Patent CA-2325988-A1 (CA)
Title: Apparatus for regulating heater cycles to improve forced-air heating system efficiency
Inventor: HAMMER JACK
IPC: F23N1/00
Filed: 1999-03-25
Abstract: A method and apparatus of regulating cycles of a burner in a forced air heating system. A control unit uses a sensor at an output of a heat exchanger to make measurements of a temperature of air output from the heat exchanger. The control unit observes temperature measurements, after the burner has turned on. It initializes a confirmation interval when two consecutive temperature measurements are the same, if the temperature is the same at an end of the confirmation interval.  The invention interrupts firing of the burner for an interrupt interval. The interrupt interval is insufficient to allow the heat exchanger to cool below a temperature useful for heating below which the circulation fan would shut off.

Patent CA-2329418-A1 (CA)
Inventor: ASPLIN JOHN ERNEST
IPC: C10G51/02
Filed: 1999-04-27
Abstract: A two stage process for selectively producing C2 to C4 olefins from a gas oi l or resid. The gas oil or resid is reacted in a first stage comprised of a fluid catalytic cracking unit wherein it is converted in the presence of conventional large pore zeolitic catalyst to reaction products, including a naphtha boiling range stream. The naphtha boiling range stream is introduced  into a second stage comprised of a process unit containing a reaction zone, a stripping zone, a catalyst regeneration zone, and a fractionation zone. The naphtha feedstream is contacted in the reaction zone with a catalyst containing from about 10 to 50 wt.% of a crystalline zeolite having an avera ge pore diameter less than about 0.7 nanometers at reaction conditions which include temperatures ranging from about 500 to 650 ~C and a hydrocarbon partial pressure from about 10 to 40 psia. Vapor products are collected overhead and the catalyst particles are passed through the stripping zone on  the way to the catalyst regeneration zone. Volatiles are stripped with steam  in the stripping zone and the catalyst particles are sent to the catalyst regeneration zone where coke is burned from the catalyst, which is then recycled to the reaction zone.

Title: Nasal sprayer with folding actuator
Inventor: DEJONGE STUART
IPC: A61M15/08
Filed: 2001-01-11
Abstract: A nasal pump sprayer having a folding actuator that can be used as a dust cover, finger grip and shipping clip. The folding actuator has a pair of wings that are hingedly connected to the pump body of the nasal pump sprayer and which can be locked in a closed position and used as a cover and shipping stop. The wings may also be opened to a lateral position and used as finger grips for actuating the nasal pump sprayer. Each wing has a locking means at one end for snap-locking the wings together and a hollow interior that is complementary in shape to the nozzle of the sprayer. An immobilizing means extends from the connected end of each wing and engages a confronting edge of the pump body thus locking the plunger head of the nasal pump sprayer against reciprocation for storage and shipping.

Patent CA-2331914-A1 (CA)
Title: Optical fiber gratings having internal gap cladding for reduced short wavelength cladding mode loss
Inventor: STRASSER THOMAS ANDREW
IPC: G02B6/02
Filed: 2001-01-23
Abstract: The present invention is predicated on applicants' discovery that an appropriately spaced and dimensioned internal gap cladding can substantially reduce short wavelength cladding mode loss in a fiber Bragg grating. A fiber Bragg grating is provided with a ring of closely spaced, longitudinally extending gap regions in the glass peripherally surrounding the core. The gaps are spaced apart by thin glass webs having a thickness less than a wavelength of the light being transmitted and are disposed peripherally about the core at a distance of 2-10 wavelengths from the core center. The thin webs limit the passage of the light between the gaps. The combination of webs and gaps acts as an internal thin cladding which supports fewer cladding modes than conventional glass cladding and, significantly, provides increased wavelength spacing between the Bragg resonance and the first cladding made resonance.

Patent CA-2341106-A1 (CA)
Title: Portable, potable water recovery and dispensing apparatus
Inventor: FORSBERG FRANCIS C
IPC: E03B3/28
Filed: 2001-03-20
Abstract: A portable, potable-water generator for producing high-purity liquid water by condensation of dew from ambient air. The generator employs an air fiter to remove particulates and aerosols from the incoming air. An enclosed heat absorber cools the filtered air to its dew point and collects droplets of condensate into a combined condensate collector and storage reservoir. Before discharge, the collected dew is treated in a bacteriostat loop to destroy adventitious living organisms and to filter out undesirable and dangerous contaminants. A recirculation loop provides the ability to recirculate stored condensate during periods of inactivity. Further, quick disconnect fittings and variable length flexible tubing allows use of the invention to serve remote dispensers and/or appliances and allows use of municipal water treated through the apparatus in low condensate situations. All the subsystems are fail safe-interlocked to disable the generator immediately and prevent delivery of water if any one of them stops functioning within predetermined safe limits.

Title: Objective lens inclinable to correct for a third-order coma aberration and an optical head device including the same
Inventor: TANAKA YASUHIRO
IPC: G11B7/00
Filed: 2000-07-27
Abstract: An objective (1) for optical disks for focusing the beam of light from a lig ht source. The third-order comatic aberration of the objective of when an optic al disk (2) inclines at a unit angle is larger than that of when the objective inclines at a unit angle. The objective is mounted on an actuator that inclines the objective according to the inclination of the optical disk. Therefore the numerical aperture of the objective is large. The manufacture and assembly of the objective are facilitated. The third-order comatic aberration caused when the optical disk inclines because of its warp can be corrected by inclining the objective, thereby decreasing the residual astigmatism after the correction.
