Abstract: ROTATING RECTIFIER ASSEMBLY                          Abstract A rotary rectifier assembly including a shaft adapted to be rotated.  Three equally angularly spaced phase conductors are disposed about the shaft and insulated with respect to each other and with respect to the shaft and each has opposed, axially opening recesses.          Diode wafers are received in each of the recesses and each recess further receives an electrically conductive load shoe.  A pair of end conductors sandwich the phase conductors, wafers and load shoes and each end conductor has three equally angularly spaced curved recesses for matingly receiving the curved portion of the corresponding ones of the load shoes.  A single biasing device is employed to bias one end conductor towards the other to thereby establish good electrical contact between the various components while occupying a minimum of space and minimizing the overall weight of the assembly.

Abstract: ABSTRACT OF THE DISCLOSURE      Nucleic acid hybridization assay methods and reagent systems for detecting a particular polynucleo-tide sequence in a test medium.  An aggregate is formed in the assay reaction mixture comprising intercalation complexes between a nucleic acid intercalator and double stranded nucleic acid associated with the hy-bridization product of the sequence to be detected and a nucleic acid probe sequence.  Hybridization of the probe with the sequence to be detected can then be determined by addition of an antibody, or a fragment thereof, capable of binding with the intercalation complexes in the formed aggregate and measuring the antibody or fragment thereof which becomes bound to such intercalation complexes associated with hybri-dized probe.  In one preferred embodiment, this method eliminates the need to chemically modify the probe in order to form a labeled reagent.  In another embodi-ment, the method provides an advantageous method for labeling the probe by chemical modification.     MS-1320-CIp-II

The sidewalls take the form of a relatively thin planar web in which the openings are formed and each web is formed with three horizontal, vertically spaced shelves projecting forwardly from the rear edge of each opening.  Stacking feet on the outer side of the web may be supported on a selected set of one of the three sets of shelves on an underlying like container, access to the two lower shelves being achieved by passing the feet of the upper container downwardly in the openings forwardly of the shelves.  The lowermost of the three shelves constitutes the bottom edge of the opening and the front end of the next uppermost shelf projects forwardly beyond the front end of the uppermost of the three shelves.

Abstract: ABSTRACT OF THE DISCLOSURE:         A carpet and pad installation avoids the need for stretching and tackless strips by utilizing a pad with pressure-sensitive adhesive on its upper and lower surfaces. The pad is first laid on the floor surface and trimmed as required, with its lower adhesive surface adhering to the floor.  Its upper  surface has  a  removable  release  film covering the pressure-sensitive adhesive,  permitting the carpet to be unrolled over the release film and then cut and seamed as required.  The seamed carpet is folded back and the release film is removed from the exposed area of the carpet cushion, then the carpet is pressed down onto the exposed area of adhesive.  Then another portion of the carpet is folded back, the release film is removed from that area, and that portion of the carpet is pressed onto the exposed pressure-sensitive adhesive of the carpet cushion.

Abstract: RAILWAY CONTAINER AND CAR         ABSTRACT         An improved container for bulk cargo is provided with a peripheral wall, a top, and a bottom. The top defines a longitudinally extending central ridge and the bottom defines two spaced, parallel, longitudinally extending skirts separated by a central recess.  The contour of the top generally corresponds to the contour of the bottom such that multiple containers can be stacked one over the other.  The container is provided with a perforated floor which simultaneously braces the peripheral wall against spreading and provides a support surface for palletized cargo and the like.  The floor perforations allow bulk cargo to fall from the upper portions of the container to the lower portions of the container.  A bulk cargo loading door is provided in the top along the uppermost portion of the central ridge, and two bulk unloading doors are provided along the lowermost portions of the skirts.  In addition, end doors are provided for moving palletized cargo into and out of the container.  The container of this invention can be transported on a railway car of the type having an elongated central spine shaped to fit within the central recess of the container. This railway car defines four container attachment struc-tures, each of which supports the container at a point well below the uppermost level of the spine.  In this way, the center of gravity of the container is kept low and close to the ground.

Abstract: "PROCESS AND APPARATUS FOR SLEEVE REPAIR OF PIPE LINE"                  ABSTRACT OF THE DISCLOSURE A longitudinally split  cylindrical sleeve, consisting of two half shells, is applied to an internally pressurized pipe, to reinforce a section of the pipe wall weakened by an internal or external defect. One pair of adjacent shell ends are first welded together along their length with the shells in place on the pipe in a relaxed condition.  The other pair of adjacent shell ends are equipped with longitudinally extending, outwardly projecting, attached shoulder lugs.  A clamp assembly is applied to the shoulder lugs to draw them together and tension the sleeve about the pipe.  The clamping force applied to the shoulder lugs is monitored and terminated when the applied stress in the sleeve is approximately equal to the stress exerted on the pipe wall by the internal fluid pressure.  The free ends of the shells are then welded together longitudinally while in the tensioned condition.  The sleeve/pipe combination forms, in effect, a thick-walled cylinder.  The stress arising from the internal fluid pressure is distributed across the cylinder.  This effectively lowers the stress at the location of the defect.  This, in turn, eliminates the need to apply circumferential fillet welds at the sleeve ends, since further deterioration of the defect (which would lead to leaking of the contained fluid) is arrested.

Abstract: ABSTRACT OF THE DISCLOSURE     A three-way valve for use in a fluid pulsation attenuator having a flexible diaphragm forming an interface with a flow of pulsating fluid on one side and a chamber of pressurized air on the other.  The valve includes a head and an attached sliding tube having a plurality of orifices through its wall.          As the head follows movement of the diaphragm, the sliding tube moves between positions which permit one or more orifices to communicate with chambers in the valve to either introduce additional pressurized air into the air chamber portion of the attenuator, or to discharge air therefrom, as needed, to quickly achieve matching, at start-up, and the continuance of matching of the air chamber pressure to the running-average pressure of the fluid on the other side of the diaphragm, and thus to keep the diaphragm's average position approxi-mately centered within its range of movement, ready to absorb pulses of either sign.
