Abstract: 192,393. Zalocostas, D. G., (Assignee of Sheet Metal Workers, Ltd.). Jan. 25, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Sulphuric acid.-Apparatus for treating liquids with gases, particularly for absorbing sulphuric acid gas in acid liquor, comprises a tank 10, with inlets 15, 16 for liquid and gas, gas outlet 12 and liquid outlet 14, and a tier of pairs of horizontal plates 17, 20, supported by legs 23, and provided with a number of down-turned nipples. The lower plate of each pair is of smaller diameter, and has a serrated rim edge 18 set level with the rim edge 21 of the upper plate; each upper plate has a rimmed central orifice 24. The tank is charged with liquor, and gas, forced in through the inlet 16, spreads out in a layer along the underside cf the plates and is broken up as it passes beneath the serrated rims. The nipples permit of continuous circulation of the liquor, which when concentrated is drawn off through the pipe 14, fresh liquid being introduced at the inlet 15. In a modification, there is provided a valve control device operated by the pressure of the liquor when its density has increased to saturation point. By this means water is introduced into the tank and promotes circulation of liquor through a cooler coil to abstract heat evolved in the absorption of gas in the water.

Title: A new or improved permutation lock
IPC: E05B37/16
Filed: 1931-01-23
Abstract: 371,873. Permutation locks. ZUILI, M., 57, Boulevard de la Villette, Paris. Jan. 23, 1931, No. 2261. [Class 44.] A permutation lock, adapted particularly for use on cheque-books, portfolios, handbags, and the like, and applicable also to padlocks, comprises nested external and internal box-shaped elements 1, 6, the former being fitted with a series of transversely slidable buttons 3, the stems 3b of which carry pegs 4, and the latter being formed in its two sides with holes 6c corresponding in number and alignment with the buttons 3. A spring 8 is arranged at one end between the members 1, 6, and the latter carries at the opposite end a push button 7 by which it may be moved against the action of the spring to bring the holes 6c into register with the pegs 4. The latter are adjustable in the stems of the buttons 3 and can thus be set according to any desired combination. The locking action between the two parts A, B, which it is desired to secure together, is effected by the engagement of headed studs 10 mounted on a baseplate 9 in keyhole slots 6b formed in the base of the element 6, a detachable coverplate 11, having holes corresponding to the circular parts of the keyhole slots 6b being interposed between the base of the member 6 and the plate 9. In operation, when the buttons 3 corresponding to the predetermined combination are moved to disengage the pegs 4 from the holes 6c, the spring 8 forces the member 6 to the left, Fig. 1, and thus allows the studs 10 to be withdrawn from the keyhole slots 6b. Movement of any button 3, not forming part of the combination, not only fails to release the lock, but provides additional locking action by the engagement of its peg 4 in the corresponding hole 6c. Fig. 9 shows the application to a padlock, the element 1 carrying the buttons 3 (not shown) constituting, in this case, the lock casing. The internal element 6 is held between two slides 14 and the pushbutton 7 is extended to form the hasp.

Title: Improvements in and relating to Electromagnetic Switches.
IPC: H01H71/24
Filed: 1917-02-15
Abstract: 113,150. British Thomson - Houston Co., (General Electric Co.). Feb. 15, 1917. Electro-magnetic switches.-A lock-out switch has a shunt winding 10 mounted on the upper limb 12 of a U-shaped magnet frame, the lower limb being in three parts comprising a short central main pole-piece 14 and two longer auxiliary pole-pieces 15, one on each side of the main pole-piece and spaced therefrom. The switch member 18 is pivoted at 19 to a yoke extension 13 of the upper limb, and its lower end, which is under the influence of the main pole-piece 14 across the gap 29, carries on a non-magnetic extension 25 an adjustable armature 26 co-operating with the bent-over ends of the U-shaped magnetic frame 28 of the series holding-out winding 11. The yoke 13 also carries, pivoted at 31, a non-magnetic member 30 having an extended auxiliary armature 32 adapted to bridge the auxiliary pole-pieces 15. When the windings are energized, the armature 32 bridges the pole-pieces and a shoulder on the member 30 engages a plunger 33 on an extension of the switch member 18 and compresses the spring 21 thereby tending to move the switch member to the closed position. The armature 32 in its attracted position serves as a pole-piece for the lower end of the switch member 18 and diverts some of the flux from the gap 29 so that the switch member is magnetically balanced between the main pole-piece 14 and the attracted armature 32 serving as a polepiece. In consequence, in the attracted position of the armature 32, the lower end of the switch member is independent of variations of the current in the shunt winding 10. The switch member is maintained in the open position by the holding-out winding 11 against the action of the spring 21 until the series current falls sufficiently to release the armature 26, whereupon the lower end of the switch member moves out of the balanced position, and, under the influence of the armature 32 acting as a pole-piece, the switch member is magnetically brought into the closed position. Instead of employing the spring 21. which serves also for the resilient mounting of the contact 20 on the switch member, to produce the closing tendency a separate adjustable spring 37, Fig. 6, located in a housing in the member 30<1> may be employed. Specifications 23544/14, 112,996, and 113,001 are referred to.

Title: A process for the removal of sulphuric acid from sulphonation products of alkyl aryls
IPC: C07C309/31
Filed: 1959-01-22
Abstract: Sulphuric acid is removed from the sulphonation products of alkylated aromatic hydrocarbons by adding sodium sulphate, water and a water-immiscible ether to the product, whereby the mixture separates into two phases, one of which comprises a mixture of ether and the alkyl aryl sulphonic acid, substantially free of sulphuric acid, while the other phase comprises aqueous sodium bisulphate.  The sulphonic acid, so obtained, when neutralized with alkali gives an alkyl aryl sulphonate having an inorganic salt content of less than 2% by weight.  In an example, a mixture of alkyl benzene sulphonic acids, obtained by alkylating benzene with C10-C13 olefines, is sulphonated with oleum.  The mixture of sulphonic acid is partly deacidified by water-washing. The washed mixture, which stlil contains about 10% by weight of sulphuric acid, is stirred with di-isopropyl ether and an aqueous solution of sodium sulphate.  The mixture is allowed to separate into two layers; and the lower layer is discarded.  The ethereal sulphonic acid mixture is neutralized, while cooling, by adding an aqueous sodium hydroxide solution.  The ether is then distilled off; and a product is obtained which contains 1,7 per weight of sodium sulphate, based on sodium alkyl benzene sulphonate.
