Title: New and useful improvements in fiber-reinforced composite materials structures and methods of making the same
Inventor: BURGESS KEITH E
IPC: B32B5/00
Filed: 1999-06-28
Abstract: Reinforcement preforms and methods for making same for use in fiber-reinforced composite materials structures are disclosed, in which the reinforcement preforms comprise first and second reinforcement preform elements which include strength reinforcement fibers that are in desired directional orientation.      The first element has a cross-fiber surface which extends transverse of its constituent strength reinforcement fibers and is in contacting juxtaposition to a selected surface region of the second element, forming an abutment therebetween. Abutment strength reinforcing fibers, which may optionally be introduced in situ by a continuum of fibers, such as a yarn or thread, extend through at least a portion of said second element and its said selected surface region, the abutment, said cross-fiber edge surface, and into the first element substantially in the direction of orientation to its constituent strength fibers to which its cross-fiber surface is transverse.

Title: Method for preparing adenovirus vectors, vectors so prepared, and uses thereof
Inventor: SHENK THOMAS
IPC: A61K35/76
Filed: 1998-11-25
Abstract: Multiple binding sites for the transcription factors MAZ and Sp1 within the adenovirus type 5 major late promoter have been identified by DNase I  protection studies. In the proximal region of the promoter, both MAZ and Sp1 interact with GC-rich sequences flanking the TATA box. Two MAZ binding sites are centered at -18 and -36 relative to the transcriptional initiation site.  Sp1 bound only to the -18 GC-rich sequence. Several sites of interaction were also evident in the distal region of the promoter. Both MAZ and Sp1 interacted with a sequence centered at -166, and MAZ bound weakly to an additional site centered at -130. Over expression of MAZ or Sp1 activated expression from the major late promoter in transient expression assays. Mutational analysis of the GC-rich sequences in the major late promoter suggested that a primary target of MAZ activation is the GC rich sequences flanking the TATA sequence, whereas Sp1 requires the distal GC-rich sequence elements to stimulate gene expression. This activation is enhanced by the adenovirus E1A protein, and evidence for interaction between E1A and both transcription factors was obtained using an immunoprecipitation assay. Activation by MAZ and Sp1 also was observed in transfection studies using the complete adenovirus type 5 genome as the target. Increased levels of late mRNA from both the L1 and L5 regions were observed when MAZ or Sp1 expression plasmids were transfected with viral DNA. Unexpectedly, activation of the major late promoter by MAZ and Sp1 was detected irrespective of whether the viral DNA could replicate.

Title: Selective technique for rapid identification of proteins and genes and uses thereof
Inventor: BRUKNER IVAN
IPC: C12Q1/68
Filed: 1998-12-01
Abstract: The current invention relates to a method for selecting oligonucleotides able of identifying differences at the molecular level between a plurality of biological systems. This method has been named "STRIPGEN" for "<u>S</u>elective <u>T</u>echnique for <u>R</u>apid <u>I</u>dentification of <u>P</u>roteins and <u>GEN</u>es". The STRIPGEN method involves selection of oligonucleotides having a higher affinity and specificity for target molecules of a first biological system and a lower affinity for binding target molecules of a second biological system. STRIPGEN is based on a scheme of positive selection over a first biological system and negative selection over a second biological system, and uses step-wise iterations of binding, separation and amplification. This method is very poweful since it can discriminate very subtle differences between biological systems of the same type such as between normal and abnormal cell types.

Title: Scaling multi-dimensional signals using variable weighting factors
Inventor: MARTIN RUSSEL A
IPC: G06T3/40
Filed: 1999-04-23
Abstract: An image or other multi-dimensional data set may have its sampling rate changed by determining weighting factors for the values of points in the original (input) data set used to calculate the value of a point in the new (output) data set. The weighting factors are determined using a function, such as a Gaussian function, that takes as input the relative location of the point in the new data set with respect to the locations of surrounding (neighboring) points in the original data set. The values of the points in the original data set are multiplied by the weighting factors, and the resultant products are added (or combined by another function) to give a value of the point in the new data set. In particular, when the input and output data sets are regularly spaced, such as with pixels for computer displays, the locations of the surrounding points and thus their weights repeat periodically. This results in increased efficiency because the surrounding points and their weights need to be determined only for a subset of the output data set.

Title: Improvements in or relating to digital communications apparatus
Inventor: JUDGE RUPINDER
IPC: H04W88/02
Filed: 2000-10-03
Abstract: Speech recording is effected in a GSM phone handset (100) by storing in a memory (116) speech frames during the presence of speech, one or more SID  frames during the absence of speech, and data representative of the duration of the absence of speech. In this way memory (116) does not store silent speech frames, and utilisation of memory space is therefore particularly efficient. In addition, items such as a voice activity detector and a comfort noise estimator, which are already provided in the handset as part of the GSM system, are "re-used" by the invention, thereby making efficient use of already-provided hardware/software.

Abstract: A method and apparatus for conducting business via the worldwide Web in which business programming is isolated from Web user interface programming. In accordance with the invention, a gateway servlet interfaces between a consumer's browser's software and a e-business retailer's back-end business software running, for instance, on a separate mainframe. The gateway servlet receives input information from the consumer and forwards it to the back-end software for business processing. The back-end software returns a user interface record object to the gateway which then instantiates a Java bean and invokes a Java Server Page in order to generate a HTML page to be returned to the user based on the user input information and the business back-end processing thereof.

Title: Peroxide, oxygen, and peroxide/oxygen brightening of chemical and mixed waste pulps
Inventor: EVANS TIMOTHY D
IPC: D21C9/10
Filed: 1998-05-15
Abstract: A composition and method for use in the peroxide, oxygen, or peroxide/oxygen stage of brightening pulps with less than 18 % lignin utilize a megnesium compound in a sodium silicate solution to form a higher percentage of high molecular weight silicates. Such high molecular weight silicates preferentially adsorb transition metal impurities which, if left in solution, would tend to decompose hydrogen peroxide and organic peroxides. Hydrogen peroxide is added to peroxide and peroxide/oxygen stages, while it is generated, along with organic peroxides, during an oxygen stage. Decomposition decreases the amount of peroxide that actually reacts with lignin and generates free radicals that attack the desired product, carbohydrate fibers. The high molecular weight silicates can be formed by using any magnesium compound which dissociates to form Mg(OH)+ cations, which in turn cause a silicate polymerization reaction. The formation of Mg(OH)+ cations from magnesium compounds occurs most realidy over a pH range of at least about 8 and preferably between about 8 and about 12. The magnesium compound is added in an amount to achieve an Mg:SiO2 mass ratio of between about 1:46 to about 1:2, and preferably between about 1:15 to about 1:3.
