Abstract: ABSTRACT OF THE DISCLOSURE         Industrial waters containing dissolved or suspended contaminants are treated by turbulently mixing the contaminated water with a composition comprising a discontinuous phase of gas in the form of surfactant-stabilized spherical bubbles having a narrowly distributed size in the range of from about 12 to about 100 microns and a half-life of at least about 2 minutes, each gas bubble being encapsulated in a double surfaced hydration layer containing water and a soluble surfactant having a HLB ratio greater than about 10.  The encapsulated gas bubbles are dispersed in a continuous water phase and each has an outer surface layer of collector ions movably held to the hydration layer by Coulomb forces and active to react with the contaminants.  The surfactant is present in an amount up to about 3 times critical micelle concentration so as to stabilize the bubbles and impart to the hydration layer sufficient thickness and viscosity to retard migration of the collector ions through the hydration layer for a period of time sufficient to enable the collector ions to react with the contaminants and cause nucleation thereof directly at the surface layers of the bubbles.  The reaction between the collector ions and the contaminants causes the bubbles to rupture and to release their entrapped gas as naked gas bubbles and forms an insoluble reaction product, the ruptured bubbles exposing the surfactant contained in the respective hydration layer thereof for reaction with any unreacted collector ions to form a further insoluble reaction product.          Both these reactions products are then allowed to separate from the water as a recoverable agglomerated material.

Abstract: CYLINDER LOCK AND KEY     ABSTRACT      A lock of the cylinder type having a plurality of discs forming part of the barrel assembly and being rotatable relative to one another and to the body of the barrel assembly.  The rotational axis of each disc is substantially coincident with the rotational axis of the complete barrel assembly and each disc has a keyway forming opening which contains that axis.  Locking means such as a side locking bar is operative to hold the barrel assembly against rotation relative to the lock cylinder, but that locking means is responsive to the rotational positioning of the discs to release the barrel assembly for rotation when the discs have a particular rotational position relative to one another.  The barrel assembly can be rotated in either direction away from the normally locked condition.  A key for use with such a lock has an elongate blade which is of non-circular cross section and is twisted to create a plurality of relatively angularly disposed locating portions which are spaced apart longitudinally of the blade.  Each locating portion is adapted to cooperate with a respective disc to hold that disc in the aforementioned particular rotational position.  The hand of twist is reversed at least once along the blade length and sloping camming surfaces on the blade promote radial movement of the discs as the blade is moved through the lock keyway.

Abstract: ABSTRACT OF THE INVENTION      Low energy demand structure with side walls, roof, and foun-dation is disclosed wherein the side walls have inner and outer structures, the outer structure of frame construction with very heavy insulation substantially filling the outer structure.  The inner surface of the outer wall structure is provided with a panel cover to hold the insulation in place and over the panel a moisture impermeable seal is placed.  The inner wall structure is of vertical frame construction and provides circulating air pas-sages and a finish interior surface.  The ceiling is of similar structure with the circulating air passages of the ceiling and walls in communication with each other.  The upper portion of the structure rests on foundation walls which extend at least 3 - 4' below the frost line and which are faced with rigid foam insula-tion also extending 3 - 4' below the frost line.  A lowermost floor slab of concrete, which is usually the basement floor, has circulating air passages formed therein which are in communica-tion with the air passages of the side walls or inner basement walls which, if present, are of hollow construction with air passages therein and the inner and outer basement walls are sepa-rated by a moisture impermeable vinyl sheeting and similar sheet-ing is placed between the floor slab and the underlying earth mass.  The lowermost slab is in conductive thermal contact with the earth mass which serves to maintain the temperature of the interior of the structure between 68-70° F due to the flow of thermal energy between the earth and slab and the flow from the slab by convetion to the air circulating through the passages in the slab wall and roof.  Preferably, auxillary blowers are uti-lized to insure positive circulation of the heating or cooling air in the passages.  Miniature heat pump units may also be uti-lized and located within the outer wall structure for coupling to the air passageways and outdoors.

Abstract: MATRIX CHARACTER PREPROCESSING SYSTEM            Abstract of the Disclosure A system for processing data used by a recog-nition system in recognizing an unknown character.  A multi-channel read member generates a plurality of parallel rows of data bits which taken together form an image of the character to be recognized.  In order to align the rows of data in their proper relationship, each row of data bits is examined to determine if the row contains data representing a feature characteristic of the unknown character or a clear channel.  The top row of the character is selected as the first row of data bits representing a feature characteristic of the character which follows the largest number of consecu-tive clear channel rows.  The top two rows of the charac-ter are then compared.  The row having the greatest number of feature characteristic data bits is selected as the top row of the character.  Signals identifying the top row of the character are generated for us by a recognition apparatus in recognizing the unknown char-acter from the rows of data bits generated.
