Abstract: A catalyzed polyurethane reactive hot melt adhesive is prepared from a reactive polyurethane prepolymer and 0.05 to 0.6% by weight of a 2,2'dimorpholinoethyl ether or di(2,6-dimethylmorpholinoethyl)ether catalyst. The adhesive is characterized by improved curing speed with little or no effect on the thermal stability. These reactive hot melts will bond to a variety of substrates including plastics, woods, fabrics and some metals making them ideal candidates for bonding dissimilar substrates. Moreover, they are flexible and durable by nature, so they may be used in extreme temperature ranges of -30 to +150°C while providing excellent moisture and chemical resistance.

Abstract: An improved heat-resistant surface contaminant containment boom is described, which has a floatation section incorporating refractory materials and spacing materials providing an air-gap around an inner float assembly which can be formed of less heat-resistant and more flexible materials. Further, the boom provides a water wicking action which draws water into the boom to be converted to steam. Provision is made for the steam to escape from the boom removing heat therefrom allowing the float assembly within to remain at a cooler temperature.

Title: Transgenic animals lacking proteolipid protein and method of making such animals
Inventor: STOFFEL WILHELM
IPC: C12N15/09
Filed: 1995-05-24
Abstract: Proteolipid protein and its isoprotein DM20, the two splice products of the PLP gene, are the two major membrane proteins of CNS myelin. For structural and functional analysis during myelination we replaced the PLP gene in mouse ES-cells by a mutated PLP targeting construct (deletion of 105 bp at the 3' end of exon III) with an antisense (as) oriented neo-gene in intron III, (plp-/dm20+/asneo). Brain RNAs of transgenic mice unexpectedly are devoid of PLP and DM20 mRNAs, PLP and DM20 isoproteins are completely missing in myelin. The plasma membrane processes of oligodendrocytes of the PLP-deficient mouse are spirally wrapped around axons of large diameter but have lost their compacted structure, smaller axons are non- or hypomyelinated. Young transgenic mice manifest no severe loss of CNS functions, although the conductance velocity is reduced by one half in PLP-deficient mice. These results define PLP as an essential membrane component responsible for the highly ordered myelin sheath ofCNS axons.

Title: Method and system for dynamic translation between different graphical user interface systems
Inventor: LONDON MITCHELL B
IPC: G06F9/44
Filed: 1995-06-16
Abstract: The present invention is directed towards a translation software that provides remote access to an application program that is executing on a host machine in its native operating system environment. The translation software monitors messages that are relayed from the application program to an application interface that is provided via the native operating system. Upon recognizing a message that affects a graphical user interface of the native operating system, the translation software converts the message into a protocol that is recognized by a remote graphical user interface. By monitoring and converting messages in this fashion, the translation software allows the application program to be displayed remotely.

Abstract: A cold plate (10) includes a recessed area (13) in its underside so that its inner tubes (12) will not migrate away from its top surface (14) during its casting process.  By restricting the movement of the tubes during the casting process, the cold plate has tubes located close to its top surface, thereby improving the heat transfer between fluids flowing through the tubes and ice placed over the cold plate to act as a heat sink As a result, the cold plate allows drinks to be dispensed that are colder and retain more carbonation.

Title: Procede et appareil permettant de simuler l'interference utilisateurs dans un systeme de communication a etalement du spectre
Inventor: SOLIMAN SAMIR S
IPC: H04B17/00
Filed: 1995-07-13
Abstract: Procédé et appareil permettant de simuler l'interférence de signaux dans un système de communication, tel que des systèmes de communication cellulaires ou sans fil. Ledit système de communication est de préférence d'un type dans lequel sont utilisés des signaux de communication à étalement du spectre et à accès multiple par différence de code (AMDC). Le procédé permettant de simuler une puissance d'interférence de signaux reçue par un récepteur de station de base consiste à estimer une première puissance (100, 110) de signal composite correspondant à la somme de la puissance des signaux transmis par une première série d'utilisateurs simulés situés dans la première cellule. Une estimation d'un premier débit de données normalisé (410) pour la transmission du signal composite est également effectuée. Un premier signal d'interférence est ensuite généré (114, 126, 128, 130) à un niveau de puissance déterminé sur la base de la première puissance de signal composite et du premier débit de données normalisé. Dans un mode de réalisation préféré, la première puissance de signal d'interférence est réglée selon une fluctuation de puissance moyenne (420) qui est une conséquence d'un asservissement de puissance (715). En outre, une seconde puissance de signal composite est déterminée par estimation de la somme de la puissance des signaux transmis par une seconde série d'utilisateurs simulés situés à l'extérieur de la première cellule. Une estimation similaire d'un second débit de données normalisé auquel cette puissance de signaux est transmise par la seconde série d'utilisateurs simulés est également effectuée. Cela permet de produire un second signal d'interférence sur la base de la seconde puissance de signal composite et du second débit de données normalisé. La production du premier signal d'interférence comprend typiquement la synthèse de bruit électrique (160) sur une bande de fréquence prédéterminée. La puissance du bruit électrique est ensuite réglée (170) selon le produit de la première puissance de signal composite et du premier débit de données normalisé. De plus, une séquence variable aléatoire peut être utilisée (400, 460, 530) pour modéliser des variations de la première puissance de signal composite.

Abstract: L'invention concerne un procédé et un appareil pour déterminer la teneur en analyte d'un échantillon en générant des premier et second signaux d'entrée et en dirigeant les signaux d'entrée sur l'échantillon. Les signaux d'entrée diffèrent en longueur d'onde par au moins 3 nanomètres. L'interaction entre les signaux d'entrée et l'échantillon génère des premier et second signaux de sortie. Chaque signal de sortie comprend un signal résonnant ayant un pic dont la longueur d'onde est sensiblement indépendante de la longueur d'onde du signal d'entrée respectif et un signal de sortie non résonnant ayant un pic dont la longueur d'onde dépend de la longueur d'onde du signal d'entrée respectif. On utilise un détecteur pour détecter les deux signaux de sortie et, en distinguant les signaux de sortie résonnants des signaux de sortie non résonnants, on obtient des données relatives à la teneur en analyte de l'échantillon. On peut appliquer aux signaux de sortie une analyse de régression des composants principaux ou une analyse quantitative multivariable, dans le but de distinguer entre les signaux résonnants et non résonnants. Le procédé et l'appareil décrits ici peuvent également distinguer les signaux de sortie résonnants entre eux, ainsi que les signaux de sortie non résonnants entre eux.
