Abstract: A developing method and an apparatus including forming a layer of electrically charged toner particles (28) on a surface of the developer carrying member and dispersing magnetic particles (27) retaining on their surfaces electrically charged toner particles on the surface of the developer carrying member, carrying the particles on the developer carrying member to a developing position where a surface of an electrostatic latent image bearing member for bearing an electrostatic latent image is opposed with a clearance to the surface of the developer carrying member, applying an alternating electric field across the clearance and forming the magnetic particles into chains of the magnetic particles by magnetic field generating means disposed behind the developer carrying member, and developing the electrostatic latent image by the charged toner particles on the surface of the developer carrying member and on the surfaces of the magnetic particles.
Patent EP-0347128-A1 (EP)
Inventor: HOEL ELVIN LYNN
IPC: C08F4/6592
Filed: 1989-06-09
Abstract: Disclosed is a process for preparing high molecular weight ethylene-α-olefin elastomers, preferably an ethylene-propylene elastomer, by liquid phase polymerization of the requisite monomers in the presence of a metallocene/alumoxane catalyst system. Preferably, the process is carried out as a slurry polymerization utilizing the metallocene/alumoxane catalyst in supported form on a silica gel support with the α-olefin monomer maintained in liquid state and used in excess to serve as a polymerization diluent. The metallocene component of the catalyst by which the process is practiced is of the formul:
      wherein M is zirconium, titanium or hafnium; each R¹ independently is a C₁-C₂₀ linear, branched or cyclic alkyl group or a C₂-C₄ cyclic alkylene group which forms a fused ring system group; R² is a C₁-C₆ linear, branched or cyclic alkylene, a Si₁-Si₂ alkyl substituted silanylene group or an alkyl substituted silaalkylene group; each X independently is an alkyl, aryl, halide, hydride or oxygen bridge of a zirconocene dimer; "y" is a number 2, 3 or 4, and "b" is a number 0 or 1. M is preferably zirconium. Most preferably, the supported zirconocene/alumoxane catalyst is prepolymerized with ethylene or another olefin to provide spherical, free-flowing catalyst particles which give free-flowing particulate elastomer product from the slurry polymerization.

Title: Dispositif de commande d'un verin hydraulique à double effet
Inventor: KERVAGORET GILBERT BENDIX FRAN
IPC: B62D7/14
Filed: 1989-03-15
Abstract: L'invention est relative à la commande d'un vérin hydraulique utilisable par exemple pour la commande de l'orientation des roues arrière d'un véhicule à roues avant directrices. En cas de défaillance de l'alimentation en fluide sous pression des chambres (3, 4) du vérin, ces chambres sont isolées et le piston (2) est maintenu dans la position qu'il occupait lors de l'apparition de la défaillance, grâce à des clapets anti-retour (12). Toutefois, lorsque certaines conditions sont remplies, par exemple une vitesse suffisamment réduite, l'organe de commande électronique (20) met en route un circuit auxiliaire (30 à 39) pour ramener le piston dans sa position médiane et permettre une conduite de type classique avec les roues arrière en ligne.

Abstract: Un circuit d'unité logique à transistors à effet de champ couplés à une source de rétro-action comporte une tension de référence interne fournie par la sortie de l'un des transistors à effet de champ d'une paire de transistors à effet de champ, connectés via un transistor à effet de champ suiveur de source à l'entrée de l'autre transistor à effet de champ de la paire. Les circuits d'une unité logique couplée à une source de rétro-action présente par rapport aux circuits des unités logiques à transistors à effet de champ couplées à une source connues des avantages dus à une densité supérieure de fonctions pour une surface donnée de circuits intégrés, une dérivation de tension inférieure lors de changements de température, un gain de tension supérieur, une marge de bruit supérieure et une charge de sortance supérieure. La sortie de l'un des transistors à effet de champ est connectée via un transistor à effet de champ suiveur de source à l'entrée de l'autre transistor à effet de champ de la paire.

La teneur en matière grasse de la fraction à forte teneur en matière grasse est déterminée et la teneur en matière grasse de la fraction à faible teneur en matière grasse est maintenue à un niveau négligeamment faible, le débit volume de la fraction à faible teneur en matière grasse est déterminé, puis une part précise de la fraction à forte teneur en matière grasse est ajoutée à la fraction à faible teneur en matière grasse pour obtenir du lait à teneur en matière grasse désirée (lait standardisé), et la part restante de la fraction à forte teneur en matière grasse (crème) est évacuée à travers une vanne de régulation (8). Ledit procédé se caractérise en ce que la part de la fraction à forte teneur en matière grasse ajoutée à la fraction à faible teneur en matière grasse est réglée au moyen d'une vanne de régulation (12) qui, en conjonction avec la vanne de régulation (8) servant à l'évacuation de la partie restante de la fraction à forte teneur en matière grasse, est commandée sur la base du débit volume (10) de la fraction à faible teneur en matière grasse, sur la base du débit volume (11) de la partie de la fraction à forte teneur en matière grasse ajoutée à la fraction à faible teneur en matière grasse, ainsi que sur la base de la mesure de densité (7) de la fraction à forte teneur en matière grasse, de sorte que la densité de la fraction à forte teneur en matière grasse, et par conséquent la teneur en matière grasse, est maintenue à une valeur fixée.

Title: Improved stabilizers for halogen-containing polymers.
Inventor: SILBERMANN JOSEPH
IPC: C08J5/00
Filed: 1989-10-06
Abstract: Improved stabilizer compositions are provided which impart significant long-term heat stabilization to halogen-containing vinyl polymers such as polyvinyl chloride. The improved stabilizer compositions combine one or more metal-containing primary stabilizer compounds with a finely divided co-stabilizing phosphate material of a predetermined surface area. The phosphate material includes an anhydrous or hydrous sodium or potassium monohydrogen phosphate, lithium dihydrogen phosphate, or alkali-metal pyrophosphate. The novel combination of stabilizers enables a reduction in the amount of metal-containing stabilizer, if desired, while still yielding long-term stability in the resultant polymer, or provides the ability to raise process temperature and reduce cycle times of molding operations.
