Abstract: ABSTRACT OF THE DISCLOSURE      A paper winder assembly of the type in which a rider roll is positioned to bear against a roll on which the traveling paper web is being wound.  The rider roll position is controlled by hydraulically actuated lifting means which vary the pressure at which the rider roll bears against the paper roll.   In accordance with the present invention, there is included a pressure modulating valve which converts air pressure signals to hydraulic signals which operate the hydraulically actuated lifting means.  The valve includes a pair of flexible diaphragms therein with means to introduce air under pressure on opposite sides of the two diaphragms depending upon whether the rider roll is to be raised or lowered.  The valve has a spool actuator therein which is movable in response to the movement of either of the diaphragms. A spring means biases the spool downward and establishes fluid communication between an inlet port and an outlet port for transmitting hydraulic  fluid to the hydraulically actuated lifting means.  A feedback is provided in the valve body so that fluid pressure acts on the spool in opposition to the spring biasing force and eventually establishes an equilibrium position.  When the back pressure of the hydraulic lifting system is sufficiently high, the spool is positioned in vlave closing relationship, and excess hydraulic fluid is passed to a drain.

Abstract: Abstract of the Disclosure A technique is provided for assaying the formations surrounding a borehole for uranium-bearing ore.  A borehole logging tool employs a pulsed neutron source to cyclically irradiate the formations with neutrons.  The tool measures neutron fluxes produced during the period of time that prompt neutrons are being produced by the neutron fission of uranium in the formations.  The tool also measures the total neutron fluxes produced in response to each burst of the neutron source, such measurements being utilized to correct the neutron flux response of the borehole logging tool during the prompt fission neutron period for the effects of epithermal/thermal neutron moderation, scattering, and absorption within the borehole itself.

Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus and method for winding a multistrand roving package by guiding a plurality of strands along conver-gent paths of travel towards a winding mandrel employ a pair of spaced strand guide members in the vicinity of the mandrel.          The guide members define a gap for the strands and are recipro-cated parallel to the mandrel axis so as to alternately en-gage and deflect the strands into a side-by-side relationship in the package.  The strand guide members each have strand guide edge portions so located that, transversely of the mandrel axis, they are offset towards the mandrel from a linearly disposed relationship to intersect the strand paths at different res-pective angles corresponding to the differences in direction of the strand paths, thereby to compensate for differences in the strand deflections resulting from the differences in direction of the strand paths and to improve the strand deposition.

Abstract: WINDOW REPLACEMENT SYSTEM Abstract of the Disclosure A new and improved method and apparatus for replacing old windows in an existing building with new windows and surrounding trim comprises the use of elongated, especially designed trim elements which are cut to length and assembled onto the replacement window frame to trim the periphery thereof. The replacement window frame with the peripheral trim elements bodily attached thereto is then mounted in the opening in the building wall structure to replace an old deteriorated window previously removed there-from.  The novel method of assembly and installation guarantees a good fit between the trim elements and the window frame, and permits the critical seal between the trim elements and the window frame to be formed at a convenient location during the assembly of the trim elements onto the window rather than requiring a trim seal to be effected after the window is installed in the building.

Abstract: ABSTRACT OF THE DISCLOSURE       A tree-processing unit is disclosed.  The unit comprises a tubular member detachably secured to the boom support of a conventional motorized equipment, an elongated boom extending through both ends of the tubular member, guide means located within the tubular member for guiding and supporting the boom through the tubular member, and hydraulically-operated means mounted on the tubular member and on the front end of the boom for gripping and delimbing a felled tree.  In accordance with one feature of the present invention, the hydraulic lines interconnecting the hydraulically-operated means located at the front end of the boom and the tubular member, are maintained in a tight condition all the time to prevent tangling of the lines with the equipment and other obstacles on the working site.  In accordance with a second feature of the present invention, the guide means located within the tubular member includes a plurality of roller bogeys having rollers partially encircling a portion of the outer surface of the boom for guiding the boom through the tubular member.  In accordance with a third feature of the present invention, the tubular member is hingedly mounted on the boom support, so as to permit pivotal of the boom support about its horizontal axis to a position substantially parallel to the boom and so reduce the height of the boom above ground to a minimum to permit transportation of the motorized equipment on a trailer under bridges and other overhead obstacles.  In accordance with a fourth feature of the present invention, two pairs of jaws are pivotally mounted, one on the tubular member and the other on the front end of the boom, for gripping and delimbing felled trees.  The jaws of each pair are mounted in a longitudinally offset position and means are provided for interchanging the relative position of the jaws, so that both jaws can be easily seen by an operator seated at the operator control station, whether this control station is located on the right hand or on the left hand of the boom.

Abstract: TRUNCATED TRIANGULAR SKID PIPE                      Abstract A water-cooled skid pipe suitable for supporting metal shapes such as billets, blooms and slabs in a metal-lurgical reheat furnace.  The skid pipe has a base member, a pair of upwardly extending, converging side members and an apex member connecting the uppermost portions of the side members, all such members defining a passageway therethrough suitable for conducting a fluid.  A pair of shoulders extend outwardly of the junction of each side member and the apex member, which shoulders and apex member receive the slag which is deposited by the metal shapes onto the skid pipe and pre-vent the slag from migrating into the seam between the skid pipe and a surrounding insulator.  The shoulders further protect any suitable insulator, which can be applied around the base member and converging side members, from direct contact by the metal shape thereby substantially minimizing the impact of the metal shape upon the insulator.  The metal shape can be supported directly by the apex member or by a skid member secured atop the apex member.  The invention can be used outside a furnace as an improved structural support member.
