Abstract: A water heater apparatus (27) is shown which includes a water heating tank (29) having generally cylindrical sidewalls with upper (31) and lower ends (33), each of which is closed by a transverse wall section (35) to define a closed tank interior.      The tank also has a water inlet (41) and a water outlet (43). A plurality of vertically arranged fire tubes (45) are connected between the upper (35) and lower (37) transverse wall sections, each fire tube having an open interior for conducting products of combustion. A combustion chamber (53) is mounted on the upper end of the water heating tank for providing products of combustion to the open interiors of the fire tubes. A flue collector (63) is located at the bottom end of the tank for collecting and exhausting the products of combustion from the vertically arranged fire tubes. An induction blower (65) draws the products of combustion downwardly from the combustion chamber, through the fire tubes and out the flue collector for exhaustion from the apparatus. A specially designed burner (57) operates at lower pressure conditions and provides a low capacity airflow to the unit when the main induction blower is off to create a static condition and prevent condensation within the internal components of the apparatus.

Abstract: A ferritic non-ridging stainless steel and process therefor. A chromium alloyed steel melt is deoxidized with a sub-equilibrium amount of titanium and nitrogen and continuously cast into a strip or a slab or cast into an ingot having an as-cast fine equiaxed microstructure substantially free of columnar grains. The as-cast steel contains 0.010% Al, up to 0.08% C, 0.10-1.50% Mn, <= 0.05% N, <= 1.5% Si, 8-25% Cr, < 2.0% Ni and is deoxidized with titanium, all percentages by weight, the balance Fe and residual elements. Preferably, the titanium is controlled so that (Ti/48)/[(C/12)+(N/14)] > 1.5. A hot processed continuous sheet may be formed from a continuously cast slab without surface grinding, may be descaled, cold reduced to a final thickness and recrystallization annealed. An anneal prior to cold reduction is not required to obtain an annealed sheet essentially free of ridging.

Abstract: A method and apparatus for testing a plumbing system (20) and for removing obstructions (70) in a plumbing line (44). During the rough-in plumbing phase of construction (Fig. 1), the drain pipe (44, 46, 48) from the plumbing system (20) in a building (22) to the main city sewer line (38) is positively sealed off by a test cap (70) welded in the pipe at the location of the clean-out (56), access to which is maintained through the clean-out (56). Pressurizing the rough-in plumbing to test proceeds. If any leaks occur, they are in the branch plumbing (26) on the building side of the test cap, and not at or in the test cap. Following successful completion of the initial test, the top-out plumbing is completed, leaving the test cap (70) welded in the clean-out (56) or drain pipe (44). After the roof vents are in, the second test of the plumbing system (20) is made. If the system shows any leaks, they are the result of a failure in the plumbing and not a failure of the test cap (70).  After final test and inspection, a special tool or apparatus (100) in accordance with the present invention is inserted down the clean-out (56) to penetrate and ream-out the test cap (70), so that the drain pipe is opened (174) and provides a passageway (180) through which the waste can flow to the sewer line (38).

Filed: 2000-06-13
Granted: 2007-03-27
Abstract: An electrochemical assay includes a method for determining with great accuracy the time at which an applied sample bridges a gap between the electrodes of an electrochemical cell. The method involves applying a constant small current across the gap, while monitoring the potential difference between the electrodes. The time at which the sample bridges the gap is marked by a sharp drop in the potential. A constant voltage is applied after the sample is detected, and the current and/or charge through the sample is monitored over a period of time. From the measured current or charge, the analyte concentration of interest can be calculated.
