Abstract: ABSTRACT         A speaker verification system includes an input analyzer for analyzing a word spoken by a registered speaker or a person being verified, and outputting the result as an input pattern.  A registration number designator is provided for outputting a regis-tration number and an input pattern buffer is provided for storing the input pattern.  A verification reference pattern memory stores the input pattern as a verification reference pattern during regis-tration, designated by the registration number.  A control refer-ence pattern memory stores, as control reference patterns, patterns which are obtained when several predetermined persons speak a predetermined password.  A pattern matching unit is provided for determining first dissimilarities between the verification refer-ence pattern and the control reference patterns, a second dissimi-larity between the input pattern of the person being verified, which is obtained during the verification, and the verification reference pattern, and third dissimilarities between the input pattern and the control reference patterns.  A control reference pattern designator is provided for selecting several first dissimi-larities consecutively, starting from the smallest of the first dissimilarities, to designate the control reference patterns cor-responding to the selected dissimilarities as the control reference patterns corresponding to the registration number.  Finally, a judgement unit is provided for generating the confirmation signal when the second dissimilarity is less than both the third dissimi-larities corresponding to the designated control reference patterns and a predetermined threshold value.

Abstract: VALVE STEM PACKING ASSEMBLY                 (Abstract of the Disclosure) A valve body has a stem passage rotatably receiving a valve stem. A packing surrounds the stem in the passage and a packing nut threaded on the stem applies axial force to radially expand the packing into sealing engagement with the stem and passage wall.  The packing comprises cooperating first and second packing members engaging at an angularly disposed slippage surface for translation of compressive axial forces into radial expansion and sealing engagement with the stem and passage wall.  A packing support ring engages the end face of the packing adjacent the packing nut.          A gland engages the support ring and a pair of reversely positioned spring washers are interposed between the gland and packing nut.  A handle is attached to the stem by a handle nut, and a spring washer interposed between the handle and handle nut prevents loosening of the handle nut.  In an alternate embodiment of the invention, opposed packing support rings engage the opposed end faces of the first and second packing members.  The support rings include chevron surfaces for radially expanding the packing members and the support ring adjacent the packing nut includes notches in the chevron surface for gripping the packing member to prevent relative sliding movement therebetween.

Abstract: PULL-TYPE WINDROWER            ABSTRACT OF THE INVENTION   A pull-type swather or windrower which can be used either singly or in a duplex or tandem arrangement can be adjusted from a working position to a transport position by pivot-ing the hitch through 90° and by unlocking the wheels so they turn through 90° to move the swather at right angles to its working direction.  The swather is mounted on two wheels inwardly of the ends of the swather and rearwardly of the drapers with the wheel remote from the hitch movable to a position forwardly of its working position so as to lie under the drapers and to balance the centre of gra-vity so that the swather can be supported solely by the two wheels in the transport position.  A rear or duplex swather can be attached to the front swather by a duplex hitch which provides steering movements of the rear swather in a direction opposite to the steering movements of the front swather so that the former properly tracks the latter in echelon relationship.  The steering movements are ob-tained by a spring biassing the rear swather in one direc-tion and a flexible linkage arrangement which controls the amount of movement of the rear swather.  The intermediate hitch can be latched to the front swather to take up a transport position.

Abstract: ABSTRACT     This invention relates to a composition comprising a fluorochemical compound useful for treating leather, textiles, end cellulosic materials.  The invention also relates to a method for treating these materials with the composition.    Although there are many commercially available fluorochemicals which will impart water and oil repellancy to leather and textiles, they are generally applied from solutions wherein the solvent is a chlorinated hydrocarbon, e.g., trichloroethane.  These solvents are often deleterious to leather and dyes that have been applied to leather.  Many consumers find chlorinated hydrocarbons objectionable for both health and environmental reasons.          This invention provides compositions containing a fluorochemical compound which confer durable water and oil repellancy to leather and textiles while not adversely affecting the appearance, feel, hand and other desirable qualities of the leather and textiles.  The fluorochemical compounds useful in the practice of this invention are capable of providing up to about 30 times as much water repellancy to leather as the best commercially available leather treatment products.          Fluorochemical compounds useful in this invention contain (a)  a fluoroaliphatic moiety, (b)  an aliphatic moiety, and (c)  an organic group which connects moiety (a) and moiety (b). The preferred fluorochemical compounds contain one or more sites of unsaturation, which allows crosslinking after they are applied to the surface of the leather or textiles.          The fluorochemical compounds of this invention can be applied from solvents that are not harmful to the health of the consumer, to leather itself, to dyes previously applied to leather, or to textiles and cellulosic materials.

Abstract: NOVEL PUMP AND SYSTEM EMPLOYING SAID PUMP                 ABSTRACT OF THE DISCLOSURE      A system is provided for delivering controlled quanti-ties of a steady stream of a fluid to an application zone. The system includes a positive displacement pump for produc-ing uniform pulses of small quantities of said fluid.  The pump has a piston housing with an elongated bore extending from a first open end to a position proximate a second closed end and a pumping chamber region at said  second end. The pumping chamber is provided with a pumping fluid inlet and a pumping fluid outlet. A reciprocating and rotating piston, is positioned for rotational and reciprocating motion within said elongated bore of said piston housing, from a first position in which said piston substantially occupies the space within said pumping chamber and displaces pumping fluid from said pumping chamber to a second position in which said piston is substantially removed from said pumping chamber and draws pumping fluid into said chamber. A barrier fluid inlet means is provided at a position which is between said elongated bore first end and said pumping chamber and adjacent said piston.  Barrier fluid is delivered to the elongated bore at a pressure which is greater than the maximum fluid pressure within said pumping chamber, in order to produce a positive pressure differ-ential which precludes migration of pumping fluid from said pumping chamber, along the piston, to said first open end. A mixing chamber is provided for mixing pumped fluid with air.  The mixture is delivered to an application zone through an elongated restricted flow conduit, whereby said fluid and said air transform from a pulsed flow at said flow conduit first end to a steady flow at said second end.
