Abstract: APPARATUS AND METHOD FOR TREATING AN AGGREGATE          MATERIAL WITH A FLOWING GAS            Abstract of the Disclosure Aggregate being directed into a rotary kiln (12) is preheated continuously and in a highly effective manner by directing the aggregate downwardly along a passageway (35) formed by a pair of gas permeable retaining walls (36) which extend generally vertically in opposing spaced relation to one another.  The retaining walls (36) are of a nonlinear zigzag configuration so arranged as to direct the thin layer of aggregate along a sinuous path of travel in the course of its downward movement along the elongate passageway (35) as heated gas from the kiln (12) is directed through the retaining walls (36) guiding the aggregate.

Abstract: ABSTRACT        A pressure responsive, variable resistance, analog device has at least one pair of first and second conductors in spaced-apart relationship.  A pressure sensitive resistive conductor composition is disposed in a position to interconnect a resistance between the first and second conductors when the resistive conductor composition makes contact with the conductors.  The amount of resistance so interconnected varies inversely to the amount of pressure exerted against the resistive composition.  The invention may be incorporated as part of a multiple touch switch having either a lateral or vertical configuration.  In addition, the invention may be configured as a pressure transducer device with or without a spacer between adjacent components of the device.

Abstract: COATING APPARATUS PROVIDED WITH                 A PROTECTIVE SHIELD     ABSTRACT OF THE DISCLOSURE         Coating apparatus for carrying out a process of coating in which one or more layers of coating com-position are applied to the surface of an object, such as a continuous web or discrete sections of sheet material, by advancing the object through a coating zone in which a flow of coating composition is applied thereto, for example, bead coating or curtain coating apparatus, is provided with a shield to protect the flow of coating composition against disturbance by ambient air currents.  The shield is formed of a fora-minous material, such as  screening or perforated plate material, which functions to diffuse air currents impinging thereon so that their velocity is decreased, with a resulting decrease in their ability to disturb the flow of coating composition.  Particular advantage is achieved in using the shield in processes for coat-ing photographic materials, especially in high speed curtain coating operations involving a substantial height of free fall, and in bead coating operations employing a slide hopper where ambient air currents give rise to a problem of differential evaporation of coating composition on the slide surface.

Abstract: METHOD AND APPARATUS FOR THE MANUFACTURE             OF WIRE LINK BANDS    ABSTRACT OF THE DISCLOSURE             A method and apparatus for manufacturing wire link bands, for example for use in paper making, are disclosed.  Several wire links or helices are arranged parallel to each other, adjacent helices having opposite pitch.  The helices are simultaneously fed through a closure slot while under tension.  The closure slot is so shaped as to cause each turn of each helix to be engaged between two adjacent turns of an adajcent helix, thereby to form a wire link band.  The closure slot may be held stationary while the wire links are pulled therethrough, or the wire links may be held stationary under tension while the closure slot is moved along their length.  A plurality of closure slots may be used to form several wire link bands in parallel, and at least one additional closure slot may then be used to combine the wire link bands into a larger wire link band or sieve.  Connecting rods may also be inserted into the wire link bands and may be heat fixed before insertion.

Abstract: Abstract of the Disclosure Proper alignment of threads when joints of casing are made up in hostile environments, such as on off-shore floating platforms subject to being buffeted by wave action, is provided the means of an improved box and pin connector.  The pin has a substantially tapered threaded section whose small diameter end terminates in a cylindrical lower guide section and whose large diameter is adjacent a larger diameter cylindrical upper guide section. A stop above the upper guide section is provided by an upset.  The box has a complementary section of internal oppositely tapered threads to mate with those on the pin as well as a smaller lower cylindrical receptacle to receive the lower guide section on the pin and a larger cylindrical receptacle to receive the upper guide section on the pin. The upper and lower guide sections on the pin and complementary receptacles in the box guide the threads into proper alignment.  The threads are sufficiently tapered so that the guide sections and comple-mentary receptacles are mutually, partially engaged prior to engagement of the threads.  The threads have a back slant that prevents expansion of the box.

Abstract: Abstract of the Disclosure A meat grinder includes a bone chip remover in which the bone chips are removed at a radially outer region of the grinding plate through a single tangential opening substantially in the plane of rotation of the knife in response to intermittent operation of a valve.  Knife blades which have substantial axial depth perpendicular to the plate are curved rearwardly to the direction of rotation, to apply an outward force component or pumping to chips which do not pass through the grinding plate, have terminal ends which sweep about a region radially outwardly of the perforated region of the plate, at a non-grinding or non-perforated region, behind which the chips are trapped and rotated about with the rotation of the knife blades for intermittent purging.  The knife is formed with relieved areas at the radially inner ends of the blades to provide a region of communication, adjacent the grinding plate, between successive blades to prevent the formation of a central stagnation region and provide that bone chips missed by one blade may be acted upon by another to move chips outwardly.         The grinding plate is supported in the cylinder and locked in place by an inwardly extending locking pin carried on a sleeve received within the cylinder engaging the front outer edge surface of the grinding plate.  The axial inward extension of the pin is less than the thickness of the plate, leaving the entire inside surface of the plate free of obstruction.  This allows the blade tips to reach into close proximity to the inner surface of the cylinder and provide a more positive action in forcing bone chips into the opening.  It also essentially seals off the area between adjacent blades to enable a pressure drop in that area when it is purged; with a consequent movement of collected bone chips from the relieved central region into the purged area for subsequent pickup and outward displacement by a blade.

Abstract: Apparatus and Method for Controlling Consistency Abstract Consistency of slurries such as paper pulp stock is controlled by ultrasonically measuring the flow of the slurry (the velocity of the particles therein) as the slurry is agitated by an impeller which induces circulation thereof within a region in a tank containing the slurry.  Dilutant is added under the control of the measurement and a mixed slurry of desired consistency is obtained, respectively at an inlet and an outlet in com-munication with the region of the tank where flow is being induced and measured.  Consistency control is obtained in the containing vessel or tank with greater accuracy and at lower cost than in apparatus where con-sistency is measured outside of the vessel containing the slurry.
