Abstract: An apparatus for reinforcing a structural member such as a beam or joist comprises a cable which is secured under tension to anchor brackets mounted on opposite ends of a beam. The cable extends across a face of the beam and across and in engagement with a bearing bracket mounted to the face of the beam intermediate its ends. The cable engages a cable engaging member on the bearing bracket and bears upward thereon. The cable thereby bears a portion of the load applied to the beam intermediate its ends, resisting distortion of the beam and providing increased recovery ability. First and second tension adjustment mechanisms are securable to the beam to engage the cable on opposite sides of the bearing bracket respectively to permit the tension on the cable to be adjusted. At least one end of the cable may be secured to an adjustable anchor bolt on the respective anchor bracket to further permit adjustment of the tension on the cable.

Abstract: A multi-bladed mulching mower comprises a cutting deck beneath which a plurality of cutting blades are carried. The cutting blades are shrouded so that each cutting blade is confined within a generally circular cutting chamber. Kicker members are located in each of the cutting chambers to help deflect cut grass particles downwardly into the uncut grass. Thus, a mower is provided suited for mowing relatively large areas which is also capable of dispensing the cut grass clippings into the cut grass path to serve as mulch.

Abstract: Method and apparatus for detecting insecurely glued closure flaps on wrap-around paperboard cartons and for diverting defectively sealed cartons from the packaging line. A striking device in the form of an impact roller strikes the leading edge of each carton as it moves along a conveyor belt. Loose or insecure flaps opened by the impact are detected as the carton passes through a photocell station. Upon identification of an open flap condition a pivotal eject chute forming a part of the conveyor table is actuated downwardly to divert the rejected carton to a remote location for inspection and resealing or replacement.

Abstract: A new and distinct hybrid elm selection, believed to be from a genetic background of Ulmus americana.times.U. pumila, which is characterized by extremely high vigor as compared to other elm trees of the same age. This tree is further characterized by having leaves which are larger, thicker, highly doubly serrate, and more symmetrical than those of comparison trees of comparison or parental species. The leaves of this tree have midrib and veins which are inserted below the top surface and protrude from the bottom surfaces of leaves, and are larger than those of other species.It seems the extra thickness of the upper surface of the leaves of this tree with the larger vein structure beneath causes the leaf surface to become curved in a retrorse curve, with the center portion of the blade being higher, and the outer portion curved slightly downward. The blade turned with the lower side up becomes dish shaped and will hold water in the center.
