Abstract: A heterogenous hybrid thermally regenerable salt sorbent resin is formed from a hybrid precursor resin. The hybrid precursor resin is formed by intimately mixing a dry, solid crosslinked macroporous copolymer with a solution containing a polyunsaturated monomer, a monoethylenically unsaturated monomer containing a haloalkyl group and a polymerization initiator, followed by heating to cause polymerization. The hybrid precursor resin is then treated with a weak base, then subjected to hydrolysis conditions to form, respectively, weak base groups and weak acid groups to produce the hybrid thermally regenerable salt sorbent resin.

Abstract: An improved system of resins comprising a combination of a sulfate-specific strongly basic anion exchange resin and a heterogenous hybrid thermally regenerable salt sorbent (TRSS) resin is provided. The anion exchange resin contains triethylamine and/or tributylamine groups. The TRSS resin comprises a macroporous host copolymer and a crosslinked guest copolymer having, respectively, weak acid groups and weak base groups. The system is used to treat feed water containing dissolved ions, including sulfate ions, and is efficiently regenerated.

Abstract: An electric arc furnace comprises a bottom, a roof and a side wall. The side wall is formed from a plurality of bimetal panels each having an inner copper face and an outer steel face. The roof may be formed with similar bi-metal panels. The hollow panels include internal baffles to define channels through which cooling water flows. The copper face is smooth and free of welds so as to maximize thermal heat transfer by the panels. The copper face enhances thermal efficiency and minimizes maintenance requirements of the panels, while the steel face reduces manufacturing costs of the panels.

Abstract: An end cap is provided for adjacent pipes in the cooling coils of an electric air furnace. Each end cap includes parallel opposite side walls and a curved end portion connecting the side walls. The side walls and end portion define a perimeter edge, the outer portion of which is beveled. The end cap includes a pair of tabs extending from each side wall. The tabs partially fill the crevice between adjacent end pipes so as to provide a stronger weld between the end cap and the pipes. Internal turning vanes in the end cap minimize turbulence of the liquid coolant flowing through the pipes. Similar turning vanes can be provided in the 90.degree. elbows of the cooling coils.

Abstract: An apparatus for connecting a polymeric composite pickup truck cargo box to a metallic vehicle frame without damaging the polymeric composite material of the pickup truck cargo box. The connecting apparatus is a tapping plate which allows for the distribution of forces applied by a self-tapping fastener over a broad area of the pickup truck cargo box so as not to tear or puncture the polymeric composite material. The connecting apparatus also separates the polymeric composite pickup truck cargo box from the metallic vehicle frame so that the polymeric composite material does not degrade over time.

Abstract: A connecting apparatus for connecting a composite outer body panel of a vehicle to a composite underbody of a vehicle whereby the composite outer body panel is allowed to move relative to the composite underbody due to thermal expansion and contraction caused by the aforementioned members having different coefficients of linear thermal expansion. The connecting apparatus is subtle in appearance, hidden from outside the vehicle and simple to assemble and disassemble.

Abstract: A cargo box for a truck having side panels formed with wing section which extend forwardly in close proximity to the side portions of the cab to conceal the gap between the front of the cargo box and the rear of the cab. Each of the side panels are formed of a relatively flexible material so as to allow the wing sections to contact the cab without causing any damage when the truck frame is subjected to twisting while traversing rough terrain.

Abstract: A C-shaped panel is mounted on the engine compartment side of the engine bulkhead structure and has upper and lower walls projecting forwardly form the bulkhead structure to overhang the engine. A vertically extending front wall is spaced forwardly of the bulkhead by the upper and lower walls to define therewith a transverse air flow communicating passage. Air inlet openings are provided in the top wall to admit air into the passage. The C-shaped panel overlies an opening through the bulkhead to communicate inlet air to the heating, ventilating and air conditioning system. A plurality of removable fasteners removably fasten the panel on the bulkhead to permit removal of the C-shaped panel from overhanging the engine to thereby facilitate and enable engine repair and removal. The windshield wiper motor is mounted on the C-shaped panel within the air flow passage so that removal of the C-shaped panel upon release of the removable fasteners also removes the windshield wiper system for repair and replacement.

Abstract: The disclosure is directed to a seal forming means in a valve plug for use in a fluid control valve, particularly in high temperature and high pressure fluid applications. The valve plug of the invention generally comprises a main valve plug member and a seal forming member associated therewith. The seal forming member is axially aligned with the main valve plug member and includes an outer wall having a surface that is coincident with an imaginary surface extension of the outer surface of the main valve plug. The seal forming member comprises a durable material having predetermined resilient characteristics, whereby said seal forming member is resiliently compressible within a predetermined range of compression. Moreover, the seal forming member includes an interior space and a finite section of minimum wall thickness formed in the outer wall. A packing material is tightly received and compressed within said interior space and, means are provided for compressing the seal forming member upon valve shut off.

Abstract: The disclosure is related to a high temperature, zero leakage packing assembly for use in connection with the valve stem of a high pressure control valve. The packing assembly is particularly suitable for use in the control of high temperature, high pressure fluids containing corrosive materials, such as molten salt. The packing assembly generally comprises a bushing arrangement forming the lowermost portion of the assembly and a plurality of series arranged, axially stacked sealing barriers mounted above the lowermost bushing element. In accordance with a specific feature of the invention, the lowermost bushing element comprises a heat and corrosion resistant material and is formed to include an internal fluid chamber arranged to provide a fluid reservoir around the valve stem. Pursuant to an additional embodiment of the invention, a cartridge element is arranged and configured to house and enclose the sealing barriers, whereby the cartridge element and enclosed sealing barriers comprise an integral unit.

Abstract: A steam desuperheater comprising a liquid spray tube assembly positioned in a steam line and including a plurality of liquid outlet openings supplying liquid to plural spray nozzles, and a hollow piston plug axially movable therein upwardly from a lower valve seat to progressively open said outlet openings.
