Abstract: ABSTRACT OF THE DISCLOSURE In a data processing system whose operation is under the control of firmware words stored in a control store, a technique is provided by which a routine which has been temporarily suspended may be returned to.  The address of the last instruction executed in such routine prior to such suspension is stored and the routine is returned to by the use of such stored address with one bit thereof changed in state by use of an inverter. The control store is addressed by means of next address generation logic which includes a first multiplexer utilized to address the control store, which multiplexer has several inputs.  One of such inputs is received from a latching mechanism which allows more than one test condition to be simultaneously utilized for addressing the control store on a free flow basis. These test conditions, as well as information from an addressed control word, are utilized in a multiplexed arrangement as one input of the first multiplexer. By use of other inputs of such first multiplexer, the control store may be addressed by use of branch address information, as well as other test condition information.  A page register provides the page address, to a plurality of pages included in this control store with the locations in each such page addressed by use of the above noted multiplexer combination.

Title: Method of treating saline water
Inventor: BERTNESS THEODORE A
IPC: C02F1/02
Filed: 1982-04-23
Granted: 1986-01-14
Abstract: ABSTRACT OF DISCLOSURE     Method of treating saline water, for example brine produced along with oil from an oil field, to remove hardness as a precipitate of calcium and/or magnesium salts, also in some cases iron salts.  This is accomplished by direct introduction of energy in the form of steam or microwave energy or both.  Efficient removal of hardness is accomplished.          The resulting softened water, separated from solid precipitate (sludge) is used to generate steam for heating the saline water, to produce steam for injection into an oil field to promote recovery and/or for other purposes.  The heating of saline water to precipitate hardness is separated from the generation of high or low pressure steam, thus facilitating the treatment of the saline water.  In an offshore installation microwave energy is used for treating both to precipitate hardness and, in a separate vessel, to concentrate the slurry resulting from the first heating step to produce low pressure steam which can be condensed to provide a fresh water supply.

Abstract: PROSTHETIC ANKLE                         ABSTRACT A prosthetic ankle for use between the ankle block forming the bottom end of a prosthetic lower leg, and a prosthetic foot, comprising a securing bolt extending upwardly through a hole in the foot and screwed into a nut in the ankle block.  Under the head of the bolt are two cupped washers that provide a ball-and-socket connection which allows angular movement of the ankle block in all directions with respect to the foot, as well as rotational movement.  A paid of elastomeric material is interposed between the top surface of the foot and the bottom surface of the ankle block, and is cemented to the top surface of the foot.  The paid is of a thickness and hardness such that when the ankle block is leaned in any direction, the elastomeric material on the inside of the lean is compressed.  Pins project downwardly from the bottom surface of the ankle block and are received in cavities in the elastomer. When a torsional stress is exerted on the ankle block the pins exert a torsional shear in the elastomer. When the torsional stress is released, the elasticity of the elastomer causes the foot to be returned to the straight-ahead position.

Abstract: DOWN-LOCKING PUMP                Abstract of the Disclosure When the plunger is fully depressed, radially projecting lugs carried by the plunger adjacent its normally upper end may be received within corresponding notches in a collar through which the plunger recipro-cates, whereupon rotation of the plunger in a clockwise direction moves the lugs under overhanging shoulders of the collar so as to prevent extension of the plunger until it is intentionally unlocked from the collar.  A total of three lugs are utilized so as to provide three-point, stablized retention of the plunger in its locked-down condition, and one of the lugs and its corresponding notch is smaller than the other two so that the plunger can be locked only when it is in a certain, predetermined rotative position relative to the collar aligning the down-sized lug and notch.  Each of the shoulders is provided with a lower, lug-engaging, inclined surface which bears against its corresponding lug with progressively increasing force for fluid-tight sealing purposes as the plunger is rotated into a fully locked condition, there being abutments associated with the shoulders blocking movement of the lugs beyond positions corresponding to the fully locked and rotated position of the plunger.

Abstract: SELECTIVE CHEMICAL REMOVAL OF HARD SURFACE           COATINGS FROM SUPPERALLOY SUBSTRATES                       ABSTRACT     This invention consists of a chemical stripping composi-tion comprising an aqueous solution of H2SO4, a nitro-substituted aromatic compound, a fluoride ion producing species, and a surfac-tant, together with an accompanying method wherein the composition can selectively remove hard surface layers deposited through flame, plasma spray, and detonation gun techniques on superalloy substr-ates by contacting the above stripping solution in a heated bath wherein the bath is continuously agitated by an ultrasonic agitation means.              BACKGROUND OF THE INVENTION   This invention is related to the removal of ceramic, cermet and metallic coatings from high strength, high temperature re-sistant metal substrates and more particularly, to the removal of these hard surface coatings from superalloys, particularly nickel-base substrates by use of an aqueous acidic stripper bath equipped with a high energy density agitation means.   One of the most difficult requirements in the chemical stripping art has been to develop a composition which will chemi-cally remove the "hard surface" coatings, that is, molten particle coatings which are applied by detonation gun, plasma, and flame spray methods onto metal surfaces, such as the nickel-base jet engine combustion chambers.  Such coatings, which are usually applied in thin layers to provide protection against high temper-ature oxidative gas streams, include heat resistant ceramics, cermets, and nickel-base mixtures.

Abstract: Method And Apparatus for Treating Organic Wastewater Richard W. Heil, Clarendon Hills, IL and Thomas A. Rose, La Grange, IL            Abstract of the Disclosures A method and apparatus for treating a continuous stream of organic wastewater using highly concentrated activated sludge (10,000 mg/? MLSS), elevated atmospheric pressure, and high levels of dissolved oxygen.  The apparatus consists of three pressurized vessels linked in series by piping, and maintained at equal pressure by means of a common manifold.  The first vessel receives the mixed liquor consisting of macerated sewage and return activated sludge and thoroughly aerates it with diffused air bubbles.  The liquor then flows by gravity into the second pressurized vessel where flocculation and further aeration occur. From an overflow/transfer box in vessel 2, the liquor flows by gravity into the bottom tier of the third vessel which functions as a cyclone seperator.  The concentrate is drawn from the bottom of the vessel by a return sludge pump and recycled to the first vessel.  The centrate rises into the upper tier of the third vessel where it is clarified and discharged as tertiary quality effluent.

Abstract: FABRICATION OF CLEAVED SEMICONDUCTOR LASERS            Abstract A process is described for making semiconductor lasers with cleaved facets for end mirrors.  The process involves electrochemically photoetching slots with deep, narrow cross-sections in a wafer and applying stress to cleave the wafer in the desired place.  Extremely short and reproducible semiconductor lasers can be made by this procedure (less than 100, 50 or even 25 µm) which yields extremely useful semiconductor lasers particularly for communication applications.  Also, the procedure requires a minimum of skill to produce excellent quality cleaved semiconductor lasers (including short-length lasers) with high yields.
