Abstract: A method of adapting a synthetic substrate for immobilisation of a target molecule thereon.

Abstract: A technique is provided for the alignment of an H/D puller for use in a cyclotron. One aspect of the technique comprises magnetically attaching a pair of feeler gages to an alignment tool for use in aligning the H/D puller. The magnetic retention of the feeler gages allows a field engineer to make the desired adjustments to align the H/D puller. Another aspect of the present technique provides for the H/D puller to include a replaceable tip such that the tip may be replaced without removing the H/D puller. Because the H/D puller is not removed and replaced, the alignment of the H/D puller to the ion source is maintained.

Abstract: A method for inhibiting the formation of scale in waters having a high barium content and low pH comprises the addition of an aqueous solution of a phosphonate of formula: wherein Z=—CHR1PO3R2 R=H, CH3, C2H5 or M R1=H, CH3, CR3, C6H5, SO3H2 M=alkali metal or ammonium ion n=2-6, preferably 2-4 m=2-6, preferably 2-4 a=2-10, preferably 2-4 b=2-10, preferably 2-6 x=0-6, preferably 0-3 y=0-6, preferably 0-2 provided that when y=o at least one of n or m is greater than 2.

Abstract: A method of recovering or increasing the recovery of oil and/or gas from an underground formation involving injecting into the formation, preferably in the form of an aqueous solution, at least one mono alkyl ether of polyethylene glycol in which the alkyl group has 3-5 carbons and the polyethylene glycol contains 3-6 ethylene oxy units e.g. butyl ether of triethylene glycol. Especially preferred are mixtures comprising that and at least one mono alkyl ether of mono or di ethylene glycol e.g. a mixture of butyl triglycol ether, butyl tetraglycol ether, butyl pentaglycol ether and butyl diglycol ether. The method of the invention may be applied to well stimulation treatments such as water blocking, sand consolidation, sandstone acidizing and methods of increasing the recovery of oil such as tertiary oil recovery.

Abstract: The invention relates to a process for increasing the effectiveness of production chemicals by reducing the number of squeezing and shut-in operations needed to increase the production rate from an oil well. The process includes injecting into an oil-bearing rock formation matrix a water-miscible formulation comprising: (a) a water-miscible surfactant which is an alkyltriglycol ether and (b) at least one water-miscible oil field or gas field production chemical. Components (a) and (b) are introduced either as a pre-formed, single, homogeneous composition, or simultaneously in parallel or sequentially in either order into the rock formation. After introduction of (a) and (b) into the oil-bearing rock formation, the well is shut-in for a period and, subsequently, the oil-bearing rock formation matrix is over-flushed with an oil.

Abstract: A catalyst composition prepared by reacting together:(a) a source of a Group VIII metal,(b) a bidentate phosphine ligand having at least two phosphorous atoms joined by a bridging group of the formula --NR.sup.2 (CX)NR.sup.2 where X.dbd.O, S or Se, each R.sup.2 is the same or different and is a hydrogen or hydrocarbyl group, and(c) a promoteris disclosed. The catalyst composition is used for preparing polyketones.

Abstract: A novel 2-Methylbutoxy ethoxyethanol and a method for the preparation thereof. The use of the novel 2-Methylbutoxy ethoxyethanol as a solvent or a coalescing aid in aqueous formulations used as coatings and paints, a cleaning solvent for electronic components, a domestic and industrial hard surface cleaner, a component of oil well drilling muds, a fuel additive, and a solvent for liquid detergents.

Abstract: This invention relates to aqueous resin formulations comprising as cosolvent an alkoxy ethoxyethanol which (i) has 4-8 carbon atoms in the alkoxy group, (ii) has a boiling point at atmospheric pressure within the range from 200.degree. to 350.degree. C. and (iii) in mixtures with n-heptane in the ratio of 30:70 by weight respectively has specific miscibility characteristics. The cosolvent acts either as a solvent or coalescing aid in aqueous formulations used as coatings and paints.

Abstract: This invention relates to a process for increasing the effectiveness of production chemicals by reducing the number of squeezing and shut-in operations needed to increase the production rate from an oil well. The process includes injecting into an oil-bearing rock formation a water-miscible formulation including as components: (a) a water-miscible surfactant which is an alkyltriglycol ether and (b) at least one water-miscible oil field or gas field production chemical, said components of the formulation being introduced either as a pre-formed single composition, or simultaneously in parallel or sequentially in either order into the rock formation via the production well.
