor to each channel the air delivery is regulated by a piston r, Fig. 8,. under the influence of the pressure in the delivery pipe p, acting on a throttle valve t in the compressor suction pipe m. Where one compressor feeds several channels, each branch is controlled by a valve 11, Fig. 9, moving over a port 14 in the pipe line 5, 6.

Filed: 1939-01-21
Abstract: 523,645. Recovery of sulphur-dloxide. BACON, R. F. Jan. 21, 1939, No. 2144. Convention date, Jan. 21, 1938. [Class 1 (ii)] Relates to processes for recovering sulphur dioxide from mixtures with other gases, in which the sulphur dioxide is absorbed in an aqueous absorbing medium, and the latter is heated to expel the sulphur dioxide. According to the invention, the aqueous medium contains a borate as an absorbent of sulphur dioxide. Further, the process may involve the use of a boric acid in conjunction with a borate or with an absorption agent other than a borate, e.g. a sulphite to aid in the liberation of the absorbed sulphur dioxide by heating. Preferably sodium, potassium or ammonium tetraborates and magnesium metaborate are employed for the absorption, and orthoboric acid for aiding in the liberation of the sulphur dioxide. The borate may or may not be in saturated solution, or it may be in excess of the amount required for saturation. Liberation of the sulphur dioxide is most effectively performed when the absorbing medium is saturated with free boric acid at boiling temperature. The temperature of absorption may be anywhere between the freezing point of the solution and 75‹C., and for liberation of the absorbed sulphur dioxide the solution may be heated to a temperature from 85‹C. to the boiling point. Usually the working temperatures are 70-75‹C. and about 85‹C. respectively. Tables are given showing results obtained with varying concentrations of reagents (borax and other borates and sulphites with or without free boric acid in each case), under various working conditions. Apparatus particularly suitable for carrying out the invention is described in Specification 523,646, [Group XII].
