Title: Production of biodiesel having improved filtration characteristics
Inventor: KELLENS MARC
IPC: C11C3/10
Filed: 2008-12-16
Abstract: A process for the production and purification of fatty acid esters of lower alkyl alcohols with improved filtration characteristics comprises the steps of: a) transesterifying a mixture of fatty acid esters of glycerol with a lower alkyl alcohol while using an alkaline catalyst; b) separating the reaction mixture resulting from step (a) into a glycerol phase and a fatty acid lower alkyl ester phase; c) inactivating the catalytic intermediates present in said fatty acid lower alkyl ester phase; d) removing the lower alkyl alcohol from the mixture resulting from step (c) by evaporation at reduced pressure to a value of less than 2 % by weight; e) treating the evaporation residue resulting from step (d) with water; and f) isolating the fatty acid esters of lower alcohols by drying the product resulting from step (e). The fatty acid esters produced have low levels of impurities and haze and may be used in biodiesel fuel having a reduced tendency to block fuel filters.

Title: Heterogeneous proppant placement in a fracture with removable channelant fill
Inventor: LESKO TIMOTHY
IPC: C09K8/66
Filed: 2007-07-16
Abstract: A method of heterogeneous proppant placement in a subterranean fracture is disclosed. The method comprises injecting well treatment fluid including proppant (16) and proppant- spacing filler material called a channelant (18) through a wellbore (10) into the fracture (20), heterogeneously placing the proppant in the fracture in a plurality of proppant clusters or islands (22) spaced apart by the channelant (24), and removing the channelant filler material (24) to form open channels (26) around the pillars (28) for fluid flow from the formation (14) through the fracture (20) toward the wellbore (10). The proppant and channelant can be segregated within the well treatment fluid, or segregated during placement in the fracture. The channelant can be dissolvable particles, initially acting as a filler material during placement of the proppant in the fracture, and later dissolving to leave the flow channels between the proppant pillars. The well treatment fluid can include fibers to provide reinforcement and consolidation of the proppant and additionally or alternatively, to inhibit settling of the proppant in the treatment fluid.

Title: Induction of a physiological dispersion response in bacterial cells in a biofilm
Inventor: DAVIES DAVID
IPC: C09K23/00
Filed: 2008-05-14
Abstract: One aspect of the present invention is directed to a composition. The composition includes a dispersion inducer comprising: H3C-(CH2)n-CHmCHmR, where is a single or double carbon-carbon bond, m is 1 or 2, n is 2 to 15, and R is a carboxylic acid, a salt, an ester, or an amide, where the ester or amide is an isostere or biostere of the carboxylic acid. The composition additionally contains an additive component selected from one or more of the group consisting of biocides, surfactants, antibiotics, antiseptics, detergents, chelating agents, virulence factor inhibitors, gels, polymers, pastes, edible products, and chewable products. The composition is formulated so that when it is contacted with a biofilm produced by a microorganism, where the biofilm comprises a matrix and microorganism on a surface, the dispersion inducer selectively acts on the microorganism and has a suitable biological response without a required direct effect on the matrix to disperse the biofilm. The present invention is also directed to methods of using this compound.

Filed: 1962-03-16
Abstract: Detergent compositions obtained by a cosulphation process (see Division C2) contain Na2SO4, Na xylenesulphonate, and (1) tetrapropylenebenzene and its Na sulphonate, (2) polyoxyethylated nonylphenol and its Na sulphate, or (3) polyoxyethylated lauryl alcohol and its Na sulphate.  Products (2) and (3) are stated to be in paste form.ALSO:Organic compounds of different volatilities are co-sulphonated by introducing SO3 (diluted with an inert gas) and an excess of less volatile component into a reaction zone and, when this initial sulphonation is at least 25% completed, the more volatile component is introduced with additional diluted SO3 so that the total SO3 is within 5% of the stoichiometric amount for complete sulphonation of both components.  In examples, the more volatile component is xylene and the less volatile component is (1) dodecylbenzene derived from tetrapropylene, (2) polyoxyethylated nonylphenol or (3) polyoxyethylated lauryl alcohol.  In an illustrated embodiment, the organic compounds are passed as a free annular jet from high to low pressure zones to set up turbulence in the latter and the diluted SO3 is introduced into the centre of the annular jet.

Abstract: A substance suitable for the treatment of malignant tumours such as cancer, is prepared by treating (a) female animal blood taken during a period of from a few days before to a few days after delivery or taken during the first few days of menstruation, or (b) colostrum, undiluted with water, with an excess of a substantially non-aqueous water-miscible solvent to precipitate protein bodies containing the active substance, separating the solvent from and drying the precipitate and dispersing the dried precipitate in a neutral to slightly alkaline physiological solution.  In the example, human colostrum is centrifuged to remove fat, coated to 0 DEG  C. and allowed to stand.  Absolute alcohol at 0 DEG  C. is added slowly over 10 minutes, the mixture allowed to stand at room temperature for 50 minutes and then cooled to 0 DEG  C.  The precipitate is centrifuged and alcohol removed in vacuo at 45 DEG  C.  The precipitate is eluted with physiological saline solution containing disodium phosphate, stirred with bolus alba and centrifuged.  The liquid obtained contains the active principle and can be injected, taken orally, or freeze dried to form a powder which is mixed with sterile water as required.  Kaolin or fuller's earth may be used in place of bolus alba.  The non-aqueous solvent may be absolute ethyl alcohol or acetone.  Reference is made to the Cancer Act 1939.
