Title: Promoter for transgenic plants
Inventor: ROGERS STEPHEN GARY
IPC: C12N15/29
Filed: 1990-10-30
Granted: 1995-10-24
Abstract: PROMOTER FOR TRANSGENIC PLANTS         A  full-length  transcript  promoter  from figwort mosaic virus (FMV) is identified and its DNA sequence given.   The promoter functions as a strong and uniform promoter for chimeric genes inserted into plant  cells.   This  strong  promoter  function  is exhibited by a histochemical assay in floral buds and by reproductive scores of transgenic plants including the  promoter.   The  promoter  preferably  includes  a 5' leader sequence that may be from the FMV itself or from  a  heterologous  source with  respect  to  the promoter.   The promoter is used in a plant cassette vector,   a   chimeric  gene   and  in  methods   for transforming plant cells to obtain transgenic plants, plant cells or seeds incorporating the FMV promoter.

Abstract: The steel strip is passed through a zinc bath with an aluminium content of approximately 55% by weight and a silicon content of 1% to 2% by weight, to which is added strontium in a quantity equal to 0.2% maximum by weight and at least one other element selected from among vanadium and chromium, each in a quantity equal to 0.2% maximum by weight. The addition of strontium and chromium and/or vanadium stabilises the structure of the coating and reduces the formation of acicular precipitates of silicon. The coating has an improved adherence and ductility which permits it to be formed without cracking, while retaining an excellent resistance to corrosion. The resulting crystallisation pattern of the coating is also finer and more regular and is independent of the substrate.

Title: Method for reducing the risk of poor reception in a mobile telephony system
Inventor: KAELLANDER STEFAN ERIK PAULUS
IPC: H04B14/00
Filed: 1991-09-18
Granted: 1999-11-16
Abstract: A method of reducing in a digital time multiplex mobile telephony system the risk of poor reception as a result of the occurrence of points of low signal strength, so-called zero points. Transmission from fixed stations is effected with a polarization direction which is changed stepwise between different parts of the transmitted information. This causes the fading patterns around receiving stations to change in time, and also causes any zero points to be moved in the geography, therewith making it improbable that more than a small part of an information frame will be lost. In the case of a GSM-type system, the polarization direction is changed for each. new TDMA-frame.

Title: Method and system for natural language translation
Inventor: BROWN PETER F
IPC: G06F17/27
Filed: 1992-05-15
Granted: 1998-12-22
Abstract: The present invention is a system for translating text  from a  first  source  language  into  second target language. The system assigns probabilities or scores to various target-language translations and then displays or makes   otherwise   available   the   highest,   scoring translations.  The source text is first transduced into one or more intermediate structural representations. From these   intermediate   source   structures   a   set   of intermediate target-structure  hypotheses  is  generated. These hypotheses are scored by two different models:  a language model which assigns a probability or score to an intermediate target structure,  and a translation model which assigns a probability or score to the event that an intermediate  target  structure  is  translated  into  an intermediate   source   structure.    Scores   from   the translation model and language model are combined into a combined  score  for  each  intermediate  target-structure hypothesis.  Finally, a set of target-text hypotheses is produced   by    transducing    the    highest    scoring target-structure hypotheses into portions of text into the target language.   The  system can either run into batch mode, in which case it translates source-language text into a target language without human assistance, or it can function as an aid to  a human translator.  When functioning as an aid to a human translator,  the human may simply select from the various translation hypotheses provided by the  system,  or he may optionally provide hints or constraints on how to perform one or more of the states of source transduction, hypothesis generation and target transduction.

Title: Method of packaging a beverage
Inventor: LYNCH FRANCIS JOSEPH
IPC: B67C3/00
Filed: 1992-06-23
Granted: 2002-06-11
Abstract: A method of packaging a beverage having gas in solution has an open topped container 1 in which is located a hollow insert 5 having a restricted aperture 12. The container is charged with the beverage such as beer 15 so that the aperture 12 is submerged in the beverage and the container is sealed to form a headspace 19 which is pressurised, preferably by dosing with liquid nitrogen.     Following sealing the container is rapidly inverted to locate the aperture 12 in the headspace 19 so that gas pressures in the insert chamber 10 and the headspace 19 come into equilibrium. With the fluid contents in equilibrium, or substantially so, the package is reinvented so that gas under pressure in the insert chamber 10 communicates directly by way of the aperture 12 with beer in the chamber 10. Upon opening of the headspace 19 to atmospheric pressure for dispensing the beer a pressure differential is developed by which gas from the insert chamber 10 is initially ejected through the aperture 12 into the beer 15 to effect in the development of a froth on the beer 15. Beer 30 which may flow into the insert chamber 10 prior to the aperture 12 moving to communication with the headspace 19 is accommodated within a well 13 of the insert chamber 10 remote from the aperture 12 to alleviate the ejection of such beer 30 into the beer 15.
