Title: Truss panel

Abstract: ABSTRACT OF THE DISCLOSURE        A method and apparatus is disclosed for forming integrated truss structures wherein the molding apparatus includes a plurality of alternating male mold members and female mold members arranged in two opposed layers or mold havles.  The male mold members each have a plurality of open grooves formed therein which are disposed orthogonally therein and slope away from a top or plateau surface thereof.  Each of the female mold members has a centrally located, generally circular recessed cavity with a plurality of open grooves which are orthogonally disposed with regard to one another and which slop away from the plane of the recessed cavity.  When the two layers each including male and female members are positioned opposite one another, the open grooves in opposed male and female members become aligned to define strut beam chambers and plateau surface of the male member is aligned with the recessed cavity of the female member to define a junction chamber. Thus, a plurality of strut beam chambers slope away from each junction chamber.  When the mold halves are brought together they define between the alternate symmetrical upper and lower junction chambers interconnected by a plurality of strut chambers.  Channels are formed preferably in the female members, for injecting a moldable material such as plastic into the strut beam chambers and the junction chambers.  After injection occurs, the molds are separated to thereby form an integrally molded truss structure.  The resulting integrated truss structures can be incorporated with exterior or interiorly mounted members to make composite truss panel structures having a wide variety of uses.  The present invention also concerns techniques for securing such members to or within truss structures and the composite stuctures produced thereby.

Abstract: CARTRIDGE ASSEMBLY APPARATUS FOR TYPEWRITERS      Abstract of the Disclosure Disclosed is a ribbon tape-cartridge assembly, the cartridges being adapted for mating in superimposed over-lapping relation, bottom to bottom to form the assembly. Slots in tabs which project from the plane of one of the bottom surfaces of one of the cartridges coact with fins on the other of the cartridges, the fins movable into the slot for an interference fit with at least a portion of the tab.  Shoulders on each of the cartridges also coact for limiting relative movement of the cartridges in a first direction with respect to each other.  One of the cartridges is provided with a camming surface and a cam follower is provided the other of the cartridges, the cam and cam follower being engageable to effect relative move-ment between the cartridges in the first direction until the shouders abutt one another inhibiting further relative motion.  An additional slot in one of the cartridges is engageable with a projection on the other to further inhibit motion in a second direction perpendicular to the first direction, the cartridges being held together as by a latch so that when the cartridges are in superimposed overlapping relation, no relative movement may occur between the two cartridges.

Abstract: ABSTRACT OF THE DISCLOSURE            A razor is provided herein including an arcuate razor head which is shaped to conform to convex and concave body surfaces.  Cutting edges are emplaced in inclined arcuate surfaces, one above the other.  The inclined surfaces guide the cutting edges at an efficient cutting angle as the razor head is drawn over the surface of the body being shaved.  The inclined surfaces intersect in a line removed from the location of the cutting edges.  Both convex and concave arcuate cutting edges are immediately available to the user.  The user of the razor has immediate access to either of the cutting edges by simple rotation of the razor head handle in the user's hand.  No bothersome dismantling and reassembly of the razor head is required.

Abstract: A B S T R A C T       Methods and apparatus for drying a web of material running between a drying cylinder and a traveling covering cloth avoid the formation of air boundary layers which would impede heat exchange with respect to, and humidity removal from, the traveling web.  In particular, these methods and apparatus avoid excessive wear of the covering cloth by locating a baffleplate at a distance from the covering cloth within a domain of the boundary layer, and promote a heat exchange and humidity removal through turbulence by impacting air from the boundary layer against a front surface of the baffleplate at a distance from the covering cloth, causing an exchange of air in the boundary layer and in meshes of the covering cloth.  Effects of non-uniform humidity profiles are avoided by providing the front surface of the baffleplate with a varying configuration across the covering cloth.

Abstract: A B S T R A C T            A method of removing heavy metals, particularly cadmium, from wet-process phosphoric acid produced by digesting raw phosphoric mate-rial with sulphuric acid, by precipitating out the heavy metals in sulphide form. The residual sulphuric acid is removed first by neu-tralization with alkali or as a not-readily dissolved sulphate precipitate. Alkali is added to obtain an Me/P ratio within the range of about 0.05-0.3, where Me is the number of cation equivalents in the alkali and P is the number of phosphorous atoms in the phos-phoric acid , whereafter the heavy metals are precipitated out by adding a sulphide compound which is soluble in the phosphoric acid, and the sulphide precipitate removed.

Abstract: METHOD AND APPARATUS FOR KNITTING SLIVER            LOOP KNIT FABRIC                               Abstract A sliver loop knit fabric comprising a base fabric formed of knitted courses and wales and anchoring a plurality of tufts of sliver fibers, the free ends of which are incor-porated into at least two courses and two wales of the fabric to provide a generally loop pile fabric.  The fabric is knit on a circular jersey fabric knitter equipped with a plurality of fiber feeding cards.  The knitter also is equipped with pneumatic means for directing jets of compressed air generally radially outward of the needles of the knitting machine.  The jets of compressed air blow the free ends of the tufts of sliver fibers on the needles outwardly of the needle circle, and onto the tops of the sinkers, preparatory to incorporating the ends of the tufts into the fabric during knitting.  The bulk of the free ends are incorporated into the fabric in the form of knitted stitches.  Stray ends or "tailings" of the tufts arc pushed back between the needles inwardly of the needle circle by reciprocal sinkers, thereby those ends are interlaced about the needles preparatory to their interlace-ment in the form of floats into plural courses and wales of the fabric.

Abstract: ADJUSTABLE CONNECTOR FOR COUPLING TOWER    LEG TO FOUNDATION SUPPORT ANCHOR          Abstract of the Disclosure A connector assembly and method are dis-closed for supporting each of the legs of a free standing tower or the like using a screw anchor driven into the ground at the base of a respective tower leg.  In order to compensate for irregular-ities in alignment between the upper end of each screw anchor and a corresponding tower leg, the connector units are initially mounted on the screw anchors in a manner permitting individual axial, angular and longitudinal adjustment as may be necessary to bring each connector unit into proper alignment with a tower leg thereabove.  The connector units while being held in such aligned disposition may be precisely affixed to a corres-ponding screw anchor and the proximal tower leg using the connector unit itself as a guide for such interconnection.  Temporary adjustable support for the connector units takes the form of a unique removable holding fixture between a screw anchor and the connector unit thereon constructed and arranged to allow vernier adjustment of the connec-tor unit in axial and angular directions relative to the screw anchor to assure that each connector unit may be brought into precise alignment with a tower leg before the connector unit is rigidly coupled to the screw anchor below and the tower leg above. Requisite lateral adjustment is provided in the form of a slidable connection between the connec-tor unit and a base plate adapted to be joined to the tower leg supported thereby.
