Patent EP-0406255-A1 (EP)
Inventor: MILLER GERALD A
IPC: G11C27/02
Filed: 1989-01-23
Abstract: L'amplificateur échantillonneur/bloqueur décrit comprend deux étages de transconductance (10, 12) dont les bornes d'entrée inversée sont connectées ensemble. En mode d'échantillonnage, le signal d'entrée est connecté à l'entrée non inversée du premier étage (10) et un condensateur de blocage (Cc) est connecté à la borne d'entrée non inversée du second étage (12) et est excité par la sortie de l'amplificateur via un circuit de réaction (28), lequel force la tension du condensateur de blocage à suivre le signal d'entrée. Lorsqu'on passe en mode de blocage, les rôles des deux étages de transconductance (10, 12) sont intervertis: la borne d'entrée non inversée du premier étage (10) est connectée via un circuit de réaction (36) à la sortie de l'amplificateur et le second étage (12) reçoit comme signal d'entrée la tension du condensateur de blocage, lequel se trouve alors déconnecté de la sortie de l'amplificateur. La tension décalée nette s'étant créée sur le condensateur de blocage représente la différence entre les décalages respectifs des deux étages de transconductance. Cette tension décalée nette est compensée par une tension égale et opposée en mode de blocage due à l'interversion des rôles des deux étages de transconductance (10, 12).

Abstract: A thermal cueing device is used to control a targetting system. The thermal cueing device has a thermal imager (2) and object identifying means (3) for identifying "hot spots" in the image produced thereby. A head-up display (5) displays, in association with a view of the scene represented by said image, a marker, including an identifying symbol, positioned so as to indicate the location of each object in the scene. A key pad (9) is provided to enable an operator to indicate the selection of an object according to its identifying symbol, and directing means (8, 12) direct the second thermal imager (14), of higher magnification, forming part of the targetting pad (13), according to the image coordinates for the selected object. The second thermal imager produces an enlarged image of the selected object, and permits a guidance system to lock on to this image.

Abstract: Process for preparing aryl esters of phosphonous acid of formula (V), where A is non-existent or a direct bond or a divalent hydrocarbon bridge with 1 to 6 carbon atoms, which can be substituted by the groups mentioned below, or a heteroatom, cycloalkylidene with 4 to 8 carbon atoms or phenylalkylidene with 7 to 12 carbon atoms, n is equal to 1 or 2, R<1> as a monovalent residue denotes certain non-aromatic or aromatic hydrocarbon residues, the aromatic residues denoting substituents such as alkyl, alkoxy, alkylthio, dialkylamino, aryl, aryloxy or halogen, and as a divalent residue denotes a phenylene or naththylene residue, which can carry non-aromatic hydrocarbon residues as substituents, R<2> is a non-aromatic hydrocarbon residue with 1 to 18 carbon atoms, aryl, arylmethyl, arylethyl or arylisopropyl, each aryl containing 6 to 10 carbon atoms, and R<3> denotes hydrogen or one of the groups mentioned under R<2>. In a first stage a halogenated hydrocarbon R<1>(-Hal)n, in which R<1> has the above-mentioned meaning, n = 1 or 2, and the halogen has an atomic weight of at least 35, is converted under Grignard conditions with at least molar quantities of magnesium to the corresponding organomagnesium compounds R<1>(MgHal)n. These are reacted in a second stage with phosphoric acid-bis-arylester halides of formula (VI), where R<2>, R<3> and Hal have the above-mentioned meanings, to form the phosphonous acid arylester (V). The invention also relates to a plastics moulding material, in particular a polyolefin moulding material, containing the phosphonous acid arylester of formula (V). The properties of the moulding material are superior to those of materials which contain phosphonites produced by prior art techniques.

Title: Method for implanting large volumes of cells on polymeric matrices.
Inventor: VACANTI JOSEPH P
IPC: C12N5/00
Filed: 1990-04-25
Abstract: The present invention is a method and means whereby large volumes of cells having a desired function are attached to, and, optionally, proliferated, on a biocompatible degradable, non-degradable or combination degradable-non-degradable scaffolding and transferred with mininal trauma and blood loss into a patient at a site appropriate for attachment, growth and function to produce a functional organ equivalent in the absence of vascularization of the implanted cell mass. In the preferred embodiment, multiple cell-matrix structures are implanted between folds of the mesentery. The method is particularly well suited for growth of endocrine structures, including liver, pancreas, and adrenal gland, as well as other tissues. The preferred material for forming the matrix or support structure is a biodegradable artificial polymer. Materials such as angiogenesis factors can be incorporated into degradable matrices for use in preparing the implantation sites prior to, or at the time of, implanting the cells. The function and viability of the attached cells can also be manipulated by treatment or coatiing of the matrix structure to increase the number of attachment sites.

Title: Purification of hydrogen peroxide.

Abstract: PCT No. PCT/GB90/01102 Sec. 371 Date Jan. 23, 1992 Sec. 102(e) Date Jan. 23, 1992 PCT Filed Jul. 18, 1990 PCT Pub. No. WO91/01267 PCT Pub. Date Feb. 7, 1991.The electronics industry demands that hydrogen peroxide for use therein be purified to very low levels of impurities, currently at the level of a few ppb for some impurities, or even lower. However, existing methods are either inherently unsafe because they bring concentrated hydrogen peroxide into contact with a concentrate of transition metal decomposition agents for peroxide and a purification resin which acts as a source of carbon, or are unable to attain the desired impurity level. In the instant purification process, the hydrogen peroxide solution is passed through a membrane having a very small pore size which contains an ion exchange resin that is capable of removing alkali and alkaline earth metal ions from solution. The feed solution in characterized in that it contains no more than a small proportion by weight of transition metals that catalyse hydrogen peroxide decomposition compared with the total metals content. The feed solution in some embodiments results from a prior treatment of an iron or copper contaminated solution with a dispersion of stannic oxide.
