Abstract: ABSTRACT OF THE DISCLOSURE                The choker ring has a ring-like body having elements forming a primary aperture defining a primary axis along which a straight mainline cable loosely reeved there-through can extend with the primary aperture serving, in use, to confine the mainline cable therein. The body includes further elements forming a pair of parallel, co-extensive and adjacent secondary apertures which define respective secondary axes extending generally normal to and generally co-planar with the primary axis defined by the primary aperture.          A loop of a choker cable can extend through the secondary apertures in guided and confined relation therewith. Portions of the further elements which form the secondary apertures also define a pair of shoulders. Each shoulder is associated with a respective one of the secondary aperture and they project away from each other in opposite directions generally along a further axis which is co-planar with the primary axis and the secondary axes and is generally parallel to the primary axis defined by the primary aperture. The further elements which form the secondary apertures are arranged such that the secondary apertures are spaced apart generally along the further axis. The further elements which form the secondary apertures including an intermediate leg extending generally at right angles to the further axis between the secondary apertures and define a still further axis which is normal to the primary axis. A limited degree of rotation of a loop of the choker cable can take place about the intermediate leg. Each one of the pair of shoulders includes a surface portion facing inwardly of and defining a portion of its respectively associated secondary aperture. These surface portions form stops which serve to limit the degree or rotation of a loop of choker cable about the still further axis.

Abstract: ABSTRACT OF THE DISCLOSURE:         A resistance roll-welding machine for welding work-pieces moving in a predetermined feed direction, comprising two superimposed electrode rolls to which there is delivered welding current by means of a device for transmitting current from a stationary part to a rotating part.  One of the electrode rolls is mounted at a pivotably movable overhang arm or cantilever.          The overhang arm, at which there is pivotably mounted the one electrode roll, extends essentially transversely with respect to the feed direction of the workpieces and is pivotable about a pivot shaft extending in spaced relationship from said one electrode roll and transversely to the axis of rotation thereof.          The overhang arm or cantilever comprises a housing mounted in the machine frame to be pivotable about said pivot shaft and a shaft member which is rotatably mounted in the housing.  The shaft member has a free end which carries the one electrode roll.  The housing forms the stationary part and the shaft the rotating part of the device for the current transmission.

Abstract: DYNAMIC BLENDING WITH A SPRING-APPLIED FLUID PRESSURE RELEASED SERVICE BRAKE INCLUDING COJOINT SPRING AND FLUID PRESSURE EMERGENCY FEATURE     ABSTRACT OF THE DISCLOSURE       This invention relates to a vehicle brake apparatus wherein a service brake application is effected by a spring in response to the reduction of the pressure of fluid in a first chamber on one side of a brake-applying piston, and an emergency brake application is effected by the establishment of a fluid pressure in a second chamber on the other side of this piston whereby this other side of the piston is subject simultaneously to both the fluid pressure force thus established and the force of the above-mentioned spring.  A brake control valve device that includes a pair of self-lapping valve devices which respectively control the degree of reduction of the pressure of the fluid in the first  chamber and the degree of pressure of fluid established in the second chamber, also comprises a spring-biased lever having a fulcrum adjustable according to the load on the vehicle and an operator-controlled means for rendering the spring-biased lever operable to so effect operation of the pair of self-lapping valve devices as to selectively effect a service or an emergency brake application and a subsequent brake release.

Abstract: MOUTHPIECE WITH A TONGUE RETRACTOR   ABSTRACT           A mouthpiece comprising a tubular member about which a person may voluntarily place his lips in an air-tight manner for preventing a passage of air between the lips and the mouth-piece, said tubular member having a principal and a side air passageway and a blade-like member extending from one edge thereof, forming a tongue retractor for restricting the move-ment of the person's tongue and preventing it from obstructing a flow of air through the principal air passageway, is described.          For evaluating respiratory processes, the cross-sectional area of the principal air passageway of the tubular member is large enough so as not to significantly affect the then current physiology of the respiratory process being evaluated.  For use in administering medication, there is provided, in the interior wall of the mouthpiece, means, such as vanes or gun-barrel rifling, for controlling the air flow therethrough to the throat areas.  To accommodate different sized mouths, the tongue retractor is adjustable in size and shape so as not to elicit significant gag reflex from the tongue or soft palate of the person using the mouthpiece and to fit comfortably between the interior edges of the person's teeth and gums along the right and left sides of the lower jaw.

Abstract: ABSTRACT OF THE DISCLOSURE An endless power transmission belt and method for producing the same, are provided herein.  The belt has a portion which has a plurality of spaced belt elements defined by alternating projections and recesses with each of the elements having an outer part and a root.  A triaxial fabric which is defined by three angularly disposed sets of parallel courses of yarn interwoven substantially to prevent slippage of at least one yarn course set along any other yarn course set is bonded against the elements and defines all abrasion-resistant exposed surface of the elements.  The tri-axial fabric also minimizes shearing stresses in the element due to improved tear resistance thereof.

Abstract: METHOD AND APPARATUS FOR MIXING GASEOUS OXIDANT   AND LIXIVIANT IN AN IN SITU LEACH OPERATION            F-9457     Abstract of the Disclosure Method and apparatus for mixing a gaseous oxidant (e.g., oxygen) and a lixiviant (e.g., an aqueous carbonate solution) at a downhole location in a well before the oxygen-saturated lixiviant is injected into a formation to be leached. The invention involves establishing a mixing zone in the well by positioning an orifice plate in the well at the downhole location. Lixiviant as it is flowed down the well passes through a restrictive opening in the plate causing a substan-tial increase in the flow velocity of the lixiviant.  At the same time, gaseous oxidant is supplied to a point adjacent the opening in the plate and due to the increased velocity of the lixiviant flowing through the orifice, the oxidant is trapped to form a gas pocket below the orifice.  Lixiviant flows through the gas pocket and becomes saturated with the gaseous oxidant.

Abstract: ABSTRACT OF THE DISCLOSURE     A segmented damper is provided with a lower dovetail portion which is insertable into a dovetail slot for radial retention and which is engageable on its face by a blade retainer for axial retention, such that the damper is pivotable in an axial plane. The damper upper portion has on its one side a flange for engaging the blade shank rail and on its other side a flange for shifting the damper center of gravity axially outward from the lower pivot point.          Centrifugal force, occasioned by rotation of the disk and damper, then causes the damper to pivot and impart an axial force against the blade to thereby dampen vibrations.

Abstract: ABSTRACT OF THE INVENTION         The present invention is directed to an auto-matic leaf distribution system for use on a tobacco harvester.  The system incorporates an air stream to intermix with leaves being discharged from a supply conveyor and move the leaves towards a storage con-tainer.  The boundaries of the air stream are at least partially defined and the path of the air stream is changed by a leaf directing member to distribute leaves throughout a supported container.  The position of the leaf directing member is controlled to assure an efficient leaf distribution.  The use of air has greatly simplified the mechanics of the system and reduces the probability of leaf damage.  The system can easily be adjusted for various on site conditions assuring effective distribution of leaves within a sup-ported container.
