Abstract: BARK EXTENDED PHENOLIC RESIN ADHESIVE COMPOSITION           AND PROCESS FOR PREPARING SAME                       Abstract of the Disclosure A new and improved, high quality, bark-extended phenolic resin adhesive composition for bonding wood plies, particularly southern mill wood such as the southern pine, comprising the reaction product of finely ground wood bark particles treated with a caustic solution and a low molecular weight, aqueous alkaline phenol-aldehyde resin.  The resin has a low degree of polymeriza-tion and is soluble in all proportions in ethanol.  The resulting adhesive has a proportion by weight of total resin solids in the range of approximately 25.1% to 20.9% and a proportion of total solids in a range of approximately 40% to 40.85% based upon the total weight of the adhesive composition.  The adhesive has a viscosity in a range of approximately 9,000 centipoise to 10,600 centipoise.  An adhesive of this type particularly suitable for bonding western wood species such as the Douglas fir comprises the reaction product of finely ground wood bark particles treated with a caustic solution, a low molecular weight aqueous alkaline phenol-aldehyde resin having a low degree of polymerization, which resin is soluble in all proportions in ehtanol, and various fillers such as wheat flour, Norprofil (Norprofil is a trade name for powdered or ground corn and rice husks or corn cobs), etc. The proportion of total resin solids is in the range of approximately 24.6% to 21.9%, and the proportion of total solids is in the range of approximately 40.28% and 38.6%.  The viscosity of the resulting adhesive is in the range of approximately 2,100 centipoise to 1,975 centipoise.  The processes for preparing the subject adhesives include preparing a premix comprising bark, a caustic solution, and water, then adding and mixing the remaining components under varying time conditions.  There is no requirement for the external addition of heat.

Abstract: ABSTRACT OF THE DISCLOSURE         Apparatus is disclosed for igniting gas emitted through a tip of a gas burning torch.  The apparatus includes means having an electrode which discharges a spark for igniting the gas emitted through the tip.  A frame is used to support the gas igniting means on the torch and permits movement of the electrode from a stored position to an igniting position, so that upon discharge of the spark, the gas emitted from the tip is ignited.  The apparatus being adapted to initiate the spark directly at the tip and in the flow of gas directly as it leaves the tip, thus to provide instant ignition of the gas.          A hanger is adapted to fit a portion of the torch to attach the frame to the torch so that the frame is usable with different torches by using a different hanger.

Abstract: Form CHILD-RESISTANT SAFETY CLOSURE               ABSTRACT OF THE DISCLOSURE         A child-resistant, safety closure for a container having a dispensing end including a threaded neck portion onto which the closure is adapted to be threadably assembled.  The closure features a double sidewall construction comprising an interiorly threaded, annular, inner sidewall threadably attachable on the container neck portion and an annular outer sidewall surrounding the inner sidewall in radially interspaced relationship.  The outer sidewall is provided with a flexible and resiliently distensible distal end portion extending axially beyond the inner sidewall and provided with at least one interlocking member on its interior surface and secluded from view within the interior confines of the outer sidewall, which is adapted to interlockingly engage at least one comple-mentary interlocking member on the dispensing end of the container when the closure is in either a fully closed position on the container neck portion or in at least one additional partially removed position on the container neck portion.  The interlocking members function in such manner that interlocking engagement occurs automatically when the closure is threadably advanced to its fully closed position on the container neck.  Retro-gressive rotation for threaded removal of the closure, however, requires manual compression of the flexible distal end of the outer sidewall, applied at locations straddling the interlocking members, coupled with concurrent retrogressive movement of the closure.  Ordinarily, such manual manipulation must be repeated at each interlocking position of the closure, and, therefore, removal of the closure requires both manual dexterity and knowledgeable intent beyond the capability of young children or other persons of comparable capabilities.  Moreover, as a further safety factor, the interlocking members are constructed and arranged in such manner that they are inaccessibly and unobservably secluded within the interior confines of the closure when it is interlocked on the container.         Alternative embodiments of the invention feature the provision of means for providing a frictional, fluid-tight seal, such as plug seal or bead seal, between the safety closure and the neck portion of the container which serve to prevent leakage of the container's contents even though the closure is partially removed from its fully closed position, or which is operative to prevent leakage of the container's contents at and between both the fully closed and the succeeding partially removed interlocking locations of the closure on the container end.

