Abstract: 1,268,264. Sulphonated elastomers. ESSO RESEARCH & ENG. CO. 26 March, 1969 [27 March, 1968; 28 Oct., 1968; 11 March, 1969], No. 15830/69. Headings C3G and C3P. A sulphonated elastomer, which may be vulcanizable, contains monocyclic aromatic groups and 0.2-21 sulphonic acid groups per 100 repeating units. The elastomer may be a sulphonated styrene-butadiene copolymer, a styrene -butyl rubber graft polymer, a graft polymer of styrene or a styrene/acrylonitrile copolymer on polybutadiene, or a styrene-isobutylene copolymer. The elastomers may be made by dissolving the unsulphonated elastomer in a solvent which is also a solvent for an SO 3  complex, which is reacted with the elastomer and is made by reacting a Lewis base containing N, P or O and a sulphur trioxide donor, to introduce the required sulphonic acid groups into the elastomer. An ionically cross-linked elastomer may be made by neutralizing at least 1% of the sulphonic acid groups of the elastomer to form amine or metal salts, the amine may be primary, secondary or tertiary and the metal Na, K, Ca, Cu, Zn, Ni, Ba and/or A1.

Title: Water-mixed material discharge and recovery equipment - has pipes on gantry-mounted grab with hinging arm
IPC: B65G53/30
Filed: 1986-03-14
Abstract: The equipment discharges bulk material mixed with water into a vessel and recovers it again, there being a water overflow from the vessel. It has a discharge pipe with nozzle and a recovery pipe on an arm connected via a pump to a further nozzle. Also on the arm are spray nozzles connected to a pressure pipe, to mix the material in the vessel with the water again. The discharge (23), recovery (15) and pressure (16) pipes are each connected by a coupling turning on a horizontal and a vertical axis to a branch piece (19) controlled by valves, in turn connected to feed and discharge pipes, by which the pipes can be controlled. The couplings are on a crab (1) on which the arm (17) slews and hinges on vertical and horizontal axes, which travels along a gantry (4). A first flexible pipe is set between the branch piece on the crab and a fixed point on the gantry. The latter travels at right angles to the crab and spans the vessel in all positions. A second flexible pipe set runs between the gantry and a fixed point on the vessel. The arm length is sufficient to reach all points in the latter.

Title: Oil recovery method using an emulsion.
Inventor: BRAGG JAMES R
IPC: C09K8/82
Filed: 1999-11-23
Abstract: The disclosed invention provides a method for recovering hydrocarbons from a subterranean formation by injecting an emulsion, comprising oil and water, into the formation. More specifically, the emulsion is stabilized using undissolved solid particles, which are preferably at least partially oleophilic. The solids-stabilized emulsion may be used either as a drive fluid for displacing hydrocarbons from the formation or to produce a barrier for diverting flow of fluids in the formation. Such solid particles may be either formation solid particles (i.e., indigenous to the formation) or nonformation solid particles (i.e., obtained from outside the formation). Nonformation solid particles may either be naturally occurring or synthetic. Some preferred solids include clays, quartz, feldspar, gypsum, coal dust, asphaltenes, and polymers. Carbon dioxide or another gas may be added to the emulsion to adjust the emulsion's viscosity to the desired level.
