Title: Soupape de derivation pour fond de trou
Inventor: GILLIES IAN
IPC: E21B21/10
Filed: 2000-02-25
Granted: 2008-07-15
Abstract: L'invention concerne des soupapes de dérivation pour puits de forage, en particulier mais non exclusivement des soupapes de dérivation utilisées pendant la mise en place de packers hydrauliques à coins d'ancrage. Une soupape (2) de dérivation comprend un piston (30) coulissant, monté dans une position adjacente à une partie (4) du corps comprenant au moins une ouverture (20) traversante. Le piston (30) peut être déplacé entre une première position dans laquelle un passage est établi entre l'intérieur du corps (4) et l'extérieur de ce dernier via cette/ces ouverture(s) (20) et une seconde position dans laquelle l'intérieur du corps (4) est isolé de l'extérieur. Des moyens permettent, en réponse à un différentiel de pression prédéterminé du fluide dans la longueur du piston (30), d'augmenter la force appliquée sur le piston (30) par une vitesse de circulation donnée du fluide à travers la soupape (2), de manière que la force résultante appliquée sur le piston (30) soit insuffisante pour déplacer le piston (30) dans la seconde position. Ainsi cette soupape (2) de dérivation permet d'envoyer à la surface une indication d'une fermeture imminente. Lorsque cette indication est reçue, la soupape (2) de dérivation peut être fermée par une simple augmentation de la vitesse de circulation du fluide sans qu'il soit nécessaire de procéder à des actions compensatoires.

Abstract: The invention is a modular truck sleeper assembly that allows truck sleepers of various sizes and trim levels to be built on the same assembly line by pre-assembling the floor and sides and connecting them together during final assembly. A floor made up of a plurality of cross-members attached, with a predetermined distance between the cross-members, to a plurality of sills, with a first member of a foot/shoe combination attached to each of the cross-members' ends, is previously assembled and groomed with panels and cabinetry. A plurality of sides made up of a bottom stringer, a top stringer, and a plurality of risers attached, with the same predetermined distance between the risers, between the bottom stringer and the top stringer, with a second member of the foot/shoe combination attached to each of the riser ends, are also previously assembled and groomed with panels and cabinetry. The sides and floor of the modular truck sleeper assembly are then assembled by attaching the corresponding members of the foot/shoe combinations together. The length of the assembled sleeper is substantially equal to an integral multiple of the predetermined distance.

Abstract: A method and system for recovering fines from a light FCC-type effluent gas. Cracked gases from the reactor are cooled by direct contact with circulating oil in an oil quench tower. The circulating oil also washes out the catalyst fines carried with the reactor effluent gas. A flow of the oil from the quench tower bottoms is sent through one of a pair of filters to remove fines and recycled to the tower. The other filter is in backwash operation using a compressed gas to remove the fines therefrom and into a surge drum. Fuel oil or quench oil is added to the drum to form a slurry, which carries the catalyst fines to the regenerator where the oil is combusted to supply the FCC system heat requirements. Since a minimum amount of fuel oil is generated in the FCC, fuel oil is imported to inventory the quench tower.

Title: Method of applying marking agent to aluminum sheet for scrap sorting purposes
Inventor: WHEELER MICHAEL J
IPC: B07C5/34
Filed: 2002-03-26
Granted: 2007-02-06
Abstract: Application of a marking agent to metal stock, such as aluminum sheet, durin g and as a part of procedures for preparing the sheet for subsequent, scrap- generating manufacturing operations, to provide a detectable mark on pieces of manufacturing scrap derived from the marked sheet and commingled with scrap of other aluminum alloy sheet, so that the scrap can be sorted and the marked alloy scrap pieces separated from scrap of other alloy sheet to which the marking agent was not applied. Different marking agents, providing detectabl y different marks, may be respectively applied to sheet of different compositions if scrap pieces of more than two different compositions or compositional families are to be sorted and separated from each other. The marking agent may be added to a lubricant or prelubricant conventionally applied to the sheet by the sheet producer prior to delivery to the manufacturing customer. If an indelible marking is applied selectively only to areas of the sheet stock that will be scrapped, it can be safely retained throughout the manufacturing operation without affecting the final produced article.

Abstract: A system and method are used in connection with processing of blood components. The processing of blood components may involve centrifugal separation and/or filtering of the blood components. In some examples, at least some blood components are centrifugally separated in a chamber and then filtered via a filter (31) rotating along with a centrifuge rotor (1), wherein the filter is located closer than the chamber to an axis of rotation of the rotor. The filter may include a porous filtration medium configured to filter leukocytes, platelets, and/or red blood cells. Some examples include a pressure sensor sensing pressure of pumped blood components. The sensed pressure may be used in connection with controlling the pumping of the blood products and/or in connection with determining the location of an interface associated with the blood products. Other uses of the sensed pressure are also possible.
