Patent MX-PA05006522-A (MX)
Title: Product quality enhancement in mammalian cell culture processes for protein production.
Inventor: GANGLOFF SCOTT
IPC: C12P21/00
Filed: 2003-12-18
Abstract: The present invention describes methods and processes for the production of proteins, particularly glycoproteins, by animal cell or mammalian cell culture, illustratively, but not limited to, fed-batch cell cultures. The methods comprise feeding the cells with D-galactose, preferably with feed medium containing D-galactose, preferably daily, to sustain a sialylation effective level of D-galactose in the culture for its duration, thus increasing sialylation of the produced proteins. The methods can also comprise at least two temperature shifts performed during the culturing period, in which the temperature is lower at the end of the culturing period than at the time of initial cell culture. The cell culture processes of the invention involving two or more temperature shifts sustain a high cell viability, and can allow for an extended protein production phase. The methods can also comprise the delayed addition of polyanionic compound at a time after innoculation. Supplementation of the cultures with D-galactose, preferably in a feed medium, to sustain galactose at sialylation effective levels in the cultures until the end of a culture run reverses a decline in sialylation that accompanies culture scale up, and is advantageous for large scale culturing processes.

Title: Attachment means for a cosmetic dispenser.
Inventor: SOMERS MARK GEOFFREY
IPC: A45D34/04
Filed: 2005-07-20
Abstract: An improved dispenser secures the cap (2) to the bottle(5), and especially to the housing, by a plurality of sets of mounting elements(10, 41), one (10) of which comprises a cam (12) providing axial movement of the cap (2) when it is rotated around the bottle (5) and the other (41) a follower (43), such a lug and bayonet.

Title: Components and methods for processing wireless communication data in presence of format uncertainty.
Inventor: EDWARD L HEPLER
IPC: H04W56/00
Filed: 2004-02-18
Abstract: Components and method are provided to efficiently process wireless communications data where prior knowledge of the specific format of the communication data is not available. A wireless transmit receive unit (WTRU) is configured for use in a wireless communication system where communication data for selected channels is transmitted in system time frames in formats selected from among a set of predefined formats. The WTRU has a receiver, a memory, a received chip rate processor (RCRP), a format detector and a de-interleaver. The RCRP is preferably configured to despread each wireless signal of spread data received in each time frame using a minimum spreading code or other appropriate key sequence and to store resultant despread data for each respective time frame in the memory. The format detector is preferably configured to determine the number of physical channels and the respective spreading factor for each physical channel for the wireless signal of spread data received in each time frame. The de-interleaver is preferably configured to de-interleave the stored data despread by the RCRP for each respective time frame into the number of physical channels determined by the format detector for the respective time frame.

Title: Improved transmitter for encoded data bits
Inventor: DENT PAUL W
IPC: H04L1/00
Filed: 1997-05-20
Abstract: QUADRATURE AMPLITUDE MODULATED SIGNALS ARE GENERATED FROM DATA BITS BY USING A FIRST QUADRATURE PHASE SHIFT KEYING (QPSK) MODULATOR FOR ENCODING A FIRST PAIR OF THE DATA BITS INTO ONE OF FOUR CARRIER SIGNAL PHASES, THEREBY PRODUCING A FIRST QPSK SIGNAL. A SECOND QPSK MODULATOR ENCODES A SECOND PAIR OF THE DATA BITS INTO ONE OF FOUR CARRIER SIGNAL PHASES, THEREBY PRODUCING A SECOND QPSK SIGNAL. THE FIRST QPSK SIGNAL IS AMPLIFIED TO A FIRST POWER LEVEL, AND THE SECOND QPSK SIGNAL IS AMPLIFIED TO A SECOND POWER LEVEL. THE FIRST AND SECOND AMPLIFIED SIGNALS ARE THEN COMBINED TO PRODUCE A SIGNAL IN WHICH FOUR DATA BITS ARE ENCODED. IN ANOTHER ASPECT OF THE INVENTION, A NEW TYPE OF MODULATION, CALLED OFFSET QUADRATURE PHASE SHIFT KEYING (OQPSK), IS USED IN PLACE OF THE FIRST AND SECOND QPSK MODULATORS, SO THAT AN OFFSET QUADRATURE AMPLITUDE MODULATION (OQAM) TRANSMITTER IS FORMED. AN OQPSK MODULATOR ENCODES DATA BITS BY ENCODING A FIRST SUB-GROUP OF THE DATA BITS INTO A REAL PART OF A COMPLEX SIGNAL AT AN ODD INSTANT OF A CLOCK, AND BY ENCODING A SECOND SUB-GROUP OF THE DATA BITS INTO AN IMAGINARY PART OF THE COMPLEX SIGNAL AT AN EVEN INSTANT OF THE CLOCK. OQPSK MODULATION PROVIDES THE BENEFIT OF HAVING ALL SIGNAL TRANSITIONS BEING CONSTRAINED TO TRAJECTORIES AROUND CONSTANT RADIUS CIRCLES, THEREBY PRODUCING SPECTRAL EFFICIENCY.
