Abstract: JOINT ASSEMBLIES BETWEEN     STRUCTURAL MEMBERS Abstract of the Disclosure A joint assembly between structural members having plate portions includes an eliptical opening through the plate portion of a first member and a notched locking plate portion on a second member.  The latter plate portion is in-troduced through the eliptical opening parallel to the major dimension thereof and is then rotated 90° to a locking position parallel to the minor dimension of the opening, whereby the notches interengage with the first plate portion to restrain separation of the two structural members.  Resilient spring clips are mounted on the first plate portion outwardly adjacent the eliptical opening in the direction of the minor dimension thereof to releaseably engage the second plate portion against rotation when the latter is moved to the locking position. In another embodiment, a composite beam is assembled from a plurality of structural members having plate portions provided with eliptical openings therethrough.  The structural members are interengaged with the plate portions in parallel juxtaposed relationship by means of a notched key plate introduced through the openings and rotated relative thereto in the foregoing manner for interengagement with spring fingers on one of the members.

Abstract: COMPACT, TRIPLE-HINGED AGRICULTURAL IMPLEMENT TOOL BAR                       ABSTRACT       A hydraulically actuated, triple-hinged tool bar comprised of four independently positioned sections is dis-closed.  A first outer section is flexibly coupled to one end of a center section of the tool bar while to the other end thereof is flexibly coupled an intermediate section, the length of which is less than that of the first outer section.          A second outer section is flexibly coupled to the outer end of the intermediate section providing a lower profile when all sections of the tool bar are in the retracted, or non working position.  Positioning control between the center section and the first outer and intermediate Sections is provided by respective hydraulically-actuated cylinders while a third hydraulic cylinder coupling the intermediate and second outer section dampens the vertical movement of the latter for in-creased stability in the working and non-working positions.          Spacers located between the canter and first outer sections and between the first and second outer sections provide for the proper positioning and stability of the various sections when retracted.

In the reaction the silyl amine groups have been replaced by alkoxide groups without significant loss of the silicon-hydrogen group.  Similar reactions in the absence of a catalyst give undesirably low yields of the corresponding alkoxy silanes and, in most cases, substantial loss of silyl hydrogen groups.

Abstract: LABEL DISPOSAL FILTER           ABSTRACT OF THE DISCLOSURE              An apparatus for separating loose p per pieces from a bath of caustic soda including a tank with a hopper-like structure disposed at the top of the tank. A helical screw conveyor is operatively disposed below the hopper and has its discharge exteriorly of the tank. A pair of perforated stain-less steel screen-type spaced rotatable drums is operatively disposed between the hopper and the conveyor, and a hollow stainless steel screen-type cylindrical filter (with a nylon filter cover) is positioned in the bottom of the tank and has an outlet extending to the tank exterior. In operation, a caustic soda solution mixed with paper pieces in the hopper is discharged by gravity onto the rotating drums which feed the paper pieces via the outer (rotating) drum surfaces into the con-veyor and thence to the exterior of the tank. The caustic soda solution flows through the perforations in the drums and thence to the bottom of the tank and through the cylindrical filter for final filtering and thence to the tank exterior.         The drums and filter have back flushing devices to clean the interiors thereof, A vertical screw conveyor is operatively secured to the discharge of the helical screw con-veyor for transporting the  paper pieces from the helical screw conveyor up above the apparatus and onto an associated conveyor chute. Brushes are selectively positioned in the apparatus to clean the exterior surfaces of the drums and filter.

Abstract: ABSTRACT OF THE DISCLOSURE       There is disclosed herein an ultrasonic imaging system for use in non-destructively testing objects, which system includes a source of ultrasonic energy, a liquid crystal detector cell and an optical viewing sys-tem.  The liquid crystal detector cell includes a pair of acoustically transmissive covers which encase a nema-tic liquid crystal material.  The material exhibits an acousto-optic effect, and in particular, exhibits bire-fringence in response to ultrasonic energy.  The cell construction, geometry, and material are acoustically matched to the frequencies of the insonifying ultrasonic transducer so as to optimize the performance of the cell. The covers are substantially acoustically transparent to ultrasonic energy incident on the cover at both normal and oblique attitudes.  The acoustic impedance of the covers match as closely as possible to that of the cou-pling medium.  The average alignment of the liquid crys-tal molecules, as indicated by the director, is selec-tively aligned to be oblique to the ultrasonic beam, and by reason thereof the cell exhibits high sensitivity and high image resolution in the "non-streaming" region. Electric field enhancement may be used to cooperate in aligning the liquid crystal molecules and to enhance the resolution and sensitivity of the image.

Abstract: ABSTRACT OF THE DISCLOSURE     A polyurethane RIM system has at least two molding stations.  The reactants are brought to the mixheads as three separate streams.  One stream contains the isocyanate, the second stream contains some of the polyol, the chain extender and crosslinker and a third stream contains additional amounts of the polyol, along with what additives might be desired.  At each mixhead the proportions of ingredients are controlled to give an isocyanate index of about 100, but the ratio of one polyol stream to the other is regulated to con-trol the flex modulus and other properties of the molded product as may be desired.  In this way, one source of supply can be used to feed several molding stations, each of which may produce a product of different physical properties and thus of different costs.

Abstract: ABSTRACT:                 In a cathode-ray tube having a glass envelope portion, a gettering device (18) is urges against an internal wall portion of the glass envelope portion (2) by means of a resilient metal strip (19) connected to a component of the tube.  The gettering device comprises a getter holder (30) in the form of an annular metal channel which is connected to the resilient metal strip (19) via a metal connection strip (32) and furthermore is kept spaced from the wall portion by a metal supporting construction (33).  The supporting construction is formed by a metal supporting arm (33) extending from the metal connection strip (32) which at its free end (34) is curved convexly with respect to the wall portion and contacts the wall portion in an area (35) situated centrally with respect to the annular channel (30).  This construction enables the temperature of the supporting construction at the area where it contacts the wall portion to be kept below 700°C during the inductive heating of the gettering device.  The occurrence of glass damage as a result of a thermal overload of the wall portion is thus prevented.

Abstract: A method and an apparatus for the dynamic and non-contact measurement of the distance separating the surface of a first part that may be conductive or not, from the surface of at least one second conductive part closely spaced from the first conductive part. The method resides in positioning, on the surface of the first part, at least one sensor including two conductive plates that are parallel, superimposed and electrically insulated from one another. The two plates of this at least one sensor are then fed with a same high frequency signal under the same voltage and the current generated by this high frequency signal, between the plate of the sensor which is closest to the surface of the second conductive part and this second conductive part, is measured. This measured current varying as an inverse function of the distance separating the surface of the second conductive part from the surface of the sensor which is closest to this second conductive part, it is then easy to determine the value of the distance separating the first and second conductive parts as a function of the value of the measured current. This method as well as the apparatus for carrying it out are particularly well adapted for measuring the air gap in any type of rotating machine such as an electric generator.
