Patent CA-2574075-A1 (CA)
Inventor: BOSSUYT COREY
IPC: E03B5/02
Filed: 2007-01-10
Abstract: Auxiliary water is supplied to a building, which also receives water from a main supply line, from an external portable tank separate from the main supply line. The water is pumped from the tank through an auxiliary supply line to a junction with the main supply line. One-way valves are provided in both the main supply line and the auxiliary supply line before the junction to prevent backflow in each of the supply lines from the other supply line. Water is pumped to the auxiliary supply line at a prescribed pressure which is less then the main supply line pressure so that the valves allow water to be drawn only from the main supply line until a loss of main line pressure at which point the valves automatically cause the greater auxiliary supply line pressure to cause water to be drawn only from the auxiliary supply line.

Title: Low temperature fired, lead-free thick film heating element
Inventor: BARROW DAVID ANDREW
IPC: H05B3/16
Filed: 2006-07-18
Abstract: A lead free, thick film heating element. Known thick film heating elements contain environmentally hazardous material such as lead. This is particularly problematic when manufacturing thick film heating elements, as lead is often used in thick film formulations to allow the glass-based thick film to be processed at low firing temperatures. Using composite sol gel technology, the present invention provides a method to produce a lightweight mica-based thick film heating element based on thick film materials that are free from lead or cadmium. This mica-based element is lightweight, has the performance advantages of a thick film heating element, and may be processed at a low temperature using thick film materials. Particularly, the present invention provides a lightweight heating element comprised of a mica-based substrate material, a resistive thick film that can be produced by composite sol gel technology, optionally a conductive thick film which is used to make electrical connection to the resistive element, and optionally a topcoat which is used to provide protection against moisture and oxidation. This element is lightweight, provides efficient, rapid heat up and cool down, can be designed to provide even temperature distribution, and delivers power at lower operating temperatures resulting in increased element safety.
