IPC: H04B1/69
Filed: 1998-09-29
Abstract: A method for allocating utilization of multiple carriers in a wideband CDMA transmission system first determines the carrier utilization/interference levels for each of the multiple carriers. Based on the carrier utilization/interference level, carrier assignments are allocated on an unequal basis. The allocation of the carrier assignment biases the selection of the carriers away from higher utilized/interfered carriers. An apparatus for implementing the method is also described.

Patent CA-2255918-A1 (CA)
Inventor: SUZUKI YASUNOBU
IPC: H02M5/22
Filed: 1996-06-06
Abstract: An AC/AC converter includes first to sixth AC switches. A series of the first and second AC switches and a series of the third and fourth switches are connected in parallel with each other between both ends of an AC input. One end of the primary winding of a transformer is connected to the node of the first and second AC switches and the other end to the node of the fourth and third AC switches. One end of the secondary winding of the transformer is connected to one end of the fifth AC switch and the other end one end of the sixth AC switch. The other ends of the fifth and sixth AC switches are connected to one of the output terminals and the mid point of the secondary winding to the other. The AC/AC converter further includes a control means which alternately operates a group of the first, third, and fifth AC switches and a group of the second, fourth, and sixth AC switches at a frequency higher than that of the input. The AC input repeatedly and alternately flows through the primary winding of the transformer in different directions at a frequency which is sufficiently higher than that of the AC input. Namely, the AC input is converted into an AC of a higher frequency. An arbitrary voltage proportional to the turn ratio of the transformer appears on the secondary side of the transformer at the higher frequency. On the secondary side, the direction of the AC is again controlled by means of the secondary-side AC switches which operate synchronously with the primary-side AC switches and the waveform of the AC closely resembles or is similar to the original waveform. Since a high frequency is impressed upon the transformer, the size of the transformer is reduced and the efficiency of the transformer is improved.

Title: A video reproduction controller and a storage medium
Inventor: EMOTO MASAKI
IPC: G06F19/00
Filed: 1999-02-03
Abstract: When, during the replay of the VTR, time codes are sent to the control unit and the special part detection device supplies detection data to the control unit, the control section displays an indication of the special parts being detected and the time codes found and transferred at detection time on the display device and the video monitor, and writes the detection data and the corresponding time codes into the memory. Hence, the contents of the special parts detected in the reproduced video (tape scratch, flicker, special pattern or change in average luminance, and the levels of these) and the time codes found and transferred at detection time are stored, thus enhancing the efficiency of the editing of cutting off the special parts.

Patent CA-2262345-A1 (CA)
Inventor: COATES FAITH
IPC: A47J43/20
Filed: 1999-02-09
Abstract: A container/mould constituted of a microwaveable, re-usable, recycleable material for the baking of tortillas and or wraps to create an edible bowl. The invention is directed to the provision of a simple and inexpensive container/ mould which is comprised of certified foodgrade plastics, that can be used in a microwave oven.  The container is configured in a bowl shaped structure that has deeply fluted walls that are inwardly and outwardly curved, and a flat circular base. The container/mould will enable a flat bread created from a variety of flours, but specifically wheat, to be pressed into the bowl which acts as a mould. The uniform temperature distribution created by microwaves essentially reduces the water content in the flatbread which dehydrates the bread in the mould allowing for a hardening of the bread.    Upon removal from the container/mould the flatbread retains the mould shape and can then be used as an edible serving vessel. The dehydrated bread retains the deeply fluted shape of the container/mould and makes an attractive alternative serving presentation for a variety of comestibles.
Patent CA-2263726-A1 (CA)
Title: Transgenic plants expressing cellulolytic enzymes
Inventor: UKNES SCOTT JOSEPH
IPC: C12N9/24
Filed: 1997-09-12
Abstract: The invention provides novel methods of controlling gene expression in plastids, using an inducible, transactivator-mediated system, and plants comprising the novel expression systems. The present invention further describes the production of cellulose-degrading enzymes in plants via the application of genetic engineering techniques. Cellulase coding sequences are fused to promoters active in plants and transformed into the nuclear genome and the chloroplast genome. As cellulases may be toxic to plants, preferred promoters are those that are chemically-inducible. In this manner, expression of the cellulase genes transformed into plants may be chemically induced at an appropriate time. In addition, the expressed cellulases may be targeted to vacuoles or other organelles to alleviate toxicity problems. The present invention finds utility in any industrial process requiring a plentiful supply of cellulases, but particularly finds utility in the conversion of cellulosic biomass to ethanol.

Title: A method for processing refractory auriferous sulfide ores involving preparation of a sulfide concentrate
Inventor: SIMMONS GARY L
IPC: B03D1/00
Filed: 1997-10-23
Abstract: A method is disclosed for processing a gold-bearing refractory sulfide ore (102) by main-taining the ore in a substantially oxygen free en-vironment, preferably beginning with comminu-tion (104) of the ore and ending after a desired final concentrate, enriched in sulfide minerals, is obtained by flotation (112). In one embodiment, nitrogen gas (110) is used to prevent contact be-tween the ore and air during comminution of the ore (108) and during flotation operations (114).      This invention recognizes that gold in refractory sulfide ores primarily occurs in refractory aurifer-ous sulfides, which arc typically the most difficult sulfide species in the ores to float. By reducing the exposure of those refractory auriferous sulfides to oxygen gas during flotation, flotation recovery is enhanced in the form of a flotation concentrate (116). A flotation tail (118) is also obtained from the process.
