Inventor: GILLIS DANIEL JOHN
IPC: C08F10/00
Filed: 1991-04-05
Abstract: Un procédé de polymérisation en solution et un catalyseur relatif à ce procédé, pour la préparation de polymères d'alpha-oléfines de poids moléculaire élevé, notamment des homopolymères d'éthylène et des copolymères d'éthylène et des C3-C12 alpha-oléphines. Le procédé s'effectue dans des conditions de polymérisation en solution à 105-320 °C. Le catalyseur est obtenu à partir de tétra-halogénures de titane, d'oxytrihalogénures de vanadium et de composés d'organoaluminium, dans lesquels un mélange des composantes de catalyseur subit un traitement thermique à 180-250 °C et est par la suite refroidi à une température de moins de 150 °C. De l'oxytrihalogénure de vanadium est alors ajouté. La solution de catalyseur produite est activée avec un composé d'aluminium. Le catalyseur fait preuve d'une bonne activité, présentant une activité supérieure à des catalyseurs auxquels l'oxytrihalogénure de vanadium n'est pas ajouté ou est ajouté à des températures supérieures à 150 °C.

Title: Rotating biological aquarium filter system.
Inventor: SNYDER WILFRED PHILIP
IPC: A01K63/04
Filed: 1991-06-10
Abstract: An aquarium filter system having a rotatably mounted filter body. The filter body is structured such that when mounted with a portion of the filter body submerged in moving water, rotational movement is imparted to the filter body by the moving water. As a result of the rotational movement, at least a portion of the filter body is alternately exposed to the water and the atmosphere. This fosters the growth of aerobic bacteria on the surface of the filter body. The aerobic bacteria reduces the level of toxins within the aquarium water.

Patent EP-0549793-A1 (EP)
Inventor: UEHARA TADAYOSHI
IPC: B21J9/12
Filed: 1991-07-18
Abstract: A method of plastic forming in which a blank in the die undergoes plastic deformation with the advance of a punch whose moving speed is controllable. Deformation of the die incurred by am impact caused when the punch strikes the die is prevented by slow advance of the punch until the die touches the blank. When the punch comes into contact with the die, the pressure to move the punch forward, while interfering with the advance of the punch, is raised to a limit at which plastic deformation occurs. The advance speed of the punch is controlled so that, with release of the pressure having interrupted the advance of the punch, distortion speed of the blank may be made substantially uniform almost throughout the area subjected to plastic forming. Uniform stress acting on the die as a result of uniformized distortion speed of the blank leads to a uniform amount of deformation of the die almost throughout area subjected to plastic forming, whereby lowering of precision in forming caused by fluctuations in the deformation amount of the die is prevented. With the pressure of ejecting means made relatively higher than that of the punch at the time of ejection, spring-back of the die is prevented by ejection of the blank under pressure.

Title: Systeme de securite pour vehicules
Inventor: GARLICK TREVOR STEWART
IPC: G01V3/08
Filed: 1991-08-28
Abstract: Système de sécurité pour véhicules comprenant une première et une seconde boucle conductrice (A et B) à monter sur un véhicule (C) en position pratiquement parallèle et avec un espace (D) entre elles. Chaque boucle est connectée à un premier amplificateur qui lui est associé (1, 2), et dont les sorties sont reliées à un amplificateur différentiel (3), conçu pour additionner les signaux de sortie en provenance des deux premiers amplificateurs. La sortie de l'amplificateur différentiel (3) est reliée à un détecteur à seuil (4), qui agit sur un verrou (5) et mémorise une condition d'alarme lorsqu'un champ magnétique mobile est détecté. Le signal de condition d'alarme fait l'objet d'une interrogation à distance, par exemple, au moyen d'un système de télécommande infrarouge (8, 11), qui déclenche une alarme (7). Tout champ magnétique mobile traversant l'espace entre les deux boucles (A et B) induit une tension dans chaque boucle. Les premiers amplificateurs (1, 2) détectent alors la tension induite, tandis que l'amplificateur différentiel (3) détermine le déphasage des deux tensions. Ce déphasage indique qu'un champ magnétique mobile a traversé l'espace entre les deux boucles (1 et 2), et signale la possibilité qu'un dispositif à bombe magnétique ait été fixé sur le véhicule.

Filed: 1991-10-21
Abstract: The invention relates to methods and mutation linkers to modify DNA, to methods for producing libraries containing a multiplicity of modified DNA, and to methods for using such libraries for screening modified proteins encoded by such DNA. The DNA targeted for modification typically encodes a polypeptide such as an enzyme. The libraries are used to determine the effect of such modification or the interaction of the modified polypeptides with a target. In preferred embodiments, the invention relates to methods for making and using libraries containing DNA encoding modified antibiotic hydrolases to screen antibiotics against one or more of the modified antibiotic hydrolases produced by such libraries. Susceptibility or lack of susceptibility of an antibiotic to neutralization provides an indication of whether wild-type antibiotic hydrolases are likely to mutate to confer resistance to the antibiotic.
