Abstract: A heat exchanger is formed of inner and outer fluid tubes. The inner fluid tube has a profile that undulates in a smooth manner toward and away from the centroid of the inner fluid tube as the profile extends circumferentially about the centroid. The inner tube has axially opposite end margins that each form cylindrical tube portions. The cylindrical tube portions have a diameter greater than the diameter of the remainder of the inner fluid tube. The inner fluid tube defines an inner fluid passageway. The outer fluid tube encircles the inner fluid tube and extends from one of the cylindrical tube portions of the inner fluid tube to the other in a manner defining an outer fluid passageway between the inner fluid tube and the outer fluid tube. The outer fluid tube has an inlet and an outlet that extend radially through the outer fluid tube.

Abstract: A non-skid coating described herein attempts to overcome the deficiencies of the conventional coatings with improved external durability and color retention, a reduced level of VOCs, and direct-to-metal (DTM) adhesion using organo-siloxane chemistry. The non-skid coating has a first component having an amino-functional siloxane resin; a second component having a non-aromatic epoxy resin; a spherical filler for lowering viscosity; a pigment; a coarse aggregate; and a thixotropic agent. The amino-functional siloxane resin can be an amino-functional methyl phenyl polysiloxane, diphenyl polysiloxane or silsesquioxane-based resin. The non-aromatic epoxy resin can be cycloaliphatic or aliphatic. The first component is about 5% to 20% weight of the coating, and the second component is about 80% to 95% weight of the coating.

Abstract: A food product having the crisp texture, golden brown appearance and fresh fried taste of conventionally-fried foods, comprising a food substrate coated with a cereal-based batter containing sodium caseinate and no egg albumen in which the batter has a solids level of at least 30 percent by weight and provides at least about 0.2 percent by weight of sodium caseinate.

Abstract: A concrete column forming tube and method of making same for receiving poured concrete column therein to produce a concrete column is characterized by a smooth inside coated surface in the forming tube to eliminate spiral seam lines and other undesirable characteristics on the outside surface of the formed concrete column. The tube is formed from spirally-wound plies of paper adhered together and has a centrifugally-cast epoxy resin coating sprayed onto the inside surface of the spirally-wound tube while the tube is rotating to produce a smooth inside coated surface on the forming tube.

Abstract: A single-ply wound paperboard tube is disclosed as is its forming method. The method comprises applying an adhesive to a paperboard ply having relatively thin longitudinal edges and a relatively thick central portion therebetween, then spirally winding the ply about a mandrel in edge-overlapping relation. Preferably, the thinned edges and the thick central portion of the ply share a common face, and the ply is preferably steam-conditioned to raise its temperature and its moisture content prior to the application of the adhesive.

Abstract: A method for preparing rings having an integral stiffening geometric pattern on its outer surface is disclosed. The method employs a variation of the drum rolling process, but it incorporates unique tooling for providing the pattern, preferably comprising a plurality of segments which fit together to define a ring, the inner surface of which presents the desired pattern toward the center of the ring. A unique drum arrangement includes inner and outer components for locking the segments in place and for providing the structural integrity required for the final drum rolling operation. A cylinder, for example an aluminum or aluminum alloy cylinder, is placed in the drum, the cylinder being preformed and presized to fit concentrically within the segment defining ring. Following heating of the assembly to forming temperature, the cylinder is radially expanded using a sizing tool, and the assembly is then placed over a mandrel in preparation for drum rolling.

Abstract: Detecting and locating leaks in building service lateral sewer pipelines is accomplished under remote control by inserting a lateral inspection television camera into the lateral pipeline from a main sewer pipeline. The lateral inspection camera is stored in a generally cylindrical launcher mechanism having a camera port opening through which the lateral camera may be projected and retracted using a hollow elongated and flexible push rod. The launcher is moved longitudinally in the main pipeline, along with a main television camera, until an entrance opening to a service lateral pipeline is viewed via the main camera. The launcher mechanism may also be rotated in order to properly align the camera aperture with the entrance to the lateral pipeline. The lateral camera can be propelled into the lateral pipeline by means of motor driven pinch rollers in the launcher mechanism pushing the push rod.

Abstract: A connector for connecting a pair of electrical leads to a ground electrode includes an upper connector plate and a lower connector plate, both formed of an electrically non-conductive material, and a pair of leaf spring contact means which are connected to said upper and lower connector plates and by which the plates are spring biased apart. A pair of connector posts are mounted on the side of the lower plate facing the upper plate, and may be engaged by a spring biased latch means carried on the upper plate. The latch means holds the lower and upper plates together securely with the connection tab of an electrode therebetween.

Abstract: A limestone flue gas scrubbing system includes a confining means which collects the effluent from the spray tower. A portion of this effluent is removed to a secondary reaction tank which operates at low pH for increased utilization of the additive. A first portion of the flow from the tank is passed to waste with the liquid portion returning to the main additive tank. A remaining portion of the slurry from the secondary tank is recirculated to the spray tower in parallel with the main slurry flow from the main reaction tank.

Abstract: A multi-speed transmission with piston assemblies made from sheet metal stampings for selective engagement with multi-disc friction devices. Each piston assembly comprises a thin wall shell stamped from sheet stock. The shells have outer and inner support shoulders adjacent to outer and inner rims onto which are pressed annular retainers that form grooves for elastomeric lip seals. In one embodiment the contact member for the piston assembly comprises a sheet metal member curved until the ends almost meet. The contact member is retained in a shell by its expansion force acting against an annular retainer wall. In a second embodiment the contact member is formed by extending the outer rim axially.
