Granted: 1979-12-25
Abstract: A B S T R A C T              This invention relates to an end cap for use with a hot top slab for a casting mould of generally rectangular shape.  Such cap comprises a plate adapted to bear against an inwardly facing surface of a hot top slab.          One edge of this plate is bent to define a passageway to receive an edge portion of a wedging plate, the passage being downwardly and inwardly inclined in the direction of a corner of the casting.  Means are provided to secure the plate to the hot top slab.   This structure is an advance over what was previously used, such as grooves formed in the hot top slab to receive wedges.   Weakening of the slabs is avoided thus enabling materials to be used in making the slab which would not be strong enough to provide a satisfactory grooved slab.  It is unnecessary to provide thick slabs with the accompanying disadvantage of a shoulder on the casting.          The wedging action is improved.  There is also improved ease and reliability with respect to the holding of the lining of the mould in position.

Abstract: OIL RECOVERY BY SURFACTANT WATERFLOODING WITH ALIPHATIC SUBSTITUTED SUCCINIMIDO ARYL HYDROXY SULFONATES          Abstract of the Disclosure Waterflooding process for the recovery of oil from a subterranean oil reservoir rich involves the injection into the reservoir of an aqueous solution of an aliphatic substituted succinimido aryl hydroxy sulfonate or its corresponding succinamic acid derivative.  This surfactant functions to reduce the oil-water interfacial tension and also functions in the presence of divalent metal ions, such as calcium or magnesium, as a thickening agent to increase the viscosity of the injected water.  In carrying out the invention in oil reservoirs in which the connate waters exhibit a divalent metal ion concentration of at least 0.2 weight percent, the surfactant may be injected in a relatively fresh water which exhibits a divalent metal ion concentration less than that of the reservoir water.  Thus as the surfactant solution mixes with the reservoir water, the divalent metal ion concentration of the solution is increased with an attendant increase in its viscosity.
