Patent EP-0222013-A1 (EP)
Title: Hydrocarbon sensor.
Inventor: LAHLOUH JOHN
IPC: G08B23/00
Filed: 1986-06-10
Abstract: An elongate sensor for detecting and locating presence of a liquid, e.g. water or a hydrocarbon. The sensor includes first and second elongate members which are spaced apart from each other and each of which is a metal conductor covered by a conductive polymer; a third, insulated elongate conductor; and an elongate insulating core. At least one of the elongate members is helically wrapped around the core. Presence of the liquid at any point along the length of the sensor causes the first and second members to be electrically connected at that point, creating a system in which the potential drop down one of the members can be measured and the location of the connection determined.

Title: Couteau de keratotomie radiale et systeme d'utilisation de celui-ci
Inventor: BERKMAN JOHN W
IPC: A61B17/32
Filed: 1986-08-22
Abstract: Un couteau de kératotomie radiale (10) comprend un transducteur de position linéaire précis (32) pour afficher numériquement l'extension d'une lame chirurgicale (16) au delà d'une partie de base (14) du couteau (10). Un système est également décrit pour remettre la lame en position zéro par rapport à la partie de base. Le système comprend un manchon de mise à zéro (60) ayant une membrane réfléchissante (61) qui réfléchit la lumière vers un détecteur (70). Le couteau (10) est introduit dans le manchon (60) de sorte que la partie de base (14) se trouve en contact avec la membrane (61) dans le système contenu dans une console (50). Lorsque la lame (16) avance pour entrer en contact avec la membrane réfléchissante (61) depuis l'intérieur du manchon (60), le motif de lumière réfléchie est modifié pour établir précisément une position zéro de la lame (16) du couteau par rapport à la partie de base (14). Le couteau (10) est ensuite retiré du manchon (60) et on fait avancer la lame (16) au moyen d'un micromètre (12) de sorte que le transducteur (32) produit un signal relatif au niveau de référence indiquant l'extension de la lame (16).

Abstract: A method and an apparatus suitably used with a visual recognition system or the like for measuring the shape of an object (6) by the optical cutting process is disclosed in which irregularities of the reflection characteristics on the object or under an environment subjected to variations in external light are removed for measurement. R light flux parallel to a slit beam providing an optical cutting beam is irradiated on the object by an optical system (3, 4). An original image not irradiated with any parallel illumination light is compared with an image obtained with a parallel beam irradiated to obtain reflection characteristics data on the object. This reflection characteristic data is used to correct an image formed at the time of irradiation of the optical cutting beam. When the optical cutting beam is irradiated, the existing image representing reflection characteristics is standardized with reference to the brightness of the optical cutting beam. The resulting data is used to correct the differential image obtained by subtraction between the image irradiated with the optical cutting beam and the original image. The reflection irregularties are thus removed for an improved measurement accuracy.

Abstract: De la subtilisine mutée appropriée à être mélangée à des compositions de lavage et présentant une stabilité bien plus grande par rapport à des sérine protéases du Bacillus d'origine naturelle est préparée en exprimant un gène modifié codant la subtilisine dans le Bacillus subtilis. Un produit analogue de subtilisine préféré diffère des protéases alcalines de Bacillus de type sauvage par le fait d'avoir un acide aminé quelconque, et de préférence la sérine, en position 218 au lieu de l'asparagine. Le produit est obtenu de préférence dans une souche de B. subtilis qui est muté pour bloquer la synthèse de protéases endogènes. Le procédé de remplacement d'un Asn ou un Gly dans une séquence Asn-Gly de manière à améliorer la stabilité thermique au pH peut être appliqué à d'autres sites dans la subtilisine et à d'autres protéines également.

The multiple equipping head (1) executes a collecting event via delivery units (4) whereby it picks up components. The equipping of the printed circuit board (5) from the equipping head occurs in a second procedure, whereby the multiple equipping head (1) need not move back and forth between delivery unit (4) and printed circuit board (5) after every placement of a component (3) onto the printed circuit board (5). The components that were picked up by the suction pipettes (2) are processed by processing stations (8) after the collecting and before the equipping. Here, the components are centered, contacted, measured and tested.

Abstract: A process for activating metal hydride former particles used in suspension in an inert liquid for the absorption of hydrogen includes the steps of
     a) heating in a reactor a suspension of dried metal hydride former particles in a degassed inert liquid to elevate the temperatures,   b) evacuating the reactor,   c) introducing hydrogen into the reactor until a pressure above the hydrogen partial pressure has been achieved,   d) slowly releasing the pressure and   e) evacuating the reactor at elevated temperatures.   
     This activation process avoids the activation in the gaseous phase which hitherto in combination with the activation in the liquid phase had be to carried out.
