Filed: 1997-11-19
Abstract: The disclosure relates to a method of monitoring a communications network comprising a plurality of node equipment, eg switches, and link equipment, eg fibre optic links, in which performance parameters of individual components of the node equipment are used to determine an overall performance parameter for the node equipment. By comparing like performance parameters for individual network elements, the performance of different types of network element can be compared with each other. Parameters which can be monitored include quality of service, cell discard, cell loss, and other measures of network performance. Each of a plurality of monitoring sessions runs contemporaneously, each monitoring a respective set of operational parameters. During each monitoring session, there are input a set of operational parameters (132) to be monitored. Data relating to the operational parameters is collected from one or more network elements, and a display of the data is produced (134).

Filed: 1996-03-25
Abstract: Associative thickeners of the present invention are water-soluble polymer compositions that have a backbone of poly(acetal- or ketal-polyether) with ends that are capped with hydrophobic groups. They are prepared by copolymerizing an alpha, omega-diol, -dithiol or -diamino polyether with a gem-dihalide compound in the presence of a base to form an alpha, omega-diol, -dithiol or -diamino poly(acetal-or ketal-polyether) which in turn is reacted with hydrophobic reagents to form the final product. These associative thickeners are used in film-forming coating compositions, such as latex paints.

Abstract: An advanced low cost adaptive frame grabber has been described. Main area of application for this framegrabber is in fingerprint identification, verification systems, but it could successfully be used in other biometric identification systems, such as facial, iris or eye identification and/or verification systems. The proposed framegrabber is also very suitable for all applications in other areas, like medical electronics, car electronics etc., where automatic image enhancement and/or transformation from grey scale to line art is required.   The adaptive framegrabber automatically estimates the dynamic range of the acquired image ant sets up a proper offset and measurement range for the video analog to digital converter (ADC). It could also be operated in two different modes, in one the image is acquired as a full grey scale image, and in the other - as a line art ( black and white ) image.     Full controls over the image size and resolution are provided.

L'outil de coupe comporte une pièce de coupe insérée, ayant une extrémité portant un revêtement de diamants et fixée par brasage à la pièce insérée. On forme l'outil de coupe en fixant par brasage la pièce à un corps d'outil avec un alliage de brasage, cette opération consistant à chauffer la pièce et le corps de l'outil à une température suffisante pour faire fondre l'alliage de brasage. La pièce insérée et le corps de l'outil sont ensuite refroidis et trempés pour solidifier l'alliage de brasage et provoquer une transformation martensitique. Finalement, l'extrémité améliorée par des diamants est brasée sur la pièce insérée pendant que la température du corps de l'outil est maintenue en dessous de la température à laquelle le corps de l'outil commencerait à se ramollir. Selon ce procédé, l'outil de coupe est formé sans zone de revenu présentant une dureté moindre.

Filed: 1997-03-24
Abstract: A method and apparatus for an in-home communication system based on the use of a telecommunications terminal (110) of a Fiber-to-the-Curb (FTTC) network is described. In this system signals are sent from a first device (140) in a home (250) to the FTTC terminal (110) over a subscriber coaxial cable network, and routed from the telecommunications terminal (110) back to the home (250), whereby they are received by a second device (140) in the same home (250).

Title: Liposomal antineoplaston therapies with markedly improved antineoplastic activity
Inventor: BURZYNSKI STANISLAW R
IPC: A61P25/00
Filed: 1997-05-14
Abstract: A second generation of antineoplaston therapies with markedly improved antineoplastic activity is disclosed. Among others, members of the antineoplaston family include phenylacetate (PN), 3-phenylacetyl-amino-2,6, piperidinedione (CN), and hydrolysis derivatives of CN: phenylacetylglutamine (PG) and iso-phenylacetylglutamine (Iso-PG). In part, these increases in antineoplastic activity result from large increases in the transport of antineoplaston compositions into cells. Importantly and unexpectedly these increases in antineoplastic activity also result from the capacity of the drug delivery system to direct antineoplaston compounds intracellular trafficking to intracellular binding sites influencing cell viability and proliferation. Liposomal formulations of antineoplaston compositions increase in vitro antineoplastic activity by a factor of 750 to 1500 as compared to administration of antineoplaston compounds given without liposomal formulations. In addition, these liposomal formulations enhanced cellular uptake of antineoplaston compounds form 30 to more that 80 fold. Liposomal formulations were also found to increase intracellular levels of the antineoplaston CN(3-phenylacetyl-amino-2,6, piperidinedione) by directing CN to intracellular binding sites that influence cell viability and proliferation and block its hydrolysis. Under conditions where free CN has no antineoplastic activity, liposomally formulated CN can produce essentially complete and relatively long-lasting blockade of cell growth. Cell growth was found to be restored as intracellular levels of bound CN decrease to undetectable levels.
