Abstract: Sealing arrangement for use with a rotatable machine element for maintaining a medium in a sealed space. The sealing arrangement includes a sealing surface on the machine element and a radially sealing ring having a polymeric sealing lip for engagement with the sealing surface. The sealing lip has a sealing edge defined by a pair of intersecting first and second conical surfaces, whereby the first conical surface is directed towards the sealed space and encloses a first angle with the axis of rotation which is steeper than the cone angle of the conical surface directed away therefrom. A helical groove with rounded base is machined into the sealing surface, whereby the groove base has a radius of curvature of 0.4 to 1.6mm and the depth of the groove is less than 15µm. The seal arrangement provides improved sealing characteristics and an extended service period due to reduced wear of the sealing edge.

Abstract: An ink containment and dispensing device for an ink-jet printer is provided with a main reservoir in the form of a flexible pouch, which is typically maintained at ambient pressure. The main reservoir is coupled to a variable volume chamber via a one-way valve which allows the flow of ink from the reservoir to the chamber and prevents the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet, which is normally closed to prevent the outward flow of ink.  However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer. The pump has a linearly acting pumping member and a flexible diaphragm that overlies the pumping member, the diaphragm being impervious to the transmission of oxygen and moisture therethrough to prevent degradation of the ink within the chamber. The flexible pouch is contained within a rigid, outer shell having an opposed pair of shorter sides interspersed with an opposed pair of longer sides, and the shorter sides of the shell, in the region of the closed end of a cup-shaped shell, are configured for grasping and for identifying the location of the closed end of the shell.

Abstract: A method for reducing the severity of host vs. graft reaction (HVGR) by the transplant recipient of donor organ or tissue by the transplant recipient and is based on the discovery that hsp60 autoimmunity c an function as an accelerator of foreign immunity and the down-regulation of hsp60 autoimmunity suppresses or prevents the graft rejection reaction. Administration of any composition which causes the down-regulation of hsp60 autoimmunity, such as hsp60 or peptide p277 in a tolerogenic carrier or a biologically active carrier capable of mediating a TH1~TH2 shift, will thus reduce the severity of HVGR.

Title: Method for producing an antibacterial metallic article and such an antibacterial metallic article produced by this method
Inventor: YOKOTA TAKESHI
IPC: A01N25/34
Filed: 1998-11-10
Granted: 2003-05-27
Abstract: An excellent antibacterial property is afforded upon a metallic article by simple steps of coating a dispersion liquid or a solution of fine particles made of an antibacterial ingredient on the surface of the metallic article and pressing the resulting coated surface of the metallic article under a non-heated condition or rubbing the resulting coated surface of the metallic article. In addition, a conventional rolling step or the like can be used itself without any change in the above treatment, which is economically extremely advantageous. Furthermore, since the antibacterial metallic article according to the present invention is obtained under the non-heated condition, the antibacterial ingredient is not deteriorated. Further, since the antibacterial property is not lost through some abrasion, excellent antibacterial property can be exhibited over an extended time period. Further, there is no fear that surface characteristics of the metallic article, for example, a tone of color will change.

Title: Snap-on screw-off closure
Inventor: LONG CHARLES J JR
IPC: B65D41/58
Filed: 1998-10-29
Granted: 2007-08-21
Abstract: The present invention provides a closure with a thread configuration adapted for snap-on or screw-on application to a container neck finish. Preferably the closure and neck finish contain eight or nine mating continuous or discontinuous threads for this purpose. The present invention preferably provides at least one annular sealing bead depending from the outer surface of the closure valve which are compressed against the inner surface of the container neck to form a seal as the closure is snapped onto the container neck. Elevated areas extend upwardly from the tamper-evident band in spaced relation to the bottom edge of the closure body to support the tamper-evident band in resisting vertical movement imparted by insertion of the closure on the bottle neck, thereby protecting the frangible elements during assembly. At least one lug (18) optionally extends from the exterior wall of the container neck to facilitate breaking the frangible elements on the tamper-evident band of the closure by engaging the frangible elements (35) as the closure is twisted off the container neck following initial snap-on application.

Title: Large round baler net wrapping apparatus having net roll pressure arm serving also as a loading platform
Inventor: PAZ ZVI
IPC: A01F15/07
Filed: 2000-06-01
Granted: 2005-03-22
Abstract: The use in prior art net wrapping apparatus of an idler roll located between the supply roll of wrap material and the feed rolls for delivering the net for wrapping a bale located in the baling chamber of a large round baler is not desirable since it is difficult to thread the net about this idler roll when a new supply roll of wrap material is loaded into place on the baler. The invention permits the omission of such an idler by providing a biasing arrangement including a pressure roller, carried by lower arm portions of a lower arm section, which engages and presses the supply roll or wrap material directly against the upper feed roll. The force pressing the pressure roll against the supply roll originates with gas springs coupled to a linkage that is in turn coupled to transversely spaced upper arm portions of an upper arm section, these upper arm portions carrying respective force transfer rollers that engage respective intermediate sections of the lower arm portions.

Inventor: WHITEHURST DARRELL DUAYNE
IPC: C10G25/12
Filed: 2000-06-01
Granted: 2011-04-19
Abstract: Described herein is a combined process for improved hydrotreating of diesel fuels, in which the feed to be hydrotreated is pretreated with a selective adsorbent prior to the hydrotreating step to remove polar materials, especially nitrogen containing compounds (N-compounds). By removing the N-compounds in this way, it is possible to achieve extremely high conversions of refractory sulphur compounds in the diesel fuel at moderate hydroprocessing conditions. If the diesel fuel is hydrotreated without prior removal of N-compounds, excessive amounts of hydrotreating catalysts must be used and high temperatures and pressures must be employed. This is particularly true when sulphur levels of below 500 ppm are desired. The selective adsorption process can employ either liquid or solid adsorbents, and may be operated in a variety of modes, including stirred tanks, hydroclones, moving beds, fixed beds, ebulated beds or fluidized beds. In operations, where the adsorbent and diesel fuel are both moving through the reaction adsorption zone, the flows can be either cocurrent or countercurrent. After contact of the adsorbent with the diesel fuel feed, the adsorbent containing undesired polar compounds is separated from the diesel fuel and the inhibitor free fuel is processed in conventional equipment. The separated adsorbent is then subjected to a two step procedure for regeneration. First any physically adsorbed inhibitor free fuel is recovered. For example, if a solid adsorbent is employed, the solid containing physically adsorbed diesel fuel is contacted with a stripper gas such as steam to strip off the inhibitor free fuel, while leaving the polar compounds strongly adsorbed on the solid adsorbent. The polar compounds may then be removed either by a oxygenative or hydrogenative process.
