Title: Recombinant cells that highly express chromosomally-integrated heterologous genes
Inventor: INGRAM LONNIE O
IPC: C12N15/09
Filed: 1991-12-04
Abstract: Recombinant host cells are obtained that comprise (A) a heterologous, polypeptide-encoding polynucleotide segment, stably integrated into a chromosome, which is under transcriptional control of an endogenous promoter and (B) a mutation that effects increased expression of the heterologous segment, resulting in enhanced production by the host cells of each polypeptide encoded by that segment, relative to production of each polypeptide by the host cells in the absence of the mutation. The increased expression thus achieved is retained in the absence of conditions that select for cells displaying such increased expression. When the integrated segment comprises, for example, ethanol-production genes from an efficient ethanol producer like Zymomonas mobilis, recombinant Escherichia coli and other enteric bacterial cells within the present invention are capable of converting a wide range of biomass-derived sugars efficiently to ethanol.

Patent CA-2102194-A1 (CA)
Inventor: LAROSA CHRISTOPHER P
IPC: H04B7/26
Filed: 1993-01-21
Abstract: The present disclosure includes a discussion of a method of phase adjustment for use in a clock recovery scheme. The phase adjustment circuit automatically holds the clock phase during periods of poor channel quality. The clock recovery scheme generates a sampling clock signal (139) which is synchronous with the received signal (131). Additionally, the clock recovery scheme generates at least two error signals (347, 349, 351, 353) which indicate the quality of the received signal at different sampling phases. The smallest error signal is referred to as the minimum error value. Each error signal (347, 349, 351, 353) is compared to the minimum error value, creating a corresponding normalized error magnitude signal. Each normalized error magnitude signal is processed to determine the desired phase of the sampling clock signal. Dependent upon the processing of the normalized error magnitude signals, the phase of the sampling clock signal is either shifted or maintained until the next sampling point.

Title: Viterbi decoding method and viterbi decoding apparatus
Inventor: ISHIDA KATSUHITO
IPC: G11B20/18
Filed: 1993-12-21
Abstract: In a Viterbi decoding method or apparatus, a reception code, produced by precoding a transmission code and transmitting the precoded transmission code through a partial response transmission path, is processed to detect whether the present state is a plus (+) merge, a minus (-) merge or a no merge state.      A provisional value is estimated for the transmission code corresponding to the reception code, and the provisional value is stored in a buffer. When the present state is a (+) or (-) merge, that is, other than a no merge state, a decoded value is obtained for the transmission code and the provisional value in the buffer is updated with the decoded value.

Title: Process for vitrifying asbestos containing waste, infectious waste, toxic materials and radioactive waste
Inventor: LITOVITZ THEODORE A
IPC: B09B3/00
Filed: 1992-08-07
Abstract: Material, such as, for example, sealed double bags of as-bestos (24) containing waste or ash from infectious waste or toxic material or radioactive waste, is transferred into a glass melt of a furnace (10). Gas bubbles released into the melt form a gas curtain (12) which causes enhanced mixing of the materi-al to accelerate the dissolution of the components of the added material (7). The presence of the gas bubbles (12) reduces the cross section of the molten glass (32) through which current passes, which in tum increases the electrical resistance of the glass melt (32) or power density at constant current. A highly oxidizing hot region is produced under the location where the material is introduced into the furnace (10). Drawn off glass is shaped and quenched into at least two sizes of approximate spheres (23). The spheres (23) are cooled sufficiently fast to be thermally tempered and have a surface compressive strength le-vel above 5000 psi.

Title: Adaptive communication system for transmitting voice/data
Inventor: LINQUIST ROGER D
IPC: H04B7/185
Filed: 1993-06-02
Abstract: A data communication system is provided for generating information at a source (12) and transmitting it to a non-fixed subscriber transceiver unit (STU) (14). The information is first transmitted through a public telephone network (10) to a master station (13) when the master station (13) is operable to assemble a message containing the receiver identification number (RIN) and the source identification number (SIN) along with message information. This is broadcast to geographic stations that each have a defined RF  locale. Each of the geographic stations then transmits this message to the STU (14) along with specific information as to what type of RF links are available. Each of the geographic stations has a plurality of channels associated therewith that differ. The STU  (14) then transmits back to the geographic station in accordance with the parameters thereof. The geographic station then establishes a communication link with the STU (14) and requests data from the master station (13), which data is then transferred to the geographic station for buffering and subsequent transfer to the STU (14).

Patent CA-2121252-A1 (CA)
Inventor: SIIMAN OLAVI
IPC: H01F1/06
Filed: 1992-10-28
Abstract: ABSTRACT     A method is described for the preparation of uniform colloidal metal ferrite particles, for example MnFe2O4, at a relatively low temperature and in an aminodextran containing solution.  The aminodextran in solution acts as a vehicle for the nucleation and growth of colloidal particles of metal oxides while simultaneously preventing the aggregation of the newly formed particles by coating them to maintain their dispersion as separate single par-ticles.  Monodispersed metal ferrite particles have mag-netic properties that are useful for manufacturing transformers, inductors, and audio and video recording heads.  The aminodextran coated particles of the inven-tion also have utility as a substrate for carrying vari-ous biological molecules, for example antibodies, and for conducting immunoassays.

Patent CA-2140173-A1 (CA)
Inventor: KELLAM MARK D
IPC: H01L27/118
Filed: 1995-01-13
Abstract: Two prefabricated conductors (114 and 152) are connected with a via-like structure comprising a conducting strap (116) passing through a hole in a dielectric (115). Unlike the commonly used traditional via structures requiring that connecting holes be made before fabrication of the upper level of the conducting wires, the disclosed structure can be completed by making said hole and strap after both conductors are already fabricated. This delays connecting the wires in an integrated circuit until late in the fabrication process, thereby reducing the time and cost required to customize the interconnections in a prefabricated general-purpose mask-programmable circuit resembling a gate array. Several variants of the basic method are possible, differing in the exact configuration of the via-like structure and in the exact process used to fabricate the conducting strap.

Patent CA-2145404-A1 (CA)
Inventor: LANDRY JOHN A
IPC: G06F11/00
Filed: 1993-09-29
Abstract: A multiprocessor computer system includes fault tolerant power up logic for finding a functioning CPU to operate as logical CPUO.  Each microprocessor has a physical location designation which remains constant. When the system is powered up, all of the CPUs except the CPU in physical slot O (CPU PO) are initially placed in an inactive sleep state.  The microprocessor in physical location O performs its power on self test (POST), and if the CPU functions properly, the CPU is designated as logical CPUO (CPU LO).  The microprocessor then awakens the remaining CPUs and boots up the rest of the computer system.  If CPU PO is not functioning properly, after a given time period the system awakens the processor in the next physical location and repeats the process of testing the CPU. The process repeats until an operating microprocessor is found to perform the CPU LO functions.
