Abstract: THIRD HARMONIC SIGNAL GENERATOR                Abstract of the Disclosure An integratable third harmonic signal generator includes a signal multiplier coupled to a source of alternating input signal, for providing a first output signal proportional to the input signal raised to the third power.  The first output signal includes a first harmonic component and a third harmonic component each proportional to the input signal.  Means are also included for deriving, from the input signal, a second output signal in predetermined magnitude and polarity relation with the first harmonic component.  The first and second output signals are combined to cancel the first harmonic component and thereby provide a third output signal pro-portional to the third harmonic component of the input signal substantially devoid of any first harmonic component.

Abstract: ABSTRACT OF THE DISCLOSURE            An improved method for manufacturing paper utilizing an improved Fourdrinier paper making machine, as well as an apparatus for improving the efficiency of the machine, while producing paper of improved quality.  The present invention overcomes the drawbacks associated with the conventional paper making machines in that the improved method and apparatus permits the use of a higher consis-tency of pulp stock supplied at the upstream end of the forming section of the machine, resulting in reduced water consumption and smaller pumps and associated piping.          The apparatus comprises shear means situated above an upper surface of a top run of a Fourdrinier fabric such that a lower portion of the shear means is adapted to penetrate a pulp stock web situated on the Fourdrinier fabric.  The shear means is operated by an external source of power, the source of power adapted to drive the shear means at a sur-face speed exceeding a linear speed of the fabric by greater than 3% and less than 8% of the speed of the fabric.  The shear means is situated at a location where a consistency of the pulp stock web situated on the fabric is between 2% and 5 1/2%; and the shear means adapted to provide a shearing action to fibre bundles and flocs situated in the pulp stock web as the pulp stock web passes between the shear means and the fabric, there re-working the pulp stock web and re-forming the fibre network and smearing the flocs thereof.

Abstract: ABSTRACT OF THE DISCLOSURE   This invention relates to a method for continuously producing a reinforced plastic pipe having a spigot fitting of the desired outside diameter and surface shape.  The method comprises helically winding an endless belt on a rotating mandrel, continuously winding a molding material impregnated with a thermosetting resin on the endless belt, continuously moving the molding material toward the tip of the mandrel together with the endless belt by the rotation of the mandrel, passing the moving molding material through a curing zone to cure the thermosetting resin, and then removing the molding material from the endless belt at the tip portion of the mandrel.  Prior to the introduction of the molding material into the curing zone, a split ring mold having an inside surface of a desired shape is mounted around the molding material so as to clamp the molding material tightly, thereby to convert the shape of the outside surface of the molding material into one corresponding to the shape of the inside surface of the split ring mold.  After the leaving of the molding material from the curing zone, the split ring mold is removed from the molding material, and that portion of the molding material on which the mold has been mounted is severed to provide a reinforced plastic pipe having a spigot element of a desired outside diameter and a desired outside surface shape.  The method of this invention is faster and less complicated than the known batchwise methods.

Abstract: Abstract A low cost cam controlled mechanical positioning apparatus for automatically tracing out a predetermined path of movement for the working head of a machine tool or the like is described.  The apparatus comprises a set of two large diameter disc type control-drive cams secured in parallel planes on a common drive shaft rotatably supported on a base member and driven by an electric motor through suitable gearing.  Respective cam followers engage cam surfaces formed on the undersides of the large diameter control-driven disc cams and are connected to respective linkages for trans-lating movement of the cam follower to a working head to thereby move the working head in a predetermined path of movement in an x-y plane.  A working head supporting boom is secured to a transport mechanism which is movably supported on wheel and track elements and mounted for movement along respective x and y axes by the respective linkages driven by the cam followers.  The plane of the x-y movement of the working head is parallel to the planes of the control-drive disc cams and the control-drive disc cams are supported on the base member in a position to overlie and inter-leave with the linkage and transport mechanism to thereby form a compact design.

Abstract: ABSTRACT OF THE DISCLOSURE      Banks of a green non-sulfide metal ore are formed along the inner surfaces of sidewalls of reverberatory furnace of green-charge type and are melted thereby to form slag and matte, a major portion of the matte being tapped out of the furnace, while a mixture of the slag and the remaind-er of the matte is introduced into a separation furnace to be completely separated.  During this process, an oxygen-containing gas is blown through lances, past the slag layer made thin by the tapping of the slag-matte mix-ture, and into the matte underlying the slag in the reverberatory furnace thereby to raise the copper content of the matte thus formed and, moreover, to increase the concentration of SO2 in the resulting exhaust gas.  By this method, the processing capacity of the reverberatory furnace is increased and, moreover, the load on a converter for further processing of the matte is reduced.  At the same time, the exhaust gas can be used directly, as it is, as a starting material for producing sulfuric acid.
