IPC: F24H1/18
Filed: 1993-04-14
Abstract: An improved water heater is shown which includes a water heating tank having external cylindrical sidewalls, an interior, and initially open upper and lower ends. A combustion chamber is connectable to the water heating tank and houses a burner for the combustion of a selected fossil fuel. A fire tube unit of a fixed length is received within the interior of the water heater tank and has an upper transverse wall section, a lower transverse wall section and interconnecting fire tubes. The fire tubes have open interiors which receive the products of combustion from the combustion chamber for heating water contained in the water heating tank. Flanges and resilient seals are located at the upper and lower ends of the water heating tank for securing the fire tube unit within the interior thereof. The resilient seals can be selectively sized to accommodate dimensional tolerances which occur between the fixed length of the fire tube unit and the water heater tank, allowing the components to be assembled in modular fashion.

Title: Device and method for repairing building branch lines in inaccessible sewer mains
Inventor: SIGEL ALWIN
IPC: F16L55/16
Filed: 1992-07-23
Abstract: Abstract The invention involves a device and a process which can be employed forsealing building branch lines (3b) leading from a building or a collecting manhole directly to a sewer mains (4) using a relining process in which inliners (1) made of self-hardening/self-curing sealant are used. In the process according to the invention, a pipe repairing machine (6) is employed which features a rope guiding device (10) at its front end (14), said rope guiding device (10) being comprised of a roller mount (15) to which a deflection pulley (5) and a retaining roller (16) are affixed. The pipe repairing machine (6) into whose rope guiding device (10) the rope (7) to which the inliner (1) is attached is threaded is positioned inside the sewer mains (4) at the building branch line junction (2) in such a manner that the rope (7) does not come into contact with the building branch line edge (9) facing the pipe repairing machine (6) when taut. While the rope (7) is being pulled through the building branch line (3b), a support foot (11) with a brake block (12) ensures that the pipe repairing machine (6) does not shift.

Patent CA-2119741-A1 (CA)
Inventor: POTTER MARK J
IPC: B01J38/72
Filed: 1992-09-30
Abstract: Processes for washing zeolites, preferably less than about 0.5 micron in size, with a microfiltration system employing a washing liquid, such as an aqueous solution or water (preferably deionized water), to produce zeolite crystals having a zeolite pH in the pH range of 9.4 o 10.0 are provided. The zeolite pH is determined by a special procedure. The preferred washing processes include slurring the zeolite crystals with water (or an appropriate wash solution), initially concentrating the slurry with a microfilter to a preselected initial concentration, washing the crystals by adding make-up water at the same rate as the fluid loss due to permeate flow until the permeate pH is below a preselected value, then stopping the make-up flow and concentrating the slurry to a preselected maximum final concentration. A sample of the zeolite is dried and tested for its pH and if within the desired range, the batch of maximally concentrated slurry is dried. These processes are employed to produce zeolite crystals having a zeolite pH      of about 9.4 to 10Ø
Patent CA-2125537-A1 (CA)
Inventor: MARCUS SANFORD M
IPC: G01N25/20
Filed: 1994-06-09
Abstract: The present invention is a method and apparatus for measuring the thermal conductivity of materials using modulated differential scanning calorimetry (MDSC). Two MDSC heat capacity measurements are made consecutively. One measurement is made under conditions which ensure obtaining a fairly accurate value for the heat capacity of the material. Another measurement is made under conditions such that the measured effective heat capacity differs from the accurate value of the heat capacity due to thermal conductivity effects. The thermal conductivity of the material is then calculated.      For example, a large sample and a small sample of the material whose thermal conductivity is to be determined are prepared with different sample geometries. The specific heat of the small sample and the effective heat capacity of the large sample are the measured using MDSC. The thermal conductivity of the material is then calculated from these measured values, using equations derived from the one-dimensional thermal diffusivity equation. In one embodiment of the invention, increased accuracy is achieved by measuring the thermal conductivity of a sample of a material having a known thermal conductivity, and then calculating a correction factor that can be applied to all samples having similar dimensions. In another embodiment of the invention, the thermal conductivity of a thin film is measured by placing a thin film on the sample position and using MDSC to measure the effective heat capacity of a cylinder placed on top of the thin film. The thermal conductivity of the sample is then calculated from the measured effective heat capacity of the cylinder, the known true heat capacity of the cylinder, and the dimensions of the cylinder.
