Patent EP-0190315-A1 (EP)
Title: Dehydrated liposomes.
Inventor: JANOFF ANDREW S
IPC: A61K31/7042
Filed: 1985-08-07
Abstract: Dehydrated liposomes are prepared by drying liposome preparations under reduced pressure in the presence of one or more protective sugars, e.g., the disaccharides trehalose and sucrose. Preferably, the protective sugars are present at both the inside and outside surfaces of the liposome membranes. Freezing of the liposome preparation prior to dehydration is optional. Alternatively, the protective sugar can be omitted if : (1) the liposomes are of the type which have multiple lipid layers ; (2) the dehydration is done without prior freezing ; (3) the dehydration is performed to an end point which results in sufficient water being left in the preparation (e.g., at least 12 moles water/mole liped) so that the integrity of a substantial portion of the multiple lipid layers is retained upon rehydration. Concentration gradients capable of generating transmembrane potentials can be created across the liposome membranes either before or after dehydration, and the transmembrane potentials resulting from these gradients can be used to load charged materials, e.g., drugs, into the liposomes.

Abstract: Les performances d'un système d'avertissement de la proximité du sol peuvent être améliorées, surtout dans des cas où les performances de l'avion lui-même ont été dégradées par un facteur tel que le cisaillement du vent, en étendant les enveloppes d'avertissement en Mode 1 (24) et Mode 3 (32) jusqu'à cinq pieds du sol. D'autres améliorations des performances d'avertissement peuvent être obtenues en contrôlant l'angle de trajectoire de vol (46) lorsque l'avion se trouve près du sol. Les avertissements sont fondés sur un réseau logique (28) qui utilise l'altitude radio (12), la vitesse barométrique d'altitude (14), la vitesse (50) de l'avion, la marge de décrochage (82), et une source (10) de signaux représentant l'angle d'attaque, l'accélération verticale, et la phase de vol de l'avion. Un avertissement (30) est ainsi donné pour faire tanguer l'avion sauf lorsque la marge de décrochage est inférieure à une valeur prédéterminée.

Abstract: The present invention is equipped with a plurality of print buffers (27, 28) for inputting print data into a thermal head (10), wherein such print data are selectively fed to simply change the current on-time for energizing the heating elements (35) of the thermal head relative to specific information (17) out of the entire information to be printed, so that the specific information (17) is printed emphatically in a particular colour to become consipicuous, and simultaneously the contour of each specific character is edged in a basic colour to be distinctly legible. Such edged print is attained by utilizing the gradient of the temperature distribution induced in the heating elements by the current on-time control system, hence eliminating the necessity of any edging print data to consequently simplify the control.

Abstract: A photoelectric converting device comprises a plurality of photoelectric converting cells. Each cells has a semiconductor transistor consisting of two main electrode regions (12) (4) formed of a semiconductor of one conductivity type and a control electrode region (10) formed of a semiconductor of the opposite conductivity type, and a capacitor (11) (13) (10) for controlling a potential of the control electrode region in a floating state. 
     Each of the photoelectric converting cells performs at least the operations to accumulate carriers generated due to an incident light into the control electrode region and read out an accumulated voltage generated due to the accumulated carriers by controlling the potential of the control electrode region in the floating state through the capacitor. 
     An insolating region for electrically isolating the adjacent photoelectric converting cells is constituted by an insulating region (8) formed on the basis of a concave portion formed due to an etching and a semiconductor region (7) having a high concentration formed under the insulating region. 
     The high concentration semiconductor region consists of a semiconductor of the same conductivity type as that of the main electrode regions of the photoelectric converting cells.

Abstract: This method for immunological determination of amines in biological media consists of: (a) reacting a quinone (in particular, p-benzoquinone) with the amine (for example histamine) present in the test sample; (b) introducing into the medium a monoclonal antibody which specifically recognizes the amine-quinone reaction product formed; and (c) determining one of the forms of the monoclonal antibody present. When the quinone is used in the immobilized state, the monoclonal antibody present is determined in its complexed form with the amine-quinone reaction product (direct type method); when the quinone is used in the free state, the monoclonal antibody is determined in its free form (enzymoimmunometric method or competitive immunoenzymatic method).

Title: Appareil pour decharger en vrac une matiere thermoplastique solidifiee de seaux et de tambours

Abstract: Appareil pour décharger une matière fondant à chaud (65) d'un contenant (19) comprenant un assemblage à plateau mobile verticalement ayant un plateau (21) supporté par un chariot à plateau (35). Le poids de l'assemblage de plateau est emprisonné entre un ressort d'équilibrage (45) qui sollicite l'assemblage de plateau vers le haut et un ressort de pression (49) qui exerce une pression vers le bas sur l'assemblage de plateau. Les ressorts sont fixés autour d'une vis-mère motorisée (53) retenant par dessous le ressort d'équilibrage (45) contre l'assemblage de plateau et un écrou (51) d'ajustement de la pression retenant par en-dessus le ressort de pression contre l'assemblage de plateau. La descente de la vis-mère (53) sans un mouvement équivalent de l'assemblage de plateau provoque un déséquilibre des tensions des ressorts car le ressort d'équilibrage (45) se dilate et le ressort de pression (49) se comprime. Un contacteur de fin de course (59) restreint le déplacement que peut effectuer la vis-mère (53) après contact du plateau avec le matériau fondant à chaud (65) et empêche le chariot à plateau de se déplacer davantage. Au fur et à mesure que de la matière sort, le chariot à plateau (35) rattrape lentement la position de la vis (53), et finalement le contacteur de fin de course (59) entrera une fois encore en action permettant à la vis (53) de descendre d'une quantité supplémentaire présélectionnée déterminée par le contacteur de fin de course (59). L'appareil contient également un commutateur de sécurité (69) d'une tête d'application, lequel est activé pendant des périodes prolongées de non utilisation. Lorsqu'il est activé, le commutateur de sécurité (69) empêche le mouvement de la vis (53).
