Title: Determination of sulphur in petroleum samples
Inventor: MORRIS PETER REGINALD
IPC: G01N23/08
Filed: 1959-03-04
Abstract: 886,030. X-ray determination of sulphur. ESSO RESEARCH & ENGINEERING CO. Feb. 29, 1960 [-March 4, 1959; Sept. 9, 1959], Nos. 7517/59 and 30772/59. Class 40(3). The sulphur content of a: petroleum stream is measured by measuring the absorption of X-rays from a tritium source on passing through the stream. A gaseous or liquid petroleum stream passes along the channel 1, 2, 3 between beryllium windows 4, of a cell having an X-ray source of tritium absorbed on a zirconium foil 5, and a Geiger counter 6. The output from counter 6 is compared in a "backing-off" unit with the output from a counter in a similar cell containing a known sample, or applied to a voltage divider. Allowance may be made for variations in the carbon/hydrogen ratio in the petroleum sample by measuring also the absorption of # rays from a strontium 90 source and using the count to modify the output of counter 6.

Title: Improvements in and relating to the extraction of an organic gelling compound from vegetable matter
IPC: C08B37/12
Filed: 1945-03-29
Abstract: An organic gelling-compound is extracted from vegetable matter by soaking it in water to remove sugar, glucosides or other soluble material, and then boiling in a solution which has been rendered alkaline by the addition of a substance which hydrolyses to form an alkaline solution.  The vegetable material, preferably in the green state, is soaked for approximately two hours in water at a temperature of about 120 DEG  F., the material having been previously crushed or macerated if necessary to break down the hard covering. The material is then washed free from the soaking-liquor and is boiled for about half an hour in a .75-1 per cent solution of sodium carbonate; for each 100 grams of material, a solution of 7 grams of washing soda in 2000 c.c. of water may be used.  The resulting liquor, after removal of solid matter, may be used as a colloid or may be filtered and concentrated by precipitation as by the addition of a salt solution, alkali or acid, and/or dehydration, e.g. evaporation. Specification 537,794 is referred to.

Filed: 1931-03-16
Abstract: 368,991. Calculating - apparatus. ANDERSEN, K. I., Lundbaek, Nibe, Denmark. March 16, 1931, No. 8061. Convention date, March 17, 1930. [Class 106 (i).] A calculating device for summing respectively the ordinates and the abscissµ of a number of points on various curves comprises two relatively-movable cylindrical surfaces, one carrying the curves, and a sleeve which can slide and rotate relatively to both surfaces and which carries two index points. The embodiment described is for determining the weights of various kinds of fodder which should be fed to dairy cattle in order that they may produce a given weight of milk. Within a hollow cylinder 1, 1<1> slides a tube 3 secured to a second cylinder 2. A sleeve 10 with reading apertures 11, 12 provided with indexes i<1>, i2 slides over both cylinders. A series of curves M, starting from a common transverse plane and each relating to a different kind of fodder, is marked on the cylinder 2. If developed, the ordinates of these curves would represent protein values and the abscissµ " fodder units." The curves are marked along their lengths with divisions representing weights of fodder. In use, the index i<1> is set to the zero of one of the scales M and the sleeve 10 moved to allow the index to follow the curve until a desired weight is indicated. By moving the tube 2 the zero of another curve M is brought beneath the index i<1> and the process repeated, the result being that the index i<2> indicates the sum of both the ordinates and the abscissµ of the chosen points on the scales M. On the cylinder 1 is a curve A graduated along its length in weights of milk produced and plotted to ordinates representing protein values and abscissµ representing fodder units. If the amounts of fodder selected by the curves Mare correct, the index i<2> coincides with the required milk yield on the curve A. In a modification, the sleeve 10 is transparent and a series of interchangeable cylinders 1 bearing different curves A is provided.

Filed: 1944-04-29
Abstract: 581,023. Locking nuts. NORONHA, J. De. April 29, 1944, No. 8090. [Class 89 (i)] Nuts are locked by providing a seating for a thin flat blade having a cutting edge that penetrates the bolt threads. A cylindrical extension 4, Fig. 3 of the nut has a transverse slot 5 to accommodate the blade 9 and a packing-piece 10 having a head 10b projecting over the end of the blade. To lock the nut the packing-piece is driven in till the head enters a recess 8 forcing the blade into the threads and upsetting the body of the packing- piece to lock the blade in the slot. A cap 7, Fig. 1, that is a press fit on the part 4 is then driven into place, the cap being closed by a hexagonal part 7a. The part 7 of the cap has a cruciform slot at M that registers with a hole 6 in the part 4, and the projecting corners of the slot are pressed in to engage the hole and lock the cap that in turn locks the packing- piece. To remove the nut, the cap is turned by a spanner to bring the corners of the slot into register with the unoccupied recess 8 when the cap can be prized off the nut and the packing 10 prized out of the slot bringing the blade with it. In a modification, the blade is mounted in a slot in a separate lock nut and in addition to the blade 9 and packing 10 there is a locking strip 12, Fig. 12, whose end 12a is held in a cross slot 13. The end 12b is bent across the parts 9, 10 which are then forced into locking engagement with the bolt as shown on the right of the Fig. producing a ridge K that resists bending of the end 12b under back pressure from the blade. In a further form the parts 9, 10 are mounted in a slot in a plug 14 screwed into a hole in the nut. The blade and packing are maintained in locking engagement with the bolt threads by a strip 18 sliding in a transverse T-slot in the head of the plug.

Vicinal diols are prepared by reacting an acyclic or alicyclic olefin with an organic hydroperoxide in the liquid phase in the presence of boric acid or boric anhydride and liberating the free diol from the diol borate ester produced. The process may be carried out at 70-180 C. at atmospheric pressure or above either in the presence of: (a) a solvent inert to oxidation and hydroxyl groups, e.g. an excess of the olefine, whereupon the intermediate diol borate ester is decomposed by heating with water or an alcohol to give the free diol along with boric acid or a volatile ester thereof, or in the presence of: (b) a lower carboxylic acid as diluent, e.g. acetic acid, whereupon the intermediate diol borate ester is heated with water in the presence of the said acid and the resulting mixture of diol mono- and diesters with the said acid are hydrolysed to the free diol under alkaline conditions. The acyclic or alicyclic olefin may be an alkene of 2-12 carbon atoms, e.g. propylene, or a cycloalkene of 6-12 carbon atoms e.g. cyclohexene or cyclododecene. The hydroperoxides of cyclohexane or cumene are preferred and are used in the presence of 2-4 gram atoms of boron per mole of the hydroperoxide. The alcohol corresponding to the particular hydroperoxide employed may also be isolated from the reaction.
