Abstract: LAMINATED EDGE CONTROL DEVICE            ABSTRACT OF THE DISCLOSURE           An edge control apparatus for trimming the excess plastic film that projects laterally from the edge of a backing material in a calendering operation, comprising a cutting tool, at least two signal producing sensing devices positioned on each side of the tool and mounted on a moveable support containing the cutting tool such that the edge of the backing can be accurately tracked after lamination but just prior to the laminating material traversing the cutting tool.  The disclosed apparatus allows for improved accuracy in tracking the edge of the backing material and, therefore, provides a more accurate means for removing the projecting plastic film for reuse without removing the backing material.

Abstract: ABSTRACT A manually operated valve has a housing with a uniform outside diameter compatible with the outside diameter of flow conductors attached to the valve.  An operating sleeve is movable longitudinally within the housing by engagement with a shifting tool from the exterior of the housing.  The operating sleeve shifts the valve between its open and closed positions.  A detent spring is provided to give an indication when the shifting tool has moved the operating sleeve sufficiently to fully open or close the valve.  The valve is particularly adapted for using in a drill string or workover string in an oil or gas well.

Abstract: ABSTRACT OF THE DISCLOSURE           Broadly stated, the present invention comprises: fluxing an isotropic carbonaceous pitch thereby rendering the pitch fluid.  Next, the fluxed pitch is introduced into a heating zone (vessel 2 of Figure 2) where the temperature is maintained in the range of from about 350°C to about 450°C, thereby resulting in the heat-soaking of the fluxed pitch. In a continuous process, at least some of the fluxed pitch is simultaneously removed or drawn off from the heating zone (2) and transferred to a cooling zone (6).  The temperature in the cooling zone generally ranges from above the freezing point of the fluxed pitch to below the temperature in the heating zone, and in a particularly preferred embodiment is maintained at the boiling point of the organic liquid used to flux the pitch.  Any solids suspended in the fluxed pitch after heat soaking and cooling are removed by filtering (zone 14) or the like.  Thereafter, the fluxed, heat soaked pitch is treated with an anti-solvent compound (zone 17) so as to precipitate at least a portion of the pitch free of quinoline insoluble solids.

Abstract: PUFFED SOFT MOIST PET FOOD PRODUCT HAVING AN EXPANDED SHELL WITH A DENSE CENTER       AND PROCESS OF PRODUCING THE SAME                Abstract of the Disclosure This invention relates to a soft moist pet food product comprising particles having an expanded shell with a dense, elastic structure in the center of the product and a process for producing the same.  The product is formulated from a proteinaceous-farinaceous mixture having a level of farinaceous component of at least about 40% by weight of the pet food product, typically 60 to 85% by weight of the pet food product.  The moisture content is adjusted to a level sufficient to extrude the mixture and extruded under conditions of elevated temperature and pressure sufficient to convert the mixture to a thermoplastic or flowable state.  The mixture while in a flowable condition is extruded through a restricted orifice into a confinement zone and confined while in a flowable state.  The mixture in this condition is injected into a com-pression zone wherein the mixture is cooled to a product tem-perature of about 100 - 180°F, compressed and formed into a product having a dense elastic structure.  The dense product is then heated wherein the exterior surface of the product is expanded to provide a product of reduced bulk density having an expanded shell but retaining a dense elastic interior.

Abstract: ABSTRACT         An electrochemical bipolar reactor has numerous conductive particles held in a fixed relationship to one another with non-conductive material wedged between at least some of the particles to electrically insulate those particles from other particles.  In one embodiment, the conductive particles are separated into discrete layers by layers of non-conductive material.          In another embodiment, the conductive particles are each partially covered with a layer of non-conductive material.  In either case, the non-conductive material is pervious so that electrolyte can readily contact the conductive particles.  The reactor has a relatively low void volume and current leakage is minimized.  In previous reactors with a higher void volume, the current leakage is greater.  The reactor of the present invention is particularly suited to process high volume wastes and can be constructed easily without machine parts.  Also, the reactor can be operated over a wide range of conditions.

Abstract: ABSTRACT OF THE DISCLOSURE     In metallurgical furnaces, the area of the furnace wall which comes into contact with the molten slag is exposed to special stress.  According to the present invention, this area of the furnace wall comprises a plurality of plate-like cooling elements arranged horizontally one above the other, through which cooling water flows, at least four of the said superimposed elements, for example, being secured detachably to a common cooling plate carrier supported in turn by a stationary support structure.  Adjacent cooling element carriers comprise a sheet steel housing, are adapted to pivot outwardly out of the furnace wall after the manner of a door upon hinges.          When repairs are necessary, the slag is tapped off and the relevant cooling element is swung out from the furnace wall on its hinge, after the support has been released.  The plate-like cooling elements now instantly accessible individually, secured detachably to the cooling element carrier and made of copper may now be simply and rapidly replaced while the furnace is still hot.  This reduces to a minimum the down time needed for repairs to the cooling elements of the pyrometallurgical furnace installation.
