Title: Horizontal hid vehicle headlamp with magnetic deflection
Inventor: ROTHWELL HAROLD L
IPC: H01J61/50
Filed: 1999-01-22
Abstract: The efficiency of a horizontally operated arc discharge lamp has been found to be substantially improved by the application of a transverse magnetic field. The magnetic field moves the arc downward, away from the upper wall of the lamp envelope. The magnetic field moves the arc so that the outer mantel that otherwise would make contact with side walls of the envelope stand away from the envelope wall.      With the arc withdrawn from the wall, less energy is lost in heating the envelope, resulting in more energy be directed to the emission of light.

Title: Bread making machine and method with automated dispenser and pause function
Inventor: SIT MICHAEL
IPC: A21B7/00
Filed: 1997-07-23
Abstract: A bread making machine having an automated dispenser unit and a pause function is described.       The automated dispenser unit is integrated within a chamber lid covering a bread making chamber in which bread making ingredients are mixed, kneaded, and baked. The automated dispenser accepts certain ingredients, such as fruit and/or nuts, which are automatically added to the bread making chamber after significant processing of other ingredients in the bread making chamber has occurred.      The automatic dispenser unit includes a dispenser door adjacent to the bread making chamber. The dispenser door is held in a closed position by a latch assembly. The latch assembly is mechanically linked to a solenoid core, which moves in response to a control signal issued by electronic control circuitry, causing the dispenser door to open.      The bread making machine includes a pause function, which allows a user to temporarily suspend the bread making operation at any time, by pressing a pause key on a user interface keyboard. The bread making operation resumes after a selected time interval has elapsed. The selected time interval may be determined either by the user or by the electronic control circuitry.

Abstract: Methods and apparatus for screening diverse arrays of materials using infrared imaging techniques are provided. Typically, each of the individual materials on the array will be screened or interrogated for the same material characteristic.      Once screened, the individual materials may be ranked or otherwise compared relative to each other with respect to the material characteristic under investigation. According to one aspect, infrared imaging techniques are used to identify the active sites within an array of compounds by monitoring the temperature change resulting from a reaction. This same technique can also be used to quantify the stability of each new material within an array of compounds. According to another aspect, identification and characterization of condensed phase products is achieved, wherein library elements are activated by a heat source serially, or in parallel. According to another aspect, a Fourier transform infrared spectrometer is used to rapidly characterize a large number of chemical reactions contained within a combinatorial library.
Patent CA-2269337-A1 (CA)
Inventor: WOOLLARD DOUGLAS J
IPC: B05B3/10
Filed: 1999-04-15
Abstract: Application of a release agent onto the interior surfaces of a commercial bakery trough is accomplished by a system for dispensing a gel having two spray head assemblies. While the trough is stationary, each head in turn descends into the trough and propels the release agent onto a portion of the interior surfaces including side walls, an end wall, and the bottom wall of the trough. Each head includes a disc that spins to distribute the release agent. An edge on the disc defines a predetermined spray pattern. Waste of release agent due to overspray is minimized by controlling a release agent valve in the head, controlling disc rotation, and monitoring position of the head in the trough.

Title: Laser with two orthogonal zig-zag slab gain media for optical phase distortion compensation
Inventor: ST PIERRE RANDALL J
IPC: H01S3/042
Filed: 1999-04-15
Abstract: An optical amplifier for use with a solid state laser which includes a pair of elongated slabs of a solid state lacing material, such as a rare earth doped yttrium-aluminum-garnet (YAG) crystal. Two embodiments of the invention are disclosed. In both embodiments of the invention, each of the elongated slabs is formed with a square or generally rectangular cross-section. The slabs are configured such that the longitudinal axes of the slabs are generally co-axial aligned and the slabs are orientated such that the major axis of the slabs are generally orthogonal. By configuring the two slabs to be orthogonal with respect to one another, the integrated thermal lens becomes azimuthally symmetric and can be compensated by a simple external lens. In addition, the negative lensing affect along the major axis of one slab is used to compensate for the positive lensing affect along the minor axis of the other slab and vice versa, thus minimizing the affects of the astigmatism. In an alternate embodiment of the invention, a dove prism is used to rotate the beam instead of rotation of the slabs.

Title: Plate diffuser for treating comminuted cellulosic fibrous material
Inventor: PROUGH JAMES R
IPC: D21C9/04
Filed: 1999-05-07
Abstract: The problems of non-uniform treatment of paper pulp that may be caused by differential flow velocities within a vessel, channeling, and/or disruption of the pulp flow, are substantially eliminated by providing a non-circular cross-section substantially atmospheric pressure vessel with at least one screen surface, and typically a liquid introducing device. The vessel, screen surface, and liquid introducing device are constructed and positioned with respect to each other so that during the treatment of a pulp slurry the slurry has substantially uniform width in a treatment zone, and there is substantially uniform resistance to the flow of slurry over the screen surface over any particular cross-section of the vessel in the treatment zone, and its consistency varies less than 6% in the treatment zone (e.g. between 8-14%). The screen surface may comprise substantially vertical screening portions vertically spaced by non-screening portions, and the vessel wall may bulge out at the location of the non-screening portions so as to provide a slurry width at the bulges at least five percent wider than at the screening portions. The vessel may have a substantially race track shape in cross-section at the treatment zone, and the slurry width may form an annulus in the vessel, the annulus being substantially uninterrupted in the treatment zone (there being no arms or like structures which disrupt the flow). The screen surface may be rotated 5-30°, or oscillated or vibrated horizontally (transverse to pulp movement) to minimize plugging.

Title: Gps and cellular system interworking
Inventor: STEER DAVID G
IPC: G01S19/41
Filed: 1999-05-14
Abstract: Aspects of global positioning system (GPS) technology and cellular technology are combined in order to provide an effective and efficient position location system. In a first aspect of the invention, a cellular network is utilized to collect differential GPS error correction data, which is forwarded to a mobile terminal over the cellular network. The mobile terminal receives this data, along with GPS pseudoranges using a GPS receiver, and calculates its position using this information.  According to a second aspect, when the requisite number of GPS satellites are not in view of the mobile terminal, then a GPS pseudosatellite signal, broadcast from a base station of the cellular network, is received by the mobile terminal and processed as a substitute for the missing GPS satellite signal. A third aspect involves calculating position using GPS when the requisite number of GPS satellites are in view of a GPS receiver, but when the requisite number of GPS satellites are not in view of the GPS receiver, then position is calculated using the cellular network infrastructure. When the requisite number of GPS satellites come back into view of the GPS receiver, then position is again calculated using GPS. A fourth aspect involves using cellular signals already being transmitted from base stations to terminals in a cellular network to calculate a round trip delay, from which a distance calculation between the base station and the terminal can be made. This distance calculation substitutes for a missing GPS satellite signal.
