Title: A process for desulphurising mineral oils
IPC: C10G21/22
Filed: 1938-08-11
Abstract: 512,395. Desulphurizing oils motor fuels. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ, and FIFE, J. G. Aug. 11, 1938, No. 2759/39. Divided out of and addition to 512,364. [Class 91] Low boiling mineral oils are freed from sulphur compounds, such as mercaptans, thioethers and alkyl thiophenes, without affecting aromatic hydrocarbons or mono-olefines, by extracting the oil with a selective solvent for sulphur compounds, separating the extract and treating it at a temperature not above 40‹C., with an aliphatic sulphonic acid, whereupon a further rafflnate and extract are formed and separated. The final raffinate free from sulphur compounds is combined with the first rafflnate to form a motor fuel. Naphtha, gasoline, kerosene, gas oil, from straight-run, cracked, or polymerized oils may be treated. Selective solvents specified are, sulphur dioxide and acetone, thiophene aldehyde, methyl or ethyl cyanide, ethyl cyanoacetate, nitroaniline, aniline, ethylene diamine, methoxy methyl cyanide, and methyl carbitol. Sulphonic acids specified are, methyl, ethyl, propyl, isopropyl, butyl, and amyl sulphonic acids, or the corresponding chlorsulphonic acids, used alone or diluted with a polar diluent, such as one of the selective solvents, alcohol, acetone, or water, or a hydrocarbon diluent, such as Edeleanu extract. Such diluted sulphonic acids are used with oils containing large amounts of olefines. Oil is introduced into an extraction zone B to which a selective solvent and an auxiliary solvent such as naphtha flow in countercurrent. The rafflnate containing paraffins, naphthenes and mono-olefines, passes to a separator 33 and then tank 34, and the extract containing aromatic, unsaturated, and sulphur compounds, passes to a still 32. The. solvent-free extract passes to a second countercurrent extraction zone A, which may be a packed tower, or mixers and settlers, where it is treated with the sulphonic acid and a light naphtha or white oil, as diluent. The extract free from hydrocarbons, passes to a settler 9 in admixture with water or alcohol which dissolves the sulphur compounds, leaving a sulphonic acid layer which passes to a vacuum still 11. The alcohol and auxiliary solvent are recovered from the extract in a still 14. The sulphur-free rafflnate consisting of aromatic and unsaturated compounds and auxiliary solvent is washed with water in a separator 19, distilled with steam at 21, and, if desired, finally treated with clay. This is then united with the first raffinate. In an example, 100 parts of cracked distillate boiling at 150-200‹C. containing 1.1 per cent. sulphur is treated with sulphur dioxide and octane, yielding 20 parts of extract containing 4.4 per cent. of sulphur. The extract is treated with methyl sulphonic acid and isopentane, yielding 12.2 parts of rafflnate containing 1.2 per cent. of sulphur, and an extract containing 14 per cent. of sulphur. The combined rafflnates form 92 parts containing .3 per cent. of sulphur.

Filed: 1953-02-03
Abstract: 767,502. Laminated materials; coated flexible sheet materials; pressing coated fabrics. YARSLEY, V. E., FLAVELL, W., and FRENKEL, B. April 23, 1954 [Feb. 3, 1953], No. 3050/53. Class 140. In making resin-bonded products by subjecting to heat and pressure a web or a number of superposed webs that have been coated or impregnated with a thermosetting resin such as a catalysed and, may be, styrenated unsaturated polyester resin, the heat and pressure are applied by immersing the resin-treated web or assembly of webs W in a non-metallic, substantially inert liquid L such that the web or webs will float therein. The web or webs are conducted along the underside of a top platen or force P, the submerged portion of which may be rectangular, trapezoidal or, as shown, triangular in longitudinal cross-section. The pressure may be solely due to the head of liquid, or additional pressure may be applied by pumps, the entry of the web or webs and the subsequent exit of the cured product then being through seals capable of withstanding the pressure. The liquid may be heated by an immersion heater or heat applied externally of the tank. The resin may be applied to the web or webs by immersion, spraying, or rollercoating, and the web may be heated before entering the curing liquid tank. The webs may be of textiles, e.g. glass fabric, paper, or asbestos. The liquid may be water, an aqueous salt solution, a fused organic or inorganic salt such as magnesium chloride hexahydrate, or a liquid or fused organic compound such as glycerol. Specification 734,079 is referred to.

Abstract: 701,680. Filleting fish. BAADER, R. May 21, 1951 [May 19, 1950], No. 3062/53. Divided out of 701,650. Class 28(2) In a fish filleting machine in which the various filleting &c. tools are allowed to actuate by the released timed movement of a bar 365, such timed movement is accelerated for a shorter fish by a feeler shoe 322 when the shoe drops down as the fish is pulled away from under the shoe. Normal actuation takes place when a camactuated lever 107 is rocked about 324 to the left whereupon an attached lug 331 pushes a lug 112 to the left which moves a latch 113 from under the holding-up part of a lever 114. The lever 114 then pivots down about 334 to raise its bar 365 at the other end, which bar initiates actuation of the tools. This actuation is accelerated for a shorter fish by coupling the lever 107 to a faster rocking lever 106 which then takes charge. Such coupling is done as follows. When the feeler 322 drops off a shorter fish a roller 323 also drops whereby a pawl 110 connected to lever 107 engages in a rack 108 connected to the lever 106. The rack 108 allows for automatic adjustment to varying lengths of fish.

Filed: 1943-03-02
Abstract: 570,986. Electric indicating systems. THORLEY, J. March 2, 1943, No. 3381. Addition to 551,376. [Class 40 (i)] [Also in Group XL] Comprises modification of the means described in the parent Specification for indicating the position of a wireless transmitter by means of a light spot projected on to a translucent map, the light passing through the point of intersection of diametral slots in two discs which are arranged under the map and are automatically rotated in respective correspondence with two spaced directional aerials so that each slot is constantly oriented in the direction of minimum sensitivity of the corresponding aerial. According to one modification, each or either rotating aerial is replaced by a fixed directional aerial connected to a goniometer, the rotating coil b of which is connected to the apparatus in the same way as the replaced rotatable aerial. In a second modification, the slotted discs are replaced by a light source a projecting a beam d through a slot in a rotatable housing and to the inclined reflecting surface of a pivotally-mounted strip c, which reflects it upwardly on to the map, the slotted light housing and the strip c being rotated in the same way as the corresponding slotted discs described in the parent Specification. In a third modification, the synchronizing impulses which maintain correspondence between the rotation of one of the slotted discs (or of the reflector c) and that of the distant aerial cause momentary energization of a magnet rotating with the former as it presses an armature, which is thus operated to alter resistance in the circuit of the driving motor of the magnet is behind or in advance of its correct angular position at the moment of energization.
