Inventor: JACOBS JOCHEN DR
IPC: B01J2/22
Filed: 1987-12-19
Abstract: Free-flowing, particulate peracid concentrates which undergo no loss of activity on mixing with detergents or strong alkalis are prepared by compacting 50 to 95 % by weight of the organic peracid or of its salts with 5 to 50 % by weight of a water-soluble or water-dispersible salt or salt mixture which has a pH of 5 to 9.5 in 1 % strength aqueous solution, under elevated pressure and subsequently comminuting the compacted material to an average particle size of 0.1 to 2 mm. The pressure applied must not substantially exceed the limiting pressure at which no further compaction occurs, and should be, when a roller press is used, 0.2 to 0.7 t/cm of length of roller. Furthermore, the particle porosity measured by mercury porosimetry should be below 10 %.

Abstract: In the continuous manufacturing of metal strip from molten alloy, the nozzle (1) from which the melt issues to form the continuous strip by rapid-cooling solidification has an orifice that is discontinuous in the width direction of the strip; i.e., it is a multiple orifice(2). This enables amorphous and crystalline continuous metal strip to be produced in much greater widths than has hitherto been possible, and the strip thus produced is more uniform in thickness.

Abstract: An electrodeless fluorescent lighting device is disclosed comprising an outer bulb (22) coated internally with a fluorescent coating (20) which fluoresces when impinged by ultraviolet radiation generated in the bulb by an excitation means (12) which accelerates electrons within a toroidal chamber (14), filled with an ionizable gas which emits ultraviolet radiation under bombardment with electrons. The electrons are accelreated within the toroidal gas filled chamber by a coil (18) which generates an enclosed magnetic field, an induced electrical field, and a radiating electrical field, where the induced electrical field is substantially parallel and in the same direction as the magnetic field. Both the magnetic and induced electrical fields are applied at substantially the same frequency for accelerating and directing electrons for collision with gas composition atoms contained within a closed contour gas housing (14). An electrostatic shield (26) earthed at (28) is provided surrounding the excitation mechanism (12) to contain the radiating electrical field within the bulb (22). In a second embodiment, the toroidal gas chamber is omitted, and the ionizable gas is simply contained within the bulb (22). Ballast (30) provides an operating frequency in the range 0.1 to 50 Megahertz.

Abstract: La pression sanguine intraartérielle est mesurée de façon non invasive par un transducteur électromécanique (22) qui comprend un réseau d'éléments transducteurs (22-1 à 22-19). Le transducteur s'étend en travers d'une artère (24) avec des éléments transducteurs placés aux extrémités du réseau s'étendant au-delà des bords opposés de l'artère. Un ensemble de valeurs de pression diastolique et/ou systolique et d'amplitude d'impulsion est obtenu à partir des résultats de sortie des éléments transducteurs, valeurs qui sont stockées dans un ordinateur (62). Des informations concernant le patient, relatives au diamètre de l'artère sous-jacente et qui comprennent par exemple l'âge, le poids et le diamètre du bras et du poignet du patient, sont également introduites dans l'ordinateur (62) par l'intermédiaire d'un clavier (64), informations à partir desquelles est obtenue une estimation du diamètre de l'artère sous-jacente. En utilisant l'ensemble des valeurs d'amplitude des impulsions, on identifie un élément transducteur au centre d'une zone de recherche qui se trouve sensiblement au centre de l'artère. Un procédé par détermination du centre de gravité, par détermination de deux crêtes et/ou par ajustement de courbe peut être utilisé pour identifier l'élément transducteur au centre de la zone de recherche. Un groupe d'éléments transducteurs qui recouvre l'artère de diamètre estimé est ensuite identifié. En utilisant les résultats de sortie provenant uniquement dudit groupe d'éléments transducteurs, on identifie un élément transducteur ayant un minimum local de l'une des pressions diastolique et systolique, relatif au transducteur au centre de la zone de recherche, et c'est cet élément transducteur qui est choisi pour contrôler la pression sanguine.