Abstract: ABSTRACT OF THE DISCLOSURE:       A coupling device particularly advantageous for use in connecting parts of unlike material comprising a flexible strip formed element having a resilient core.  In preferred embodiment this core is covered or substantially sheathed in an envelope which is preferably of non-porous flexible material capable of heat transfer, the outer surface of which mounts a pressure or heat sensitive adhesive.     The strip body is characterized in one form by the feature that on application of a predetermined range of heat it will self adapt in form and/or contained volume to the load of contacting parts, in the process of which the adhesive will bond to such parts and the body of the strip will form a seal between the parts in contact, irrespective of irregularities in the contacted surfaces.     An aspect of the invention of considerable importance is the concept of controlled flow so that coupling devices, on deformation thereof under load, will inherently seek the proper direction of flow, self dispersing in a manner to minimize and avoid surface contamination and effect optimal positioning of adhesive parts.

Abstract: TITLE: A METHOD AND APPARATUS FOR FORMING A COMPOSITE   MAT OF DIRECTIONALLY ORIENTED LIGNOCELLULOSIC FIBROUS MATERIAL     Abstract of the Disclosure The description describes a process and apparatus for forming a composite mat of directionally oriented lignocellulosic material in which elongated small pieces of the material are caused to descend indi-vidually as separate and discrete objects through an electric field orienting zone.  A horizontal mat-support surface is moved immediately below the orienting zone to receive the descending pieces thereon with the elongated pieces overlapping each other to form a composite mat.  An electric current is passed through the mat to produce a directional electric field immediately above the mat in which the electric field is directed in the direction of movement of the mat and parallel with the mat to exert forces on the elongated small pieces to cause the pieces to orient their long dimensions in the direction of the electric field as the pieces descend through the orienting zone in the formation of the composite mat.  The electric current is produced within the mat by con-tacting the mat with electrodes and applying a voltage difference between the electrodes to cause electric current to flow through the mat between the electrodes in the direction of mat travel.

Abstract: ANCHOR BOLT ASSEMBLY               Inventor:  Louis N. Giannuzzi, a citizen of the United States of America and resident of Cos Cob, Connecticut.     ABSTRACT OF THE DISCLOSURE          A vibration-proof anchor bolt assembly which is insert-able in a hole drilled in masonry for fastening a fixture to the surface thereof, the diameter of the hole being slightly larger than that of the bolt.  The bolt is provided with an enlarged head that lies against the fixture and is engage-able by a torque tool, the threaded rear section of the bolt being of reduced diameter.  The upper portion of the rear section is encircled by an expansible shell which when expanded is forced against the wall of the hole to anchor the bolt therein.  Received on the lower portion of the rear section is a wedge nut having an upper conical zone and a lower ring zone whose normal diameter is larger than that of the hole, slots being cut into said ring zone to define spring fingers.  These fingers are inwardly flexed by the wall of the hole when the assembly is inserted therein, thereby compressing the ring and constricting the internally-threaded bore thereof.  When the bolt assembly is fully inserted in the hole and the bolt head is turned by the tool, the wedge nut, whose rotation is arrested by the compressed ring, is axially advanced toward the shell, the conical zone of the nut entering the space between the shell and the rear section and acting progressively to expand the shell against the wall of the hole until a point is reached where the threaded end of the rear section enters the constricted bore of the compressed sing.  The resultant advance of the wedge nut wedges the threaded portion of the bolt between the compressed spring fingers, forcing these fingers outwardly against the hole of the wall, to create pressure between the mating threads which prevents loosening of the bolt under vibratory conditions.

Abstract: ABSTRACT OF THE DISCLOSURE        A feed water preheater has an integral desuperheater and an integral subcooler   through which passes the feed water tube bundle.  To prevent the penetration of steam into the supercooler at the point where the feed water tube bundle passes from the  subcooler  into the condensation space through a support plate, the tubes of the tube bundle are surrounded by sleeves which are fixed to the support plate.          Steam flowing through the sleeves condenses and fills the sleeves to prevent the entry of steam into the subcooler.          Sleeves are also provided at points where the tubes pass between the desuperheater and condensation space to reduce the velocity of steam traveling from the former to the latter.          The latter sleeves can be oriented vertically in the case of a vertical preheater, as long as they are longer than the thickness of condensate disposed on the support plate in the condensation space.
