Inventor: DELONG DERWOOD S
IPC: A47J37/08
Filed: 1998-03-11
Abstract: A toaster having an electronic circuit including a chip-on-board ASIC that controls the operation of toaster heating elements and an electromagnet to which relatively high voltage is applied to hold an armature carried by a bread carriage and toaster-operating assembly.  The armature is freely suspended from a bread carriage and toaster-operating assembly and accurately guided onto the electromagnet when the bread carriage is lowered.  The toaster has a one-piece main frame that includes both a base frame plate and a rear frame plate.  Several economies are obtained by virtue the construction of the toaster.      A one-piece control support member is mounted on the base frame plate that supports both mechanical and electronic assemblies for controlling the operation of the toaster in predetermined relative positions.  The armature can move upward relative to the bread carriage at the end of a toasting cycle if the bread carriage accidentally becomes stuck so that the power switches will assuredly be opened at the end of toasting cycle.  A barrier is provided between live electricity and the toaster cover.  A crumb tray is provided that may be mounted on the base frame member without the use of tools or additional parts.

Patent CA-2237853-A1 (CA)
Inventor: SCHYRA MICHAEL
IPC: A61M11/00
Filed: 1996-12-05
Abstract: A spring-actuated output drive device is used for example in medical aerosol therapy for a miniaturised high-pressure producing device for atomising a small dose of a liquid medicament. A locking stressing mechanism for such an output drive device is to be stressed with the application of a relatively small amount of force and is to be released with one hand and is to operate reliably over a prolonged period of time. The locking stressing mechanism comprises a force step-up transmission means, for example a screw thrust transmission means, for stressing the spring, an annularly arranged locking member with engaging locking surfaces, two abutments for limiting the travel of the spring and a release button. It is compact, economical to produce, easy to assemble and comprises components with a low rate of wear. It can be reliably and easily handled by unskilled persons, even when high spring forces are involved. A medicament to be atomised can thus be metered with a very high degree of accuracy.
Patent CA-2240411-A1 (CA)
Title: Flameless combustor
Inventor: WELLINGTON SCOTT LEE
IPC: A47G25/90
Filed: 1996-12-17
Abstract: A combustor method and apparatus is provided. The method utilizes flameless combustion with one or more of three improvements to enhance ignition of the flameless combustor. A catalytic surface can be provided within a combustion chamber to provide flameless combustion at least in the vicinity of the catalytic surface at a temperature that is much lower than the autoignition temperature of fuel in air without the presence of the catalytic surface. Nitrous oxide or supplemental oxygen may also be used as an oxidant either instead of air or with air to reduce ignition temperatures. Further, electrical energy can be passed through the fuel conduit, raising the temperature of the conduit to a temperature above which the fuel will ignite when combined with the oxidant.

Abstract: A power supply with an input protection circuit is disclosed. The protection circuit includes a thermistor that heats up if the power supply is mistakenly connected to an excessive input voltage.  When the thermistor gets hot, its resistance increases, and isolates the down stream portion of the power supply from the input voltage.  A relay in parallel with the thermistor is closed, thus shorting the thermistor, after a preset time if the input voltage had a proper magnitude.

Patent CA-2251434-A1 (CA)
Inventor: HUDSON CHRISTOPHER ALLEN
IPC: H05B41/04
Filed: 1998-10-22
Abstract: An ignitor and ignitor monitoring device is provided which is externally and detachably mounted to a high intensity discharge (HID) luminaire. The ignitor monitoring device provides a visual indication of whether or not the ignitor of the lamp in the HID luminaire is functioning. If the lamp is not on and the indicator is activated, sufficient open circuit voltage is present to operate the ignitor, the ballast in the luminaire is most likely functioning properly, and power is present to operate the luminaire. A service person can assume that he lame is defective and can replace the lamp as a first attempt to correct the problem with the luminaire. If the lamp is off and the indicator is also not operating, the luminaire is not operating for any of a number of reasons such as a defective ignitor, a defective ballast capacitor, a defective lamp or loss of supply voltage from the power source. A service person can replace the ignitor in a first attempt to repair the luminaire. Replacing the ignitor is the simplest initial repair option since the ignitor is externally mounted on the luminaire.

Patent CA-2274014-A1 (CA)
Title: Method for simultaneously controlling and programming a plurality of transponders and device for implementing this method
Inventor: DERTADIAN SAAK
IPC: G06K17/00
Filed: 1997-12-04
Abstract: The method involves using an external transmitter to transmit energy (1) to a group of read and write transponders. After a time delay (TRR) the transponders emit identification signals (2-3,4-5) through allocated time windows. An external receiver receives the signals during the first window and determines if there is dispersion. If there is dispersion the supply of transmitted energy is interrupted quickly enough to deactivate all the transponders. Energy transmission is resumed and if no transponder signal dispersion is now detected, a window of reception is used to send groups of data to the transponders which are simultaneously programmed into their memories.

Title: Printing multiple page documents including variable data
Inventor: KOLNIAK THOMAS P
IPC: G06K15/00
Filed: 1998-01-15
Abstract: A system and method are provided which have the ability to print whole documents at a time, rather than page by page. The data for an entire multi-page document is fed directly to an output device, and then a print engine. The data stream includes a record layout including data field codes which tell the data system and/or raster image processor where to print strings of variable information in a document so that the strings only need be provided once even if printed in multiple places within the document.      Data flows in the data stream to the print engine as the raster image processor functions in real time. The system has the capability to manipulate and transfer data at 10 Mbytes per second, which translate into a transfer rate of approximately 92,000 characters per second at up to 1,000 fet per minute print speeds, for up to six controllers. Either fixed or variable graphic elements may also be transferred in this same manner as the data and processed by the RIP in real time and printed at the same speed as the data.

Abstract: An integrated computer-implemented corporate information delivery system. A  database stores research reports produced by and received electronically from brokerage firms. The database also stores corporate information about a number of corporations. Each item of corporate information is produced by and received electronically from one of the corporations about that corporation. Authorization information ("entitlements") specifies who is authorized to access each research report or item of corporate information. An entitlement subsystem allows the contributor of the research report or item of corporate information to dynamically change, on-line, the entitlement status of any or all users/subscribers. A reserach delivery module allows a user to submit a query and receive query results listing research reports and corporate information satisfying the query and that the user is authorized to access. A corporate register module outputs corporate information, the corporate information output according to a common format. The corporate information may be distributed via the Internet.
