Abstract: ABSTRACT OF THE DISCLOSURE        Homogeneous, storage-stable, dry-blendable, hydrocar-bon solution non-polar rubber powders having a DSV from about 1.5 to about 7.0 (100 parts) containing carbon black, are pre-pared by sequentially grinding carbon black (60-90 phr) in water; mixing at a temperature of 20° - 100°C the resulting composition with a hydrocarbon solution of non-polar rubber, about 5 - 25%      (w/W), to form a liquid two phase dispersion of (a) hydrocarbon, solvent, carbon black, and rubber, and (b) water; stripping the liquid dispersion of solvant by adding, at a rate of between about 360 - 1270 g./min. the dispersion to vigorously stirred hot water (85 - 120°C) in the presence of at least one foam inhibiting surfactant selected from the group consisting of (a) low-foaming nonionic polyether alcohols with blocked terminal hydroxyl group (0.01 - 5.0 phr), and, (b) cationic tetraalkylammonium salts having more than 25 carbon atoms in the cation thereof (0.01 -5.0 phr), to produce powder; and drying the powder to produce a homogeneous, clean and free-flowing powder having a mean par-ticle size from 0.8 to 1.5 mm., with about one-half of the par-ticles having a particle size greater than 1.0 mm. Totally compounded rubber powders can also be produced by dry-blending, powder compounding, for about 2.5 to about 3.5 min. at 1000 -5000 r.p.m., the solution rubber powder obtained with from about 45 to about 60 phr oil, and, from about 0.1 to about 20 phr, collectively, of at least one pigment, at least one preservative and at least one curative. Utility for the totally compounded solution rubber powder blend is found in the production of, for exemple, injection molded articles, extruded exterior coatings in electric cable construction, tire construction, and, the pre-paration of gaskets for hose and pipe which can be utilized in both automotive and home construction.

Abstract: RESTRICTED-GROWTH ADHESIVE-APPLIED WOOD FLOORING SYSTEM AND METHOD OF MAKING THE SAME                 ABSTRACT OF THE DISCLOSURE            A restricted-growth resiliently cushioned adhesive-applied antibuckling wood flooring system is provided.  The wood-en floor members are held in place by a predetermined thickness of elastomeric cushioning adhesive material substantially filling the space between the wood flooring members and the supporting base.  The elastomeric cushioning adhesive material has sufficient gripping and tensile strength to overcome very substantial hori-zontal and vertical expansive buckling forces which can be gener-ated by an increased moisture content within the wood flooring members during periods of adverse moisture conditions.  The elas-tomeric cushioning adhesive material also provides uniformly re-silient cushioned support under the wood flooring members.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for treating under pressure aqueous liquids with ozone are disclosed employing a plurality of eductor-fed liquid treatment tanks in series for treatment of a stream of liquid.          An upstream eductor-fed tank entrains and treats a stream of raw liquid with a residual ozone-containing gas stream, cycled upstream from a downstream treatment tank, and thereafter a downstream eductor-fed tank entrains and treats the discharge with a fresh ozone-containing gas stream.  A continuous closed liquid treatment system and recycle of ozone carrier gas are provided.  This invention thus provides full utilization of ozone-containing gas streams and balances that utilization with the requirements of decontamination or ozonization of aqueous streams in a continuous system.

Abstract: MULTI-STEP HEAT TREATMENT FOR SUPERALLOYS     ABSTRACT OF THE DISCLOSURE    This invention relates to a multi-step heat treatment method for increasing the elevated temperature mechanical properties of nickel base superalloys.  The heat treatment method is particularly applicable to those conventional alloys which have a cast structure consisting essentially of a gamma matrix containing a gamma prime second phase precipitate and regions of low melting constituents.  The effect of the process of the invention is to maximize the volume fraction of the fine gamma prime precipitate, by a solution treatment and reprecipitation, without causing significant incipient melting.

Abstract: ABSTRACT OF THE DISCLOSURE     An expansion plug formed in one-piece from plastic material is disclosed.  The plug has a wedging sleeve forming the inner end and a collar forming the outer end with a central portion formed therebetween.  An axial cavity extends through the collar and the central portion and an axial opening is provided in the wedging sleeve to receive a threaded fastening member.          Diametrically opposed deformable webs extend longitudinally in the central portion and joins the wedging sleeve and the collar and are adapted to buckle outwardly upon movement of the wedging sleeve towards the collar as a result of rotation of the threaded fastening member.  The deformable webs are defined by longitudinal slots in the central portion and these slots also form anchoring legs which extend the length of the central portion.  Ends of the anchoring legs adjacent the wedging sleeve are provided with obliquely inclined surfaces adapted to be contacted by obliquely inclined surfaces on the wedging sleeve to spread the anchoring legs as a result of the said movement of the wedging sleeve.

Abstract: Abstract of the Disclosure A trap incorporating an access fitting and of the type that may be designed into a P-trap, or S-trap configuration, the trap including an inlet segment and an outlet segment, both being integrally joined together, and a lower arcuate portion forming the access fitting that intervenes and joins together for communication the interior channel through the trap, the interior channel being of a fixed diameter throughout its extent, and forming a continuous smooth wall interior surface along the entire length of the trap.  A flange projects integrally from both the combined upper inlet and outlet integral sections, while a corresponding and registering flange extends from the arcuate portion for arrangement in alignment with the upper segment flange to facilitate assembly of the trap.  The plane of separation between the upper segments and the lower arcuate portion or fitting is provided between the weir formed by the interior surface of the channel formed between the upper inlet and outlet segments, and that location downwardly therefrom where the fixed diameter of the channel commences to reduce in dimension below its full diameter due to its lower disposition within the arcuating portion of the access fitting of the trap.

Abstract: ABSTRACT OF THE DISCLOSURE:          This invention is concerned with a process for protecting a PVC surface against the effects of sunlight, comprising the step of applying to the PVC surface to be protected, a surface layer of polymethyl methacrylate, or a copolymer thereof.  The surface layer is so applied that it firmly adheres on the PVC surface, and it contains color pigments and UV stabilizers and/or UV absorbers so that it be almost impermeable to UV radiations. This process is characterized in that the surfac? layer is made to be not absorbent of any IR radiation, the IR radiation being reflected by an appropriate pigmenting of the PVC layer with IR-reflecting coloring agent upon the impingement thereof.
