Abstract: ABSTRACT OF THE DISCLOSURE         A method for quickly manufacturing a connector plate of varying design strength in a minimum size plate for joining wooden members which approximates the ideal connector plate for that particular design, thereby making it unnecessary to use plates of greater strength than required.          The plate is produced with a controlled number of teeth extending transversely outwardly from one major side of the plate in varying patterns.  The new and improved method includes feeding sheet metal stock of predetermined width through a die having a plurality of punches that are controlled for relative movement with respect to the stock, striking the sheet metal plate with the die at predetermined intervals to form the particular desired pattern of teeth extending from the plate and leaving a plurality of longitudinally extending slots formed in the plate, and cutting the plate when the desired total length of the plate is reached.          Therefore a variety of connector plates may be constructed of minimum area, while realizing maximum tensile strength.          A method of making an ideal plate can be accomplished by feeding stock into a punch press having a die with a plurality of punches configured in an ideal pattern, and punching the stock making an ideal connector plate.

Abstract: ABSTRACT An apparatus and method are disclosed for forming a loop of flexible binding about objects positioned seriatim in an object receiving station. The apparatus includes a chain loop driven around the object receiving station.  While a previously bound first object is in the receiving station, the chain is driven in one direction to move carrier rollers on the chain so as to pull the trailing portion of a binding through a major portion of the locus of a closed path around the receiving station while the lead end of the binding is held adjacent the receiving station.  Spaced portions of the binding are guided from the interior of the path around the receiving station to maintain the binding in the configuration spaced outwardly of the receiving station.  Subsequently, the first bound object is removed from the receiving station and a second object is positioned therein.  The guiding of the interior of the binding around the receiving station is terminated so as to permit the binding to contact the second object while further pulling the trailing portion of the binding to complete the closed path and then form a tensioned loop about the second object.

Abstract: Abstract of the Disclosure A device for storing and dispensing a suture includes an outer envelope formed of two panel layers which are sealed along their peripheries so as to hermeti-cally enclose a region therebetween.  An inner container positioned within the region includes rectangular upper, center and lower panels which are foldably secured along respective score lines.  The upper panel has a pocket formed by an overlaying window to snugly retain a needle therein.  The upper panel is folded back onto the center panel which receives and retains a major portion of the suture secured to the needle.  The lower panel is also folded over the center panel and is coupled to the upper panel.  Both the upper and lower panels are capable of slidably moving over the center panel.  Interlocking panels secured to lower panel sides lock the upper and lower panels together.  Score lines across the upper and lower panels permit the upper and lower panels to inter-act so that flexing of one panel from a raised configura-tion to a generally flat configuration causes the other panel to flex from a generally flat configuration to a raised configuration.  A window is provided in the upper panel layer and overlies the window of the center panel so that the needle and a portion of the thread are viewable therethrough.  After tearing or removing a portion of the upper panel layer so as to expose the window on the center panel, the upper panel layer is depressed adjacent the score line across the lower panel so as to expose a portion of the needle together with a portion of the suture free of the surface of the upper panel.  A method for storing and dispensing the suture and respective needle is also disclosed.

Abstract: METHOD OF MAKING FILTER CELL    HAVING SEALED PERIPHERY     ABSTRACT     A method is provided for making a filter cell comprised of two cellulosic fiber containing filter media having a sealed periphery.  The method comprises compress-ing the peripheries of each filter media, to form a flange.          The media are then aligned to provide intimate face-to-face contact between the flanges.  A spacer means is provided between the media to cause each to dish outwardly from the other media.  The two media and spacer means are then placed into a mold surrounding -the flanges.  The mold has a means for providing a recompression force to the inner portions of the flanges.  A thermoplastic polymer is then injected into the mold to form a seal around the flanges.  The recompression force is sufficient to maintain the flanges in intimate face-to-face contact with each other and to prevent seepage of the polymer between the flanges when the polymer is injected into the mold.  The sealed periphery is reliable, economical to produce, resistant to cracking, provides enhanced support for the filter media, and permits the production of a filter cell having low extractables.
