Abstract: Abstract of the Disclosure The invention involves a cell which may be used for producing molten aluminum by electrolysis of aluminum oxide in a molten bath.  The cell includes a cathode and an anode, a bar and a hanger.  The bar is connected at an upper end to the hanger and at a lower end to the anode.   Flexible means is provided for supplying electrical current through the bar to the anode.  A jack means raises and lowers the hanger and thus the anode.   Included in the invention, the hanger is mounted at at least two separated points, one higher than the other, in encompassing, sliding relationship, on a single, upright, circular cross-sectioned post passing through the hanger.   By this technique, the hanger is constrained to move up and down, without rotation about horizontal axes.          The invention additionally involves a clamp including means for providing a backing against which articles to be clamped can be placed, gate means mounted for pivoting about an axis into and out of confrontation with the backing means, the pivot axis passing through the gate means, and means for forcing the gate means toward the backing means at least when the gate means is in confrontation with the backing means. Included in the invention, at least the portion of the gate means at said axis moves toward the backing means during operation of the forcing means in forcing the gate means toward the backing means.          Also provided is a tool capable of operating such a clamp.  The tool includes a means for operating the forcing means and a means for pivoting the gate means.

Abstract: BCF: jg SHEET METAL BRAKE                 Abstract of the Disclosure A sheet metal brake comprising a frame, a member on the frame having a clamping surface, and a movable anvil having a clamping surface movable between workpiece clamping and non-clamping positions relative to the clamping surface.  A bending member is hinged to the clamping member.  An extension member is mounted on the anvil member and has a portion defining the clamp-ing surface.  The anvil member has its front edge spaced rearwardly of the front edge of the member on the frame which has a clamping surface.  The portion of the exten-sion member defining the clamping surface extends beyond the front edge of the anvil member and the area above and in front of the front edge is unobstructed such that the sheet can be bent substantially beyond ninety degrees.          An extension member is mounted on the anvil.  The extension member has a portion extending along a flat surface of the anvil to define a clamping surface, which portion extends beyond the front edge of the flat surface of the anvil such that the area above the free edge is unobstructed to permit bending a sheet substantially greater than ninety degrees.

Abstract: CABLE CONNECTOR HAVING A TAPERED          SLEEVE INSERT WITH AN EXTENSION          FOR LARGE DIAMETER, METALLIC           SHEATHED CABLE     ABSTRACT OF THE DISCLOSURE    A cable connector of universal design for attaching to the end of a scroll-type metallic cable sheath, the universal part thereof being a replaceable tapered sleeve insert with an extension.  Sleeve inserts of a non-complex design are provided over a wide range of sizes and scroll configurations, each of such inserts accommodating to a range of pitch scroll configurations and accommodating to a common connector or terminator body.  The extension of the sleeve permit filling with appropriate compound for explosion-proofing the connector.  A compression gland fits with the entrance sleeve face and with the entrance connector body face so that when the gland nut is tightened the sleeve insert is seated and the cable is held by the compression gland. The use of the sleeve insert also eliminates the need for a union part of the connector that would otherwise be used for some installations.  The range of pitch scroll configuration accommodation is provided by flat shallow turns in the screw. inserts.

Abstract: ABSTRACT OF THE DISCLOSURE     A novel process is provided for the formation of improved fibrous materials (primarily of acrylonitrile units) with increased modulus of elasticity and strength as well as decreased diameter.  Preferably, the material is acrylonitrile, typically copolymerized with a minor amount of an acrylic monomer such as methyl acrylate.  Oxidation of the fiber is effected at an elevated temperature in the presence of a car-boxylic acid, other than formic acid, or its anhydride within the fiber.  It is believed that the acid  and/or its anhydride which is formed at the oxidizing temperature serves as a plasticizer and reduces the fiber yield stress and increases fiber plasticity so that the fibers may be drawn by as much as 300% or more in the presence of the acid and/or its anhydride during oxidation, thereby providing the desired improvement in increased elasticity and strength.

Abstract: A B S T R A C T            The oil-in-water emulsion contains, besides the usual comp-onents, xylitol and sorbitol to inhibit water staining. The inhibitor is fully effective even when 1000 parts by weight of the emulsion contain only 1-30 parts by weight each of xylitol and sorbitol.     By making this addition of inhibitor the reaction of the water phase with the metal surface freshly created by roll-ing is to a large degree eliminated and with that also the formation of undesireable water stains on the surface of the strip.

Abstract: ABSTRACT OF THE DISCLOSURE             A web of flattened, tubular, heat-sealable bag material travels above and at the speed of a moving belt. Above the belt is a seal shaft which rotates a heated seal bar.  The working edge of the seal bar may be adjusted inward and outward relative to its shaft.  The edge causes a transverse seal to be made on the web at intervals.  A rotary perforating knife is driven at the same speed as the seal shaft and, at a subsequent station; perforates the web proximate the seal. The linear speed of the edge of the seal bar is at the speed of the belt at the time of sealing contact (about 65°).  The speed of the seal shaft for the remaining 295° is adjustable and thereby the distance between seals and perforations is adjustable.

Abstract: ABSTRACT OF THE DISCLOSURE            A method to control the burning of liquor varying in its chemical consistency at the recovery boiler is disclosed. Considering the burning, for accomplishing the suitable size of the droplet in the recovery boiler, the viscosity of liquor will be controlled on the basis of density measurement, which, however, has proved to be an unreliable and slow way.            To overcome these disadvantages the feeding parameters are controlled directly on the basis of the measured viscosity of liquor.

Abstract: ABSTRACT The invention relates to apparatus for analyzing electrical circuit boards.  Individual elements which have failed can be identified without dis-connecting them from the circuit and testing may be done by unskilled operators by contacting a probe to a lead on an element.  The probe has at least two contact elements close enough to each other to simultaneously contact a lead of a mounted integrated circuit, but spaced apart from each other sufficiently to permit measurement of electrical activity in the lead segment between the tips.  Circuitry is connected to the probe for measuring the voltage drop between the two tips resulting from the flow of test current through the resis-tance of the lead segment, which current flow is indicative of the condition of the element.
