Abstract: A water heater construction and method includes arranging the inner water tank and the surrounding outer shell in an inverted orientation and positioning the outer shell into a cover which is arranged with clearance openings for the plumbing connections extending from the top of the tank to extend therethrough. With the tank, shell and cover in an inverted and assembled condition, the annular clearance space defined between the tank and shell is filled, at least the majority, with liquid, foam-in-place insulation. By inverting the water heater and injecting liquid foam insulation material, the clearance space above the inner water tank is foamed first thereby assuring that the foam material at this location will have greater uniformity in foam density and cell structure than at the lower portion of the annular space so as to provide enhanced thermal efficiency at the most critical location.

Abstract: A coated porous metal panel includes a first outer surface on one side of the panel, a second outer surface on the other side of the panel, a plurality of laterally offset discharge and inlet pores in respective ones of the first and the second outer surfaces, an internal chamber in the panel communicating with each of the inlet and discharge pores so that tortuous gas flow paths are defined through the porous metal panel, and a shield lamina mechanically clamped against the second outer surface. The shield lamina has shield pores aligned with the inlet pores to permit gas flow into the inlet pores. A plurality of extraction passages are formed in the panel between the internal chamber and the second outer surface and directly behind each of the discharge pores. When the coating material is sprayed on the first outer surface with the shield lamina not attached to the panel, surplus coating entering the discharge pores passes through the extraction passages for collection behind the panel.

Abstract: An insulated panel for a domestic or household appliance is formed by a process in which two sheets of plastic material are extruded from a co-extrusion die and moved directly into a die thermoforming fixture. When the open die members are closed, the edges of the two sheets are sealed together to form a hollow panel and the walls of the panel are forced outwardly to conform to the shape of the die members. After the hollow panel is trimmed it is moved to a foam machine preferably while still contained in the thermoforming fixture so that foam insulation is inserted into the hollow panel while the walls of the panel are supported by the die members so that these walls are not deformed while the foam insulation is added.

Abstract: An annular resilient compressible flexible-urethane dam (10) is placed around the inner storage tank (14) of a water heater. The dam has a free-state inner diameter (24) slightly less than the outer diameter of the tank, and a free-state outer diameter (26) slightly greater than the inner diameter of the outer jacket (18).

Abstract: A narrow elongated housing is provided constructed of an inner ribbed conduit which is overlaid with two layers of high strength rods. Each layer is contra-helically wrapped with opposing end portions compression secured in a termination chamber. The chamber is formed between a sleeve, which is attached to opposing ends of the conduit, and an outer termination enclosure.

Abstract: A vehicle body pillar has a cavity therein through which air flow creating undesirable noise and in which moisture and fluids such as water are not to be collected. An expandable sealant plug is inserted therein and retained in place. The sealant material forming the plug is later expandable under controlled conditions. It is preferably expandable under temperatures of about 275.degree. F. to 400.degree. F. over a period of time. Preferably during the electro-coated paint baking and curing operation, the sealant is exposed to appropriate temperatures for sufficient time to expand the sealant about 800% and cure it, sealing the cavity so as to prevent the flow of air through it. The expanded sealant also effectively blocks the intrusion of fluids such as water, minimizing corrosion within the pillar.

Abstract: A method of manufacturing a composite camshaft having a shaft positioned within appropriately aligned and fixtured annular cam and bearing elements, each having interior protrusions that increase in size toward the tube axis. The shaft and elements are supported in a mold and a flowable, hardenable material is injected to fill the space between the tube and the elements for securing the elements to the shaft. The protrusions enhance the grip of the plastic with shrinkage. The shaft and the cam elements have nesting configurations that form a continuous space therebetween such that the hardened material compressionally resists torsional forces between the shaft and cam elements. Injection molding is performed without substantially stressing the freely supported shaft and without applying undue strain to the elements by providing undercut portions in the mold surrounding part of the exterior surface of the elements with high pressure plastic during injection.

Abstract: A method for progressively making a model of a sheet metal assembly composed of several connected sheet metal panels, or a model of several interfitting sheet metal assemblies. Each sheet metal panel is represented by a carbon fiber sheet formed between a pair of blocks machined to form a cavity corresponding to the thickness of the sheet metal. The thickness is initially represented by a wax layer corresponding to the thickness of the sheet metal. The wax layer is removed and replaced by a carbon fiber epoxy-based material. One of the blocks is then used to form the replica of a second panel of the sheet metal, adjacent the first panel. The process is repeated until replicas of all panels have been made. The carbon fiber replicas are attached to one another to form the completed model of the sheet metal assembly or a model of several interfitting sheet metal assemblies. The machined foam blocks may be used as tooling aids for forming dies for stamping the sheet metal components.

Abstract: A method of producing a discarding propelling cage sabot projectile, and to a discarding propelling cage sabot projectile produced according to this method, in which, in a vulcanizing tool including an injection mold, a uniformly thin layer of rubber is applied to the rear gas pressure receiving surface of the sabot so as to secure and seal the individual sabot segments against one another. In such a method, when the liquid sealing material is injected into the injection mold, there exists the danger that, due to the high pressure existing at that time, sealing material may enter, in an uncontrolling manner, into the cylindrical inner annular gap or annulus between the sabot and the projectile body. This may considerably adversely influence the release behavior of the discarding sabot segments and lead to a reduction of hit accuracy.
