Title: Method for recycling iron bearing sludges in a steelmaking operation
Inventor: SMITH COLVIN W
IPC: C22B7/04
Filed: 1998-01-22
Abstract: The invention is directed to a process for dehydrating wet BOF scrubber sludge to produce a steelmaking revert having an improved flow rate when handled in a recycle stream. Wet sludge is combined with hot BOF slag to provide a slag/sludge mixture. The wet sludge causes the mixture to have a moisture content greater than 10 % water by weight, and the hot slag, having a temperature below the molten liquid state, vaporizes the water in the mixture and reduces the moisture content to about 4 % water by weight or less. The dehydrated mixture has improved flow rate properties when it is recycled as a steelmaking revert.

Title: Ink supply device and ink key thereof
Inventor: KIHARA TERUAKI
IPC: B41F31/04
Filed: 1999-09-09
Abstract: The present invention relates to an ink supply device and an ink key thereof and makes it possible to stabilize the action of the ink key and to save labor in cleaning of the ink key by preventing the ink from getting into a gap between the neighboring ink keys. A cover member hermetically covering the surfaces of a plurality of ink keys is mounted in an ink box to reduce an area where the ink keys are in direct contact with the ink and a groove is made on one or both of the sides of each of the plurality of neighboring ink keys covered by the cover member from the top surface of the ink key to the bottom surface thereof, and even if the ink leaks and gets into a gap between the ink keys because of capillary phenomenon, the groove prevents the ink from spreading along the gap between the reminder of the ink keys.

Title: Security door lock arrangement
Inventor: FROMBERG SIDNEY
IPC: G08B13/08
Filed: 1998-03-26
Abstract: A security lock arrangement for a door type structure includes a latch (14, 34) extending between the movable door (12) and the fixed door jamb (18). A magnet (36) is contained within a magnet receiving cavity (38) located within the latch. A reed switch (30) is positioned within a switch receiving cavity (28) located adjacent to the latch member receiving cavity (24) located in the door jamb. When the magnet is located within the latch member receiving cavity after displacement of the latch to secure the door in a closed position within the door jamb, the reed switch is activated. When the magnet is moved out of switch operating relationship with respect to the reed switch, which occurs prior to the door being opened, the change in the magnetic flux causes the reed switch to generate an information signal which indicates that an attempt has been made to open the door.

Patent CA-2290242-A1 (CA)
Title: Auto-correlation system and method for rate detection of a data communication channel
Inventor: PRASAD MOHIT KISHORE
IPC: H03M13/41
Filed: 1999-11-23
Abstract: Rate detection of a data rate within a sequence of transmitted symbols employs correlation to calculate estimates of the auto-correlation values, or estimated coefficients, of the sequence. When the sequence of transmitted symbols includes repeated symbol values, the auto-correlation values indicate a degree of self similarity within the sequence. A decision statistic may be formed from the auto-correlation values. The self similarity of the auto-correlation values may be employed as a decision statistic with associated hypothesis test pair values.  Various decision methods may be implemented to compare auto-correlation values to thresholds based on the hypothesis test pair values. Based on the comparison, the data rate of the sequence may be determined. Once the information is determined related to the data rate, the information may be employed by a Viterbi detector to adjust the decoding rate for decoding the symbols.

Patent CA-2293634-A1 (CA)
Title: Non-stalled requesting texture cache system and method
Inventor: ZHAO RANDY
IPC: G06T15/00
Filed: 1999-03-04
Abstract: A caching system for increasing the operation concurrency between a cache module (130) and a memory module (140) by comparing received memory block identifiers, which correspond to texels needed for pixel composition, with memory block identifiers corresponding to texels locally stored within the cache module. If the received memory block identifiers match the memory block identifiers corresponding to locally cached texels, the system transmits these texels to a texture filter unit (180) for pixel composition. If the received memory block identifiers do not match memory block identifiers corresponding to the locally cached texels, the system retrieves these texels from the memory module as fast as possible and then updates the cache module with the new texels. A  plurality of FIFOs are used to assist a controller module with synchronizing the transmission of the texels from the cache module and the overwriting of the texels received from the memory module into the cache module. Once locally cached, these texels also are transmitted to the texture filter unit for pixel composition.
Patent CA-2302604-A1 (CA)
Title: Method of communication with a transportation system
Inventor: FRIEDLI PAUL
IPC: B66B3/00
Filed: 2000-03-28
Abstract: This human-machine interface has a touch screen (1) with a selection of travel destinations at, for example, a university which can be individually selected by touching the screen. The travel destinations are not represented as real locational parameters such as a floor number, for example, but by means of designations. The user selects, for example, the conference room as his travel destination without knowing where the conference room is actually located. A control determines the real locational parameter by means of a table in which, for example, the real locational parameter "Floor 23" is assigned to the designation "Conference Room". The control assigns the desired floor to the elevator car with the best travel conditions and informs the user on the touch screen (1). The information contains the designation of the means of transportation and an indication of the place of boarding.

Title: Double-tube type heat exchanger and refrigerating machine using the heat exchanger
Inventor: YONEDA YUJI
IPC: F25B1/00
Filed: 1999-07-22
Abstract: A double-tube type heat exchanger has a restriction hole, formed on an inner tube, through which a refrigerant introduced into an outer tube is introduced into the inner tube while the refrigerant expands. Therefore, a part of the refrigerant introduced into the outer tube can be introduced into the inner tube from the restriction hole while the refrigerant expands. That is, the restriction hole formed on the inner tube serves as an expansion mechanism of a bypass flow. Therefore, this double-tube type heat exchanger allows an injection circuit or a super-cooling circuit to be compactly and inexpensively constructed.

Patent CA-2312269-A1 (CA)
Inventor: SHIBUYA HISASHI
IPC: C12Q1/68
Filed: 2000-07-20
Abstract: The invention overcomes deficiencies in the prior art by identifying a locus associated with average weaning weight and carcass weight of cattle. The locus was found during studies carried out by the inventors using a polymorphic TG-repeat microsatellite located 90 base pairs upstream from a major transcription start site in the bovine growth hormone receptor gene. Use of this marker and other genetic markers in linkage disequilibrium with the locus allows implementation of selection and breeding schemes for improvement of cattle performance. Marker-assisted selection with the genetic markers will allow avoidance of potentially costly phenotypic testing associated with traditional breeding schemes.

Title: Sound signal processing method and sound signal processing device
Inventor: TASAKI HIROHISA
IPC: G10L21/0364
Filed: 1998-12-07
Abstract: A sound signal processing method and a sound signal processing device for processing an input sound signal including deteriorated sound such as quantizing noise so that the deterioration sound may be hardly heard subjectively. After the spectrum of a decoded sound which is an input sound is auditorily weighted, the spectrum is calculated by a deformation strength control unit, and the deformation strength is calculated based on the amplitude and continuity of the spectrum. The spectrum of the decoded sound is found by a signal deformation unit. Then the amplitude is smoothed, phase disturbance is imparted in accordance with the deformation strength, and the decoded sound is returned to a signal region as a deformed decoded sound. The decoded sound is analyzed, and the background noise likeness is calculated by a signal evaluating unit and used as an addition control value. If the addition control value shows the background noise likeness, a weighted addition unit reduces the weight upon the decoded sound, increases the weight upon the deformed decoded sound, and performs addition to generate an output sound.
