Title: Continuously operating liquid-cooled panel
Inventor: MCVICKER RICHARD W
IPC: F27D1/12
Filed: 1998-03-03
Abstract: A dual section liquid-cooled panel (10) having a primary section (12) and a secondary or back-up section (14) adjacent to the primary section (12) lines a portion of the interior surface of a metallurgical furnace. A three-way valve controls the flow of fluid to the operating section (12, 14) of the panel (10). Initially, the primary section (12) is operational and the valve is set to permit the flow of fluid to the primary section (12). If the primary section (12) suffers structural damage, the valve can re-direct the cooling fluid to the secondary section (14). The secondary section (14) becomes operational until regular maintenance is scheduled for the furnace.

Title: Portable terminal with advertisement medium
Inventor: KAWAI EIJI
IPC: H04N5/44
Filed: 2000-01-04
Abstract: A portable telephone set or a portable terminal connected to an entertainment apparatus functions as an advertisement medium. When calendar information and time information based on a real-time clock are displayed on a display screen of a portable terminal, advertisement information supplied via radio waves and received by an antenna is simultaneously displayed. Since the advertisement information is displayed simultaneously with the calendar and time information which draws much attention of the user, i.e., which is frequently viewed by the user, the portable terminal can function as a highly effective advertisement medium.

Patent CA-2299011-A1 (CA)
Title: Plastic article consisting of several materials as well as method for the manufacture thereof
Inventor: HEHL KARL
IPC: B29C45/16
Filed: 2000-02-21
Abstract: A hollow plastic article consisting of several materials has a wall in which the materials are joined together via their contact surface. At the closed lower end (10b) of the plastic article (10) there are sprues (51, 52, 53). Because the lower end (10b) is amorphous inside the wall thickness x in spite of the sprues, a homogeneous structure of the plastic article is achieved.      This can be realized by injection moulding in several steps in mould cavities in which case the injection preferably is carried out with open shut-off nozzle, or when the first material is injected a long sprue stalk is produced in order to keep the closed lower end (10b) amorphous, or to keep any crystalline areas outside the wall thickness (Fig. 2).

Title: Method and apparatus for detection of defects in teeth
Inventor: GARCIA-HECULES JOSE AGUSTIN
IPC: A61B5/00
Filed: 2000-07-28
Abstract: There is provided a metrologic methodology and instrument, useful for a high-spatial-resolution dynamic diagnostic metrology and instrument, which can provide simultaneous measurements of laser-induced frequency-domain infrared photothermal radiometry (FD-PTR) and alternating-current (ac) modulated luminescence (FD-LM) signals from defects and caries in teeth intraorally. The combination of the luminescence and radiometric frequency scan techniques for inspection of defects and caries in teeth involves irradiating the tooth with a modulated (direct-current (dc) to 100 kHz) excitation source (laser) emitting in the near-ultraviolet, visible, or near-infrared spectral range, generating blackbody Planck-radiation (infrared radiometry) and ac luminescence, and comparing the obtained (amplitude and phase) luminescence and radiometric signals to those obtained from a well characterized sample (reference) to provide the clinician with numerical information on the status of a tooth. The method and device is used to scan teeth intraorally to detect caries and classify caries or the integrity of the enamel or cementum surface, classify the health and integrity of the enamel at the base of occlusal fissures, classify the health and integrity of enamel or cementum surface of the tooth and defects around the margins of restorations, locate the presence of cracks on the enamel or cementum surface, and locate and characterize cracks in dentin on prepared teeth.
