Patent MX-9504244-A (MX)
Title: Spread-response precoding system for wireless transmission.
Inventor: WORNELL GREGORY W
IPC: H04L1/00
Filed: 1995-10-06
Abstract: Method and apparatus for preparing a message stream of symbols for wireless transmission by pre-coding in through convolution with a characteristic "signature" of predetermined symbols identifying a particular user of the message system. The time duration of the signature should exceed the inter-symbol interval of the message stream in order to reduce the likelihood of error caused by fading in the transmission channel.

Title: Use of phosphonylmethoxyalkyl nucleosides for the treatment of raised intraocular pressure.
Inventor: FREEMAN WILLIAM R
Filed: 1995-03-31
Abstract: Methods for treatment of conditions of abnormally increased intraocular pressure, particularly those caused by glaucoma, by administration of phosphonylmethoxyalkyl nucleoside analogs are provided. Compositions formulated and packaged for intraocular administration for use in the methods are also provided. Administration of the compound may be by intravitreal injection, aqueous humor injection, injection into the external layers of the eye, such as subconjunctival injection or subtenon injection, or may be, when penetrating derivatives are used, by topical application to the eye. The degree of reduction in pressure is dosage-dependent, and significant reduction in pressure is obtained. A single injection can produce prolonged, and perhaps permanent, lowering of the intraocular pressure.

Title: Enhanced carotenoid accumulation in storage organs of genetically engineered plants.
Inventor: HAUPTMANN RANDAL
IPC: A01H5/00
Filed: 1995-10-27
Abstract: A transgenic higher plant, seed containing the transgene, and methods of providing enhanced carotenoid accumulation are disclosed. The transgenic higher plant has a genomic structural gene that encodes a chimeric polypeptide conjugate and over accumulates a colored native carotenoid in a preselected storage organ relative to the accumulation in a non-transgenic plant of the same type. Expression of the chimeric polypeptide is driven by a promoter operatively linked to that structural gene that provides storage organ-enhanced expression. The chimeric polypeptide has an N-terminal plastid transit peptide portion whose C-terminus is linked to the N-terminus of a non-higher plant phytoene synthase enzyme.

Title: Shock absorber for a drill string
IPC: E21B17/07
Filed: 1970-05-25
Abstract: Shock absorber for a drill string This is particularly used to protect the drill bit at the string's lower end, where a tubular housing is fitted. A tubular mandrel slides in the latter, which is suspended, to drive and rotate with it. The mandrel is connected to the bit and carries a pair of spaced seals to pack between it and the housing, where it makes a closed chamber. This chamber has non-compressible cushioning fluid and a check valve to prevent fluid flowing up above it. This resists the housing's downward reciprocation over the mandrel.

Title: Treatment of boreholes with chemical reagents - injected by high pressure gas produced on site by vaporising liquefied gas
IPC: E21B43/25
Filed: 1975-01-10
Abstract: Treatment of wells by (a) heating a stream of pressurised liquefied gas to evaporate this and give an inert gas under high pressure, (b) gasifying a liquid reagent with a high pressure inert gas prepared at the well site (c) transporting the gasified reagent into the well under pressure in order to contact desired parts of the borehole as well as the rocks which this transverses and (d) the lowering of the pressure in order to recover the used gasified reagent from the well. The use of an inert gas eliminates fire or explosion rist as well as preventing or retarding corrosion and the use of a liquefied gas as a source of high pressure gas eliminates the need for costly and heavy high pressure air compressors. The preferred inert gas is nitrogen and the reagent may be an acid, a solvent, a cleaning medium, a break-forming fluid or corrosion retarder. Other liquefied gases e.g. CO2, natural gas air can be used in specific cases.
