Patent GB-147905-A (GB)
Title: Process for the preparation of acids from natural gases, petroleum, mineral oils and the distillation and decomposition products of these substances, also from carburetted water-gas, oil-gas, producer-gas tar, water-gas tar, oil-gas tar and the like
IPC: C07C51/16
Filed: 1920-07-09
Abstract: The unsaturated aliphatic hydrocarbons contained in mineral oils or the liquid or gaseous products of their distillation or cracking, in natural gas, in the liquid or gaseous products of the destructive distillation of coal, wood, peat, shale, shale oils, or tar oils, or in carburetted water gas, oil gas, water-gas tar, oil-gas tar, lignite tar, producer gas, coal-gas, &c., are converted into fatty acids by first treating the gases, oils, &c. with mineral acids (sulphuric, hydrochloric, &c.), whereby the unsaturated hydrocarbons are converted into esters, and then treating these esters with oxidizing-agents.  For example, the acid sludge or acid resins obtained in refining mineral oils with sulphuric acid are treated with potassium bichromate and sulphuric acid.  Volatile fatty acids formed are distilled off with steam, and the non-volatile fatty acids remaining are freed from chromium oxide by boiling with dilute acid and may be converted into soaps by alkali.  Acid anhydrides may be formed in the oxidation process, these also being converted into soaps by alkali.  The more volatile acids (butyric, valeric, &c.) may be converted into esters for use in perfumery.

Title: Apparatus for effecting, in a submerged condition, the displacement of a movable member from one position into another
IPC: G01N1/12
Filed: 1961-06-05
Abstract: 903,378. Sampling liquids. PETTERSSON,L. O. June 5, 1961 [June 8, 1960], No. 20168/61. Class 106 (5). [Also in Group XXV] Apparatus for taking samples of water at varying depths comprises a bottle 27 held by a carrier 1 in which two rods 8, 18 are slidable and releasably connected by a permanent magnet 19 on one and a soft iron armature 15 on the other. The upper rod 8 is spring-loaded downwards and connected at 9 to a handling line and the lower rod 18 has soft rubber closure 29 for the bottle 27 which is held between levers 23 pivoted on a nut 22 and clamped on the bottle by screwing the nut on threads 21 so that cam surfaces 20 act on the levers. The apparatus is submerged to the desired depth with the rods separated and the closure 29 sealing the bottle and, by a jerk on the handling line, relative displacement of the carrier 1 and rod 8 causes the two rods to be magnetically interconnected. When the closure 29 is first moved away from the bottle mouth, it deforms slightly so that a slit 35 opens up and allows water to flow into the bottle through a passage 34 to equalize the inside and outside pressures. The closure is thus allowed to release completely from the bottle and the carrier descends relatively to the rods until the magnet 19 engages a shoulder between the two parts 2, 3 of the carrier. When it is estimated that the carrier has been filled, a second jerk on the handling line will separate the two rods, allowing the lower rod to drop and seal the bottle.

Title: Process for preparaing a silica-magnesia-fluorine hydrocarbon cracking catalyst
IPC: B01J27/12
Filed: 1961-06-07
Abstract: A silica/magnesia hydrocarbon cracking catalyst containing fluorine is prepared by forming an aqueous dispersion of silica hydrogel, adding simultaneously calcined magnesia and a mineral acid with continued agitation, thus forming a silica-magnesium oxysalt complex in situ, and then adding a compound yielding fluoride ions.  The silica hydrogel may be prepared by any known method, but preferably by treating an aqueous sodium silicate solution with a mineral acid to neutralise 80 to about 90% of the Na2O.  In the preferred method the pH of the resulting hydrogel is from 5 to 8, and the temperature during neutralization and subsequent ageing for 0,5 to 4,0 hours is 26 DEG -66 DEG C. Calcined magnesia, and a mineral acid such as sulphuric acid, are then added.  The amount of magnesia added is calculated to give a final catalyst with a magnesia content of preferably 20-30%.  The concentration of the acid used is preferably from 20-70% by weight.  The resulting silicamagnesium oxysalt complex is aged, suitably for 1-3 hours at about 82 DEG , filtered, and reslurried in water which may contain a magnesium salt.  To this slurry is added an aqueous solution of a compound yielding fluoride ions such as HF, H2SiF6, (NH4)2SiF6, NH4F or NH4,HF2.  The slurry is filtered, dried, washed with, e.g. magnesium sulphate and water, and redried at about e.g. 149 DEG C. to give a catalyst having a fluorine content of, e.g. 0,5-5,0% by weight.
