The tubes are disposed on the inter-nal plates such that at at least one location thereon a straight line extending entirely across said internal plates will inter-sect only the one intermediate tube.  The external shells are stamp formed to define a plurality of chambers which cooperate with the tubes in the internal plates.  The chambers are sepa-rated from one another by a crease disposed to align with the intermediate  tube.   The  crease  is  characterized by a  single outwardly  convex  portion  to  engage  the  single  tube.   As  a result, the crease is not provided with recesses that conceiva-bly could retain corrosive materials.

Granted: 1995-08-29
Abstract: An internally pressurizable lightweight high tensile strength multi-layered structure with an outer barrier layer envelope of elastomeric semi-permeable material for use as a cushioning device is provided.  The outer barrier layer is bonded, at a multiplicity of sites, to substantially the entire distal surfaces of a double-walled drop-thread linked fabric wherein the filaments are comprised of a highly distorted, long chain, axially orientated crystalline molecular structure which has a low gas permeability.  The bond between the barrier layer and the facing fabric is substantially increased by the presence of fibrils and texturizing.  The drop threads which are likewise texturized, function as stress averaging members to maintain the composite structure in either a substantially flat or planar or contoured configuration without weldments within the select load-bearing areas.  This lightweight product is capable of withstanding very substantial internal inflation pressures, under severe long-term steady state and cyclical compression and flexural fatigue conditions.  The product is inflated, pressurized and sealed and maintains the internal inflatant pressure for extended periods of time, generally in excess of the useful life of the overall product, by employing the diffusion pumping phenomenon of self-inflation.

Abstract: An emulsion acrylate copolymer is provided which unexpectedly is an effective magnetic binder inasmuch as it can be loaded with high amounts of one or more magnetic particles such as ferrite or ferrite containing materials to provide a flexible permanent type magnetic composition of high magnetic energy.  The copolymer is made from an alkyl acrylate and a salt of 2-acrylamido-2-methylpropane sulfonic acid (AMPS~).  A carboxylated ethoxy alkyl phenol surfactant is utilized which provides good processability and permits a blend of the magnetic particles with the emulsion acrylate copolymer to be precipitated from a latex  solution by high  shear mixing.    Flexible high magnetic energy magnets can thus be made and utilized in various applications such as refrigerator doors, electrical motors, and the like.

Abstract: ABSTRACT           A package assembly for transporting hazardous materials including a bottle containing a hazardous material disposed within a metal can wherein the bottle is surrounded on all sides by individual upper, lower and side absorbent non-resilient and frangible synthetic resin foam elements.  The foam elements provide cushioning for the bottle and absorbency in case of spillage.  The individual foam elements are maintained out of contact with each other by means of fiberboard spacers.  The spacers are disposed to separate the upper and lower ends of the bottle from the resin foam and to protect the frangible foam from disintegration due to abrasion by the bottle.  The metal can can be suspended within an outer corrugated fiberboard box by means of a fiberboard insert element for the outer box.  The fiberboard insert element supports the can out of contact with the outer fiberboard box and provides a protecting buffer zone between the can and the walls of the outer fiberboard box for the protection of the can.

Abstract: ABSTRACT                        REGENERATION OF FLUID CATALYTIC CRACKING CATALYSTS     An FCC catalyst regeneration technique in which the catalyst is regenerated in a dense bed regenerator.  Regeneration effluent gases are collected from different parts of the regenerator vessel in a common collection zone and passed through the catalyst separation cyclones from the common collection zone.  The cyclones may be arranged with their inlet horns adjacent one another in the common collection zone or a cyclone inlet manifold with a common inlet may be connected to the cyclone inlets.  The inlet port to the manifold may be extended to form an elongated vertical duct through which regeneration effluent gases and entrained catalyst pass from the dilute phase of the dense bed to the cyclone so that mixing of the effluent gases is promoted to ensure combustion in residual quantities of oxygen present in the effluent gases before the gases enter the cyclones.  Improved operating flexibility is obtained together with a reduced likelihood of cyclone damage as a result of localized high temperature excursions.  In addition, the NOx level of the regenerator stack gases is reduced by introducing unregenerated spent catalyst at different heights of the regenerator and contacting such catalyst with regeneration effluent gases.
