Abstract: A process is described for ultrapyrolytic upgrading of a heavy hydrocarbon oil feedstock by contacting the feedstock in a confined riser vertical column with finely divided inert solid particles under ultrapyrolysis conditions, the riser forms part of an internally circulating aerated bed reactor with the bottom end of the riser being directly connected to an inlet nozzle feeding the heavy hydrocarbon oil feedstock and the upper end of-the riser extending above an annular aerated bed of the finely divided solid particles surrounding the riser.  The riser also includes a plurality of orifices in a lower region thereof flow connected to a lower region of the aerated bed for controlled delivery of the particles from the aerated bed into the riser.  The novel feature comprises continuously feeding an atomized stream of the heavy hydrocarbon oil feedstock upwardly through the inlet nozzle into the riser, continuously feeding finely divided solid heat carrier particles from the annular aerated bed into the riser through the orifices, contacting the particles and atomized feed within the riser under ultrapyrolysis conditions, continuously maintaining a level of particles in the aerated bed such that there is a net positive pressure difference between the aerated bed and the riser at the level of the orifices whereby riser gases are prevented from escaping into the annular bed, continuously removing particles and product gas from the upper end of the riser, continuously recycling the removed particles into the aerated bed and continuously withdrawing product gas from the system.

Abstract: Un dispositif rétractable automatiquement en permanence (10) et destiné à recueillir un fluide, présente un élément de protection externe tubulaire allongé (12) pourvu d'une extrémité frontale (14) dotée d'un orifice (15) et d'un piston télescopique coaxial (16) muni d'une extrémité frontale (26) conçue pour s'engager par friction dans un support d'aiguille (20) pour aiguille de canule (32). Le piston est monté coulissant dans l'élément tubulaire allongé afin de permettre un mouvement sélectif dans un sens axial, vers l'avant et vers l'arrière. L'extrémité frontale du piston présente un orifice dont les surfaces de contact sont dirigées vers l'intérieur (66) afin qu'elles s'engagent par friction dans les surfaces de contact orientées vers l'extérieur (68) de la périphérie du support d'aiguille (20), le long d'une interface coulissante orientée dans l'axe. Lorsque le piston est déplacé vers l'avant afin de faire sortir l'aiguille de l'orifice, un dispositif de blocage (48)(50) le maintient dans une première position. Un effet de ressort est appliqué sur le support d'aiguille maintenu par friction à l'extrémité frontale du piston. Un tube collecteur (72) peut être monté dans l'orifice (40) situé à l'arrière du piston. Après le prélèvement de l'échantillon et le retrait du tube collecteur, un capuchon de piston (42) est replacé afin de permettre au piston de passer d'une première à une seconde position, ce qui entraîne, par un mouvement coulissant, la séparation du piston et du support d'aiguille le long de l'interface coulissante. L'effet de ressort étant supérieur à la force de friction résiduelle au niveau de l'interface coulissante, le support d'aiguille se rétracte de façon immédiate et permanente dans une cavité comportant un espace de rétraction (17) à l'intérieur du piston.

Title: Imaging apparatus and method and liquid toner therefor
Inventor: BOSSIDON BECKY
IPC: G03G9/135
Filed: 1994-12-29
Granted: 2005-10-25
Abstract: Scuff resistance, abrasion resistance and peel resistance of a wide class of liquid toners may be improved by the addition of a minor amount of an additional material which, at the fusing temperature used for the toner, has a much lower viscosity, preferably several orders of magnitude lower, than the viscosity of the toner particles at the fusing temperature and which forms a separate phase from the toner particles when solidified. It is believed that such material, during the fusing process, migrates to the outer surface of the image. During cooling of the image after it is fused, the additional material forms a substantially separate phase resulting in a hard slippery coating of the additional material which protects the image from abrasion.
