Abstract: Striped films of the invention can have two or more preferably polymeric layers, of which at least one continuous or discontinuous layer includes a pigmented resin. The striped film is produced by modifying conventional coextrusion dies to restrict the flow of a pigmented melt stream. The result is a striped film useful for identifying the contents of a package made from the film, tamper evidence, counterfeit protection and verification of properties.      The stripes can be of one or more colors, and vary in width and spacing. The pigment can be a material visible in ordinary light, or a material invisible in ordinary light but visible in e.g. ultraviolet light.

Title: Immunosuppression by blocking t cell co-stimulation signal 2 (b7/cd28 interaction)
Inventor: LECHLER ROBERT IAN
IPC: A61P37/06
Filed: 1999-04-30
Granted: 2015-12-15
Abstract: The invention provides means and methods for inhibiting T-cell mediated rejection of a xenotransplanted organ by blocking the delivery of co-stimulatory signal 2 (the B7/CD28 interaction) in order to prevent the activation of xenoreactive T-cells in the recipient. In a first aspect, co-stimulation is prevented by administration to the organ recipient of a soluble form of CTLA-4 from the xenogeneic donor organism. This preferentially binds B7 on the xenograft and blocks the interaction between B7 on the xenogeneic donor cells and CD28 on recipient T-cells. In a second aspect, co-stimulation is antagonised by expressing a ligand for CTLA-4 on the xenogeneic donor cells. This ligand binds to CTLA-4 on activated T-cells of the recipient and antagonises signal 2. In a third aspect, co-stimulation is prevented by expressing recipient organism MHC class II on the surface of the cells of the xenogeneic donor organ. The donor cells are thus able to present xenoantigens to a recipient T-cell in the context of self-MHC class II. If the donor cells do not express B7, or if B7 is blocked, the xenoreactive recipient T-cell becomes anergic.

Abstract: A switch assembly includes a housing within which is arranged a convex, over-center spring which deforms when pressure is applied to a push button. In a default position, the push button sits atop an apex of the spring, with the spring being spaced from a contact associated with a first electrical lead. One end of the spring projects from the housing and defines a second electrical lead. When pressure is applied to the push button, the spring is pushed into electrical communication with the contact, thus completing a circuit between the electrical leads. In a first embodiment, a base housing member and a separate snap-on cover is provided. In a second embodiment, the cover is attached to the base housing via a living hinge. In both the first and second embodiments, the cover assists in holding the spring in the default position.

Title: End cap relief valve mechanism for a filter
Inventor: SCHWARZLOSE RICHARD
IPC: B01D35/147
Filed: 2002-03-05
Granted: 2006-11-28
Abstract: An oil filter comprises a housing that is open at one end and has an end plate connected to the housing for closing the open end. The end plate has at least one inlet opening and an outlet opening therein. An anti-drain back valve is provided for precluding return flow of oil through the inlet opening. An annular filter media is disposed in said housing. An end cap is provided at each end of the filter media. The end cap remote from the end plate has at least one opening spaced radially outwardly from the central axis thereof. A spring cooperates with said end cap remote from the end plate. Normally, the opening in the spring is closed to oil flow. When the filter media becomes clogged, the pressure within the housing increases and when the pressure differential across the end cap remote from the end plate exceeds a predetermined value, the opening in the spring is opened for oil flow. The anti-drain back valve is disposed between the end cap adjacent the end plate and the end plate and the spring is constructed and arranged to engage the interior of the housing so as to load the filter media and the end cap adjacent to the end plate to help retain the anti-drain back valve in place. The spring and the end plate remote from the end plate provide the end cap relief valve mechanism and are constructed and arranged to operationally interengage and provide a relatively flat profile. A thermal sensitive material disposed between the end cap and the spring will hold the end cap and spring and preclude oil flow through the cap until a predetermined temperature of the oil is attained during initial operation of the engine. This will help remove contaminants that may be present in the engine during initial operation of the engine with which the fluid filter is used.      Thereafter, the end cap and spring will operate to open in response to predetermined pressure differential across the end cap.
