IPC: A01D69/08
Filed: 2000-10-26
Abstract: A self-propelled forage harvester has a relatively wide mowing implement attached to its forward end and including right and left hand rotary mowing and drawing in drums together with right and left hand rotary conveying drums. A drive transmission for driving these drums includes a pair of identical slip clutches having respective first sections defined in principal part by a fluid tight cylindrical container having opposite end plates and through the respective centers of which a drive element extends, with the drive element of one clutch being coupled to the drive element of the other clutch by a central drive shaft assembly. The clutches include respective second sections which are in the form of a housing which has a ring-like hub at one end adapted for being coupled to an associated right-angle transmission unit that is in turn coupled for driving the mowing and drawing in drums at that side. The first and second sections of each clutch are drivingly interconnected by a pair of friction disks mounted for rotation with the second section and respectively biased into friction locked engagement with the opposite end plates forming part of the container by a spring assembly mounted in an end of the housing remote from the ring-like hub.

Title: Staged venting of fuel cell system during rapid shutdown
Inventor: DOAN TIEN M
IPC: B60L11/18
Filed: 2001-01-05
Abstract: A venting methodology and system for rapid shutdown of a fuel cell apparatus of the type used in a vehicle propulsion system. H2 and air flows to the fuel cell stack are slowly bypassed to the combustor upon receipt of a rapid shutdown command. The bypass occurs over a period of time (for example one to five seconds) using conveniently-sized bypass valves. Upon receipt of the rapid shutdown command, the anode inlet of the fuel cell stack is instantaneously vented to a remote vent to remove all H2 from the stack. Airflow to the cathode inlet of the fuel cell stack gradually diminishes over the bypass period, and when the airflow bypass is complete the cathode inlet is also instantaneously vented to a remote vent to eliminate pressure differentials across the stack.

Patent CA-2339132-A1 (CA)
Inventor: NILSSON LARS-GUNNAR
IPC: A61M15/02
Filed: 1999-07-08
Abstract: The invention discloses a method and a device for classification and, if required, electrostatic charging of a resulting separated decomposed powder preferably in the form of a substance intended for inhalation purposes. The classification takes place in that the powder is released from a device decomposing the suitable substance, whereby the powder is given a velocity perpendicular to an applied electric field (8). By adapting the strength of the electric field decomposed powder, i.e. individual particles resembling dust, will by means of the electric field (8) be attracted to a device (9) from which dosing of the individual particles then takes place. Larger particles (agglomerates) then will proceed straight ahead in an initial velocity direction as their kinetic energy is essentially larger than that f or the small particles. In this manner a desirable separation of individual particles is obtained from the heavier agglomerated particles not desired to  be administered and the conditions for a very good dosing of the substance thereby will result.

Title: Modulation of systemic memory t cell trafficking
Inventor: BUTCHER EUGENE C
IPC: A61P17/02
Filed: 2000-01-14
Abstract: methods are provided to specifically modulate the trafficking of systemic memory T cells, particularly CD4+ T cells, without affecting naive T cells o r intestinal memory T cells. It is shown that systemic memory T cells, which a re characterized as CD45Ra-, and integrin .alpha.4.beta.7-, express high levels  of CCR4. Ligands or CCR4, such as TARC or MDC, act as an adhesion trigger, wherein upon CCR4 binding, these cells undergo integrin-dependent arrest to the appropriate vascular receptor(s). This arrest acts to localize the cells  at the target site. The methods of the invention manipulate this triggering,  and CCR4 mediated chemotaxis, to affect the localization of T cells in targeted tissues. In one embodiment of the invention, the active agent is a CCR4 agonist, that acts to enhance T cell localization. In an alternative embodiment, the agent is an antagonist that blocks CCR4 biological activity.  An advantage of the invention is the selectivity for systemic memory T cells , without affecting native T cells or intestinal memory T cells.

Abstract: A method is described for determining recirculation of blood in a vascular access (11) of a patient undergoing dialysis treatment by means of a dialysis machine (10) comprising an arterial line (24) for withdrawing blood from the patient's body, a dialysis filter (16), and a venous line (26) for returning the blood to the patient's body. The present method consists in inducing, in the blood flowing in the venous line (26), a disturbance of a magnitude such as to bring the system into a transient state and determining blood recirculation in the vascular access (11) during the transient state as a function of the magnitude of the disturbance induced in the arterial line (24). In particular, the aforesaid disturbance consists of the variation of the haemoglobin concentration in the blood flowing in the venous line (26) and the variation is caused by controlling a change in the ultrafiltration flow in dialysis filter (16).

Title: Method and apparatus for removing oil from water including monitoring of adsorbent saturation
Inventor: JOHNSON MICHAEL R
IPC: B01D/
Filed: 2000-06-07
Abstract: Apparatus in fluid communication with a water leg portion of a hydrocarbon-contaminated water, e.g., a water leg portion of an offshore drilling or production platform sump tank for conveying water, separated from oil, into contact with organophilic clay cannisters such that the hydrocarbons and other organic materials commingled with the sump tank water will be adsorbed onto the organophilic clay and detected by the embedded probe in selected cannisters. The water will pass through the clay and will be conveyed back to the ocean water without contamination. At some point in time, the organophilic clay will become "spent" and at a certain "spent level", the saturated condition of the organoclay will be electronically detected by the embedded probe and alarm/control panel. The alarm indicates that the "spent" organophilic clay should be replaced with fresh clay or the spent clay regenerated.
