Patent CA-2121616-A1 (CA)
Title: Indirect heater
Inventor: DIXON JAMES M
IPC: F24H3/08
Filed: 1994-04-19
Abstract: An indirect heater for heating air to be used for drying, curing or heating having an enclosure housing a circulation fan, filter bank, heat exchanger module and a burner. The heat exchanger has a bundle of tubes received between a pair of spaced apart headers. A cylindrical burner tube extends through one header and the tube bundle and opens into the other header. The burner flame and gaseous combustion products are discharged into a replaceable sacrificial sleeve that is telescopically received in the burner tube. A fan recirculates the heated gases through the interior of the sleeve, burner tube and the tubes of the bundle to increase heat transfer to the exterior air. The enclosure has a base, two pairs of opposed sidewalls and a top wall overlying the sidewalls. Each sidewall has an inner skin, a framework of trusses, an outer skin and insulation between the skins. The inner skin consists of airtightly joined skin panels supported by the frame and which have expansion gaps between adjoining skin panels to permit thermal expansion and contraction. The outer skin has interlocking panels held in place without contacting directly the frame or inner skin for minimizing heat transmission through each sidewall.

Title: Improved method for supervising tdma radio frequency communications
Inventor: CAHILL STEPHEN V
IPC: H04W74/04
Filed: 1994-05-27
Abstract: A unique method for supervising a cellular telephone call between a base station and a radio telephone of a TDMA cellular communications system includes the steps of detecting the presence of the assigned time slot (306); detecting the presence of the assigned DVCC when the assigned time slot is detected (308); incrementing a bad slot counter (316) if the assigned time slot is not detected or if the assigned DVCC is not detected; and terminating the communication (322) if the bad slot counter reaches a predetermined maximum value. A good slot counter is incremented (310) when the assigned DVCC is detected in a burst. The good slot counter is reset (318) if the assigned DVCC is not detected in the next burst, and both counters are reset (314) if the assigned DVCC is detected in consecutive bursts.
Patent CA-2126738-A1 (CA)
Title: Oxidizing gas detector paper
Inventor: NAKANO NOBUO
IPC: G01N21/78
Filed: 1994-06-24
Abstract: A sheet of paper is immersed in a reacting solution prepared by dissolving p-n-butoxyaniline, an ultraviolet absorber and polyalcohol in an organic solvent. Then, the organic solvent is allowed to evaporate. Thus, the p-n-butoxyaniline and ultraviolet absorber are spread over the sheet of paper by using the water absorbed in the polyalcohol that serves as a medium for reaction. When the paper is exposed to chlorine or other oxidizing gas, the p-n-butoxyaniline colors, aided by the water absorbed in the, polyalcohol, to form a trace of reaction according to the concentration of the oxidizing gas. Because the ultraviolet absorber prevents the reaction between the p-n-butoxyaniline and light, no discoloration-induced sensitivity drop occurs during storage.

Title: A dual flush system for a toilet tank
Inventor: ZAMUDIO-CASTILLO MARIO-RODOLFO
IPC: E03D1/14
Filed: 1995-05-31
Abstract: A dual flush system for a toilet tank, to choose a desired flush volume of water from said tank to flush solids or liquids, depending on the operation of a two-position flush lever, comprising: a latching plate coupled to the overflow tube, having a latching aperture and a tilting gate connected to the flush lever mechanism; a secondary buoyant float slide retained by the overflow tube, having a latch member coupled thereto and connected to the flush lever, passing through the aperture of the latching plate; and a shoe rod coupled to said secondary buoyant float to push the stopper when it is discharging a first volume of water to flush liquids from the toilet bowl. For flushing solids, the flush lever is operated to a first intermediate position, lifting only the stopper causing a total flush of water because the latch member is latched by the tilting gate of the latch plate and the buoyant float as well as the shoe rod remain inoperative. When flushing liquids, the flush lever is operated to a second position lifting the tilting gate releasing the latch member allowing the secondary buoyant float to fall down together with the shoe rod to push the stopper impeding a total discharge of water.
