Abstract: Abstract of the Disclosure A thermal printing device comprises a continuous bar of electrically resistive material, on a substrate, with first and second patterns of electrical conductors, a pattern on each side of the bar.  Connections are made to the bar from the conductor patterns at closely spaced positions.  Application of electrical power to the bar at preselected position, via the conductor patterns and connections, produces localized hot spots.  The power can be pulsed, and very close spacing of connections to the bar can be provided.  By forming the conductor patterns as columns on one side of the bar and as rows on the other side it is possible to provide connections between columns and bar and rows and bar such that the number of external connections is minimized.  The conductor patterns, connections and resistive bar can be formed by various methods, for example, thick and/or thin film techniques, and evaporating.  The bar can extend the full width of a page, i.e. 8 1/2 inches, on a single substrate.                             - i -

Abstract: COPPER COATED, IRON-CARBON EUTECTIC ALLOY POWDERS       ABSTRACT OF THE DISCLOSURE         A mechanical mixture of selected powders is subjected to compressive forces to define a pre-compact, the pre-compact then being subjected to liquid phase sinter-ing for producing a raw alloy steel product which is more economical and has enhanced physical properties, particularly tensile strength as compared to sintered compacts produced by the prior art to date.  The improvement in physical properties and processing technique results principally from the use of a mechanical mixture consisting of a base iron powder and a coated alloyed additive powder having selected alloying ingredients (such as manganese, nickel, molybdenum, in an iron-carbon system); the particles of the alloyed powder have a thin flash coating of a low melting metal, such as copper, to control carbon diffusion into the base iron powder during liquid phase sintering.

Abstract: ABSTRACT OF THE DISCLOSURE             A suspension ceiling system having a novel and improved connector system is disclosed.  Such connector system includes a pair of similar end connectors which are installed in a single slot opening by straight-in movement with the connectors in side-by-side engaging relationship.  Each connector provides two pairs of opposed surfaces extending perpendicular to the length thereof, which interengage with mating surfaces on the other connector to positively lock the connectors together in a predetermined position and to prevent relative axial movement toward or away from each other from such predetermined position.  Each connector also provides a laterally extending tab which operates to secure a single connector within the slot opening prior to the insertion of the second connector and during such insertion.        Such lateral tab also prevents insertion of the second connector on the wrong side of the first connector.  In a second embodiment the connectors are formed with a tongue and socket structure which interfit when unusual conditions occur such as earth-quakes or the like.  This interfitting structure enables the connection to withstand much higher separating forces.  With the illustrated connectors, ease of assembly is achieved and the position of the connected parts is not adversely affected by variations in the thickness of the web containing the opening through which the connectors are assembled.

Abstract: FUEL INDUCTION SYSTEM             ABSTRACT OF THE DISCLOSURE         This invention relates to an improvement in the induction system of an internal combustion engine.  More particularly, the invention comprises an improved com-bination with or addition to an induction system wherein the primary barrel of a carburetor releases a fuel-air mixture to an intermediate conditioning chamber, which in turn is connected to deliver the conditioned fuel-air mixture to the usual intake passage or manifold.           Of recent years there has been a trend toward operating spark-ignited internal combustion engines at leaner air/fuel ratios in order to decrease the amount of hydrocarbon and carbon monoxide in the exhaust.  One limiting factor in going towards leaner operation is gasoline maldistribution from cylinder-to-cylinder.  The induced air/fuel ratio must be kept lean enough such that the cylinder supplied with the leanest mixture will still fire, otherwise exhaust hydrocarbon and carbon monoxide emission will increase rather than decrease.            In our earlier Canadian applications Serial No. 218,950 and Serial No. 218,951, we have described fuel in-duction systems for and in combination with multicylinder engines in which fuel maldistribution is substantially lowered.  In said system a container is provided in the exhaust gas flow path.  The carburetor barrel, or venturi, delivers an air/fuel mixture directly into this container in which it is heated and subjected to great turbulence forming a uniform air/fuel mixture.  This uniform air/ fuel mixture is then conducted into the intake manifold and thence into the individual cylinders.
