Abstract: Abstract of the Disclosure A foam monitor senses the dissipation of foam within a transparent tube and employs a series of vertically spaced light emitting diodes which are cyclically pulsed to provide repetitive sequential scanning of the tube contents and a series of photo-responsive elements are axially spaced along the diametrically opposite side of the tube and positioned to monitor corresponding intermittent light paths that may be received from the corresponding light emitting diodes. The intermittent light paths are monitored during each scanning cycle to provide a pulse train which is indicative of the relationship between scanned levels containing foam and scanned levels void of foam. The pulses produced over a predetermined number of repetitive scans are totalized to provide an analytical measurement of the foam dissipation qualities for the liquid involved.

Abstract: CONTROL OF INCOMPETENT FORMATIONS WITH THICKENED ACID-SETTABLE RESIN COMPOSITIONS          Abstract A method and composition is provided for positioning a polymeric material having particulate matter disposed therein in a subterranean formation penetrated by a wellbore.  The composition consists essentially of a hydrocarbon oil, a quaternary salt of an essentially undegraded, cellulose sulfate, solid particulate matter in an amount equal to from about 0.25 to about 22 pounds of particulate matter per gallon of hydrocarbon oil and an acid-settable thermosetting resin in an amount equal to from about 0.1 to about 5.0 gallons per cubic foot of particulate material.  The composition is placed in contact with a subterranean formation in a wellbore by a method comprising injecting a first mixture consisting essentially of said quaternary salt of an essentially undegraded cellulose sulfate mixed with hydrcarbon oil followed by the injection of the composition with a post injection of an additional quantity of the quaternary salt in oil.

Abstract: MAGNETOSTRICTIVE ALLOY THIN FILM ELECTROPLATING            METHOD                 Abstract of the Disclosure A thin film of low magnetostriction Permalloy* 80% nickel - 20% iron ? 1% is electroplated onto a substrate in a bath having a ratio of from 5.8:1 to 23:1 ratio of Ni to Fe ions with a plating current density from 10 ma/cm2 - 200 ma/cm2 when plating in sheet form or an Ni/Fe ratio of from 25:1 to 86:1 with a current density of from 2 ma/cm2 -  60 ma/cm2 when plating through a mask.  The fluid in the system is constantly mixed, replenished with fresh iron, acid, and other reagents, is adjusted in temperature and subjected to a continuous laminar regime of mixing.  The Fe++ ion concentration required is inverse to the circulation of bath fluid across the substrate.          Fresh solution is added to the bath from a reservoir where the above adjustments are made.  The inlet for the fresh solution is at the lower end of the plating chamber and directed at a bath mixer which includes a slot through which the fresh solu-tion is directed to optimize mixing in the plating chamber.          Complexing agents are avoided.  High speed plating is obtained with about 24.4 g/l of Ni++, 1.05 g/l of Fe ++, 25 g/l of H3BO3, 0.2 g/l of Na saccharin and a pH of 1.5 to 3.6.          * Trade Mark

Abstract: ABSTRACT OF THE DISCLOSURE             An input/output system includes at least a pair of processing units and system interface apparatus for com-paring the results produced by both halves of the pair during normal system operation under control of a main or host processing unit.  The system interface apparatus in-cludes comparison circuits for detecting a mis-compare between the results of each half and sequence control logic circuits which are conditioned upon the occurrence of a mis-compare to unlock or deconfigure the pair to establish in a predetermined manner which of the proces-sing units is faulty.  The system interface apparatus, following signal indications of a certain minimum confi-dence within a processing unit, continues testing of the processor using stored diagnostic routines to determine which one of the processing units is good.  It then stops the operation of the bad processing unit and enables sys-tem operation to be continued with the good processing unit.  To ensure reliable processing, both halves of the pair are tested when a miscompare cannot be related to an error condition associated with one of the pair notwith-standing the fact that the first processing unit tests well. Following reconfiguration, the operating system associated with the system provides periodic testing of the good pro-cessing unit, thereby ensuring that the system continues to operate reliably.

Abstract: ABSTRACT OF THE DISCLOSURE     An oxygenator for blood is disclosed which comprises means for removably holding a membrane oxygenator unit, means for conveying blood to a patient through the oxygenator unit in a first flow path and back to the patient, and means for supplying oxygen gas through the oxygenator unit in a second flow path separated from the first flow path in the unit by a semi-permeable membrane.  A housing holding the membrane defines a blood flow path on one side of the membrane and an oxygen flow path on the other side of the membrane, the blood and oxygen flow paths being sealed from one another, with the housing defining inlets and outlets for each of the oxygen and blood flow paths.  The oxygenator unit holding means carries a plate which has an oxygen inlet manifold port positioned to communicate with a mounted oxygenator unit, to provide a sealed oxygen flow path through the plate into the oxygenator unit and to provide for dispersal of effluent oxygen in a plurality of directions, thereby preventing the accidental obstruction of the oxygen outlet of the unit.
